Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art Every other embodiment obtained without making creative work, shall fall within the protection scope of the present invention.
In the prior art, the TBS value that can be used when PUSCH transmission data is referring to table 1:
Table 1
In table 1, NPRBIndicate RB number, ITBSIndicate TBS index, ITBSValue can be determined by table 2.
Table 2
In table 2, IMCSIt is modulation coding scheme (Modulation and Coding Scheme, MCS) index, rvidxGeneration Table PUSCH data used redundancy versions, Q ' when transmittingmRepresent modulation system, Q 'mExpression QPSK modulation system when equal to 2,4 16 quadrature amplitude modulations (Quadrature Amplitude Modulation, QAM) modulation system and 64QAM are respectively represented with 6 Modulation system.
In the prior art, base station includes MCS index I in uplink scheduling order (UL grant)MCS, and choose RB several NPRBEtc. information, thus the transmission of dispatching uplink data.Base station can also configure UE and be carried out by the way of TTI binding The data of PUSCH are transmitted.In the prior art, the application of TTI binding scheme can only be limited in RB number less than or equal to 3, and QPSK The case where modulation system.So, under the restrictive condition, the TBS value that when TTI binding can use is exactly corresponding NPRBFor 1-3 and ITBSFor the value of 0-10, as it can be seen from table 1 the maximum value of TBS value is 504 at this time.
As described in the background art, for the TTI binding scene of 4 continuous subframes of binding, TBS value can not at 504 Meet the requirement of data rate in PUSCH.
In order to meet the requirement of data rate in PUSCH, by taking data rate in PUSCH is 384kbps as an example, when using 4 When a TTI binding and Block Error Rate (Block Error Rate, BLER) are 10%, TBS needs at least are as follows: 384 × 4/90%= 1707。
In conjunction with table 1, the value with 1707 immediate setting numbers can be chosen, such as be selected as 1736 or 1800.
That is, to meet the coverage requirement of data rate in PUSCH in the embodiment of the present invention, need full simultaneously Foot: RB is smaller, larger using QPSK modulation system and TBS value.Wherein, the smaller number for referring to RB of RB is less than or equal to specific Value, particular value, which is, for example, that 8, TBS value is larger, refers to that TBS value can meet data rate in PUSCH in TTI binding transmission mode It is required that is, TBS value is at least are as follows: (data rate in PUSCH) × (number of the TTI of binding)/(1-BLER), such as range is A value and the value already present value in existing table (table 1), such as 1736 or 1800 between [568,2152].Implement below In example for simplicity, that RB number is known as RB less than or equal to particular value is smaller, will meet in TTI binding It is larger to be known as TBS value for the TBS value of data rate requirement in PUSCH.
But from table 1 it can also be seen that corresponding modulation system is no longer just when TBS value is 1736 or 1800 QPSK and/or corresponding RB number are also no longer smaller, for example, ITBS=14, NPRBCorresponding TBS is 1736 when=6, still, at this time Modulation system be 16QAM.
In order to meet above-mentioned condition simultaneously in the embodiment of the present invention: RB is smaller, using QPSK modulation system and TBS value compared with Greatly, it can modify to table 1, using modified table as the second table.May include:
In one: the second table of mode, it is less than or equal to particular value in RB number and the corresponding modulation system of TBS index is Corresponding TBS value when QPSK is repaired to RB number identical in the first table and the corresponding TBS value of identical TBS index It is obtained after changing, so that modified TBS value can satisfy rate requirement required when TTI binding transmission.
For example, original ITBS=8, NPRB=3 corresponding TBS values are 392, and by I in the embodiment of the present inventionTBS=8, NPRB= 3 corresponding TBS values are changed to 1736.In two: the second table of mode, it is less than or equal to particular value and TBS value energy in RB number Corresponding TBS index corresponding modulation system when required rate requirement, is in the first table when enough meeting TTI binding transmission What identical RB number and the corresponding modulation system of the corresponding TBS index of identical TBS value obtained after modifying, the modification for being Modulation system afterwards is QPSK.
