Abstract: A method for of wireless communication, by a multi-subscription user equipment (UE) includes selecting a first subscription to receive a positioning system information broadcast (posSIB) based on a first subscription state and a second subscription state. The method also includes receiving the posSIB via the first subscription. The UE may switch from the first subscription to a second subscription to receive a subsequent posSIB, in response to the second subscription state changing and/or the first subscription state changing. The state switching may be between connected mode and inactive/idle mode, or between voice service and data service.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a multi-subscriber identity module (SIM) user equipment (UE) may communicate, using a first SIM, on a plurality of component carriers. The multi-SIM UE may select a first subset of component carriers from the plurality of component carriers based at least in part on a component carrier prioritization. The multi-SIM UE may identify an amount of memory available to a second SIM. The multi-SIM UE may tune away, based at least in part on the amount of memory available to the second SIM, from a second subset of component carriers The first subset of component carriers may be different from the second subset of component carriers. Numerous other aspects are described.

Abstract: Aspects of the present disclosure provide techniques to enable enhanced machine type communication (s) (eMTC) and/or narrowband Internet-of-Things (NB-IoT) devices to transition to idle mode after releasing a connection, such as a radio resource control (RRC) connection, more quickly than with previously known techniques. An example method includes determining, based on an indication received in a narrowband signal on a narrowband region of a bandwidth comprising a plurality of narrowband regions, whether to wait for a delay period, determined based on a configuration received from a network entity, before releasing a radio resource control (RRC) connection and releasing the RRC connection at a time in accordance with the determination.

Abstract: Aspects related to performing power control over a secondary carrier are described. At least one parameter can be received for performing power control over a carrier with a cell. Based on the at least one parameter, at least one alternative parameter can be determined for performing a power control procedure for a secondary carrier with the cell, and the power control procedure for the secondary carrier with the cell can be performed based at least in part on the at least one alternative parameter. The at least one alternative parameter may result in a power control procedure for the secondary carrier that takes less time than a power control procedure for the primary carrier with the cell.

Abstract: The present disclosure presents a method and an apparatus for managing radio resource control (RRC) state transitions at a user equipment (UE). For example, the method may include transmitting a reconfiguration complete message to a network entity, starting a reselection delay timer simultaneously with the transmitting of the reconfiguration complete message, identifying initiation of a cell reselection procedure at the UE, delaying the cell reselection procedure at the UE until the UE receives a layer 2 acknowledgement (L2 ACK) message from the network entity, stopping the reselection delay timer in response to receiving the L2 ACK message, and transitioning the UE to a cell_paging channel (cell_PCH) state from a cell_forward access channel (cell_FACH) state after the stopping of the reselection delay timer. As such, managing RRC state transitions at a UE may be achieved.

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: 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 UE may include IoT NTN device, and the UE may acquire the GNSS location to perform the time/frequency pre-compensation. A NAS layer of the UE may initiate a connection request procedure based on the GNSS fix procedure at one or more lower layer of the UE. A network may transmit a paging request to the UE, and manage a paging response timer based on the GNSS fix procedure at the UE.

Abstract: Aspects of the present disclosure provide techniques and apparatus for wireless communication. In one aspect, a method is provided which may be performed by a wireless device such as a user equipment (UE). The method generally includes determining a scheduled occurrence of a measurement gap, wherein the UE measures neighbor cell signal strength during the measurement gap, and adjusting the measurement gap based on at least one criterion.
