User circuitry within a wireless User Equipment (“UE”) in need of a network slice or a handoff between cells identifies a slice service type. The user circuitry processes an uplink interference threshold of a target cell based on the slice service type. The user circuitry identifies a preferred operating frequency band based on the slice service type and the uplink interference threshold of the target cell. The user circuitry transfers a service request for a wireless data service having the slice service type over the preferred operating frequency band to network circuitry. The network circuitry wirelessly exchanges data with a wireless access node associated with the target cell over the preferred operating frequency band to establish a packet data unit session comprising the slice service type.

Methods, systems, and devices for wireless communication are described. In one example, an aerial user equipment (UE) may receive an indication of a priority for cell selection for aerial UEs from each cell in a set of cells and may select a cell from the set of cells based on the priority of each cell in the set of cells. In another example, an aerial UE may connect to a network available to aerial UEs and non-aerial UEs for auxiliary communications, when appropriate. In yet another example, when an aerial UE transitions to a new mission status, the aerial UE may transmit a tracking area update (TAU) if the aerial UE is connected to a cell in a tracking area that does not support the new mission status. In yet another example, a base station may page an aerial UE based on a mission status of the aerial UE.

Provided in the present disclosure are a spectrum management device and method, a geographic location database, a coexistence discovery device, and subsystems for use in a radio communication system comprising a main system and subsystems. The spectrum management device comprises: a processing circuit, which is configured to: acquire spectrum usage information and spectrum transition capability information of subsystems managed by the spectrum management device, the spectrum usage information corresponding to information related to used spectrums assigned to and used by each subsystem, the spectrum transition capability information corresponding to information related to whether the subsystems support a spectrum transition operation, and an transition of the spectrums of the subsystems managed by the spectrum management device is determined on the basis of the spectrum usage information and the spectrum transition capability information, thus the interference caused by the subsystems as a result of spectrum usage to the main system is limited within a permissible range of the main system. The spectrum management device and method, the geographic location database, the coexistence discovery device, and the subsystems of the present disclosure achieve highly efficient use of spectrum resources.

The present disclosure provides an access control method performed at user equipment (UE), comprising: receiving, from a base station, multiple pieces of access control information corresponding to multiple network types; using the received multiple pieces of access control information to respectively perform an access control check for the multiple network types of networks; starting an access barring timer according to an access control check result; and if the access barring timer times out, informing an upper layer of the UE that barring of access is removed. The present disclosure also provides an access control configuration method for UE performed at a base station, corresponding UE, and a corresponding base station.

Some methods enable a computer to receive location information from a device and determine a coverage region for the device. The device's coverage region is the area within range of a wireless signal coming from the device. The computer can determine that part of the device's coverage region covers part of a specified region and instruct the device to provide wireless access to a network associated with the first region.
