Abstract

See full text

A method and apparatus for discarding a buffered data in a wireless communication system is described. A central unit (CU) user plane (UP) of a gNB receives a buffered data discard indication from a CU-control plane (CU-CP) of the gNB, and discards buffered data for a user equipment (UE) based on the buffered data discard indication. Even after discarding the buffered data, UE context is still kept. The CU-CP is a logical node constituting the gNB that hosts a radio resource control (RRC) protocol and a packet data convergence protocol (PDCP)-C protocol, and the CU-UP is a logical node constituting the gNB that hosts a PDCP-U protocol.
