Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit, to a base station, a UE capability to receive a first portion of a tracking reference signal (TRS) and a second portion of the TRS, the first portion and the second portion associated with a TRS pattern. The UE may receive, from the base station, an indication of the TRS pattern, where the TRS pattern includes the first portion of the TRS pattern and the second portion of the TRS pattern. The UE may receive one or more TRSs according to the first portion of the TRS pattern and the second portion of the TRS pattern.

Enhanced tracking reference signal patterns

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.

FD mode dependent UCI multiplexing

Methods, systems, and devices for wireless communications are described. Techniques described herein relate to schemes for managing an overlap of at least part of a tracking reference signal (TRS) with an uplink subband or a guard band in a subband full duplex (SBFD) slot or symbol. In some examples, if a user equipment (UE) and/or a network entity determines that at least a portion of a TRS is scheduled for reception in an uplink subband or a guard band of an SBFD slot or symbol, the UE and/or the network entity may: drop the TRS, puncture the portion of the TRS that overlaps with the uplink subband or the guard band; or may shift the frequency position of the TRS such that the TRS is scheduled within the downlink subband(s) of the SBFD slot or symbol.

Tracking reference signals in full duplex operation

Methods, systems, and devices for wireless communications are described. For example, a communication device may receive control signaling (e.g., a broadcasted control signal) from another communication device. The control signaling may indicate beam information for one or more beams of a set of beams. The one or more beams may correspond to the serving cell or one or more neighboring cells. The beam information may include one or more metrics associated with each of the one or more beams. As such, the communication device may determine that a metric associated with each of the one or more beams satisfies a threshold, select the beam, and communicate using the selected beam. In some other examples, the beam-specific information may include beam measurement offsets for one or more beams. In such examples, the communication device may select a beam based on the beam measurement offsets and perform communications using the selected beam.

Beam-specific key performance indicator indication for serving node selection

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.
