Description

Method and device for transmitting data

The present application claims priority to PCT Patent Application No. PCT/CN2018/085917, entitled "Method and Apparatus for Transmitting Data", filed on May 07, 2018, the entire contents of In this application.

Technical field

The present application relates to the field of communications and, more particularly, to methods and apparatus for transmitting data.

Background technique

Ultra-Reliable Low Latency Communication (URLLC) service requires extremely high latency. When there is no reliability requirement, the delay requirement is within 0.5ms. Under the 99.999% reliability requirement, the delay is still It should be within 1ms. In the evolution of the Long Term Evolution (LTE) system, the Short Transmission Time Interval (Short TTI) technology provides the possibility of ultra-short delay communication to a certain extent, and the standard will continue to consider URLLC. The evolution of technology. In the 5G standard, in order to meet such severe delay requirements, shorter scheduling units, such as mini-slots, are defined, that is, one or more orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing) , OFDM) symbol as a scheduling unit, the total OFDM symbol length of the scheduling unit is less than the length of one slot. For example, a slot with a large subcarrier spacing, such as a subcarrier spacing of 60 kHz, a slot having a length of 7 OFDM symbols and a time length of only 0.125 ms.

At present, the shortest data interaction method is that one controller can control multiple terminals (Slaves), and the controller and multiple terminals generally adopt a serial connection topology, in a task time (cycle time) Within the controller, the controller will make all the data of the terminal into a large package, and use the data train mode to serially access each terminal in a certain order. When a terminal receives the data packet, it will parse its corresponding data. At the same time, the data that needs to be fed back is placed in the data packet, and when the entire data packet (data train) is finally returned to the controller, the data interaction in a cycle time is completed.

However, as the number of terminals increases, the time of the entire cycle time increases linearly and the delay increases. In addition, since the serial topology order is fixed, when there is a need for communication between terminals, the upstream terminal can communicate with the downstream terminal, but the reverse is not possible, and it is necessary to wait until the next cycle time.

detailed description

The technical solutions in the present application will be described below with reference to the accompanying drawings.

1 is a schematic diagram of a system 100 for transmitting data suitable for use in embodiments of the present application. As shown in FIG. 1, the system 100 includes at least one master node and at least one slave node (Slave). As shown in FIG. 1, system 100 can include a primary node 110, a first child node 120, a second child node 130, and a third child node 140.

The interaction between the master node and the child nodes can be achieved by transmitting data. The master node and the child node may be a network device and a network device, or a network device and a terminal device, or a terminal device and a terminal device.

The terminal device in the embodiment of the present application may refer to a user equipment, an access terminal, a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent, or User device. The terminal device may also be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), with wireless communication. Functional handheld devices, computing devices or other processing devices connected to wireless modems, in-vehicle devices, wearable devices, terminal devices in future 5G networks, or in the future evolution of the Public Land Mobile Network (PLMN) The terminal device and the like are not limited in this embodiment of the present application.

The network device in the embodiment of the present application may be a device for communicating with the terminal device, and the network device may be a Global System of Mobile communication (GSM) system or Code Division Multiple Access (CDMA). Base Transceiver Station (BTS), which may also be a base station (NodeB, NB) in a Wideband Code Division Multiple Access (WCDMA) system, or an evolved base station in an LTE system (Evolutional The NodeB, eNB or eNodeB) may also be a wireless controller in a Cloud Radio Access Network (CRAN) scenario, or the network device may be a relay station, an access point, an in-vehicle device, a wearable device, and a future. The network device in the 5G network or the network device in the PLMN network in the future is not limited in this embodiment.

At present, mobile communication has profoundly changed people's lives, but the pursuit of higher performance mobile communication has never stopped. In order to cope with the explosive growth of mobile data traffic, massive device connections, and emerging new services and application scenarios, the Long Term Evolution (LTE) system continues to evolve, while the fifth-generation mobile communication (5G) system also It came into being. Different scenarios, different services, and different devices have different requirements for communication networks.

The International Telecommunication Union (ITU) defines three types of services in the 5G expectation and requirements, namely Enhanced Mobile BroadBand (eMBB) and Ultra-Reliable Low (Ultra-Reliable Low). Latency Communication, URLLC) and massive machine type of communication (mMTC). The eMBB service mainly includes ultra-high definition video, Augmented Reality (AR), and Virtual Reality (VR). The main features are large transmission data and high transmission rate. The URLLC service is mainly used for industrial control, driverless, etc. in the Internet of Things. The main features are ultra-high reliability, low latency, low transmission data and burstiness. The mMTC service is mainly used for smart grids and smart cities in the Internet of Things. The main features are the connection of mass devices, the small amount of data transmitted, and the delay of tolerating for a long time.

In addition, with the discussion of the high-reliability and low-latency technology in the 3rd Generation Partnership Project (3GPP), the vertical industry is also paying more and more attention to the progress of the standard in this piece, and the demand for the vertical industry is SA1 proposed TR22.804, which gives some scenarios that require extremely high reliability (6-8 9) and ultra low latency (<2ms) for industrial scenarios, covering industrial motion control (motors, etc.), robots. Collaboration, etc.

At present, there is a master-slave mode, which is a model based on the idea of divide and conquer. This mode is to decompose a task (original task) into several semantically equivalent subtasks, and these tasks are executed in parallel by a special worker thread. The result of the original task is formed by integrating the processing results of each subtask.

Specifically, there are usually three ways to communicate between master-slave.

method one

As shown in FIG. 2, one controller (ie, an example of a Master) controls a plurality of terminals (ie, an example of a Slave), and the controller and the plurality of terminals generally adopt a serial connection topology manner in a task time unit (cycletime). Within the controller, the controller will make all the data of the terminal into a large package, and use the data train mode to serially access each terminal in a certain order. When a terminal receives the data packet, it will parse its corresponding data. At the same time, the data that needs to be fed back is placed in the data packet, and when the entire data packet (data train) finally returns to the controller, the data interaction within one task time unit is completed.

Master and multiple slaves use serial communication. As the number of slaves increases, the time of the entire cycleTime increases linearly, which has a great impact on the productivity of automated industrial control. In addition, since the serial topology order is fixed, when there is a need for communication between the slaves, the upstream Slave can communicate with the downstream Slave, but the reverse is not possible, and it is necessary to wait until the next cycle time.

Way two

As shown in Figure 3, most of the current device-to-device (D2D) cooperation modes are configured by the base station to allocate resources for the target terminal group, and the connections and data transmission between the terminals are The base station is required to perform scheduling.

There is also a way for the terminal to cooperate. In the unlicensed spectrum, the terminal uses a Listen-before-Talk (LBT) method. That is, before the terminal sends data, it needs to listen to whether other terminals are transmitting data, and initiate data when it is determined that the channel is idle.

From the two typical terminal collaboration technologies of the currently licensed (Licensed) spectrum and the Unlicensed spectrum, whether it is based on scheduling terminal cooperation or based on unscheduled but LBT-based collaboration, additional time overhead is required, so for industrial control This scenario where the cycle time delay is less than 2ms is still not applicable.

Way three

The operations of receiving/transmitting each transmission time interval (TTI) of each terminal are semi-statically configured to perform cooperative forwarding between terminals. The third method is to semi-statically configure the listening and sending status of each terminal. All terminals still use the time-division method for cooperative transmission, so the delay is large and the resource utilization is not high. In addition, each terminal in the third mode can only listen to or send data of one terminal at the same time, and cannot transmit its own and collaborative data at the same time, so the spectrum utilization rate is also low.

Based on the defects of the foregoing three modes, the embodiment of the present application provides a method for transmitting data, which can greatly reduce the delay of the cycle time and improve the efficiency. FIG. 4 is a schematic flowchart of a method for transmitting data applicable to an embodiment of the present application.

The receiving end (Slave) includes two types of channel types: a data channel and a control channel.

In the data channel, when the receiving and receiving state of the receiving end is the receiving state, the user data is used to receive the command data of the user from the configured common resource; and the command data and/or the feedback data of the cooperative user are received by using the cooperative resource.

In the data channel, when the receiving and receiving state of the receiving end is the transmitting state, on the one hand, the receiving end can use the user resource to send feedback data for the command data from the configured common resource. In addition, after receiving the feedback data, the transmitting end may also decode the feedback data. If the decoding fails, the transmitting end may send control data for the feedback data, for example, may send unconfirmed (Non-Acknowledgement , NACK) information. If the receiving end receives the NACK information, the receiving end retransmits the feedback data of the user, so that the transmitting end can correctly decode. On the other hand, the receiving end may also use the cooperative resource to receive feedback information of other cooperative receiving ends, and determine the receiving and transmitting state of the receiving end according to the feedback information.

It should be understood that, in the embodiment of the present application, the data sent from the sending end (or the master node Master) to the receiving end (or the child node master) is represented by the command data, and the data sent from the receiving end to the sending end is represented by the feedback data. The control data is used to indicate the data sent by the transmitting end to the receiving end for the feedback data. In other words, the command data and the feedback data may both be data signals, only the corresponding transmission directions are different, and there is no necessary sequence. Control data, such as ACK/NACK, is control information indicating whether the command data or feedback data is decoded correctly.

On the control channel, the receiving end transmits and receives control data from the configured common resources.

FIG. 4 is only an exemplary illustration, and the method for transmitting data in the embodiment of the present application is specifically described in the following embodiments.

In addition, the technical solutions of the embodiments of the present application can be applied to various communication systems, for example, a Global System of Mobile communication (GSM) system, a Code Division Multiple Access (CDMA) system, and a broadband code division. Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, LTE Frequency Division Duplex (FDD) system LTE Time Division Duplex (TDD), Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) communication system, the fifth generation of the future (5th Generation, 5G) system or New Radio (NR).

It should be understood that the system illustrated in FIG. 1 is merely illustrative and should not be construed as limiting the application. The number of the primary node and the child nodes and the manner of deployment are not particularly limited in this application.

It should be understood that the system shown in FIG. 1 is only one possible application scenario of the embodiment of the present application, and should not be construed as limiting the present application.

In order to facilitate the understanding of the embodiments of the present application, the following briefly introduces several concepts mentioned in the embodiments of the present application.

1, the minimum scheduling time unit

The minimum scheduling time unit refers to the resource granularity in the time domain. A time unit (also referred to as a time domain unit) may be, but is not limited to, a symbol, or a mini-slot, or a slot, or a subframe, or a Frame. The duration of one subframe in the time domain may be 1 millisecond (ms), one slot is composed of 7 or 14 symbols, and one mini slot may include at least one symbol (for example, 2 symbols or 4 symbols) Symbol or 7 symbols or 14 symbols, or any number of symbols less than or equal to 14 symbols).

2, symbol

The symbol refers to the smallest unit of time domain resources. The embodiment of the present application does not limit the length of time of one symbol. The length of one symbol can vary for different subcarrier spacing. The symbols may include uplink symbols and downlink symbols. By way of example and not limitation, the uplink symbols may be referred to as Single Carrier-Frequency Division Multiple Access (SC-FDMA) symbols or Orthogonal Frequency Division Multiple Access (Orthogonal). Frequency Division Multiplexing (OFDM) symbols; downlink symbols may be referred to as OFDM symbols, for example. In the embodiment of the present application, the symbol may be another example of the resource unit.

3, task time

In the embodiment of the present application, the cycle time may refer to the time required to complete a complete interaction. A plurality of small time units can be included in one cycle time. The embodiment of the present application is described by taking a task time unit as an example. It should be understood that the present application does not limit one task time unit.

4, resource unit

A resource unit that can be used as a unit of measure for resources that are occupied by resources in the time domain, frequency domain, or time-frequency domain. In the embodiment of the present application, the resource unit may represent the resource granularity in the frequency domain, as shown in FIG. 5. The resource unit may be, but not limited to, a resource block (RB), a resource block group (RBG), a physical resource block (PRB), a virtual resource block (VRB), a resource. A resource (Resource Element, RE), a subcarrier, a subband, and the like.

5, resource particles

A Resource Element (RE) can also be called a resource element. One symbol can be corresponding to the time domain, and one subcarrier can be corresponding to the frequency domain. In the embodiment of the present application, the RE may be an example of a resource unit.

6, resource blocks

One RB occupies N ^RB consecutive subcarriers in the frequency domain. Where N ^RB is a positive integer. For example, in the LTE protocol, N ^RB can be equal to 12. In this embodiment of the present application, the RB may be defined only from the frequency domain resource, that is, the number of time domain resources occupied by the RB in the time domain is not limited. In the embodiment of the present application, the RB may be another example of the resource unit.

It should be noted that, in the implementation of the present application, the “protocol” may refer to a standard protocol in the communication field, and may include, for example, the LTE protocol, the NR protocol, and related protocols used in a future communication system, which is not limited in this application.

It should be noted that, in the embodiment of the present application, “pre-definition” may be implemented by pre-storing corresponding codes, tables, or other manners that can be used to indicate related information in a device (for example, including a terminal device and a network device). This application does not limit its specific implementation. For example, pre-definition can be defined in the protocol.

It should also be noted that in the embodiments of the present application, the terms "network" and "system" are often used interchangeably, but those skilled in the art can understand the meaning thereof. Information, signals, messages, and channels can sometimes be mixed. It should be noted that the meanings to be expressed are consistent when the distinction is not emphasized. "of", "corresponding (relevant)" and "corresponding" can sometimes be mixed. It should be noted that the meaning to be expressed is consistent when the distinction is not emphasized.

It should also be noted that, in the embodiment of the present application, “master node”, “master”, and “M” are often used interchangeably. It should be noted that when the difference is not emphasized, the meanings to be expressed are consistent. “Sub-nodes”, “Slave”, and “S” are often used interchangeably. It should be noted that when the distinction is not emphasized, the meanings to be expressed are the same.

