Description

A method and device for sending or receiving information

This application claims the priority of the Chinese patent application filed with the State Intellectual Property Office on August 29, 2023, with application number 202311101878.X and application name “A method and device for sending or receiving information”, the entire contents of which are incorporated by reference in this application.

Technical Field

The embodiments of the present application relate to the field of communications, and more specifically, to a method and device for sending or receiving information.

Background Art

In the process of the evolution of the fifth generation mobile communication system (5G) to 5G-advanced (5G-A) technology, communication and perception integration technology is considered to be one of the key technologies that can expand the business capabilities of mobile communication networks. The core idea of this technology is to add perception capabilities to the mobile communication network and build the ability to detect, track and image the target, so that the communication and perception capabilities can be integrated into one network to achieve harmonious coexistence and even mutual benefit.

Perception can usually be divided into two types based on the mode: single-station perception and dual-station perception. In single-station perception, the transmitter and receiver of the perception signal are the same device. From the perspective of the perception signal process, the perception site must both send the perception signal and receive the signal reflected by the perception signal on the target surface. Therefore, the single-station perception mode is also called the self-transmitting and self-receiving mode. For dual-station perception, the transmitter and receiver of the perception signal are two different devices. From the perspective of the perception signal process, after the perception site A sends the perception signal, the signal reflected by the signal on the target surface is received by the perception site B. Therefore, the dual-station perception mode is also called the A-transmitting and B-receiving mode.

However, other devices in the system cannot know whether the sensing signal is single-station sensing or dual-station sensing, resulting in other devices being unable to accurately receive the sensing signal.

In order to facilitate understanding of the technical solutions of the embodiments of the present application, a brief introduction to the relevant technologies and terms of the present application is first given.

1. Technical principles of perception.

There are some differences between the technical principles of perception and communication. Communication is when the transmitter modulates information on radio waves and sends it to the receiver, and the receiver demodulates the signal carried on the radio waves to obtain information. Perception requires the transmitter to send radio waves in a specific direction. When the radio waves hit the surface of the target, reflected radio waves are formed. The receiver receives and processes the reflected radio waves to obtain information such as the location, speed and type of the target.

Exemplarily, the communication and perception of the embodiment of the present application are multiplexed in a time division manner, and Figure 1 is a schematic diagram of the configuration of a perception symbol and a communication symbol. As shown in Figure 1, the network device configures some time domain symbols in the downlink time period as symbols that carry perception signals (which can be referred to as perception symbols for short). Considering that some network devices need to receive perception signals, and the front downlink communication signal will interfere with the subsequent perception signal, the network device reserves at least one symbol (which can be referred to as a reserved symbol) before the perception symbol during configuration to avoid interference of communication with perception.

2. Wireless communication air interface technology.

In wireless communication systems, communications can be divided into different types according to the types of sending nodes and receiving nodes. Generally, the transmission of information from a network device to a terminal device is called downlink communication, and the transmission of information from a terminal device to a network device is called uplink communication. In the long term evolution (LTE)/long term evolution advanced (LTE-A) communication system and the new rat (NR) system, according to the different duplex modes, they can be mainly divided into frequency division duplex (FDD) mode and time division duplex (TDD) mode. For wireless communication systems operating in TDD mode, the downlink carrier and uplink carrier of the system are carriers of the same carrier frequency. The multiple access method usually adopts the orthogonal frequency division multiplexing access (OFDMA) method. The main feature of the orthogonal frequency division multiplexing access method is that the transmission resources are divided into mutually orthogonal time-frequency resource elements (RE). The signals sent by the transmitter are carried on the RE and transmitted to the receiver. Since different REs are orthogonal to each other, the receiver can receive the signal sent on each RE separately.

For a time division duplex (TDD) carrier, time slot types include downlink time slots (D time slots), uplink time slots (U time slots) and special time slots (S time slots), where all symbols in downlink time slots are used for downlink communication, all symbols in uplink time slots are used for uplink communication, and special time slots include both symbols for downlink communication and symbols for uplink communication.

Fig. 2 is a schematic diagram of the system architecture of an embodiment of the present application.

