Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE), such as a dual-subscription UE, support a first subscription and a second subscription. The first subscription may be in an active mode with a first cell and the second subscription may be in an idle mode with a second cell, and the UE may determine whether to exit or postpone entrance into a merged state in which the UE may perform idle mode measurements for the second subscription using the first subscription and the first cell based on a channel quality-based merge condition. For example, the UE may measure a channel quality associated with a communication link between the UE and the first cell and, in examples in which the measured channel quality fails to satisfy a threshold channel quality, the UE may exit or postpone entrance into the merged state.

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 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: 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: Methods and mechanisms for performing idle mode mobility procedures are provided. According to one aspect of the present disclosure, a method for wireless communication performed by a user equipment (UE) includes: receiving, from a base station (BS) on a first cell, system information indicating a first cell reselection priority configuration; receiving, from the BS, dedicated signaling indicating a dedicated cell reselection priority configuration, wherein the dedicated cell reselection priority configuration is empty; and connecting, while in an idle mode and in response to the dedicated cell reselection priority configuration being empty, to a second cell different from the first cell based on the first cell reselection priority configuration received in the system information.

Abstract: Methods, systems, and devices for are described. A user equipment (UE) may be configured to initiate a first setup procedure with a first cell supported by a base station. The UE may determine a system information block (SIB) read failure, a radio link failure, or both, based on initiating the first setup procedure. The UE may determine whether a link quality metric associated with communications between the UE and the first cell satisfies a link quality threshold. The UE may select a cell bar time based on a type of a communications service established via the base station, whether the link quality metric satisfies the link quality threshold, or both. The UE may then initiate a cell reselection procedure based on the cell bar time.
