[0066] Image 6 A flow chart of a method for wireless parameter configuration and signal transmission provided for this embodiment, the method includes:
[0067] Step 601: The transmitting station configures the subcarrier spacing, sampling frequency, and number of FFT points;
[0068] In this embodiment, the subcarrier interval Δf of the transmitting station is set to the subcarrier interval Δf of the LTE mobile communication system 1 Preferably, it can be configured as an n-th power multiple of 2, and n is an integer greater than 0; the specific configuration can be as follows: When Δf 1 =15kHz, configure n=4, that is, the subcarrier spacing of the transmitting station is Δf=2 4 *15kHz=240kHz.
[0069] Step 602: The sending station configures the number of available subcarriers.
[0070] In this embodiment, the transmitting station uses a fixed configuration mode, a dynamic configuration mode, or a semi-static configuration mode to configure the number of available...

[0073] The process of a method for wireless parameter configuration and signal transmission provided in this embodiment is as follows:
[0074] Step 601A, the transmitting station configures the subcarrier spacing, sampling frequency and the number of FFT points;
[0075] In this embodiment, the sampling frequency f of the sending station c It is configured as an integer multiple of the sampling frequency of the WCDMA mobile communication system, preferably a multiple of the k power of 2, where k is an integer greater than 0; the specific configuration can be as follows: When the sampling frequency of the WCDMA mobile communication system is 3.84MHz, configure k= 3. The sampling frequency f of the sending station c =3.84MHz*2 3 = 30.72MHz.
[0076] Step 602A: The sending station configures the number of available subcarriers;
[0077] Preferably, the transmitting station uses a fixed configuration mode, a dynamic configuration mode or a semi-static configuration mode...
