Abstract

A method for operating a user plane protocol stack by user equipment (UE) in a connectionless communication system is provided. The method includes dividing a destination ID into a first part and a second part, transmitting a scheduling assignment including a first part of the destination ID, and transmitting a medium access control (MAC) protocol data unit (PDU) including a UE identifier and a second part of the destination ID in a MAC header of the MAC PDU.

Description

Technical field [0001] The present disclosure relates to an apparatus and method for operating a user plane protocol stack in a connectionless communication system. Background technique [0002] In a traditional connection-oriented wireless communication system, a data radio bearer is established through explicit signaling between a user equipment (UE) and a base station (BS). [0003] Applications or Internet Protocol (IP) full of different quality of service (QoS) are mapped to different radio bearers. [0004] The user plane protocol stack used for data transmission / reception includes a packet data convergence protocol (PDCP) layer entity, a radio link control (RLC) layer entity, and a medium access control (MAC) layer entity. [0005] The data of each radio bearer is processed by an independent PDCP layer entity and an independent RLC layer entity configured at the timing of the radio bearer establishment through explicit signaling. The radio bearer is identified by the radio bea...
