Abstract: Aspects of the disclosure relate to mechanisms for interworking between legacy and next generation radio access technologies (RATs) in a communication network. In some examples, a handover from a legacy access network to a next generation access network may be performed via a next generation core network. A handover request received at a next generation core network serving node may include an identifier of a next generation target cell. The next generation core network serving node may identify another next generation core network serving node to which the handover may be forwarded based on the target cell identifier or may select the next generation access network based on the target cell identifier. The next generation core network serving node may then communicate with the next generation access network to complete the handover.

Abstract: Aspects of the disclosure relate to mechanisms for interworking between legacy and next generation core networks in a communication network. In some examples, a connectivity request originated by a user equipment towards a legacy core network may be transferred to a next generation core network when the user equipment supports the radio access technology of the next generation core network.

Abstract: Methods, systems, and devices are described for improving resource management in wireless communications. More particularly, the methods systems and devices relate to techniques for suspending bearers when not required, for example, for D2D communications. In one example, a mobile device may send a connection request that indicates a service type. The connection request may be a service request (SR) or an extended service request (ESR). A set of bearers may be established for the intended communication(s). The indicated service type may not require all bearers of the set of bearers such that at least one bearer may be suspended.

Abstract: Methods, systems, and devices are described for device-to-device (D2D) wireless communication. A device may transmit an initiation message to a base station indicating that the device desires to initiate a D2D communication session. The device may then receive a response from the base station that includes parameters for configuration of the D2D session. When it has data to send to another device, the device may transmit buffer status report (BSR) to the base station. The base station may respond with a grant of D2D scheduling assignment (SA) configured according to the previously sent parameters. For example, the message may be scrambled with a D2D temporary identity sequence. In some cases, the device may transmit a group identification (ID) code to the base station, and the group ID may be associated with an index, so an SA for that group can be reference by index.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may select a random access message type for establishing connectivity with a core network, the selecting between a first random access message type associated with a non-terrestrial radio access technology and a second random access message type associated with a terrestrial radio access technology. The UE may transmit, during or after a random access procedure to establish a connection with the core network, a random access message in accordance with the selected random access message type. The UE may communicate with the core network via the connection.

Abstract: Aspects described herein relate to communicating with one or more cells for receiving a multicast and/or broadcast service (MBS), and providing MBS continuity in device mobility scenarios. In an aspect, one or more cells for reselection from a current cell can be detected, where the current cell supports a UE interested MBS. The one or more cells can be evaluated for reselection based at least in part on whether the one or more cells support the UE interested MBS to determine a target cell for reselection. Cell reselection can be performed to the target cell.

Abstract: Wireless communications systems and methods related to on-demand ultra-reliable, low-latency communication (URLLC) are provided. In one embodiment, a base station (BS) receives, from a user equipment (UE) in a first cell frequency, a request for a protocol data unit (PDU) session over a network slice. The BS receives, from a core network entity, a resource configuration request for the PDU session over the network slice. The BS transmits, to the core network entity, a resource configuration response indicating a cause for rejecting the resource configuration request. In one embodiment, a UE transmits, in a first cell frequency of a network, a network registration request message requesting a network slice of the network that is not provided by the first cell frequency. The UE receives a network registration response message indicating the network slice is allowed based on a second cell frequency of the network providing the network slice requested.

Abstract: Location services for a user equipment (UE) are supported with a Network Exposure Function (NEF) serving as a focal point for any location request. An entity that needs the location of the UE sends a location request to the NEF in the home PLMN or Visited PLMN for the UE. The location request includes, e.g., a type of location request, a required location accuracy, a required response time or some combination of these. The NEF determines whether to use a Gateway Mobile Location Center (GMLC) or a serving Access and Mobility Management Function (AMF) for the UE to obtain the UE location based on the content of the location request and sends the location request to the GMLC or serving AMF accordingly. Additionally, if the serving AMF is used, a serving base station may obtain the UE location and send the UE location to the serving AMF.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may monitor for wake up signals (WUSs) from a network entity (e.g., satellite) of a non-terrestrial network based on a geographic area. For example, the UE may monitor for WUSs if the UE is within a geographic area. In other examples, a UE may monitor for WUSs according to an assigned location-based WUS group if a cell supports the WUS group. In some cases, a network entity or UE may select a WUS resource set based on a location parameter. In some cases, a network entity or UE may select a WUS group based on a location parameter. In some cases, one or more network entities may determine geographic areas where the network may use WUSs or WUS groups, or the one or more network entities may negotiate with the UE to determine such areas.
