TRANSMISSION CONTROL METHOD AND DEVICE

摘要

A transmission control method. The transmission control method comprises: when detecting that high frequency downlink data transmission needs to be performed, a base station sends downlink data to a terminal at a high frequency; and the terminal sends, to the base station at a high frequency, control information used for assisting the base station to improve the quality of the high frequency downlink data transmission, so that the base station controls the high frequency downlink data transmission process according to the control information. Also disclosed are a base station and a terminal. By means of the present invention, a terminal can rapidly feed back control information at a high frequency in a high frequency downlink data transmission process, and the feedback delay is short.
