Abstract: Certain aspects of the present disclosure provide techniques for beam refinement procedures including dynamic signaling and/or selection of beam-switching latency for beam refinement procedures using inter- and/or intra-antenna module beam switching. A method by a base station (BS) includes configuring a user equipment (UE) with one or more reference signal (RS) resource sets. Each of the one or more RS resource sets is associated with a first or second type of beam refinement procedure. The BS receives an indication from the UE of at least a first latency and a second latency, longer than the first latency. The BS dynamically selects, for each RS transmission using one of the configured resource sets, the first or second latency. The BS sends the RS transmissions at the selected latency with respect to downlink control information (DCI) triggering the RS transmissions for the first or second type of beam refinement procedure.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless node (e.g., a user equipment) may receive, from a second wireless node (e.g., a base station), a downlink signaling message indicating a synchronization signal block (SSB) grouping based at least in part on a full-duplex capability and transmission directions associated with the second wireless node. The first wireless node may configure, and the second wireless node may perform, a beam search and/or a self-interference measurement to identify at least one candidate downlink and uplink beam pair suitable for full-duplex operation based at least in part on the SSB grouping. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for configuration of resources to determine signal-to-interference-plus-noise ratio (SINR). A method that may be performed by a user equipment (UE) includes transmitting, to a base station (BS), an indication that the UE is configured with at least one capability to support a combination of a channel measurement resource (CMR) and at least one interference measurement resource (IMR), if group based beam reporting is configured, receiving a reference signal (RS) resource setting for the CMR to perform channel measurement based, at least in part, on the capability of the UE, receiving at least one RS resource setting for the at least one IMR to perform interference measurement based, at least in part, on the capability of the UE, determining at least one signal-to-interference-plus-noise ratio (SINR) parameter based on results of performing the channel measurement and the interference measurement, and transmitting the SINR parameter to the BS.

Abstract: Aspects of the present disclosure include methods, apparatuses, and computer readable media for receiving a layer 1 signaling or a layer 2 signaling indicating a subset of a plurality of physical cell identifications (PCIs) associated with a plurality of serving cells in the network, establishing a plurality of communication channels with one or more of transmission-reception points (TRPs), wherein each TRP of the one or more TRPs comprises a corresponding PCI of the plurality of PCIs, and determining one or more PCIs of the plurality of PCIs used as one or more default input cell identifications (IDs) associated with a plurality of physical processings, when no explicit configured input ID is signaled to the UE associated with the plurality of physical processings.

Abstract: In an aspect, a BS transmits a WUS that includes an indication of selected PCIs of a PCI group to a UE. The UE receives the WAS and monitors one or more configured DRX ON durations associated with the selected PCIs of the PCI group. In another aspect, a BS transmits a signal that includes dormancy status information for a set of selected PCIs to a UE. For each PCI in the set of selected PCIs indicated by the dormancy status information as associated with a dormant state, the UE refrains from PDCCH monitoring on a dormant BWP to which the respective PCI transitions. For each PCI in the set of selected PCIs indicated by the dormancy status information as associated with a non-dormant state, the UE performs PDCCH monitoring on a non-dormant BWP to which the respective PCI transitions.
