Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may establish, by a first subscription of the UE, a connection to a first network entity using two transmit (Tx) chains of the UE. The UE may receive, by a second subscription of the UE, a paging message from a second network entity. The UE may receive, by the first subscription from the second subscription, a request for the first subscription to enter a mode that supports one Tx chain. The UE, by the first subscription, may reduce the two Tx chains to the one Tx chain for the first subscription. The UE may perform, by the second subscription to the second network entity, the connection setup based at least in part on the first subscription reducing the two Tx chains to the one Tx chain. Numerous other aspects are described.

Abstract: A method for wireless communication at a user equipment (UE) and related apparatus are provided. In the method, the UE identifies the cell type of a cell based on the support for the UE operating with reduced capability. The cell type may be the reduced-capability (RC) type, indicating the support for the UE operating with the reduced capability, the fallback (FB) type, indicating a lack of support for the UE operating with the reduced capability and support for establishing a connection with the UE operating with the reduced capability, and the neither (N) type, indicating the lack of support for the UE operating with the reduced capability and a lack of support for establishing a connection with the UE operating with the reduced capability. The UE further manages a connection between the UE and the cell based on the cell type.

Abstract: Apparatus, methods, and computer-readable media for facilitating network slice based reselection using machine learning are disclosed herein. An example method for wireless communication at a UE includes predicting a next active PDU session of two or more PDU sessions based on next connection setup times for each PDU session. The next connection setup times may be estimated based on connection setup events occurring over a period. The example method also includes selecting a frequency channel to camp on based on the next active PDU session.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that one or more threshold criteria are satisfied, wherein the one or more threshold criteria include at least one of a first value for an uplink grant rate, a second value for a buffer size, or a third value for a packet data convergence protocol discard rate, wherein the one or more threshold criteria relate to a network condition with less than a reference uplink throughput and greater than a reference downlink throughput. The UE may transmit information identifying one or more adjusted measurement values based at least in part on the determination of the one or more threshold criteria. Numerous other aspects are described.

Abstract: Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for synchronizing a UE's timing for sidelink communications with one or more other UEs. The techniques may be used, for example, in NR V2X systems to maintain sidelink timing synchronization when a UE is outside the coverage area of a synchronization source such as a global navigation satellite system (GNSS).

Abstract: The present disclosure relates to a user equipment (UE) dynamically adjusting a non-access stratum (NAS) timer. Specifically, the UE may determine operation in a wideband and support of an extended coverage (EC) restriction. The UE may further identify a duration of a non-access stratum (NAS) timer based on determining operation in the wideband and the EC restriction. The UE may further transmit an access request message to a network entity to trigger a mobility management procedure. The UE may further receive an acceptance message from the network entity indicating an unrestricted or restricted status of the EC restriction. The UE may further apply the duration to the NAS timer based on the acceptance message indicating the unrestricted or restricted status of the EC restriction received from the network entity or a history of EC restrictions of a public land mobile network (PLMN) in a defined geographic area.

Abstract: A user equipment (UE) may make a joint decision of adaptive receive diversity (ARD) and adaptive transmit diversity (ATD) configurations, including transmit (Tx) and receive (Rx) antennas selection and/or blanking based on downlink (DL) and uplink (UL) traffic conditions. The UE may disable at least one Tx chain for a transmission of a codebook-based sounding reference signal (SRS) (SRS-CB) based on one or more of at least one DL traffic condition or at least one UL traffic condition, and transmit, to a base station, upon disabling the at least one Tx chain, the SRS-CB via an antenna associated with at least one active Tx chain.

Abstract: A method of wireless communication performed at a user equipment (UE), includes transmitting, to a network node, a first indication of a first UE radio capability, the first UE radio capability indicating support for a group of evolved universal terrestrial radio access network (E-UTRAN) new radio (NR) dual connectivity (EN-DC) band combinations. The method also includes receiving, from the network node, an indication of an active EN-DC band combination based on transmitting the first indication. The method further includes transmitting, to the network node, a second indication of a second UE radio capability based on an actual data throughput metric associated with the active EN-DC band combination satisfying a failure condition. The second UE radio capability may indicate support for one or more non-active EN-DC combinations. Each non-active EN-DC combination may be associated with a potential data throughput metric that is greater than a data throughput threshold value.

Abstract: Methods (1500, 1600, 1700, 1800, 1900), systems (1000, 1400) and devices (705, 805, 1005, 1105, 1205, 1405) for wireless communications are presented. A method (1500, 1600) may include the following operations. A UE determines to perform a handover from a first source device in a first network to a first target device in the first network and from a second source device in a second network to a second target device in the second network (1505, 1605). The UE identifies a time interval for performing a first random access procedure with the first target device in the first network (1510, 1610). The UE initiates a first random access procedure with the first target device (1515, 1615). The UE performs a second random access procedure successfully with the second target device in the second network during the time interval (1520, 1620). The UE transmits or receives from the target device in the second network before the UE finishes performing the first random access procedure with the first target device in the first network (1525, 1630).

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.
