Abstract: A cellular multiple-input and multiple-output, MIMO, system (10) comprises a base station (20) having a plurality of antennas (22) and a logic (21) which analyzes pilot signals received from a terminal (11-15) at the plurality of antennas (22) to obtain information about radio channel properties between the terminal (11-15; 100) and the plurality of antennas (22). The base station (20) assigns at least two terminals (11-13) of a plurality of terminals (11-15) to a same pilot time slot. The base station (20) requests at least two terminals (11-13) to transmit pilot signals in the allocated pilot time slot in such a manner that the at least two terminals (11, 12; 11-13) are prevented from transmitting their pilot signals simultaneously.

Abstract: A cellular multiple-input and multiple-output, MIMO, system comprises a base station having a plurality of antennas. Pilot signals are received by the base station in each frame of a sequence of frames (60). The base station analyzes the pilot signals to determine radio channel properties of radio channels between respectively each one of a plurality of terminals and the base station.

The frames of the second frame type (62, 69) are included periodically in the sequence of frames (60).
