Abstract:
A method for transmitting pilot signals in a cellular radio network, having in each cell, at least one base station configured to communicate with mobile stations located within its coverage area, the communication including (i) transmitting at least one data signal in a downlink direction using transmission directions that change in time, and (ii) transmitting information about the network to said mobile stations on control channels, said method comprising:said at least one base station transmitting at least one first pilot signal to all mobile stations within the cell, said pilot signal having a predetermined radiation pattern, said radiation pattern defining the coverage area, and said at least one base station transmitting a second pilot signal in said transmission directions that change in time, wherein said second pilot signal is incapable of carrying control information, and wherein said at least one data signal and said second pilot signal are transmitted using matching radiation patterns.
