Abstract

The present invention is a system (1200), base station (1100)/customer premise equipment (1150) apparatus, and method (400 450) for a two-stage quiet-period management mechanism that provides the required protection to incumbents (primary spectrum users) while supporting the desired QoS of secondary users participating in a cognitive radio network. In the first stage, a simple fast sensing (301) is done (e.g., energy detection) by all devices in the network. Depending on the result of the fast sensing, the second and possibly longer stage, herein termed fine sensing (302), is performed.
