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.

Abstract: Mobile devices implement a ranging mechanism that includes a lead responder receiving ranging measurement requests from two different initiators in the same DW cycle. At the beginning of the DW cycle the lead responder broadcasts and/or publishes a channel availability map that includes a list of slots and channels in which to respond to the ranging measurement requests based on a number of ranging operations supported in each slot within the DW cycle and based on an autonomously determined response sequence. If the lead responder responds to all ranging requests by all initiators in a DW cycle, secondary responders can perform ranging in the same or subsequent DW cycles. Upon exhausting all initiators paired with the lead responder, a secondary responder becomes the “active” responder that is chosen based on a prioritization scheme that is universal among the group of devices in the ranging operation.