It should also be noted that in the embodiments of the present application, "reporting" and "feedback" are often used interchangeably, but those skilled in the art can understand the meaning thereof. For the terminal device, the Acknowledgement (ACK)/NACK, and the feedback ACK/NACK can all be substantially ACK/NACK. Therefore, in the embodiments of the present application, the meanings to be expressed are consistent when the distinction is not emphasized.

It should also be noted that “and/or” describes the association relationship of the associated objects, indicating that there may be three relationships, for example, A and/or B, which may indicate that A exists separately, A and B exist simultaneously, and B exists separately. These three situations. The character "/" generally indicates that the contextual object is an "or" relationship. "At least one" means one or more; "at least one of A and B", similar to "A and/or B", describing the association of associated objects, indicating that there may be three relationships, for example, A and B. At least one of them may indicate that A exists separately, and A and B exist simultaneously, and B cases exist separately. The technical solutions provided by the present application will be described in detail below with reference to the accompanying drawings.

It should be understood that in the present application, the first, second, third, etc. are only for facilitating the distinction between different objects, for example, distinguishing different slaves, different data, etc., and should not constitute any limitation to the present application, for example, the first data. The command data may be included as well as the feedback data; or the first data may include data of at least two nodes.

It should be understood that the method of transmitting data provided by the present application is applicable to a communication system, such as system 100 shown in FIG. For example, the present application can be applied to an application scenario that requires high reliability and low latency, and is not limited to industrial motion control, robot cooperation scenarios, and can also be used in other typical terminal cooperation, wireless mesh network (Mesh) and the like. In addition, the present application can be used in various combinations of Master and Slaves, network devices and terminal devices, network devices and network devices, terminal devices, and terminal devices.

The master node in the embodiment of the present application can communicate with one or more child nodes at the same time. For example, the master node (ie, an example of the third node) in the embodiment of the present application may correspond to the master node 110 in FIG. 1 . The child nodes (ie, an example of the first node) in the embodiment may correspond to any one or more of the child node 120, the child node 130, and the child node 140 in FIG.

In the following, without loss of generality, a method for transmitting data according to an embodiment of the present application will be described in detail by taking an interaction process between a master node and three child nodes as an example.

FIG. 6 is a schematic diagram of a method 200 of transmitting data provided by an embodiment of the present application. As shown, the method 200 shown in FIG. 6 can include steps 210, 220.

210. The first node receives the first data by using the first frequency band, where the destination node of the first data is the first node.

220. The first node receives the second data by using the second frequency band, and the destination node of the second data is the second node.

The first child node (ie, an instance of the slave or the first node) and the master node (ie, an instance of the master) or the second child node (ie, an instance of the second node) transmit data through pre-configured Public resources for data transmission. The common resource parameter (that is, an example of the configuration parameter) may be configured by the master node, or may be configured by other network devices, which is not limited in this embodiment of the present application.

Specifically, the first node receives the first data of the first node on a first resource allocated to the first node in a first time period, and receives the first data on a second resource allocated to a second node The second data of the two nodes; the first node sends the second data on the second resource in a second time period according to the first rule; wherein the first rule includes one or more of the following: Sending the second data if the first data is successfully received or decoded correctly, and sending the second data if receiving the first feedback information indicating that the second data is failed to be received; if the current time period is Transmitting the second data in the second time period; and sending the second data if the urgency of the second data meets an emergency condition.

It should be noted that the transmission mentioned in the embodiment of the present application may refer to data transmission from a primary node to a child node, data transmission from a child node to a primary node, or may refer to a child node to a child node. The data transmission is not limited in this embodiment of the present application.

It should be noted that the first rule mentioned in the embodiment of the present application can be understood as a condition that triggers a node to switch from a receiving state to a transmitting state, and/or a condition that changes from a transmitting state to a receiving state.

It should be noted that the first resource allocated to the first node mentioned in the embodiment of the present application may be understood as a resource used by the first node to receive/transmit its own data (ie, an example of the first data); The second resource allocated to the second node mentioned in the embodiment of the present application can be understood as a resource used by the second node to receive/transmit its own data (ie, an example of the second data). The first resource may also serve as a cooperative resource of the second node, where the second node receives/transmits the first data, or receives/transmits collaboration data other than the self data (ie, data of other nodes). Similarly, the second resource may also serve as a cooperative resource of the first node, for the first node to receive/send the second data, or to receive/transmit collaborative data other than the own data (ie, data of other nodes).

Optionally, a Radio Resource Control (RRC) semi-static message, a Media Access Control (MAC) message, a user level of a physical layer, or a common control information (such as an L1 message or a Common L1) may be used. Message), configure common resource parameters. The common resource parameter may include at least one of the following: time-frequency resource, rate matching and mapping mode, redundancy (RV) version, scrambling code, modulation mode, frame format, frequency hopping pattern, precoding (Precoding) ) Matrix, Hybrid Automatic Repeat ReQuest (HARQ) process, Reference Signal (RS) sequence, Orthogonal Cover Code (OCC) sequence, Non-orthogonal multiple access (Non) - Orthogonal Multiple Access (NOMA) Sequence, Waveform, and Subsequence Control System (SCS).

Here, the above-mentioned contents that may be included in the common resource parameters are first briefly explained.

The time-frequency resource, the rate matching, the RE mapping mode, the scrambling code, and the modulation mode are the most basic scheduling information, and the overhead of the dedicated L1 scheduling signaling can be eliminated by the semi-static configuration. A time-frequency resource for transmitting data is configured for the master node and the child node, and the time-frequency resource includes a time domain resource and a frequency domain resource.

The cooperative behavior, that is, for a group of child nodes, cooperatively participates in data transmission of at least one target child node, or jointly receives data sent by at least one target child node. Collaborative behavior includes the behavior of each target child node cooperating with other child nodes to receive and/or transmit signals, as well as the behavior of receiving and/or transmitting frame format conversions.

The frame format includes a sending frame, a receiving frame, a sending dominant frame, and a listening dominant frame. When configuring common resource parameters, the default initial frame structure form will be configured, and subsequent changes will be made dynamically according to the collaborative behavior.

The configuration of the RV version, the hopping pattern, and the Precoding matrix can enable the Slave coding diversity, channel diversity, frequency domain diversity, and multiple-input multiple-output (MIMO) diversity to further improve the receiving performance. .

The HARQ process can be configured to configure the HARQ process with different receiving data and sending data for each sub-node, or configure the same HARQ process.

The RS sequence and the OCC sequence define sequence characteristics of various RS sequences, such as a channel-state information reference signal (CSI-RS) and a demodulation reference signal (DM-RS). Phase-tracking reference signals (PT-RS), TRS, etc. RS can coexist with data in a rate matching manner, or it can directly punch data.

The NOMA sequence defines that multiple child nodes can share the same or part of time-frequency resources in an OCC orthogonal manner or a NOMA non-orthogonal multiple access manner, thereby increasing the number of access users.

The waveform may be Orthogonal Frequency Division Multiplexing (OFDM), Single-Carrier Frequency-Division Multiple Access (SC-FDM), or the like. The SCS can correspond to different subcarrier widths, such as 15 kHz/30 kHz/60 kHz.

It should be noted that the first configuration mentioned in the embodiment of the present application may be understood as a configuration related to resources for transmitting and receiving self data and/or cooperation data. The second configuration mentioned in the embodiment of the present application can be understood as a configuration related to a frame format, a condition of a frame format conversion, an opportunity, a cooperative behavior, and the like. The third configuration and the fourth configuration mentioned in the embodiments of the present application can be understood as time information of a frame format of a node in a certain state, or time information related to a frame format conversion. In this embodiment, the time information may include at least one of the following: a starting position of the time period, a duration of the time period, a time domain pattern of the time period, and a conversion from the receiving state (transmission state) to the transmitting state (reception state). Time interval, time unit type, etc. It should be understood that the first configuration, the second configuration, the third configuration, and the fourth configuration may be included in the common resource parameters described above. In addition, the first configuration, the second configuration, the third configuration, and the fourth configuration may be separately sent to each node, or may be included in one message and sent to each node.

It should also be noted that the first node can receive data and the first node can also send data. The embodiments of the present application are not limited to uplink or downlink transmission or SideLink transmission or Device-to-Device (D2D) transmission.

The first data can be understood as: data of the first node; or, the first data can be understood as: the destination node of the first data is the first child node. That is, the first data may be data corresponding to the first child node sent by the master node. The first frequency band may be a resource used by the first child node to receive its own data. The first node receives the second data through the second frequency band, and the destination node of the second data is the second node. That is, the second data may be data corresponding to the second child node sent by the master node. In other words, the first child node can receive data corresponding to other child nodes through the second frequency band, and can also cooperatively forward the data.

The first rule can be understood as: triggering the condition that the first node changes the sending and receiving state.

In a first possible manner, if the first data is successfully received or decoded correctly, the second data is sent. It can be understood that the first node changes the transceiving state according to the decoding condition of its own data. For example, if the reception is successful or the decoding is correct, it is converted from the receiving state to the transmitting state.

In a second possible manner, if the first feedback information indicating that the second data reception fails is received, the second data is sent. It can be understood that the transceiving state is changed according to the decoding status of the respective data by other nodes. For example, when other nodes have correctly received the respective data, the first node does not need to cooperate to forward the cooperation data; for example, when other nodes do not all correctly receive the respective data, or all of them do not correctly receive the respective data, the first The node can convert from the receiving state to the transmitting state and cooperatively forward the cooperative data to improve the probability that the cooperative node receives the respective data.

In a third possible manner, if the current time period is the second time period, the second data is sent.

In a fourth possible manner, if the urgency of the second data meets an emergency condition, the second data is sent. The emergency condition may be preset or determined on a case-by-case basis. For example, the emergency condition may include: when the transmitted data includes warning information (for example, commercial mobile alert system (CMAS) information), determining that the urgency of the data meets the emergency condition; or the emergency condition may include: When the data is data with high latency requirements, it is determined that the urgency of the data meets the emergency condition. When the second data is urgent, the first node can cooperatively forward the second data.

It should be noted that the first rule mentioned in the present application includes one or more items, and it can be understood that the first rule may include one or more of all possible ways listed. The four possible ways listed above are exemplified for example.

Specifically, the first rule may include any one of the possible modes listed above, for example, may include the first possible manner, the second possible manner, the third possible manner, or the fourth possibility The way.

Alternatively, the first rule may include some of the possible ways listed above. For example, the first rule may include: a first possible way and a second possible way, or a first possible way and a third possible way, or the first possible way and the fourth Possible way, or, the second possible way and the third possible way, or the second possible way and the fourth possible way, or the third possible way and the fourth possible the way. As another example, the first rule may include: a first possible mode, a second possible mode, and a third possible mode, or the first possible mode, the second possible mode, and the fourth Possible way, or, the first possible way, the third possible way, and the fourth possible way, or the second possible way, the third possible way, and the fourth possibility The way.

Alternatively, the first rule may include all of the possible ways listed above, that is, the first rule may include: a first possible way, a second possible way, a third possible way, and a fourth possibility The way.

It should be understood that the above-mentioned "first", "second", "third", and "fourth" are only for distinguishing different objects, and do not constitute any limitation to the present application. For example, the first possible way and the second possible way are merely to indicate two different possible ways.

The following is a detailed description of the specific content that may be included in the common resource parameters from the perspective of interaction.

First, a process in which a master (that is, an example of a master node) transmits data to a slave (that is, an example of a child node or a first node) will be described as an example. In the embodiment of the present application, for the sake of brevity, the Master is simply referred to as M, and the Slave is simply referred to as S, and S1, S2, and S3 respectively represent different child nodes.

The data transmitted between the Master and the Slave includes at least the following two methods.

Mode 1

Joint coding. In the embodiment of the present application, the joint coding may refer to sending and receiving command data of all or a part of the child nodes as a data packet, where the data packet may be jointly coded by command data of all or a part of the child nodes. It can also be just a joint rate match. The Joint Coded Cyclic Redundancy Check (CRC) can be performed only on the overall data, or each sub-node can still maintain its own independent CRC. The coding may be a variety of feasible coding modes such as a Low Density Parity Check Code (LDPC), a Turbo, and a Polarization.

FIG. 7 shows a schematic diagram of joint coding when a primary node transmits data to a child node. In Fig. 7, there is one master node M and three child nodes S1, S2, S3. One cycle time is 1ms, and there are eight time units in one cycle time. In the embodiment of the present application, it is assumed that the data transmitted between M and S includes: command data (command, C) and feedback data (denoted as R). That is, the self data of S1 (that is, the data corresponding to S1) is recorded as C1, R1, and S2's own data (that is, the data corresponding to S2) is recorded as C2, R2, and S3's own data (that is, the data corresponding to S3). For C3, R3.

It should be understood that the first data may include C1 and/or R1 and the second data may include C2 and/or R2. Among them, R1 can also be called feedback data of C1, and R2 can also be called feedback data of C2.

It should be understood that the time unit in the embodiment of the present application may also be referred to as a duration or a time interval or a time period or a time. That is, one cycle time includes a plurality of durations or time intervals or time periods or moments.

For M, M is always in the transmission state in one cycle time, that is, the data packets including C1, C2, and C3 are always sent. Optionally, the data packet may also include feedback data R1, R2, and R3.

For S1, S1 receives the packet in the first time unit. If S1 decodes C1 correctly, then S1 may no longer receive the data packet in a later time unit, but cooperatively forward the data packet.

For S2, S2 receives the packet in the first time unit, but the decoding fails, then S2 still receives the packet in the second time unit. If S2 is correctly decoded for C2 in the second time unit, then S2 does not receive the data packet in the third time unit, but cooperatively forwards the data packet.

