Abstract

Embodiments of the present disclosure disclose an information transmission method and apparatus and relate to the field of communications technologies, which can initialize a sequence generator during device-to-device communication, reduce time of transmitting data between a transmitter and a receiver, and save transmission resources. The method of the present disclosure includes: initializing, by a transmitter, a sequence generator according to a synchronization source ID, a group ID, and a timeslot number, scrambling to-be-transmitted information according to a pseudo random binary sequence generated by the sequence generator, and transmitting scrambled to-be-transmitted information; and receiving, by a receiver, the scrambled to-be-transmitted information transmitted by the transmitter, and descrambling the scrambled to-be-transmitted information transmitted by the transmitter. The present disclosure is applied to a scenario in which a transmitter scrambles and transmits to-be-transmitted information.
