Abstract: Methods, systems, and devices for wireless communication are described. For example, a user equipment (UE) may indicate to a network node whether it is capable of supporting a subband full duplex (SBFD) configuration associated with multiple downlink (DL) subbands. For instance, the UE may indicate whether it supports more than one DL subband within one or more carriers associated with a SBFD operation. The UE may receive signaling from a network node indicating a SBFD configuration based on the capability signaling. The SBFD configuration may configure a first set of resources with a single DL subband and a single UL subband, a second set of resources with a single UL subband and multiple DL subbands, or both. The UE and the network node may communicate with each other according to the SBFD configuration.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a control message indicating configuration information associated with one or more sub-band full-duplex (SBFD) symbols or slots, wherein the configuration information indicates both uplink resources and downlink resources within at least one SBFD symbol or slot of the one or more SBFD symbols or slots. In some cases, the UE may select both the uplink resources and the downlink resources for the at least one SBFD symbol slot of the one or more SBFD symbols or slots based on a capability of the UE. Additionally, the UE may communicate via both the uplink resources and the downlink resources during the at least one SBFD symbol or slot of the one or more SBFD symbols or slots based on the selection.

Abstract: Methods, systems, and devices for wireless communication are described for full-duplex communications using shared radio frequency spectrum. An uplink user equipment (UE) may be scheduled for an uplink transmission in a full-duplex channel occupancy time (COT), concurrently with one or more downlink transmissions of a downlink UE using the same wireless resources. Prior to transmitting the uplink communications, the uplink UE may perform a listen-before-talk (LBT) procedure, may provide an indication that LBT has passed, and then transmit the uplink communication. The network entity may monitor for the indication from the uplink UE and, upon detection, may continue to transmit a downlink grant to the downlink UE. If the network entity does not detect a signal from the uplink UE, it may transmit a different uplink grant to a different uplink UE, or may adjust the downlink transmission to use different resources or transmission parameters.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a capability message indicating that the UE supports performing inter-UE cross-link interference (CLI) measurements in an uplink subband and in at least one downlink subband during one or more overlapping subband full-duplex symbols. The UE may receive, based at least in part on the capability message, a measurement resource configuration for performing the inter-UE CLI measurements in the uplink subband and the at least one downlink subband. The UE may transmit, according to the measurement resource configuration, a measurement report message indicating a measurement result for the inter-UE CLI measurements.

Abstract: Methods, systems, and devices for wireless communications are described. For instance, a first network entity may receive, from a second network entity, first control information that includes first information and second information, where the first information is indicative of one or more interference measurement resources for measurement of cross-link interference and the second information may be indicative of a set of hypotheses for one or more CLI determinations. The first network entity may transmit, to the second network entity, a report that includes respective CLI information for two or more of the plurality of hypotheses, where the respective CLI information for the two or more hypotheses is based on the first information indicative of the one or more interference measurement resources.

Abstract: Certain aspects of the present disclosure provide techniques related to cross link interference (CLI) resource capability. An example method, performed at a user equipment (UE), includes outputting, for transmission, signaling indicating a quantity of resources the UE is capable of supporting, per a time unit or per a frequency unit, for measurement of at least cross link interference (CLI), obtaining a configuration in accordance with the indicated quantity of resources, measuring the CLI in accordance with the configuration, and outputting, for transmission, a CLI report based on the measuring.

Abstract: Method and apparatus for wideband PRG across a plurality of downlink subbands. The apparatus transmits, to a network entity, a UE capability indicating support for at least wideband PRG with non-contiguous frequency resources across a plurality of downlink subbands. The apparatus communicates with the network entity based on the wideband PRG. The apparatus may process each downlink subband separately without joint decoding in response to the UE capability indicating the support for the different precoding across the plurality of downlink subbands. The apparatus may process each downlink subband with joint decoding in response to the UE capability indicating the support for the same precoding across the plurality of downlink subbands. The apparatus may receive, from the network entity, a precoding indication indicating that the precoding across the plurality of downlink subbands is different or the same.

Abstract: Certain aspects of the present disclosure provide a method for wireless communications at a user equipment (UE). The UE may transmit an indication of a limit on a number of switching points (or transition points) between one or more first symbols configured for sub-band full duplex (SBFD) communications and one or more second symbols configured for non-SBFD communications, within a period of time. The UE may receive a configuration for the SBFD communications, which is in accordance with the indication.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless communications system may employ subband full-duplex (SBFD). In SBFD resources, a first user equipment (UE) may experience cross link interference (CLI) from a second UE if the second UE transmits using a frequency that is similar to a frequency of the subbands used by the first UE. The network may configure a CLI measurement resource in an SBFD time resource and may indicate in which subbands to measure CLI. The network may also indicate the reporting quantities (e.g., whether to report CLI measurement information per subband or combined per communication direction). CLI measurements may be generated in a subband manner. A CLI measurement for a CLI subband that overlaps with different subbands may be generated for the uplink subband only, may be generated for both the uplink subband and the guard band, or may be skipped.
