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.
Claims22
A data transmission method, comprising:
- obtaining, by a first device, a scrambling code sequence, wherein the scrambling code sequence is generated according to a specific sequence of an operator to which the first device belongs;
- scrambling, by the first device, data according to the scrambling code sequence;
- and
- sending, by the first device, the scrambled data.
9-30. (canceled)
A first device, comprising,
- a processor;
- a memory;
- a bus;
- and
- a transmitter;
- wherein the processor, the memory, and the transmitter are connected to each other via the bus;
- wherein the processor is configured to obtain a scrambling code sequence, and scramble data according to the scrambling code sequence, wherein the scrambling code sequence is generated according to a specific sequence of an operator to which the first device belongs;
- and
- wherein the transmitter is configured to send the data scrambled by the processor.
A second device, comprising:
- a processor;
- a memory;
- a bus;
- and
- a receiver;
- wherein the processor, the memory, and the receiver are connected to each other via the bus;
- wherein the processor is configured to obtain a scrambling code sequence, wherein the scrambling code sequence is generated according to a specific sequence of an operator to which the second device belongs;
- wherein the receiver is configured to receive scrambled data;
- and
- wherein the processor is further configured to demodulate, according to the obtained scrambling code sequence, the scrambled data received by the receiver.
