Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine whether a sidelink synchronization signal (SLSS) is received from a synchronization reference (SyncRef) UE during a measurement evaluation period, the measurement evaluation period being based at least in part on a quantity of sidelink synchronization signal block (S-SSB) periods in which the SLSS from the SyncRef UE is not available. The UE may perform an initiation or a cease of an SLSS transmission of the UE based at least in part on whether the SLSS is received from SyncRef UE during the measurement evaluation period. Numerous other aspects are described.

In some aspects, a user equipment (UE) may receive, from a network node via a source cell, a medium access control (MAC) control element (MAC-CE) triggering a handover from the source cell to a target cell in an activated cell set configured for Layer 1/Layer 2 (L1/L2) mobility. The UE may transmit, to the network node via the target cell, a physical random access channel (PRACH) to initiate an aperiodic contention-free random access (CFRA) procedure in the target cell in a random access channel (RACH) occasion in a PRACH slot associated with a slot offset indication received from the network node.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information indicating a frequency division multiplexing (FDM) parameter associated with a random access procedure. The UE may transmit a Message 1 (Msg1) or a Message A (MsgA) on one or more resources in accordance with the configuration information and based at least in part on the one or more resources having a valid status, wherein at least one of the FDM parameter or the valid status is based at least in part on the random access procedure utilizing a narrowband channel bandwidth. 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 an indication that associates a first synchronization signal block (SSB) to a first SSB group and a second SSB to a second SSB group, the first SSB group and the second SSB group associated with a single physical cell identifier (PCI). The UE may receive one or more scheduling indications that schedule reception of the first SSB, on a first set of one or more time domain resources, and schedule reception of a downlink transmission, on a second set of one or more time domain resources that at least partially overlap with the first set of one or more time domain resources, via a beam associated with the second SSB of the second SSB group.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. Various aspects relate generally to anchor cell management for a synchronization signal block (SSB)-less secondary cell (SCell). In some aspects, an anchor cell in a different frequency band from an SSB-less SCell may be used for downlink beam management of the SSB-less SCell. A UE may report, to a network node, reference signal received power (RSRP) measurements for a plurality of downlink reference signals transmitted via the anchor cell, and the network node may determine a downlink beam for the SSB-less SCell based at least in part on the RSRP measurements. The UE may receive a configuration of the SSB-less SCell, and the configuration may indicate the anchor cell associated with the SSB-less SCell. The UE may receive an activation indication that activates the SSB-less SCell for the UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. A UE capability for a multiple physical downlink shared channel (PDSCH) scheduling may be signaled from a UE to a network entity. A UE capability signaling may indicate whether the UE supports a multiple PDSCH scheduling being associated with a same time domain resource allocation (TDRA) and/or a same frequency domain resource allocation (FDRA). The network node may schedule the multiple PDSCHs, via a multiple user multiple-input multiple-output (MU-MIMO) PDSCH scheduling or a multiple downlink control information (multi-DCI) multiple transmission reception point (mTRP) PDSCH scheduling, based at least in part on the UE capability signaling. The network entity may guarantee that co-scheduled PDSCHs have the same TDRA and/or the same FDRA, which may be based at least in part on the UE capability signaling.

Abstract: Aspects relate to activation of a cell (e.g., an SCell) based on measurements made by a user equipment (UE) when the cell is not activated with respect to (e.g., as a secondary cell for) the UE (e.g., the cell is deemed by the network as an unknown cell for that UE). In this case, when the network requests the UE to conduct measurements with respect to that cell (e.g., in conjunction with activation of the cell), the UE may report information based on the measurements the UE conducted when the cell was not activated with respect to that UE.
