Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a first signal associated with a first radio access technology (RAT) and a second signal associated with a second RAT. The UE may determine that first signal measurements associated with the first signal satisfy a first condition and second signal measurements associated with the second signal satisfy a second condition. The UE may transmit, to a first base station associated with the first RAT, a measurement report that excludes the first signal measurements and the second signal measurements based at least in part on the first condition and the second condition being satisfied. 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 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: Got Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may switch between a first radio access technology (RAT) and a second RAT based at least in part on a condition. The UE may modify, based at least in part on the switching, a second RAT threshold value in a system information block (SIB), to obtain a modified second RAT threshold value, wherein the modified second RAT threshold value is a value to switch from the first RAT to the second RAT. 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: 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.
