Detailed ways

The technical solutions in the embodiments of the present application will be described below 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 this application, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of this application.

Fig. 1 shows a schematic diagram of a communication system 100 applicable to an embodiment of the present application.

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, or in-vehicle electronic systems, mobile phones, wearable electronic devices, or other communication devices that implement the V2X protocol.

The network equipment 110 may be an evolved base station (evolutional Node B, eNB) in the LTE system, or a base station (gNB) in a 5G communication system. The above network equipment is only an example. The network equipment 110 may also be a relay station, Entry points, in-vehicle devices, wearable devices, and other types of devices.

Before transmitting data through the side link, the terminal device 121 and the terminal device 122 may determine the side link transmission resource through the instruction of the network device 110. The terminal device 121 and the terminal device 122 may also determine the side link transmission resource without using the instruction of the network device 110.

The above two examples are the two transmission modes of side-link communication, the centralized scheduling transmission mode (also referred to as mode 1) and the distributed transmission mode (also referred to as mode 2). Below, a brief introduction to the two transmission modes:

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 equipment are uniformly allocated by the network equipment, there will be no situation where adjacent terminal equipment is allocated the same resources, and the centralized scheduling transmission mode has better transmission reliability. However, due to the need to exchange signaling between the terminal equipment and the network equipment, compared with the distributed transmission mode, the transmission delay of sending data in the centralized scheduling transmission mode is longer.

Distributed transmission mode: In scenarios with network coverage, network equipment can configure resource pools for terminal equipment through System Information Block (SIB) or Radio Resource Control (RRC) signaling, and the terminal equipment sends In the case of V2X data, data can be sent by obtaining some resources from the resource pool autonomously through random selection, based on the listening reservation mechanism, or based on the partial listening reservation mechanism. In a scenario where there is no network coverage, the terminal device autonomously obtains some resources from the resource pool configured by the pre-configuration information to send data. The pre-configuration information may be the information that the terminal device is configured inside the terminal device when it leaves the factory, or it may be the information that is pre-configured by the network device and stored inside the terminal device. Since terminal devices can independently select resources, it may happen that different terminal devices select the same resource to send data. Therefore, compared to the centralized scheduling transmission mode, the reliability of using the distributed transmission mode to send data is lower.

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

In some cases, the terminal device on the side link needs to send uplink data. For example, after the sending end sends the side line data to the receiving end, the receiving end receives feedback information indicating the reception of the side line data; if the feedback information indicates that the side line data reception failed, the sending end can send to the network device The feedback information facilitates the network equipment to allocate retransmission resources for the side line data.

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

The first type of configuration grant (type-1 configured grant): The network device configures the side link transmission resources for the terminal device through RRC signaling. The content of the RRC signaling configuration includes the transmission resources and transmission required by the terminal for side transmission. Parameters, such as time domain resources, frequency domain resources, demodulation reference signal information, etc. After receiving the RRC signaling, the terminal device can immediately use the sidelink transmission resources configured by the RRC signaling to send sideline data.

The second type of configuration grant (type-2 configured grant): First, the RRC signaling configures part of the side link transmission resources and transmission parameters, and then the downlink control information (Downlink Control Information, DCI) activates the transmission of the side line data , And configure the remaining side link transmission resources or transmission parameters at the same time. When the terminal device receives the RRC signaling, it cannot immediately use the resources configured by the RRC signaling to perform side-line transmission, and must wait for the above-mentioned DCI to perform side-line transmission. In addition, the network can deactivate and configure authorized transmission resources through DCI. After receiving the deactivated DCI, the terminal can no longer use the configured authorized transmission resources for transmission.

After the network device allocates the transmission resources of the first type of configuration authorization or the activated side link transmission resources of the second type of configuration authorization to the terminal device, when the terminal has side-line data to transmit, it can directly use the side-line transmission resource Transmission is performed without the need to request the network to allocate side-line transmission resources, thereby reducing the side-line delay.

Hereinafter, the communication method based on configuration authorization provided in the embodiment of the present application will be described in detail.

As shown in Figure 2, the communication method includes:

S210: The terminal device sends a request message to the network device.

