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: Disclosed are systems, apparatuses, methods, and computer-readable media for use in a wireless network for facilitating radio access synchronization. The method includes receiving, from a user equipment (UE) a message having a media access control (MAC) control element (CE) format and comprising a MAC protocol data unit (PDU) structure, the message being formed by multiplexing one or more MAC service data units (SDUs). The method further includes generating a response message to the received message by multiplexing a MAC random access response (RAR) with one or more MAC SDUs. The method then transmits the response message to the UE

Abstract: Some embodiments of this disclosure include systems, apparatuses, methods, and computer-readable media for the reduction of handover interruptions. Some embodiments include a user equipment (UE) that supports simultaneous connectivity with a source 5G Node B (gNB) and a target gNB during a handover. Some embodiments include the UE receiving source path data packets from the source gNB and target path data packets from a target gNB. The UE performs a first reorder of the one or more source path data packets and the one or more target path data packets by sequence number (SN), and the UE performs header decompression on the reordered source path data packets, separately from the reordered target path data packets. After the header decompressions the UE performs a second reorder of the source path data packets and the target path data packets together by SN, and discards any duplicate data packets based on SNs.

Abstract: The present disclosure relates to selecting a Local Management Function (LMF) in a wireless communication network, a next generation Radio Access Network (NG-RAN) acquires a capability from a user equipment (UE), the capability indicating whether the UE is capable of supporting LMF in Radio Access Network (RAN). An access and mobility management function (AMF) is then notified whether the UE is capable of supporting LMF in RAN. An LMF selection is then received from the AMF. Then a response is transmitted to the UE based on the received LMF selection, the response indicating whether a positioning procedure to be carried out by the UE is based on LMF in RAN. In this manner, the capabilities of the UE are taken into consideration when selecting an LMF for a positioning procedure.

Abstract: Techniques for unifying split bearers at user equipment (UE) in an Evolved-Universal Terrestrial Radio Access-New Radio (E-ULTRA NR) dual connectivity (EN-DC) environment are described. According to various such techniques, a radio resource control (RRC) message can include an encapsulated configuration for a secondary cell group (SCG). Packet data convergence protocol (PDCP) configurations for MN or SN split bearers can be included in the master cell group (MCG) configuration in the RRC message or in the encapsulated SCG configuration. In some examples, an RRC message can include an encapsulated SCG configuration and an encapsulated PDCP configuration, where the encapsulated PDCP configuration including PDCP configuration information for the MN or SN split bearer. Other embodiments are described and claimed.

Abstract: Some demonstrative embodiments include devices, systems and/or methods of communication over common control channels. For example, an apparatus may include logic and circuitry configured to cause a User Equipment (UE) to determine a selected Common Control Channel (CCCH) message configuration from a first predefined message configuration and a second predefined message configuration, the first predefined message configuration having a first predefined message bit-size, the second predefined message configuration having a second predefined message bit-size; to generate an Uplink (UL) CCCH message according to the selected CCCH message configuration, the UL CCCH message comprising a Medium Access Control (MAC) header comprising a Logical Channel Identify (ID) (LCID) field having a value corresponding to the selected CCCH message configuration; and to transmit the UL CCCH message to a Next Generation Node B (gNB) over a logical channel corresponding to the selected CCCH message configuration.

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.
