More Information
Summary:A first wireless communication device is in communication with a second wireless communication device over an uplink communication link from the first wireless communication device to the second wireless communication device. Adaptive uplink antenna switching is performed at the first wireless communication device by switching between at least two antennas at the first wireless communication device in accordance with at least one antenna switching parameter to support the uplink communication link, determining whether each antenna switch is successful or unsuccessful and accumulating a history of successful and unsuccessful antenna switches. The at least one antenna switching parameter is modified based on the accumulated history of successful and unsuccessful antenna switches.
