Communication method and apparatus in wireless communication system

A communication method in a wireless communication system, comprising:

• determining, by a first terminal device, first channel quality reporting information, wherein:
• a format of the first channel quality reporting information is one of at least two preset formats;
• the first channel quality reporting information includes a channel quality parameter of at least one target channel determined by the first terminal device;
• and
• the target channel is a radio channel between the first terminal device and a second terminal device;
• sending, by the first terminal device, the first channel quality reporting information to the second terminal device;
• and
• receiving, by the first terminal device, a channel quality assessment request from the second terminal device, wherein the channel quality assessment request includes reporting mode indication information that indicates the format of the first channel quality reporting information.

A wireless communication system, comprising:

• a first terminal, wherein the first terminal is configured to:
• receive first channel quality reporting information from a second terminal device, wherein:
• a format of the first channel quality reporting information is one of at least two preset formats;
• the first channel quality reporting information includes a channel quality parameter of at least one target channel determined;
• and
• the target channel is a radio channel between the second terminal device and the first terminal device;
• parse the first channel quality reporting information to obtain the channel quality parameter of the at least one target channel;
• update a first frequency hopping map based on the channel quality parameter of the at least one target channel, wherein the first frequency hopping map is useable by the first terminal device to determine at least one available channel between the first terminal device and the second terminal device;
• and
• send a channel quality assessment request to the second terminal device, wherein:
• the channel quality assessment request includes reporting mode indication information that indicates the format of the first channel quality reporting information.