For S3, in the first two time units, S3 receives the data packet, and the decoding fails, then S3 still receives the data packet in the third time unit. If, in the third time unit, S3 correctly decodes the received C3, then in the following time unit, S3 does not need to receive the data packet again, but cooperatively transmits the data packet.

It should be noted that, in the embodiment of the present application, T is used to indicate Transmit, and R is used to indicate reception. After receiving the data of the own node, and the decoding is correct, the child node can no longer receive its own data, but cooperatively send the data of other child nodes.

Mode 2

Non-joint coding. In the embodiment of the present application, the non-co-coding may refer to different resources configured by different sub-nodes, for example, different time-frequency resources, different orthogonal resources, different NOMA resources, and the like. Alternatively, for decoding the correct child node S, it is no longer possible to receive/send its own data, but only the collaborative data (ie, the data of other child nodes).

Figure 8 shows a schematic diagram of non-co-encoding when the primary node sends data to the child node. In Fig. 8, there is one master node M and three child nodes S1, S2, S3. One cycle time is 1ms, and there are eight time units in one cycle time.

For M, M is always in the transmitting state in one cycle time, that is, data C1, C2, C3 is always transmitted. Alternatively, M can also send feedback data R1, R2, R3.

For S1, S1 receives C1, C2, C3 from M in the first time unit. If S1 decodes C1 correctly, then S1 may no longer receive data C1 in subsequent time units, but cooperatively forward data of other child nodes, namely C2 and C3.

For S2, S2 receives C1, C2, C3 from M in the first time unit. Assuming that S2 fails to decode C2, then S2 still receives data C2 in the second time unit. Specifically, S2 receives C1, C2, C3 from M, and C2 and C3 from S1 in the second time unit. If S2 is correctly decoded in C2 in the second time unit, S2 does not receive data in the third time unit, but cooperatively forwards data of other child nodes, that is, S2 cooperatively forwards C1 and C3.

For S3, S3 receives C1, C2, C3 from M in the first time unit, but fails to decode C3, then S3 still receives data C3 in the second time unit. Specifically, S3 receives C1, C2, C3 from M, and C2 and C3 from S1 in the second time unit. If S3 is still in error in C3 decoding in the second time unit, then S3 still receives data C3 in the third time unit. Specifically, S3 receives C1, C2, C3 from M, and C2 and C3 from S1, and C1 and C3 from S2 in the third time unit. If S3 is correctly decoded in C3 in the third time unit, S3 no longer receives the data, but cooperatively forwards the data of other child nodes, namely C1 and C2.

It should be noted that the above two modes are merely exemplary descriptions, and the embodiments of the present application are not limited thereto. For example, the child nodes may be grouped first, the data corresponding to one group of nodes is jointly coded, and the data corresponding to the other group of nodes is non-joined.

As described above, in the embodiment of the present application, when data is transmitted between the primary node and the child node, common resource parameters are pre-configured, that is, semi-statically configured common resource parameters.

Specifically, the common resource parameters are semi-statically configured for M, S1, S2, and S3. For S1, the common resource may include the resource of S1, the resource of S2, and the resource of S3. The resource of S1 refers to the resource used when transmitting S1 own data; the resource of S2 refers to the resource used when S1 transmits the data corresponding to S2 (that is, the data corresponding to S2); the resource of S3 refers to , S1 uses the resources used when transmitting data corresponding to S3. Similarly, for S2, the common resources include the resources of S1, the resources of S2, and the resources of S3. Similarly, for S3, the common resources include the resources of S1, the resources of S2, and the resources of S3. Similarly, for M, the common resources include the resources of S1, the resources of S2, and the resources of S3. The details will be explained next.

Time-frequency resources are semi-statically configured for M, S1, S2, and S3.

For S1, S1 receives the time-frequency resource sizes F1 and T of its own data each time, and the time-frequency resource sizes F2/F3 and T that are cooperatively transmitted and received. Or, the time-frequency resource size of the S1 receiving the data itself is F1 and T, the time-frequency resource size of the cooperative transmitting and receiving S2 is F2 and T, and the time-frequency resource size of the cooperative transmitting and receiving S3 is F3 and T.

For S2, S2 receives the time-frequency resource sizes F2 and T of its own data each time, and the time-frequency resource sizes F1/F3 and T that are cooperatively transmitted and received. Alternatively, the time-frequency resource size of the S2 receiving its own data is F2 and T, the time-frequency resource size of the cooperative transmitting and receiving S1 is F1 and T, and the time-frequency resource size of the cooperative transmitting and receiving S3 is F3 and T.

For S3, S3 receives the time-frequency resource sizes F3 and T of its own data each time, and the time-frequency resource sizes F2/F1 and T that are cooperatively transmitted and received. Or, the time-frequency resource size of the S3 receiving the data itself is F3 and T, the time-frequency resource size of the cooperative transmitting and receiving S2 is F2 and T, and the time-frequency resource size of the cooperative transmitting and receiving S1 is F1 and T.

For M, the M transmits and receives the time-frequency resource sizes F1 and T of the data corresponding to S1, and transmits and receives the time-frequency resource sizes F2 and T of the data corresponding to S2, and transmits and receives the time-frequency resource sizes F3 and T of the data corresponding to S3. Alternatively, the M transmits and receives the data corresponding to S1, the data corresponding to S2, and the data corresponding to S3, and the time-frequency resources may all be the same or partially the same.

FIG. 9 illustrates the process of data transmission in the first four time units by M, S1, and S2. In the embodiment of Fig. 9, the C1 and C2 non-coupling coding will be described as an example.

Optionally, the first node receives a first configuration, where the first configuration is used to indicate the first resource and the second resource. That is, the common resource parameters (ie, an example of the first configuration) are previously configured for M, S1, and S2. For S1, the configured common resource parameters include the resources of S1 and the resources of S2, and vice versa for S2 and M. That is, the first configuration can be understood as a resource for instructing each node to send and receive its own data and collaboration data.

Optionally, configure time-frequency resources. Each time S1 receives the time-frequency resource sizes F1 and T of its own data, and cooperatively transmits and receives time-frequency resource sizes F2 and T. Each time S2 receives the time-frequency resource sizes F2 and T of its own data, the time-frequency resource sizes F1 and T that are cooperatively transmitted and received.

It should be noted that, in the embodiment of the present application, each user in the configured resource (that is, an instance of the Slave) may have more than one resource, for example, the frequency domain resource of the S2 cooperative receiving S1 is F1, but the frequency of the S1 is cooperatively transmitted. The domain resource is F3, and as long as these resources are configured to be public, there is no comprehension bias.

Specifically, in the embodiment of FIG. 9, during the T1 period, M transmits data C1, C2 on different frequency domain resources F1 and F2. The S1 public resource F1 receives C1 and the public resource F2 receives C2. S2 receives C1 on the common resource F1 and C2 on the common resource F2.

Optionally, the first node receives a fourth configuration, where the fourth configuration is used to indicate the first time period.

Optionally, the fourth configuration indicates the first time period by indicating one or more of: a starting position of the first time period, a duration of the first time period, the first The time domain pattern of the time period, and the time unit type occupied by the first time period.

Specifically, the information of the time period in which the data is received may be configured in advance for the child node. For example, the child node may be instructed to receive data at a certain starting location and/or for a predetermined period of time.

Optionally, the first node receives a second configuration, where the second configuration is used to indicate the first rule. That is, the semi-static configuration cooperation behavior (ie, an example of the second configuration). Collaboration behavior can include changes in frame format, collaborative reception and/or collaborative delivery, and the like. The frame format includes two states, a receiving state and a transmitting state. In the embodiment of the present application, at least one of the following collaborative actions is included.

When the master node is in the transmit state, it sends data to the child node according to the configured common resource parameters.

When receiving the state, the child node receives its own data co-sent from the master node and/or other child nodes according to the configured common resource parameters, and cooperatively receives the master node and/or other children on other common resources. The data corresponding to other child nodes sent by the node.

When the child node is in the transmit state, it does not send data on its own resources according to the configured common resource parameters, and cooperatively transmits command data of other child nodes on other common resources. Optionally, the power of the non-transmitted resource may be allocated to the sending resource according to a certain rule.

It should be understood that the foregoing is only an exemplary description, and the embodiment of the present application is not limited thereto. For example, the first node receives the third configuration, and the third configuration is used to indicate the second time period. That is, for the master node, it can be configured to be in the transmit state at the beginning, and after a predetermined time (ie, an example of the second time period), it is converted to the receive state. The second time period of the indication may be at least one of: a starting position of the second time period, a duration of the second time period, a time domain pattern of the second time period, the first a time domain interval between the second time period and the first time period, and a time unit type occupied by the second time period).

Specifically, in the embodiment in FIG. 9, the initial configuration of the frame format of M is a transmission state, and the frame format of S is initially configured as a reception state.

Optionally, it is determined whether to convert the state of the frame format according to the decoding result of the child node to the self data.

Specifically, in the embodiment of FIG. 9, for S1, it is assumed that S1 decodes C1 correctly during the T1 period, and then, in the T2 period, S1 is switched from the receiving state to the transmitting state. After S1 is switched from the receiving state to the transmitting state, in the following period, it is possible to not receive its own data on F1, but to jointly transmit C2 on F2. For S2, it is assumed that in the T1 period, S2 decodes the C2 error and remains in the receive state during the T2 period. And, S2 receives data from M and S1 in the T2 period.

Alternatively, when the child node decodes its own data correctly, the child node determines the state of the frame format to be converted at a given time. Wherein, the given time can be after multiple Ts.

Alternatively, when S1 determines that the urgency of C2 satisfies the preset condition, C2 is transmitted to S2 through F2. Specifically, the child node may be forwarded from the receiving state to the transmitting state according to the importance degree of the data corresponding to the other child nodes, that is, the data corresponding to the other child nodes are cooperatively transmitted.

During the T2 period, M continues to send C1 and C2. S1 terminates receiving/transmitting data on F1 and cooperatively transmits C2 on F2. S2 receives C2 from M and S1 transmissions on F2. Assuming S2 decodes C2 correctly, S2 transitions from the receive state to the transmit state during the T3 period.

Optionally, S1 may directly forward the C2 data that is co-sent, or may decode, re-encode, and forward.

During the T3 period, M continues to send C1 and C2. S1 continues to send C2 on F2. S2 continues to send C1 on F1.

During the T4 period, M continues to send C1 and C2. S1 continues to send C2 on F2. S2 continues to send C1 on F1.

It should be noted that, after S1 or S2 decodes its own data correctly, it can continue to receive data from M or other child nodes, and cooperatively forward the received data.

Optionally, the configured common resource parameters may further include: a rate matching and mapping mode, an RV version, and a modulation mode.

Specifically, a resource mapping manner of sending data of each child node on respective time-frequency resources is determined. For example, the rate matching method is to completely fill the data of any transport block size within a given time-frequency resource. For example, the mapping mode may be first frequency domain re-time domain mapping, or first time domain re-frequency domain mapping.

Optionally, the configured common resource parameters further include: other basic parameters, such as a HARQ process, an RS sequence, a waveform, a subcarrier width, and the like.

Optionally, after receiving the data sent by the M, the S feedbacks to the M whether it is correctly decoded. The embodiment of the present application is described by taking the form that the feedback signal is ACK/NACK as an example. It should be understood that the form of the feedback signal in the embodiment of the present application is not limited to being ACK/NACK. FIG. 10 is a schematic diagram of a method of transmitting data according to another embodiment of the present application.

Optionally, the first configuration is further used to indicate the third resource. That is, when the common resource is configured, the common control channel resource parameter (that is, an example of the third resource) may be additionally configured, including the time-frequency resource, sequence, and the like of the S-feedback ACK/NACK.

Optionally, the target child node sends ACK information/NACK information to the other child nodes and/or the primary node according to the decoding result of the target child node to the own data, where the ACK information/NACK information is used for the other child nodes and / or whether the master node continues to send data of the target child node.

Specifically, after the child node is correctly decoded, the child node feeds back ACK information on a given time-frequency resource, and the ACK information is received by the master node and the child node that is cooperatively transmitted, thereby terminating the sending of the master node and the cooperatively sent child node. The command data corresponding to the child node. Thereby unnecessary transmission can be avoided, further saving resources.

As shown in FIG. 10, S1 decodes C1 correctly, thereby transmitting ACK information, and M and S2 receive the ACK information. In the following time unit, M and S2 do not need to send C1 again.

Optionally, after the sub-node fails to decode, the NACK information is fed back at a given moment and the resource, and the NACK information is received by the primary node and the cooperatively sent child node, thereby triggering the primary node and the cooperatively sent child node to send the target. The command data of the child node, the number of consecutive transmissions triggered is K1, where K1 ≥ 1.

Alternatively, the feedback message can trigger a state change in the frame format. That is, according to the decoding result of the target child node to its own data, the target child node sends ACK information/NACK information to other child nodes and/or the master node, and the ACK information/NACK information is used for the other child nodes and/or The master node determines the state of the frame format.

Optionally, after the child node is correctly decoded, the ACK information is fed back at a given time and resource, and the ACK information is received by the cooperatively sent child node, and the cooperative child node is triggered to be converted from the transmitting state to the receiving state.

Optionally, after the sub-node fails to decode, the NACK information is fed back at a given moment and the resource, and the NACK information is received by the cooperatively sent child node, and the cooperative child node is triggered to be converted from the receiving state to the transmitting state.

Optionally, the feedback ACK/NACK information may carry indication information at the same time, indicating which cooperative child nodes and/or the master node perform cooperative transmission or no cooperative transmission. Optionally, information about the corresponding transmit power, time-frequency resources, and the like may also be indicated.

