Abstract
The present invention relates to a method for allocating resources for a transmission of pilot signals of a plurality of terminals (18-23, 24-27) of a cellular multiple-input and multiple-output, MIMO, system. The cellular MIMO system (40) comprises at least a first base station (10) and a second base station (15), wherein each of the first and second base stations (10, 15) has a plurality of antennas (13) and a logic (12) which analyzes pilot signals received from a terminal (18-23, 24-27) at the plurality of antennas (13) to obtain information about radio channel properties between the terminal (18-23, 24-27) and the plurality of antennas (13). According to the method, the first base station (10) determines a first resource (1-3) used for transmission of pilot signals of a first terminal (18-23) and a usage type indicating a usage of the first resource (3). The usage type and information about the first resource (1-3) is transmitted from the first base station (10) to the second base station (15). The second base station allocates based on the usage type and the information about the first resource (1-3) a second resource (2) for a transmission of pilot signals of a second termin…
