Abstract
Described herein are mechanisms to inform a first Neighbor Awareness Networking (NAN) device as to whether or not a second NAN device is connected to a dynamic frequency selection (DFS) master and/or whether the second NAN device is listening to the same DFS master as the first NAN device. In order for NAN client devices to operate in the 5 GHz band and be DFS compliant, all such devices that are communicating in a NAN peer-to-peer manner must either maintain association with a DFS master or must listen to the same DFS master for channel information.
Claims24
An apparatus for a wireless station (STA), the apparatus comprising:
- memory and processing circuitry, wherein the processing circuitry is to:
- encode a Neighbor Awareness Networking (NAN) service discovery frame to announce NAN services to peer devices or look for peer devices with which to establish a NAN connection;
- wherein the NAN service discovery frame is encoded to include a device capability attribute with a Dynamic Frequency Selection (DFS) Master flag to indicate whether the STA supports DFS master functionality;
- when operating as a NAN STA that is associated with or that listens to a DFS master, decode a frame from the DFS master that indicates availability of DFS channels and include no slots in the DFS channels as committed, potential, or conditional NAN availability slots if the decoded frame from the DFS master indicates that no committed NAN availability slots in the DFS channels are available.
A method for operating a wireless station (STA), comprising:
- encoding a Neighbor Awareness Networking (NAN) service discovery frame to announce NAN services to peer devices or look for peer devices with which to establish a NAN connection;
- wherein the NAN service discovery frame is encoded to include a device capability attribute with a Dynamic Frequency Selection (DFS) Master flag to indicate whether the STA supports DFS master functionality;
- when operating as a NAN STA that is associated with or that listens to a DFS master, decoding a frame from the DFS master that indicates availability of DFS channels and including no slots in the DFS channels as committed, potential, or conditional NAN availability slots if the decoded frame from the DFS master indicates that no committed NAN availability slots in the DFS channels are available.
A non-transitory computer-readable medium comprising instructions to cause a wireless access point (AP), upon execution of the instructions by processing circuitry of the AP, to:
- encode a Neighbor Awareness Networking (NAN) service discovery frame to announce NAN services to peer devices or look for peer devices with which to establish a NAN connection;
- wherein the NAN service discovery frame is encoded to include a device capability attribute with a Dynamic Frequency Selection (DFS) Master flag to indicate whether the STA supports DFS master functionality;
- when operating as a NAN STA that is associated with or that listens to a DFS master, decode a frame from the DFS master that indicates availability of DFS channels and include no slots in the DFS channels as committed, potential, or conditional NAN availability slots if the decoded frame from the DFS master indicates that no committed NAN availability slots in the DFS channels are available.
