Downlink power control for multiple downlink time slots in TDD communication systems

摘要

A method for downlink power control for use in a spread spectrum time division communication system having time slots for communication, implemented in a user equipment, includes receiving data in a command per coded composite transport channel (CCTrCH) transmitted over a plurality of time slots. An interference power for each time slot of the plurality of time slots is measured and a single power command for the entire CCTrCH is transmitted in response to a signal to interference ratio of the received CCTrCH and the measured interference power measurement for each time slot. A subsequent data is received in the CCTrCH communication having a transmission power level for each downlink communication time slot set individually in response to the interference power measurement for that time slot and the single power command for the entire CCTrCH.

1. An integrated circuit (IC), comprising:
circuitry configured to receive data in a command per coded composite transport channel (CCTrCH) transmitted over a plurality of time slots; circuitry configured to measure an interference power for each time slot of the plurality of time slots: circuitry configured to output for transmission a single power command for the entire CCTrCH in response to a signal to interference ratio of the received CCTrCH and the measured interference power measurement for each time slot; and circuitry configured to receive a subsequent data in the CCTrCH communication having a transmission power level for each downlink communication time slot set individually in response to the interference power measurement for that time slot and the single power command for the entire CCTrCH.
