Disclosed in an embodiment of the present invention are a data demodulation method, device and system, the method comprising: transmitting the same cyclic shift (CS) hop information to a user equipment (UE), the CS hop information being used to instruct the UE to close a group hop and/or a sequence hop, and instruct the UE to generate a CS hop solution used by a reference signal (RS); receiving the RS transmitted by the UE, estimating wireless channel fade according to the RS, and demodulating out data information according to the estimated value of the wireless channel fade. The method, device and system in the embodiment of the present invention enable the uplink RSs transmitted by different UEs to be orthogonal to each other, and can further improve data demodulation performance. |
