Abstract: Apparatuses and methods in a communication system are provided. A first radio resource connection, RRC, with a Radio Access Network, RAN, node is established (502) by a device, the connection having a first Radio Network Temporary Identifier and being associated with a first subscription identity. An RRC setup procedure for establishing a second RRC is performed (504), the connection being associated with a second subscription identity. During or after the RRC setup it is indicated to the RAN node that the device has an existing radio resource connection with the node. A second Radio Network Temporary Identifier associated with the second radio resource connection and an additional Radio Network Temporary Identifier common to the first and second radio resource connections are received (506) and the common Identifier is used (508) for communication with the RAN node.

Abstract: A method and apparatus may include receiving, by a user equipment from a source cell, a first configuration configured for conditional handover and dual active protocol stack handover with a reduced target cell configuration, and a second configuration configured for conditional handover only. The method may further include determining, by the user equipment, the availability of at least one radio link associated with the source cell. The method may further include performing, by the user equipment, a conditional handover procedure according to at least one of the received configurations based upon the determination.

Abstract: Methods and apparatus, including computer program products, are provided for switching flow separation in dual connectivity. In some example embodiments, there may be provided a method that includes suspending, at the user equipment, at least one bearer and corresponding quality of service filter, when an access node is added as a secondary base station providing dual connectivity to the user equipment; switching, by the user equipment and in response to the added secondary base station, one or more packets to at least a secondary bearer at the added secondary base station; and reverting, by the user equipment, to the suspended at least one bearer and corresponding quality of service filter, when the added secondary base station is released as a connection at the user equipment. Related systems, methods, and articles of manufacture are also described.

Abstract: Example embodiments of the present disclosure relate to store-and-forward operations in non-terrestrial networks (NTN). In an aspect, a terminal device receives, from a network device of a NTN, data priority information associated with at least one store-and-forward operation performed by the network device in the NTN. The terminal device performs, based on the data priority information, an operation for uplink data of the terminal device. In this way, the limitations on the storage of the satellite and the feeder link capacity are solved. The data transmission is ensured, and the storage of the satellite is maximally utilized.

Abstract: Various example embodiments relate to a solution for non-terrestrial network communication. A user device for non-terrestrial network communication may be configured to determine that a connection to a non-terrestrial network having a discontinuous coverage is unavailable, the non-terrestrial network providing at least one cell serving the user device; obtain data relating to cell availability of the at least one cell; determine a backoff time associated with a subsequent non-terrestrial network search based at least partly on the data relating to cell availability; and initiate a cell search of the non-terrestrial network again after expiration of the backoff time.
