METHOD AND DEVICE FOR ADAPTIVE TRANSMISSION MODE SCHEDULING

摘要

Disclosed are a method and device for adaptive transmission mode scheduling. The method comprises: estimating the spectral efficiency of two transmission modes periodically according to a channel quality indicator (CQI) reported by a terminal and an outer loop adjustment parameter ?MCS maintained by a base station; correcting the spectral efficiency when a preset condition is satisfied; and selecting the transmission mode with the higher spectral efficiency as the transmission mode for the current scheduling. In the present invention, the transmission mode is selected based on the spectral efficiency, and the MIMO transmission mode with higher spectral efficiency may be selected, so the system throughput is effectively improved, and the problem of the incorrectly selected transmission mode and the poor system throughput performance caused by the incorrect rank indicator (RI) reported by a terminal in the downlink transmission mode 3 of a dual-antenna LTE system is solved.