FIG. 11 illustrates an example of the process of data transmission in the first four time units by M, S1, and S2, and the process is specifically described. In the embodiment of Fig. 11, the joint coding is performed using C1 and C2 data as an example.

The common resource parameters are configured in advance for M, S1, and S2. For S1, the configured common resource parameters include the resources of S1 and the resources of S2, and vice versa for S2 and M.

Optionally, time-frequency resources are configured for M, S1, and S2.

One possible way is to configure the same common resource parameters for all the child nodes, such as configuring the frequency domain F1+F2 for S1 and S2, and the time domain T as the time-frequency resource of the jointly encoded data packet of one transmission. Alternatively, another possible way is to group all the child nodes, and each group of the nodes performs joint coding, for example, configuring the frequency domain F1 for S1/S3, and the time domain T as the time-frequency of the jointly encoded data packet of one transmission. Resource; configure frequency domain F2 for S2/S4, time domain T as the time-frequency resource of the jointly encoded data packet of one transmission.

It should be noted that, in the embodiment of the present application, the resources of each user in the configured resources may be more than one, for example, the frequency domain resource of the S2 cooperative receiving S1 is F1, but the frequency domain resource of the cooperative sending S1 is F3, as long as these If resources are configured to be public, there will be no comprehension bias.

Specifically, in the embodiment of FIG. 11, during the T1 period, M transmits joint encoded data C1 & C2 on the common resource F1+F2, and the child nodes S1 and S2 receive C1&C2 on the configured common resources F1 and F2.

It should be understood that in the embodiment of the present application, C1 & C2 indicates that C1 and C2 are transmitted in the form of data packets.

Optionally, the configured resources may also include configuring a collaboration behavior. Collaborative behavior includes changes in frame format, collaborative reception, and collaborative delivery. The configured collaborative behavior includes at least one of the following.

The master node continuously sends the jointly encoded data.

After the child node is decoded correctly, the frame format is switched from the receiving state to the transmitting state at a given time. The given time may refer to K2 ≥ 0 after K2 periods.

When the child node receives the state, it receives the joint encoded data packet according to the configured common resource parameters, and decodes the data corresponding to itself. Alternatively, the child node can simultaneously decode data of other child nodes.

When the child node is in the transmit state, it sends a joint encoded data packet according to the configured common resource parameters. The child nodes can be forwarded directly, or they can be decoded and forwarded.

In the embodiment of FIG. 11, the initial configuration of the frame format of M is the transmission state, and the frame format of S is initially configured as the reception state.

Optionally, it is determined whether to convert the state of the frame format according to the decoding result of the child node to the self data.

Specifically, in the embodiment of FIG. 11, assuming that S1 decodes C1 correctly, then in the T2 period, S1 transitions from the receive state to the transmit state. S2 decodes the C2 error and remains in the receive state during the T2 period.

During the T2 period, M continues to send C1&C2. S1 terminates receiving/transmitting data on F1 and cooperatively transmits C1&C2 on F2. S2 receives C1&C2 from M and S1 transmissions on F2. Assuming S2 decodes C2 correctly, S2 transitions from the receive state to the transmit state during the T3 period.

Optionally, S1 may directly forward the C1&C2 data sent by the cooperative, and may also decode and re-encode and forward the data.

During the T3 period, M continues to send C1&C2. S1 continues to send C1&C2 on F2. S2 continues to send C1&C2 on F1.

During the T4 period, M continues to send C1&C2. S1 continues to send C1&C2 on F2. S2 continues to send C1&C2 on F1.

Optionally, the configured common resource parameters may further include: a rate matching and mapping mode, an RV version, and a modulation mode.

Specifically, a resource mapping manner of sending data of each child node on respective time-frequency resources is determined. For example, the rate matching method is to completely fill the data of any transport block size within a given time-frequency resource. For example, the mapping mode may be first frequency domain re-time domain mapping, or first time domain re-frequency domain mapping.

Optionally, the configured common resource parameters further include: other basic parameters, such as a HARQ process, an RS sequence, a waveform, a subcarrier width, and the like.

Optionally, after receiving the data sent by the M, the S feeds back ACK/NACK to the M. FIG. 12 is a schematic diagram of a method of transmitting data according to another embodiment of the present application.

When configuring a common resource, the common control channel resource parameters may be additionally configured, including the time-frequency resource, sequence, and the like of the S-feedback ACK/NACK.

Optionally, the target child node sends ACK information/NACK information to the other child nodes and/or the primary node according to the decoding result of the target child node to the own data, where the ACK information/NACK information is used for the other child nodes and / or whether the master node continues to send data of the target child node.

After the child node is correctly decoded, the child node feeds back ACK information at a given time and resource, and the ACK information is received by the master node and the child node that is cooperatively transmitted, thereby terminating the master node and the cooperative child node to send the corresponding node. data. Thereby unnecessary transmission can be avoided, further saving resources.

Optionally, the target child node sends ACK information/NACK information to the other child nodes and/or the primary node according to the decoding result of the target child node to the own data, where the ACK information/NACK information is used for the other child nodes and / or the master node determines the state of the frame format.

The embodiment shown in FIG. 11 is similar to the embodiment shown in FIG. 10, and is not described here for brevity.

It should be noted that each of the foregoing configuration information may be included in one information, for example, in a configuration information, indicating its own resources, cooperation resources, feedback resources, conditions for triggering frame format conversion, conditions for triggering transmission and reception state transition, Time information of the transceiver state, etc.

7 to 11 are examples in which the master node transmits data to the child nodes as an example. Next, an example will be described in which data is transmitted from a child node to a master node in conjunction with FIG. 12 to FIG.

The first node receives the second data of the second node on the second resource allocated to the second node in the first time period;

Transmitting, by the first node, the first data of the first node and the sending the second resource on the first resource allocated to the first node according to the first rule Two data;

The first rule includes one or more of the following:

Sending the second data if the second data is successfully received or decoded correctly;

If the data of the M nodes is successfully received, the M meets the threshold, and the second data is sent, where the M nodes include the second node, where M is a positive integer;

Sending the second data if receiving the first feedback information indicating that the second data reception fails;

Sending the second data if the current time period is the second time period;

And transmitting the second data if the urgency of the second data meets an emergency condition.

It is assumed that the child node sends feedback data (Response, denoted as R) to the master node, R1 is feedback data corresponding to S1, R2 is feedback data corresponding to S2, and R3 is feedback data corresponding to S3. The feedback data may be carried in the data channel or in the control channel, which is not limited in this embodiment of the present application. In addition, the child nodes can also receive data sent by other cooperative child nodes.

FIG. 12 shows a schematic diagram of a child node transmitting feedback data to a master node.

The common resource parameters (ie, an example of the first configuration) and the cooperative behavior (ie, an example of the second configuration) are semi-statically configured for the primary node and a set of child nodes. Optionally, the common resource includes resources of the target child node, and resources of some or all of the cooperative child nodes. The resources include at least one of the following: time-frequency resources, rate matching and mapping mode, RV version, modulation mode, frame format, frequency hopping pattern, HARQ process, RS sequence, OCC sequence, NOMA sequence, waveform, and SCS.

Collaborative behavior can be understood as an example of the first rule. Collaborative behavior includes the behavior of each target child node cooperating with other child nodes to receive and transmit data or signals, and the behavior of receiving and transmitting frame format conversions. Optionally, the collaborative behavior includes at least one of the following.

During a cycle time, the master node continuously listens in a semi-statically configured repetition or cycle time unit, and correctly receives the target feedback message to indicate each child node, and initially configures the child node according to a certain cooperation rule.

Each child node sends its own feedback message according to a certain rule. When the master node receives the feedback message of the target child node, it considers successful reception.

When the target child node sends a message to the master node, it also sends the message to other parts of the child node in the group.

The child node in the initial configuration of the child node listens to the child node in the sending state, and sends the self-feedback message and the received messages of other child nodes according to certain rules at the time of sending the message, and implicitly indicates The number of child nodes the message contains (for example, by the size of the selected resource block). For example, for S2, S2 sends R1 and R2.

After the child node self-feedback message is received by the master node, it will cooperatively send messages of other child nodes that are not received by the master node at its own transmission opportunity. For example, for S3, since the master node feedback R3 receives correctly, S3 only needs to send R1 and R2.

It should be noted that, when the cooperative child node is in the auxiliary transmission, the message sent may be jointly coded or non-co-coded.

It should also be noted that when each child node sends a message, reasonable power control can be performed according to the coding type, and energy efficiency is prioritized.

As mentioned before, the transmitted data can be either non-co-coded or joint coded. Next, the two cases in the interaction process in which the child node transmits data to the master node will be respectively described with reference to FIGS. 13 and 14.

Figure 13 is the case of non-coupling coding. FIG. 13 illustrates the process of data transmission in the first four time units by M, S1, S2, and S3. In the embodiment of Fig. 13, the non-coupling coding of R1, R2, and R3 is taken as an example for description.

The common resource parameter is semi-statically configured for the master node M and the group of child nodes S1, S2, and S3. For S1, the common resource includes the resource of S1, the resource of S2, and the resource of S3, and vice versa for S2, S3, and M. .

Optionally, configure time-frequency resources. Each time S1 sends the time-frequency resource sizes F1 and T of its own data, the cooperative transmission and reception time-frequency resource sizes are F2/F3 and T. S2 and S3 are similar.

It should be noted that, in the embodiment of the present application, the resources of each user in the common resource may be more than one, for example, the frequency domain resource of the S2 cooperative receiving S1 is F1, and the frequency domain resource of the cooperative sending S1 is F4, as long as the resource configuration is configured. For the public, there will be no understanding bias.

Specifically, the diagram (1) in FIG. 13 is taken as an example. For S1, during the T1 period, S1 sends R1 on F1, and M, S2, S3 all receive R1 on F1. During the T2 period, S1 receives R1 on F1 and R2 on F2. During the T3 period, S1 receives R1 on F1, R2 on F2, and R3 on F3. During the T4 period, S1 sends R1 on F1, R2 on F2, and R3 on F3.

Optionally, semi-statically configure collaborative behavior. Collaboration behavior can include changes in frame format, collaborative reception and/or collaborative delivery, and the like. In the embodiment of the present application, at least one of the following collaborative actions is included.

When the child node receives the state, it cooperates to receive feedback data sent by other child nodes on other common resources according to the configured common resource parameters.

When the child node is in the transmitting state, it sends its own feedback data on its own resources according to the configured common resource parameters, and cooperatively transmits the feedback data of other child nodes on other common resources. Optionally, the power of the non-transmitted resource may be allocated to the sending resource according to a certain rule.

For the primary node, the primary node is always configured to receive, that is, the primary node continues to receive R1, R2, and R3. The child node is configured to at least one of two phases of a feedback data interaction phase and a feedback data collaborative delivery phase. Next, the configuration of these two phases will be specifically described.

It should be understood that the foregoing is only an exemplary description, and the embodiment of the present application is not limited thereto. For example, for the primary node, it may also be configured as a receiving state at the beginning, and after a predetermined time, converted to a transmitting state.

First, the feedback data interaction phase frame format

The feedback data interaction phase frame format includes at least one of the following configurations.

1. Duration K3 T, where K3 ≥ 0 (K3 = 0 means no interaction phase is configured). That is, the child node interacts with other child nodes to feed back data in K3 time units.

It should be noted that the interaction phase K3 of all the child nodes may be configured the same or differently configured.

2. Different sub-nodes are configured with different transceiving patterns to ensure as many data interaction opportunities as possible, such as comb-tooth transceiver patterns with different sub-node configurations that do not overlap. As shown in the diagram (1) in Fig. 13, in the period T1, S1 is in the transmitting state, and S2 and S3 are in the receiving state. During the T2 period, S2 is in the transmit state and S1 and S3 are in the receive state. During the T3 period, S3 is in the transmit state and S1 and S2 are in the receive state.

3. Different sub-nodes are configured with different transceiving patterns to ensure as many data interaction opportunities as possible. For example, configuring a specific sub-node (for example, a sub-node with better channel quality of other sub-nodes) is initially received, while other sub-nodes The node is initially in the transmit state, which in turn ensures sufficient data interaction in a shorter time. As shown in the diagram (2) in FIG. 13, it is assumed that the channel quality between S1 and S2 and S3 is good, the configuration S1 is initially in the receiving state, and S2 and S3 are initially in the transmitting state. That is, in the T1 period, S1 is the receiving state, and S2 and S3 are the transmitting states.

Second, feedback data collaborative transmission phase frame format

The feedback data cooperative transmission phase frame format includes at least one of the following configurations.

1. The duration is K4 T, where K4 ≥ 0 (K4 = 0 means no coordination phase is configured). That is, the child nodes cooperatively transmit data in K4 time units.

It should be noted that the cooperative transmission phase K4 of all the child nodes may be configured the same or different configurations.

2. In the collaboration phase, different sub-nodes can still be configured with different transceiving patterns to ensure that there is still an opportunity for interactive feedback data during the cooperation phase. In this case, the frame format is converted to a semi-static configuration.

3. In the cooperation phase, different child nodes can also autonomously perform frame format conversion according to the decoding situation of the feedback data of other child nodes.

Optionally, the frame format conversion is performed according to the pattern of the configured transceiving frame format.

Optionally, the target child node receives M feedback data of the M child nodes, and the target child node determines whether to convert the state of the frame format according to the information of the M feedback data.

