V2X communication method and V2X communications apparatus

An apparatus applied for a vehicle to everything (V2X) communication, comprising:

• at least one processor;
• one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least one processor to perform operations comprising:
• obtaining a first correspondence between service information and a first transmission parameter, wherein the service information comprises any one or more of the following:
• a service identifier, a ProSe per-packet priority (PPPP) of a service, a ProSe per-packet reliability (PPPR) of a service, or a quality of service flow identifier (QFI), and wherein the first transmission parameter comprises information about an allowed first-type resource and information about an allowed second-type resource, and wherein the allowed first-type resource is a resource preconfigured by a network device, and the allowed second-type resource is a semi- persistent scheduling resource or a dynamic scheduling resource;
• obtaining a transmission resource and a second transmission parameter corresponding to the transmission resource, wherein the second transmission parameter has an association relationship with the first transmission parameter, or the second transmission parameter belongs to the first transmission parameter;
• and
• allocating, based on the first correspondence and the second transmission parameter corresponding to the transmission resource, the transmission resource to a to-be-transmitted data packet corresponding to the service information.

A non-transitory computer-readable media storing computer instructions, that when executed by one or more processors, cause the one or more processors to perform steps comprising:

• obtaining a first correspondence between service information and a first transmission parameter, wherein the service information comprises any one or more of the following:
• a service identifier, a ProSe per-packet priority (PPPP) of a service, a ProSe per-packet reliability (PPPR) of a service, or a quality of service flow identifier (QFI), and wherein the first transmission parameter comprises information about an allowed first-type resource and information about an allowed second-type resource, and wherein the allowed first-type resource is a resource preconfigured by a network device, and the allowed second-type resource is a semi- persistent scheduling resource or a dynamic scheduling resource;
• obtaining a transmission resource and a second transmission parameter corresponding to the transmission resource, wherein the second transmission parameter has an association relationship with the first transmission parameter, or the second transmission parameter belongs to the first transmission parameter;
• and
• allocating, based on the first correspondence and the second transmission parameter corresponding to the transmission resource, the transmission resource to a to-be-transmitted data packet corresponding to the service information.
