DETAILED DESCRIPTION OF THE INVENTION

Here will be described in detail the embodiments of the invention, which are shown in the accompanying drawings. When in the following description reference is made to the accompanying drawings, the same numbers in different drawings represent the same or similar elements, unless otherwise indicated. The embodiments of the invention described in the following examples do not represent all the embodiments of the present invention. Rather, they are merely examples of apparatus and method in accordance with certain aspects of the present invention, which are described in detail in the appended claims.

In V2X New Radio (NR) technology, unicast and multicast services support direct communication using a back-to-back and retransmission mechanism based on hybrid automatic repeat request (HARQ) in the physical layer. For unicast services, the side receiving the data returns an acknowledgment (ACK) when the data is successfully received (data is successfully decoded), and returns a negative acknowledgment (NACK) when the data is not successfully received (an error occurs while decoding the data). For multicast services, two methods for implementing HARQ feedback are supported. In one method, the side receiving the data returns NACK only when the data was not successfully received, and otherwise does not return any signal. In another method, each side receiving the data returns an ACK when the data was successfully received and returns a NACK when the data was not successfully received.

The network device allocates a physical uplink control channel (PUCCH) time-frequency resource for transmitting HARQ feedback for forward link data to the data transmitting side through downlink signaling. The network device may also allocate a PUCCH time-frequency resource for transmitting uplink information such as HARQ feedback for downlink data, scheduling request (SR) and channel state information (CSI) to the side transmitting data through downlink signaling. The data transmitting side selects PUCCH time-frequency resources to transmit other uplink information other than HARQ feedback for forward link data and HARQ feedback for forward link data based on the PUCCH time-frequency resources assigned by the network device.

However, a PUCCH time-frequency resource for transmitting said other uplink information and a PUCCH time-frequency resource for transmitting HARQ feedback for forward link data selected by the data transmitting side may overlap with each other. When the PUCCH time-frequency resource for transmitting said other uplink information overlaps with the PUCCH time-frequency resource for transmitting HARQ feedback for the forward link data, it is currently unclear how to transmit the HARQ feedback information for the forward link data.

To solve the problems of the prior art, the invention provides a feedback method, a feedback device, and a storage medium.

The feedback method provided in any embodiment of the invention can be applied in a communication scenario in which two devices communicate directly, such as in a V2X scenario involving a vehicle and another node. V represents a device installed on a vehicle, and X represents any object that interacts with a device installed on a vehicle. At present, X mainly includes a vehicle-mounted device, a portable device, a roadside infrastructure, and a network. The V2X communication mode includes interaction between vehicle and vehicle (V2V, vehicle to vehicle), vehicle and infrastructure (V2I, vehicle to infrastructure), vehicle and pedestrian (V2P, vehicle to pedestrian), and vehicle and network (V2N). , vehicle to network). In the invention, a communication scenario in which two devices communicate directly may be a communication scenario involving device-to-device (D2D) communication. The direct communication device in embodiments of the invention may include a portable device, a vehicle-mounted device, a wearable device, a wireless computing device, or other data processing device connected to a wireless modem, and various forms of user equipment (UE, user equipment), mobile station (MS, mobile station), terminal, terminal equipment, etc. For ease of description, the embodiments of the invention will be described in terms of a scenario in which vehicle-mounted devices communicate directly. The vehicle-mounted direct communication device includes a vehicle-mounted device configured as a data-transmitting side and a vehicle-mounted device configured as a data-receiving side.

Fig. 1 is a schematic diagram illustrating a scenario in which vehicle-mounted devices communicate. The network device configures various transmission parameters for data transmission for the device 1 installed on the vehicle. The vehicle-mounted device 1 is configured as the data transmitting side. The vehicle-mounted device 2 is configured as the data receiving side. The two devices installed on the vehicle communicate directly. The communication link for communication between the network device and the device installed on the vehicle includes an uplink and a downlink. Communication between the devices installed on the vehicle is a direct connection. In the cellular-vehicle-to-everything (C-V2X, cellular-vehicle to everything) scenario, communication between a vehicle-mounted device and another device may include transmission through a base station and a core network. In other words, the downlink and uplink between a terminal device and a base station in an existing cellular network are used for communication, and a forward link between devices can be directly used for communication. Compared with Uu interface communication, forward link communication has characteristics such as small time delay, small overhead, etc., so that direct link communication is suitable for direct communication between a device installed on a vehicle. vehicle, and another neighboring device geographically located next to the device installed on the vehicle.

