Abstract
A communications terminal may include: a plurality of antennas; and a selection circuit configured to 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 may be based on a selection criterion.
Claims48
A communications terminal, comprising:
- a plurality of antennas;
- and
- a selection circuit configured to 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 for controlling a transmission power of the transmit signal via the plurality of antennas;
- a determining circuit, based on the control information, configured to compare the transmission power of the transmit signal before selecting the at least one antenna to a transmission power of the transmit signal after selecting the at least one antenna, and wherein the selection circuit is further configured to reselect at least one antenna of the plurality of antennas as the transmit antenna if the transmission power of the transmit signal after selecting the at least one antenna is greater than the transmission power of the transmit signal before selecting the at least one transmit antenna.
11-14. (canceled)
The communications terminal of claim 11, wherein the control information comprises control information in a radio link control (RLC) communication layer.
The communications terminal of claim 11, wherein the control information comprises control information in a radio resource control (RRC) communication layer.
The communications terminal of claim 11, the control information for controlling an uplink data transmission parameter of the transmission of the transmit signal on the plurality of antennas.
(canceled)
A method for selecting a transmit antenna of a communications terminal comprising a plurality of antennas and a selection circuit, for a transmission to a radio communications network, the method comprising:
- determining, by the selection circuit, whether a selection criterion is fulfilled;
- and
- selecting at least one antenna of the plurality of antennas as the transmit antenna if the selection criterion is fulfilled,
- wherein determining whether the selection criterion is fulfilled comprises comparing a transmission power of a transmit signal via the plurality of antennas before selecting the transmit antenna to the transmission power of the transmit signal after selecting the transmit antenna.
(canceled)
A communications terminal, comprising:
- a plurality of antennas;
- and
- a selection circuit configured to select at least one antenna of the plurality of antennas as a transmit antenna for a transmission to a radio communications network based on a selection criteria, and
- a controller configured to provide a block instruction to the selection circuit for blocking at least one further reselection of the transmit antenna by the selection circuit.
