  • Patent number: 11457503
    Abstract: A centralized RAN architecture that includes lower layer transmission nodes (referred to as distributed units (DUs) herein) that connect to an upper layer RAN node (referred to as a centralized unit (CU) herein). A centralized RAN architecture may include a functional split, between the CU and DU, corresponding to the Packet Data Convergence Protocol (PDCP) and Radio Link Control (RLC) layers. In one embodiment, a CU may store copies of downlink PDCP PDUs that are transmitted to a first DU. The CU may retransmit, to a second DU, those of the PDCP PDUs which were previously transmitted to the source DU but have not been acknowledged as successfully delivered by the source DU.

  • Patent number: 11445564
    Abstract: Techniques described herein may be used to enable User Equipment (UE) to switch between Radio Access Technologies (RATs) while transitioning from an inactive state to an active state. For example. a UE may connect to a base station via one type of RAT (e.g., Long-Term Evolution (LTE) RAT), enter an inactive state, and later, while transitioning from the inactive state to an active state, connect to another base station via another type of RAT (e.g., a New Radio (NR) or 5th Generation (5G) RAT). The UE may transition from one RAT to another RAT without increasing signaling between the UE and the network beyond minimal signaling involved in a transition of the UE from the inactive state to an active state. The network may further minimize signaling by determining and communicating minimized connection configuration information to the UE.

  • Publication number: 20220256436
    Abstract: Some embodiments of this disclosure include systems, apparatuses, methods, and computer-readable media for the reduction of handover interruptions. Some embodiments include a user equipment (UE) that supports simultaneous connectivity with a source 5G Node B (gNB) and a target gNB during a handover. Some embodiments include the UE receiving source path data packets from the source gNB and target path data packets from a target gNB. The UE performs a first reorder of the one or more source path data packets and the one or more target path data packets by sequence number (SN), and the UE performs header decompression on the reordered source path data packets, separately from the reordered target path data packets. After the header decompressions the UE performs a second reorder of the source path data packets and the target path data packets together by SN, and discards any duplicate data packets based on SNs.

    Abstract: In an example method, a user equipment (UE) determines a first identifier assigned to the UE for use on a first wireless communications network and one or more first time slots for monitoring the first wireless communication networks. The UE determines a second identifier assigned to the UE for use on a second wireless communications network and one or more second time slots for monitoring the second wireless communication networks. The UE determines that the one or more first time slots at least partially overlap the one or more second time slots, and in response, transmits to the second wireless communications network, a request for a third identifier to be assigned to the UE for use on the second wireless communications network and/or a request that the one or more second time slots be offset by an interval of time.

  • Publication number: 20220159763
    Abstract: A master node (MN) that determines a manner of a protocol data unit (PDU) session to be served, wherein the manner of the PDU session includes a split PDU session between the MN and a secondary node (SN) or a whole PDU session served by the MN, generates a request message to be transmitted to the SN to setup PDU session resources on the SN based on the manner of the PDU session is to be served and indicates, to the SN, the manner of the PDU session to be served. A SN that receives, from a MN, a request message to setup PDU session resources, determines a manner of the PDU session to be served, and sets up the PDU session resources on the SN, based on at least the manner of the PDU session to be served.

  • Publication number: 20220030488
    Abstract: Apparatuses, systems, and methods for a network node to inter-connect with a first secondary node (SN) within a core network. The network node may be a master node and may serve a UE. The first SN may be a source SN. The network node may initiate a change from the first SN to a second SN, which may be a target SN. The network mode may determine data forwarding from the first SN to the second SN and may request, from the first SN, data forwarding intentions prior to initiating the change from the first SN to a second first SN to the second SN. The network node may send, to the first SN, data forwarding instructions (e.g., based, at least in part, on the data forwarding intentions of the first SN) and the data forwarding instructions may include a requirement for the first SN to follow the data forwarding instructions.