V2X Direct Communication in a Long Term Evolution (LTE) system can only support V2X applications in some basic safety aspects, for example, performing voice broadcasting based on basic safety messages (BSM), such as mass alert messages (CAM, cooperative awareness message) or a decentralized environmental notification message (DENM). Recently, with the development of technologies such as autonomous driving, new V2X technology performance requirements are being proposed to support new vehicle-to-all-site (V2X) communication services. The 3rd generation partnership project (3GPP) has planned the use of 5G technologies to support new services and V2X communication scenarios as an important Rel 16 content. meet the new V2X communication, including vehicle grouping, advanced sensors, advanced driving, remote driving. As a general rule, NR V2S direct link should provide faster link speed, lower link delay, and more reliable link quality.

Direct link unicast and multicast services support the use of a hybrid automatic repeat request (HARQ) feedback and retransmission mechanism in the physical layer. For unicast services, the receiving end of the data returns an acknowledgment (ACK) when the data was successfully received (data successfully decoded) and returns a negative acknowledgment (NACK) when the data was not successfully received (data decoding error occurs). For multicast services, two methods for implementing HARQ feedback are supported. In one method, the side receiving the data returns NACK only when the data was not successfully received, and otherwise does not return any signal. In another method, each side receiving the data returns an ACK when the data was successfully received and returns a NACK when the data was not successfully received.

In the prior art, NR V2X supports the Mode 1 resource allocation method. The network device allocates a time-frequency resource to a terminal configured as a data transmitting side through downlink signaling. The terminal configured as the data transmitting side uses the dedicated time-frequency resource to transmit forward link control information and forward link data. There may be three cases based on different ways of allocating time-frequency resources by downlink signaling.

A, Type 1 Grant configured: The network device transmits time-frequency resource information to the terminal via semi-static downlink signaling (e.g., radio resource control (RRC) signaling) to configure a set of cyclic time-frequency resources for the terminal to downlink control/data transmissions.

B, Type 2 Grant configured: The network device sends downlink semi-static signaling to the terminal to configure cyclic time-frequency resources for transmission on the forward link, while the size and location of the time-frequency resource in each cycle is reported to the terminal by transmitting a base a downlink control information (DCI) station.

C, dynamic resource allocation: the network device allocates a time-frequency resource to a terminal for forward link transmission by transmitting DCI.

When the terminal uses the Mode 1 resource allocation method, the terminal configured as the data transmitting side supports transmitting HARQ feedback information for forward link data to the network device via a Physical Uplink Control Channel (PUCCH). For a configured Type 2 grant or dynamically scheduled time-frequency resource allocation method, PUCCH selection and configuration for transmitting HARQ feedback information for forward link data may multiplex PUCCH selection and configuration for transmitting HARQ downlink data. The PUCCH resource for transmitting the forward link HARQ data and the PUCCH resource for transmitting the downlink HARQ data are configured respectively.

For PUCCH resource configuration for HARQ forward link data, the terminal is configured with no more than four PUCCH resource sets (for ease of description, the plurality of PUCCH resource sets configured for HARQ forward link data in embodiments of the invention are referred to as PUCCH HARQ forward link data resources) . Each PUCCH resource of the forward link HARQ data PUCCH resources corresponds to a different forward link data HARQ feedback payload size. When the forward link data HARQ selects a PUCCH to transmit, a PUCCH resource set is selected from the first resource set based on the payload size of the forward link HARQ data, and one PUCCH is selected to transmit the forward link HARQ data from the PUCCH resource set based on the configured Grant Type. 2 or specifying a dynamically scheduled DCI.

For PUCCH resource configuration for downlink HARQ data transmission, the terminal is configured with no more than four PUCCH resource sets (for ease of description, the plurality of PUCCH resource sets configured for downlink data in embodiments of the invention are referred to as downlink HARQ data PUCCH resources) . Each PUCCH resource set of the downlink data PUCCH HARQ resources corresponds to a different uplink control information (UCI) payload size. When the downlink data HARQ selects a downlink data PUCCH HARQ resource for transmission, the downlink data PUCCH HARQ resource set is selected from the first resource set based on the downlink data HARQ payload size, and one from the downlink data HARQ data PUCCH resource set the communication links are selected based on the DCI's indication of downlink data transmission scheduling.

