Embodiment Construction
[0048] Due to the complexity of the wireless channel and the diversity of channel coding methods, there is a certain error between the obtained average MI and the equivalent MI of the AWGN channel. In the prior art solution, the error is usually corrected by using a fixed correction value obtained by simulation. However, in some extreme cases, using a fixed correction value to correct the average MI still has a large error, which cannot meet the decoding requirement of 10% BLER, so that the transmission capacity of the wireless channel cannot be utilized to the maximum extent, resulting in the throughput of the LTE system. amount of loss.
[0049] In the embodiment of the present invention, the CRC statistics are performed on the decoding results of the data blocks transmitted by the PDSCH, and the average MI is correspondingly corrected according to the results of the CRC statistics, and the corresponding CQI information is selected by using the corrected average MI, and the ...
