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.

Abstract: Techniques, described herein, include solutions for managing hybrid automatic repeat request (HARQ) processes and communications for non-terrestrial networks (NTNs) (e.g., a wireless communication network that includes a satellite network component). A user equipment (UE) may connect to an NTN and determine hybrid automatic repeat request (HARQ) capabilities regarding NTNs. The UE may also communicate a HARQ disablement message to the NTN and communicate with NTN without HARQ procedures. The HARQ disablement message may provide the HARQ disablement capabilities of the UE and/or be a request for the network to disable HARQ. The HARQ disablement message may include a radio resource control (RRC) reconfiguration message and may address HARQ disablement per logical channel identifier (LCID) or dedicated radio bearer (DRB).

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 include 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: 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.