FIG4 is a schematic diagram of a method for sending or receiving information provided in an embodiment of the present application. The method is illustrated by taking the interaction between the first node and the second node as an example. Of course, the subject that executes the action of the first node in the method may also be a device/module in the first node, such as a chip, a processor, a processing unit, etc. in the first node; the subject that executes the action of the second node in the method may also be a device/module in the second node, such as a chip, a processor, a processing unit, etc. in the second node, which is not specifically limited in the embodiment of the present application.

For example, the processing performed by a network device may be divided into executions by at least one of a CU, a DU, and a RU. In an embodiment of the present application, the first node may be a network device, and the second node may be a network device or a terminal device. Exemplarily, as shown in FIG4, the method 400 for sending or receiving information provided in an embodiment of the present application includes:

S410: The first node determines a type of a first time unit carrying a perception signal in a first time period.

In this embodiment of the present application, the type of the first time unit may include at least one of the following:

The same network device sends a sensing signal and receives an echo signal of the sensing signal;

The network device sends a perception signal, and the terminal device receives the perception signal;

The terminal device sends a perception signal, and the network device receives the perception signal.

It should be understood that the above-mentioned network devices and terminal devices can be a general term; the above-mentioned first network device and the second network device do not specifically refer to a certain network device and do not constitute a limitation, but are only for distinguishing the first network device and the second network device as different network devices; the above-mentioned first terminal device and the second terminal device do not specifically refer to a certain terminal device and do not constitute a limitation, but are only for distinguishing the first terminal device and the second terminal device as different terminal devices.

In a possible implementation, in an embodiment of the present application, the position of the first time unit satisfies that the adjacent previous time unit is used for uplink communication, and/or the adjacent subsequent time unit is used for downlink communication. This solution allows the first node to configure the first time unit without reserving at least one symbol before the first time unit to avoid interference of communication on perception, thereby saving resources and improving spectrum utilization.

FIG5 is a schematic diagram of a possible frame structure. As shown in FIG5, exemplarily, the first time unit is a first symbol, the first symbol may be an orthogonal frequency division multiplexing (OFDM) symbol, the first symbol is located in a downlink time slot D, the downlink time slot D is located in a first time length, and the time slots included in the first time length are DSDSU, S is a mixed time slot, and U is an uplink time slot.

In the embodiment of the present application, the first time unit may be located in the downlink time slot D in the frame structure shown in Figure 5 and Figure 6. Using the frame structure shown in Figure 5 or Figure 6 can ensure that the previous time unit adjacent to the first time unit is used for uplink communication.

In an embodiment of the present application, the first node determines the type of the first time unit that carries the perception signal in the first time period; the first node determines the configuration of the first time unit that carries the perception signal in the first time period, wherein the configuration of the first time unit includes the type of the first time unit.

Optionally, the configuration of the first time unit also includes location information of the first time unit. The location information of the first time unit includes location information of the first time period in which the first time unit is located and location information of each first time unit in the first time period in which the first time unit is located. It should be understood that the first time unit is a sub-time unit in the first time period in which the first time unit is located.

In one possible implementation, the position information of the first time unit in the first time period where the first time unit is located may include the position information of each first time unit; in another possible implementation, the position information of the first time unit in the first time period where the first time unit is located may include the position information of the first first time unit in the first time period and the number of first time units.

Exemplarily, the number of first time units in the first time period where the first time unit is located can be one or more, wherein the first time unit can occupy the first N positions in the first time period where the first time unit is located, and N is less than or equal to the number of time units included in the first time period where the first time unit is located. The embodiments of the present application do not limit this.

For example, the first time unit may be a symbol used to carry a perception signal. If the first time period in which the first time unit is located has at least one time slot, the symbol used to carry the perception signal may occupy the first N symbols of the time slot in which it is located. This embodiment of the present application is not limited to this.

It should be noted that the embodiments of the present application only exemplarily provide two methods for determining the position of the first time unit, and the embodiments of the present application do not limit the method for determining the position of the first time unit in the first time period in which the first time unit is located.

S420: The first node sends first indication information to the second node. Correspondingly, the second node receives the first indication information from the first node.

