A METHOD AND APPARATUS FOR TRANSMISSION MODE SELECTION

摘要

A dynamic transmission mode selection for a MIMO enabled multi carrier cellular radio system enabling dynamic selection of MIMO mode (or switching to a non-MIMO mode) is provided by transmitting a mode selection command as a layer 1 command. Hereby, the base station can be set to control the transmission mode and there is no need to involve a control node when selecting transmission mode. As a result, not only will the mode selection be more dynamic, but there will be less signaling between the base station and the control node of a cellular radio system.
