Claim:
1. A communications terminal, comprising: a plurality of antennas; and a selection circuit configured to dynamically select at least one antenna of the plurality of antennas as a transmit antenna for a transmission to a radio communications network, wherein a selection of the transmit antenna is based on a selection criterion, wherein the communication terminal receives control information, for controlling a transmission of a transmit signal via the plurality of antennas, from the radio communications network, wherein the control information comprises power control information that indicates a requested transmission power for the transmission of the transmit signal via the plurality of antennas; a determining circuit configured to, based on the control information, configured to compare the requested transmission power of the transmit signal before selecting the at least one antenna to the requested transmission power of the transmit signal after selecting the at least one antenna, and determining whether there has been a condition change in one or more of a measured receive signal strength indicator (RSSI), a measured receive signal code power (RSCP) and a measured reference signal receive power (RSRP), wherein the selection circuit is further configured to reselect at least one antenna of the plurality of antennas as the transmit antenna if a result of the comparison of the requested transmission power before selecting the at least one antenna to the requested transmission power of the transmit signal after selecting the at least one antenna indicates that the requested transmission power of the transmit signal after selecting the at least one antenna is greater than the requested transmission power of the transmit signal before selecting the at least one transmit antenna and subject to cross-checking the result of the comparison of the requested transmission power before selecting the at least one antenna to the transmission power of the transmit signal after selecting the at least one antenna based on the determined condition change.