For example, original NPRB=3, TBS=1736 corresponds to ITBS=23, and ITBSModulation system when=23 is 64QAM, and By I in the embodiment of the present inventionTBSModulation system when=23 is changed to QPSK.
In three: the second table of mode, it can satisfy TTI in the corresponding modulation system of TBS index for QPSK and TBS value and tie up Corresponding RB number is greater than RB that the first table can be selected when TTI binding is transmitted when required rate requirement when transmitting surely Several maximum values;
For example, in the prior art, the maximum value for the RB number that the first table can be selected when TTI binding is transmitted is 3, and RB can choose number can be expanded in the embodiment of the present invention, for example, 8 are expanded to, then according to the first table (table 1), When the RB number that can be selected is less than or equal to 8, above-mentioned rate required when meeting TTI binding transmission can also be found and wanted The TBS value and corresponding modulating mode asked are QPSK.
Specifically, the present invention provides following examples.
Fig. 1 is the flow diagram of one embodiment of data transmission method of the present invention, comprising:
Step 11:UE selects TBS value according to preconfigured second table, and second table is for describing TBS value, RB Corresponding relationship between number, TBS index, the corresponding RB number of selected TBS value are less than or equal to particular value, the choosing The corresponding modulation system of the corresponding TBS index of the TBS value selected is QPSK, and the selected TBS value can satisfy TTI binding biography Required rate requirement when defeated;
Step 12:UE is according to the selected TBS using the data of the TTI transmission PUSCH carrying of binding.
Wherein, in the embodiment of the present invention, by existing table, i.e. table 1 is known as the first table, and will be new in the embodiment of the present invention The table of proposition is known as the second table, and the first table and the second table can be pre-configured in UE.
In addition, the upstream data of UE is dispatched by base station, that is, can also include: UE reception base station before step 11 The configuration information of transmission, the configuration information are used to indicate the data of the TTI transmission PUSCH carrying using binding;And UE is received The scheduling information that base station is sent, the number of index and RB in the scheduling information including MCS.
It, can (table 2 can be pre-configured with according to the index and table 2 of MCS wherein included after UE receives scheduling information In UE) search obtain the index I of corresponding TBSTBS, later further according to ITBS, RB number NPRBWith the second table (existing skill Art is according to table 1) search obtain the value of TBS.Later can be according to the value of the TBS found, and the configuration information received, Using the data of the TTI transmission PUSCH carrying of binding.In the prior art only have the first table, no matter therefore TTI whether bind all Using the first table, still, as stated in the background art, according to existing first table, when TTI binding, it is less than or equal to 3 in RB And the TBS under QPSK modulation system, i.e. N in table 1PRBFor 1-3 and ITBSIt is not to be able to satisfy number in PUSCH for the corresponding TBS of 0-10 According to the rate requirement of rate.For this purpose, newly propose second table in the embodiment of the present invention, in TTI binding using this Two tables, TBS corresponding to and QPSK modulation system smaller in RB is larger to meet data rate in PUSCH in second table It is required that.
It is smaller, larger using QPSK modulation system and TBS that second table meets RB simultaneously, can thus use TTI The mode of binding transmits business datum when data rate in PUSCH.
The present embodiment proposes the second table as above, which shows that the value of TBS therein is larger, TBS is corresponding RB is smaller and the corresponding modulation system of TBS is that QPSK since the value of TBS is larger can satisfy the requirement of PUSCH medium-rate, And bigger Turbo coding gain can be obtained and reduce expense, using the available preferable MCL of lesser RB and QPSK Value, therefore, coverage area when data rate in PUSCH can be improved using aforesaid way.
Further, in data of the TBS selected according to the second table using the TTI transmission PUSCH carrying of binding, such as Fruit can there are problems that losing more information bit according to existing transmission mode.It is existing for binding continuous 4 subframes There is technology when transmitting data using TTI binding mode, 4 redundancy versions after a transmission block coding are respectively mapped to connect In 4 continuous TTI, this 4 redundant version numbers can be 0,2,3,1.Information bit needs after carrying out Turbo 1/3 and encoding Rate-matched is carried out according to available resource size, selected data exist when what redundant version number indicated is rate-matched Initial position after Turbo 1/3 is encoded in obtained data.But transmission mode may cause information bit loss in this way.
