Abstract: In the embodiments of the present invention, a first-type terminal increases signal transmit power and/or a second-type terminal decreases signal transmit power, or when selecting a resource location for signal transmission, a terminal may exclude a resource location that is close in frequency domain to and located in a same time interval as a resource location reserved by another terminal of a different type, or resource locations used by different types of terminals to transmit signals are separated by a resource location occupied by a guard band, to reduce in-band emission interference.

Abstract: The present invention relates to the communications field, and discloses a data transmission method, a device, and a system, so as to resolve a problem in the prior art that user equipment cannot correctly parse data or measure a channel due to incapability of identifying different operators. A specific solution is: obtaining a scrambling code sequence, where the scrambling code sequence is generated according to a specific sequence of an operator to which a first device belongs; scrambling data according to the scrambling code sequence to obtain the scrambled data; and sending the scrambled data. The present invention is used for data transmission.
