Abstract: An approach is described for a method for a radio access node (RAN) node in a fifth generation (5G) wireless communication or a new radio (NR) system that includes the following steps. The method includes generating a request for location information of a user equipment (UE). The method further includes transmitting the request to an access and mobility function (AMF). The method further includes receiving a response from the AMF, wherein the response comprises the location information of the UE.

Abstract: Some embodiments of this disclosure include systems, apparatuses, methods, and computer-readable media for use in a wireless network for operating eMTC (enhanced Machine Type Communication) user equipment (UE) and/or NB-IoT UEs when connected to a 5G Core Network (5GCN). For example, some embodiments are directed to a user equipment (UE). The UE includes processor circuitry and radio front circuitry. The processor circuitry can be configured to receive, using the radio front end circuitry and from a Non-Access Stratum layer (NAS) of a cell, an indication to use a 5G Core Network (5GCN) for the cell. The processor circuitry can be further configured to transmit, using the radio front end, a Radio Resource Control (RRC) connection request in response to the indication to use the 5GCN.

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 to configure a user equipment (UE) for a multi-connectivity handover with a source base station (SBS) and a target base station (TBS) include encoding a measurement report for transmission to the SBS. The measurement report is triggered based on a measurement event configured by the SBS. Radio resource control (RRC) signaling from the SBS is decoded, the RRC signaling including a handover command in response to the measurement report. The handover command includes an indication for multi-connectivity support by the SBS and the TBS during the handover. A first protocol stack associated with the SBS and a second protocol stack associated with the TBS are configured at the UE. A packet data convergence protocol (PDCP) protocol data unit (PDU) received at the UE during the handover is processed using the first protocol stack or the second protocol stack.

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.

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: One or more methods of using simultaneous connectivity and conditional handover together. At least one of the methods includes transmitting, by a target base station, a reserved resource release command to a source; transmitting, by the source, a new handover (HO) command to update a list of conditional HO (CHO) candidate cells; and releasing, by the target base station, a reserved resource for the UE.
