Abstract: Aspects are provided which allow a UE to apply new radio high-speed train mode determination and false alarm suppression in HST deployments. The UE combines a plurality of indications associated with a high-speed train (HST) mode detection into a consolidated HST mode configuration signal. The UE determines whether to suppress the consolidated HST mode configuration signal based on a mobility metric of the UE and a plurality of thresholds. The UE transitions into a HST mode when the consolidated HST mode configuration signal is not suppressed based on the mobility metric of the UE exceeding at least one of the plurality of thresholds. As a result, false HST mode flags may be avoided and HST mode detection success rates may thereby be improved.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network entity, an absolute threshold synchronization signal block (SSB) consolidation parameter. The TUE may determine whether a threshold value indicated in the absolute threshold SSB consolidation parameter satisfies a predefined value threshold. The UE may set a specific network deployment flag based at least in part on whether the threshold value satisfies the predefined value threshold. The UE may determine a cell measurement result based at least in part on the specific network deployment flag. The UE may perform a downlink beam selection and a beam switch evaluation based at least in part on the specific network deployment flag. 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, from a high speed train (HST) cell, a system information block (SIB) indicating an HST flag based at least in part on the UE camping on the HST cell. The UE may disconnect from the HST cell and camping on a non-HST cell based at least in part on a UE mobility in an HST railway. The UE may determine that disconnecting from the non-HST cell and camping on a new HST cell is to be prioritized over remaining on the non-HST cell, based at least in part on the UE being in the HST railway and based at least in part on a priority of HST cells being greater than a priority of non-HST cells. 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 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: 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: The UE may store target cell information to a database based on performing a handover to the target cell and detecting the ping-pong handover based on a number of handover instances in the database of the target cell to which the UE has performed the handover being greater than or equal to a threshold number of the handover instances within a period of time. The UE may receive, from a base station a list of ping-pong cell candidates and configure the number of handover instances of the target cell and/or the period of time based on the list of ping-pong cell candidates. The UE may avoid or reduce the handover to the identified ping-pong cell based on the detected ping-pong handover by applying an offset to the measurement of the target cell.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from an application processor associated with the UE, an indication of a traffic service type and whether an uplink data stall has occurred. The UE may detect that one or more threshold criteria are satisfied for a serving cell, wherein a threshold value associated with at least one of the one or more threshold criteria is based at least in part on the traffic service type. The UE may transmit information associated with one or more adjusted measurement values of the serving cell based at least in part on detecting that the one or more threshold criteria are satisfied. Numerous other aspects are described.
