Detailed ways

In order to make the purpose, technical solutions, and advantages of the present application clearer, the implementation manners of the present application will be described in further detail below in conjunction with the accompanying drawings.

First, briefly introduce the terms involved in the embodiments of this application:

The Internet of Vehicles (Vehicle to Everything, V2X): It is the key technology of the future intelligent transportation system. It mainly studies the vehicle data transmission scheme based on the 3GPP communication protocol. V2X communication includes vehicle to vehicle (V2V) communication, vehicle to roadside infrastructure (V2I) communication, and vehicle to pedestrian (Vehicle to People, V2P) communication. V2X applications will improve driving safety, reduce congestion and vehicle energy consumption, and improve traffic efficiency.

Side Link (SideLink, SL) transmission: It is a communication method from terminal equipment to terminal equipment, which has higher spectrum efficiency and lower transmission delay. In 3GPP, two side link transmission modes are defined: mode A and mode B. As shown in (1) in Figure 1, in mode A, the transmission resources of the terminal equipment are allocated by the network equipment (such as the base station) through the downlink DL, and the terminal equipment performs on the side link according to the resources allocated by the base station. Data transmission; network equipment can allocate single transmission resources for terminal equipment (dynamic allocation), and can also allocate semi-static transmission resources for terminal equipment. As shown in (2) in Figure 1, in mode B, the terminal device selects a side row resource from the resource pool for data transmission. Specifically, the terminal device may select side resources from the resource pool by means of listening, or select side resources from the resource pool by means of random selection.

In LTE-V2X, the broadcast transmission mode is supported. In NR-V2X, unicast and multicast transmission modes are introduced. For unicast transmission, there is only one terminal at the receiving end. As shown in Figure 2, unicast transmission is carried out between User Equipment (UE1) and UE2; for multicast transmission, the receiving end is all in a multicast group. UE, or all terminals within a certain transmission distance, as shown in Figure 3. UE1, UE2, UE3, and UE4 form a multicast group, where UE1 sends data, and other UEs in the group are receiving end terminals; for broadcast transmission In this way, the receiving end is any terminal, as shown in Figure 4, where UE1 is the transmitting end terminal, and the other UEs around it are all receiving end terminals. .

Sideline configuration authorization (Configured Grant, CG)

In New Radio (NR)-V2X, mode 1 and mode 2 resource allocation methods are supported. In mode 2, the terminal autonomously selects side-line resources in the resource pool for side-line transmission, that is, mode B shown in Figure 1; in mode 1, the network allocates side-line resources to the terminal, that is, mode A shown in Figure 1. Specifically, the network device may allocate side-line resources to the terminal device by means of dynamic scheduling (Dynamic Scheduling); or the network device may allocate the side-line configuration authorization (SL CG) side-line resources to the terminal device. For CG resource allocation methods, there are mainly two configuration authorization methods: type-1 configured grant (the first type of configuration authorization) and type-2 configured grant (the second type of configuration authorization)

The first type of configuration authorization: the network equipment configures sideline resources for the terminal equipment through Radio Resource Control (RRC) signaling. The RRC signaling configuration includes time domain resources, frequency domain resources, and demodulation reference signals (Demodulation Reference Signal, DMRS), modulation and coding scheme (Modulation and Coding Scheme, MCS), including all side resources and transmission parameters. After the UE receives the high-level parameters, it can immediately use the configured transmission parameters to perform side-line transmission on the configured time-frequency resources.

