Technical field

The present disclosure relates to the field of communication, and in particular, to a V2X communication method and device, storage medium, and electronic device.

Background technique

In Long Term Evolution (LTE) Vehicle to Everything (V2X) technology, the user equipment (UE) in the coverage determines the sidelink transmission resource pool on a carrier according to the configuration information With the sidelink receiving resource pool, the out-of-coverage UE determines the sidelink sending resource pool and the sidelink receiving resource pool on a certain carrier according to the pre-configuration, and the sidelink sending resource pool also belongs to the sidelink receiving resource pool. For the UE in mode 3 mode, the resource for sending the V2X message is determined in the sidelink transmission resource pool according to the indication of the downlink control information (Downlink Control Information, DCI). And, receive V2X messages in the sidelink receiving resource pool; for UEs in mode 4 mode, they can independently select V2X message sending resources by monitoring the resources of the sidelink sending resource pool. Specifically, they first exclude resources occupied or reserved by other UEs , Select the resource subset with the lowest probability of collision with other UEs, and then randomly select V2X transmission resources from this subset. And, receive V2X messages in the pre-configured sidelink receiving resource pool.

Sidelink bandwidth part (Sidelink Bandwidth part, SL BWP) is a new concept of new radio technology (New Radio, NR) V2X, used to limit the frequency domain range of resources that can be used for NR V2X communication on a carrier. According to the conclusion of the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3gpp) RAN1#95 meeting, for radio resource control_connected terminal (Radio Resource Control_connected User Equipment, RRC_connected UE), one carrier can only activate one SL BWP, For radio resource control_idle terminal (Radio Resource_Control_idle User Equipment, RRC_idle UE) or out-of-coverage UE, one carrier can only be configured or pre-configured with one SL BWP. Also, the SL and BWP used for transmission and reception are the same.

At the edge of network coverage, in-coverage UEs and out-of-coverage UEs are close to each other, and there is a need for V2X communication. At least in the licensed frequency band carrier, the UE within the coverage determines the SL BWP for NR V2X communication according to the configuration, and the UE outside the coverage determines the SL BWP for NR V2X communication according to the pre-configuration. According to the conclusion of the 3gpp RAN1#95 meeting, the SL and BWP used for sending and receiving are the same. Then, when the SL configured within the coverage and the BWP configured outside the coverage are inconsistent, the NR V2X communication between the coverage UE and the coverage UE cannot be achieved.
