Abstract
A method and transmitter for generating broadcast beam patterns in massive MIMO systems, the transmitter comprising a rectangular antenna array with a number Nof antenna elements in the horizontal direction and a number Nof antenna elements in the vertical direction. The MIMO transmitter generates broadcast beam patterns with determined beam widths in horizontal and vertical dimensions to cover a sector area of a cell by the rectangular antenna array radiating N×Nradiofrequency signals at a carrier frequency, the sector area being where a user equipment requests from the MIMO transmitter access to the cell. The beam widths in horizontal and vertical directions are determined by using an optimum set of complex excitation coefficients calculated from a discretized continuous-space array factor ψ(θ,φ), which is based on a discretization over the elevation angle θ and the azimuth angle φ of the antenna elements.
