Communication Method and Communications Apparatus

A communications apparatus, comprising:

• a memory configured to store instructions;
• and
• at least one processor in communication with the memory and configured to execute the instructions to:
• receive communication quality reference information of a Uu interface from a network device;
• and
• determine, based on the communication quality reference information of the Uu interface and communication quality information of a PC5 interface, a communication mode to send target data to a second terminal device,
• wherein the communication mode is any one of a Uu interface communication mode or a PC5 interface communication mode, and
• wherein the PC5 interface is for direct communication between a first terminal device and the second terminal device.

A communications apparatus, comprising:

• a memory configured to store instructions;
• and
• at least one processor in communication with the memory and configured to execute the instructions to:
• obtain communication quality reference information of a Uu interface, wherein the Uu interface comprises a first Uu interface of a first terminal device and/or a second Uu interface of a second terminal device, wherein the first terminal device is a transmit end of target data, and wherein the second terminal device is a receive end of the target data;
• and
• send the communication quality reference information of the Uu interface to the first terminal device.
