To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with attached drawing to embodiment party of the present invention Formula is described in further detail.

Embodiment 1

Referring to fig. 2, the embodiment of the invention provides a kind of device of data transmission, which can be terminal or base It stands, which includes: coding module 101, determining module 102, selecting module 103 and transmission module 104.

Coding module 101 obtains the second data for encoding to the first data to be transmitted；

When terminal will transmit data to base station or when base station is to terminal transmission data, coding module 101 obtains to be passed Defeated data, using data to be transmitted as the first data, in order to improve the anti-interference ability of the first data, to the first data into Row coding, obtains the second data.

Coding module 101 can encode the first data to be transmitted using any coding mode, such as to be transmitted The first data carry out Turbo2/3 or Turbo1/3 coding, obtain the second data.

For example, the size of data of the first data to be transmitted is 1000, then Turbo1/3 coding is carried out to the first data, obtained To the second data, then the size of data of the second data is 3000.

The detailed process that first data are carried out with Turbo1/3 coding is the prior art, is no longer described in detail herein.

Determining module 102, in multiple wireless sub-frames and multiple wireless sub-frames needed for determining the second data of transmission The size of data that can carry of each wireless sub-frame；

When terminal transmits the second data to base station, alternatively, determining module is true when base station is to the second data of terminal transmission Surely multiple wireless sub-frames needed for the second data are transmitted, the second data are then transmitted on determining wireless sub-frame.

Wherein it is determined that module determines the process for the size of data that each wireless sub-frame in multiple wireless sub-frames can carry It is as follows:

For each wireless sub-frame, the number for transmitting available bit in total of a transmission block is expressed as G, i.e. G is The resource that a transmission block can occupy on this wireless sub-frame, in embodiments of the present invention, G are illustrated in bit levels =288.

Enable G`=G/ (N_L*Q_m), N_LIt is equal to 2 when using transmission diversity, in the case of other, N_LEqual to one transmission block reflects It is mapped to the number namely N of layer_LEqual to 1.When the modulation system used is QPSK, Q_m=2；When the modulation system used for When 16QAM, Q_m=4；When the modulation system used is 64QAM, Q_m=6.

Enabling y=G`modC, C is the number of code block, and the number of code block is related with the size of data of the first data, if first When the size of data of data is within the scope of 0-6144, C=1, if the size of data of the first data is within the scope of 6145-12289 When, C=2, if the size of data of the first data is within the scope of 12290-184334, C=3, and so on.

Enable E_r=N_L*Q_m* y, E_rIt indicates the size of data that can be carried on the wireless sub-frame, namely is every time the wireless son Frame selects size of data for E_r。

For example, G=288, N_L=1, the modulation system that the present invention uses is QPSK namely Q_m=2, then G`=G/ (NL*Q_m) =144, the size of data of the first data is 1000,1000 within the scope of 0-6144, then C=1；Then y=G`modC=144, E_r =N_L*Q_m* y=1*2*144=288, i.e., the size of data that can be carried on the wireless sub-frame are 288 bits, namely selection every time The size of data of data is 288 bits.

It should be noted that calculate the data that can be carried on the wireless sub-frame by the above process big for each wireless sub-frame It is small, and the size of data that can be carried on each wireless sub-frame may be identical, it is also possible to it is different.

Selecting module 103, the data that can be carried for the size of data and each wireless sub-frame according to the second data are big It is small, from selecting the third data transmitted on each wireless sub-frame, the third number transmitted on each wireless sub-frame in the second data According to size of data it is identical as the size of data that each wireless sub-frame can carry；

Wherein, selecting module 103, comprising: first acquisition unit and first selecting unit.

First acquisition unit obtains the data selection of each wireless sub-frame for the size of data according to the second data Initial position；

When transmitting the second data, by the second Deta bearer on wireless sub-frame, therefore, it is necessary to be obtained by first acquisition unit The initial position for taking the data of each wireless sub-frame to select, according to the initial position that the data of each wireless sub-frame select, from the The third data being carried on the wireless sub-frame are selected in two data.

Wherein, first acquisition unit, comprising: the first computation subunit obtains subelement and the second computation subunit,.

