1. A multi-antenna diversity scheduling method, comprising:

  • transmitting pilot signals through x transmit antennas, wherein the pilot signals on 1 to x−

    1 transmit antennas are a product of pilot symbols and a phase sequence, wherein the phase sequence changes with at least one of;

    time and frequency, wherein 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 transient CQI value and a scheduling algorithm, scheduling the user to transmit data, wherein;

    the product of the pilot symbols and the phase sequence, comprising
