The ACK occupancy of step 32, statistical history when ACK region size is not enough, increases ACK region size, when ACK region size is idle, reduces ACK region size.
This step 32 comprises:
This slot s lot supports the number thresholding to be the subburst number that current ACK region supports;
Slot scheduling frame number FullNum is expired in step 323, increase continuously; Turn to step 325;
With the whole subchannels of 10M, the ranging cycle is that every frame is assigned as example, determines the size of ACK region below, and this process comprises:
Step 1, obtain the magnitude range [0,29] of ACK Region;
Step 2, suppose that InitACK is 1, as enabling HARQ user when entering, if the current HARQ of enabling number of users is 1, directly adjusting CurrACKNum is 2, and more users and CurrACKNum less than 3 are adjusted into 3;
Step 3, adjust feedback areas by full slot scheduling rising thresholding and measurement period and respectively lift one for example down, establishing CurrACKNum is 4:
A) (establishing FullNum is 19, and FullUpthro is 20, and FullUpStep is 1) previous frame scheduling burst number is 8, and the rising thresholding has been satisfied in full slot scheduling at present, and then increasing CurrACKNum is 5;
B) (establishing StatPeriod is 200, UpThro is (CurrACKNum-0.5)/CurrACKNum, DownThro is (CurrACKNum-1.5)/CurrACKNum, and UpStep and DownStep are 1), if the current measurement period that arrived, and TransNum is 1400～1499, then＞and UpThro, increase CurrACKNum to 5, if TransNum is＜1000, then＜and Downthro, then reduce CurrACKNum to 3.