First computation subunit, the data that can be carried for the size of data and each wireless sub-frame according to the second data Size, redundancy versions number needed for calculating the second data of transmission；

First computation subunit, the data that size of data and each wireless sub-frame for calculating the second data can carry The ratio of size；By the upper rounding of the ratio or lower rounding as redundancy versions number needed for the second data of transmission.

If the ratio is integer, the first computation subunit is directly using the ratio as superfluous needed for the second data of transmission Remaining number of versions；If the ratio is non-integer, the integer part of the ratio is added one to be used as transmission by the first computation subunit Redundancy versions number needed for second data；If the ratio is non-integer, the work that can also subtract one for the integer part of the ratio For redundancy versions number needed for the second data of transmission.

For example, the size of data of the second data is 3000 bits, the size of data that each wireless sub-frame can carry is 288 Bit, then the integer part that 3000 and 288 ratio is 10.4,10.4 is 10, in embodiments of the present invention by 10 plus 1 namely 11 As redundancy versions number RV needed for the second data of transmission_num。

Wherein, the initial position of the corresponding data selection of every kind of redundancy versions.

Subelement is obtained, for obtaining the superfluous of the third data transmitted on each wireless sub-frame according to redundancy versions number Remaining version serial number；

When transmitting the second data, redundancy versions, the corresponding number of each redundancy versions are selected from redundancy versions set According to the initial position of selection, the initial position of the corresponding data selection of redundancy versions of selection is obtained, according to the initial position, from The third data transmitted on each wireless sub-frame are selected in second data.It is transmitted on each wireless sub-frame therefore, it is necessary to obtain Third data redundancy versions serial number.

Wherein, the value range of the redundancy versions serial number for the third data transmitted on each wireless sub-frame is 0~redundancy version This number -1.

Wherein, subelement is obtained, is also used to obtain the System Frame Number of each wireless sub-frame；What it is according to each wireless sub-frame is System frame number and redundancy versions number, calculate the redundancy versions serial number of each wireless sub-frame.

Wherein, subelement is obtained, the System Frame Number and redundancy versions number according to each wireless sub-frame are also used to, by such as Lower formula (2) calculates the redundancy versions serial number of each wireless sub-frame:

rv_index=N_TTImod RV_num；(2)

Wherein, rv_indexFor the redundancy versions serial number of each wireless sub-frame, RV_numFor redundancy versions number, N_TTIFor each nothing The System Frame Number of line subframe.

For example, the System Frame Number of current wireless sub-frame is 23, then 23 and 11 remainder is 1, then current wireless sub-frame is superfluous Remaining version serial number 1.

In this step, redundancy versions sequence can also be selected from redundancy versions set according to the number for sending wireless sub-frame Number.For example, wireless sub-frame selects redundancy versions 0 when sending the second data for the first time, when sending the second data for the second time, wirelessly Subframe selects redundancy versions 1, RV_numWhen the second data of secondary transmission, wireless sub-frame selects redundancy versions RV_num- 1, RV_num+1 When the second data of secondary transmission, wireless sub-frame selects redundancy versions 0, circuits sequentially.

Wherein, the second computation subunit, for according to the size of data of the second data, redundancy versions number and each wireless The redundancy versions serial number for the third data transmitted in subframe calculates the initial position of the data selection of each wireless sub-frame.

Second computation subunit, specifically for the interleaver according to used in the size of data of the second data and the second data Line number calculates the columns of interleaver；According to the columns of interleaver, the size of data of the second data, redundancy versions number and each The redundancy versions serial number for the third data transmitted on wireless sub-frame calculates each wireless sub-frame by following formula (1) respectively The initial position of data selection:

Wherein, the line number of interleaver is fixed value 32, and the columns of interleaver is set according to the size of data of the first data It sets, and the columns of interleaver meets+4 < of size of data=(the line number * columns of the interleaver) minimum value of the first data.

For example, the size of data of the first data is 1000, then 1000+4 <=(columns of 32* interleaver), then calculate Columns to interleaver is 32.The size of data N of second data_cbIt is 3000, redundancy versions number RV_numIt is 11, each wireless son The redundancy versions serial number rv of frame_indexRespectively 0,1,2,3,4,5,6,7,8,9,10, then be calculated each by above formula The initial position of the data selection of wireless sub-frame is respectively 64,336,609,882,1154,1427,1699,1972,2245, 2517、2790。
