Abstract
A system and method of training antennas for two devices having heterogeneous antenna configurations in a wireless network is disclosed. The method includes communicating one or more estimation training sequences between two devices via a phased array antenna and a switched array antenna, wherein a beamforming vector of the phased array antenna is switched between phase vectors within a set of weight vectors while the switched array antenna is switched within a plurality of antenna sectors. The method further includes tuning at least one of the phase array and switched array antennas with an antenna parameter selected based at least in part on the one or more estimation training sequences. The method further includes communicating data messages via at least one of the phase array and switched array antennas so tuned.
