METHOD FOR GENERATING, TRANSMITTING THE REFERENCE SIGNAL OF WIRELESS CHANNEL MEASUREMENT AND DEVICE THEREOF

摘要

A method for generating the reference signal of wireless channel measurement used in a multiple frequency carriers communication system is provided, a first sub-sequence and a second sub-sequence are firstly selected according to the length NSeq of the reference signal sequence, and NSeq=N1+N2, N1 is the length of the first sub-sequence, N2 is the length of the second sub-sequence, R= N1/N2, NSeq, N1, N2, R are natural numbers, said length is denoted by the signal number; the reference signal sequence is generated according to said first sub-sequence and second sub-sequence, in the i(R+1)~i(R+1)+R signals of the reference signal sequence, there are R signals to be the i·R~i·R+R-1 signals of the first sub-sequence, the rest one signal is the ith signal of the second sub-sequence, i=0, 1, ..., N2-1, and the relative position of the one signal and the R signals is fixed when i takes different values. Meanwhile a method for transmitting the above reference signal and device for generating and transmitting the reference signal are provided in the present invention. When there are some restrictive factors for the reference signal sequences, the original Peak-to-Average Ratio quality of these sequences can also be preferably reserved by the present invention.
