Abstract: An apparatus configured to enable different modes of concurrent radio transmission and radio reception, in the same time-frequency channel, using multiple antennas, the apparatus comprising means for



a) selecting concurrent transmission and reception on different ones of the multiple antennas,
b) selecting concurrent transmission and reception at overlapping frequencies or at non-overlapping frequencies,
c) selecting one of non-diversity reception, diversity reception, or multiple-input multiple-output (MIMO) reception.

Abstract: An apparatus comprising includes first and second radio frequency circuitry configured for operation at least in one or more first and second radio frequency bands, respectively; and first and second antenna arrangements configured for operation in the one or more first and second radio frequency bands, respectively. The apparatus also includes first and second radio frequency coupling for transferring of a signal between the first and second antenna arrangements, respectively, and the first and second radio frequency circuitry, respectively. The apparatus further includes a controller for assessing whether a signal can be transferred between the second antenna arrangement and the first radio frequency circuitry and, in dependence upon the assessment, for transferring the signal therebetween, via a frequency converter configured to enable, for the signal, frequency conversion between the one or more second radio frequency bands and the one or more first radio frequency bands.