The second type of configuration authorization: adopts a two-step resource configuration method, that is, RRC + Downlink Control Information (Downlink Control Informatica, DCI); first, the RRC signaling configuration includes the period of time-frequency resources, and hybrid automatic repeat reQuest (Hybrid Automatic Repeat reQuest). , HARQ) the number of processes and other side-line resources and transmission parameters, and then the DCI activates the second type of configuration authorized transmission, and at the same time configures other side-line resources including time domain resources, frequency domain resources, MCS, etc. Transmission parameters. When the UE receives the RRC signaling, it cannot immediately use the resources and parameters configured by the higher-layer parameters for side-line transmission, but must wait for the corresponding DCI to be activated and configure other resources and transmission parameters before performing side-line transmission. In addition, the network device can deactivate the configuration transmission through the DCI, and when the terminal device receives the deactivated DCI, it can no longer use the side-line resource for side-line transmission.

If the network device allocates the second type of configuration authorization sideline resource to the terminal device, when the terminal device has sideline data to be transmitted, it can directly use the sideline resource for transmission without sending a scheduling request to the network device (Scheduling Request, SR) / Buffer Status Report (Scheduling Request, BSR) request side-line resources, thereby reducing delay.

Sidelink Feedback Channel (Physical Sidelink Feedback Channel, PSFCH):

In NR-V2X, in order to improve reliability, a side-line feedback channel is introduced. For example, for unicast transmission, the sending end terminal sends sideline data (including PSCCH and PSSCH) to the receiving end terminal, the receiving end terminal sends HARQ feedback information to the sending end terminal, and the sending end terminal determines whether it is necessary according to the feedback information of the receiving end terminal. Perform a retransmission. The HARQ feedback information is carried in the side feedback channel. For example, the HARQ feedback information includes an acknowledgement ACK or a negative acknowledgement NACK.

The side-line feedback can be activated or deactivated through the pre-configuration information or network device configuration information. If the side-line feedback is activated, the receiving end terminal receives the side line data sent by the sending end terminal, and feeds back HARQ ACK or the sending end according to the detection result. NACK, the sending end terminal decides to send retransmission data or new data according to the feedback information of the receiving end; if the sideline feedback is deactivated, the receiving end terminal does not need to send feedback information. The sending end terminal usually sends data by blind retransmission, for example , The sending end terminal repeatedly sends K times for each side row data, instead of deciding whether to send retransmitted data according to the feedback information of the receiving end terminal.

In mode 1, the network device allocates side-line resources to the terminal device. If the sending-end terminal uses this resource to transmit side-line data that supports side-line feedback, the receiving end sends the side-line feedback information to the sending end, and the sending end feeds back the side-line feedback information. The information is reported to the network device, and the network device decides whether to allocate retransmission resources according to the side feedback information reported by the sender, as shown in Figure 5.

Specifically, the network device may allocate a PUCCH resource to the terminal device, and the PUCCH side resource is used for the sending terminal terminal to report side feedback information to the network device.

As shown in Figure 6, UE1 is the sender UE, UE2 is the receiver UE, and gNB allocates sideline resources for UE1 and PUCCH sideline resources. UE1 sends the sideline to UE2 on the sideline resources allocated by the network equipment. Data PSCCH/PSSCH, UE2 sends side-line feedback information to UE1 based on the detection result of side-line data (for example, sending HARQ-ACK on PSFCH), which is used to indicate whether the side-line data is received correctly, and UE1 will send the side-line feedback information It is reported to the network device through the PUCCH, and the network device decides whether to allocate retransmission resources for the UE1 according to the side feedback information reported by the UE1.

However, after the network device allocates the side row resources to the terminal device, the terminal device decides which side row data to use the side row resource to transmit. For example, the first side row data can be transmitted, and the corresponding delay requirement is 10ms; or When transmitting the second side line data, the corresponding delay requirement is 100ms, but the network does not know the type of the side line data. When the network receives the NACK reported by the terminal and allocates retransmission resources for the terminal, it may exceed the time of the terminal. Delay demand. How to prevent the network from assigning invalid side transmission resources to the terminal is a problem that needs to be solved

FIG. 7 shows a block diagram of a communication system supporting sideline transmission provided by an exemplary embodiment of the present application. The communication system may be a schematic diagram of a non-roaming 5G system architecture (Non-roaming 5G system architecture), and the system architecture may be applied to a vehicle to everything (V2X) service using D2D technology.

