Abstract
The present invention discloses an information transmission method, a device, and a system, relates to the communications field, and resolves a problem in the prior art that in a D2D scenario, a terminal device cannot perform D2D communication due to a relatively long distance or a relatively significant change in channel quality. A specific solution is: generating, by a first device, a first scrambling sequence according to a first scrambling seed, where the first scrambling seed is generated according to a relay level or an information source of first information, scrambling the first information according to the first scrambling sequence, and sending the first information. The present invention is applied to information transmission.

An information transmission method, applied to a device to device (D2D) scenario, the method comprising:
- generating, by a first device, a first scrambling sequence according to a first scrambling seed, wherein the first scrambling seed is generated according to a relay level or an information source of first information, the relay level of the first information for indicating a quantity of relay devices that the first information has passed by before being transmitted to a receive end, and the information source of the first information for indicating a location of a starting device for transmitting the first information;
- and
- scrambling, by the first device, the first information according to the first scrambling sequence, and sending the first information.
An information transmission method, applied to a device to device (D2D) scenario, the method comprising:
- receiving, by a second device, first information when a relay level of the first information is a preset level or an information source of the first information is a preset source, the relay level of the first information is for indicating a quantity of relay devices that the first information has passed by before being transmitted to the second device, and the information source of the first information for indicating a location of a starting device for transmitting the first information;
- generating, by the second device, a first scrambling sequence according to a first scrambling seed, wherein the first scrambling seed is generated according to the relay level or information source of the first information;
- and
- descrambling, by the second device, the first information according to the first scrambling sequence.
