- D2D communication is based on SL transmission technology, which is different from the way in which communication data is received or sent through base stations in the traditional cellular system. Therefore, it has higher spectrum efficiency and lower transmission delay.
- the Internet of Vehicles system uses D2D communication (ie Direct device-to-device communication).
- the Third Generation Partnership Project (3GPP) defines two transmission modes: the first mode (also referred to as mode A) and the second mode (also referred to as mode B).
- the first mode is that the network device allocates transmission resources to the terminal device
- the second mode is that the terminal device independently selects the transmission resources.
- the transmission resources of the terminal equipment are allocated by the base station, and the terminal equipment transmits data on the side link according to the resources allocated by the base station; the base station can allocate a single transmission for the terminal equipment Resources, semi-static transmission resources can also be allocated to terminal devices.
- the terminal device selects a transmission resource in the resource pool to send data.
- NR-V2X New Radio-Vehicle to Everything
- autonomous driving needs to be supported. Therefore, higher requirements are put forward for data interaction between vehicles, such as higher throughput and lower Time delay, higher reliability, larger coverage, more flexible resource allocation, etc.
- NR-V2X broadcast transmission mode, unicast transmission mode and multicast transmission mode are supported.
- the unicast transmission mode as shown in Figure 3, there is only one terminal device at the receiving end, and unicast transmission is performed between UE1 and UE2.
- the receiving end is all terminal devices in a communication group, or all terminal devices within a certain transmission distance.
- UE1, UE2, UE3, and UE4 form a communication group, where UE1 is the terminal device at the transmitting end, used to send data, and UE2, UE3, and UE4 in the group are all at the receiving end.
- Terminal equipment used to receive data.
- the receiving end can be any terminal device.
- UE1 is the terminal device of the transmitting end for sending data
- other terminal devices around UE1, such as UE2, UE3, UE4, UE5, UE6 and UE7 is a terminal device at the receiving end for receiving data.
- a side-line feedback channel is introduced.
- the schematic diagram of the side-line feedback process is shown in Figure 6.
- the terminal device at the transmitting end sends side-line data (including the Physical Sidelink Control Channel (PSCCH) and the physical side to the terminal device at the receiving end).
- Physical Sidelink Shared Channel (PSSCH) the terminal device at the receiving end sends feedback information to the terminal device at the sending end, such as Hybrid Automatic Repeat reQuest (HARQ) feedback information;
- HARQ feedback information is carried in a side-line feedback channel, such as a physical side-link feedback channel (PSFCH).
- PSFCH physical side-link feedback channel
- side feedback can be activated or deactivated through pre-configuration information or network configuration information. If the side-line feedback is activated, the terminal device at the receiving end receives the side-line data sent by the terminal device at the transmitting end, and feeds back HARQ acknowledgement (ACK) or negative (NACK) to the terminal device at the transmitting end according to the detection result. The terminal device at the sending end sends retransmission data or sends new data according to the feedback information of the terminal device at the receiving end. If the sideline feedback is deactivated, the terminal device at the receiving end does not need to send feedback information, and the terminal device at the sending end usually sends data in a blind transmission manner. For example, the terminal device at the sending end repeatedly sends K times for each side row data, instead of deciding whether to send retransmitted data according to the feedback information of the terminal device at the receiving end.
- ACK HARQ acknowledgement
- NACK negative
- UE1 For unicast transmission and side feedback has been activated, if UE1 sends PSSCH to UE2 in time slot 2, UE2 needs to send side feedback to UE1 in time slot 7; if UE3 sends PSSCH to UE2 in time slot 3, UE2 needs to send sideline feedback to UE3 in time slot 7. Therefore, the terminal device needs to send two feedback messages in time slot 7. That is, the terminal device needs to send two side feedback channels in time slot 7. These two feedback channels are respectively Used to carry feedback information sent to UE1 and UE3.
- Method 1 The terminal device sends two side-line feedback channels at the same time: the two side-line feedback channels will share the transmission power of the terminal device; if the transmission power of the terminal device is limited, it will cause the transmission power of each side-line feedback channel to be equal Lower, which in turn reduces the performance of PSFCH.
