Provided are a multi-antenna implementation method, device and system. In a multi-antenna system, frequency conversion of different frequency points is performed via an LMU on signals within a plurality of antenna channel signals outputted by a base station except for one signal, and the signals which have undergone frequency conversion and the signal which has not undergone frequency conversion are sent to a UE and RMBs after being combined, the RMBs restoring the signals which have undergone frequency conversion to the original frequency points and sending the signals to the UE, so that the UE simultaneously receives the signal within the combined signals which has not undergone frequency conversion and the restored signals sent by the RMBs. The UE can thus simultaneously receive a plurality of signals without the number of antennae being increased. Therefore, multi-antenna technology can be implemented without increasing antenna deployment, and system performance can be improved without increasing costs. |