Specifically, the feedback data sent by the other child nodes is decoded, and the frame format conversion is performed according to the decoding result and a certain criterion. One possible way is that the criterion can be the number of correctly decoded feedback data. For example, if the correctly decoded feedback data reaches N, then frame format conversion is performed, N≥1. Wherein, when N=1, it means that as long as there is a correct decoding, the frame format conversion is performed. Or, N is the number of child nodes, indicating that all translated pairs can be converted. Or determining whether to perform frame format conversion according to channel quality, routing status, and historical information of feedback data decoding quality between different child nodes.

Next, it will be specifically described with reference to the diagram (2) in FIG.

During the T1 period of the interaction phase, according to the configured frame format pattern, the child nodes S2 and S3 respectively transmit R2 and R3 on the configured common resources F2 and F3; M and S1 receive R2 and R3 on the configured common resources. Suppose S1 correctly decodes R2 and R3.

During the T2 period of the interaction phase, according to the configured frame format pattern, S1 transmits its own R1 on the configured common resource, and cooperatively transmits R2 and R3; M, S2, and S3 receive R1, R2, and R3 on the common resource. Optionally, S2 and S3 determine whether the T3 period is converted to a transmission state according to a decoding situation of the feedback data transmitted cooperatively; or forcibly convert to a transmission state according to the configured cooperation phase frame format pattern.

During the T3 period of the collaboration phase, S1, S2, and S3 cooperate to transmit R1, R2, and R3.

During the T4 period of the collaboration phase, S1, S2, and S3 cooperate to transmit R1, R2, and R3.

Optionally, the configured common resource parameters may further include: a rate matching and mapping mode, an RV version, and a modulation mode.

Specifically, the resource mapping manner of the sending data of each child node on the respective time-frequency resources is determined. For example, the rate matching mode is that the data of any transport block size is completely filled in a given time-frequency resource, for example, the mapping mode may be first frequency. The domain re-time domain mapping, or the first-time domain re-frequency domain mapping, etc., for example, the RV version of each transmission may be the same or different, for example, the modulation mode of each transmission may be the same or different.

Optionally, the configured common resource parameters may further include: a HARQ process, an RS sequence, a waveform, a subcarrier width, and the like.

As another embodiment, the master node M can feed back ACK/NACK. The details will be explained next.

The common resource parameters are semi-statically configured for the master node M and the group of child nodes S1, S2, and S3, and the common control channel resource parameters may be additionally configured, including the time-frequency resources and sequences of the A/N fed back by the child node.

The semi-static configuration of the cooperative behavior of the master node M and a group of child nodes S1, S2, and S3 can additionally increase the following possibilities.

In a possible manner, after the primary node decodes the feedback data of a certain child node, the ACK information is fed back at a given time and resource, and the ACK information is received by the child node and the child node that is cooperatively transmitted, thereby terminating the child. The feedback data corresponding to the node is sent on the child node and the cooperative child node.

In a possible manner, after the primary node fails to decode the feedback data of a certain child node, the NACK information is fed back at a given time and resource, and the NACK information is received by the child node and the child node that is cooperatively transmitted, thereby triggering the child. The node and the cooperative child node send feedback data of the target child node, and the number of consecutive transmissions triggered is K5 (K5 ≥ 1).

In a possible manner, after the primary node decodes the feedback data of a certain child node, the ACK information is fed back at a given time and resource, and the ACK information is received by the cooperatively sent child node, and the cooperative child node is triggered from the transmitting state. Convert to receive state.

In a possible manner, after the primary node fails to decode the feedback data of a certain child node, the NACK information is fed back at a given moment and the resource, and the NACK information is received by the cooperatively sent child node, and the cooperative child node is triggered from the receiving state. Convert to send status.

Optionally, the feedback ACK information/NACK information may carry indication information at the same time, indicating which cooperative child nodes perform cooperative transmission or no cooperative transmission. Optionally, the indication information may further indicate information such as a corresponding transmission power, a time-frequency resource, and the like.

Figure 14 is the case of joint coding. FIG. 14 takes the process of data transmission in the first 4 time units by M, S1, S2, and S3 as an example, and specifically describes the process. In the embodiment of Fig. 14, the joint coding is performed by taking R1, R2, and R3 as an example.

The common resource parameters are semi-statically configured for the master node M and a group of child nodes S1, S2, and S3.

Optionally, time-frequency resources are configured for M, S1, S2, and S3.

One possible way is to configure the same joint coded common resource parameters for all the child nodes, such as configuring the frequency domain F1+F2+F3 for S1, S2 and S3, and the time domain T as the joint coded data packet of one transmission. Frequency resources.

Or, in another possible manner, all the child nodes are grouped, and each group of the child nodes is jointly coded, for example, the frequency domain F1+F2 is configured for S1/S2, and the time domain T is used as the time-frequency of the jointly encoded data packet of one transmission. Resource; configure the frequency domain F3+F4 for S3/S4, and the time domain T is used as the time-frequency resource of the jointly encoded data packet of one transmission.

Or, in another possible manner, configuring the independently coded common resource parameters of each child node, such as the time-frequency resource size F1 and T of S1 each time sending its own data, and the cooperative transmission and reception time-frequency resource size is F2/F3 and T; S2 and S3 are similar.

Optionally, the configured resources may also include configuring a collaboration behavior. Collaborative behavior includes changes in frame format, collaborative reception and/or collaborative delivery, and the like. In the embodiment of the present application, at least one of the following collaborative actions is included.

For the primary node, the primary node can always be configured to receive state. That is, the master node continuously receives the feedback data of S1, S2, and S3.

For the child node, the child node is configured to feedback at least one of two phases of the data interaction phase and the feedback data cooperation delivery phase. Next, the configuration of these two phases will be specifically described.

First, the feedback data interaction phase frame format

The feedback data interaction phase frame format includes at least one of the following configurations.

1. The duration is K6 T, where K6≥0 (K6=0 means no interaction phase is configured).

It should be noted that the interaction phase K6 of all the child nodes may be configured the same or differently.

2. Different sub-nodes are configured with different transceiving patterns to ensure as many data interaction opportunities as possible, such as comb-tooth transceiver patterns with different sub-node configurations that do not overlap. As shown in the diagram (1) in Fig. 14, in the period T1, S1 is in the transmitting state, and S2 and S3 are in the receiving state. During the T2 period, S2 is in the transmit state and S1 and S3 are in the receive state. During the T3 period, S3 is in the transmit state and S1 and S2 are in the receive state.

3. Different sub-nodes are configured with different transceiving patterns to ensure as many data interaction opportunities as possible. For example, configuring a specific sub-node (for example, a sub-node with better channel quality of other sub-nodes) is initially received, while other sub-nodes The node is initially in the transmit state, which in turn ensures sufficient data interaction in a shorter time. As shown in the diagram (2) in FIG. 14, it is assumed that the channel quality between S1 and S2 and S3 is good, the configuration S1 is initially in the receiving state, and S2 and S3 are initially in the transmitting state. That is, in the T1 period, S1 is the receiving state, and S2 and S3 are the transmitting states.

Second, feedback data collaborative transmission phase frame format

The feedback data cooperative transmission phase frame format includes at least one of the following configurations.

1. The duration is K7 T, where K7 ≥ 0 (K7 = 0 means no coordination phase is configured).

It should be noted that the cooperative transmission phase K7 of all the child nodes may be configured the same or differently configured.

2. In the cooperation phase, different sub-nodes can still be configured with different transceiving patterns to ensure that there is still an opportunity to exchange feedback data during the cooperation phase. In this case, the frame format conversion is semi-statically configured by pattern.

3. In the cooperation phase, different child nodes can also autonomously perform frame format conversion according to the decoding situation of the feedback data of other child nodes.

Optionally, the frame format conversion is performed according to the pattern of the configured transceiving frame format.

Optionally, the feedback data sent by the other child nodes is decoded, and the frame format conversion is performed according to the decoding result and a certain criterion. One possible way is that the criterion can be the number of correctly decoded feedback data. For example, if the correctly decoded feedback data reaches N, then frame format conversion is performed, N≥1. Wherein, when N=1, it means that as long as there is a correct decoding, the frame format conversion is performed. Or, N is the number of child nodes, indicating that all translated pairs can be converted. Or determining whether to perform frame format conversion according to channel quality, routing status, and historical information of feedback data decoding quality between different child nodes.

It should be understood that the foregoing is only an exemplary description, and the embodiment of the present application is not limited thereto. For example, for the primary node, it may also be configured as a receiving state at the beginning, and after a predetermined time, converted to a transmitting state.

Optionally, the configured resource may also include an encoding mode. The configuration of the coding mode includes at least the following cases.

One possible way is to use separate coding methods for the child nodes in the interaction phase.

One possible way is to use joint coding in the cooperation phase, and the joint coding parameters are based on semi-static configuration.

One possible way is to use joint coding in the collaboration phase, as well as the way in which co-existence of independent coding, which is described in the following collaborative behavior.

There are several possible scenarios for the way the encoding of the collaboration phase is converted.

In one possible way, a certain child node can decode the joint encoded data instead of directly.

In a possible way, a certain child node performs joint coding only when all the cooperative feedback data in the joint coding is correctly decoded, and transmits it on the joint coded common resource.

In a possible way, if only a part of the cooperative feedback data is correctly decoded, a certain child node may fill the undecoded correct feedback data with specific bit data (or soft information), perform joint coding, and perform joint coding. Sent on public resources.

In a possible way, for a certain child node, if only part of the cooperative feedback data is correctly decoded, only the correct feedback data can be independently coded and transmitted on the independently coded common resource. At this time, the resources of the independently encoded data and the resources of the jointly encoded data may overlap, and the primary node and the cooperative child node may receive by using an Interference Cancellation (IC) type algorithm.

In a possible manner, when the receiving node is in the receiving state, the child node cooperatively receives the jointly encoded feedback data on the common resource according to the configured common resource parameter, or receives the independently encoded feedback data.

In a possible manner, when the child node is in the transmitting state, according to the configured common resource parameter, the joint encoded feedback data is sent on the common resource, or the feedback data is sent on the own resource, and the other public resources are cooperatively sent to other Independently encoded feedback data for child nodes. Optionally, the power of the non-transmitted resource may be allocated to the sending resource according to a certain rule.

Next, it will be specifically described with reference to the diagram (2) in Fig. 14 .

During the T1 period of the interaction phase, according to the configured frame format pattern, the child nodes S2 and S3 respectively transmit R2 and R3 on the configured common resources F2 and F3; M and S1 receive R2 and R3 on the configured common resources. Suppose S1 correctly decodes R2 and R3.

During the T2 period of the interaction phase, according to the configured frame format pattern, S1 transmits its own R1 on the configured common resource, and cooperatively transmits R2 and R3; M, S2, and S3 receive R1, R2, and R3 on the common resource. Optionally, S2 and S3 determine whether the T3 period is converted to the transmission state according to the decoding condition of the feedback data for cooperative transmission, and determine whether the T3 period is independent coding or joint coding; or forcibly convert to the configured cooperation phase frame format pattern according to Transmit state.

During the T3 period of the collaboration phase, S1, S2, and S3 cooperate to jointly transmit the jointly encoded R1&R2&R3.

During the T4 period of the collaboration phase, S1, S2, and S3 cooperate to jointly transmit the jointly encoded R1&R2&R3.

Optionally, the configured common resource parameters may further include: a rate matching and mapping mode, an RV version, and a modulation mode.

Specifically, the resource mapping manner of the sending data of each child node on the respective time-frequency resources is determined. For example, the rate matching mode is that the data of any transport block size is completely filled in a given time-frequency resource, for example, the mapping mode may be first frequency. The domain re-time domain mapping, or the first-time domain re-frequency domain mapping, etc., for example, the RV version of each transmission may be the same or different, for example, the modulation mode of each transmission may be the same or different.

Optionally, the configured common resource parameters may further include: a HARQ process, an RS sequence, a waveform, a subcarrier width, and the like.

It should be noted that, similar to the embodiments of FIG. 10, FIG. 11, and FIG. 13, the embodiment of FIG. 14 can also introduce an ACK/NACK control channel, thereby avoiding unnecessary transmission and further saving resources. Here, it will not be repeated for brevity.

It should be noted that each of the foregoing configuration information may be included in one information, for example, in a configuration information, indicating a resource, a collaboration resource, a feedback resource, a condition for triggering a frame format conversion, a condition for triggering a transceiver state transition, Time information of the transceiver state, etc. 7 to FIG. 11 are an example in which the master node transmits data to the child node, and FIG. 12 to FIG. 14 are examples in which the child node transmits data to the master node as an example.

It should be understood that the embodiments shown in FIGS. 7 to 14 are merely illustrative, and the present application is not limited thereto. For example, a cycle time can include any number of time units. Alternatively, a cycle time can also be composed of different data transmission directions according to a given or arbitrary pattern. Specifically, in a possible implementation manner, if a cycle time includes at least 8 time units, the data may be sent to the child node in the first 4 time units, and then the next 4 time units are sub- The node sends data to the master node, and so on. Alternatively, the data transmitted by the child node may be received by the master node in the first four time units, and then the next four time units are received by the child node for the data sent by the master node. analogy.

Next, in conjunction with FIG. 15 to FIG. 24, an interaction process in which a master node and a child node receive/transmit a hybrid cooperative transmission is taken as an example for description.

FIG. 15 is a schematic diagram of a method of transmitting data according to another embodiment of the present application.

As shown in Figure 15, there is one Master and three Slaves, which are respectively labeled as Slave1, Slave2, and Slave3. Among them, CMD and RSP respectively represent command data and feedback data. One possible implementation, the Master operates on the entire bandwidth (Whole Bandwith), and the Slave operates on a part of the bandwidth part (BWP). Among them, the introduction of BWP is because the NR band is wider than the LTE band. According to the current spectrum division mode, the NR band is at least 100M, and the radio frequencies of different terminals are different, and the maximum bandwidth that can be supported is different. The concept of BWP. In the embodiment of Fig. 15, Slave1, Slave2, and Slave3 operate on BWP1, BWP2, and BWP3, respectively.

