Abstract:
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 wherein s[m,n] is a pilot symbol on subcarrier m at the nth orthogonal frequency division multiplexing (OFDM) pilot slot, is a phase sequence, θ n is a sequence that changes with time periodically within [−π,π], τ is a cyclic delay, and N is number of inverse fast Fourier transformation (IFFT) points; if x−1 antennas transmit products of the pilot symbols and the phase sequence, a CQI value returned by the kth user is: wherein h
