Claim 5:
6. A communication method for an initiator apparatus that includes a plurality of transmission antennas, the communication method comprising:
transmitting first training packets for transmission sector sweeping (TXSS) by the initiator apparatus that includes the plurality of transmission antennas;
transmitting second training packets for reception sector sweeping (RXSS) by a responder apparatus that comprises a plurality of reception antennas;
transmitting third training packets for beam combination training between the initiator apparatus and the responder apparatus;
selecting a subset of candidate transmission sectors for each of the plurality of transmission antennas;
obtaining a subset of candidate reception sectors for each of the plurality of reception antennas; and
determining N transmission/reception sector combinations from the subset of candidate transmission sectors and the subset of candidate reception sectors, each of the N transmission/reception sector combinations comprising a transmission sector and a reception sector, wherein N is an integer that is larger than one, and wherein each of the plurality of transmission antennas of the initiator apparatus corresponds to a single transmission sector and each of the plurality of reception antennas of the responder apparatus corresponds to a single reception sector.
