Abstract: Techniques for wireless communications are described. A first device may communicate with a second device using a first beam. Based on communicating with the second device, the first device may indicate a reference signal associated with a different beam to indicate that the different beam associated with the reference signal is preferred for subsequent communications. The reporting device may switch to the different beam based on transmitting the indication of the reference signal. Based on switching to the different beam, the reporting device may determine a communication parameter based on the indicated reference signal and communicate with the scheduling device using the second beam based on the determined communication parameter.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive an indication of a plurality of random access occasions for uplink message transmission to a base station. The UE may determine that a first portion of the plurality of random access occasions is unavailable for use by the UE as a result of the base station operating in a full duplex mode. The UE may select one or more random access occasions from a second portion of the plurality of random access occasions instead of from the first portion based at least in part on the determining. The UE may transmit a random access message to the base station during the one or more random access occasions from the second portion.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may store configurations for candidate physical cell identifiers (PCIs) that the UE may select from for inter-cell mobility. A base station or a UE or both may identify a first configuration indicating a number of configured PCIs for inter-cell mobility operations. The base station or the UE or both may identify a second configuration indicating a number of selected PCIs for inter-cell mobility operations. In some cases, the selected PCIs may be a subset of the configured PCIs. Identifying the number of configured PCIs and the number of selected PCIs by the base station and UE may be based on a capability report configured by the UE. The UE and the base station may perform an inter-cell mobility operation based on stored cell configurations associated with the configured PCIs and the selected PCIs.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive information indicating a first slot format, wherein the information indicates one or more symbols associated with a full duplex (FD) format. The UE may perform communication based on a second slot format until a time period after the reception of the information indicating the first slot format, wherein the second slot format is prior to the first slot format. The UE may perform at least one of half duplex (HD) communication or FD communication in accordance with the first slot format after the time period has elapsed. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. In some aspects, a first network entity may support one or more mechanisms according to which the first network entity may measure cross-link interference (CLI) from a second network entity and report one or more interference metrics associated with the measured CLI on a per-subband basis. The first network entity may receive an indication of a set of subbands, measure a set of interference metrics associated with the indicated set of subbands, and transmit a measurement report to indicate or otherwise convey information associated with at least a subset of the measured interreference metrics. The first network entity may receive the indication of the set of subbands from a centralized unit (CU), an operations, administration, and maintenance (OAM) entity, or a neighboring base station and may transmit the measurement report to the CU, the OAM, or the neighboring base station.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for cross-link interference (CLI) measurement in subband full-duplex (SBFD) operation. In some aspects, a first user equipment (UE) may measure CLI from a second UE during a SBFD symbol in one or more uplink subbands or in one or more downlink subbands, or in a combination thereof. The first UE and a network entity may support one or more prioritization rules associated with one or both of a capability of the first UE and potential scheduling conflicts at the first UE during the SBFD symbol. In some aspects, the first UE may measure a CLI reference signal transmitted by the second UE in one or more uplink subbands and in one or more downlink subbands allocated to the first UE to obtain an inter-subband CLI measurement and an intra-subband CLI measurement.

Abstract: A first user equipment (UE) receives a configuration of a channel state information (CSI) report from a base station. The configuration includes an indication of a sounding reference signal (SRS) or uplink demodulation reference signal (DMRS) transmitted from a second UE as an interference measurement resource (IMR). The base station configures the second UE to transmit the SRS or the uplink DMRS on the IMR. The first UE measures the IMR to determine a cross-link interference of the second UE to the first UE. The UE transmits the CSI report. The CSI report includes at least one channel characteristic that takes into account the cross-link interference of the second UE. The CSI report may include information for a plurality of CSI-RS resource indicators (CRIs), each CRI associated with a same channel measurement resource (CMR) and a different IMR corresponding to a different second UE.

Abstract: Methods, systems, and devices for wireless communications at a user equipment (UE) are described. A UE may identify one or more measurement parameters to use for input in a machine learning (ML) model. In some cases, the measurement parameters may include reference signal received power measurements or a past set of timing advance (TA) values for a specific node. The UE may predict the TA based on inputting the measurement parameters into the ML model. The UE may transmit an uplink communication from the UE to a network entity using the TA predicted from the ML model. In some examples, the UE may transmit a capability report to indicate that the UE may support autonomous update of the TA based on the predictions of the TA values produced from the ML model.
