Antenna selection for coexistence of multiple radio interfaces

摘要

A wireless communication device comprises a wide area transceiver, an auxiliary receiver, a plurality of antennas for use by said auxiliary receiver and said wide area transceiver, and an antenna selection circuit. The antenna selection circuit selects an antenna configuration for the auxiliary receiver and the wide area transceiver. The antenna selection circuit is configured to measure a link quality for one or more of antennas used by the auxiliary receiver, and select an antenna configuration for the wide area transceiver based on the link quality measurements for the auxiliary receiver.

1. A method of antenna selection in a wireless communication device having a wide area transceiver, an auxiliary receiver, and a plurality of selectable antennas, said method comprising:
measuring link quality for each of two or more antennas used by the auxiliary receiver by:
obtaining first link quality measurements from the wide area transceiver and the auxiliary receiver for a first antenna configuration having a first antenna as a primary antenna;swapping the first antenna configuration with a second antenna configuration having a second antenna as the primary antenna;obtaining second link quality measurements from the wide area transceiver and the auxiliary receiver for the second antenna configuration; if each of the first and second link quality measurements exceed a predetermined threshold, selecting an antenna configuration that provides the highest link quality for the auxiliary receiver; and if either one or both of the first and second link quality measurements do not exceed the predetermined threshold, selecting an antenna configuration that provides the highest link quality for the wide area transceiver.
