Disclosed are a base station backhaul method, a relevant device, and a base station backhaul system. The base station backhaul method comprises: modulating data borne by at least two channels to corresponding subcarriers respectively, combining and modulating the subcarriers into one first OFDM signal, and sending the first wideband OFDM signal to a radio remote unit, so that the radio remote unit performs splitting and filtering on the first wideband OFDM signal and sends the signal after splitting and filtering to an antenna interface; and receiving a second wideband OFDM signal sent by the radio remote unit, demodulating subcarriers included in the second wideband OFDM signal, and sending data obtained through demodulation to corresponding channels respectively. The present invention can increase a utilization rate of link channels, and achieve high-capacity base station backhaul in a low cost condition. |
