TRANSMIT OPPORTUNITY DETECTION
First Claim
1. A method comprising:
- calculating a differential metric based on a first metric and a second metric for a primary network, the primary network having a medium shared with a secondary network, the first metric based on a first distribution of traffic on the primary network and corresponding to absence of a perturbation of the medium, the second metric based on a second distribution of traffic on the primary network and corresponding to a perturbation of the medium from a node on the secondary network; and
selecting a transmission power for the node based on the differential metric.

Abstract
The present application discusses, among other things, apparatus and methods for detecting and using a excess capacity on a wireless network medium. A method embodiment includes calculating a differential metric based on a first metric and a second metric for a primary network. The primary network can have a medium shared with a secondary network. The first metric can be based on a first distribution of traffic on the primary network and can correspond to absence of a perturbation of the medium. The second metric can be based on a second distribution of traffic on the primary network and can correspond to a perturbation of the medium from a node of the secondary network. The method can include selecting a transmission power for the node based on the differential metric.

11. An apparatus comprising:
-
a receiver configured to receive information corresponding to a primary network, the primary network having a medium shared with a secondary metric; a service module to generate a first service metric corresponding to a signal to noise ratio (SNR) of the received information in absence of a perturbation on the medium and to generate a second service metric corresponding to a SNR of the received information in view of the perturbation; a processor configured to generate a result based on a first comparison of the first service metric and the second service metric and configured to select a transmission parameter based on the result; and a transmitter configured to transmit information using the secondary network and using the transmission parameter, the transmitter configured to provide the perturbation. - View Dependent Claims (12, 13, 14, 15)
