Publisher's Synopsis
According to a communication method and a base station that are provided in embodiments of the present invention, the base station transmits a broad beam that covers a sector of the base station and narrow beams whose coverage areas completely fall within a coverage area of the broad beam, which implements that under a premise that a coverage area of the sector of the base station maintains unchanged by using the broad beam, enhanced coverage of the sector is further achieved by using the narrow beams, thereby improving spectral efficiency. In the solutions, a sector coverage area of the broad beam transmitted by the base station still maintains unchanged, and therefore, a coverage relationship between sectors is not affected. In addition, neither an additional site backhaul resource nor additional standardization support is required in the solutions.
