Abstract
This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for communicating channel selection constraints in a network having multiple access points (APs). In one aspect, a root AP may assist with channel selection (assignment) for the multiple APs. A first AP can provide channel operating constraints to the root AP to indicate one or more operating constraints for a particular channel that may be used by the first AP. The operating constraints may be based, at least in part, on a hardware characteristic of the first AP. For example, an operating constraint may indicate a minimum channel separation or a maximum transmit power to consider when the particular channel is used concurrently with another channel. In another aspect, the first AP can communicate a channel selection error and error code when a particular channel cannot be used due to an operating constraint.