In the embodiment of Fig. 15, one cycle time includes four time units, and the representation of the time unit may be a mini-slot. For example, in the first mini-slot, the Master sends command data CMD1, CMD2, and CMD3 on three frequency resources, and Slave1, Slave2, and Slave3 respectively receive CMD1, CMD2, and CMD3 on the corresponding frequency resources. For some Slaves, some of the other slaves' frequency resources are out-band, so they do not receive the corresponding command data.

Among them, Out-band can be understood as. For a user, because the user's RF capability and other factors may not be able to allocate the full system bandwidth, the unallocated bandwidth is Out-band for the user.

Next, in the embodiment of Fig. 15, how to configure common resource parameters.

Configure common resource parameters and collaborative behavior semi-statically for the Master and a set of Slaves.

Optionally, for each target slave, the common resources include resources of the target slave and resources of some or all of the collaborative slaves. For example, in FIG. 15, for Slave1, the resources of all the cooperative slaves are configured for Slave1, that is, the resources of the cooperative Slave2 and Slave3 are configured. For Slave2, the resources of some collaborative slaves are configured for Slave2, that is, the resources of the collaborative Slave1 are configured, and the resources of the collaborative Slave3 are not configured.

The public resource specifically includes at least one of the following: time-frequency resources, rate matching and mapping mode, RV version, modulation mode, frame format, frequency hopping pattern, HARQ process, RS sequence, OCC sequence, NOMA sequence, waveform, and SCS.

Collaborative behavior can include the behavior of each target slave collaborating with other slaves to receive and transmit signals, as well as the behavior of receiving and transmitting frame format conversions. In the embodiment of the present application, at least one of the following collaborative actions is included.

Within a cycle time, the Master sends and listens in a repeating or periodic configuration of semi-static or dynamic L1 signaling or a time unit of a given pattern. Slaves can be initially configured to listen or transmit status. As shown in Figure 15, in the first mini-slot, Slave1, Slave2, and Slave3 are configured to listen (or receive). In the second mini-slot, Slave2 is converted to the transmit state, and Slave2 and Slave3 are still Listening status.

After the target Slave decoding target command data is correct, the transmission status frame format conversion is performed in the configured time domain (Timing), and optionally, the feedback data of the target slave and/or the collaborative Slaves are repeatedly transmitted on the configured common resources. Command or feedback data. As shown in Figure 15, Slave1 receives the target command data CMD1 in the first mini-slot and decodes it correctly. In the second mini-slot, the third mini-slot, and the fourth mini-slot, The feedback data RSP1, CMD2, and CMD3 are sent on the configured common resources.

After the target Slave fails to decode, it continues to maintain the listening state, and can simultaneously receive command command data and/or cooperative Slaves commands and/or feedback data. As shown in FIG. 15, Slave2 receives the target command data CMD2 in the first mini-slot, and the decoding fails, and continues to receive the command data CMD2 and/or the feedback data RSP1 from the Master and Slave1 in the second mini-slot.

The Master receives the feedback data of the slaves in the configured listening time unit. As shown in Figure 15, the Master receives the feedback data RSP1 of Slave1 in the second mini-slot, the third mini-slot, and the fourth mini-slot; the Master is in the third mini-slot, and the fourth mini-slot The feedback data RSP2 of the Slave 2 is received internally; the Master receives the feedback data RSP3 of the Slave 3 in the fourth mini-slot.

Optionally, the command data and the feedback data of each slave share the same frequency domain resource in a rate matching manner, so the master or the cooperative slave can simultaneously receive the command and feedback data of the slave at a given time-frequency resource. IC class algorithms can be used to improve performance. As shown in FIG. 15, the Master receives the command data CMD2 of the Slave 2 and the feedback data RSP2 of the Slave 2 on the given frequency resource of the third mini-slot.

Optionally, the command data and the feedback data of each slave may be distinguished by using a Cyclic Redundancy Check (CRC) Radio Network Temporary Identity (RNTI) scrambling, for example, RNTI. - CMD and RNTI-RSP.

Optionally, the data of the slave slave can be directly forwarded or coded and forwarded for the data of the coordinated slave, and can be further distinguished for the coded and forwarded. One possible way is that the last time it is intercepted as command data or feedback data, it can be forwarded only for the secondary data, or it can be merged with the same data that was previously heard and then forwarded. Or, another possible way, the last time the interception is a mixture of command data and feedback data, the IC algorithm can be used, the feedback data is extracted, and the feedback data is forwarded, and the command data does not need to be sent.

Alternatively, the effective BWPs of different slaves may be different, and cooperative forwarding is only performed within the respective BWPs.

Optionally, each slave sends data, and can perform reasonable power control on its own feedback data and cooperation data, and prioritize its own reliability.

Optionally, the slaves can be configured to be in a listening state in a certain period, and the masters are configured in the same state as the sending state to exchange and send acknowledgement results to avoid unnecessary cooperative transmission.

It should be noted that, in the embodiment of the present application, an exemplary description is made in the manner that the primary node first sends command data, and then the child node sends feedback data. The embodiment of the present application does not impose restrictions on the order in which command data and feedback data are sent. For example, the child node may first send the feedback data, and then the master node sends the command data; or, the child node and the master node may simultaneously send the feedback data and the command data; or, the different child nodes may be sent in different orders. This embodiment of the present application does not limit this.

Next, the above process will be described in detail with reference to FIG. FIG. 16 takes the process of data transmission in the first four time units by M, S1, and S2 as an example.

The master node sends command data (Command) to the child node, and the child node sends feedback data (Response) to the master node, C1 and R1 are command data and feedback data corresponding to S1, and C2 and R2 are command data and feedback data corresponding to S2. The command data and the feedback data may be carried on the data channel or on the control channel.

The common resource parameter is semi-statically configured for the master node M and the group of child nodes S1 and S2. For S1, the common resource includes the resource of S1 and the resource of S2, and vice versa for S2 and M.

Optionally, configure time-frequency resources. Each time S1 sends and receives its own time-frequency resource size F1 and T, and the time-frequency resource size F2 and T for cooperative transmission and reception; S2 transmits and receives its own time-frequency resource size F2 and T each time, and the time-frequency resource size of cooperative transmission and reception is F1. And T.

Specifically, in FIG. 16, for S1, in the T1 period, S1 receives C1 on F1, and S1 receives C2 on F2. During the T2 period to the T4 period, S1 transmits R1 on F1 and C2 on F2.

Optionally, semi-statically configure collaborative behavior. Collaborative behavior includes changes in frame format, collaborative reception and/or collaborative delivery, and the like. In the embodiment of the present application, at least one of the following collaborative actions is included.

One possible way is to convert the frame format of the master node from the transmit state to the receive state at a given time.

In one possible way, after the child node is decoded correctly, the frame format is switched from the receiving state to the transmitting state at a given time.

In a possible manner, when receiving the state, the child node receives command data sent by the master node and/or other child nodes cooperatively according to the configured common resource parameter, and/or cooperates on other public resources. Receive command data or feedback data sent from the primary node and/or other child nodes.

In a possible manner, when the child node is in the transmitting state, it sends feedback data on its own resources according to the configured common resource parameters, and/or cooperatively transmits command data or feedback data of other child nodes on other common resources.

Next, it will be explained with reference to FIG. During the T1 period, the master node transmits command data C1 and C2 on different frequency domain resources F1 and F2, and the child nodes S1 and S2 receive C1 and C2 on the configured common resources F1 and F2. It is assumed that S1 decodes C1 correctly, and converts from the receiving state to the transmitting state in the T2 period; S2 fails to decode C2, and remains in the receiving state during the T2 period.

During the T2 period, the master node converts from the transmitting state to the receiving state, and receives the feedback data R1 sent by S1. S1 sends R1 on its own resources and cooperates to send C2 on other common resources. S2 receives C2 from S1 on its own resource and R1 from S1 on the cooperative resource. Suppose S2 decodes C2 correctly and transitions from the receive state to the transmit state during the T3 period. Optionally, S1 may directly forward the C2 data that is co-sent, or may decode, re-encode, and forward.

During the T3 period, S1 continues to send R1 and C2. S2 sends R1 and R2. The master node M receives R1 from S1 and S2 on the resources of S1, and receives R2 from S2 and C2 from S1 on the resources of S2. Optionally, the master node M may perform HARQ combining with R1 received by the T2 period for R1 to improve reception performance. Optionally, the master node M can perform the IC and other algorithms to improve the receiving performance according to the known C2 data for the mixed data of C2 and S2 on the S2 resource.

During the T4 period, M continues to receive data from S1 and S2.

Optionally, the configured common resource parameters may further include: a rate matching and mapping mode, an RV version, and a modulation mode.

Specifically, the resource mapping manner of the sending data of each child node on the respective time-frequency resources is determined. For example, the rate matching mode is that the data of any transport block size is completely filled in a given time-frequency resource, for example, the mapping mode may be first frequency. The domain re-time domain mapping, or the first-time domain re-frequency domain mapping, etc., for example, the RV version of each transmission may be the same or different, for example, the modulation mode of each transmission may be the same or different.

Optionally, the configured common resource parameters may further include: a HARQ process, an RS sequence, a waveform, a subcarrier width, and the like.

In the embodiment of the present application, the master node may also continuously send. Fig. 17 is a diagram showing the continuous transmission of the master node. 17 is mostly similar to FIG. 16, and is not described in detail herein for the sake of brevity. Next, the difference between the embodiment of Fig. 17 and the embodiment of Fig. 16 will be mainly described.

When the cooperative behavior is semi-statically configured, the frame format of the master node is switched from the transmit state to the receive state at a given time, wherein the given time is after the K8th T time, where K8>1, so that the master node M can continuously send K8 command data, which can improve the reliability of command data.

During the T2 period, S2 simultaneously receives C1 from the autonomous node and R1 from S1 on the cooperative resource.

Specifically, in one possible manner, C1 and R1 may be distinguished by RNTI-CMD and RNTI-RSP scrambling of CRC. Alternatively, in a possible manner, S2 can directly forward C1 and R1; it can also be decoded and coded and forwarded, and the IC algorithm can be used to extract and feed back the feedback data R1. The command data C1 is not sent because R1 occurs after C1, so if R1 occurs, R1 is data that needs to be transmitted cooperatively.

In this embodiment of the present application, the child node may also be configured to periodically be in the receiving state. Figure 18 shows a schematic diagram of a child node periodically in a receiving state. 18 is mostly similar to FIG. 16, and is not described in detail herein for the sake of brevity. Next, the difference between the embodiment of Fig. 18 and the embodiment of Fig. 16 will be mainly described.

When the cooperative behavior is semi-statically configured, the frame format of the master node is switched from the transmit state to the receive state at a given time, where the given time is after the K9th T time, where K9 ≥ 1 (including the case of Figures 16 and 17) ), so that the master node M can continuously transmit K9 command data.

When the cooperative behavior is semi-statically configured, after the child node is decoded correctly, the frame format is switched from the receiving state to the transmitting state at a given time, wherein the given time is after the Lth T time, where L≥0 (including the Case), L=0 means the next time is converted.

In a possible manner, the pattern of the reception and transmission frame format of the S1 after the Lth T time can be configured, and the pattern is a pattern of the relative time, which can be numbered starting from the L time, as shown in FIG.

In a possible manner, the pattern of the S1 reception and transmission frame format after the Lth T time can be configured, and the pattern is an absolute time pattern, which can be numbered starting from the start of the cycle time, as shown in FIG.

In a possible manner, when multiple sub-nodes simultaneously convert frame formats, different patterns can be defined for different sub-nodes, thereby ensuring that different sub-nodes can fully exchange feedback data and improve resource utilization, as shown in FIG. 21.

In the embodiment of Fig. 18, during the T1 period, M transmits C1 on F1 and M transmits C2 on F2. S1 and S2 receive C1 and C2 on F1 and F2.

During the T2 period, S2 simultaneously receives C1 from the autonomous node and R1 from S1 on the cooperative resource.

Specifically, in one possible manner, C1 and R1 may be distinguished by RNTI-CMD and RNTI-RSP scrambling of CRC. Alternatively, in a possible manner, S2 can directly forward C1 and R1; it can also be decoded and coded and forwarded, and the IC algorithm can be used to extract and feed back the feedback data R1. The command data C1 is not sent because R1 occurs after C1, so if R1 occurs, R1 is data that needs to be transmitted cooperatively.

In the T3 period, S1 converts the pattern according to the configured frame format, switches to the receiving state, and receives the feedback data R2 from S2.

In the T4 period, S1 sends R1 and R2, and S2 also sends R1 and R2. The master node M does not receive the mixed data of R2 and C2 for S2 at the same time, but only receives R2, so the receiving performance is improved.

Different child nodes may concurrently transmit multiple services, so some child nodes cannot be allocated for some resources in the common resource. In addition, the concept of BWP is introduced in the 5G standard, that is, the activation bands of different sub-nodes do not necessarily occupy the entire system spectrum resources, but only a part of the spectrum resources, and different sub-nodes may allocate different spectrum resources. These resources may not overlap, or partially overlap, or completely overlap. Figure 22 shows a schematic diagram of the cooperative bandwidth of different child nodes.

On the basis of the embodiment of Fig. 16, the embodiment of Fig. 22 has the following differences.