The above-mentioned terminal equipment is the transmitting end of the side link. The above request message requests the network device to configure the side link transmission resource. Optionally, the terminal device may report in the request message whether it is necessary to send side uplink feedback information on the uplink. For example, a terminal device requests to configure side-link transmission resources for broadcasting. Since broadcast transmission data generally does not require feedback, the network device can determine that the terminal device does not need to send side-link feedback information on the uplink. .

After the network device receives the request message, perform the following steps.

S220: Send configuration authorization information to the terminal device, where the configuration authorization information is used to configure side link 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 side uplink feedback information to a network device, that is, the terminal device (send End) side link feedback information sent to the network device.

The network device can directly configure the side link transmission resource and the uplink transmission resource for the terminal device without considering whether the terminal device needs to send side link feedback information on the uplink. That is, the network device can use a configuration authorization information to allocate resources for all terminal devices, which reduces the complexity of resource allocation by the network device. In addition, after the network device allocates side-link transmission resources and uplink transmission resources to all side-link transmission ends, the transmitting end can use the side-link transmission resources to transmit side-line data that supports side-line feedback and It does not support the side-line data that is fed back by the side line; if the sender needs to feedback the reception of the burst side-line data, the sender does not need to request the allocation of uplink transmission resources, thereby improving the flexibility of uplink data transmission in the V2X communication system Sex.

The foregoing configuration authorization information may be RRC signaling in the first type of configuration authorization, and may also be RRC signaling or DCI signaling in the second type of configuration authorization. Optionally, the configuration authorization information may include first indication information, which is used to indicate whether to activate side link feedback.

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

S230: Send data on the side link transmission resource.

Optionally, the terminal device may send second indication information to the receiving end on the above-mentioned side-link transmission resource, indicating whether to deactivate the side-link feedback.

For example, the terminal device (transmitting end) may send Sidelink Control Information (SCI) to the receiving end, and the SCI contains one bit (ie, the second indication information); if the terminal device passes the sidelink control information, The unicast data sent by the 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 the deactivated state or disabled state, that is, the receiving end does not need to send feedback to The sender sends feedback information for the side-line data; if the unicast data sent by the terminal device through the side-line link transmission resource needs to be fed back, the bit of the SCI can be set to "1" to indicate the side-line link transmission The feedback is in the active state or enabled state, that is, the receiving end needs to send feedback information of the side line data to the transmitting end according to the receiving state of the side line link, such as Hybrid Automatic Repeat reQuest (HARQ) ACK or HARQ NACK.

When the data transmitted on the side link needs to be fed back, the terminal device (the sending end of the side link) can receive HARQ feedback information from the receiving end. The HARQ feedback information can be an ACK or a negative acknowledgement (Negative Acknowledgement, NACK). The terminal device sends the received HARQ feedback information to the network device through uplink transmission resources, so that the network device can determine whether it is necessary to allocate the retransmission resources of the side uplink.

When the data transmitted on the side link does not require feedback, the terminal device can perform any of the following steps.

S240: Determine not to send feedback information of the data on the uplink transmission resource.

S250: Send an acknowledgement (Acknowledgement, ACK) on the uplink transmission resource.

The above data does not require feedback and can include the following situations:

The side link transmission does not support HARQ feedback; or, the data transmitted on the side link is broadcast data; or, the data transmitted on the side link is unicast data or multicast data, but the unicast data or the Multicast data does not require HARQ feedback.

Regardless of whether the terminal device receives feedback information on the side link, the terminal device can perform S240 or S250 when the data does not need to be fed back.

The network device can listen to the message of the terminal device on the uplink transmission resource. Among them, if the terminal device executes S240, the result of the network device listening to the message on the uplink transmission resource is Discontinuous Transmission (DTX), and the network device can determine not to configure side uplink reconfiguration for the terminal device according to DTX. If the terminal device performs S250, the result of the network device monitoring the message on the uplink transmission resource is an ACK, and the network device determines not to configure the side link retransmission resource for the terminal device according to the received ACK. This solution can avoid the waste of retransmission resources on the side link.

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