Abstract
Example signal transmission methods based on satellite communication and apparatus are described. One example method includes: obtaining, by a communication device, carrier attribute information corresponding to a target carrier used to transmit an orthogonal frequency division multiplexing (OFDM) symbol. The carrier attribute information of the target carrier includes subcarrier spacing. The communications device determines a cyclic prefix (CP) length of the OFDM symbol based on the carrier attribute information of the target carrier and a preset correspondence between carrier attribute information and the OFDM symbol. The CP is used to carry first data. The first data is data in the OFDM symbol.