In addition, when the PUCCH resource selected for the downlink data HARQ overlaps with the PUCCH to transmit another UCI (e.g., scheduling request (SR) or channel state information (CSI)) in the time domain, the downlink data HARQ and said the other UCI is combined for transmission in one PUCCH. The PUCCH selection method includes selecting a PUCCH resource set based on a combined UCI payload size and selecting one PUCCH resource from a PUCCH resource set based on a downlink data scheduling indication from the DCI.

According to the resource allocation method described above, a situation may occur in which a PUCCH resource selected for HARQ forward link data overlaps with a PUCCH resource selected for other uplink information other than HARQ forward link data in the time domain. For example, said other uplink information may be HARQ feedback information for downlink data, scheduling request, channel state information or uplink data, and so on. In this case, the problem to be solved is how to transmit forward link feedback information (HARQ of forward link data).

Embodiments of the invention provide a transmission method in which, when a PUCCH resource for transmitting forward link feedback information overlaps with a PUCCH resource for transmitting other time domain uplink information, one of the PUCCHs for transmitting forward link feedback information and a PUCCH is transmitted. to transmit said other uplink information.

According to the invention, a PUCCH for transmitting forward link feedback information is called a first PUCCH, and an uplink physical channel for transmitting other uplink information that is not forward link feedback information is called a second uplink physical channel. The second physical uplink channel may be a PUCCH or may be a physical uplink shared channel (PUSCH, physical uplink shared channel).

In one embodiment of the invention, when the resource of the first PUCCH for transmitting forward link feedback information overlaps with the resource of the second physical uplink channel for transmitting other uplink information in the time domain, the first PUCCH is transmitted or the second physical uplink channel is transmitted.

In one embodiment of the invention, when the resource of the first PUCCH for transmitting forward link feedback information overlaps with the resource of the second physical uplink channel for transmitting other uplink information in the time domain, the first PUCCH is transmitted and the second physical uplink channel is discarded. , or the second uplink physical channel is transmitted and the first PUCCH is discarded.

Fig. 2 is a first block diagram illustrating a feedback method according to an embodiment of the invention. As shown in FIG. 2, the feedback method is applied in the terminal and includes the following.

In step S11, it is determined that the resource of the first PUCCH for transmitting forward link feedback information overlaps with the resource of the second physical uplink channel for transmitting other uplink information in the time domain.

In an embodiment of the invention, the forward link feedback information may be HARQ feedback information for the forward link data. Said other uplink information refers to other uplink information in addition to the HARQ feedback information for forward link data, which may be uplink control information, or may also be uplink data information, such as said other uplink information. The link may be HARQ feedback information for downlink data, SR, CSI report or uplink data, etc. When said other uplink information is uplink control information, the second uplink physical channel may be the second PUCCH. When said other uplink information is uplink data information, the second uplink physical channel may be the second PUSCH.

In step S12, a first PUCCH corresponding to the forward link feedback information is transmitted, or a second uplink physical channel corresponding to said other uplink information is transmitted. In an embodiment of the invention, when a PUCCH resource for transmitting forward link feedback information overlaps with a physical uplink channel resource for transmitting said other time domain uplink information, the first PUCCH is transmitted and the second physical uplink channel is not transmitted, or the second uplink physical channel is transmitted and the first PUCCH is not transmitted, so that the transmission of uplink information can be realized with little change in the uplink transmission signaling, and the network device does not need to change the signaling, so the reception of uplink data can be implemented on the basis of existing methods of data transmission.

It should be understood that the untransmitted resource of the first PUCCH or the untransmitted resource of the second uplink physical channel in an embodiment of the invention may be discarded.

The process of transmitting the first PUCCH without transmitting the second physical uplink channel or the process of transmitting the second physical uplink channel without transmitting the first PUCCH will be described below in embodiments of the invention in conjunction with actual applications.

In one embodiment of the invention, it may be decided to transmit the first PUCCH or transmit the second uplink physical channel based on the configuration information. The terminal in an embodiment of the invention may decide to transmit the first PUCCH or transmit the second uplink physical channel based on the configuration information. When the configuration information is configured to indicate the transmission of the first PUCCH, the first PUCCH is transmitted, and when the configuration information is configured to indicate the transmission of the second physical uplink channel, the second physical uplink channel is transmitted.

The configuration information used in an embodiment of the invention may be configuration information stored in the terminal, or may also be configuration information received from another communication device, which is not limited in embodiments of the invention.

For example, the forward link feedback information is HARQ of the forward link data. Said other uplink information is uplink control information (UCI). The second uplink physical channel is the second PUCCH.

