Embodiment 1
The embodiments of the invention provide a kind of data transfer control method.Fig. 1 is the flow chart of this method, refer to Fig. 1, and this method includes：
Step 101:User equipment（UE) resource block for data transfer that base station is sent is received（RB) number and Modulation and Coding Scheme（MCS) index；
Wherein, when base station sends downlink data to UE, the RB numbers and MCS indexes that are used for data transfer refer to, the data used RB numbers and MCS indexes in the transmission；When base station scheduling UE carries out transmitting uplink data, the RB numbers and MCS indexes that are used for data transfer refer to, UE sends RB numbers and MCS Suo Gong used in data |.
Step 102:UE utilizes the MCS indexes, by inquiring about modulation and TBS index relative tables, determines transport block size（TBS) index；
Wherein, by inquiring about modulation and TBS index relative tables, it may be determined that TBS indexes.
Step 103:UE utilizes the RB numbers and the TBS indexes, and the TBS table predetermined by inquiring about determines the information bit of data transfer, and then correct coding or the decoding data. Wherein, when base station sends downlink data to UE, UE (is referred to as predetermined TBS tables by inquiring about the TBS tables of the embodiment of the present invention）, it may be determined that the number of information bit of the base station used in this data transfer, so as to be correctly decoded；When base station scheduling UE carries out transmitting uplink data, UE is by inquiring about the TBS tables of the embodiment of the present invention（Referred to as predetermined TBS tables）, it may be determined that the number of its used information bit when transmitting uplink data, so that correct coding, completes this uplink.
In the present embodiment, the predetermined TBS tables include the form of layer one, the form of layer two, the form of layer three and the form of layer four, wherein, the form of layer one includes the information bit of each available RB number of each corresponding TBS index.Wherein, the behavior TBS indexes of the predetermined TBS tables, the embodiment of the present invention continues to use 0 ~ 26 Modulation and Coding Scheme grade in standard TBS forms, totally 27 grades, for example, 1st row of the TBS tables represents that TBS indexes are the 0 corresponding element of various available RB numbers, and the 27th row represents the corresponding element of various available RB numbers that TBS indexes are 26.Wherein, the predetermined TBS tables are classified as available resource block（RB numbers）, it is assumed that can be that from 1RB to 110RB, for example, the 1st row of the TBS tables represent that available resources block number is 1 RB, the 110th row represent that available resources block number is 110 RB with RB numbers.
In this example, it is assumed that there is (4 ~ 8 layers, the concept of layer is referring to TS36.213 chapters and sections 6.3) transmission of DMRS, then the available RE numbers per RB are 12*14-12*2=144；Assuming that there is (4-8 layers of DMRS）Standing grain B CSI S (8 antenna ports) are transmitted, then the available RE numbers per RB are 12*14-12*2-8=136.Wherein, the signals such as PSS/SSS and extension CP (Cyclic Prefix, cyclic prefix are not considered）, in actual applications, when there is above-mentioned signal, encoded with the mode for the rate-matched arranged in standard TS36.212.
In the present embodiment, each element in the form of layer one in the predetermined TBS tables is determined by way of shown in Fig. 2, refer to Fig. 2, including：
Step 201:All TBS element extractions in standard TBS forms are come out, TBS element candidate sequences are generated；
In order to reduce the high-rise inconvenience in configuration information, the embodiment of the present invention is tried one's best the TBS elements reused in existing form.The TBS forms that existing form namely standard are used, in the present embodiment referred to as standard TBS forms, including the table 7.1.7.2.1-1 (forms of layer one）, the table 7.1.7.2.2-1 (forms of layer two）, the table 7.1.7.2.4-1 (forms of layer three）, the table 7.1.7.2.5-1 (forms of layer four）.
Wherein, the TBS elements candidate sequence can be arranged sequentially, for example, represented by way of two arrange, wherein, first is classified as element numbers（), index second it is classified as element value.
Step 202:Available RE numbers according to the code check and modulation system of standard TBS forms and per RB, meter The information bit number containing CRC bits for corresponding to each TBS index and each available RB number is calculated, the form rough draft of first layer one is generated；
Wherein, by RB numbers（1 ~ 110) with per RB available RE numbers（144 or 136), modulation system（2 (QPSK) or 4 (16QAM) or 6 (64QAM)) and current Modulation and Coding Scheme grade（0 ~ code check 26) is multiplied, and is rounded in the way of rounding up, it may be determined that the information bit number containing CRC bits, generates one
27*110 form, referred to as the form rough draft of first layer one.
Wherein, the behavior TBS indexes of the form, are classified as available resource block（RB) number.
