Abstract
A method for determining uplink transmission power in time division duplex system is disclosed: a base station determines the current distribution manner of uplink and downlink sub-frames acquires the frame correspondence information that corresponds to the distribution manner of said uplink and downlink sub-frames selects based on said frame correspondence information downlink sub-frames to transmit to a terminal the power control (TPC) commands that correspond to the uplink sub-frames. Before using the uplink sub-frames to transmit data the terminal determines the current distribution manner of uplink and downlink sub-frames acquires the frame correspondence information that corresponds to the distribution manner of said uplink and downlink sub-frames determines based on the frame correspondence information the downlink sub-frames that are used for transmitting the TPC commands; acquires the TPC commands received by the downlink sub-frames and determines the data transmission power of the uplink sub-frames based on said TPC commands. The present invention also discloses a time division duplex data transmission system and an apparatus therefor. With the present invention a time division duplex system can transmit and receive TPC commands based on the frame correspondence information thereby enabling correct and effective uplink power control performance.
