Abstract

See full text

An apparatus of a Radio Access Network (RAN) node, a system, and a method. The apparatus includes one or more processors to, during a non-dual connectivity (non-DC) radio link control (RLC) acknowledged mode (AM) handover of a user equipment (UE) from a source RAN node to the RAN node: process a message including information on at least one of an uplink (UL) COUNT value, a downlink (DL) COUNT value, or a hyper frame number (HFN) corresponding to UL or DL packet data convergence protocol (PDCP) data units (DUs) communicated between the UE and the source RAN node; determine the at least one of the UL COUNT value, the DL COUNT value or the HFN from the message; and process the PDCP DUs based on the at least one of the UL COUNT value, the DL COUNT value.