When the terminal determines that the PUCCH for transmitting the UCI overlaps with the PUCCH selected for the HARQ data of the forward link in the time domain, and the configuration information indicates that the transmission of the uplink UCI is performed and the transmission of the HARQ data of the forward link is refused, the terminal decides to transmit the second PUCCH. When the terminal determines that the PUCCH for transmitting the UCI overlaps with the PUCCH selected for the HARQ data of the forward link in the time domain, and the configuration information indicates the transmission of the uplink HARQ data of the forward link, the terminal decides to transmit the first PUCCH.

In another example, the forward link feedback information is HARQ of the forward link data. Said other uplink information is uplink data. The second uplink physical channel is the second PUSCH.

When the configuration information indicates PUSCH transmission and the terminal determines that the PUSCH overlaps with the PUCCH selected for the forward link HARQ data in the time domain, the PUSCH is transmitted and the first PUCCH is not transmitted. When the configuration information indicates forward link HARQ data transmission, and the terminal determines that the PUSCH overlaps with the PUCCH selected for the forward link HARQ data in the time domain, the first PUCCH is transmitted and the PUSCH is not transmitted.

In another embodiment of the invention, the first PUCCH is transmitted and the second uplink physical channel is not transmitted based on the content of the uplink information included in said other uplink information. Alternatively, the second uplink physical channel is transmitted and the first PUCCH is not transmitted based on the content of the uplink information included in said other uplink information.

In an example where the content of uplink information included in said other uplink information may be one of CSI, SR or combined CSI and SR information, the first PUCCH is transmitted and the second physical uplink channel is not transmitted.

For example, the forward link feedback information is HARQ of the forward link data. The other uplink information mentioned is the UCI. The second uplink physical channel is the second PUCCH. When the information in the UCI is one of CSI, SR, or combined CSI and SR information, the first PUCCH is transmitted and the second uplink physical channel is not transmitted. In another example, the forward link feedback information is HARQ of the forward link data. The second uplink physical channel is the second PUSCH. When said other uplink information is one of the CSL SR or the combined CSI and SR information, the first PUCCH is transmitted and the PUSCH is not transmitted.

In another example, when said other uplink information includes uplink data and/or feedback information for downlink data, the first PUCCH is transmitted and the second uplink physical channel is not transmitted, or the second uplink physical channel is transmitted and the first PUCCH is not transmitted based on the data transmission priority corresponding to the forward link feedback information and the data transmission priority corresponding to said other uplink information. The data transfer priority may be, for example, a quality of service (QoS) priority.

In one embodiment of the invention, when the data transmission priority corresponding to said other uplink information is higher than the data transmission priority corresponding to the forward link feedback information, the second uplink physical channel is transmitted and the first PUCCH is not transmitted. When the data transmission priority corresponding to the forward link feedback information is higher than the data transmission priority corresponding to said other uplink information, the first PUCCH is transmitted and the second uplink physical channel is not transmitted.

For example, the forward link feedback information is HARQ of the forward link data. Said other uplink information is the UCI, which includes the HARQ of the downlink data. The second uplink physical channel is the second PUCCH. When the PUCCH for transmitting the UCI overlaps with the PUCCH selected for the HARQ data of the forward link in the time domain, the determination is made based on the transmission priority of the downlink data corresponding to the HARQ feedback of the downlink data and the transmission priority of the forward link data, corresponding HARQ feedback for the forward link data. If the downlink data transmission priority is higher than the forward link data transmission priority, the second PUCCH is transmitted and the first PUCCH is not transmitted, that is, the UCI is transmitted but the HARQ feedback for the forward link data is not transmitted. If the forward link data transmission priority is higher than the downlink data transmission priority, the first PUCCH is transmitted and the second PUCCH is discarded, that is, HARQ feedback is transmitted for the forward link data but no UCI is transmitted.

In another example, the forward link feedback information is HARQ of the forward link data. The second uplink physical channel is the second PUSCH. When the PUSCH overlaps with the PUCCH selected for the forward link data HARQ in the time domain, consider the data transmission priority corresponding to the uplink information included in the PUSCH and the forward link data transmission priority corresponding to the HARQ feedback for the forward link data . When the data transmission priority corresponding to the uplink information included in the PUSCH is higher than the forward link data transmission priority corresponding to the HARQ feedback for the forward link data, the PUSCH is transmitted and the first PUCCH is discarded. When the forward link data transmission priority corresponding to the HARQ feedback for the forward link data is higher than the data transmission priority corresponding to the uplink information included in the PUSCH, the first PUCCH is transmitted and the PUSCH is discarded. The data transmission priority corresponding to the uplink information included in the PUSCH may be an uplink data priority, such as an uplink-synchronization channel (UL-SCH) priority. The data transmission priority corresponding to the uplink information included in the PUSCH may also be the data transmission priority including both the uplink data and the multiplexed UCI.

