Abstract
The invention claims a method for determining uplink transmission power in TDD system comprising: a base station determines current uplink/downlink sub-frame distribution manner and obtains frame corresponding information corresponding to the uplink/downlink sub-frame distribution manner; the base station selects a downlink sub-frame to send transmit power control (TPC) command corresponding to an uplink sub-frame according to the frame corresponding information; before utilizing the uplink sub-frame to transmit data a terminal determines the current uplink/downlink sub-frame distribution manner and obtains frame corresponding information corresponding to the uplink/downlink sub-frame distribution manner then determines the downlink sub-frame which sends the TPC command according to the frame corresponding information; the terminal obtains the TPC command received from the downlink sub-frame and determines power of data transmission performed by utilizing the uplink sub-frame according to the TPC command. The invention further claims a TDD data transmission system and a device. By using the invention the TDD system can send and receive TPC command according to frame corresponding information so as to correctly and effectively control uplink power.
