Abstract

A wireless resource scheduling method and device for NAN are disclosed. The wireless resource scheduling method for NAN can comprise the steps of: determining switching from a WiFi mode to a NAN mode by a NAN terminal of an AP function; when the NAN terminal of the AP function determines the switching to the NAN mode, transmitting a CTS-to-self frame on the WiFi mode by the NAN terminal of the AP function; switching from the WiFi mode to the NAN mode by the NAN terminal of the AP function; and transmitting, by the NAN terminal of the AP function, a NAN frame to a NAN terminal on the NAN mode, wherein the WiFi mode supports communication on the basis of a BSS and the NAN mode can support communication on the basis of a NAN cluster.

First claim

What is claimed is:

1 . A method of scheduling a radio resource for neighbor awareness networking (NAN), the method comprising:
transmitting, by a NAN terminal supporting a non-NAN mode for communicating based on a basic service set (BSS) and a NAN mode for communicating based on a NAN cluster, a clear to send (CTS)-to-self frame to other NAN terminals belonging to the NAN cluster, wherein the CTS-to-self frame includes information regarding a time period during which any frames are not transmitted by the other NAN terminals; and transmitting, by the NAN terminal, a management frame related to the NAN mode to the other NAN terminals after the time period according to the information has elapsed.

2 . The method of claim 1 ,
wherein the CTS-to-self frame is received by a plurality of non-NAN mode STAs operating in the non-NAN mode and the other NAN terminals, and wherein the plurality of non-NAN mode STAs set a network allocation vector (NAV) during the time period.

3 . The method of claim 2 ,
wherein the CTS-to-self frame further comprises a NAV setting target indication bit, wherein if the NAV setting target indication bit indicates a first value, the other NAN terminals and the plurality of non-NAN mode STAs set a NAV during the time period, and wherein if the NAV setting target indication bit indicates a second value, only the plurality of non-NAN mode STAs set the NAV during the time period.

4 . The method of claim 1 ,
wherein the management frame is one of a NAN sync beacon frame, a NAN discovery beacon frame, and a NAN service discovery frame.

5 . A neighbor awareness networking (NAN) terminal that supports a non-NAN mode for communicating based on a basic service set (BSS) and a NAN mode for communicating based on a NAN cluster for performing radio resource scheduling for NAN, the NAN terminal comprising:
a radio frequency (RF) unit configured for transmitting or receiving a radio signal; and a processor operatively coupled to the RF unit, wherein the processor is configured for: transmitting a clear to send (CTS)-to-self frame to other NAN terminals belonging to the NAN cluster, wherein the CTS-to-self frame includes information regarding a time period during which any frames are not transmitted by the other NAN terminals; and transmitting a management frame related to the NAN mode to the other NAN terminals after the time period according to the information has elapsed.

6 . The NAN terminal of claim 5 ,
wherein the CTS-to-self frame is received by a plurality of non-NAN mode STAs operating in the non-NAN mode and the other NAN terminals, and wherein the plurality of non-NAN mode STAs set a network allocation vector (NAV) during the time period.

7 . The NAN terminal of claim 5 ,
wherein the CTS-to-self frame further comprises a NAV setting target indication bit, wherein if the NAV setting target indication bit indicates a first value, the other NAN terminals and the plurality of non-NAN mode STAs set a NAV during the time period, and wherein if the NAV setting target indication bit indicates a second value, only the plurality of non-NAN mode STAs set the NAV during the time period.

8 . The NAN terminal in AP capability of claim 5 ,
wherein the management frame is one of a NAN sync beacon frame, a NAN discovery beacon frame, and a NAN service discovery frame.
