Abstract
A communication method includes: determining, by a first device, a first synchronization signal, where the first synchronization signal is used by a second device for symbol timing alignment and frequency synchronization; and sending, by the first device, the first synchronization signal on each group of subcarriers of M groups of subcarriers, where M is a positive integer greater than or equal to 2. According to the communication method in this application, the first device sends the first synchronization signal on each group of subcarriers of a plurality of groups of subcarriers, so that the second device can select, based on a reception capability of the second device, an appropriate bandwidth to receive the first synchronization signal.
