Methods and apparatuses for channel measurement are provided. A terminal receives received signal strength indicator (RSSI) measurement timing configuration (RMTC) parameters sent by a base station. The RMTC parameters may include indication information of at least one sub-carrier gap and a terminal measurement duration corresponding to the indication information. The different pieces of indication information may correspond to different terminal measurement durations. The terminal may further determine, according to the indication information of the at least one sub-carrier gap and the terminal measurement duration corresponding to the indication information, a target terminal measurement duration corresponding to at least one target sub-carrier gap to be measured. The terminal may also perform channel measurement according to the target terminal measurement duration.
