Abstract

The embodiment of the present application discloses a communication method and device, which relate to the field of communication technology and solve the problems caused by the transmission of V2X services in different frequency bands through the same QoS flow. The method includes: the sending end determines the layer 2 address pair of the first V2X service according to the frequency band of the first V2X service, and the layer 2 address pair of the first V2X service includes the source layer 2 address of the first V2X service and the first V2X service The destination layer 2 address of the first V2X service, the layer 2 address pair of the first V2X service corresponds to the frequency band of the first V2X service; the sending end sends the first Data of V2X services.

Description

technical field [0001] The embodiments of the present application relate to the field of communication, and in particular, to a communication method and apparatus. Background technique [0002] In a vehicle to everything (V2X) communication system, V2X services can be transmitted between terminals through the PC5 port. For example, before the sender transmits the V2X service to the receiver, the sender can establish a PC5 signaling plane (PC5 signal, PC5-S) connection with the receiver, and negotiate a pair of layer 2 (layer2, L2) addresses through the PC5 unicast connection (or referred to as a layer 2 address pair), the pair of addresses includes a source layer 2 address and a destination layer 2 address. Subsequently, when the sender sends the V2X service to the receiver, the sender can filter the V2X service to the corresponding QoS flow according to the quality of service (QoS) requirements of the V2X service, and filter the QoS flow and the QoS flow. The obtained pai...
