ABSTRACT:
Beam-formed transmission from a transmitting wireless communication station to a receiving wireless communication station is supported by estimating a direction for the beamformed transmission. The receiving station reports to the transmitting station information about wide-beam and narrow-beam pilot signals that the receiving station has received from the transmitting station. The transmitting station estimates the direction of the beamformed transmission based on this information.
