CPC Class H04W

Provided are a frequency information reporting method performed by a terminal in a wireless communication system, and the terminal using the method. The method generates first frequency information indicating a frequency enabling a terminal sidelink operation to be performed, and second frequency information indicating a frequency enabling a relay sidelink operation to be performed, and transmits the first frequency information and the second frequency information to a network.

The present disclosure discloses a channel sounding information feedback method, user equipment, and a base station. The method includes: determining, by UE, a first period used to periodically report channel sounding information; and periodically sending, by the UE based on received preset downlink control information DCI that is sent by a base station, the channel sounding information by using the first period as a sending period. System overheads can be reduced, a configuration response can be improved, and spectrum utilization of a system can be improved while periodic feedback of indication is reduced.
