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: 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: 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.

Abstract: In an aspect, a network device (e.g., BS, core network component, etc.) determines a self-interference measurement (SIM) configuration associated with null-forming at a wireless device (e.g., UE or BS), the null-forming associated with steering at least one receive beam of the wireless device and/or at least one transmit beam of the wireless device away from one or more external sources of self-interference. The network device transmits the SIM configuration to the wireless device. The wireless device performs at least one null-forming procedure in accordance with the SIM configuration.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a configuration message that is associated with a full duplex transmission mode. The configuration message includes at least one indicator of a resource for channel measurement, where the at least one indicator of the resource for channel measurement is associated with a plurality of resources for interference measurements that include at least one resource for self-interference measurement. Additionally, or alternatively, the configuration message includes at least one indicator of a format for a sub-band report, where the format indicates that the sub-band report is to include at least one of reference signal received power, signal-to-interference-and-noise ratio, or a combination thereof. The UE may transmit, to the base station, at least one report based at least in part on the configuration message. Numerous other aspects are described.

Abstract: Aspects relate to selecting a physical cell identifier (PCI) that a user equipment (UE) uses to obtain a timing reference for a mobility measurement. A serving base station (BS) associated with multiple cells may select a set of these cells as candidate cells for a UE and send to the UE a set of candidate PCIs associated with those cells (e.g., one PCI for each cell). The BS may select a subset of the candidate cells to serve to the UE and indicate to the UE the corresponding subset of PCIs. The UE may select a PCI from the set of candidate PCIs (or from the subset of PCIs) to use for obtaining a timing reference for a synchronization signal block (SSB) measurement. The UE may select a PCI based on a defined rule. The UE may select a PCI based on signaling from the BS.

Abstract: Some aspects described herein relate to configuring user equipment (UE) for performing sidelink (SL) random access (RA) procedures, which may include assistance from a base station or other network component. One or more parameters for performing a random access procedure with a second UE over a sidelink can be received from a base station. A first random access message can be transmitted to the second UE as part of the random access procedure over the sidelink. A second random access message can be received, from the second UE, in response to transmitting the first random access message, and as part of the random access procedure over the sidelink, where at least one of transmitting the first random access message or receiving the second random access message are based on the one or more parameters.
