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.

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: Systems and methods of modifying the bearer context of a DRB of an E1 interface for a gNB are described. To modify the bearer context associated with a DRB for a particular UE, the gNB-CU-UP transmits a Bearer Context Modification Required message through the E1 interface and receives in response a Bearer Context Modification Confirm message that confirms the modification of the bearer context. The Bearer Context Modification Required message and Bearer Context Modification Confirm message both include the new GTP TEID and TNL address to be used after modification of the bearer context, a gNB-CU-CP UE E1AP ID that uniquely identifies a UE association over the E1 interface within the gNB-CU-CP, a gNB-CU-UP UE E1AP ID that uniquely identifies a UE association over the E1 interface within the gNB-CU-UP, and a DRB ID IE that uniquely identifies the DRB.

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) are described herein. The gNB may be configured with logical nodes, including a gNB central unit (gNB-CU) and a gNB distributed unit (gNB-DU). The gNB-CU may comprise a gNB-CU control plane (gNB-CU-CP) for control-plane functionality, and a gNB-CU user plane (gNB-CU-UP) for user-plane functionality. The gNB may initiate an E1 interface setup procedure, a bearer context setup procedure, and a UE context setup procedure to establish a UE context that includes a signaling radio bearer (SRB) and a data radio bearer (DRB) configuration. The UE context setup request message may be configured to include quality-of-service parameters for the DRB configuration.

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.
