Problems solved by technology
[0002] In the prior art, in order to detect and determine the interference from the base station, the sounding sequence is designed, such as the GCL sequence with ideal periodic autocorrelation characteristics, excellent cross-correlation characteristics and low peak-to-average power ratio characteristics; however, the sounding sequence can only It is used for detection, such as realizing the synchronous detection function by judging whether the peak value exceeds the threshold, but it does not have the function of carrying information. If information needs to be transmitted during the detection process (such as the latitude and longitude of the base station, etc.), it must be obtained through other means. Additional transmission of this information, such as using the existing QPSK modulation method to carry information through phase, etc.

Embodiment Construction
[0032] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0033] figure 1 It is a schematic flowchart of a method for transmitting information according to an embodiment of the present invention.
[0034] Wherein, the method of this embodiment is mainly realized through the transmitting end and the receiving end; wherein, the transmitting end includes any device having a transmitting function in the communication system, such as a base station, user equipment (such as a tablet computer, a smart phone, a PDA, etc.) ), etc.; the receiving end includes any device capable of receiving functions in the communication system, such as a base station, user equipment, etc.; preferably, the communication system is an LTE system, and more preferably, the communication system is an LTE TDD system.
[0035] It should be noted that the transmitting end, receiving end, and communication system are only examples, and other existing...

The invention provides an information transmission method. A transmitting end implements the following operations: a. on the basis of to-be-transmitted information, conducting cyclic shift on an initial sequence, superposing the initial sequence and all the sequences obtained after the cyclic shift, and generating a final sequence which needs to be transmitted to a receiving end; b. transmitting the final sequence to the receiving end. The receiving end implements the following operations: A. receiving the final sequence from the transmitting end; B. relating the final sequence and the initial sequence, acquiring the information carried in the final sequence. According to the invention, the method can represent information through the position of a peak value of the sequence.
