1. A method, comprising:
receiving, by an assisting radio access network (RAN) node from a host RAN node hosting a packet data convergence protocol (PDCP) entity, radio link control (RLC) activation information associated with a dedicated radio bearer (DRB) for uplink duplication; and
establishing, by the assisting RAN node, according to the RLC activation information, a medium control element (MAC) control element (CE) frame, to identify a state of each of secondary RLC entities of the DRB as in an active state or an inactive state.
