USER SCHEDULING METHOD AND DEVICE FOR TIME DIVISION DUPLEX MULTIPLE-INPUT MULTIPLE-OUTPUT DOWNLINK TRANSMITTING SYSTEM

摘要

A user scheduling method and device for time division duplex multiple-input multiple-output downlink transmitting system. The method includes: the step of obtaining gain, obtaining the effective gain of each of at least two usable sub-channels, according to the channel gain of at least two usable sub-channels of active user and the correlative coefficient between at least two usable sub-channels; the step of obtaining a preferred service sub-channel, selecting a usable sub-channel from at least two usable sub-channels as the preferred service sub-channel according to the effective gain; the step of obtaining a subordinate service sub-channel, recalculating the effective gain according to the correlative coefficient between the remainder usable sub-channel and fresh selecting service sub-channel, and selecting the subordinate service sub-channel according to the recalculated effective gain.
