METHOD AND APPARATUS FOR MAINTAINING NAN DATA LINK IN WIRELESS COMMUNICATION SYSTEM

摘要

The present specification may provide a method for maintaining an NAN data link by an NAN terminal in a wireless communication system. The method for maintaining an NAN data link comprises the steps of: forming an NDL with another NAN terminal; performing an NDL schedule in at least one time block between the another NAN terminal and a discovery window; and performing data exchange on the basis of the another NAN terminal and a NDL schedule. When the NDL schedule is performed, a first frame, which includes keep-alive information indicating the awake state of a first NAN terminal in a first time block, may be sent to the another NAN terminal.
