Abstract: A method and an apparatus for aligning antenna beams in a high-low frequency co-site network, where the method includes performing antenna alignment of a low frequency beam with a communications device in order to establish a low frequency channel, and performing high frequency beam alignment of a high frequency antenna with the communications device using the low frequency channel. In the method, high frequency beam alignment of a high frequency antenna is performed using an established low frequency channel. Therefore, a technical problem that a high frequency beam alignment time of a high frequency antenna is long due to a narrow field of view of a high frequency beam can be avoided in order to quickly implement high frequency beam alignment of a high frequency antenna.

Abstract: A transmission control method is disclosed. The transmission control method includes: sending, by a base station, downlink data to a terminal at a high frequency when detecting that the downlink data needs to be transmitted at the high frequency; and sending, by the terminal to the base station at the high frequency, control information used for assisting the base station in improving transmission quality of the high frequency downlink data, so that the base station controls a transmission process of the high frequency downlink data according to the control information. Embodiments of the present invention further disclose 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 process in which downlink data is transmitted at a high frequency, and a feedback time is short.