In an embodiment of the invention, if the PUSCH includes only uplink data (UL-SCH), consider the uplink data transmission priority and the forward link data transmission priority corresponding to the feedback for the forward link data. In an embodiment of the invention, if the PUSCH includes both uplink data and a multiplexed UCI (combined UCI), different processing methods may be used based on whether the UCI includes HARQ feedback information for the downlink data. If the multiplexed UCI does not include HARQ feedback information for downlink data, the uplink data transmission priority and the forward link data transmission priority corresponding to the feedback for the forward link data are considered. If the multiplexed UCI includes HARQ feedback information for the downlink data, the higher of the uplink data priority and the downlink data priority corresponding to the HARQ feedback for the downlink data is compared with the forward link data transmission priority corresponding to the reverse links for forward link data.

In an embodiment of the invention, if the PUSCH includes only uplink data and the data transmission priority corresponding to the uplink data is higher than the forward link data transmission priority corresponding to the feedback for the forward link data, the PUSCH is transmitted and the first PUCCH not transmitted, that is, PUSCH is transmitted and forward link HARQ data is not transmitted. If the forward link data transmission priority corresponding to the feedback for the forward link data is higher than the data transmission priority corresponding to the uplink data, then the first PUCCH is transmitted, and the PUSCH is not discarded, that is, the HARQ of the forward link data is transmitted, a PUSCH is not transmitted.

In another embodiment, the network device may configure a preconfigured priority threshold for the terminal, and whether to transmit the first PUCCH or transmit the second uplink physical channel is determined based on the preconfigured priority threshold.

In one embodiment of the invention, the network device pre-configures the uplink-downlink data priority threshold. When the data transmission priority corresponding to said other uplink information is higher than the preconfigured uplink-downlink data priority threshold, the second uplink physical channel is transmitted and the first PUCCH is not transmitted. When the data transmission priority corresponding to said other uplink information is lower than the preconfigured uplink-downlink data priority threshold, the first PUCCH is transmitted and the second uplink physical channel is not transmitted.

In another embodiment of the invention, the network device pre-configures a forward link data priority threshold. When the data transmission priority corresponding to the forward link feedback information is higher than the preconfigured forward link data priority threshold, the first PUCCH is transmitted and the second uplink physical channel is not transmitted. When the data transmission priority corresponding to the forward link feedback information is lower than the preconfigured forward link data priority threshold, the second uplink physical channel is transmitted and the first PUCCH is not transmitted.

In another embodiment of the invention, the first PUCCH is transmitted and the second uplink physical channel is not transmitted based on the reception time of the data scheduling DCI corresponding to the forward link feedback information and the reception time of the data scheduling DCI corresponding to said other uplink information. Alternatively, the second uplink physical channel is transmitted and the first PUCCH is not transmitted based on the reception time of the data scheduling DCI corresponding to the forward link feedback information and the reception time of the data scheduling DCI corresponding to said other uplink information. When the reception time of the first data scheduling DCI corresponding to the forward link feedback information is later than the reception time of the second data scheduling DCI corresponding to said other uplink information, the first PUCCH is transmitted and the second uplink physical channel is not transmitted. When the reception time of the second data scheduling DCI corresponding to said other uplink information is later than the reception time of the first data scheduling DCI corresponding to the forward link feedback information, the second uplink physical channel is transmitted and the first PUCCH is not transmitted.

For example, the forward link feedback information is forward link HARQ data. Said other uplink information is UCI which includes HARQ feedback for downlink data. The second uplink physical channel is the second PUCCH. When the PUCCH for transmitting the UCI overlaps with the PUCCH selected for the HARQ of the forward link data in the time domain, consider the reception time of the DCI of the forward link data transmission scheduling corresponding to the HARQ feedback of the forward link data, and the reception time of the DCI of the downlink data transmission scheduling. link corresponding to the HARQ feedback for the downlink data. If the time of the second DCI corresponding to the HARQ of the downlink data is later than the time of the first DCI corresponding to the HARQ of the forward link data, the second PUCCH is transmitted and the first PUCCH is discarded, that is, the UCI is transmitted and the HARQ feedback for the forward link data communications are not transmitted.
