The disclosure discloses a method and a device for frequency selective scheduling using channel symmetry. The disclosure can use the change of signal power of a Sounding Reference Signal (SRS) received at eNodeB end which is measured in the same band at different time, to adjust the Modulation and Coding Scheme (MCS) level or Signal to Interference plus Noise Ratio (SINR) corresponding to this band position, and thus to modify and provide the frequency selective scheduling information. The method and device receive the symmetry of useful signal power and obtain downlink frequency selective scheduling information by using Time Division Dual (TDD) system, thereby effectively improving the loss of the system performance caused by the inaccurate measurement of Channel Quality Indicator (CQI) due to feedback delay and feedback frequency, substantially increasing the probability of correct demodulation of issued data at receiving end, and effectively improve system performance. |
