    Abstract: Briefly, in accordance with one or more embodiments, an apparatus of a user equipment (UE), comprises one or more baseband processors to derive a dynamic scrambling key, and a memory to store the dynamic scrambling key and a temporary UE identifier (temporary UE ID) assigned to the UE. The one or more baseband processors monitor a paging request for a scrambled UE identifier (UE ID) to determine if the paging request is intended for the UE by unscrambling the scrambled UE ID with the dynamic scrambling key to produce the temporary UE ID. The paging request is intended for the UE if the temporary UE ID produced by unscrambling the scrambled UE ID matches the temporary UE ID stored in the memory. A new dynamic scrambling key may be derived each time the UE returns to a radio resource control idle (RRC_IDLE) state.

    Abstract: A user equipment (UE) can include processing circuitry configured to decode system information including access barring parameters for one or more access categories for accessing a cell of a next generation Node-B (gNB). A network access attempt is detected by a control plane layer of the UE that is higher than a Radio Resource Control (RRC) layer. The processing circuitry map s, using a Non-Access Stratum (NAS) layer of the control plane, the network access attempt to at least one access category of a plurality of available access categories based on mapping rules. The processing circuitry performs an access barring check procedure for the mapped at least one access category based on the access barring parameters. Upon determining that access to the cell is not barred, a NAS message is encoded for transmission to an Access and Mobility Management Function (AMF), e.g. an Attach Request message to perform an attach procedure.

    Abstract: A method performed by a client device is provided. The method includes obtaining, by a client device, data for transmission to a network server. The method includes determining, by the client device, a plurality of intermediate network nodes for transmission of the data, wherein the plurality of the intermediate network nodes are communicatively coupled to the network server. The method includes encoding, by the client device, the data using an encoding scheme. The method includes transmitting, by the client device and according to a data transmission scheme, a plurality of instances of the encoded data to the plurality of intermediate network nodes for aggregation by the intermediate network nodes with data received from one or more other client devices. Also provided are methods performed by an intermediate network node and a network server. The methods can be performed by one or more processors of an apparatus.

    Abstract: A computer system that establishes a first registration and a second registration in a common wireless communication system is described. During operation, the computer system performs a first registration of the user equipment over a first access, where, after the first registration, the user equipment is connected via the first access with a first access and mobility management function (AMF). Then, the computer system performs a second registration of the user equipment over a second access, where the second access is different from the first access and, after the second registration, the user equipment is connected via the second access with a second AMF. Moreover, when performing the second registration, the computer system: transfers a context of the user equipment from the first AMF to the second AMF; and/or relocates a network interface in a control plane from the first AMF to the second AMF.
