Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the invention is described in detail.Fig. 1 is the workflow schematic diagram of system of the present invention.As shown in Figure 1, the correlative factors such as Block Error Rate of the CQI that mobile communication system reports according to UE (portable terminal), current available code channel number, outgoing data amount, power and data channel, determine that this sends the performing step of the transmission block size of using, in force as a reference whether concrete certain correlative factor, can adjust, the combination of various correlative factors can be adjusted.What list here is a kind of implementation method, specifically comprises:
At first, adjust TBsize according to code channel number, comprising:
Step S101 according to UE ability level and current C QIinit value (CQIinit is exactly the CQI value that UE reports), tables look-up in table 1 (the UE ability level attribute list selected parts that define in the 3GPP agreement) and obtains the required code channel number Cneed of CQI correspondence.Selected parts in the attribute list that this table 1 also can define from other agreement.At this moment, determined position is designated as Row1 in table;
Step S102, the size of the code channel number Cavail that required code channel number Cneed that obtains among the comparison step S101 and current system can use, (Cneed is Cavail) as actual required code channel number C to get C=Min;
