Methods and apparatus are presented for improving the feedback of channel
information to a serving base station, which allows a reduction in the
reverse link load while allowing the base station to improve the forward
link data throughput. Over a channel quality indicator channel, three
subchannels are generated; the re-synch subchannel, the differential
feedback subchannel, and the transition indicator subchannel. The
information carried on each subchannel can be used separately or together
by a base station to selectively update internal registers storing
channel conditions. The channel conditions are used to determine
transmission formats, power levels, and data rates of forward link
transmissions.
