Method, access point and WTRU for controlling transmission power levels of uplink/downlink communication in a wireless communication system

摘要

Transmission power levels of uplink/downlink communication is controlled in a wireless communication system. A receiving station produces and provides to a transmitting station power control information based upon received signals from the transmitting station. A measured block error rate (BLER_msr) is obtained from the number of erroneous blocks in a sliding window of the last N received data blocks and SIR adjustments are set based upon the BLER_msr and a target BLER (BLER_target). A target SIR of received signals is adjusted according to the SIR adjustments.
