Method and apparatus for providing link quality feedback to a transmitter
in one embodiment, a periodic link quality message is transmitted on a gated channel,
while continuous differential indicators are transmitted. Between quality messages,
the differential indicators track the quality of the link. The periodic quality
messages provide synchronization to the transmitter and receiver. A coding is applied
to the feedback information identifying the transmitter, in one embodiment, a remote
station includes a differential analyzer (212) to determine the change in
successive channel quality measurements. In an alternate embodiment, link quality
feedback information is gated according to channel condition.
