Abstract: The present invention provides a multi-antenna diversity scheduling method and apparatus. The method includes: transmitting pilot signals through x transmit antennas, where pilot signals on 1 to x−1 transmit antennas are a product of pilot symbols and a phase sequence, the phase sequence changes with at least one of time and frequency, the phase sequence changes more frequently than a user channel, and x is a positive integer greater than or equal to 2; receiving a transient channel quality information (CQI) value returned by a user according to the pilot signals; and according to the CQI value and a scheduling algorithm, scheduling the user to transmit data.
