US 9,854,625 B2 · Method and apparatus for transmitting signal by NAN terminal in wireless communication system

Abstract

A method for transmitting a signal by a neighbor awareness networking (NAN) terminal in a wireless communication system, according to embodiment of the present invention, comprises the steps of: sensing a medium in a discovery window; selecting a back-off count value when the medium is in an occupied state; and transmitting a service discovery frame after performing countdown on the basis of the back-off count value, wherein an interval in which the back-off count value is determined on the basis of at least one of an interval in which a back-off count value for transmitting a synchronization beacon frame is selected, the length of the discovery window, and a hop count value of the terminal.

A method of transmitting a signal by a NAN (neighbor awareness networking) terminal in a wireless communication system, the method comprising:

sensing a medium within a discovery window;
selecting a back-off count value when the medium is in an occupied state;
and
transmitting a service discovery frame after performing countdown based on the back-off count value,
wherein an interval for selecting the back-off count value is determined based on at least one selected from the group consisting of an interval for selecting a back-off count value for transmission of a synchronization beacon frame, a length of the discovery window, and a value of a hop count of the terminal.
