    Abstract: A wireless local area network (WLAN) point-to-point communications link between an evolved universal terrestrial radio access network node B (eNB) and a user equipment device (or simply UE) is identified by UE/eNB media access control (MAC) identifiers on a per UE or per data radio bearer (DRB) basis for offloading cellular data from a long term evolution (LTE) link to the WLAN point-to-point communications link. A wireless local area network tunneling protocol (WLTP) includes packet formats and network protocol stack arrangements to support functions facilitated by the WLAN point-to-point communications link, such as, for example, identification of control and data traffic messages, DRB identification for WLTP packets, quality of service (QoS) delay and packet loss measurement, support of bearer splitting, and support of a general framework for offloading cellular traffic at different depths of the 3rd Generation Partnership Project (3GPP) network protocol stack.

    Abstract: Examples are disclosed for coordinating transmission of one or more protocol data units to a wireless device from a coordinating set of base stations. In some examples, coordinating may include exchanging information via a backhaul communication channel coupling or interconnecting the base stations included in the coordinating set of base stations. For these examples, one or more protocol data units may be transmitted to the wireless device from the coordinating set of base stations via a plurality of separate communication links based on the exchanged information. Other examples are described and claimed.

    Abstract: An apparatus of a Next Generation Node-B (gNB) with a CP-UP separation includes processing circuitry configured to decode a radio resource control (RRC) request message from the UE for establishing a connection between the UE and a UPF of a 5G NR architecture in a network slice. In response to a confirmation message that the UE is authorized to communicate via the network slice, encode a Central Unit User plane (CU-UP) resource status request message for transmission by a Central Unit Control Plane (CU-CP) entity of the gNB to a plurality of CU-UP entities. A CU-UP resource status response message from each of the plurality of CU-UP entities is decoded at the CU-CP entity. The resource status response message including resource availability information for the CU-UP entities. A CU-UP entity is selected by the CU-CP entity from the plurality of CU-UP entities based on the resource availability information.

    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.

    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.

    Abstract: Embodiments described herein relate to managing bearers in a radio access network (e.g., next generation RAN (NG-RAN), etc.). In one example, a central-unit control-plane (CU-CP) communicates with a distributed unit (DU) and a CU-UP to exchange transport network layer addresses (TNLAs) and tunnel endpoint identifiers (TEIDs) between the DU and the CU-UP. In this way, the DU becomes resistant to the CU-UP's rejection of a bearer setup request from the CU-CP during a bearer setup procedure. Furthermore, during virtual machine (VM) migration or local problems of the CU-UP, an E1 procedure known as “bearer relocate” can be defined to notify the DU of a new TNLA for one or more affected general packet radio service tunneling protocol (GTP) tunnels that are affected by the VM migration or local problems.
