    摘要: Aspects of the disclosure relate to relaying data between a PC5 remote UE and a network entity (e.g., 5G core network entity) via an inter-working function (e.g., N3IWF) over sidelink UE-to-NW relay access. In an example operation, a relay UE establishes a connection with the network entity and determines whether relay access to the network entity via an inter-working function device is supported at the relay UE. The relay UE then indicates, to the remote UE, support of the relay access to the network entity via the inter-working function device. The relay UE receives, from the remote UE, a request to relay data between the remote UE and the network entity via the inter-working function device, and thereafter, relays the data between the remote UE and the network entity via the inter-working function device based on the request. Other aspects and features are also claimed and described.

    摘要: Aspects of the present disclosure relate to wireless communications, and more particularly, to performing a handover on a per-data radio bearer (DRB) basis. In some examples, the disclosure is directed to indicating, to a source network entity, a make-before-break (MBB) handover capability of the UE, the MBB handover capability supporting MBB handovers for one or more DRBs identified by the source network entity. In some examples, the disclosure describes receiving, from the source network entity, configuration information for a handover from the source network entity to a target network entity, the configuration information identifying the one or more DRBs supported for the MBB handover.

    摘要: Methods, systems, and devices for wireless communication are described. A first user equipment (UE) may receive link capability information from a second UE that has a cellular wireless connection with a network entity of a cellular wireless network. The link capability information may be associated with a subscription of the second UE to the cellular wireless network. The first UE may establish a local wireless connection with the second UE based on the link capability information associated with the subscription of the second UE to the cellular wireless network. The first UE may communicate one or more messages with the network entity of the cellular wireless network via the second UE using first subscriber identity module (SIM) credentials of the first UE or second SIM credentials of the second UE based on establishing the local wireless connection with the second UE.

    摘要: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may be configured to communicate with a first base station, where the first UE is configured to relay wireless communications between a second UE and the first base station via at least a sidelink communication link between the first UE and the second UE. The first UE may receive, from the first base station, an indication for the first UE to perform a first handover procedure from the first base station to a second base station. The first UE may transmit, to the second UE via the sidelink communication link and based on receiving the indication to perform the first handover procedure, a sidelink transmission including a trigger for the second UE to perform a second handover procedure or a reselection procedure. The first UE may then communicate with the second base station based on performing the first handover procedure from the first base station to the second base station.

    摘要: Aspects of the disclosure relate to mechanisms for proximity service (ProSe) authorization and provisioning. A user equipment (UE) may be configured to support ProSe communication and may indicate this capability to a radio access network (RAN) and a core network during registration of the UE. Based on the ProSe indication, the RAN may select an access and mobility management function (AMF) that supports ProSe authorization and policy provisioning and forward a registration request indicating the UE supports ProSe communication to the selected AMF. Upon authorizing the UE for ProSe operation, the AMF may transmit a registration accept message including a ProSe supported indication to the UE. The UE may then initiate a ProSe session with another UE based on the ProSe supported indication in the registration accept message.
