Disclosed is a communication method. The method comprises: a base station and a first user equipment perform beam scanning alignment on a first sub-frame, so as to determine a beam in the first sub-frame for sending data, wherein the number of beams for sending data is greater than or equal to one; and when using the beam to send data to the first user equipment, the base station sends beam information about the beam for sending the data, wherein the beam information at least contains identification information about the beam and a synchronization signal, the synchronization signal is used for synchronizing a second user equipment and the base station, and the identification information about the beam is used by the first user equipment and the second user equipment to identify the beam sent by the base station. Also disclosed is a base station and a user equipment. By means of the present invention, the time of scanning alignment can be reduced, thereby facilitating quick access of a user that has not accessed previously. |
