Method for base station backhaul, related device and system for base station backhaul

摘要

Embodiments of the present disclosure disclose a method for base station backhaul, a related device and a system for base station backhaul. The method for base station backhaul includes: modulating data carried on at least two channels to corresponding subcarriers respectively, combining and modulating the subcarriers to a first OFDM signal, sending a first broadband OFDM signal to a remote radio unit, sending, by the remote radio unit, the first broadband OFDM signal to an antenna port after splitting and filtering the same; receiving a second broadband OFDM signal sent by the remote radio unit, demodulating subcarriers included in the second broadband OFDM signal, and sending data obtained by demodulating to corresponding channels respectively. By adopting the present disclosure, a utilization rate of a link channel may be improved, and high-capacity base station backhaul may be achieved under a low cost condition.
