Resource allocation method and device

A resource allocation method, applied to a terminal device in sidelink communication, comprising:

• determining a target resource allocation mode at a current occasion, wherein the target resource allocation mode is one of the following modes:
• random resource allocation mode, dynamic resource allocation mode, and hybrid semi-static/dynamic resource allocation mode;
• determining a resource set corresponding to the target resource allocation mode;
• and
• allocating a resource based on the resource set and the target resource allocation mode.

A terminal device, applied to sidelink communication, comprising:

• a memory, a processor, and a computer program stored in the memory and capable of running on the processor, wherein when the computer program is executed by the processor, following steps are implemented:
• determining a first numerical value of a first counter at a first occasion;
• in a case that the first numerical value is greater than a first preset value, determining an occupancy status of a first transmission resource associated with the first occasion, wherein the first preset value is an integer greater than or equal to 0;
• and
• selecting a target resource for information transmission based on the occupancy status of the first transmission resource.
