Abstract: Systems, methods, apparatuses, and computer program products for survival time dependent flexible handover execution are provided. One method may include providing, by a network node, at least one handover execution condition to at least one user equipment. The at least one handover execution condition may include one or more delta values with respect to one or more actual handover execution conditions to allow for early and/or late execution of a handover by the at least one user equipment. The method may also include indicating, to the at least one user equipment, a transfer interval and/or a survival time information for which the at least one handover execution condition is taken into account.

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: In this invention, when a serving distributed unit informs target distributed unit via a central unit about a target reference, it is proposed to use, signal index X/indices X1 . . . Xn for PDCCH transmissions or PUSCH receptions or a RACH-less handover:
Send by a distributed unit of the serving cell towards a distributed unit of a target cell one of before, upon, or after transmission of a layer 1 serving cell change command to a user equipment, signaling comprising configuration information associated with the user equipment to perform a random access channel less handover of the user equipment to the target cell, wherein the configuration information informs the target cell about at least one target reference signal index that shall be used for at least one of at least one physical downlink control channel transmission or at least one physical uplink shared channel reception.-

Abstract: A method includes receiving, by a first network node that is configured as a master node from a second network node that is configured as a source secondary node for dual connectivity for a user device, control information indicating whether or not the first network node may receive from the second network node an updated measurement configuration based on a list of accepted target Primary Secondary Cells (PSCells) that are accepted by the target secondary node among a list of candidate target PSCells; sending to the user device, a conditional reconfiguration message including the initial measurement configuration that is based on the list of candidate target PSCells if the control information indicated that the first network node will not receive from the second network node an updated measurement configuration; and otherwise, sending a conditional reconfiguration message including the updated measurement configuration that is based on the list of accepted target PSCells.
