In the embodiments of the invention, provide the acquisition methods of mapping relations between a kind of data MCS and CQI code check, be applied to when CQI and data multiplexing situation on PUSCH.As shown in Figure 2, this method may further comprise the steps:
Step s201, whole SNR (dB) interval (from negative infinite to just infinite) is quantified as plurality of sections, hop count is the number that PUSCH goes up data MCS.
Step s202, for certain SNR value, according to the modulation system of data and transmission quality requirements (requiring) requirement, the code check that specified data is corresponding required as BLER.
Step s203, CQI adopt SNR and the modulation system identical with data, according to the transmission quality requirements (requiring as BLER) of CQI, determine the code check of CQI.Concrete, can set up the transmission quality requirements of CQI and the corresponding relation of CQI code check in advance, then can be according to the transmission quality requirements of MCS, the CQI of data and the code check that above-mentioned corresponding relation is determined CQI.
