Patent ID: 8917208

Claim:
A method of training antennas for two devices having heterogeneous antenna configurations in a wireless network, the method comprising: generating estimation training sequences by a first device; communicating the estimation training sequences between the first device and a second device, the first device including a first antenna and the second device including a second antenna, wherein for a beamforming vector for a first antenna, the first antenna switches between phase vectors within a set of weight vectors for a first estimation training sequence, and for each subsequent estimation training sequence that is communicated, the first antenna switches between phase vectors within said set of weight vectors as in the first estimation training sequence while the second antenna is switched to a different antenna sector within a plurality of antenna sectors; tuning at least one of the first antenna and the second antenna with an antenna parameter selected based at least in part on the estimation training sequences, wherein the estimation training sequences are based on antenna configuration of the first antenna; and exchanging messages between the first device and the second device prior to transmitting the first estimation training sequence indicating antenna type for the first antenna and the second antenna, wherein the antenna type comprises one of a switched array antenna and a phased array antenna.
