A method () and apparatus () for selecting one of a plurality of antennas (), on a UE () implementing transmit diversity in a multi-carrier wireless communication system, for the joint transmission of two or more uplink signals, each modulated onto a different carrier frequency, such as when the carriers share a power amplifier (). The method () and apparatus () select an antenna () based on channel conditions associated with the carriers, even when prior art transmit diversity methods provide conflicting antenna selection indications.
