Abstract: A first network node measures cross link interference (CLI) from a transmission of a second network node for a set of one or more candidate beam pairs, each candidate beam pair of the set of one or more candidate beam pairs including an uplink beam of the first network node and a downlink beam of the second network node. The first network node provides CLI information indicating at least one of one or more preferred beam pairs or one or more non-preferred beam pairs based on a CLI measurement from the transmission, the CLI information further indicating at least a first Quality of Service (QoS) or a first priority level for uplink traffic of the first network node.

Abstract: Certain aspects of the present disclosure provide a method for wireless communications at a user equipment (UE). The UE may receive a configuration from a base station (BS). The configuration may indicate transmission parameters associated with different symbols such as sub-band full duplex (SBFD) symbols and non-SBFD symbols. For example, the transmission parameters may indicate power control parameters (e.g., a received power target value, a power control factor value, a closed-loop power control value) and a unified transmission configuration indicator (TCI) (e.g., a joint uplink and downlink TCI state, separate uplink and downlink TCI states). The UE may transmit uplink transmissions to the BS, in accordance with the transmission parameters.

Abstract: Methods, systems, and devices for wireless communications are described. The network may configure two sets of power control parameters for a user equipment (UE) so that the UE may use different uplink power control parameters for transmissions in different types of time resources associated with different interference conditions. For example, the network may indicate for a carrier which time resources are uplink time resources and which time resources are subband full-duplex (SBFD) resources, and UE may apply a first set of uplink power control parameters to transmissions in the uplink resources and a second set of uplink power control parameters to transmissions in the SBFD resources. For time division duplexing scenarios, the network may similarly configure two sets of uplink power control parameters for the UE to apply to time resources that the network identifies cause cross-link interference (CLI) and time resources that the network identifies do not cause CLI.

Abstract: 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.

Abstract: Apparatus, methods, and computer-readable media for facilitating phase jump estimation for SL DMRS bundling are disclosed herein. An example method includes receiving, from another device, first information at a first symbol of a first slot, the first slot including at least the first symbol and a first reference signal. The example method also includes receiving second information at a second symbol of a second slot, the second slot including at least the second symbol and a second reference signal, the first information and the second information being repetitions. The example method also includes generating a first reference signal copy based at least on the second reference signal and a phase jump between the first slot and the second slot. Additionally, the example method includes performing channel estimation across the first slot and the second slot based on an aggregation of the first reference signal and the first reference signal copy.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a radio link monitoring configuration for a first serving cell that indicates a configuration of a first and second set of beam-failure-detection reference signals (BFD-RSs) associated with the first serving cell and a second serving cell, respectively. The UE may measure, in accordance with the radio link monitoring configuration, one or more BFD-RSs of the first set of BFD-RSs or the second set of BFD-RSs. The UE may determine a beam failure associated with at least one of the first serving cell or the second serving cell based at least in part on measuring the one or more BFD-RSs of the first set of BFD-RSs or the second set of BFD-RSs, respectively. Numerous other aspects are described.
