First Claim
Patent Images
1. A method for optimizing an energy detection threshold (EDT) parameter in wireless communications, comprising:
- determining, in a clear channel assessment (CCA) calculation device, an upper bound and a lower bound for the EDT parameter;
calculating, in the CCA calculation device, a value of the EDT parameter;
bounding, in the CCA calculation device, the EDT parameter by the upper bound and the lower bound; and
updating, in the CCA calculation device, the EDT parameter, whereby the EDT parameter is optimized.

Abstract
A method and apparatus are directed toward optimizing clear channel assessment (CCA) parameters in a wireless local area network having an access point (AP) and at least one station. An upper bound and a lower bound for an energy detect threshold (EDT) parameter are determined. A value of the EDT parameter is calculated and is bound by the upper bound and the lower bound. The EDT parameter is updated. The method can be performed at each station or at the AP, with the updated CCA parameters being signaled to each station associated with the AP.

11. A wireless station, comprising:
-
a receiver configured to receive a wireless signal on a channel; an energy detector configured to receive an output from the receiver and detect an energy associated with the received signal; a channel availability determination device configured to receive an output from the energy detector and an energy detect threshold parameter (EDT) as inputs and determine from the inputs if the channel is busy; and a clear channel assessment (CCA) calculation device configured to provide the EDT to the channel availability determination device and configured to optimize the EDT, the optimizing comprising; determining an upper bound and a lower bound for the EDT parameter; calculating a value of the EDT parameter; bounding the EDT parameter by the upper bound and the lower bound; and updating the EDT parameter, whereby the EDT parameter is optimized. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
