Disclosed are an information transmission method and device, relating to the technical field of communications. Within device to device communication, the present invention is capable of initialising a sequence generator, and reducing data transmission time between a transmitter and a receiver, thereby saving transmission resources. The method comprises: according to a synchronisation source ID, a group ID and a time slot number, a transmitter initialises a sequence generator; according to a pseudo-random code sequence produced by the sequence generator, information for transmission is scrambled; the scrambled information for transmission is transmitted; a receiver receives the scrambled information for transmission transmitted by the transmitter; the scrambled information for transmission transmitted by the transmitter is descrambled. The present invention is suitable for a scenario wherein a transmitter scrambles and transmits information for transmission. |
