Abstract
A method and apparatus of aiding uplink beamforming transmission is disclosed. One method includes a base station downlink transmitting beamformed signals to at least a first terminal, the beam formed signals directed and conveying data to at least the first terminal. The method further includes a second terminal eavesdropping the transmitted beamformed signals, and measuring a signal quality. The second terminal estimates uplink channel information based on the measured signal quality, for aiding uplink transmission. Based at least in part on the estimated transmission channel, the second terminal transmits beamformed uplink signals to the base station.
