Methods and apparatus for communicating with multiple antennas

摘要

Wireless communications methods and apparatus for a device using multiple antennas are described. A first wireless communications device receives signals from a second communications device. The first device generates receiver interference estimates corresponding to different antennas and selects one antenna to receive signals from the second device, as a function of the generated receiver interference estimates. The first device receives signals from one or more additional devices to which first device transmission may cause interference. The first device generates transmitter interference estimates corresponding to different antennas and selects one antenna to transmit signals to the second device as a function of the generated transmitter interference estimates. The first device may, and sometimes does, select different receive and transmit antennas for communicating with the second device.
