Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may perform, while camped on a cell of a first radio access technology (RAT), a search for closed access group (CAG) cells of a second RAT different from the first RAT. The UE may populate a database based at least in part on the search, wherein populating the database includes associating the cell of the first RAT with one or more of the CAG cells of the second RAT. The UE may perform a reselection process from the cell of the first RAT to a first CAG cell of the second RAT, of the one or more CAG cells of 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 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: 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 obtain a band priority list identifying a set of bands in a prioritized order. The UE may perform a system scan of one or more bands of a frequency list that are associated with at least a threshold energy level in the prioritized order of the one or more bands in the band priority list. 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.
