Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, describe the present invention below in conjunction with the accompanying drawings and the specific embodiments.
Design philosophy of the present invention is: after UE received transmission block, measure channel quality produced the transmission block size of recommending according to the channel quality that measures; And, produce the modulation format of recommending according to the transmission block size and the current code channel resource that takies of the recommendation that produces.The solution of the present invention is applicable to but is not limited to TD SDMA (Time Division Synchronous CDMA is TD-SCDMA) in the system.
Please refer to Fig. 1, this figure is the production method flow chart of the transmission block size of recommendation during the described high speed downlink packet of the embodiment of the invention inserts, and its main implementation procedure is as follows:
After step 101, UE receive transmission block, measure channel quality;
After UE receives transmission block, current channel quality is measured, and preserved channel quality measurements.Channel quality can be represented with signal to noise ratio, amplitude and noise ratio or RSCP.All be that example describes in the embodiment of the invention, and suppose that the current signal to noise ratio that measures is 16dB with the signal to noise ratio.
The difference of step 102, the current channel quality of calculating and the last channel quality that measures, whether judge described channel quality difference greater than channel quality difference threshold value, if then produce the transmission block size of recommendation by the mode of tabling look-up, otherwise, execution in step 103;
Channel quality difference threshold value can be set as the case may be, and in embodiments of the present invention, channel quality difference threshold value is set to 10dB.After supposing to receive a last transmission block, the signal to noise ratio that measures is 8dB, and then the channel quality difference is 16dB-8dB=8dB, less than channel quality difference threshold value 10dB, so execution in step 103.
After hypothesis received a last transmission block again, the signal to noise ratio that measures was 3dB, and then the channel quality difference is 16dB-3dB=13dB, greater than channel quality difference threshold value 10dB, then produces the transmission block size of recommendation by the mode of tabling look-up.Table 1 is by the correspondence table between the transmission block size of the channel quality of emulation mode foundation and recommendation.Because current channel quality measurements is 16dB, the transmission block of the recommendation of 16dB correspondence size is 13162bit in the table 1, so the transmission block size of the recommendation that lookup table mode produces is 13162bit.
| Signal to noise ratio (dB) | The transmission block size (bit) of recommending |
| 0.5-1 | 240 |
| 1-1.6 | 256 |
| 1.6-2.2 | 273 |
| … | … |
| … | … |
| … | … |
| 14.6-5.2 | 12326 |
| 15.2-17 | 13162 |
| 17-18 | 14043 |
Table 1
Whether the transmission block that step 103, judgement receive is correct, calculates correct transmission block quantity and the erroneous transmissions number of blocks that receives according to judged result;
Two variablees can be set be respectively applied for correct transmission block quantity of record and erroneous transmissions number of blocks, when the transmission block of determining to receive is correct, correct transmission block quantity be added 1, otherwise, the erroneous transmissions number of blocks is added 1.Wherein, can judge whether the transmission block that receives is correct according to the crc value of the transmission block that receives.
During greater than correct transmission block quantity threshold value, increase the transmission block size of recommending in definite described correct transmission block quantity; At definite described erroneous transmissions number of blocks during greater than erroneous transmissions number of blocks threshold value, the transmission block size that reduces to recommend.For example can correct transmission block quantity threshold value be set to 99, erroneous transmissions number of blocks threshold value is set to 9.If the erroneous transmissions number of blocks reaches 10, because it has surpassed erroneous transmissions number of blocks threshold value 9, thereby the transmission block size that reduces to recommend.If correct transmission block quantity reaches 100,, thereby increase the transmission block size of recommending because it has surpassed correct transmission block quantity threshold value 99.
Wherein, increase or reduce after the transmission block size also can from table 1, obtain, such as selecting and the last immediate value of transmission block size of recommending.Suppose that last transmission block size of recommending is 13162bit, when then needing to increase the transmission block size, choose 14043bit immediate, in the time of need reducing the transmission block size, choose 12326bit immediate with it with it.Certainly, the recruitment of transmission block and decrease also can determine that the embodiment of the invention does not limit according to other modes.
In embodiments of the present invention, in definite correct transmission block quantity and erroneous transmissions number of blocks sum greater than receiving transmission block quantity threshold value (being set to 99) such as this value, when the transmission block size of perhaps recommending changes, also further correct number of transport blocks amount and erroneous transmissions number of blocks are carried out zero clearing, to avoid correct transmission block quantity and the unconfined increase of erroneous transmissions number of blocks.
After having produced the transmission block size of recommending, the embodiment of the invention further according to the transmission block size and the current code channel resource that takies of the recommendation that produces, produces the modulation format of recommending.
Specifically, can be in advance set up the code channel resource that takies and the corresponding relation between the modulation format separation by the mode of emulation; When the transmission block sizes values of determining described recommendation is demarcated point value less than the pairing modulation format of the current code channel resource that takies, produce the modulation format QPSK that recommends; Otherwise, produce the modulation format 16QAM that recommends.The described current code channel resource that takies obtains from HS-SCCH.
Table 2 is by the code channel resource that takies of emulation mode foundation and the correspondence table between the modulation format separation.For example, if the transmission block size of recommending is 13162bit, 78 physical code channel transmission of current employing data, point value 4037bit obtains demarcating by tabling look-up.Like this, the transmission block sizes values 13126bit of the recommendation of generation is greater than described boundary point value 4037bit, so produce the modulation format 16QAM that recommends.
