Abstract: A data sending apparatus includes a processor and a transceiver. The processor is configured to generate K first frequency-domain data streams, wherein a kth first frequency-domain data stream of the K first frequency-domain data streams is determined by performing preprocessing on a kth first modulated data stream, and the preprocessing includes at least a Fourier transform, a cyclic extension, or a phase rotation. The processor is further configured to map the K first frequency-domain data streams to frequency-domain resources to generate a time-domain symbol, and the transceiver is configured to send the time-domain symbol. A length of the kth first frequency-domain data stream of the K first frequency-domain data streams is Nk, and a length of the kth first modulated data stream is Mk. K is a positive integer greater than 1, Nk and Mk are positive integers, and k is an integer k=0, 1, . . . , K−1.
