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.

Abstract: Some demonstrative embodiments include devices, systems and/or methods of Wireless-Local-Area-Network (WLAN) communication in conjunction with cellular communication. For example, an apparatus may include a wireless communication unit to receive WLAN load information indicating a load of at least one WLAN controlled by at least one access point (AP), and, based on the WLAN load information, to select between connecting to the AP and connecting to a cellular node.

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.

Abstract: Uplink (UL) data splits between LTE and WLAN can be go supported in cellular networks. The split can be UE controlled or network controlled. Both UE and network controlled bearer split architectures can be supported. The reporting of Uplink Buffer Status (BSR) and the subsequent data allocation can depend on what option is supported by the network. For UE controlled UL data splits, the UE determines a traffic split ratio between LTE and WLAN. The split can be based on local link conditions. For network controlled UL data splits, the network (e.g. a Link Aggregation Scheduler at the eNB) is responsible for making bearer split decisions. The decisions can be based on link qualities, available traffic and quality of service (QoS) requirements of associated users. The split can be based on a per bearer threshold, an eNB configured ratio, or an implicit inference based on a UL grant.

Abstract: Embodiments described herein relate generally to techniques for paging in a wireless network. In some embodiments, a mobility management entity (MME) may determine a user equipment (UE) is associated with a predetermined category and adjust paging mechanisms based on said determination. Other embodiments may be described and claimed.

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: Embodiments of a Next Generation Node-B (gNB) and methods of communication are disclosed herein. The gNB may be configured with a gNB central unit (gNB-CU) and a gNB distributed unit (gNB-DU). The gNB-CU may determine a route for delivery of a data packet to a User Equipment (UE) on an integrated access backhaul (IAB) of relays. The gNB may generate a physical layer (PHY) data packet in accordance with a split between functionality of a packet data convergence protocol (PDCP) layer at the gNB-CU and functionality of a radio link control (RLC) layer at the gNB-DU. The PHY data packet may include the data packet, a PDCP header, an adaptation layer header, an RLC header, a medium access control (MAC) header, and a PHY header. The adaptation layer header may indicate one or more relays included in the route.

Abstract: The functions of user equipment (UE), radio access network (RAN) devices, and core network (CN) devices in circumstances where a UE is expected to experience discontinuous coverage are described herein. A UE may send a CN a non-access stratum (NAS) message including a release request indicating that a UE is leaving coverage and assistance information. The CN may interrupt paging of the UE and resume the paging according to the assistance information. A UE may enter a low power usage mode upon leaving coverage, and may use one or more timers to determine when to check for coverage and send a mobility update message corresponding to the low power usage mode. A base station may receive, from a UE, a radio resource control (RRC) message comprising a release request and assistance information, send an RRC release message to the UE in response, and forward the assistance information to the CN.
