Abstract: Techniques for recovering quickly from a radio link failure (RLF) by identifying potentially strong candidate cells, while avoiding the conventional delays from relying only on initial ACQ DB scans followed by band-scanning, are disclosed. In one aspect, a wireless apparatus such as a user equipment (UE) may identify a radio link failure (RLF) of an existing wireless connection. The UE may prioritize, during an RLF recovery procedure for restoring the connection, candidate cells using connection criteria from one or more measurement reports. The UE can thereupon restore the connection using a cell having a highest priority. In various configurations, the UE can use cells from A3, A4, A5, inter-RAT or periodic measurement reports to reestablish a stronger connection in a faster time.

Abstract: In a device (120) with two SIMs (305a, 305b), the overlapping DRXs of the two connections is reduced by handovering one of the two SIM to a neighbor cell that satisfies a quality threshold.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless device, such as an in-vehicle device, may determine a selection value for a cell that indicates a priority for selection of the cell by the wireless device and calculates, from the selection value, an adjusted selection value for the cell using an offset that increases a priority of selection for cells that support in-vehicle emergency calls. The wireless device selectively selects the cell based at least in part on the adjusted selection value. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information identifying a set of cells configured for conditional handover (CHO). The UE may identify one or more features associated with a cell. The UE may monitor one or more cells of the set of cells, wherein the one or more cells are associated with the one or more features, and wherein the one or more cells are prioritized over cells not associated with the one or more features in the cell search. The UE may initiate a handover to an identified cell based at least in part on the cell search. 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 handover information associated with one or more neighbor cells. The UE may identify that a first discontinuous reception (DRX) cycle associated with a first subscriber identity module (SIM) of the UE at least partially overlaps with a second DRX cycle associated with a second SIM of the UE. The UE may identify that at least one of the first DRX cycle or the second DRX cycle does not overlap with a third DRX cycle associated with a neighbor cell of the one or more neighbor cells. The UE may transmit, to the neighbor cell, a message associated with a handover of at least one of the first SIM or the second SIM to the neighbor cell. 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 identify a multi-radio access technology (multi-RAT) dual connectivity (DC) (MR-DC) capable cell. The UE may assign a priority to the MR-DC capable cell based at least in part on whether information indicating whether dual connectivity is supported for the UE in a tracking area (TA) is available, the information indicating whether dual connectivity is supported for the UE in the TA, whether system information block (SIB) information indicating frequency bands supported by a network for MR-DC operation cell is available, or MR-DC connectivity information indicating whether at least one frequency band is available to support MR-DC operation. The UE may perform a cell selection procedure or a cell reselection procedure based at least in part on the priority assigned to the MR-DC capable cell. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communication are described that provide for cell selection or reselection at a user equipment (UE) based on cell selection preference criteria of the UE. The UE may receive a set of cell selection criteria that provides a priority order for cell selection based on one or more cell features, cell types, or combinations thereof. The UE, based on one or more signal measurements of available cells and the cell selection criteria, may select one of the available cells for communications. The UE may also maintain a feature cell database in which a number of cells and an associated feature mask may be stored and used to identify cells having features or types associated with the cell selection criteria for use in cell prioritization. Cell selection criteria may be used for cell selection/reselection procedures, mobility procedures, or any combinations thereof.

Abstract: Aspects relate to techniques for expediting New Radio (NR) cell addition in non-standalone (NSA) mode. The UE may receive a conditional handover (CHO) command from a first anchor cell operating a first frequency range (e.g., a Long Term Evolution (LTE) frequency range) that enables the UE to subsequently select a different anchor cell to which to perform a handover. The UE may then receive a deconfiguration from the first anchor cell of a measurement object for secondary cell addition in a second frequency range (e.g., a NR frequency range). Based on the CHO command and the deconfiguration of the measurement object, the UE may then perform a handover to a second anchor cell in the first frequency range to facilitate addition of at least one secondary cell in the second frequency range.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that a first subscription of the UE and a second subscription of the UE are associated with a same cell and are being used for a same radio access technology (RAT). The UE may activate a proxy subscription mode for the first subscription based at least in part on the determination that the first subscription of the UE and the second subscription of the UE are associated with the same cell and are being used for the same RAT, wherein the proxy subscription mode enables the UE to use the first subscription to perform one or more idle mode operations for the second subscription while the second subscription is in an idle mode. Numerous other aspects are provided.
