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