SOFT ACCESS POINT MASTER MODE USING DUAL WIDEBAND CHANNELS
First Claim
1. A method of wireless communication, comprising:
- establishing a primary channel in a first radar subband and a secondary channel in a second radar subband;
detecting a radar signal in the first radar subband;
moving the secondary channel to a non-radar subband based at least in part on detecting the radar signal; and
moving the primary channel to the second radar subband based at least in part on detecting the radar signal and moving the secondary channel.

Abstract
Methods, systems, and devices are described for wireless communication at an AP. A station (STA) serving as a soft access point (SAP) in master mode may be configured to support communication over two radar channels (e.g., a primary and secondary channel) simultaneously. The STA may detect radar on the primary channel and move the primary channel to the secondary channel; meanwhile, the secondary channel may be moved to a channel in a non-radar subband. In some cases, the STA may establish a primary channel in a non-radar subband and then advertise a single bandwidth capacity. the STA may then perform a channel availability check (CAC) on a radar subband. If the CAC is successful, the STA may establish a secondary channel on the radar subband (or move the primary channel to the radar subband) and advertise a dual bandwidth capacity.
