Abstract: Embodiments provide a method for transmitting a downlink control signal, and an apparatus. The method includes: sending, by a base station, one or more radio frames, where the one or more radio frames include a plurality of OFDM symbols that carry synchronization signals, each OFDM symbol that carries a synchronization signal is sent by using one or more downlink beams of the base station, and the OFDM symbol that carries the synchronization signal further carries a downlink control signal. The downlink control signal is placed in the OFDM symbol that carries the synchronization signal.

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.