- Method 2 The terminal device only sends one side-line feedback channel: the terminal device can select the side-line feedback channel corresponding to the side-line data with the highest priority according to the priority of the side-line data corresponding to the side-line feedback information to ensure high priority Transmission performance of side row data.
- the embodiment of the application provides a side-line feedback method.
- the side-line feedback method of the embodiment of the application can be applied to various communication systems, such as the Global System of Mobile Communication (GSM) system, and code division multiple access (GSM) system.
- Code Division Multiple Access (CDMA) system Code Division Multiple Access (CDMA) system, 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 or 5G system, etc.

- An optional processing flow of the lateral feedback method provided in the embodiment of the present application, as shown in FIG. 8, includes the following steps:
- Step S101 The first terminal device acquires first configuration information; the first configuration information is used to determine the side-line feedback mode, or the first configuration information is used to determine that the first terminal device can transmit at the same time The maximum number of side-line feedback channels.
- the first terminal device may obtain the first configuration information according to the pre-configuration information.
- the pre-configuration information may be resource pool configuration information; the first configuration information is carried in the resource pool configuration information.
- the pre-configuration information includes capability information of the first terminal device; the capability information of the first terminal device may be a capability level or a capability category of the first terminal device.
- the maximum number of lateral feedback channels that can be simultaneously transmitted by the first terminal device of different capability levels or capability categories may be different. Therefore, according to the capability information of the first terminal device, the maximum number of side feedback channels that can be simultaneously transmitted by the first terminal device corresponding to the capability information can be determined.
- the first terminal device may receive the first configuration information sent by the network device corresponding to the cell.
- the first configuration information may be carried in a broadcast message, or radio resource control (Radio Resource Control, RRC) signaling, or downlink control information (Downlink Control Information, DCI).
- RRC Radio Resource Control
- DCI Downlink Control Information
- the network device sends resources for sideline transmission to the first terminal device through System Information Block (SIB), and the first configuration information may be carried in the SIB information.
- SIB System Information Block
- the network device may configure resource pool information for the first terminal device through RRC signaling; the resource pool configuration information may include the first configuration information.
- the network device configures the sideline transmission resource for the first terminal device through the DCI; the first configuration information may be carried in the DCI.
- the first terminal device may receive the first configuration information sent by the second terminal device.
- the first configuration information may be carried in the Physical Sidelink Broadcast Channel (PSBCH, PSCCH, or PSSCH, or Physical Sidelink Broadcast Channel).
- PSBCH Physical Sidelink Broadcast Channel
- PSSCH Physical Sidelink Broadcast Channel
- the second terminal device may be a group head terminal device of the communication group where the terminal device acquiring the first configuration information is located; wherein, the group head terminal device may have Terminal equipment with functions such as resource management, resource allocation, resource scheduling or resource control.
- the first configuration information includes a first information field, and when the first information field is 1 bit, the first configuration information is used to determine a side-line feedback mode; When the information field is N bits, the first configuration information is used to determine the maximum number of side feedback channels that the first terminal device can transmit at the same time, and N is a positive integer greater than 1.
- the side-line feedback mode may at least include: the first terminal device can only transmit one side-line feedback channel at the same time; or, The first terminal device can transmit two or more side row feedback channels at the same time.
- the first terminal device can transmit two or more sideline feedback channels at the same time. It can also be understood that the first terminal device can transmit more than one sideline feedback channel at the same time, and the first terminal device can transmit more than one sideline feedback channel at the same time.
- the maximum number of side-line feedback channels that a terminal device can transmit at the same time is not limited; the first terminal device determines the number of side-line feedback channels that the first terminal device transmits based on the detected side-line data. For example, in Figure 7, if the first terminal device detects 5 side-line data in time slot 2, it includes 3 side-line data sent in broadcast mode (without sending feedback information) and 2 side-line data sent in unicast mode.
- Line data (need to send feedback information); 3 side line data is detected in time slot 3, including 2 side line data sent in broadcast mode (no need to send feedback information) and 1 side line data sent in unicast mode ( Need to send feedback information); if side row data is not detected in time slot 4, and 1 side row data sent in unicast mode is detected in time slot 5 (feedback information needs to be sent), then the first terminal device is in time slot 7
- the number of side-line feedback channels that need to be sent is 4.
