Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may configure multiple transmission reception point (mTRP) operation in a manner that enables a user equipment (UE) to measure inter-UE cross-link interference (CLI) for each downlink receive beam that corresponds to a respective TRP that communicates with the UE in a duplexing mode with dynamic interference conditions (for example, CLI and/or self-interference). For example, to support mTRP operation, the network node may transmit, to the UE, a CLI configuration that indicates a respective CLI measurement resource set for each TRP that is configured to communicate with the UE, where each CLI measurement resource set may include an interference measurement resource (IMR) set associated with a respective TRP, thereby configuring the UE to measure and report a CLI level for each channel measurement resource (CMR) associated with a TRP that communicates with the UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first network entity may receive measurement reference signals from a second network entity. The first network entity may measure cross-link interference (CLI) based at least in part on the measurement reference signals. The first network entity may transmit a recommendation for downlink transmit power adjustment of the second network entity, based at least in part on the CLI. The first network entity may communicate based at least in part on a response to the recommendation or a feedback rule for the recommendation. Numerous other aspects are described.

Abstract: A UE may receive a time resource pattern including a first set of time resources and a second set of time resources that are non-overlapping in a time domain with the first set of time resources, each time resource of the first set of time resources configured with a subband full-duplex (SBFD) configuration, and each time resource of the second set of time resources configured with a non-SBFD configuration. A UE may receive a synchronization signal block (SSB) configuration including one or more periodic SSB occasions. A UE may adjust at least one of an SSB measurement or an uplink transmission in one or more symbols including an SSB occasion, of the one or more periodic SSB occasions, overlapping with a time resource of the first set of time resources.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive control information associated with dynamic subband full duplex (SBFD), wherein the control information indicates whether a downlink reception outside a semi-statically configured downlink subband or an uplink transmission outside a semi-statically configured uplink subband is allowed, or whether a symbol is an SBFD symbol or a non-SBFD symbol. The UE may perform a communication based at least in part on the control information. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described to enable one or both of a base station or a user equipment (UE) to identify one or more physical cell identifiers (PCIs) for a scheduled communication, using an association between the one or more PCIs and a control resource set (CORESET), for example, used to transmit a grant scheduling the communication. The base station may identify a mapping between one or more PCIs associated with a communication and may transmit, to the UE, a grant scheduling the communication on a CORESET associated with the one or more PCIs. The UE may identify a mapping between the CORESET and the one or more PCIs associated with the communication based on receiving the grant in the CORESET. The UE and the base station may communicate a message scheduled by the grant using parameters associated with the one or more identified PCIs.

Abstract: Certain aspects of the present disclosure provide techniques for cross link interference (CLI) resource reporting. An example method, performed at a first network entity, includes receiving a report, from a first user equipment (UE), indicating information regarding one or more first cross-link interference (CLI) resources, wherein the one or more first CLI resources correspond to one or more transmission beams associated with at least one second UE and are associated with lower levels of measured CLI than one or more second CLI resources, and performing one or more actions, based on the information.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling that indicates a set of cross-link interference (CLI) resources to monitor for inter-UE CLI and a set of separate inter-UE CLI metrics for the UE to report for the set of CLI resources. The control signaling may include at least a channel state information (CSI) resource configuration, or a CSI report configuration, or a CLI resource configuration, or a CLI report configuration, or a CSI aperiodic trigger state configuration, or a CLI aperiodic trigger state configuration, or a combination thereof. The UE may monitor the set of CLI resources to determine the set of separate inter-UE CLI metrics for the set of CLI resources. The UE may transmit a measurement report that indicates the set of separate inter-UE CLI metrics for the set of CLI resources.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration, from a network, associated with a downlink transmission in one or more subband full duplex (SBFD) symbols. Accordingly, the UE may selectively transmit an uplink transmission in the one or more SBFD symbols based at least in part on the configuration. Additionally, or alternatively, the UE may receive a configuration, from the network, associated with a random access channel occasion in one or more SBFD symbols. Accordingly, the UE may selectively receive a downlink transmission in the one or more SBFD symbols based at least in part on the configuration. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) and a network entity may support measurement and reporting of channel state information (CSI) in association with the communication of CSI reference signals (CSI-RSs) via subband full duplex (SBFD) time intervals. For example, the network entity may indicate, to the UE, a linkage of two or more CSI-RS resources across two or more downlink subbands of a SBFD time interval. The UE may transmit a report to the network based on two or more CSI-RSs received via the linked CSI-RS resources, where the report includes a single measurement metric based on the CSI-RS resources being linked. Additionally, or alternatively, the network entity may indicate respective CSI measurement configurations associated with SBFD and non-SBFD time intervals. The UE may report CSI for respective CSI-RSs received via SBFD or non-SBFD time intervals in accordance with respective measurement configurations.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a channel state information (CSI) report configuration that indicates a dedicated UE-to-UE cross-link interference (CLI) resource as an additional interference measurement resource (IMR). The UE may transmit, based at least in part on the CSI report configuration, a CSI report that implicitly captures CLI in a CSI report quantity of the CSI report. Numerous other aspects are described.
