Abstract: A UE may obtain one or more measurements of at least one cell of a network based on a first connection with the network. The UE may reuse at least a first measurement of the one or more measurements for a second connection with the network. The first connection with the network and the second connection with the network may be associated with different subscriptions or different RATs. To reuse at least the first measurement of the one or more measurements for the second connection with the network, the UE may skip a cell detection operation associated with the second connection with the network.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may compare an external list of ping pong handovers or redirections that is maintained by an access point, and an internal list of ping pong handovers or redirections that is maintained by the UE. The UE may identify a ping pong detection criterion, for a handover or redirection between a first network node and a second network node, based, at least in part, on the external list, the internal list, both the external list and the internal list, or neither of the external list nor the internal list indicating a previous ping pong handover or redirection between the first network node and the second network node. Numerous other aspects are described.

Abstract: Aspects of the present disclosure provide a method for wireless communications by a user equipment (UE). The method generally includes receiving a measurement configuration, wherein the measurement configuration indicates at least one or more frequency bands, determining, based on one or more parameters, a periodicity for measuring the at least one or more frequency bands, and performing measurements of the at least one or more frequency bands according to the determined periodicity.

Abstract: Methods, systems, and devices for wireless communication are described. In some systems, a user equipment (UE) may divide a measurement of a cell into two or more portions. The UE may receive a control message that indicates a request to perform the measurement and a target frequency associated with the measurement. In some examples, the UE may generate at least a first radio frequency (RF) script during an on duration of a discontinuous reception (DRX) cycle based on the target frequency. The UE may perform at least a portion of the measurement during an off duration of the DRX cycle based on the first RF script. Additionally or alternatively, the UE may generate the first RF script and perform the portion of the measurement during an off duration of a DRX cycle and the UE may generate a second RF script during an off duration of a second DRX cycle.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may disconnect from a first radio access technology (RAT) service, independent of signaling from the first RAT service, after sensing that the UE has entered a coverage hole. The UE may use a connection to a second RAT service while in the coverage hole in association with disconnecting from the first RAT service. The UE may disconnect from the second RAT service, independent of signaling from the second RAT service, after sensing that the UE has exited the coverage hole and before expiration of a radio link failure (RLF) timer for the second RAT service. The UE may reconnect to the first RAT service before expiration of an RLF timer for the first RAT service. Numerous other aspects are described.

Abstract: Apparatus, methods, and computer-readable media for enhanced inter-frequency detection between misaligned base stations are disclosed herein. A user equipment (UE) may determine that a neighbor cell associated with a first frequency is misaligned with a serving cell associated with a second frequency different than the first frequency based on first measurements of the neighbor cell within a first measurement gap window having a first length. The UE may detect a location of a synchronization signal block (SSB) associated with the neighbor cell within a second measurement gap window having a second length greater than the first length. The UE may determine an alignment offset between the location of the SSB and the first measurement gap window. The UE may obtain second measurements of the neighbor cell within a third measurement gap window that includes the location of the SSB based on the alignment offset and parameters of the SSB.

Abstract: In a dual network link scenario, a wireless network may provide a user equipment (UE) with a measurement configuration indicating multiple inter-frequency measurement objects during an off duration of a discontinuous reception (DRX) cycle configured on a first network link. The UE may assign the inter-frequency measurement objects to a second network link if the second network link has an always-on configuration. Alternatively, if the second network link has a DRX configuration, the UE may perform some inter-frequency measurement activities on the first network link and assign some inter-frequency measurement objects to unoccupied gap occasions in the off duration for the DRX cycle configured on the second network link. In this way, the UE may save power by spending more time in a low power state, and mobility performance for the UE may be improved by increasing the efficiency and reliability of inter-frequency measurement activities.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with a base station according to a first radio access technology (RAT) in a first frequency range. The UE may perform measurements on a set of candidate cells of a second RAT or a second frequency range based on a determination for the UE to operate according to the second RAT or the second frequency range. The UE may perform a mobility procedure to establish a connection with a first cell of the set of candidate cells based on a determination that a first value of a first measurement parameter for the first cell satisfies a first threshold, and further based on a comparison of a different, second value of a second measurement parameter for the first cell to a second threshold.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station associated with a first radio access technology (RAT), a neighbor cell list including entries for at least a first set of neighbor cells and a second set of neighbor cells, the first set of neighbor cells and the second set of neighbor cells associated with a second RAT. The UE may determine that the first set of neighbor cells is associated with a first network operator and that the second set of neighbor cells is associated with a second network operator. The UE may measure at least one neighbor cell of the neighbor cell list based at least in part on prioritization of the first set of neighbor cells relative to the second set of neighbor cells. Numerous other aspects are described.

Abstract: A user equipment (UE) receives a SIB1 message from a base station. The SIB1 message lists first and second public land mobile network identifiers (PLMN IDs), the first PLMN ID having a corresponding tracking area code (TAC) and the second PLMN ID not having a TAC. The UE reports the first PLMN ID and TAC but not the second PLMN ID while performing PLMN selection. In another aspect, the UE unsuccessfully attempts to select or reselect to a shared cell of the base station with the second PLMN ID. In response to the failed attempt, the UE bars the shared cell as a candidate for cell selection/reselection, due to a missing TAC. When the UE attempts to select or reselect to the shared cell with the first PLMN ID, which may or may not have a TAC, the UE reevaluates the barring due to selection of the first PLMN ID.
