Abstract
A method and apparatus for an access point (AP) accessing a channel occupied by a neighboring AP within clear channel assessment (CCA) range. The method is implemented by setting a transmit null towards the neighboring AP, while acquiring accurate channel knowledge with minimal bandwidth penalty to surrounding networks, via a combination of sparse explicit sounding, and a following implicit channel estimation of the neighboring APs for updating the explicit data achieved by the sparse explicit sounding. An AP implementing the method is also disclosed.
