Abstract

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a set of recommended base station transmit beams for full duplex operation based at least in part on measurements of a set of base station transmit beams and measurements of self-interference associated with the set of base station transmit beams. The UE may transmit a report that indicates a recommendation to use one or more of the set of recommended base station transmit beams for full duplex operation. Numerous other aspects are described.

First claim

The invention claimed is:

1 . A method of wireless communication performed by a user equipment (UE), comprising:
transmitting a report indicating a set of recommended base station transmit beams for full duplex operation, the set of recommended base station transmit beams being determined in accordance with measurements of a set of base station transmit beams and measurements of self-interference associated with the set of base station transmit beams; and receiving an indication of one or more base station transmit beams for the full duplex operation.

2 . The method of claim 1 , wherein transmitting the report comprises:
transmitting a channel state information (CSI) report, the CSI report indicating the set of recommended base station transmit beams for the full duplex operation.

3 . The method of claim 1 , wherein transmitting the report comprises:
transmitting a self-interference report, the self-interference report indicating the set of recommended base station transmit beams for the full duplex operation.

4 . The method of claim 1 , wherein transmitting the report comprises:
transmitting the report indicating the set of recommended base station transmit beams for the full duplex operation via radio resource control (RRC) signaling.

5 . The method of claim 1 , wherein transmitting the report comprises:
transmitting uplink control information (UCI), the UCI indicating the set of recommended base station transmit beams for the full duplex operation.

6 . The method of claim 1 , wherein the report includes an explicit indication of the set of recommended base station transmit beams for the full duplex operation.

7 . The method of claim 1 , wherein the report includes an implicit indication of the set of recommended base station transmit beams for the full duplex operation.

8 . The method of claim 7 , wherein the implicit indication includes an indication of one or more base station transmit beams that are not to be used for the full duplex operation.

9 . The method of claim 1 , further comprising:
receiving an allocation of resources for self-interference measurement, the measurements of the self-interference associated with the set of base station transmit beams being determined using the allocation of resources for self-interference measurement.

10 . The method of claim 1 , wherein the measurements for self-interference include one or more of a reference signal received power (RSRP), a signal-to-interference-plus-noise ratio (SINR), or mutual interference information associated with multiple UE receive beams associated with one or more UE transmit beams.

11 . A non-transitory computer-readable medium storing a set of instructions for wireless communication, the set of instructions comprising:
one or more instructions that, when executed by one or more processors of a user equipment (UE), cause the UE to:
transmit a report indicating a set of recommended base station transmit beams for full duplex operation, the set of recommended base station transmit beams being determined in accordance with a set of base station transmit beams and measurements of self-interference associated with the set of base station transmit beams; and
receive an indication of one or more base station transmit beams for the full duplex operation.

12 . The non-transitory computer-readable medium of claim 11 , wherein the one or more instructions, that cause the UE to transmit the report, cause the UE to:
transmit a channel state information (CSI) report or a self-interference report indicating the set of recommended base station transmit beams for the full duplex operation.

13 . The non-transitory computer-readable medium of claim 11 , wherein the one or more instructions, that cause the UE to transmit the report, cause the UE to:
transmit the report indicating the set of recommended base station transmit beams for the full duplex operation via radio resource control (RRC) signaling.

14 . The non-transitory computer-readable medium of claim 11 , wherein the one or more instructions, that cause the UE to transmit the report, cause the UE to:
transmit uplink control information (UCI), the UCI indicating the set of recommended base station transmit beams for the full duplex operation.

15 . The non-transitory computer-readable medium of claim 11 , wherein the report includes an explicit indication of the set of recommended base station transmit beams for the full duplex operation.

16 . The non-transitory computer-readable medium of claim 11 , wherein the report includes an implicit indication of the set of recommended base station transmit beams for the full duplex operation.

17 . The non-transitory computer-readable medium of claim 16 , wherein the implicit indication includes an indication of one or more base station transmit beams that are not to be used for the full duplex operation.

18 . The non-transitory computer-readable medium of claim 11 , wherein the one or more instructions further cause the UE to:
receive an allocation of resources for self-interference measurement, the measurements of the self-interference associated with the set of base station transmit beams being determined using the allocation of resources for self-interference measurement.

19 . The non-transitory computer-readable medium of claim 11 , wherein the measurements for self-interference include one or more of a reference signal received power (RSRP), a signal-to-interference-plus-noise ratio (SINR), or mutual interference information associated with multiple UE receive beams associated with one or more UE transmit beams.

20 . A user equipment (UE) for wireless communication, comprising:
one or more memories; and one or more processors, coupled to the one or more memories, configured to:
transmit a report indicating a set of recommended base station transmit beams for full duplex operation, the set of recommended base station transmit beams being determined in accordance with measurements of a set of base station transmit beams and measurements of self-interference associated with the set of base station transmit beams; and
receive an indication of one or more base station transmit beams for the full duplex operation.

21 . The UE of claim 20 , wherein the one or more processors, to transmit the report, are configured to:
transmit a channel state information (CSI) report, the CSI report indicating the set of recommended base station transmit beams for the full duplex operation.

22 . The UE of claim 20 , wherein the one or more processors, to transmit the report, are configured to:
transmit a self-interference report, the self-interference report indicating the set of recommended base station transmit beams for the full duplex operation.

23 . The UE of claim 20 , wherein the one or more processors, to transmit the report, are configured to:
transmit the report indicating the set of recommended base station transmit beams for the full duplex operation via radio resource control (RRC) signaling.

24 . The UE of claim 20 , wherein the one or more processors, to transmit the report, are configured to:
transmit uplink control information (UCI), the UCI indicating the set of recommended base station transmit beams for the full duplex operation.

25 . The UE of claim 20 , wherein the report includes an explicit indication of the set of recommended base station transmit beams for the full duplex
