<p>A method is provided for transmitting single carrier (SC) FDMA signal. The SC-FDMA signal includes a plurality of symbols with cyclic prefix (CP). When setting the frame length, the symbol number, the sampling rate into six manners, the terminal determines the CP sampling numbers of each symbol or the total CP sampling times of the first symbol and last symbol during up and down time. The parameters corresponding to the six manners are: 1. When frame length is 0.5ms, symbol number is 8, sampling rate is 30720 times/ms, the CP sampling times of first symbol are 156, the CP sampling times of 2nd-8th symbol are 124, the total CP sampling times of the 1st symbol and 8th symbol during up and down time are 32. 2. When frame length is 0.5ms, symbol number is 8, sampling rate is 15360times/ms, the CP sampling times of first symbol are 78, the CP sampling times of 2nd-8th symbol are 62, the total CP sampling times of the 1st symbol and 8th symbol during up and down time are 16. 3. When frame length is 0.5ms, symbol number is 7, sampling rate is 30720 times/ms, the CP sampling times of first symbol are 160, and the CP sampling times of 2nd-7th symbol are 144 the total CP sampling times of the 1st symbol and 7th symbol during up and down time are16.4. When frame length is 0.5ms, symbol number is 7, sampling rate is 15360 times/ms, the CP sampling times of first symbol are 80, the CP sampling times of 2nd-7th symbol are 72, the total CP sampling times of the 1st symbol and 8th symbol during up and down time are 8. 5. When frame length is 1ms, symbol number is 14, sampling rate is 30720 times/ms, the CP sampling times of first symbol are 176, the CP sampling times of 2nd-14th symbol are 144, the total CP sampling times of the 1st symbol and 14th symbol during up and down time are 32. 6. When frame length is 1ms, symbol number is 14, sampling rate is 15360 times/ms, the CP sampling times of first symbol are 88, the CP sampling times of 2nd-14th symbol are 72, the total CP sampling times of the 1st symbol and 8th symbol during up and down time are 16. In addition, a method is provided for setting cyclic prefix parameters in radio signal frame.</p> |
