In the technical solutions according to the embodiments of the present document, supporting or not supporting the use of the M-order modulation is flexibly configured according to a signal to interference plus noise ratio condition, which supports the high-order modulation on the basis of compatibility with the existing wireless transmission network, can better realize the adaptive modulation and coding while ensuring accuracy of transmission, thereby improving the system peak rate and the spectral efficiency; and the configuration should be simplified as much as possible, thereby reducing the complexity of the table configuration.

[0203] With the technical solutions according to the above embodiments, it is possible to reasonably configure the use of the M-order modulation (herein M is greater than or equal to 256), which provides an appropriate signal to interference plus noise ratio condition for the use of the M-order modulation. This can well support the use of the M-order modulation, trade off the relationship between the improvement of the spectrum efficiency and the guarantee of the accuracy of the transmission, thereby simplifying the configuration and improving the peak data transmission rate and throughput of the wireless communication system.

[0207] The above description is only the embodiments of the present document, and it is not used to limit the present document. For those skilled in the art, the present document can have a variety of modifications and changes. Any change, equivalent replacement and improvement etc. made within the spirit and the principle of the present document should be contained within the protection scope of the present document.

INDUSTRIAL APPLICABILITY

[0208] In the above technical solutions provided by the present document, a technical measure of the base station selecting a MCS table according to a transmission type and predefined information and transmitting I.sub.MCS based on the MCS table selected by the base station is used to solve the technical problem that the conventional table cannot support a higher-order modulation, thereby achieving the transmission between the base station and the terminal based on the higher-order modulation.
