Methods and apparatus for scheduling mobile stations (MSs) to download
data and/or to control the rate of downloading to an MS from a base
station (BS) as a function of downlink channel condition information are
described. Artificial channel variations, which can be measured at the
MS, and feedback to a BS for scheduling purposes, are introduced through
the use of two or more transmitter antennas at a BS. Each of the antennas
transmits a signal at the same frequency having the same information
content, e.g., modulated data. However the signals are made to differ
with time in their phase and/or amplitude to introduce what appear to be
channel variations to the MSs.
