Abstract: Systems and methods of segregating a SDF of a PDU session are described. The UE transmits a NAS message to the network. The NAS message indicates the SDF, the desired QoS, and a segregation indication that requests that the network establish a separate QoS flow for the SDF even if an existing QoS flow is able to support the specific QoS. The SMF decides whether or not to establish the separate QoS flow and updates filters in the UPF as well as providing a response to the UE containing a similar indication. The UE modifies resources related to the PDU session based on the response. The QoS is indicated as a 5QI and GBR or as a QFI of an existing QoS Flow on which the SDF is to be added if the separate QoS is not established. The QFI is in an unencrypted SDAP header of the NAS message.

Abstract: Methods, systems, and devices for offloading traffic flows without service disruption are disclosed herein. User equipment (UE) is configured to receive an indication that a current packet data network (PDN) connection can be optimized. The current PDN connection is established over a first PDN gateway (PGW). The UE requests connection over a new PDN connection to a same type of service as the current PDN connection without releasing the connection over the first PGW. The UE routes new traffic flows over a second PGW corresponding to the new PDN connection and routes old traffic flows over the first PGW.

Abstract: Disclosed are apparatuses for quality of service (QoS) flow to data radio bearer (DRB) mapping override bits. An apparatus of a user equipment (UE), includes one or more data storage devices, and one or more processors operably coupled to the one or more data storage devices. The one or more data storage devices are configured to store data corresponding to mapping of QoS flows to data radio bearers. The one or more processors are configured to map one or more QoS flows to a DRB in an uplink (UL) responsive to receipt, by the UE from a cellular base station, of a user plane packet in a downlink (DL) through the DRB if an override bit of the user plane packet indicates that reflective mapping should apply.

Abstract: Embodiments of a UE and methods for D2D communication are generally described herein. The UE may transmit, as part of an in-network communication session, a D2D discovery status message. The D2D discovery status message may indicate an initiation or termination of a D2D discovery operation at the UE and may indicate if the UE is announcing or monitoring as part of the D2D discovery operation. The D2D discovery operation may be at least partly for configuring a D2D communication session between the UE and one or more other UEs. The UE may transmit, as part of the D2D discovery operation, a D2D discovery signal for reception at one or more other UEs. The UE may transmit and receive D2D packets over a direct link to a second UE as part of the D2D communication session.

Abstract: Embodiments of a User Equipment (UE), an Evolved Node-B (eNB) and methods for communication are generally described herein. An UE may be configurable to operate as an eRelay UE. The eRelay UE may be configured to operate as a relay between an eNB and an eRemote UE. The eRelay UE may receive, from the eRemote UE, a message that includes an identifier of the eRemote UE for paging of the eRemote UE. The eRelay UE may determine whether a first paging message from the eNB includes the identifier of the eRemote UE. If it is determined that the first paging message includes the identifier of the eRemote UE, the eRelay UE may transmit, to the eRemote UE, a second paging message to page the eRemote UE. The second paging message includes the identifier of the eRemote UE.

Abstract: Disclosed herein are user equipment (UE) configured to communicate with a vehicle-to-everything (V2X) control function (CF) and a V2X Key Management Function (KMF). The UE includes processing circuitry configured to select a broadcast service from a plurality of available broadcast services and encode a key request message for transmission to the V2X KMF. The key request message includes a service identification (ID) of the selected broadcast service and identification of V2X security techniques supported by the UE. A key response message received from the V2X KMF in response to the key request message is decoded. The key response message identifies a V2X security technique of the V2X security techniques. The identified V2X security technique is execute to obtain security credentials provisioned by the V2X KMF. Data is encoded for transmission to a second UE during the selected broadcast service, where the encoding is based on the provisioned security credentials.

Abstract: Technology that allows PDN connections for a UE to be resumed efficiently after WLAN connectivity is lost and then regained are disclosed. A UE can have a multi-legged or multi-access packet-data-network (PDN) connection that is used to communicate with a WLAN and with an eNB. When WLAN connectivity is lost, the UE can send a WLAN-connectivity-loss communication to a PDN-GW via the eNB. A TWAG can also detect that the UE's WLAN connectivity has been lost and can send a suspension communication to the PDN-GW. The TWAG can also store PDN context information for the UE for a predefined period of time. When the UE regains WLAN connectivity, the UE can send a WLAN-link-control-protocol (WLCP) communication to the TWAG indicating that the UE wishes to resume one or more PDN connections that were previously suspended.
