1. A method, wherein the method comprises:
generating, by a first communication apparatus, a first signal, wherein a symbol comprised in the first signal is carried on K+2(M−1) subcarriers, and the K+2(M−1) subcarriers are shaped using a time domain pulse that satisfies following: a width of each of some or all side lobes of a spectrum of the time domain pulse is equal to 1/M of a main lobe width, a subcarrier spacing between adjacent subcarriers is 1/M of the main lobe width, starting M−1 subcarriers and last M−1 subcarriers in the K+2(M−1) subcarriers are redundant subcarriers, K is a positive integer, and M is a positive integer greater than 1; and
sending, by the first communication apparatus, the first signal.
