摘要： A system, method, and base station antenna for improved coverage in a cellular mobile telephony network. Each cell in the network has an area defined by azimuth and range limits. In the system, a first cell and a second cell are essentially adjacent to each other in azimuth. A third cell has an azimuth limit that is essentially equal to the total azimuths of the first and second cells, and has a range coverage that is shorter than the ranges of the first or second cells. The base station antenna forms separate “conventional” beams for the first and second cells, and forms a “near cell” beam for the third cell.

摘要： The invention discloses a system (200) for cellular mobile telephony, comprising a base station antenna (500, 600, 700) and a plurality of cells (203, 310, 320, 330). Each cell has an area defined by an azimuth (α1, a2) and a range (R0 R′), and the first (310) and second (320) cell cover respective areas, said areas being defined by first (α1,) and second (α2) azimuths and first and second ranges (Ro) respectively. The first and second cells are essentially adjacent to each other in azimuth, and the system also comprises a third cell (203, 330) with an area coverage defined by a third azimuth and a third range (R′). The third azimuth is essentially the same as, and coinciding with, the total azimuths of the first and the second cell, but the third cell has a range coverage which is much smaller than the first or second range coverages.

摘要： A transmitter for transmitting data in a cellular radio system is provided. The transmitter transmits data to User Equipment(s) using multiple transmitting antennas, using at least two polarization formers generating orthogonal polarizations of an input data stream. The transmitter further comprises a transmitter diversity arrangement adapted to receive input data to be transmitted to the User Equipment(s), where the transmitter diversity arrangement is connected to the input terminals of the polarization formers. By combining transmitter diversity with polarization former weights, orthogonality between multiple, in particular 4, transmitting antennas can be obtained.
