US 11,057,826 B2 · Scanning enhancements for next generation Wi-Fi channels

Abstract

Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide that an access point (AP) or a station (STA) may identify, from a set of channels in a radio frequency spectrum band, a subset of discovery channels. The discovery channels may be designated for discovery signaling for device association. An AP may transmit discovery information for associating with a STA over a discovery channel from the subset of discovery channels. In some examples, the AP may receive a probe request from a STA operating in an active scanning mode, and may transmit the discovery information in a probe response. In some examples, the AP may transmit the discovery information in a periodic signal, such as a beacon, to a STA operating in a passive scanning mode. The AP may receive an association request and associate with the STA.

Dependent claims

An apparatus for wireless communication at an access point, comprising:

a first interface;
a second interface;
and a modem coupled to the first interface and the second interface, wherein the modem is configured to:
identify, from a plurality of channels in a radio frequency spectrum band, a subset of discovery channels designated for discovery signaling for device association, the subset of discovery channels comprising a set of non-contiguous channels having a non-unitary periodicity;
and
output, via the first interface, discovery information to a station for determining whether to associate with the access point over a channel from the plurality of channels, the channel comprising a discovery channel of the subset of discovery channels.
