In 31 3 tables 2, MCS is modulation coding mode（Modulation and Coding Scheme, MCS) index, rv_ldxRepresent the redundancy versions used during PUSCH data transfers, represent modulation system, QPSK modulation systems are represented during equal to 2,4 and 6 represent 16 quadrature amplitude modulations (Quadrature Amplitude Modulation, QAM) modulation system and 64QAM modulation systems respectively.

In the prior art, base station is in uplink scheduling order（UL grant) in include MCS indexes and choose RB numbers w_PRBEtc. information, so that the transmission of dispatching uplink data.Base station can also configure the data transfer that UE carries out PUSCH by the way of Τ bindings.In the prior art, the application of TTI binding schemes can only be limited in RB numbers less than or equal to 3, and the situation of QPSK modulation systems.So, under the restrictive condition, the TBS values that Τ can be used when binding are exactly correspondence w_PRBFor 13 and the/value that is 0 10, as it can be seen from table 1 now the maximum of TBS values is 504.

As described in the background art, scene is bound for the Τ of 4 continuous subframes of binding, TBS values can not meet the requirement of data rate in PUSCH at 504.

In order to meet the requirement of data rate in PUSCH, so that data rate in PUSCH is 384kbps as an example, when using 4 TTI bindings and Block Error Rate（Block Error Rate, BLER) be 10% when, TBS need be at least： 384 x 4/90%= 1707.

In conjunction with table 1, the value with 1707 immediate setting numbers can be chosen, for example, elects 1736 or 1800 as.

That is, the coverage that data rate in PUSCH is met in the embodiment of the present invention will Ask, it is necessary to while meet：RB is smaller, larger using QPSK modulation systems and TBS values.Wherein, the smaller numbers for referring to RB of RB are less than or equal to particular value, and particular value, which is, for example, that 8, TBS values are larger, refers to that TBS values can meet data rate requirement in PUSCH when Τ binds transmission means, i.e. TBS values are at least：（Data rate in PUSCH）X (the Τ of binding numbers）/ (1-BLER), such as scope are the value and the value between [568,2152] in existing form（Table 1) in already present value, such as 1736 or 1800.In example below for simplicity, RB numbers are referred to as to RB is smaller less than or equal to particular value, being possible to meet the TBS values of data rate requirement in PUSCH when Τ is bound, to be referred to as TBS values larger.

But, from table 1 it can also be seen that when TBS values are 1736 or 1800, its corresponding modulation system is no longer just that QPSK and/or correspondence RB numbers are also no longer smaller, for example ,/_ras = 14 , N_vCorresponding TBS is 1736 when=6, still, and modulation system now is 16 QAM.

In order to while meeting above-mentioned condition in the embodiment of the present invention：RB is smaller, larger using QPSK modulation systems and TBS values, table 1 can be modified, regard amended form as the second form.It can include：

Mode one：In second form, the corresponding TBS values when RB numbers are less than or equal to particular value and the corresponding modulation system of TBS indexes is QPSK, obtained after being modified to identical RB numbers in the first form and the corresponding TBS values of identical TBS indexes so that amended TBS values disclosure satisfy that rate requirement required during Τ binding transmission.

For example, original/_ras=8, w_PRB=3 corresponding TBS values are 392, and incited somebody to action in the embodiment of the present invention/_TBS =8, w_PRB=3 corresponding TBS values are changed to 1736.Mode two：In second form, the corresponding modulation system of corresponding TBS indexes when RB numbers are less than or equal to rate requirement required when particular value and TBS values disclosure satisfy that Τ bindings are transmitted, obtained after being modified to identical RB numbers in the first form and the corresponding modulation system of the corresponding TBS indexes of identical TBS values, the amended modulation system for being is QPSK：.

For example, original w_PRB=3, the correspondence of TBS=1736/_ras=23, and/_rasModulation system when=23 is 64QAM, and incited somebody to action in the embodiment of the present invention/_rasModulation system when=23 is changed to QPSK：.

Mode three：In second form, corresponding RB numbers are more than the maximum of RB numbers that the first form can be selected when Τ binds and transmitted during rate requirement needed for when the corresponding modulation system of TBS indexes disclosure satisfy that Τ binding transmission for QPSK and TBS values；

For example, in the prior art, the RB numbers that the first form can be selected when Τ binds and transmitted Maximum be 3, and the RB numbers that can be selected can be expanded in the embodiment of the present invention, for example, being expanded to 8, then according to the first form（Table 1), when the RB numbers that can be selected are less than or equal to 8, the above-mentioned TBS values for meeting rate requirement required during Τ binding transmission can also be found and corresponding modulating mode is QPSK：.

Specifically, the present invention provides following examples.

Fig. 1 is the schematic flow sheet of the embodiment of data transmission method one of the present invention, including：

Step 11:UE selects TBS values according to the second form being pre-configured with, second form is used to describe the corresponding relation between TBS values, RB numbers, TBS indexes, the corresponding RB numbers of TBS values of the selection are less than or equal to particular value, the corresponding modulation system of the corresponding TBS indexes of TBS values of the selection is QPSK, and the TBS values of the selection disclosure satisfy that rate requirement required during Τ binding transmission；

Step 12:The data that UE is carried according to the TBS of the selection using the Τ transmission PUSCH of binding.

Wherein, in the embodiment of the present invention, existing form, i.e. table 1 are referred to as the first form, and the form newly proposed in the embodiment of the present invention is referred to as the second form, the first form and the second form can be pre-configured in UE.

