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.
