Method of selectively applying a PDCP function in wireless communication system

摘要

Disclosed is a wireless communication system and terminal for providing a wireless communication service, and more particularly, a method of selectively applying a PDCP function based on data characteristic transmitted through a radio bearer in an Evolved Universal Mobile Telecommunications System (E-UMTS) evolved from a UMTS, Long Term Evolution (LTE) System or LTE-Advanced (LTE-A) system.

1. A method of applying an integrity protection in wireless communication system, the method comprising:
receiving, by a Relay Node (RN), a configuration message from a network, wherein the configuration message includes an indicator for indicating whether the integrity protection should be used by the Relay Node (RN); and using, by the Relay Node (RN), the integrity protection according to the indicator included in the configuration message, wherein when the integrity protection is used, a format of a data unit for a Relay Node Data Radio Bearer (RN DRB) includes a D/C (Data/Control) field, one or more reserved fields, one or more fields for a sequence number of the data unit, one or more data fields, and one or more fields for information related to the integrity protection.
