Abstract

The invention discloses a transceiver (210, 215; 305, 310, 320, 330) for use in a cellular communications system (200, 300), arranged to communicate with at least one other transceiver in the system by means of technology for Multiple Input Multiple Output, MIMO. The transceiver is also arranged to control the function of a repeater (206, 207, 208, 209; 340) which is arranged to forward communication between the transceiver and said at least one other transceiver, said control being carried out as a result of measured performance parameters of the communication between the transceiver and said at least one other transceiver. In one embodiment, the function in the repeater (206, 207, 208, 209; 340) which the transceiver is arranged to control comprises activation and deactivation of the repeater.
