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 sequence of frames (60) comprises frames of a first frame type (61, 63, 64, 68) and frames of a second frame type (62, 69). Each frame of the second frame type (62, 69) have a greater number of time slots in which the base station receives the pilot signals than each frame of the first frame type (61, 63, 64, 68). The frames of the second frame type (62, 69) are included periodically in the sequence of frames (60).

Abstract: A mobile communication network comprises a first cell (200) and a second cell (210, 220, 230, 240) arranged in a coverage area of the first cell (200). A node (100) of the mobile communication network obtains positioning data of a UE (11, 12, 13, 14, 15, 16). The node (100) correlates the positioning data to a coverage area of the second cell (210, 220, 230, 240). Depending on the correlation of the positioning data and the coverage area of the second cell (210, 220, 230, 240), the node (100) selects between an active state and an inactive state of the second cell (210, 220, 230, 240). In accordance with the selected state, the node controls a base station of the second cell (210, 220, 230, 240).

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.
