Abstract
This application provides a transmission method and a transmission apparatus, so that a receive end can correctly demodulate data. A transmission method may include performing a phase compensation operation of a corresponding frequency value on each of m first signals in k signals, to obtain m second signals, where each of the m first signals is located at a non-center frequency of a current carrier, each first signal is a synchronization signal or data, m and k each are a positive integer, and m≤k. The method may also include performing sending processing on the m second signals.
