The present invention relates to a wireless communication system, and more particularly, discloses a method and an apparatus for mode switching between a multi-cell coordinated communication mode and a single-cell MIMO communication mode. A method for dynamically switching a communication mode according to one embodiment of the present invention comprises: a step of generating and transmitting first feedback information in accordance with a first communication mode; a step of switching the first communication mode into a second communication mode interlocked with the first communication mode; and a step of generating and transmitting second feedback information in accordance with the second communication mode. The first communication mode is one of a multi-cell coordinated multi-point (CoMP) communication mode and a single-cell multi-input multi-output (MIMO) communication mode, and the second communication mode is the other of the multi-cell coordinated multi-point (CoMP) communication mode and the single-cell multi-input multi-output (MIMO) communication mode. The switching step can be performed without signaling from a base station.
