Abstract
There is provided mechanisms for generating cell-specific signals using an antenna array with dual-polarized antenna elements. A method is performed by a network device. The method comprises obtaining antenna weights for two sector-specific signals, each sector-specific signal giving rise to a respective sector-specific radiation pattern. The method comprises generating a first cell-specific signal, the first cell-specific signal giving rise to a first cell-specific radiation pattern, wherein antenna weights for the first cell-specific signal are determined such that the radiation pattern matches both sector-specific radiation patterns. The method comprises generating a second cell-specific signal, the second cell-specific signal giving rise to a radiation pattern identical to the first cell-specific radiation pattern, wherein antenna weights for the second cell-specific signal are identical to the antenna weights for the first cell-specific signal except that the first cell-specific signal and the second cell-specific signal have mutually orthogonal polarization.