In an embodiment of the present application, the first indication information may be carried in a broadcast message, or the first indication information may be carried in a system message, or the first indication information may be carried in downlink control information (DCI), and the embodiment of the present application does not limit this.

In this embodiment of the present application, the first indication information indicates the type of the first time unit.

In a possible implementation manner, the first indication information may indicate that the type of the first time unit is one of a first type set.

In a possible implementation, the first type set includes:

The same network device sends a sensing signal and receives an echo signal of the sensing signal;

The first network device sends a perception signal, and the second network device receives the perception signal, wherein the first network device and the second network device are different network devices;

The same terminal device sends a sensing signal and receives an echo signal of the sensing signal;

The first terminal device sends a perception signal, and the second terminal device receives the perception signal, wherein the first terminal device and the second terminal device are different terminal devices;

The network device sends a perception signal, and the terminal device receives the perception signal;

The terminal device sends a perception signal, and the network device receives the perception signal.

In other words, in an embodiment of the present application, the first node may indicate, through a field corresponding to the first indication information, that the type of the first time unit is one of the six types included in the above-mentioned first type set.

In another possible implementation, the first type set includes:

The network device sends a perception signal, and the network device receives an echo signal of the perception signal; wherein the network device sending the perception signal and the network device receiving the echo signal of the perception signal may be the same network device or different network devices, which is not limited in the embodiment of the present application;

The network device sends a perception signal, and the terminal device receives the perception signal;

The terminal device sends a perception signal, and the network device receives the perception signal;

The terminal device sends a perception signal, and the terminal device receives the perception signal; wherein, the terminal device that sends the perception signal and the terminal device that receives the echo signal of the perception signal can be the same terminal device or different terminal devices, and the embodiments of the present application do not limit this.

In other words, in an embodiment of the present application, the first node can indicate through the field corresponding to the first indication information that the type of the first time unit is one of the four types included in the above-mentioned first type set. For example, when it is necessary to indicate that the type of the first time unit is that the same network device sends a perception signal and receives an echo signal of the perception signal, and/or that the first network device sends a perception signal and the second network device receives the perception signal, the field corresponding to the first indication information can be used to indicate that the type of the first time unit is that the network device sends a perception signal and the network device receives an echo signal of the perception signal. Since the number of types indicated by the first type set is reduced, this method can save resource overhead of the first indication information.

In another possible implementation, the first type set includes:

The network device sends a perception signal, and the network device or the terminal device receives the perception signal or the echo signal of the perception signal; wherein the network device sending the perception signal and the network device receiving the echo signal of the perception signal may be the same network device or different network devices, which is not limited in the embodiment of the present application;

The terminal device sends a perception signal, and the network device or the terminal device receives the perception signal or the echo signal of the perception signal; wherein, the terminal device sending the perception signal and the terminal device receiving the echo signal of the perception signal can be the same terminal device or different terminal devices, and the embodiments of the present application do not limit this.

In other words, in an embodiment of the present application, the first node can indicate through the field corresponding to the first indication information that the type of the first time unit is one of the two types included in the above-mentioned first type set. For example, when it is necessary to indicate that the type of the first time unit is that the same network device sends a perception signal and receives an echo signal of the perception signal, and/or that the first network device sends a perception signal and the second network device receives the perception signal, and/or that the network device sends perception information and the terminal device receives the perception information, the field corresponding to the first indication information can be used to indicate that the type of the first time unit is that the network device sends a perception signal and the network device or the terminal device receives the perception signal or the echo signal of the perception signal. Since the number of types indicated by the first type set is reduced, this method can save resource overhead of the first indication information.

In another possible implementation, the first type set includes:

The network device sends a perception signal, and the network device receives an echo signal of the perception signal; wherein the network device sending the perception signal and the network device receiving the echo signal of the perception signal may be the same network device or different network devices, which is not limited in the embodiment of the present application;

The network device sends a perception signal, and the terminal device receives the perception signal;

The terminal device sends a perception signal, and the network device receives the perception signal.

