Abstract: A method, an apparatus, and a computer-readable medium for wireless communication are provided. An apparatus is configured to communicate over a primary channel via a first set of antennas and over the primary via a second set of antennas. The second set of antennas is switched from the primary channel to a secondary channel when the communication over the primary channel is idle. A channel availability checks (CACs) is performed on the secondary channel when the primary channel is idle to determine whether radar signals are detected on the secondary channel.
