    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: 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.

    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.
