Wireless communication method and device

A terminal device, wherein the terminal device is a first terminal device, comprising:

• a processor;
• a memory;
• and
• a transceiver,
• wherein the memory is used to store a computer program, and the processor is used to call and run the computer program stored in the memory to:
• report capability information of the first terminal device and capability information of a third terminal device to a network device via the transceiver;
• acquire a first transmission resource set configured by the network device for performing sidelink communication via the transceiver;
• and
• perform the sidelink communication with the third terminal device using a resource in the first transmission resource set.

A network device, comprising:

• a processor;
• a memory;
• and
• a transceiver,
• wherein the memory is used to store a computer program, and the processor is used to call and run the computer program stored in the memory to:
• acquire capability information of a first terminal device and capability information of a third terminal device via the transceiver;
• and
• send first information to the first terminal device based on the capability information of the first terminal device and the capability information of the third terminal device via the transceiver, the first information indicating a first transmission resource set for the first terminal device to perform sidelink communication.
