A configuration method for transmitting TPC command, a TPC command transmission method, and an apparatus. In the present invention, a radio network controller sends indication information to a terminal and a serving base station of the terminal to indicate a sending timeslot of an uplink TPC command of the terminal, so that sending timeslots of different TPC commands can be indicated for different terminals, and uplink TPC commands of multiple terminals are staggered in a timeslot. In this way, even if F-DPCHs of multiple terminals are configured with a same timeslot format, it can be avoided that locations of the uplink TPC commands are the same, and further a TPC peak-to-average ratio is lower than that in the prior art.