The system architecture includes a data network (Data Network, DN), and the data network is provided with a V2X application server (Application Server) required for a V2X service. The system architecture also includes the 5G core network. The network functions of the 5G core network include: Unified Data Management (UDM), Policy Control Function (PCF), Network Exposure Function (NEF), Application Function (AF), Unified Data Repository (UDR), Access and Mobility Management Function (AMF), Session Management Function (SMF), and user interface Function (User Plane Function, UPF).

The system architecture also includes: a radio access network (New Generation-Radio Access Network, NG-RAN) and four terminal devices (namely, terminal device 1 to terminal device 4) shown by way of example, wherein each terminal device is V2X application (Application) is installed. One or more access network devices, such as base stations (gNB), are provided in the wireless access network. The terminal equipment performs uplink transmission to the access network equipment.

In this system architecture, the data network and the user plane function in the 5G core network are connected through the N6 reference point (Reference Point), the V2X application server is connected with the V2X application in the terminal device through the V1 reference point; the wireless access network is connected with the 5G core network The AMF function and UPF function in the connection, the wireless access network is connected to the terminal device 1 and the terminal device 5 through the Uu reference point; multiple terminal devices use the PC5 reference point for sideline transmission, and multiple V2X applications pass through V5 reference point connection. The above-mentioned reference point may also be referred to as an "interface".

Fig. 8 shows a flowchart of a resource selection method provided by an exemplary embodiment of the present application. In this embodiment, the method is applied to the communication system shown in FIG. 7 as an example. The method includes:

Step 102: The terminal device sends uplink information to the network device when the time domain position of the transmission resource exceeds the time domain position corresponding to the time delay requirement of the sideline data;

The terminal device determines that the time domain position of the transmission resource exceeds the time domain position corresponding to the time delay requirement of the side line data, and sends the uplink information to the network device. Among them, the uplink information is used to terminate the network device's allocation of side-line data retransmission resources to the terminal device.

Transmission resources are resources allocated by network equipment to terminal equipment. The transmission resource includes at least one of a side row resource and an uplink resource. Among them, the side row resource is used to send the initial transmission and/or retransmission of the side row data, and the uplink resource is used to send the receiving feedback (ACK or NACK) of the side row data. The side-line data is the data that the terminal device decides to transmit on the side-line resource.

Among them, the time domain location corresponding to the time delay requirement refers to the time indicated by "the service arrival time of the side line data + the time delay requirement".

Optionally, the uplink information is information carried on uplink resources, and the uplink resources may be resources on a physical uplink control channel (Physical Uplink Control Channel, PUCCH). The uplink information is information corresponding to the side row resource, for example, the time interval between the PUCCH transmission resource and the side row transmission resource is determined according to the network configuration information.

Optionally, the uplink resource used to carry the uplink information is allocated by the network device to the terminal device.

Step 104: The network device receives the uplink information from the terminal device;

The network device receives the uplink information sent by the terminal device on the uplink resource.

Step 106: The network device terminates allocating sidestream data retransmission resources to the terminal device according to the uplink information.

After receiving the uplink information corresponding to the side row resource, the network device terminates allocating the side row data retransmission resource to the terminal device.

Exemplarily referring to FIG. 9, at time n, terminal device A has sideline data arriving, and the sideline data needs to be transmitted. Assuming that the delay requirement corresponding to the side line data is 10 milliseconds (ms), that is, the packet delay budget (PDB) of the side line data is 10 ms, so the terminal device A sends the SR/BSR to the network device to apply for the side The network device allocates 3 side row resources and 1 PUCCH resource to the terminal device A. The time domain positions of the 3 side row resources correspond to n+6ms, n+9ms, and n+12ms respectively. The terminal device A uses the first One side line resource (n+6ms) sends the initial transmission of the side line data, and the second side line resource (n+9ms) is used to send the retransmission of the side line data. If terminal device A receives the NACK sent by terminal device B, terminal device A should send a retransmission of the side line data, but the time domain position n+12ms of the third side line resource has exceeded the time delay of the side line data Therefore, the terminal device A will not use the sideline resource (n+12ms) to send retransmissions, and report uplink information to the network device on the PUCCH resource, so as to terminate the network device's scheduling of retransmission resources for the terminal device A.

