Abstract: Methods, systems, and devices for wireless communications are described. A network entity, such as a base station, may receive, from a first network entity, a broadcast indicating a downlink control channel transmission pattern associated with the first network entity. The network entity may monitor a plurality of receive beams for a plurality of downlink control channel transmissions from the first network entity according to the downlink control channel transmission pattern and may select a communication beam according to one or more cross-link interference (CLI) measurements associated with one or more of the plurality of receive beams in accordance with the monitoring. The network entity may communicate with a user equipment using the selected communication beam and a first set of resources that at least partially overlap in time and frequency with a scheduled communication at the first network entity. The network entity may experience or may cause the measured CLI.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for implementing signaling for indicating a scheduled full duplex (FD) uplink (UL) and downlink (DL) traffic scheduling combination for differentiation of FD traffic. In some aspects, a BS may transmit a downlink control information (DCI) message that includes an indication of the scheduled FD UL and DL traffic scheduling combination. The FD UL and DL traffic scheduling combination may identify scheduled UL and DL transmissions for FD mode operation. The UE may receive the DCI message and identify the scheduled FD UL and DL traffic scheduling combination. In some aspects, the BS may provide a DCI message to the UE that indicates whether a DL transmission is being scheduled that at least partially overlaps with a scheduled UL transmission. The UE may initiate a power save mode based on the received DCI message.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may apply an uplink muting maximum power reduction (UM-MPR) to uplink transmissions based on receiving an activation for uplink muting (e.g., activation of a muting pattern). The UE may apply the UM-MPR to an uplink transmission associated with a first muting pattern based on the first muting pattern being from a set of muting patterns, or from a subset of the set of muting patterns. In some examples, the UE may identify a value of the UM-MPR for the uplink transmission based on the first uplink muting pattern applied to the uplink transmission, a waveform type of the uplink transmission, a modulation scheme of the uplink transmission, a type of uplink resource allocation of the uplink transmission, or any combination thereof.

Abstract: Methods, systems, and devices for wireless communications are described. A network may configure a user equipment (UE) with a time duration pattern, and may further indicate (e.g., via control signaling) which time intervals (e.g., slots or symbols) of the time duration pattern are designated as full duplex time intervals. The network may indicate a full duplex time interval on a configured downlink symbol, a configured uplink symbol, or a configured flexible symbol. The network may further indicate frequency resources (e.g., an uplink subband, a downlink subband, etc.) via which the UE is to perform the full duplex communication during the indicated time intervals. The control signaling may include an indication of a full duplex mode for each of the time intervals. Multiple transmission receive points (TRPs) may communicate to determining which TRP will schedule uplink signaling and which TRP will schedule downlink signaling in the full duplex time interval.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a network node, capability information associated with two or more communication modes of a plurality of communication modes, the two or more communication modes comprising at least one full duplex (FD) mode. The UE may receive, from the network node, configuration information associated with the two or more communication modes, the configuration information indicating at least two sets of parameter values, wherein each set of parameter values is associated with a respective communication mode of the two or more communication modes. The UE may communicate with the network node based at least in part on the at least two sets of parameter values. Numerous other aspects are described.

Abstract: 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 semi-static time and frequency subband full-duplex (SBFD) configuration associated with at least one resource semi-statically configured as an SBFD resource, wherein the at least one resource comprises a time and frequency resource. The UE may receive a dynamic SBFD update indication associated with the at least one resource. The UE may perform a cross link interference (CLI) measurement task associated with an updated CLI resource based on the dynamic SBFD update indication. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an UE may transmit, to a first network node, capability signaling associated with an uplink resource muting, the capability signaling indicating that the UE is capable of muting an uplink resource during a transmission of a reference signal from a second network node for an inter-network-node cross-link interference (CLI) measurement. The UE may receive, from the first network node, an indication associated with the uplink resource muting in accordance with the capability signaling. Numerous other aspects are described.

A network entity may receive control information that indicates parameter information for reporting cross-link interference (CLI). The parameter information may include first parameter information associated, in the control information, with a first type of transmission time interval (TTI) or the parameter information may include second parameter information associated, in the control information, with a second type of TTI. The network entity may receive one or more CLI reference signals during one or more TTIs of the first type of TTI or the second type of TTI. The network entity may transmit a report including information indicative of CLI. The information indicative of the CLI may be associated with the one or more CLI reference signals.

Abstract: A user equipment (UE) may obtain high-priority data (e.g., low latency data) to be transmitted to a base station. In some scenarios, the base station may be transmitting downlink transmissions to the UE or to a different UE, or may be receiving uplink transmissions from the UE or from the different UE. The described aspects enable the UE to timely transmit the high-priority data in these scenarios. In one example, the described aspects enable the UE to transmit, to the base station, while the base station performs one or more scheduled downlink transmissions to the UE or to the different UE, at least one of the high-priority data via a first uplink beam from a set of uplink beams for unscheduled uplink transmissions or an unscheduled data indication indicating that the high-priority data is to be transmitted without an uplink grant.