For example, with reference to Fig. 2, it is assumed that value=1736 TBS, corresponding RB number is 3, then can transmit in a TTI Bit number=12 (subcarrier number in each RB) × 12 (the data symbol number in each RB) × 3 (RB number) × 2 (each QPSK modulation symbol corresponding bit number)=864 bits.1736 information bits add the circulation school of 24 bits first (Cyclic Redundancy Check, CRC) is tested, then completes the volume of Turbo 1/3 after adding (1736+24) × 2 check bit Code.The data to be transmitted by the way of TTI binding include information bit and check bit, and different redundancy versions represent institute Different initial positions of the data of selection in the data after the coding of Turbo 1/3, different redundancy versions are expressed as RV0, RV1, RV2 and RV3, figure it is seen that when the data that each subframe chooses 864 bits are transmitted, between subframe There can be the data that are not selected, that is to say, that some information bits are lost, such as not being selected between RV0 and RV1 Data are just lost.
In order to solve this problem, the present invention provides following one embodiment.
Fig. 3 is the flow diagram of another embodiment of data transmission method of the present invention,
Step 31: TBS is selected according to the second table.
Particular content may refer to step 11.
It can specifically include down later according to the TBS of selection using the data of the TTI transmission PUSCH carrying of binding The step 32-33 in face.
Step 32: choosing the data of PUSCH carrying, the data of the PUSCH carrying include information bit, the information ratio Special size is the selected TBS value, when choosing the data of the PUSCH carrying, in the storage position of the information bit It sets and starts to choose data in range, and the continuous information bit since choosing starting point for choosing whole.
Wherein, since the number of information bit is the TBS selected according to the second table, if according to the selection of the prior art Mode, can lost part information bit.And in the present embodiment by the way of continuously choosing information bit, due to whole from choosing The information bit for taking starting point to start all continuously is chosen, and is not in discontinuous situation, so that it may increase and indicate from RV0 The position that is indicated to RV1 of position between covering to information bit, so that it may reduce the number of information bit loss.
Optionally, it in order to guarantee continuously to choose whole information bits since choosing starting point, can continuously recycle The data that choosing the TTI bound can transmit can transmit the data instance of 864 bits with each subframe for example, with reference to Fig. 4, Under the scene of 4 subframe bindings, the present embodiment can continuously choose the data of 864 × 4 bits, the data continuously chosen, It is exactly the data of 864 × 4 bits, corresponding redundant version number can be named as RV0.
Optionally, if using the initial position of RV0 as starting point, the data for continuously choosing 2 864 bits can be covered The information bit of 1736 bits can also continuously choose 864 × 2 data referring to Fig. 5, the corresponding version of 864 × 2 data This is RV0, and the data of remaining 2 864 bits can continuously be chosen, and can also separate selection, and Fig. 5 gives what separation was chosen Signal.
Optionally, it when above-mentioned selection data, chooses in the space where starting point is located at information bit, specifically can be The position of RV0 instruction, that is, data are chosen since the position that RV0 is indicated.
Optionally, in first pass, the data transmitted since the position that RV0 indicate and continuously chosen, for example, just biography when pass The data of defeated 864 × 4 bits as shown in Figure 4, or the data of 864 × 2 bits as shown in Figure 5.
Step 33: using the data for the PUSCH carrying that the TTI transmission of binding is chosen.
For example, continuously choose 864 × 4 bits data and binding TTI be 4 when, the data of selection are divided into 4 parts, The data of every part of 864 bits are transmitted in a TTI.
The present embodiment can transmit more data using TTI binding mode in shorter time delay, reduce propagation delay time; By using biggish TBS, Turbo coding gain can be made bigger, head information and cyclic check (Cyclic Redundancy Check, CRC) expense reduction;By using RB less number, so that equivalent noise when link calculation is protected Hold reduced levels;The mapping mode for modifying TTI binding transmits more information bits;By using QPSK tune Mode processed has preferable link budget relative to 16QAM and 64QAM, so that it may obtain bigger MCL.Through the above way Coverage area when data rate in PUSCH can be improved.
