Abstract
The present application relates to the technical field of communications, and disclosed therein are a data transmission method and device, which are used to better support non-orthogonal multiple access data transmission in an uplink grant-free scenario. The data transmission method comprises: determining a demodulation reference signal (DMRS) orthogonal port pattern of an uplink data channel, there being more than 12 DMRS orthogonal ports; and using the DMRS orthogonal port pattern to carry out data transmission.
