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.
