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.

摘要： An antenna device for a radio base station in a mobile cellular telephony network. The device includes a first sub-antenna with a first feed network for distributing signals within the first sub-antenna, and a second sub-antenna with a second feed network for distributing signals within the second sub-antenna. The first and second feed networks are connected to a common main feed network, thus providing the device with a single feed port. A first controller controls one or both of the sub-antennas, and may introduce time delays in signals being transmitted or received by one or both of the sub-antennas. The device may also include a second controller for controlling the common main feed network.

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.
