Abstract
Embodiments of the present invention provide a method for sending downlink data, a method for receiving downlink data, a base station, and a user terminal. The sending method includes modulating first downlink data into a first downlink signal by using a DFT-S-OFDM modulation mode; modulating second downlink data into a second downlink signal by using an OFDM modulation mode; and forming a downlink transmit signal from the first downlink signal and the second downlink signal in a multiplexing manner, and sending the downlink transmit signal to a user terminal. The base station includes a first generation module, a second generation module, and a first sending module. In the technical solutions of the present invention, downlink data is sent by using two modulation modes, DFT-S-OFDM and OFDM, thereby meeting requirements of different downlink data on EVM indexes.
