Abstract: Methods, systems, and devices for wireless communications are described in which full-duplex communications may be configured at a serving network entity. One or more symbols of a set of symbols may be configured for full-duplex communications at the network entity, and at least a first symbol that is configured for full-duplex communications also may be configured for synchronization signal block (SSB) transmissions according to a SSB configuration. A user equipment (UE) that is configured to monitor the first symbol for a SSB may use a priority rule to determine whether to transmit an uplink communication on the first symbol, or to monitor for the SSB on the first symbol. Additionally, or alternatively, a UE may transmit capability information that indicates whether the UE supports the full-duplex operation configured in SSB symbols.

Abstract: Methods, systems, and devices for wireless communications are described that provide for full-duplex communications at both a user equipment (UE) and a serving network entity in which the UE, the network entity, or both can dynamically change from full-duplex communications to half-duplex communications. A UE may be configured for full-duplex communications for a set of symbols, and may receive an indication to switch one or more symbols to a half-duplex configuration. The half-duplex configuration may correspond to an indicated half-duplex configuration in which both the network entity and UE operate in the half-duplex configuration, or may correspond to a full-duplex configuration of the network entity in which the UE operates in half-duplex and the network operates in the full-duplex configuration. Signaling that indicates one or more symbols to be switched to the half-duplex configuration may be provided in downlink control information, medium access control signaling, or both.

Abstract: A method of wireless communication by a first user equipment (UE), includes receiving downlink signals from a network device. The method also includes receiving cross-link interference (CLI) to the downlink signals, the cross-link interference originating from a second UE. The method further includes receiving a configuration for a report of multiple differential cross-link interference metric values measured for multiple different cross-link interference resources and an absolute cross-link interference metric value measured for the different CLI resources. The method includes transmitting the report of the differential cross-link interference metric values measured for the different CLI resources.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a semi-static time and frequency configuration for subband full duplex (SBFD) operation in a symbol or slot pattern. The UE may receive a dynamic indication that adds or updates one or more SBFD symbols or slots in the symbol or slot pattern. The UE may communicate based at least in part on the semi-static time and frequency configuration and one or more of the dynamic indication or a restriction rule that restricts application of the dynamic indication. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for prioritization schemes for prioritizing colliding cross-link interference (CLI) measurements scheduled via Layer-1 signaling and a downlink transmissions scheduled according to periodic configurations. In some examples, a user equipment (UE) may prioritize downlink transmissions over CLI measurements. A UE may not monitor for or may not decode downlink control information scheduling CLI measurements in resources that the UE has a scheduled downlink reception according to a periodic scheduling configuration. In some examples, the UE may prioritize a colliding CLI measurement and downlink transmission based on an indicated priority of each, a type a CLI measurement, a type of downlink transmission, and/or a location of the UE within the cell. The UE may either monitor for the downlink transmission or perform the CLI measurement based on the priority scheme.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may transmit, and a user equipment (UE) may receive, downlink control information (DCI) that indicates a transmission configuration indication (TCI) state associated with a common bema for joint downlink and uplink communication, downlink communication only, or uplink communication only. The UE and the base station may communicate on one or more of a downlink or an uplink using the common beam associated with the TCI state indicated in the DCI. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless communication device may identify a plurality of cells associated with serving a user equipment (UE), where each cell of the plurality of cells has been either selected for serving the UE or deselected for serving the UE. The first wireless communication device may transmit an indication of the plurality of cells associated with serving the UE to a second wireless communication device, where the indication includes information indicating whether each cell of the plurality of cells has been selected for serving the UE or has been deselected for serving the UE. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. The method may include a base station establishing full-duplex communications with a first user equipment (UE) and a second UE. The method may include the first UE receiving an interference threshold from the base station, receiving a pathloss reference signal from the second UE, and determining cross-link interference between the first UE and the second UE based on the pathloss reference signal. The method may include the first UE adjusting a transmit power setting of the first UE in accordance with the cross-link interference and transmitting to the base station an uplink metric report, the uplink metric report including an uplink metric of the first UE that is based on the adjusted transmit power setting of the first UE.

Abstract: Apparatus, methods, and computer program products for PHY priority for wireless communications are provided. An example apparatus may multiplex a first uplink control information transmission based on a first uplink control information resource and a second uplink control information transmission based on a second uplink control information resource that overlaps in time with the first uplink control information resource, at least one of the first uplink control information resource and the second uplink control information resource being for full-duplex communication. The example apparatus may determine, based on applying a multiplexing rule on the full-duplex communication, whether to use the first uplink control information resource associated with a first beam or the second uplink control information resource associated with a second beam. The example apparatus may transmit a multiplexed uplink control information transmission using a determined uplink control information resource based on the multiplexing rule.
