Abstract
A method and apparatus of providing a base station with updated transmission channel information is disclosed. The method includes the base station transmitting beamformed signals to a first terminal. A second terminal receives the transmitted beamformed signals, and measures a signal quality. The second terminal conveys back to the base station the measured signal quality, and a transmission identifier of the beamformed data signal.