In addition, UE upstream data is by base station scheduling, i.e. can also include before step 11：UE receives the configuration information that base station is sent, and the configuration information is used for the data for indicating the TTI transmission PUSCH carryings using binding；And, UE receives the schedule information that base station is sent, and the schedule information includes MCS index and RB number.

After UE receives schedule information, the index for obtaining corresponding TBS can be searched according to the MCS wherein included index and table 2 (table 2 can be pre-configured in UE)_S, afterwards further according to, RB number w_PRBWith the second form（Prior art is according to table 1) search the value for obtaining TBS.Afterwards just can be according to the TBS found value, and the configuration information received, using the data of the TTI transmission PUSCH carryings of binding.In the prior art only have the first form, no matter therefore Τ whether bind all use the first form, still, as stated in the Background Art, according to existing first form, when Τ is bound, the TBS, i.e. w in table 1 being less than or equal in RB under 3 and QPSK modulation systems_PRBFor 13 and/be that 0 10 corresponding TBS are can not to meet the rate requirement of data rate in PUSCH.Therefore, newly proposing second form in the embodiment of the present invention, second form is used when TTI bind, in second form RB is smaller and QPSK modulation systems it is right The TBS that answers is larger to meet data rate requirement in PUSCH.

Second form meets that RB is smaller, larger using QPSK modulation systems and TBS simultaneously, business datum when thus can transmit data rate in PUSCH by the way of Τ bindings.

The present embodiment proposes the second form as above, second form shows that TBS therein value is larger, the corresponding RB of TBS are smaller and the corresponding modulation systems of TBS are QPSK, because TBS value is larger, it disclosure satisfy that the requirement of PUSCH medium-rates, and bigger Turbo coding gains can be obtained and expense is reduced, preferable MCL values can be obtained using less RB and QPSK, therefore, coverage during data rate in PUSCH can be improved using aforesaid way.

Further, in data of the TBS selected according to the second form using the Τ transmission PUSCH carryings of binding, if the problem of losing more information bit according to existing transmission means meeting Cun Lost.Exemplified by binding continuous 4 subframes, prior art using Τ binding modes when transmitting data, 4 redundancy versions after one transmission block coding are respectively mapped in continuous 4 Τ, this 4 redundant version numbers can be 0,2,3,1.Information bit carry out Turbo 1/3 encode after, it is necessary to according to the big d of available resource, carry out rate-matched, when what redundant version number was represented is rate-matched selected data Turbo 1/3 coding after obtained by data in original position.But so transmission means is likely to result in Xin breaths Bi Te Lost mistakes.

For example, with reference to Fig. 2, it is assumed that TBS value=1736, corresponding RB numbers are 3, then bit number=12 (the subcarrier number in each RB that can be transmitted in a Τ）(the data symbol numbers in each RB of X 12）(the RB numbers of x 3）(the corresponding bit numbers of each QPSK modulation symbols of X 2）=864 bits.1736 information bits add the cyclic check (Cyclic Redundancy Check, CRC) of 24 bits first, then add（1736+24) Turbo 1/3 is completed after 2 check bits of χ to encode.The data to be transmitted by the way of Τ is bound include information bit and check bit, different redundancy versions represent the different original positions in data of the selected data after the codings of Turbo 1/3, different redundancy versions are expressed as RV0, RV1, RV2 and RV3, as can be seen from Figure 2, when the data that each subframe chooses 864 bits are transmitted, there can be the data not being selected between subframe, that is some information bits Bei Lost lose, as the data not being selected between RV0 and RV1 are lost if Bei Lost.

In order to solve this problem, the present invention provides following one embodiment.

Wherein, because the number of information bit is the TBS according to the selection of the second form, if according to the selection mode of prior art, can Lost mistake partial information bits.And in the present embodiment by the way of information bit is continuously chosen, because since whole information bits choosing starting point all continuously chosen, it is not in discontinuous situation, the covering to information bit the position that is indicated to RV1 of position indicated from RV0 can just be increased, it is possible to number of the reduction letter breath than special Lost mistakes.

Optionally, in order to ensure the continuous information bits since being chosen starting point for choosing whole, it can continuously circulate and choose the data that the Τ of binding can be transmitted, for example, with reference to Fig. 4, the data instance of 864 bits can be transmitted with each subframe, under the scene of 4 subframe bindings, the present embodiment can continuously choose the data of the bits of 864 x 4, the data continuously chosen, namely data of the bits of 864 x 4, corresponding redundant version number can be named as RV0.

Step 33:The data for the PUSCH carryings chosen using the Τ transmission of binding.

For example, when the Τ for continuously choosing the data of 864 4 bits and binding are 4, the data of selection being divided into the data of 4 parts, every part of 864 bits and transmitted in a Τ.

The present embodiment can transmit more data using Τ binding modes in shorter time delay, drop Low transmission time delay；By using larger TBS, it can make it that Turbo coding gains are bigger, header and cyclic check（Cyclic Redundancy Check, CRC) expense reduction；By using less RB numbers so that equivalent noise during link calculation keeps reduced levels；Change the mapping mode of Τ bindings so that more information bits can be transmitted；By using QPSK modulation systems, there is preferable link budget relative to 16QAM and 64QAM, it is possible to obtain bigger MCL.Coverage during data rate in PUSCH can be just improved through the above way.
