One terminal device can communicate directly with another terminal device without being forwarded by network devices. Therefore, it has higher spectrum efficiency and lower transmission latency.

[0003] In V2X communication, the terminal device can request the network device to configure the sidelink transmission resource and send data on the sidelink transmission resource. The network device can configure the sidelink transmission resource for the terminal device by configuring the authorization information. When the terminal device supports the sidelink feedback, the configuration authorization information can also configure the uplink transmission resource for the terminal device. The terminal device can forward the feedback information of the sidelink to the network device through the uplink transmission resource, so that the network device can determine whether to configure the retransmission resource of the sidelink; when the terminal device does not support the sidelink feedback, the network device does not need to configure the uplink transmission resource for the terminal device.

[0025] The following will describe the technical solutions in the embodiments of the present application in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0026] Figure 1 A schematic diagram of a communication system 100 applicable to an embodiment of the present application is shown.

[0027] The system 100 includes a network device 110, a terminal device 121, and a terminal device 122. The terminal device 121 and the terminal device 122 may be vehicles with communication functions, vehicle-mounted electronic systems, mobile phones, wearable electronic devices, or other communication devices that execute the V2X protocol.

[0028] The network device 110 can be an evolutionary Node B (eNB) in an LTE system, or a base station (gNB) in a 5G communication system. The above network devices are only examples. The network device 110 can also be a relay station, an access point, a vehicle-mounted device, a wearable device, and other types of devices.

[0029] Before transmitting data via the sidelink, the terminal device 121 and the terminal device 122 may determine the sidelink transmission resource through the instruction of the network device 110. The terminal device 121 and the terminal device 122 may also determine the sidelink transmission resource without the instruction of the network device 110.

[0030] The above two examples are two transmission modes of sidelink communication, centralized scheduling transmission mode (also called mode 1) and distributed transmission mode (also called mode 2). The following is a brief introduction to the two transmission modes:

[0031] Centralized scheduling transmission mode: In this mode, the terminal device sends V2X data according to the resources allocated by the network device. Since the resources of the terminal device are uniformly allocated by the network device, the situation where adjacent terminal devices are allocated the same resources will not occur. The centralized scheduling transmission mode has better transmission reliability. However, due to the need for interactive signaling between the terminal device and the network device, the transmission delay of sending data using the centralized scheduling transmission mode is longer than that of the distributed transmission mode.

[0032] Distributed transmission mode: In scenarios with network coverage, network equipment can configure resource pools for terminal devices through system information blocks (SIB) or radio resource control (RRC) signaling. When terminal devices send V2X data, they can autonomously obtain part of the resources from the resource pool to send data through random selection, based on a listening reservation mechanism, or based on a partial listening reservation mechanism. In scenarios without network coverage, terminal devices autonomously obtain part of the resources from the resource pool configured by pre-configuration information to send data. The pre-configuration information can be information that is configured inside the terminal device when it leaves the factory, or it can be information that is pre-configured by the network device and stored inside the terminal device. Since terminal devices can autonomously select resources, different terminal devices may select the same resources to send data. Therefore, compared with the centralized scheduling transmission mode, the reliability of sending data using the distributed transmission mode is lower.

[0033] The communication system 100 is only an example, and the communication system applicable to the embodiments of the present application is not limited thereto.

[0034] In some cases, the terminal device of the sidelink needs to send uplink data. For example, after the transmitting end sends the sidelink data to the receiving end, the receiving end receives feedback information indicating the reception status of the sidelink data; if the feedback information indicates that the sidelink data reception fails, the transmitting end can send the feedback information to the network device so that the network device can allocate retransmission resources for the sidelink data.

[0035] In order to reduce the transmission delay of side traffic data, the V2X communication system introduces a configuration authorization transmission method, which mainly includes the following two methods.

[0036] Type-1 configured grant: The network device configures the sidelink transmission resources for the terminal device through RRC signaling. The content of the RRC signaling configuration includes the transmission resources and transmission parameters required by the terminal for sidelink transmission, such as time domain resources, frequency domain resources, demodulation reference signal information, etc. When the terminal device receives the RRC signaling, it can immediately use the sidelink transmission resources configured by the RRC signaling to send sidelink data.

[0037] Type-2 configured grant: First, some sidelink transmission resources and transmission parameters are configured by RRC signaling. Then, the transmission of sidelink data is activated by downlink control information (DCI), and the remaining sidelink transmission resources or transmission parameters are configured at the same time. When the terminal device receives the RRC signaling, it cannot immediately use the resources configured by the RRC signaling for sidelink transmission, but must wait until the above DCI is received before sidelink transmission can be performed. In addition, the network can deactivate the configured authorized transmission resources through DCI. When the terminal receives the deactivated DCI, it can no longer use the configured authorized transmission resources for transmission.

[0038] After the network device allocates the first type of configuration authorized transmission resources or activates the second type of configuration authorized side link transmission resources to the terminal device, when the terminal has side link data to transmit, it can directly use the side link transmission resources for transmission without requesting the network to allocate side link transmission resources, thereby reducing the side link delay.

[0039] The following describes in detail a communication method based on configuration authorization provided in an embodiment of the present application.

[0040] like Figure 2 As shown, the communication method includes:

[0041] S210, the terminal device sends a request message to the network device.

