Abstract
Disclosed aspects relate to methods and apparatus for controlling a wireless device having at least one radio frequency (RF) system. The methods and apparatus are configured to select an antenna for transmission of signals from radio components of the at least one RF system from between a first default antenna normally coupled to the radio components of the at least one RF system for transmission of signals and one of a plurality of other antennas in the wireless device. Further, switching is configured to couple the radio components to one of the other plurality of antennas selected as the antenna for transmission cycles when the radio components are transmitting in an antenna switch diversity (ASDIV) period. Additionally, the methods and apparatus are configured to operate a switch to couple the radio components back to at least the first default antenna during receiving cycles during the ASDIV period.
