For base station, base station MCS index is determined according to the CSI that terminal reports, TBS index is determined according to MCS index, and then according to the size of the TBS index and schedulable PRB number corresponding bit block size and upstream data, determine purpose than special fast size, and then the corresponding PRB number of MCS index and purpose bit block size is sent to terminal, such as, MCS index and PRB number are filled in DCI according to certain format, obtain scheduling information, pass through Physical Downlink Control Channel (Physical Downlink Control Channel, PDCCH) DCI is sent to terminal, so that terminal sends upstream data according to purpose bit block size.
For terminal, the MCS index and PRB number issued according to base station determines purpose bit block size, and then sends upstream data according to purpose bit block size and determine.Specifically, terminal is locally also preserving the first concordance list and the second concordance list, after receiving DCI, terminal parses MCS index and PRB number in DCI, and the size for sending upstream data, i.e. purpose bit block size are determined according to MCS index and PRB number.Then, upstream data is sent to base station according to purpose bit block size.In general, when channel ratio is preferable, the size of the purpose bit block size and upstream data is much the same, the even greater than size of upstream data；When bad channel, available resources are less, which is less than the size of upstream data.
Bit block size provided in an embodiment of the present invention determines that method, base station or terminal determine TBS index according to the first concordance list of MCS search index, determines purpose bit block size according to TBS index and PRB number the second concordance list of inquiry.During being somebody's turn to do, since the corresponding TBS index of MCS index each in the first concordance list increases, the corresponding bit block size of newly-increased TBS index is extended in the second concordance list, and TBS index is bigger, corresponding bit block is bigger.Correspondingly, more according to the data that the bit block is sent, it can utilize available RE in RB as far as possible.Therefore, bit block size provided in an embodiment of the present invention determines method, first concordance list is adapted to the second concordance list with uplink 256AQM, the bit block size determined according to first concordance list and the second concordance list, available RE in RB can be utilized as far as possible in upstream data transmission process, uplink code rate is promoted, reduction is lost caused by upstream peak rate, and then promotes upstream peak handling capacity and spectrum efficiency.
In the following, from the first concordance list increased first TBS index be index value be 27~34, index value is 27~35 and index value is that the present invention is described in detail for 27~36 several situations.
First, the first concordance list is to increase the MCS-TBS concordance list that index value is 27~34.
It is, for example, table 4 according to the first concordance list that agreement concordance list obtains when channel status is relatively good, terminal supports uplink 256AQM in the present embodiment.Compared to agreement concordance list, i.e. table 2, in table 4, passes through and extract the corresponding I of low order MCS indexTBS, i.e. removal index value is 1,3,5,7,9,10,19,26 TBS index, increases the high-order TBS index that index value is 27~34.In this way, work as IMCSWhen < 21, for the same MCS index, the TBS index obtained according to table 4 is greater than the TBS index obtained according to table 2, and then it is bigger according to the bit block that TBS index obtains, to which available RE in RB can be utilized as far as possible in upstream data transmission process, uplink code rate is promoted, reduction is lost caused by upstream peak rate, and then promotes upstream peak handling capacity and spectrum efficiency.Work as IMCSWhen >=21, I is extended in TBS tableTBSBit block size when being 27~34.Wherein, ITBSBit block size when being 27~33 may refer to table 3, ITBSBit block size when being 34 may refer to table 4.

The first, maximal bit block meets 256QAM peaks demand, and minimum bit block is greater than ITBS33、NPRB=1 corresponding bit block size；
The second, bit block is incremented by size between different TBS indexes or PRB, and step-length gradually increases, and keeps the padding filling rate of bit block consistent (can be converted into code rate difference and unanimously calculate data).
Specifically, with ITBS35、NPRBFor=2, due to ITBS34、NPRBWhen=1, bit block size is 1016 bits, and code rate is 0.56 (code rate calculation method 1016/ (12*12*8*1)=0.88), ITBS35、NPRBWhen=1, bit block size is 1064 bits, and code rate is 0.92, and code rate difference is 0.4, I between different TBS indexesTBS35、NPRB=2 corresponding bit blocks and ITBS34、NPRBCode rate difference between=2 corresponding bit blocks also should 0.4 or so, so, according to table 6, ITBS34、NPRB=2 corresponding bit blocks 2056 (code rate is 0.89), are greater than 1056, less than 2112, therefore, 2056 belong to 1056 grades.It is step-length with 32, successively brings 92≤i < 124 into 2056+ (i-92) × 32, until code rate reaches 0.92 (0.89+0.3), determines ITBS35、NPRB=1 corresponding bit block size is 2120.
Other data and so on.
