Abstract: Embodiments of the present disclosure relate to multi-path operation. According to embodiments of the present disclosure, a measurement report is transmitted to a base station on a first path between the UE and the base station, wherein the measurement report indicates channel quality information on one or more potential paths between the UE and the base station. A path addition command is then received from the base station, wherein the path addition command indicates the UE to add a path from one or more potential paths as a second path. The second path between the UE and the base station is then established based on the path addition command.

Abstract: A user equipment (UE) is configured to deactivate/activate a point-to-multipoint (PTM) link of a multicast radio bearer (MRB). The UE receives, from a base station of a wireless network, a multicast radio bearer (MRB) configuration, wherein the MRB includes configuration of a split MRB including a point to multipoint (PTM) link and a point to point (PTP) link, deactivates or activates the PTM link based on the MRB configuration, reestablishes a radio link control (RLC) associated with the PTM link and recovers a packet data convergence protocol (PDCP).

Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media for prioritizing data transmissions. According to embodiments of the present disclosure, in accordance with a determination that there is an overlap between a configured uplink grant and a dynamic uplink grant, a terminal device selects, from the configured uplink grant and the dynamic uplink grant, a target uplink grant for transmitting data to a network device. Thereby, the terminal device transmits data to the network device via the target uplink grant.

Abstract: Disclosed are embodiments for authentication and authorization in a 5G network between an edge enabler client (EEC) of a UE and an edge configuration server (ECS). The embodiment include performing primary authentication with the 5G network to obtain a KAUSF; generating a Kedge and a Kedge ID using the KAUSF and a subscription permanent identifier (SUPI); providing the Kedge and the Kedge ID to the EEC to cause it to compute a MACEEC using the Kedge and an EEC ID; and sending to the ECS an application registration request, the application registration request including the EEC ID, MACEEC, and Kedge ID.

Abstract: In some embodiments, during the SIP registration, the UE indicates in the REGISTER requests its support for ANBR as defined by ANBR attribute in the SDP and the P-CSCF indicates its support for the ANBR attribute in the SDP in the response for registration. In some embodiments, the P-CSCF serving a PLMN passes through the ANBR attribute in the SDP when the P-CSCF recognizes that the PLMN supports ANBR functionality. In some embodiments, the UE can include ANBR attribute in the SDP offer and answers when the P-CSCF indicates its support for the ANBR attribute in the SDP.
