Data transmission method and device

Abstract

The invention discloses a data transmission method and a data transmission device, which are used for better supporting non-orthogonal multiple access data transmission in an uplink scheduling-free scene. The data transmission method provided by the invention comprises the following steps: determining a demodulation reference signal DMRS orthogonal port pattern of an uplink data channel, the number of DMRS orthogonal ports being greater than 12; and carrying out data transmission by adopting the DMRS orthogonal port pattern.
