A wireless device, such as a user equipment (UE), may receive first scheduling information with first resources for periodic transmissions with a first beam based on a half-duplex mode. The wireless device may receive second scheduling information for second resources associated with a second beam that is incompatible with the first beam for full duplex communication including downlink reception and uplink transmission that overlaps in time. The wireless device may adjust communication in response to the first beam being incompatible with the second beam for the full duplex communication.

Beam adjustment/cancellation rules for non-compatible UL/DL beams

Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive an indication of a sub-band full-duplex (SBFD) configuration of a cell serving the UE. The SBFD configuration may indicate a first set of resources for downlink communications and a second set of resources for uplink communications. The first set of resources and the second set of resources may include non-overlapping frequency resources in a same time interval. The UE may receive a control message that indicates a pre-emption of the first set of resources or a cancellation of the second set of resources. Accordingly, the UE may determine that downlink transmissions in at least a portion of the first set of resources are pre-empted or that uplink transmissions in at least a portion of the second set of resources are cancelled based on the control message and the SBFD configuration of the cell.

Downlink pre-emption and uplink cancellation for full-duplex systems

Methods, systems, and devices for wireless communication are described. In some systems, a user equipment (UE) may transmit a message that indicates a first quantity of calculations that the UE is capable of performing within a same time period. The first quantity of calculations may include at least one calculation that is based on one or more cross-link interference (CLI) measurements at the UE. A first quantity of reports supported by the UE may be based on the first quantity of calculations. The CLI measurements may correspond to interference at the UE based on communications by at least a second UE. The UE may transmit a second quantity of one or more reports based on the CLI measurements. The second quantity of reports may be less than or equal to the first quantity of reports based on the message.

Cross-link interference reporting for wireless communications

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may output a first configuration for a set of resources, the first configuration being associated with a time division duplexing pattern, and the first configuration configuring the set of resources to one of an uplink format, a downlink format, or a flexible format. The network node may output a second configuration configuring one or more resources, of the set of resources, to a sub-band full duplex (SBFD) format based at least in part on the one or more resources satisfying a condition. Numerous other aspects are described.

Sub-band full duplex resource configuration

Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for improving the reliability of downlink transmissions from a base station to a user equipment (UE). The UE may determine one or more preferred configurations for the base station to use to transmit multiple downlink transmissions to the UE, and the UE may transmit a recommendation of the preferred configuration(s) to the base station. The base station may then determine configurations to use for the multiple downlink transmissions based on the recommendation received from the UE, and the base station may transmit the downlink transmissions to the UE using the determined configurations. Because the UE may provide the recommendation of the preferred configuration(s) to the base station, the configurations used by the base station for the multiple downlink transmissions may be selected specifically for the UE. Thus, the reliability of the downlink transmissions may improve.

User equipment recommended configurations across different transmissions

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless node may determine, from a plurality of beams associated with the first wireless node, a set of suitable uplink beams and a set of suitable downlink beams, wherein the set of suitable UL beams and the set of suitable DL beams are suitable for full duplex communications, and transmit, to a second wireless node, an indication of the set of suitable uplink beams and the set of suitable downlink beams. Numerous other aspects are provided.

Wireless node self-interference measurements and uplink beam management for full duplex transmissions

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.
