Abstract
A system for controlling transmit power at a station in a multiple in, multiple out (MIMO) system is disclosed. The system includes a signal to interference-plus-noise ratio (SINR) generator configured to predict a post-processing SINR, based on at least one previous and current SINR estimate, for each spatial stream. A power control bit (PCB) generator is configured to generate at least one PCB based on the predicted SINR, which is transmitted to the station at which transmit power is controlled, by a transceiver module, where the stations is a base station or a mobile station. A power control step (PCS) generator is configured to determine a PCS size based on the PCB.
