Embodiment Construction

[0093] In view of the problem that in the previous application scheme, when an error occurs in the absolute amount of AMC feedback (such as ACQI information) transmitted by the receiving end, it may cause adverse effects on the specific implementation process of the AMC technology, the applicant proposes that the sending end (such as Node B) in each When the absolute amount of AMC fed back by the receiving end is received for the first time, the judgment process for judging whether the absolute amount of AMC fed back by the receiving end is correct is added, and when it is judged that the absolute amount of AMC fed back by the receiving end is wrong, the absolute amount of AMC fed back by the receiving end is judged Correction processing is performed to obtain the corrected absolute amount of AMC, so as to eliminate adverse effects on the specific implementation process of the AMC technology and make the technical solution of the prior application proposed by the applicant more ...

Abstract

The invention discloses a reliable receiving method of self adapting modulating code information that includes the emission end judges whether the self adapting modulating code absolute quantity which is corresponding with a emission antenna and feedback by the receiver is error; and under condition of error, the self adapting modulating code absolute quantity which is corresponding with a emission antenna and feedback by the receiver can be calibrated. The invention also discloses a reliable receiving device of self adapting modulating code information. The scheme of the invention can eliminates the effect of implement cause to AMC technique when transmitting AMC absolute quantity is error.

Description

technical field [0001] The present invention relates to multiple-input multiple-output (MIMO, Multi-InputMulti-Output) technology and adaptive modulation and coding (AMC, Adaptive Modulation and Coding) technology in a mobile communication system, in particular to a reliable receiving method for adaptive modulation and coding information and devices. Background technique [0002] At present, because MIMO (Multi-Input Multi-Output) technology has irreplaceable superiority of other technologies in terms of increasing system capacity and improving system performance, MIMO technology is widely used in mobile communication systems. The application in is getting more and more attention. Among them, MIMO technology mainly includes two categories, one is space diversity technology for the purpose of maximizing diversity gain, and the other is space division multiplexing technology for the purpose of maximizing data rate. [0003] Among them, the space division multiplexing technol...