Exemplarily referring to FIG. 10, at time n, terminal device A has sideline data arriving, and the sideline data needs to be transmitted. Assuming that the delay requirement corresponding to the side line data is 15 milliseconds (ms), that is, the packet delay budget (PDB) of the side line data is 10 ms, so the terminal device A sends an SR/BSR to the network device to apply for the side The network device allocates 3 side row resources and 1 PUCCH resource to terminal device A. The time domain positions of the 3 side row resources correspond to n+6ms, n+9ms, and n+12 ms, respectively. The domain position corresponds to n+16ms. Terminal device A uses the first side row resource (n+6ms) to send the initial transmission of side row data, and uses the second side row resource (n+9ms) and the third side row resource ( n+12ms) Retransmission of line data on the sending side. If terminal device A receives the NACK sent by terminal device B, terminal device A should send a retransmission of the sideline data, but because the time domain position of the PUCCH resource has exceeded the delay requirement of the sideline data, even if the retransmission is allocated again Resources are also invalid retransmission resources. Therefore, the terminal device A will not use the PUCCH resource to report a NACK to the network device, but instead use the PUCCH resource to report uplink information to the network device, so as to terminate the network device's scheduling of retransmission resources for the terminal device A.

In summary, the resource selection method provided in this embodiment sends uplink information to the network device when the time domain position of the transmission resource exceeds the time domain position corresponding to the delay requirement of the sideline data. The information is used to terminate the network device's allocation of side-line data retransmission resources to the terminal device, so that when the side-line resource allocated by the network device does not meet the service delay requirements, there is no need to continue to allocate retransmission resources to the terminal device, avoiding invalidity The allocation of retransmission resources reduces the waste of communication resources.

Illustratively, there are at least two implementation manners for uplink information: 1. Implementation using ACK; 2. Implementation using the first sequence. The following uses different embodiments to illustrate.

For the first implementation manner of uplink information, refer to the following embodiment:

Step 200: The network device allocates transmission resources to the terminal device;

When there is side data in the terminal device that needs to be sent, the terminal device sends an SR or BSR to the network device. The network device receives the SR or BSR sent by the terminal device, and dynamically allocates transmission resources to the terminal device according to the SR or BSR.

Exemplarily, the transmission resource includes at least one of a side row resource and an uplink resource. In this embodiment, the transmission resources include side-line resources and uplink resources as an example for illustration. Among them, the side row resource is used to send the initial transmission and/or retransmission of the side row data, and the uplink resource is used to send the receiving feedback (ACK or NACK) of the side row data. The side-line data is the data that the terminal device decides to transmit on the side-line resource.

Step 202: The terminal device sends an ACK to the network device when the time domain position of the transmission resource exceeds the time domain position corresponding to the delay requirement of the sideline data.

If the terminal device determines that the time domain position of the transmission resource exceeds the time domain position corresponding to the delay requirement of the sideline data, it sends an ACK to the network device. Optionally, if the terminal device determines that the time domain location of all or part of the transmission resources exceeds the time domain location corresponding to the delay requirement of the sideline data, it sends an ACK to the network device.

Optionally, when the terminal device determines that the time-domain position of the side-line resource exceeds the time-domain position corresponding to the delay requirement of the side-line data, it does not matter whether the side-line feedback information sent by the receiving end terminal is ACK or NACK. Send an ACK to the network device.

