Abstract: Embodiments of the present disclosure relate to multi-path operation. According to embodiments of the present disclosure, a measurement report is transmitted to a base station on a first path between the UE and the base station, wherein the measurement report indicates channel quality information on one or more potential paths between the UE and the base station. A path addition command is then received from the base station, wherein the path addition command indicates the UE to add a path from one or more potential paths as a second path. The second path between the UE and the base station is then established based on the path addition command.

Abstract: A master node (MN) that determines a manner of a protocol data unit (PDU) session to be served, wherein the manner of the PDU session includes a split PDU session between the MN and a secondary node (SN) or a whole PDU session served by the MN, generates a request message to be transmitted to the SN to setup PDU session resources on the SN based on the manner of the PDU session is to be served and indicates, to the SN, the manner of the PDU session to be served. A SN that receives, from a MN, a request message to setup PDU session resources, determines a manner of the PDU session to be served, and sets up the PDU session resources on the SN, based on at least the manner of the PDU session to be served.

Abstract: A next generation NodeB (gNB) implements a radio access network (RAN) convergence functionality for new radio (NR) and wireless local area network (WLAN) access, the gNB further implementing a split architecture comprising a central unit (CU) and a distributed unit (DU) for each of the NR access and WLAN access. The gNB receives a data packet for transmission to a user equipment (UE) implementing the RAN convergence functionality, the data packet comprising one of a control plane (CP) packet or a user plane (UP) packet. The gNB splits the data packet via a convergence layer residing on the NR CU or a convergence layer residing on the WLAN CU and transmits the split data packet over the NR access and the WLAN access.

Abstract: Apparatuses, systems, methods, and computer-readable media associated with F1 interface arrangement configuration within a network that implements virtualized NodeBs are disclosed herein. In embodiments, one or more non-transitory computer-readable media having instructions stored thereon, wherein the instructions, in response to execution by one or more processors, cause a centralized unit (CU) of an access node to generate a CU configuration update message, the CU configuration update message to include an indication of a transport network layer (TNL) address of the CU for which a TNL association between the CU and a distributed unit (DU) of the access node is to be added or removed, and cause the CU configuration update message to be transmitted to the DU. Other embodiments may be described and/or claimed.

Abstract: Techniques, systems, and devices to support small data transfers are described. A first node, such as a gNodeB or an eNodeB, can perform operations that include receiving a resume request from a user equipment (UE) that is in an inactive state, the resume request including a small data indication, where context information for the UE resides at a second node; transmitting a retrieve UE context request to the second node, the retrieve UE context request including the small data indication; receiving a UE context response from the second node; transmitting, by the first node, a resume response to the UE to cause the UE to switch to a connected state; processing uplink data from the UE; and transmitting a release message to the UE to cause the UE to switch to the inactive state. The release message can be based on RRC release information received from the second node.
