METHOD AND APPARATUS FOR REDUCING OVERHEAD FOR INTEGRITY CHECK OF DATA IN WIRELESS COMMUNICATION SYSTEM

摘要

The present invention relates to a method and apparatus for reducing overhead for integrity checking of data in a wireless communication system, and a method for reducing an overhead for a message authentication code of a control message in a wireless communication system, Determining whether the message authentication code included in the control message is valid by comparing the identifier of the first authentication key used in the control message with the identifier of the second authentication key; Counting the number of occurrences of the control message including the invalid message authentication code when the number of times of generation of the control message including the invalid message authentication code is not less than a predetermined threshold value, Quot;
