  • Patent number: 11838777
    Abstract: An apparatus for a Next Generation Node-B (gNB) includes processing circuitry coupled to memory. To configure the gNB for QoS monitoring in an NG-RAN with a control plane (CP)-user plane (UP) separation, the processing circuitry is to decode assistance information data received at a gNB Central Unit (gNB-CU) node of the gNB from a gNB Distributed Unit (gNB-DU) node of the gNB. The gNB-CU node is hosting an NR PDCP. The gNB-DU node is configured as a corresponding node of the gNB. The assistance information data includes delay information of a communication link of the NG-RAN measured by the corresponding node. A delay associated with the communication link is determined at the gNB-CU node of the gNB, based on the delay information measured by the corresponding node.

  • Patent number: 11818793
    Abstract: Devices, methods, user equipment (UE), base stations, storage media, and other embodiments are provided for managing associations in a communication network. In one example embodiment, a Next Generation (NG) core network device is configured for an Access and Mobility Management Function (AMF) with an NG-Radio Access Network (NG-RAN) node. The network device may be configured to access a plurality of Transport Network Link (TNL) associations and generate an AMF configuration update using the TNL associations, the AMF configuration update comprising AMF transport layer address information for the plurality of TNL associations. The network device may then initiate transmission of the AMF configuration update comprising the AMF transport layer address information to the NG-RAN node. Additional embodiments may involve binding updates or setup response messaging for managing associations, along with additional operations.

  • Publication number: 20230362624
    Abstract: The present application relates to user equipment (UE) aggregation. For instance, a UE aggregation group is defined based on a subscription of multiple UEs with a network. Configuration information identifying the UE aggregation group, its member UEs, the role of each UE (e.g., whether a group leader or, otherwise, a group member), and/or radio access capability signaling (RACS) is stored. Upon a registration of a UE, the UE aggregation group is indicated to the network. The network then enables an aggregated communication capability to the UEs of the UE aggregation group based on the configuration information.

  • Publication number: 20230337119
    Abstract: Techniques are disclosed for the harmonization of a spectrum access tier and a core network architecture. One example includes a method implemented for the harmonization of a spectrum access tier and a core network architecture. An access and mobility management function (AMF) of a first network can receive a first request message, including a spectrum inquiry request from a base station to an automated frequency coordinator of the first network. The automated frequency coordinator can use an AMF interface and an automated frequency coordinator interface to determine a spectrum inquiry response. The spectrum inquiry response can describe an available frequency band of a spectrum access tier of a second network for the base station. The AMF can transmit the spectrum inquiry response to the base station.

  • Patent number: 11729658
    Abstract: Systems and methods of providing feedback when a specific PDU is successfully delivered or transmitted are described. The node hosting PDCP entity indicates triggering of a DDDS frame from the remote corresponding node. Rather than immediately triggering transmission of a DDDS frame, the node hosting PDCP entity indicates triggering based on successful delivery of a PDU having a specific SN, as long as in-sequence delivery or transmission of PDUs up to the specific SN was successful. The DDDS frame is transmitted once the corresponding node determines that the PDU having the SN was successfully delivered or transmitted. After reporting by the DDDS frame, the QoS flow associated with the PDUs is remapped from a source DRB to a target DRB.

  • Patent number: 11723088
    Abstract: Systems and methods of setting up an E1 interface for a gNB are described, A transmitting entity of the gNB-CU-CP and gNB-CU-UP initiates the first TNL association between the gNB-CU-CP and gNB-CU-UP, and is also limited to initiating the E1 Setup procedure. The transmitting entity sends an E1 SETUP REQUEST message to set up the E1 interface. Afterwards, a message is received from the receiving entity. The transmitting entity determines that the setup of the E1 interface is successful if the message contains IEs of an E1 SETUP RESPONSE message. The types of IEs include a message type IE and a name of the transmitting entity.

  • Publication number: 20230189380
    Abstract: Various embodiments herein provide techniques for small data transmission of a user equipment (UE) in a radio resource control (RRC) inactive state. The techniques may be used with a next generation Node B (gNB) that employs a distributed unit (DU)/centralized unit (CU) split. The DU receives, from the UE in the RRC inactive state, data and processing information for processing for the data, processes the data based on a radio link control (RLC) bearer, and sends the processed data to the CU.

  • Patent number: 11622397
    Abstract: An apparatus of a next generation NodeB (gNB) comprises one or more baseband processors to interconnect a gNB Central Unit control-plane entity (gNB-CU-CP) with a gNB Central Unit user-plane entity (gNB-CU-UP) via an E1 control plane interface and a gNB Distributed Unit (gNB-DU) via an F1 control plane interface. Rather than relying on multiple class-1 procedures initiated by gNB-CU-CP toward gNB-CU-UP and gNB-DU, the one or more baseband processors are configured to establish or modify a bearer context and to communicate data transport tunneling and/or packet data convergence protocol (PDCP) preservation status information for a specific user equipment (UE), utilizing the direct F1 user plane interface between gNB-DU and gNB-CU-UP to avoid relaying delay. The gNB can include a memory to store the bearer context and data transport tunneling information.
