    Abstract: The present disclosure relates to a technique for enabling secondary-cell (SCell) operation during dual active protocol stack handover (DAPS-HO). For this purpose, a command for the DAPS-HO is modified at a source network node such that it causes a UE to maintain, among an available set of source SCells configured by the source network node for the UE, at least one source SCell active during the DAPS-HO, as well as to activate, among an available set of target SCells configured by a target network node for the UE, at least one target SCell during the DAPS-HO. By using such a modified command for the DAPS-HO, the UE may use the SCells of the source and target network nodes during the DAPS-HO, thereby resulting in a higher user plane throughput compared to that provided by using the single PCell operation only.

    Abstract: A user equipment of a telecommunications network comprising: at least one processor; and at least one memory storing instructions that, when executed by the at least one processor, cause the user equipment at least to: establish a connection between the user equipment and a first network node of the radio access network, the first network node supporting a first cell, derive in the user equipment a reference configuration relating to the first cell; wherein the reference configuration includes information related to a first bearer configuration; receive in the user equipment a target configuration related to a cell change from the first cell towards a second cell, wherein the target configuration includes information related to a target bearer configuration; and in response to an update of the first bearer configuration to an updated first bearer configuration, derive in the user equipment a related updated reference configuration and receiving in the user equipment a delta-over-target configuration, the delta-over-target configuration including information related to differences between an updated target bearer configuration and the target bearer configuration.

    Abstract: There is provided a method, computer program, and apparatus for causing an apparatus for a first access node to perform: establishing a connection towards a user equipment via a serving cell supported by the first access node; instructing the user equipment to obtain a first timing advance value for a target cell supported by a second access node, wherein the first timing advance value indicates a timing for transmitting uplink transmissions to the target cell; receiving, from the user equipment, an indication that the first timing advance value is or will soon be invalid; and determining whether to instruct the user equipment to obtain a second timing advance value for the target cell in dependence on the received indication, the second timing advance value being obtained later in time than the first timing advance value.

    Abstract: There is provided a method, comprising: communicating a first data session on a first network slice with a source network node; receiving an indication indicating whether or not mapping the first data session to a second data session at a target network node requires switching to a second network slice, wherein the user equipment is equipped with a dual active protocol stack enabling the user equipment to communicate with the source network node and with the target network node during the handover process of the apparatus from a source cell provided by the source network node to a target cell provided by the target network node; deciding to continue the first data session on the first network slice with the source network node during the handover process; and deciding, based on the indication, when to start user plane data communication on the second data session with the target network node.
