Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently performing measurements and other functions in preparation for communicating with a base station on a secondary cell (SCell). In particular, a user equipment (UE) may switch to a certain bandwidth part (BWP) (e.g., a dormant BWP) on an SCell when the SCell is deactivated, and the UE may perform the appropriate measurements and functions on this BWP (e.g., based on reference signals received on this BWP). In some cases, the UE may determine to switch to the BWP for performing the appropriate measurements and functions based on an inactivity timer expiring or based on an indication from a base station (e.g., on a primary cell (PCell)). Accordingly, once the UE activates the SCell for communications with a base station, the latency associated with preparing for communicating on the SCell may be reduced.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for supporting an interface between a system that implements sensitive networking (TSN) and a wireless communications system. In one aspect, a network entity, which may be configured to communicate over the wireless communications system, may interface with one or more TSN bridges of the TSN system. The network entity may share timing information with a centralized network configuration (CNC) entity of the TSN system and may perform a time domain mapping between a first clock used by the CNC entity and a second clock used by the network entity. For example, the network entity may map absolute times using a clock drift between the first clock and the second clock and may convert time durations using a cumulative rate ratio between the first clock and the second clock.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may generate a report for one or more two-step random access channel (RACH) procedures between the UE and a base station (BS), wherein the RACH report includes at least one of an indication of a quantity of message A (MsgA) payloads transmitted during the one or more two-step RACH procedures on each beam of one or more beams associated with the BS, an indication of one or more parameters associated with each MsgA communication transmitted during the one or more two-step RACH procedures, or an indication of whether a respective signal strength for each beam, associated with the one or more two-step RACH procedures, satisfies a signal strength threshold. The UE may transmit the report to the BS. Numerous other aspects are provided.

Abstract: Aspects described herein relate to requesting suspending of a data session of a first when a device capable of communicating over multiple subscriptions switches from an active communication state if the first network to an active communication state in a second network. The device can also request resuming the data session based on switching back to active communication state with the first network.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may determine to transmit a pre-allocated uplink (UL) grant to a user equipment (UE), wherein the pre-allocated UL grant includes: a secondary node (SN) transmission configuration indicator (TCI) list, and a type 1 configured grant (CG). The base station may transmit, to the UE, the pre-allocated UL grant based at least in part on determining to transmit the pre-allocated UL grant. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for a floating synchronization signal block measurement timing configuration (SMTC) for SSB-based radio resource management (RRM) in asynchronous networks, such as new radio (NR). A base station (BS) determines a floating SMTC for measurement of a target cell and provides the floating SMTC to at least one user equipment (UE) in the serving cell, wherein the target cell and the serving cell are asynchronous. The BS determines a measurement gap that covers the floating SMTC. The UE monitors in the measurement gap for a SSB transmission of the target cell based on the floating SMTC.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may detect a trigger to initiate determination of a performance parameter for a packet data convergence protocol (PDCP) duplication procedure associated with a PDCP instance. The wireless communication device may receive packets of the PDCP instance via multiple radio link control (RLC) entities according to the PDCP duplication procedure. The wireless communication device may determine the performance parameter based at least in part on whether packets of the PDCP instance are successfully received via one or more RLC entities of the multiple RLC entities. Numerous other aspects are provided.
