Abstract The invention discloses a power control method under multiple time interval mode of power control used in CDMA system. Encoded symbols of whole '1' and whole '0' being related to two corresponding TPC commands are pre-stored receiving end and sending end. Based on whether the present TPC command is same as last one or not, the receiving end determines to send original TPC command or encoded TPC command. Based on received information composed of N entries of TPC command data and conformity of said encoded symbols, the sending end determines how to adjust the power. The invention users encoded symbols instead of TPC commands with whole '1' and whole '0' therefor improves reliability of TPC command, and performance of power control.
