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 fora) 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.

First claim

I/We claim:

1 - 14 . (canceled)

15 . An apparatus comprising:
at least one processor; and at least one memory storing instructions that, when executed by the at least one processor, cause the apparatus at least to enable different modes of concurrent radio transmission and radio reception, in the same time frequency channel, using multiple antennas, the apparatus being further configured to: a) select concurrent transmission and reception on different ones of the multiple antennas, b) select at least one of the following: concurrent transmission and reception at overlapping frequencies, or concurrent transmission and reception at non-overlapping frequencies, c) select at least one of the following: non-diversity reception, diversity reception, or multiple-input multiple-output reception.

16 . An apparatus as claimed in claim 15 wherein concurrent transmission and reception in the same time-frequency channel comprises simultaneous transmission and reception in the same operational frequency band.

17 . An apparatus as claimed in claim 15 , wherein the apparatus is further configured to selectively enable at least one of the following:
self-interference cancellation at reception; or differential self-interference cancellation at reception using signals received at two or more antennas; or frequency specific filtration at reception when concurrent transmission and reception at non-overlapping frequencies has been selected.

18 . An apparatus as claimed in claim 15 , wherein the apparatus is further configured to perform at least one of the following:
selection of concurrent transmission and reception at overlapping frequencies is controlled by messages received from a network, or selection of concurrent transmission and reception at non-overlapping frequencies is controlled by messages received from a network, or selection of multiple-input multiple-output reception is controlled by messages received from a network.

19 . An apparatus as claimed in claim 18 , wherein the messaging from the network is dependent upon a data transfer demand provided to the network by the apparatus, wherein multiple input multiple output reception provides higher bandwidth.

20 . An apparatus as claimed in claim 15 , wherein the apparatus is further configured to perform at least one of the following:
selecting non-diversity reception is controlled by the apparatus, or selecting diversity reception is controlled by the apparatus.

21 . An apparatus as claimed in claim 20 , wherein the apparatus is further configured to perform at least one of the following:
selection is based on a number of available antennas, or selection is based on a quality of a reception communication channel between a network and the apparatus.

22 . An apparatus as claimed in claim 15 , configured to selectively enable self-interference cancellation at reception; wherein selectively enabling self-interference cancellation is controlled by the apparatus.

23 . An apparatus as claimed in claim 22 , wherein determining whether or not to selectively enable self-interference cancellation is based on an extent of interference by transmission from the apparatus on reception at the apparatus.

24 . An apparatus as claimed in claim 22 , configured to selectively enable differential self-interference cancellation at reception; wherein selecting between self-interference cancellation and differential self-interference cancellation is controlled by the apparatus.

25 . An apparatus as claimed in claim 22 , wherein determining whether or not to selectively enable self-interference cancellation or differential self-interference cancellation is based on a number of available antennas.

26 . An apparatus as claimed in claim 15 , configured to selectively enable frequency specific filtration at reception, wherein selecting frequency specific filtration at reception is controlled by the apparatus.

27 . An apparatus as claimed in claim 15 , configured or configurable as user equipment.

28 . A method comprising:
enabling different modes of concurrent radio transmission and radio reception, in the same time-frequency channel, using multiple antennas, the method further comprising: 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 reception.