The side resource is the resource allocated by the network device to the terminal device. Uplink resources are also resources allocated by network equipment terminal equipment.

The side-line data is the data that the terminal device decides to transmit on the side-line resource. The time domain location corresponding to the time delay requirement of the side line data refers to the time indicated by "the service arrival time of the side line data + the time delay requirement".

Optionally, ACK is feedback information corresponding to side row resources, and ACK is information carried on PUCCH. The uplink information is information corresponding to the side row resources.

The upper line resource is the PUCCH resource as an example, and the PUCCH resource used to carry the uplink information is allocated by the network device to the terminal device. The ACK is information corresponding to the side row resource. Optionally, the PUCCH resource used to carry the ACK is allocated by the network device to the terminal device.

Step 204: The network device receives the ACK from the terminal device after allocating side resources to the terminal device;

The network device receives the ACK sent by the terminal device on the PUCCH resource.

Step 206: The network device terminates allocating side-line data retransmission resources to the terminal device according to the ACK.

After receiving the ACK corresponding to the side row resource, the network device terminates allocating side row data retransmission resources to the terminal device

In summary, the resource selection method provided in this embodiment sends an ACK to the network device when the time domain position of the transmission resource exceeds the time domain position corresponding to the delay requirement of the sideline data, and the ACK is used When terminating the network device’s allocation of side-line data retransmission resources to the terminal device, so that when the side-line resource allocated by the network device does not meet the service delay requirements, there is no need to continue to allocate retransmission resources to the terminal device, thereby avoiding invalid retransmission. The allocation of transmission resources reduces the waste of communication resources.

Step 300: The network device allocates transmission resources to the terminal device;

Step 302: The terminal device sends instruction information to the network device when the time domain location of the sideline resource exceeds the time domain location corresponding to the time delay requirement of the sideline data.

Optionally, if the terminal device determines that the time domain location of all or part of the transmission resources exceeds the time domain location corresponding to the delay requirement of the sideline data, it sends the instruction information to the network device.

Optionally, the indication information is used to indicate that the time domain position corresponding to all or part of the side row resources exceeds the time domain position corresponding to the delay requirement of the side row data.

Optionally, when the terminal device determines that the time-domain position of the transmission resource exceeds the time-domain position corresponding to the time delay requirement of the side-line data, regardless of whether the side-line feedback information sent by the receiving-end terminal device is ACK or NACK, it is sent to The network device sends the instruction information.

The side resource is the resource allocated by the network device to the terminal device.

Optionally, the indication information includes a first sequence, and the first sequence is a bit sequence different from ACK/NACK feedback. The first sequence is determined according to at least one of the following information: the identity of the terminal device and the cell identity.

Optionally, the indication information is information carried on uplink resources (PUCCH resources). The instruction information is information corresponding to the side row resource.

Optionally, the PUCCH resource used to carry the indication information is allocated by the network device to the terminal device.

Step 304: The network device receives the instruction information from the terminal device.

The network device receives the instruction information sent by the terminal device on the PUCCH resource.

Step 306: The network device terminates allocating side-line data retransmission resources to the terminal device according to the instruction information.

After receiving the instruction information corresponding to the side row resource, the network device terminates allocating the side row data retransmission resource to the terminal device.

In summary, the resource selection method provided in this embodiment sends instruction information to the network device when the time domain location of the sideline resource exceeds the time domain location corresponding to the delay requirement of the sideline data. The indication information is used to terminate the network device's allocation of side-line data retransmission resources to the terminal device, so that when the side-line resource allocated by the network device does not meet the service delay requirements, there is no need to continue to allocate retransmission resources to the terminal device, which avoids The allocation of invalid retransmission resources reduces the waste of communication resources.

FIG. 13 shows a flowchart of a resource allocation method provided by another exemplary embodiment of the present application. In this embodiment, the method is applied to the communication system shown in FIG. 7 as an example for illustration. The method includes:
