INFORMATION TRANSMISSION METHOD AND DEVICE

摘要

Disclosed are an information transmission method and device. The method comprises: implementing time-frequency resource mapping on first to-be-sent information and second to-be-sent information, so that a first symbol occupied by the first to-be-sent information in a sub-frame is located in front of a second symbol occupied by the second to-be-sent information in the sub-frame; adopting the OFDM technology to modulate the first to-be-sent information to obtain first modulated information, and adopting the FBMC technology to modulate the second to-be-sent information to obtain second modulated information; inserting a guard interval between the first modulated information and the second modulated information, the guard interval being used for preventing interference from being generated between the first modulated information and the second modulated information; and sequentially sending the first modulated information, the guard interval and the second modulated information to a receiving end. By means of the information transmission method and device disclosed by the present invention, interference is prevented from being generated between pilots and other information.
