Abstract: Method and apparatus to allow a UE to request termination of an FD operation based on a timing different of uplink reception timing and downlink reception timing. The apparatus communicates with at least one TRP in a full duplex operation. The apparatus measures a timing difference of an uplink reception timing and a downlink reception timing of the full duplex operation. The apparatus transmits, to the at least one TRP, a request to terminate the full duplex operation based at least on the timing difference.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a base station, a first reported beam switch timing value and a second reported beam switch timing value. The UE may receive downlink control information (DCI) associated with an aperiodic channel state information reference signal (CSI-RS). The UE may receive the aperiodic CSI-RS based at least in part on applying a beam indicated in the DCI in accordance with one of the first reported beam switch timing value or the second reported beam switch timing value being based at least in part on one or more of whether tracking reference signal (TRS) information is configured for the UE or whether a repetition is associated with the aperiodic CSI-RS. Numerous other aspects are provided.

Abstract: In multi-beam communication, the UE may assist in the scheduling of beams utilized during the multi-beam communication by improving the manner in which the quality of the beam is reported to the network. The apparatus may measure a signal received from a base station on at least one beam. The apparatus may detect a triggering event for providing CSI for the at least one beam. The apparatus may transmit an uplink transmission comprising a CSI report in response to detecting the triggering event. The apparatus may receive an uplink request from a UE for providing CSI for at least one beam. The apparatus may transmit an indication scheduling a CSI report in response to the uplink request. The apparatus may receive an uplink transmission from the UE comprising the CSI report for the at least one beam.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for ACK/NACK-triggered communications with a UE based on multiple ACK/NACK bits in HARQ feedback from a UE. The UE may receive a configuration for a resource, monitor for one or more PDSCH transmissions, and transmit an uplink transmission including HARQ feedback carrying multiple NACK or ACK bits for the one or more PDSCH transmissions. The UE may transmit or receive communication in the resource based on a trigger in the HARQ feedback for transmission or reception of the communication in the resource.

Abstract: Aspects relate to detecting beam failure. A beam failure in a full-duplex communication scenario may be detected based on a reference signal measurement. For example, a user equipment (UE) may measure a downlink reference signal transmitted by a base station and/or an uplink reference signal transmitted by the UE and derive a quality parameter based on one or both of these measurements. If the quality parameter indicates a beam failure, the UE may generate an indication that one or more of the beams monitored by the UE have failed.

Abstract: Aspects relate to reporting beam failure. Upon detecting a beam failure, a user equipment (UE) may transmit a beam failure recovery request to a base station. If the uplink is working, the UE may transmit the beam failure recovery request via uplink signaling (e.g., via a physical uplink control channel or a physical uplink shared channel). If the uplink is not working or if the beam failure is due to downlink quality degradation, the UE may transmit the beam failure recovery request via a random access channel (RACH) message.

Abstract: Certain aspects of the present disclosure provide techniques for transmitting simultaneous multi-beams on the same wireless resource. One example method includes determining a set of transmission (TX) beams for simultaneous transmissions to or from a user equipment (UE), signaling to the UE an indication of the TX beams, and transmitting simultaneously via the TX beams.

Abstract: In order to overcome problems that a UE may face in determining a default beam for communication with the base station during a COT, a method, apparatus, and computer-readable medium are provided for a base station to indicate to the UE which CORESET(s), QCL assumptions, UL resources, and/or spatial relationships are selected for a COT. A UE receives, from a base station, an indication corresponding to a COT. The indication is for at least one of a set of CORESETs, a set of QCL assumptions, a set of UL resources, or a set of spatial relations for determining a default beam. The UE determines the default beam from the base station for use during the COT based on the indication. The UE transmits or receives a transmission using the default beam.

Abstract: Apparatus, methods, and computer-readable media for facilitating full-duplex operation are disclosed herein. The disclosed techniques include using an advanced searcher. An example method for wireless communication at a first wireless device includes receiving a set of reference signals from a second wireless device. The example method also includes determining a first set of BPLs based on the set of reference signals. The example method also includes determining a second set of BPLs based on a capability of full-duplex operation with at least one BPL of the first set of BPLs. Additionally, the example method includes performing measurements for the second set of BPLs. The example method also includes communicating using full-duplex operation by transmitting or receiving via a BPL of the first set of BPLs while also performing the other of transmitting or receiving via a BPL of the second set of BPLs.
