  • Publication number: 20220038898
    Abstract: An apparatus of user equipment (UE) comprises one or more baseband processors to process at least one non-public network (NPN) identifier (NPN-ID) broadcast by an NPN and zero or more Public Land Mobile Network (PLMN) identifier (PLMN-ID) broadcast by a PLMN, to compare the NPN-ID against a logical list of NPN-IDs and PLMN-IDs ranked in decreasing order of priority, and to connect with the highest ranked processed NPN or PLMN based on a rank of the NPN-ID in the list. The apparatus can include a memory to store the list of NPN-IDs and PLMN-IDs as a logical list of Equivalent Home Networks or as Operator Controlled Network Selector with Access Technology list.

  • Patent number: 11190989
    Abstract: A Next Generation Node-B (gNB) and methods of communication are generally described herein. The gNB is configurable to operate as a source gNB. The gNB is configured with logical nodes including a gNB central unit (gNB-CU) and a gNB distributed unit (gNB-DU). The gNB-CU comprises a gNB-CU control plane (gNB-CU-CP) for control-plane functionality, and a gNB-CU user plane (gNB-CU-UP) for user-plane functionality. When a handover of a User Equipment (UE) from the source gNB to a target gNB is performed, the gNB transfers, from the gNB-DU to the gNB-CU-UP, a downlink data delivery status (DDDS) message to indicate that the gNB-CU-UP is to stop transfer, to the gNB-DU, of downlink data intended for the UE.

    Abstract: Embodiments of a Next Generation Node-B (gNB) and methods of communication are generally described herein. The gNB may be configurable to operate as a source gNB.

  • Publication number: 20190149986
    Abstract: Embodiments of a User Equipment (UE), Next Generation Node-B (gNB) and methods of communication are generally described herein. The UE may randomly select a private key of the UE. The UE may receive, from the gNB, control signaling that includes a public key of the gNB. The UE may generate a shuffling key based at least partly on a public function of the private key of the UE and the public key of the gNB. The UE may determine a random sequence of bits based on a random number generation operation with the shuffling key as a seed. The UE may determine, based on the random sequence of bits, a shuffling array for shuffling of coded bits. The UE may generate the coded bits, and may shuffle the coded bits in accordance with the shuffling array.