Step 203:Remove the CRC bits in the information bit in the form rough draft of first layer one, generate the form rough draft of the second layer one；
Wherein, because element contained in standard TBS forms does not include CRC bits, in order to reuse the element in standard TBS forms as far as possible, the present embodiment also removes the CRC bits in the information bit of each element in form.
Wherein it is possible to according to the method that CRC bits are added in TS 36.212, inversely remove the CRC bits in the information bit in the form rough draft of first layer one, thus obtain another 27*110 form, referred to as the form rough draft of the second layer one.
Wherein, the behavior TBS indexes of the form, are classified as available resource block（RB) number.
Step 204:Each element in the form rough draft of the second layer one is traveled through, the selection element minimum with the poor absolute value of each element, the element of selection is filled out the position of each element, the form of generation layer one from the TBS elements candidate sequence.
Wherein, by taking the object element A in the form rough draft of the second layer one as an example, the selection element minimum with the poor absolute value of elements A, as the respective element of elements A, fills out A position in the TBS element candidate sequences extracted from step 201.By carrying out this processing to each element in the form rough draft of the second layer one, the form of layer one is obtained.
Likewise, the behavior TBS indexes of the form of this layer one, the form of this layer one is classified as available resource block（RB) number.In one embodiment, if there is the poor absolute value of two elements and an element in the form rough draft of the second layer one minimum in the TBS elements candidate sequence, then according to the corresponding code check of described two elements, the less element of poor absolute value for the target bit rate that selection is expert at one element is as the element described in the form of layer one on the position of an element.
For example, in the TBS elements candidate sequence, the member of the poor absolute value minimum with aforementioned elements A have two, and respectively B and C are (that is, the poor absolute value of B and C respectively with A is minimum and identical）, then this implementation Example passes through calculating elements B and the code check of Elements C, to compare the poor absolute value for the target bit rate that the element B and the corresponding code check of Elements C are expert at elements A respectively, select the less element of poor absolute value as the respective element of elements A, fill out the position of elements A.
Wherein, the method for calculating the code check of each element is same as the prior art, wherein it is desired to which CRC bits are calculated as into information bit, will not be repeated here.
In one embodiment, if last column of the form of the layer one（27th row, namely TBS indexes then select the element of element numbers smaller than the element numbers of the element one to be used as the element on the position in element 26), to have code check to be more than the element of predetermined code check threshold value from the TBS elements candidate sequence.
Wherein, the present embodiment can preset a code check threshold value, for example, 0.93.In order to avoid last column of the form of layer one（ITBSThe code check of=element 27) is more than code check threshold value, the present embodiment by preceding method after each element of the form of layer one is determined, also to calculate the code check of each element of the last column, if the code check of certain element is more than foregoing code check threshold value, namely 0.93, then select the element of element numbers smaller than the element numbers of the element one to be used as the element on the position from TBS element candidate sequences.
For example, by the code check for each element for calculating last column, it was found that the corresponding code checks of element D are more than 0.93, and serial number ds of the element D in TBS element candidate sequences, then select the element of serial number d-1 in TBS element candidate sequences to be used as the element on element D relevant position.
Wherein, the method for calculating the code check of each element is same as the prior art, wherein it is desired to which CRC bits are calculated as into information bit, will not be repeated here.
In one embodiment, in order to be consistent with former form, namely the 7th element of first row is caused（ITBSThe element of serial number 6）For 328, also the element of the form of layer one is adjusted.Wherein, if each resource block（RB available resources number) is 144 resource particles（RE), then by the 1st row of the form of layer one（For the 7th element 1) 328 can be changed to RB numbers;If each resource block（RB available resources number) is 136 resource particles (RE), then by the 1st row of the form of layer one（For the 3-7 order of elements 1) the 2-6 element of the row can be substituted with RB numbers, and the 7th element of the row is changed to 328.
In one embodiment, the form of generation is likely to occur situations below, that is, in the same row of the form of layer one, different TBS indexes（ITBS) correspondence identical element, in order to increase the flexibility of scheduling, it is to avoid such case occurs, and also the element of the form of layer one is adjusted.Wherein, in addition to numerical value is 328 element in first row, for each row of the form of layer one, travel through each element in same row, if TBS indexes are different but two elements of numerical value identical, then by the wherein less element of TBS indexes with the candidate sequence smaller than the element numbers one element Instead of.Reexamine in the row and whether also have TBS indexes different but two elements of numerical value identical, repeat the above steps, until each corresponding different element of TBS indexes in the row.
Pass through the method for the present embodiment, it may be determined that suitable for the form of layer one of the TBS tables of new carrier type.Following table is the new TBS tables that are made by embodiment of the present invention when every RB available resources number is 144 RE.
