16. device as claimed in claim 15 is characterized in that, when outgoing data was the BCCH channel of broadcast control data, described selection module was determined to select TBSize, specifically comprises:
According to CQI, available DSCH code channel number and UE ability rating, tentatively determine TBSize;
Determine maximum available TBSize, when tentatively determining TBSize, reduce TBSize,, determine TBSize once more, otherwise need not reduce TBSize up to being less than or equal to maximum available TBSize greater than the available TBSize of maximum;
The packet header that the above-mentioned PDU that determines that once more TBSize strengthens than layer two wraps is big; With
When above-mentioned TBSize is not more than current data to be sent, determines that above-mentioned transmission block is the last selection TBSize that determines, otherwise must reduce TBSize, be not more than current data to be sent up to TBSize.
17. device as claimed in claim 15 is characterized in that, when outgoing data was non-BCCH channel of broadcast control data, described selection module was determined to select TBSize, specifically comprises:
According to CQI, available DSCH code channel number and UE ability rating, tentatively determine TBSize;
Judge preliminary TBSize of determining and outgoing data, if determine that tentatively TBSize is bigger than outgoing data, then further dwindles TBSize, method is: according to available DSCH code channel number and code check, compare with outgoing data, progressively reduce the scope, up to TBSize less than outgoing data; If determine that tentatively TBSize is littler than outgoing data, determine tentatively that then TBSize is exactly the selection TBSize that will determine.
18. the dispensing device of a transmission block is characterized in that, comprising: distribution module, computing module is selected module, logging modle, sending module,
Described distribution module is used to distribute available HS-SCCH channel, and the DSCH code channel number can be used in the sub-district, and idle HARQ;
Described computing module, HS-SCCH power demand and HS-PDSCH power demand when being used to calculate this scheduling;
Described selection module is used for according to CQI, available DSCH code channel number, UE ability rating, and outgoing data, determines to select TBSize;
Described sending module is used for selecting TBSize in the transmission of eating dishes without rice or wine with determining.
19. device as claimed in claim 18 is characterized in that, described device also comprises logging modle, is used for DSCH code channel number, modulation system, TBSize, broadcast transmitted sequence number TSN are recorded in the scheduling pattern.
