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, information indicating a Layer 1 signal to interference plus noise ratio (L1-SINR) measurement capability of the UE. The UE may receive, from the base station, a reference signal carried on one or more resources based at least in part on the L1-SINR measurement capability. Numerous other aspects are provided.

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: This disclosure provides systems, methods, and apparatuses, including computer programs encoded on computer storage media, for wireless communication. In one aspect of the disclosure, a method for wireless communication includes shifting, based on a partial overlap between a scheduled downlink transmission occasion and a scheduled uplink transmission occasion that each include a first and second repetition, a first repetition boundary of one transmission occasion of the downlink transmission occasion or the uplink transmission occasion, and performing full duplex communication with repetition based on the shifted first repetition boundary. In some implementations, shifting includes shifting an entirety of the one transmission occasion. In some implementations, shifting the first repetition boundary changes a number of consecutive symbols included in the first repetition of the one transmission occasion. In some implementation, the method includes adding a third repetition boundary to the one transmission occasion. Other aspects and features are also claimed and described.

Abstract: Aspects described herein relate to communicating a configuration indicating resources for measuring new candidate beam pairs for full-duplex operation to facilitate measuring one or more new candidate beam pairs over the resources to determine measurement results for the one or more new candidate beam pairs, and reporting, based on a measurement result for at least one new candidate beam pair of the one or more new candidate beam pairs, the measurement result or an indication of the at least one new candidate beam pair.

Abstract: Methods, systems, and devices for wireless communications are described. Aspects of the present disclosure provide techniques for restricting beams that may lead to inter-base station interference. For example, an implicit restriction of beams may be used by a first and second base station (e.g., a victim and aggressor base station, respectively). In such cases, the first base station may indicate a period, a subband, or both, associated with one or more scheduled uplink beams that the first base station may use for receiving uplink transmissions. The second base station may select beams that avoid interference with the uplink beam(s) of the first base station. Additionally or alternatively, an explicit restriction of beams may be signaled, where the first base station may explicitly indicate a set of downlink beams associated with the second base station that are allowed (e.g., beams that avoid interference with uplink transmissions at the first base station).

Abstract: In an aspect, the present disclosure includes a method, apparatus, and computer readable medium for wireless communications at a user equipment (UE) for receiving a downlink control indicator (DCI) from a network entity; and configuring at least one physical uplink shared channel (PUSCH) transmission based on a determination that the DCI does not include the scheduling request indicator (SRI) field.

Abstract: Aspects relate to mechanisms for wireless communication devices to signal for dynamically updating the configuration of a sound reference signal (SRS) resource set. A user equipment (UE) receives from a base station, via at least one of a downlink control information (DCI) or a medium access control (MAC) control element (MAC-CE), a configuration of one or more sounding reference signal (SRS) resource sets for SRS transmission. The UE also receives an indication of an update of one or more parameters, via at least one of the DCI or the MAC-CE, for at least one SRS resource set of the one or more SRS resource sets. The UE further applies the update to at least one SRS transmission.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless node (e.g., a user equipment) may determine one or more measurements associated with a beam search performed during a downlink beam management process. The first wireless node may transmit, to a second wireless node (e.g., a base station), a report that indicates one or more candidate downlink receive beams, candidate uplink transmit beams, or candidate downlink receive and uplink transmit beam pairs suitable for full-duplex operation based at least in part on the one or more measurements. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a wireless device may select random access channel occasions (ROs) based jointly on synchronization signal block (SSB) measurements and cross-link interference (CLI) measurements. The base station may configure the wireless device with a set of SSB occasions during which to measure SSBs and a set of interference measurement occasions on which to measure CLI caused by other wireless devices. The wireless device may perform measurements on the received SSBs to determine channel quality for communications with the base station, and CLI measurements during the interference measurement occasions to determine whether CLI exceeds a threshold. The wireless device may then select a beam and an associated RO (e.g., a full duplex RO or a half duplex RO) on which to transmit the random access message using the selected beam.
