Method supporting multiple transmitting modes and base station

The invention provides a method supporting multiple transmitting modes and a base station. The method comprises the following steps: the base station configures a transmitting mode supporting dynamic switch between downlink single-user multiple-input multiple-output and downlink multi-user multiple-input and multiple-output for user equipment; and the base station selects a corresponding transmitting mode according to the received channel condition information fed back by the user equipment, and transmits data to the user equipment. According to the invention, three transmitting modes of transmitting diversity, single-user multiple-input multiple-output and multi-user multiple-input and multiple-output can be supported, and the channel condition can be sufficiently used.
