Abstract: Examples of the disclosure relate to managing Master Cell Group (MCG) configurations during PSCell (Primary Secondary Cell) changes. In examples of the disclosure a User Equipment comprises means for receiving, from a master node, preparation configurations for at least a first candidate target PSCell and a second candidate target PSCell, wherein same MCG configuration is shared among at least the first candidate target PSCell and the second candidate target PSCell. The User Equipment also comprises means for performing a PSCell change from a source PSCell to the first candidate target PSCell and retaining the preparation configurations after the PSCell change. The PSCell change is performed without a PCell change.

Abstract: Described herein is a user equipment, UE, configured to establish a connection towards a first network node (e.g. source DU) via a first cell supported by the first network node (source DU). The UE receives configuration information related to performing measurements for a target cell as candidate cell for a cell change, wherein the target cell is supported by a second network node (target DU), and determines further configuration information related to monitoring validity of a timing advance value related to the target cell. The UE is e.g. further enabled to send towards the first network node (source DU) a first (L1) measurement report including target cell measurement info, and to receive from the first network node (source DU) an instruction to acquire timing advance value for the target cell. The UE then acquires timing advance value for target cell, and monitors the validity of acquired timing advance value based on the further configuration. The UE may then send towards the first network node (source DU) information regarding validity and/or invalidity of the timing advance value of target cell.

Abstract: Systems, methods, apparatuses, and computer program products for reducing uplink interruption in dual active protocol stack (DAPS) handover. For example, the user equipment may transmit an indication either to a source cell or to a target cell that there is no more pending uplink medium access control and radio link control (re)-transmissions to be transmitted to the source cell, after the uplink switch to the target cell occurs during a DAPS handover. Based on the received indication, the network (e.g., the source cell or target cell) may perform one or more actions to enable forwarding of the uplink packets received from the user equipment by the target cell to a user plane function and/or serving gateway.
