Below by way of concrete example, illustrate the essence of the technical scheme of the embodiment of the present invention further.
In the embodiment of the present invention, the direct regulating object associated is indicated to be defined as the signal to noise ratio after demodulation (SNR, Signal-to-Noise Ratio) estimated value by with channel quality;
The adjusting range of SNR estimated value and smallest particles degree, all can meticulous setting and adjustment;
SNR adjustment process comprises two stages: coarse regulation stage and essence adjusting stage;
Reported the mapping relations of value by SNR estimated value and CQI, achieve the intense adjustment of CQI, ensure that the channel quality indication (CQI) information that link adaptation techniques relies on is more timely and accurate.
The embodiment of the present invention is for WCDMA and TD-SCDMA system, and as shown in Figure 2, the method for adjustment of the channel quality indication (CQI) information of the embodiment of the present invention mainly comprises two adjusting stages:
The SNR coarse regulation stage: by high speed descending sharing channel (HS-DSCH, High SpeedDownlink Shared Channel) obtain the first Block Error Rate (BLER passing new data, Block Error Rate) when being greater than certain performance threshold preset (this thresholding is set by carrier network), SNR estimated value needs the coarse regulation carrying out large step-length, within converging to rapidly to make BLER value the performance threshold preset, enter the SNR essence adjusting stage;
The SNR essence adjusting stage: the correct reception result (ACK passing new data according to HS-DSCH head, and garbled-reception result (NACK Acknowledge), Non-Acknowledge) distribution situation, real-time update is carried out to BLER value, and determines that signal to noise ratio as " SNR-to-CQI " mapping table inquiry entrance is the need of adjustment and corresponding adjustment direction and step-length according to BLER value.
Suppose that the signal-to-noise ratio (SNR) estimation value after HS-DSCH channel demodulation is SNR
est, be SNR as the signal to noise ratio of " SNR-to-CQI " mapping table inquiry entrance
map, the inquiry Output rusults of " SNR-to-CQI " mapping table is that CQI reports value CQI
rep, then the correlated process of SNR coarse regulation stage and essence adjusting stage specifically describes as follows:
The SNR coarse regulation stage comprises the following steps:

sNRthe value of adjustment step-length; Specifically comprise the following steps:
Step 1: suppose that the SNR coarse regulation stage obtains, the BLER value converged within the performance threshold that presets is BLER
ini, as the initial value of SNR essence adjusting stage BLER refresh operation; BLER refresh operation adopts infinite impulse response (IIR, Infinite Impulse Response) filter (being not limited thereto in the embodiment of the present invention) to realize, and filtering factor is alpha
bLER, span is [0,1], and the weight shared by ACK/NACK value of the HS-DSCH head biography data of current acquisition is (1-alpha
bLER); The output of iir filter is BLER_CUR;
Step 2: suppose SNR
