The present disclosure provides for a configuration that enables an apparatus to determine beam pairs for full duplex communication based on a cross-link interference procedure. The apparatus determines a subset of receive beams based on a beam measurement process, where each receive beam is associated with a different antenna array panel. In some aspects, the apparatus performs a channel measurement process based on the subset of receive beams. The apparatus sweeps through transmitted sounding reference signals from a same transmit beam corresponding to each receive beam of an antenna array panel and receives the transmitted sounding reference signals incrementally through other receive beams associated with other antenna array panels. The apparatus measures a self-interference for at least one beam pair of the subset of receive beams based on a received sounding reference signal. The apparatus selects one or more beam pairs based on a self-interference measurement or a signal-to-interference-plus-noise ratio.

Reusing a cross link interference framework for self-interference measurement

Methods, systems, and devices for wireless communications are described. A first user equipment (UE) (e.g., 'victim' UE) may receive control signaling indicating a cross-link interference (CLI) reporting configuration associated with a set of CLI resources, where the CLI resources are associated with varying levels of CLI at the first UE. The first UE may perform CLI measurements on signals received from a second UE (e.g., “aggressor” UE) within the set of CLI interference resources based on the CLI reporting configuration. The first UE may then transmit, based on the CLI measurements, a CLI report identifying a CLI resource from the set of CLI resources, wherein the CLI resource is associated with a CLI measurement that fails to satisfy a CLI threshold, or wherein the CLI resource is associated with a lower level of CLI as compared to other CLI resources within the set of CLI resources.

Techniques for CLI reporting trigger conditions

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may transmit a channel estimation granularity indication that specifies a channel estimation granularity associated with generating channel state information (CSI) that is based at least in part on a full-duplex configuration. The network node may receive the CSI associated with the channel estimation granularity indication. Numerous other aspects are described.

Channel state information reference signal estimation granularity configuration in full-duplex

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may transmit, to another network node, an indication of a duplex capability associated with the network node. The network node may receive, from the other network node, a configuration of a resource associated with a communication by the network node, wherein the configuration is based at least in part on the indication of the duplex capability associated with the network node. The network node may perform the communication in accordance with the configuration of the resource. Numerous other aspects are described.

Inter-node indication of full duplex capability

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information indicative of a subband full duplex (SBFD) configuration for communicating, based on a half duplex (HD) configuration at the UE, with a full duplex network node associated with a time division duplexing (TDD) carrier, the SBFD configuration corresponding to one or more bandwidth parts (BWPs) associated with a plurality of resources comprising at least one HD resource and at least one SBFD resource, the one or more BWPs comprising at least one of a downlink (DL) BWP or an uplink (UL) BWP. The UE may communicate based on the configuration information. Numerous other aspects are described.

Bandwidth part configurations for mixed half duplex and subband full duplex communications

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may receive an indication of one or more of: an identifier of a neighbor user equipment (UE) associated with a neighbor network node, a location and mobility status of a UE served by the network node, or beam adaptation information of the UE served by the network node. The network node may perform an interference mitigation for the UE served by the network node based at least in part on the indication of one or more of: the identifier of the neighbor UE, the location and mobility status of the UE, or the beam adaptation information of the UE. Numerous other aspects are described.

Interference mitigation for a user equipment

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive scheduling information for an uplink transmission and a downlink reception in full-duplex. The UE may transmit, in a symbol prior to a resource associated with the uplink transmission, a reference signal. The UE may perform at least one of the uplink transmission or the downlink reception based at least in part on a measurement result associated with the reference signal. Numerous other aspects are described.

Pilot symbol for scheduled uplink occasion

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of whether a rate match pattern indicates a location of an uplink sub-band and at least one guard band for sub-band full duplex communication, the rate match pattern identifying resources that are to be avoided for downlink data communication. The UE may communicate according to the rate match pattern based at least in part on the indication. Numerous other aspects are described.

Indicating sub-band locations for sub-band full duplex communication

Methods, systems, and devices for wireless communications are described. In some aspects, a user equipment (UE) and a network entity may support one or more signaling-based mechanisms according to which the network entity may inform the UE of which time and frequency resources may be used for full-duplex communication. The network entity transmit a first message to configure multiple resource block (RB) sets for the UE, where each RB set is associated with unique identifying information. To inform the UE of which time and frequency resources may be used for full-duplex communication, the network entity may transmit a second message that indicates one or more slot formats on a per RB set basis. As such, the network entity may schedule the UE for full-duplex communication in accordance with indicating that overlapping symbols of a first RB set and a second RB set are allocated for uplink and downlink, respectively.

Techniques for slot format configuration per resource block set for subband full-duplex operation

A method, a computer-readable medium, and an apparatus are provided for wireless communication including random access between a base station and a user equipment (UE). The UE transmits a beam report comprising beam measurement information to the base station and transmits a first random access message to the base station for reception using one or more beams based on a random access measurement that is different than the beam measurement information comprised in the beam report. The UE monitors for a second random access message from the base station using multiple beams, the beams being selected based on the beam report.

Beam sweep based random access msg 2

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.

Cross-link interference (CLI) measurement in subband full-duplex (SBFD) operation

A UE receives information indicating a set of slots or symbols for a subband full duplex (SBFD) operation. The UE also receives a configuration of an SBFD format including at least a first subband for uplink communication and a second subband for downlink communication. The UE further receives an indication that indicates for the UE to update the SBFD format for at least a subset of the set of slots or symbols.

Signaling to indicate flexible uplink or downlink subbands

Aspects of the present disclosure provide techniques for sub-band conversion or cancellation for dynamic scheduling of sub-band full duplex (SBFD) operations between the base station and UEs. The capability to communicate via simultaneous UL and DL transmissions through dynamic scheduling allows for increased uplink duty cycle leading to latency reduction (e.g., it is possible to receive DL signal in an UL only slots, which can enable latency savings) and improved uplink coverage. Additionally enabling flexible and dynamic UL and DL resource adaptation in accordance with techniques of the present disclosure also provide enhanced system capacity, resource utilization, and spectrum efficiency.

Methods and apparatus for dynamic scheduling of sub-band full duplex communications

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling (e.g., from a network entity) indicating a CLI measurement resource and an associated transmission configuration indicator (TCI) state. The UE may generate and transmit a CLI report to the network entity using the CLI measurement resource and the beam associated with the indicated TCI state. In some cases, the control signaling may indicate to use the same TCI state as another dedicated downlink channel configured for the UE. In some cases, the control signaling may indicate a unified TCI state to apply for the CLI measurement. In some cases, a UE may be configured to communicate with multiple transmission and reception points (TRPs). The TCI state to apply to the CLI measurement may be based on the TRP scheduling the CLI measurement.

Unified transmission configuration indicator state indication for cross-link interference measurement

Certain aspects of the present disclosure provide techniques for guard period configuration between subband full duplex and half duplex symbols and slots. An example method that may be performed at a user equipment (UE) includes obtaining an indication of a guard period during which a cell in which the UE is communicating will switch between subband full duplex (SBFD) communications and half duplex (HD) communications; and performing one or more actions during the guard period, in accordance with the indication.
