Abstract: Embodiments of the present invention disclose an interleaved polarized multi-beam antenna, including: at least one dual-polarized antenna element, where the dual-polarized antenna element includes a +45-degree-polarized first antenna element and a −45-degree-polarized second antenna element; and a first Butler matrix and a second Butler matrix, where the first Butler matrix is connected to the first antenna element so that the first antenna element transmits a first target beam, and the second Butler matrix is connected to the second antenna element so that the second antenna element transmits a second target beam. The first target beam and the second target beam in the embodiments are alternately arranged, and any two adjacent first target beam and second target beam have different polarization characteristics; therefore, complexity, a loss, and costs of implementation of a Butler matrix can be effectively reduced, and interference between adjacent multiplexed beams can be effectively decreased.

Abstract: 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.
