Claim Text:
1. A method comprising: transmitting, by a base station to a mobile station, sounding signals via a first set of basis function beams; and receiving, by the base station from the mobile station in response to the transmitting, feedback signals indicating a translated basis-function weighting for one or more basis function beams of a second set of basis function beams, the translated basis-function weighting for one or more basis function beams being based on the first set of basis function beams, wherein the second set of basis function beams is different than the first set of basis function beams; wherein the base station includes Q antennas, wherein the transmitting sounding signals via a first set of basis function beams comprises transmitting a pilot sequence from each of the Q antennas for each beam of the first set of basis function beams, an individual gain and phase value being applied to each of the Q antennas for each beam of the first set of basis function beams.
