Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, an indication of at least one first beam and at least one first antenna panel of the UE, to use for one or more first transmissions, and of at least one second beam and at least one second antenna panel of the UE, to use for one or more second transmissions. Accordingly, the UE may communicate the one or more first transmissions, with the base station, using the at least one first beam and the at least one first antenna panel. Additionally, the UE may communicate the one or more second transmissions, with the base station, using the at least one second beam and the at least one second antenna panel.

Abstract: When a beam failure is detected, appropriate actions may be taken to recover the connection. A beam failure recovery request may be sent by a user equipment (UE) apparatus to initiate the recovery of the connection. The UE detects a beam failure for at least one active downlink and uplink beam pair for full duplex communication with a secondary cell (SCell). The UE transmits a beam failure recovery request (BFRQ) for the SCell to a base station using an uplink resource of the SCell or a primary cell (PCell) based on a layer 1 signal to interference and noise ratio (L1-SINR) measurement for the at least one active downlink and uplink beam pair of the SCell.

Abstract: A User equipment (UE) receives a control resource set (CORESET) configuration for a full duplex CORESET. The UE performs a measurement for full duplex operation based on at least one of a downlink beam or an uplink beam for full duplex beam failure detection based on one or more quasi co-location (QCL) relationships to one or more transmission configuration indication (TCI) states of the CORESET based on an absence of a configuration of a reference signal for the full duplex beam failure detection.

Abstract: Aspects of the present disclosure provide a method for wireless communications by a user equipment (UE). The method generally includes receiving signaling configuring multiple candidate target physical cell identifiers (PCIs) of at least one candidate target cell that supports physical (PHY) layer or medium access control (MAC) layer mobility signaling, participating in a handover procedure to a target cell associated with a selected one or more of the candidate target PCIs based on PHY layer or MAC layer mobility signaling, receiving, from the target cell, a response message indicating success of the handover procedure, and terminating activity with one or more source PCIs after receiving the response message.

Abstract: Aspects of the present disclosure provide a technique for wireless communications by a user equipment (UE). The UE receives signaling configuring multiple candidate target physical cell identifiers (PCIs) of at least one candidate target cell that support physical (PHY) layer or medium access control (MAC) layer mobility signaling. The UE participates in a handover procedure to a target cell associated with a selected one or more of the candidate target PCIs based on the PHY layer or the MAC layer mobility signaling. The UE modifies a configuration for at least one cell group (CG), wherein the one or more of the candidate target PCIs are associated with component carriers (CCs) of the at least one CG.

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: 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.