In other words, in an embodiment of the present application, the first node can indicate through the field corresponding to the first indication information that the type of the first time unit is one of the three types included in the above-mentioned first type set. For example, when the requirement indicates that the type of the first time unit is that the same network device sends a perception signal and receives an echo signal of the perception signal, and/or that the first network device sends a perception signal and the second network device receives the perception signal, the field corresponding to the first indication information can be used to indicate that the type of the first time unit is that the network device sends a perception signal and the network device receives an echo signal of the perception signal. Since the number of types indicated by the first type set is reduced, this method can save resource overhead of the first indication information.

In another possible implementation manner, the first indication information may indicate that the type of the first time unit is multiple types in a first type set.

Optionally, in an embodiment of the present application, when the first indication information indicates a plurality of types of first time units, the first indication information is further used to indicate a duration corresponding to each type of the first time unit.

Exemplarily, the field corresponding to the first indication information may include three fields, which are used to indicate two types and corresponding time. The durations corresponding to the two types are the same, and only one field is needed to indicate the duration. It should be understood that the second node can receive the perception signal carried on the first time unit of one type in the first T1 duration, and receive the perception signal carried on the first time unit of another type in the second T1 duration according to the three fields corresponding to the first indication information.

Alternatively, illustratively, the field corresponding to the first indication information may include four fields, which are respectively used to indicate two types and durations T1 and T2 corresponding to each type. It should be understood that the second node may receive the perception signal carried on the first time unit of the type corresponding to the T1 duration within the T1 duration, and receive the perception signal carried on the first time unit of the type corresponding to the T2 duration within the T2 duration according to the four fields corresponding to the first indication information.

Optionally, in an embodiment of the present application, the first node changes the type of the first time unit and may resend the first indication information to the second node once, which is not specifically limited in the embodiment of the present application.

Optionally, in an embodiment of the present application, the first indication information is also used to indicate the position of the first time unit.

Exemplarily, the field corresponding to the first indication information may also include a first field and a second field, the first field is used to indicate the position of the first time period in which the first time unit is located, and the second field is used to indicate the position of the first time unit on the time unit in which the first time unit is located. For example, the first time unit is a symbol carrying a perception signal, the first time period in which the first time unit is located is a time slot, the first field is {1,3}, which is used to indicate that the symbol carrying the perception signal is located in the first time slot and the third time slot; the second field is {2,3}, which indicates that the number of symbols carrying the perception signal included in the first time slot is 2, and the number of symbols carrying the perception signal included in the third time slot is 3. Or for example, the first time unit is a symbol carrying a perception signal, the first time period in which the first time unit is located is a time slot, and the first field is {1,3}, which is used to indicate that the symbol carrying the perception signal is located in the 1st time slot and the 3rd time slot; the second field is {1,2; 1,2,3}, indicating that the symbol carrying the perception signal in the 1st time slot is the 1st and 2nd symbols in the time slot, and the symbol carrying the perception signal in the 3rd time slot is the 1st, 2nd, and 3rd symbols in the time slot. The embodiment of the present application is not limited to this.

In the embodiment of the present application, the first indication information simultaneously indicates the position of the first time unit and the type of the first time unit at the corresponding position, which can enable the second node to receive the perception signal more flexibly.

S430: The second node receives the perception signal according to the first indication information.

In an embodiment of the present application, the second node may receive the perception signal according to the first indication information. It should be understood that the perception signal carried on the first time unit is not necessarily sent by the first node to the second node, but due to the characteristics of perception, the second node may still receive the perception signal carried on the first time unit according to the first indication information. The embodiment of the present application does not limit this.

In the information sending or receiving method provided in the embodiment of the present application, the first node determines the type of the first time unit carrying the perception signal in the first time period, and sends indication information indicating the type of the first time unit to the second node, so that the second node can receive the perception signal according to the type of the first time unit indicated by the first indication information. Further, the position of the first time unit satisfies that the adjacent previous time unit is used for uplink communication, and/or the adjacent next time unit is used for downlink communication, so that when the first node configures the first time unit, there is no need to reserve a time unit before the first time unit to avoid interference, which can save resource overhead and improve spectrum utilization. Furthermore, the first indication information is also used to indicate the position of the first time unit, so that the second node can receive the perception signal carried by the first time unit according to the position of the first time unit indicated by the first indication information and the type of the first time unit at the corresponding position, which is more flexible.
