Provided are a wireless communication method, a user equipment, a base station and a system, relating to the field of wireless communications. The method comprises: acquiring a frequency domain spread spectrum factor, a symbol-level spread spectrum factor and a transmission time interval-level spread spectrum factor; conducting frequency domain spread spectrum, symbol-level spread spectrum and transmission time interval-level spread spectrum respectively on first information to be sent in accordance with the acquired spread spectrum factors and sending the first information to be sent; alternatively, de-spreading second spread spectrum information sent by the base station in accordance with the acquired spread spectrum factors. By acquiring the frequency domain spread spectrum factor, the symbol-level spread spectrum factor and the transmission time interval-level spread spectrum factor and sending or receiving information in accordance with the acquired spread spectrum factors, the present invention solves the problems of low transmission efficiency, longer delay time and more serious interference among various user equipments in the same frequency bandwidth when simple duplicate sending is carried out in the frequency domain or time domain in the prior art, and achieves the purpose of improving the system capacity and the resource utilization rate. |
