METHOD AND APPARATUS FOR AGILE WIRELESS NETWORK SIGNAL ADAPTATION
First Claim
1. A method implemented by one or more integrated circuits comprising:
- selecting a channel for wireless network communications, the channel having a full bandwidth consisting of a sum between a primary portion and a non-primary portion of the channel;
transmitting signals in the primary portion and the non-primary portion of the channel;
detecting interference associated with the non-primary portion of the channel; and
using the one or more integrated circuits, in response to the detected interference, transmitting signals only in a reduced portion of the channel, the reduced portion including the primary portion, but having a reduced bandwidth less than the full bandwidth.

Abstract
According to certain general aspects, the present invention provides a wireless networking scheme that adaptively modifies the transmitted signal bandwidth to avoid interference from or to other devices or systems (e.g., 802.11p) and to meet regulatory requirements (e.g., DFS). In embodiments, if a transmitter according to the invention is operating in a channel with high bandwidth, and if interference is detected or needs to be avoided on a non-primary portion of the occupied bandwidth, the transmitter adaptively reduces the portion of the bandwidth used for transmission to minimize interference. This allows the transmitter to reduce interference or meet compliance requirements without significantly compromising throughput.

12. An apparatus comprising:
-
a transmitter that transmits signals in a channel for wireless network communications, the channel having a full bandwidth consisting of a sum between a primary portion and a non-primary portion of the channel; an interference detector that detects interference associated with the non-primary portion of the channel; and a signal adapter that, in response to the detected interference, causes the transmitter to transmit signals only in a reduced portion of the channel, the reduced portion including the primary portion, but having a reduced bandwidth less than the full bandwidth. - View Dependent Claims (13, 14, 15, 16, 17, 18)
