Abstract
A base station is capable of communicating with a plurality of subscriber stations using a beamforming scheme that varies beams over different time instances. The base station includes a plurality of antenna arrays configured to transmit N spatial beams and carry a reference symbols corresponding to specific spatial beams. The base station also includes NRF number of radio frequency (RF) processing chains coupled to respective ones of the plurality of antenna arrays, wherein N>>NRF. The subscriber station includes MRF processing receive paths configured to receive M number of beams from the base station.
