Abstract
A long term evolution (LTE) protocol and a technology for designing an entity of the LTE protocol in layer 2 are provided. The method includes receiving a control message including packet data convergence protocol (PDCP) configuration information from an external communication device, determining whether data of a PDCP protocol data unit (PDU) received by the communication device is compressed according to the received PDCP configuration information, and when the data is compressed based on a result of the determination, decompressing the data.
