Abstract
A method for open loop uplink access power control comprises: estimating the uplink transmission path loss according to received signal power of a station (STA) and the transmit power of a central access point (CAP); determining the transmission bandwidth allocated by the CAP for uplink transmission and deviation adjustment of the CAP; determining a modulation-coding mode and determining requirements of the carrier-to-noise ratio corresponding to the modulation-coding mode; and calculating a target value for adjusting the transmit power of the STA. Also disclosed is a device for open loop uplink access power control.
