METHOD AND APPARATUS FOR PERFORMING INTEGRITY VERIFICATION IN WIRELESS COMMUNICATION SYSTEM

WIPO Patent Application WO/2019/182249

A1

The present invention relates to a method for reporting integrity verification failure by a user equipment in a wireless communication system. In particular, the method includes the steps of: receiving a data unit from a network; performing integrity verification using the data unit; and when the integrity verification fails, reporting information about the integrity verification failure to a network. Especially, the information about the integrity verification failure includes a radio bearer identity associated with the integrity verification failure and at least one PDCP COUNT value associated with the radio bearer identity.
