Abstract
Embodiments of this application provide a non-coherent data transmission method and a communication apparatus. In the method, a transmit end device determines, in a first constellation, a first constellation point corresponding to first to-be-modulated bits, where the first constellation point corresponds to P first symbols, P=M*N, M is a positive integer, and N is an integer greater than 1; and sends the P first symbols on N resource units by using M antenna ports, or sends P second symbols determined based on the P first symbols, and foregoes sending demodulation reference signals of the P first symbols or the P second symbols. In the method, a constellation is designed, and each constellation point in the constellation corresponds to a plurality of resource units so that data can be transmitted with no need to transmit a reference signal, and only the data needs to be transmitted.
