Abstract
An apparatus of a base station (BS) of a radio access network (RAN) comprises memory and processing circuitry. The processing circuitry includes a central unit (CU) portion and a distributed unit (DU) portion that implement a BS multi-layer protocol stack divided between the CU portion and the DU portion. The processing circuitry initiates a handover to change a serving cell of user equipment (UE). The handover includes a change in a portion of logical layers of the BS multi-layer protocol stack, and the processing circuitry encodes an information element for transmission to the UE indicating logical layers of a UE multi-layer protocol stack implemented in the UE to be reset by the UE in association with the handover.
