METHODS AND APPARATUS FOR TRANSMITTING INFORMATION BETWEEN A BASESTATION AND MULTIPLE MOBILE STATIONS |
摘要 |
Methods and apparatus for scheduling mobile stations (MSs) to download data to 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. Multiple signals having the same transmission frequency and information content are received and interpreted as a single composite signal by a receiving MS. |
