Abstract

An uplink antenna selection device and method are provided. The device comprises: at least two antennas; at least one antenna feed connected to each antenna, each antenna configured to transmit data on a respective given transmission band paired with a respective associated receive band; and, a processor, in communication with the at least one antenna feed. The processor is configured to: for each of the antennas, determine a respective quality-of-signal (QOS) parameter of at least one respective receive band adjacent to the respective given transmission band, the at least one respective receive band different from the respective associated receive band paired with the respective given transmission band; and control the at least one antenna feed to select one of the antennas for transmitting data on the respective given transmission band based on the respective QOS parameter of the at least one respective receive band for each of the antennas.