The common resource parameter is semi-statically configured for the master node M and the group of child nodes S1 and S2, wherein the resource specifically includes at least one of the following:

Time-frequency resource: The time-frequency resource size F1 and T of S1 each time transmitting its own data, and the cooperative transmission time-frequency resource size is F2 and T. Each time S2 transmits the time-frequency resource sizes F2 and T of its own data, there is no time-frequency resource for cooperative transmission.

For the case where multiple child nodes cooperate, different child nodes can perform cooperative reception/send on overlapping common resources.

Due to the short cycle time in industrial applications, the fading variation of the wireless channel is small in such a short period of time, so the time diversity gain of multiple transmissions in the time domain is small, and in order to improve the reliability of transmission, frequency hopping can be adopted. The mode obtains the frequency domain fading diversity of the channel. Figure 23 shows a schematic diagram of frequency hopping.

On the basis of the embodiment of Fig. 16, the embodiment of Fig. 23 has the following differences.

Configure the hopping pattern of different sub-nodes. As shown in Figure 23, the frequency domain resources of S1 in the period from T1 to T4 are respectively configured as F1/F2/F1/F2, and the frequency domain resource configuration of S2 is reversed. Like other common resource parameters, each child node needs to know the hopping pattern of other child nodes in addition to its own hopping pattern, thereby performing cooperative reception/transmission.

Due to the band limitation of common resources, in order to access more sub-nodes at the same time, a multiplexing method needs to be considered, and multiplexing may be time-division multiplexing, frequency division multiplexing, space division multiplexing, and the like. Fig. 24 shows a schematic diagram of multiplexing.

On the basis of the embodiment of Fig. 16, the embodiment of Fig. 24 has the following differences.

Configure multiplexing patterns for different child nodes. In a possible way, the multiplexing pattern may be a time division multiplexing pattern, which is grouped for different child nodes, and different groups occupy different or partially overlapping time units. Alternatively, in a possible manner, the multiplexing pattern may be a frequency division multiplexing pattern, which is grouped for different child nodes, and different groups occupy different or partially overlapping frequency domain units. Alternatively, in a possible manner, the multiplexing pattern may be a space division multiplexing pattern, and may further correspond to different OCC orthogonal sequences, or different NOMA non-orthogonal sequences, or different Precoding matrices (corresponding to multi-user multi-entry) Multiple layers of Multi-User Multiple-Input Multiple-Output (MU-MIMO) transmission, etc.

Figure 24 shows the code division multiplexing mode of OCC or NOMA in space division multiplexing. S1 and S3 use different Code1 and Code3 for code division multiplexing, and S2 and S4 use different Code2 and Code4 for code division multiplexing. Like other common resource parameters, each child node needs to know the multiplexing pattern of other child nodes in addition to its own multiplexing pattern, thereby performing cooperative reception/transmission.

In the above, FIG. 15 to FIG. 24 illustrate an interaction process of receiving/transmitting a hybrid cooperative transmission by a master node and a child node. Referring to FIG. 25 to FIG. 34, the master node and the child node receive/transmit mixed cooperation. An interactive process with ACK/NACK feedback is described as an example.

FIG. 25 is a schematic diagram of a method of transmitting data according to another embodiment of the present application.

As shown in Figure 25, there is one Master and three Slaves, which are respectively labeled as Slave1, Slave2, and Slave3. Among them, CMD and RSP respectively represent command data and feedback data. One possible implementation, the Master operates on the entire bandwidth, and the Slave operates on a part of the bandwidth part (BWP).

In the embodiment of FIG. 25, one cycle time includes four time units, and the representation of the time unit may be a mini-slot. In each mini-slot, there are command data or feedback data, as well as ACK/NACK information.

Configure common resource parameters and collaborative behavior semi-statically for the Master and a set of Slaves.

Optionally, in a cycle time, each time unit is configured as a self-contained frame format, such as sending a dominant frame, indicating that the first frame is received first, or the first time is received, and the number of transmitted symbols is greater than Or equal to the number of received symbols; if the interception is dominant, it means that it is received first or later, or it means that it is received first, and the number of received symbols is greater than or equal to the number of transmitted symbols. The Master is initially configured to send a dominant frame, and the Slaves initially configures to listen to the dominant frame.

In the embodiment of the present application, the cooperative behavior of the semi-static configuration of the master and the set of slaves includes at least one of the following.

After the target Slave decoding target command data is correct, the transmission state at the rear of the time unit is converted into a listening state, and the NACK of other slaves is intercepted; and the next time unit frame format is converted into a transmission dominant frame, in the configuration. The feedback data of the target slave is sent on the common resource and the command or feedback data of the collaborative Slaves that feeds back the NACK.

After the target slave fails to decode the target command data, it feeds back NACK and continues to maintain the interception dominant, while receiving the target command data and the command or feedback data of the cooperative Slaves.

The Master receives the feedback data of the slaves in the configured listening time unit, and feeds back the ACK/NACK information.

Optionally, after receiving the ACK of the feedback data, if the target slave receives the NACK of the other slave, the time unit frame format of the subsequent timing domain (Timing) is converted into the interception dominant detection to listen to the cooperative slave. The data.

Optionally, the Master and all the Slaves need to receive the ACK of all the Slaves before performing the frame format switching, and then enter the cooperative feedback phase of the RSP, and the control data transmission and the feedback data transmission are separated in time as a whole.

Optionally, the command data and the feedback data for each slave may be distinguished by using RNTI-CMD and RNTI-RSP scrambling of the CRC.

Optionally, the data of the slave slave can be forwarded or decoded and forwarded for the data of the cooperative slave.

Alternatively, the effective BWPs of different slaves may be different, and each slave performs cooperative forwarding only within the respective BWP.

Optionally, each slave sends data, and can perform reasonable power control on its own feedback data and cooperation data, and prioritize its own reliability.

Optionally, each slave only feeds back NACK.

Optionally, the ACK/NACK of the slave part or all of the slaves may be jointly coded by the ACK/NACK, and may be sent in the form of a data packet, which may be distinguished from the command data by using RNTI, and may be configured to send the joint coded ACK. /NACK parameters such as Timing and period.

It should be noted that, in the embodiment of the present application, an exemplary description is made in the manner that the primary node first sends command data, and then the child node sends feedback data. The embodiment of the present application does not impose restrictions on the order in which command data and feedback data are sent. For example, the child node may first send the feedback data, and then the master node sends the command data; or, the child node and the master node may simultaneously send the feedback data and the command data; or, the different child nodes may be sent in different orders. This embodiment of the present application does not limit this.

The embodiment of FIG. 25 considers ACK/NACK feedback, and therefore needs to configure a time unit for transmitting and receiving a control channel, mainly considering two feasible frame structures, a conventional frame structure based on LTE and 5G systems, as shown in FIG. Show.

In the traditional frame structure, two or more standard time units (Duration) constitute a complete transmission time unit, where the standard time unit refers to the time unit defined in the standard, which may be Short-TTI, slot, Sub-Frame, Frame. , mini-slot, symbol, etc. The transmission time unit includes reception/transmission of command or feedback data, and transmission/reception of a corresponding ACK/NACK. For example, in the case of a child node, in the diagram (1) in FIG. 26, T1 transmits feedback data, and T2 receives an ACK/NACK control message fed back by the master node; in FIG. 26 (2), T1 receives the master. The command data sent by the node, and T2 feeds back the ACK/NACK control message of the command data.

It should be noted that the lengths of time T1 and T2 may be equal or not equal. T1 and T2 may be adjacent to each other, or may be non-adjacent times, which is not limited by the embodiment of the present application. In addition, the embodiment of the present application does not limit how to configure T1 and T2. For example, the time of T1 and T2 may be semi-static RRC configuration, or may be configured by the Group Common L1 control message, or configured by user-level L1 control message. . It should be understood that T1 and T2 are equally applicable to the flexible frame structure of a 5G system.

Another frame structure is based on a Self-Contain frame structure in a 5G system, as shown in FIG.

The Self-Contain frame structure includes the following three features: DL symbols, UL symbols in the same subframe, or GP symbols and/or Flexible Symbols; the same subframe contains DL data and corresponding HARQ feedback; UL scheduling information and corresponding data information are transmitted in the same subframe. In the Self-Contain frame structure, the transmission time unit and the reception time unit are further divided in a standard time unit (Duration), so a standard time unit can constitute a completed transmission time unit. Where GP means no power is transmitted. The graph (1) in Fig. 27 corresponds to the transmission dominant frame, and the graph (2) in Fig. 27 corresponds to the reception dominant frame.

The embodiments of the present application are applicable to both frame structures. For illustrative purposes, they are all represented by a Self-Contain frame structure (the GP is not shown by default), and different time stamps (such as T1 and T2) are used to distinguish the data transmission and reception time and the ACK/NACK control message transmission and reception time, and set the T2 time. Less than T1 time (because the ACK/NACK control message has a lower resource occupancy rate than the data).

It should be noted that the foregoing two frame structures are only exemplary, and the embodiments of the present application may be applicable to other possible frame structures or frame structures of other systems, and the embodiments of the present application are not limited thereto.

Next, the above process will be described in detail with reference to FIG.

The master node sends command data (Command) to the child node, and the child node sends feedback data (Response) to the master node, C1 and R1 are command data and feedback data corresponding to S1, and C2 and R2 are command data and feedback data corresponding to S2. The child node may only feed back NACK information, and C2N indicates NACK information of the decoded C2 fed back by S2. The master node may feed back NACK and ACK information, R1N/R2N is the NACK information of the decoded R1/R2 fed back by M, and R1A/R2A is the ACK information of the decoded R1/R2 fed back by M. The command data and the feedback data are carried on the data channel, and the data channel corresponds to T1/T3/T5/T7 in FIG. 28, and the A/N is carried on the control channel, and the control channel corresponds to T2/T4/T6/T8 in FIG. 28.

The common resource parameter is semi-statically configured for the master node M and the group of child nodes S1 and S2. For S1, the common resource includes the resource of S1 and the resource of S2, and vice versa for S2 and M.

Optionally, configure data time-frequency resources. Each time S1 sends and receives its own time-frequency resource size F1 and T, the time-frequency resource size of cooperative transmission and reception is F2 and T. Each time S2 sends and receives its own time-frequency resource size F2 and T, the time-frequency resource size of cooperative transmission and reception is F1 and T. Where T corresponds to T1/T3/T5/T7.

Optionally, the time-frequency resource of the ACK/NACK control message is configured. Each time S1 sends and receives the time-frequency resource sizes F1 and T of its own control message, the time-frequency resource size of the cooperative transmission and reception control message is F2 and T. Each time S2 sends and receives the time-frequency resource size F2 and T of the control message, the time-frequency resource size of the cooperative transmission and reception control message is F1 and T. Among them, T corresponds to T2/T4/T6/T8.

Optionally, semi-statically configure collaborative behavior. Collaborative behavior includes changes in frame format, collaborative reception and/or collaborative delivery, and the like. For example, the initial master node is configured to be in a transmit state, corresponding to a self-contained transmit dominant frame; the child node is configured as a receive state, corresponding to a receive-dominant frame of the Self-Contain.

One possible way is to convert the frame format of the master node from a transmit frame to a receive frame at a given time, or from a transmit dominant frame to a receive dominant frame.

In one possible way, after the child node is decoded correctly, the frame format is switched from the receiving state to the transmitting state at a given time. This state change can occur within a transmission frame, such as a transmitted symbol that receives a dominant frame is converted to a received symbol.

In a possible manner, when the data channel receives the state, the child node receives the command data sent by the master node and/or other child nodes cooperatively on the own resource according to the configured common resource parameter. Or, according to the ACK information, no longer receives its own command data, and cooperatively receives command data or feedback data sent from the master node and/or other child nodes on other common resources. Or the command data or the feedback data is no longer received according to the ACK corresponding to the other child nodes.

In a possible manner, when the data node is in the data channel transmission state, the child node sends the feedback data according to the configured common resource parameter on the self resource, or retransmits the feedback data according to the NACK fed back by the master node, or according to the ACK fed back by the master node. The transmission of the feedback data is terminated, or the feedback data is terminated according to the NACK that is not received by the primary node. On other common resources: cooperatively transmit command data or feedback data of other child nodes, or retransmit the command data according to NACK cooperation of other child nodes or retransmit the feedback data according to the NACK of the master node, or terminate according to ACK of other child nodes. The cooperative retransmission command data terminates the cooperative retransmission feedback data according to the ACK of the master node, or terminates the cooperative retransmission command data according to the NACK that does not receive the other child nodes or terminates the cooperative retransmission feedback data according to the NACK that does not receive the master node.

In a possible manner, when the control node receives the control channel, the child node receives, on its own resource, a control message such as an ACK/NACK corresponding to the feedback data jointly sent by the master node and/or other child nodes according to the configured common resource parameter. And cooperatively receiving control messages such as ACK/NACK corresponding to command data or feedback data sent by the master node and/or other child nodes on other common resources.

In a possible manner, when the control node transmits the control channel, the child node sends a control message such as ACK/NACK corresponding to the command data on its own resource according to the configured common resource parameter, and cooperatively transmits the other child nodes on other common resources. A control message such as ACK/NACK corresponding to the command data or the feedback data.

Specifically, in FIG. 28, during the data channel T1 period, the master node transmits command data C1 and C2 on different frequency domain resources F1 and F2, and the child nodes S1 and S2 receive C1 and on the configured common resources F1 and F2. C2. It is assumed that S1 decodes C1 correctly, the control channel is converted from the transmit state to the receive state during the T2 period, and the subsequent frame format is converted from the receive dominant frame to the transmit dominant frame. Suppose S2 decodes the C2 error and still maintains the transmit state of the control channel during the T2 period.

During the control channel T2 period, S2 feeds back the decoding error information C2N of C2 and is received by the master node and the child node S1.

