  • Long-term evolution (LTE) and wireless local area network (WLAN) aggregation (LWA) connection procedures
    Patent number: 11140691
    Abstract: Technology for a user equipment (UE) to perform long-term evolution (LTE) and Wireless local area network (WLAN) aggregation (LWA) connection procedures within a wireless communication network is disclosed. The UE can determine to suspend communication on a wireless local area network (WLAN) of one or more protocol data units (PDUs) for a LWA session without terminating the LWA session. The UE can process, for transmission to an eNodeB, a request to suspend communication of the one or more PDUs on the WLAN to enable the eNodeB to schedule the one or more PDUs for transmission to the UE through a cellular interface without terminating the LWA session.

  • SYSTEMS, METHODS AND DEVICES FOR UPLINK BEARER AND ACCESS CATEGORY MAPPING
    Publication number: 20210266915
    Abstract: Mapping information of a bearer or quality of service can be communicated from a Wireless Local Area Network Termination (WT) to the enhanced Node B (eNB), which then uses radio resource control (RRC) signaling to communicate the mapping to the user equipment (UE). For example, three options can be used to communicate mapping information: (1) Operations and Management (OAM), (2) Semi-static Xw-AP signaling (e.g., WT Configuration Update or Xw Setup procedures) or (3) Dynamic Xw-AP procedures (e.g., WT Addition Request procedure). In some embodiments, the mapping can be signaled by (1) bearer to wireless local area networks (WLAN) access category (AC) mapping or (2) long term evolution (LTE) quality of service class identifier (QCI) to WLAN AC mapping.

  • PDCP Packet-Based DDDS Frame Transmission
    Publication number: 20210266779
    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.

  • APPARATUS AND METHOD FOR CONGESTION HANDLING IN RADIO ACCESS NETWORK
    Publication number: 20210211928
    Abstract: Provided herein is an apparatus and a method for congestion handling in RAN. The disclosure provides an apparatus for a relay node in a RAN including the relay node and a donor node providing an interface to a core network and a backhaul link to the relay node. The apparatus includes a RF interface to receive and transmit downlink data for one or more UEs or UE bearers; and a processing circuitry coupled with the RF interface. The processing circuitry is to determine a downlink congestion occurs at the relay node; and generate a downlink congestion indication to identify a UE or a UE bearer or a backhaul RLC channel affected by the downlink congestion. The RF interface is to transmit the downlink congestion indication to the donor node. In addition to the downlink congestion handling, the relay node can also be to handle uplink congestion in a similar way.

  • Enhancing User Plane Contexts Management in New Radio (NR)
    Publication number: 20210176802
    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.

  • Next Generation Node-B (GNB) and Methods for Mobility Management with Separate User Plane and Control Plane in New Radio (NR) Systems
    Publication number: 20210176676
    Abstract: Embodiments of a Next Generation Node-B (gNB) and methods of communication are disclosed herein. The gNB may be configurable to operate as a source gNB (S-gNB). The S-gNB may transfer, from a control plane (CU-CP) of the S-gNB to a CU-CP of a target gNB (T-gNB), an XnAP handover request message that indicates an Xn handover of a User Equipment (UE) from the S-gNB to the T-gNB. The S-gNB may initiate data forwarding, from a user plane (CU-UP) of the S-gNB to a CU-UP of the T-gNB, of downlink data packets. The data forwarding may be terminated based on reception of end marker packets from a user plane function (UPF) entity. The CU-UP of the S-gNB may transfer end marker packets to the CU-UP of the S-gNB to indicate termination of the data forwarding.

    Publication number: 20210168637
    Abstract: An apparatus for use in a base station includes processing circuitry coupled to a memory. To configure the base station for 5G-NR QoS monitoring and reporting in a 5G-NR network, the processing circuitry is to decode a UE component of a UL delay measurement associated with a Uu interface. The UE component of the UL delay measurement is received at a CU-UP from a CU-CP of the base station. A DU component and a CU-UP component of the DL and UL delay measurements associated with the DU of the base station are determined. A DL or UL delay result between the NG-RAN and the UE is encoded for transmission to a UPF of the 5G-NR network.

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.

  • Flexible flow control mechanism for NG-RAN interfaces
    Patent number: 10966284
    Abstract: An apparatus of a RAN node in which flexible feedback for user data transferred between RAN nodes is described. The DL PDCP PDUs to be delivered to a UE is transmitted over an Xn or X2 interface between RAN and NG-RAN nodes, respectively. Feedback received allows transmitting RAN node to control downlink user data flow. The feedback contains a DDDS frame that includes a highest transmitted and delivered PDCP SN indicator parameter that respectively indicates whether a highest transmitted and successfully delivered PDCP PDU is present in the DDDS message and a highest transmitted and successfully delivered PDCP SN PDU parameter that provides feedback respectively about a transmitted status of the PDU sequence and an in-sequence delivery status of the PDUs to the UE. Buffered PDUs reported by the DDDS message are removed from memory as transmitted or successfully delivered PDUs.