[0042] The terminal device is a transmitter of the sidelink. The request message requests the network device to configure the sidelink transmission resources. Optionally, the terminal device may report in the request message whether it is necessary to send feedback information of the sidelink on the uplink. For example, the terminal device requests to configure the sidelink transmission resources for broadcasting. Since the data transmitted by broadcasting generally does not need to be fed back, the network device may determine that the terminal device does not need to send feedback information of the sidelink on the uplink.

[0043] After receiving the request message, the network device performs the following steps.

[0044] S220, sending configuration authorization information to the terminal device, wherein the configuration authorization information is used to configure sidelink transmission resources and uplink transmission resources. The uplink transmission resource is, for example, a physical uplink control channel (PUCCH), and the uplink transmission resource is used to send sidelink feedback information to the network device, that is, the sidelink feedback information sent by the terminal device (transmitter) to the network device is carried on the PUCCH.

[0045] The network device can directly configure the sidelink transmission resources and uplink transmission resources for the terminal device without considering whether the terminal device needs to send sidelink feedback information on the uplink. That is, the network device can use a configuration authorization information to allocate resources for all terminal devices, reducing the complexity of resource allocation by the network device. In addition, after the network device allocates sidelink transmission resources and uplink transmission resources to all sidelink transmitters, the transmitter can use the sidelink transmission resources to transmit sidelink data that supports sidelink feedback and sidelink data that does not support sidelink feedback; if the transmitter needs to feedback the reception status of burst sidelink data, the transmitter no longer needs to request allocation of uplink transmission resources, thereby improving the flexibility of transmitting uplink data in the V2X communication system.

[0046] The configuration authorization information may be RRC signaling in the first type of configuration authorization, or may be RRC signaling or DCI signaling in the second type of configuration authorization. Optionally, the configuration authorization information may include first indication information for indicating whether to activate sidelink feedback.

[0047] After receiving the configuration authorization information, the terminal device can perform the following steps.

[0048] S230, sending data on the sidelink transmission resource.

[0049] Optionally, the terminal device may send a second indication message to the receiving end on the side link transmission resource, indicating whether to deactivate the side link feedback.

[0050] For example, the terminal device (transmitter) can send sidelink control information (SidelinkControl Information, SCI) to the receiving end, and the SCI includes one bit (i.e., the second indication information); if the unicast data sent by the terminal device through the sidelink transmission resource does not require feedback, the bit of the SCI can be set to "0" to indicate that the feedback of the sidelink transmission is in a deactivated state or a disabled state, that is, the receiving end does not need to send feedback information for the sidelink data to the transmitting end; if the unicast data sent by the terminal device through the sidelink transmission resource requires feedback, the bit of the SCI can be set to "1" to indicate that the feedback of the sidelink transmission is in an activated state or an enabled state, that is, the receiving end needs to send feedback information of the sidelink data to the transmitting end according to the reception status of the sidelink.

[0051] When the data transmitted on the side link needs feedback, the terminal device (transmitter of the side link) can receive HARQ feedback information from the receiving end. The HARQ feedback information can be ACK or negative acknowledgement (NegativeAcknowledgement, NACK). The terminal device sends the received HARQ feedback information to the network device through the uplink transmission resources, so that the network device can determine whether to allocate retransmission resources for the side link.

[0052] When the data transmitted on the sidelink does not require feedback, the terminal device can perform any one of the following steps.

[0053] S240: Determine not to send feedback information of the data on uplink transmission resources.

[0054] S250, sending an Acknowledgement (ACK) on uplink transmission resources.

[0055] The above data does not need to be fed back in the following cases:

[0056] The sidelink transmission does not support HARQ feedback; or, the data transmitted on the sidelink is broadcast data; or, the data transmitted on the sidelink is unicast data or multicast data, but the unicast data or the multicast data does not require HARQ feedback.

[0057] Regardless of whether the terminal device receives feedback information on the sidelink, the terminal device may perform S240 or S250 when no feedback is required for the data.

[0058] The network device may monitor the message of the terminal device on the uplink transmission resource. If the terminal device executes S240, the result of the network device monitoring the message on the uplink transmission resource is discontinuous transmission (DTX), and the network device may determine not to configure the sidelink retransmission resource for the terminal device according to DTX; if the terminal device executes S250, the result of the network device monitoring the message on the uplink transmission resource is ACK, and the network device determines not to configure the sidelink retransmission resource for the terminal device according to the received ACK. This solution can avoid the waste of sidelink retransmission resources.

[0059] It should be understood that this article describes the Internet of Vehicles as an example, but the embodiments of the present application are applicable to any system based on sidelink transmission.

[0060] The above describes in detail an example of a communication method based on configuration authorization provided by an embodiment of the present application.

Professional and technical personnel can use different methods to implement the described functions for each specific application, but such implementation should not be considered to exceed the scope of the embodiments of the present application.

[0061] The embodiment of the present application can divide the functional units of the communication device according to the above method example. For example, each function can be divided into each functional unit, or two or more functions can be integrated into one processing unit. The above integrated unit can be implemented in the form of hardware or in the form of software functional units. It should be noted that the division of units in the embodiment of the present application is schematic and is only a logical function division. There may be other division methods in actual implementation.
