Provided are a method and device for transferring uplink data, the method comprising: a network apparatus determines, from a first mapping mode and a second mapping mode, a target mapping mode; the network apparatus transmits, to a first terminal apparatus, information indicating the target mapping mode; the network apparatus receives a first demodulation reference signal and a first data signal generated by the first terminal apparatus performing resource mapping according to the target mapping mode; in the first mapping mode, a number of subcarriers mapped by the data signal is different from that of subcarriers mapped by the demodulation reference signal, the data signal being mapped to subcarriers of an integer multiple of N, the demodulation reference signal being mapped to subcarriers with an integer multiple being 12, and N being any one of the following numerical values: 2, 3, 4 or 6; and in the second mapping mode, the number and positions of the subcarriers mapped by the data signal and the demodulation reference signal are the same, and the data signal and the demodulation reference signal are mapped to subcarriers with an integer multiple being 12. |
