DYNAMIC ANTENNA SELECTION IN A WIRELESS DEVICE

摘要

Techniques for supporting a plurality of radios (240) on a wireless device (110) with a limited number of antennas (210) are described. In one design, at least one radio may be selected from among the plurality of radios on the wireless device. At least one antenna may be selected for the at least one radio from among a plurality of antennas, e.g., based on a configurable mapping of the plurality of radios to the plurality of antennas. One or more antennas may be shared between radios to reduce the number of antennas. The at least one radio may be connected to the at least one antenna, e.g., via a switchplexer (220). Antenna selection may be performed dynamically (e.g., when the at least one radio becomes active, or when a change in performance of the at least one radio is required) such that good performance can be obtained.