During the data channel T3 period, the master node converts from the transmitting state to the receiving state, and receives the feedback data R1 of the child node S1. S1 sends R1 on its own resource and cooperatively sends C2 on other common resources according to C2N. S2 receives C2 from S1 on its own resource and R1 from S1 on the cooperative resource. Assuming that S2 decodes C2 correctly, the control channel is converted from the transmit state to the receive state during the T4 period, and the subsequent frame format is converted from the receive dominant frame to the transmit dominant frame. Optionally, S1 may directly forward the C2 data that is co-sent, or may decode, re-encode, and forward.

During the control channel T4 period, the master node feeds back the decoding error message R1N of R1 and is simultaneously received by S1 and S2.

During the data channel T5 period, S1 continues to transmit R1 according to R1N, and since C2N is not received, the cooperative transmission C2 is stopped. S2 sends R2 and sends R1 cooperatively according to R1N. The master node M receives R1 from S1 and S2 on the resources of S1, and receives R2 from S2 on the resources of S2. Optionally, the master node M may perform HARQ combining with R1 received in the T3 period for R1 to improve the receiving performance.

During the control channel T6 period, the master node feeds back R1A and R2N and is simultaneously received by S1 and S2.

During the data channel T7 period, S2 retransmits R2 according to R2N. S1 terminates the transmission of R1 according to R1A, and since R2 feedback data is not received, R2 cannot be cooperatively transmitted.

During the control channel T8 period, the master node feeds back R2A and is received by S2.

Optionally, the configured common resource parameter may further include: a rate matching and mapping mode of the data, an RV version, and a modulation mode.

Specifically, the resource mapping manner of the sending data of each child node on the respective time-frequency resources is determined. For example, the rate matching mode is that the data of any transport block size is completely filled in a given time-frequency resource, for example, the mapping mode may be first frequency. The domain re-time domain mapping, or the first-time domain re-frequency domain mapping, etc., for example, the RV version of each transmission may be the same or different, for example, the modulation mode of each transmission may be the same or different.

Optionally, the configured common resource parameter may further include: a sequence resource of the ACK/NACK control message, or a rate matching and mapping manner. Specifically, when only ACK/NACK is carried, the bearer may be carried in a sequence manner; for carrying more control messages, such as CSI measurement information, etc., it may be carried in a manner similar to data encoding and rate matching.

Optionally, the configured common resource parameters may further include: a HARQ process, an RS sequence, a waveform, a subcarrier width, and the like.

In the embodiment of the present application, the master node may also continuously send. Fig. 29 is a diagram showing the continuous transmission of the master node. 29 is mostly similar to FIG. 28 and will not be described in detail herein for the sake of brevity. Next, the difference between the embodiment of Fig. 29 and the embodiment of Fig. 28 will be mainly described.

On the basis of the scheme in Fig. 28, there are the following differences.

When the cooperative behavior is semi-statically configured, the frame format of the master node is switched from the transmission frame to the reception frame at a given time, or from the transmission dominant frame to the reception dominant frame, wherein the given time is after the K10th T time. Where K10>1, the master node M can continuously send K10 command data continuously, thereby improving the reliability of the command data.

When semi-statically configuring cooperative behavior, one possible way: the frame format of the primary node is converted from the transmitted frame to the received frame according to a certain criterion according to the received ACK/NACK fed by the child node, or converted from the transmitted dominant frame to the received Dominant frame. Wherein, the criterion includes at least one of the following cases.

1. Receive ACK information fed back by all child nodes, and then perform frame format conversion.

2. Receive the ACK information fed back by a given set of sub-nodes, and then perform frame format conversion. The given set of sub-nodes may be determined according to channel quality, routing status, number of transmissions, ACK/NACK information ratio, and the like. The ratio of the ACK/NACK information may be: after receiving the N ACK information, performing frame format conversion, N≥1; or the ACK/NACK information ratio may also be a preset value, and performing frame format conversion. The preset value may be determined according to the user himself.

3. The NACK information fed back by all the sub-nodes is not received, and then the frame format conversion is performed.

4. The NACK information fed back by a certain sub-node is not received, and then the frame format conversion is performed. Among them, a given set of child nodes is similar to 2.

In the embodiment of FIG. 29, during the data channel T3 period, S2 simultaneously receives C1 from the autonomous node and R1 from S1 on the cooperative resource.

Specifically, in a possible manner, the C1 and R1 data can be distinguished by using CRC RNTI-CMD and RNTI-RSP scrambling. Alternatively, in a possible manner, S2 can directly forward C1 and R1; it can also be decoded and coded and forwarded, and the IC algorithm can be used to extract and feed back the feedback data R1. The command data C1 is not sent because R1 occurs after C1, so if R1 occurs, R1 is data that needs to be transmitted cooperatively.

In this embodiment of the present application, the child node may also be configured to periodically be in the receiving state. Figure 30 shows a schematic diagram of a child node periodically in a receiving state. Figure 30 is mostly similar to Figure 28 and will not be described in detail herein for the sake of brevity. Next, the difference between the embodiment of Fig. 30 and the embodiment of Fig. 28 will be mainly described.

On the basis of the scheme in Fig. 28, there are the following differences.

When the cooperative behavior is semi-statically configured, the frame format of the master node is switched from the transmission frame to the reception frame at a given time, or from the transmission dominant frame to the reception dominant frame, wherein the given time is after the K11th T time. Where K11 ≥ 1 (including the case of Figs. 28 and 29), so that the master node M can continuously transmit K11 command data.

When the cooperative behavior is semi-statically configured, after the child node is decoded correctly, the frame format is switched from the receiving state to the transmitting state at a given time. This state change can occur within a transmission frame, such as a transmitted symbol that receives a dominant frame is converted to a received symbol. Wherein, the given time is after the Lth T time, where L ≥ 0 (including the case of Fig. 28), and L = 0 means the next time is converted.

The following three pattern configurations are similar to the embodiment in FIG. 18. The pattern can be configured separately for the data channel and the control channel, or can be configured jointly. For the Self-Contain frame format, each frame in the pattern may be any one of a transmit dominant frame, a received dominant frame, a full transmit frame, and a full received frame.

In a possible manner, the pattern of the reception and transmission frame format of S1 after the Lth T time can be configured, and the pattern is a pattern of relative time, which can be numbered starting from the L time, as shown in FIG.

In a possible manner, the pattern of the S1 reception and transmission frame format after the Lth T time can be configured, and the pattern is an absolute time pattern, which can be numbered starting from the beginning of the cycle time, as shown in FIG.

In a possible manner, for multiple sub-nodes to simultaneously convert frame formats, different patterns can be defined for different sub-nodes, thereby ensuring that different sub-nodes can fully exchange feedback data and improve resource utilization, as shown in FIG.

In the embodiment of FIG. 30, during the data channel T5 period, S1 is configured as a receiving state according to the pattern, thereby receiving the feedback data R2 of S2 to perform cooperative transmission of R2 according to the decoding error message R2N in the T7 period.

It should be noted that, in the embodiment in which the primary node master and the child node Slave receive/transmit mixed cooperative transmission and have ACK/NACK feedback, the embodiment also includes the following in FIG. 22, FIG. 23, FIG. Example. The ACK/NACK part can be added on the basis of FIG. 22 to FIG. 24, which is succinct and will not be described again.

In the embodiment of the present application, the ACK/NACK conversion frame format of the child node or the cooperative child node may be specifically described below.

FIG. 34 shows a schematic diagram of converting a frame format according to a cooperative child node NACK. On the basis of the scheme in Fig. 28, there are the following differences.

The cooperative behavior of the primary node M and the set of child nodes S1 and S2 is semi-statically configured. The case of frame format conversion may also include the following two cases.

In a possible manner, if the NACK information sent by other sub-nodes is received on the control channel, optionally, when the sub-node receives the ACK information of the self-feedback data or decodes the self-data correctly, the frame format is at a given time. Switch from the transmit state to the receive state. This state change can occur within a transmission frame, such as a transmitted symbol that transmits a dominant frame is converted to a received symbol.

In a possible manner, if the NACK and ACK information sent by the other multiple sub-nodes are received on the control channel, optionally, when the sub-node receives the ACK information of the self-feedback data or decodes the self-data correctly, according to certain criteria Determines whether the frame format is converted from the transmit state to the receive state at a given time. This state change can occur within a transmission frame, such as a transmitted symbol that transmits a dominant frame is converted to a received symbol. The certain criterion may be determined according to the number of transmissions of multiple child nodes, the channel quality, the ratio of NACK and ACK, and the like.

With the embodiment of the present application, the feedback data of the child nodes that need to be cooperatively transmitted can be received as early as possible, and the data is cooperatively transmitted at the next moment to improve the receiving performance of the feedback data.

In the embodiment of FIG. 34, during the control channel T6 period, the master node feeds back R1A and R2N and is simultaneously received by S1 and S2, and S1 sets the T7 period data channel from the ACK of the feedback data of the self and the NACK of the feedback data of S2. The transmit state is converted to the receive state (the corresponding transmit dominant frame is converted to a full receive frame).

During the data channel T7 period, S2 retransmits R2 according to R2N, and S1 receives R2.

During the control channel T8 period, S1 receives the A/N message of R2 fed back by the master node to determine whether to jointly transmit R2 at the subsequent T9 time.

In this embodiment of the present application, the frame format may also be converted according to the ACK according to the child node itself.

On the basis of the scheme in Fig. 28, there are the following differences.

The cooperative behavior of the primary node M and the set of child nodes S1 and S2 is semi-statically configured. The case of frame format conversion may also include the following two cases.

In a possible manner, after the sub-node receives the ACK information of the self-feedback data or decodes the self-data correctly, optionally, if the NACK information sent by other sub-nodes is received on the control channel, the frame format is at a given time. Switch from the transmit state to the receive state. This state change can occur within a transmission frame, such as a transmitted symbol that transmits a dominant frame is converted to a received symbol.

In a possible manner, after the sub-node receives the ACK information of the self-feedback data or decodes the self-data correctly, optionally, if the NACK and ACK information sent by the other multiple sub-nodes are received on the control channel, according to certain criteria Determines whether the frame format is converted from the transmit state to the receive state at a given time. This state change can occur within a transmission frame, such as a transmitted symbol that transmits a dominant frame is converted to a received symbol. The certain criterion may be determined according to the number of transmissions of multiple child nodes, the channel quality, the ratio of NACK and ACK, and the like.

With the embodiment of the present application, the feedback data of the child nodes that need to be cooperatively transmitted can be received as early as possible, and the data is cooperatively transmitted at the next moment to improve the receiving performance of the feedback data.

Taking FIG. 34 as an example, during the control channel T6 period, the master node feeds back R1A and R2N, and is simultaneously received by S1 and S2, and S1 transmits the T7 period data channel from the transmitting state according to the ACK of the self-feedback data and the NACK of the feedback data of S2. Converted to receive state (the corresponding transmit dominant frame is converted to full receive frame).

Taking FIG. 34 as an example, in the data channel T7 period, S2 retransmits R2 according to R2N, and S1 receives R2.

The master node M and a group of child nodes S1, S2 are semi-statically configured with cooperative behavior, and the pattern configuration of power allocation is increased.

One possible way is to distribute the unsent power evenly to other resources that need to be sent for user resources that do not need to be co-transmitted (such as ACK has been received, or no NACK is received).

One possible way is to allocate unsent power to other resources that need to be sent according to certain criteria for user resources that do not need to be transmitted cooperatively (such as ACK has been received, or no NACK is received). The criterion can perform power allocation according to channel quality, routing state, number of transmissions, user number, and the like of different users.

In addition, optionally, in the embodiment of the present application, the master node may jointly feed back ACK/NACK. On the basis of the scheme in Fig. 28, there are the following differences.

The primary node feeds back some or all of the ACK/NACKs of the child nodes, and these ACK/NACKs can be jointly encoded and sent to the child nodes in the form of a data packet.

One possible way to occupy a proprietary control channel;

One possible way is to occupy the data channel and distinguish it from the normal command data in at least one of the following: a specific time-frequency resource, a specific RS sequence, a specific CRC-RNTI, and the like.

In a possible manner, the jointly encoded ACK/NACK may adopt a multiple transmission manner, and configure a Timing time, a period, a frame format and the like for transmitting a joint coded ACK/NACK.

Based on the foregoing technical solution, on the one hand, for the target child node, the first data may be simultaneously transmitted with the primary node and the coordinated child node on the first time-frequency resource; and the primary node may be simultaneously connected to the primary time-frequency resource. The cooperative child node transmits the second data. Therefore, the time delay of the task time can be saved, and the efficiency can be further improved. On the other hand, on the first time-frequency resource, the target child node can transmit data with the master node or transmit data with the cooperative child node, which can further save resources. In addition, the target child node can receive data from the master node and the cooperative child node at the same time, which can improve the probability that the target child node receives the data. In addition, in the embodiment of the present application, no additional scheduling and BWP switching are required, and the delay is reduced.

In addition, through the embodiments of the present application, the frequency domain channel diversity gain of multiple users can also be obtained.

It should be understood that the foregoing embodiment uses the master node Master and the child node Slave as an example to describe the relationship between the configuration parameters and the frame format and the cooperative behavior, but this should not be construed as limiting the application.

The above lists the different configuration parameters, the frame format, the relationship of the cooperative behavior in different interaction modes, and the transition of the state of the frame format of the child node/master node in different interaction modes, cooperative behavior, and the like. However, it should be understood that this is merely an example given for ease of understanding and should not be construed as limiting the application. The configuration parameters and frame formats enumerated above are also determined based on the existing schemes, and the present application does not exclude the possibility of giving new definitions in future protocols.
