Abstract: The present application provides a data transmission method and a related device. In the data transmission method, a sending end can perform differential encoding on original data on at least two continuous resources to obtain data to be sent, so as to map the data to be sent to the at least two continuous resources for sending; accordingly, a receiving end can receive the data on the at least two continuous resources, and perform differential decoding on the data on the at least two continuous resources to obtain the original data. Hence, the data transmission method no longer relies on DMRS-based channel estimation, and thus can avoid the problem that excessive DMRS overhead limits the improvement of system spectrum efficiency, and the problem of large performance loss due to the inaccuracy of DMRS channel estimation in a high-speed movement or high delay scene. Therefore, the present application facilitates further improving the spectrum efficiency, and controlling the performance loss of data demodulation in the high-speed movement or high delay scene to be relatively small.
