1. A method of operating a wireless local area network station comprising the steps of:
- establishing a variable carrier detect threshold level, so as to define a range of signal levels above which received signals are processed;
establishing a variable defer threshold level, above which transmission of signals is deferredreceiving a carrier signal having a corresponding power signal level;
transmitting a signal when said power signal level is below said defer threshold; and
processing said carrier signal intended for said network station when said power signal is above said variable carrier detect threshold level.

Abstract
A method and system of operating a wireless local area network station adapted to transmit and receive a signal within a communication cell. The method includes the steps of establishing a carrier detect threshold level, establishing a defer threshold level, and transmitting a signal when the signal level detected by the network station is above the defer threshold level. Additionally, the method further includes the step of receiving a signal transmission intended for the network station when the power of the received signal transmission is above the carrier detect threshold level.

9. A wireless local area network station adapted to transmit and receive a signal within a communication cell, comprising:
-
a carrier detect threshold circuit configured to receive a carrier signal having a power signal level, said carrier detect threshold circuit generating a carrier detect indication signal when said power signal level is substantially equal or larger than a variable carrier detect threshole level, so as to define a range of signal levels above said variable carrier detect threshole level wherein received signals are processed; a defer threshold circuit configured to receive said carrier signal having said power signal level, said defer threshold circuit generating a defer indication signal when said power signal level is substantially equal or larger than a specifiable defer threshold parameter, above which transmission of signals is deferred; and a signal processing circuit coupled to said carrier detect threshold circuit and said defer threshold circuit so as to receive said carrier detect indication signal and said defer indication signal such that said signal processing circuit processes signal received by said network station in response to said carrier detect indication signal and said signal processing circuit defers transmission of signals by said network station in response to said defer indication signal. - View Dependent Claims (10, 11, 12, 13, 14, 15)
