| Abstract: | 5G uses a large-scale array antenna design and beamforming technologies. In different wireless coverage environments, different broadcast beam weights can be configured to generate different combinations of beamforming beams with different tilts, azimuths, horizontal beamwidths, and vertical beamwidths. It can meet the coverage requirements of different radio environments and provide new ideas and methods for network coverage optimization. Based on the technical level of 5G networks, this paper analyzes the formulation of broadcast beam weight schemes. Based on MDT data, we formulate a beam weight matching scheme to guide coverage optimization and user camping optimization in the initial stage of 5G network construction. |
