Abstract

The embodiment of the invention discloses a kind of data transmission method and device, relate to wireless communication field, for providing transport block size TBS on a kind of new carrier type NCT carrier wave to determine method, to reduce the wasting of resources.In the method, according to the Physical Resource Block PRB size distributed for present physical DSCH Downlink Shared Channel PDSCH, determine that PRB indexes；Table look-up according to the modulating-coding class information that current PDSCH is used, obtain the TBS index that described modulating-coding class information is corresponding；Table look-up according to described TBS index and described PRB index, obtain a TBS；Being enlarged by a described TBS according to expansion factor N, wherein N is the numerical value not less than 1, the TBS that the TBS after will be enlarged by is used as current PDSCH, and the TBS used according to current PDSCH carries out data transmission.Use the present invention can reduce the wasting of resources.

Description

Data transmission method and device
Technical field
The present invention relates to wireless communication field, particularly relate to a kind of data transmission method and device.
Background technology
Long Term Evolution (Long Term Evolution, LTE) system version 11(Rel-11) and version before in carrier wave It is non-new carrier type (New Carrier Type, NCT) carrier wave, wherein Physical Downlink Control Channel (Physical Downlink Control Channel, PDCCH) by the top n OFDM (Orthogonal of a descending sub frame Frequency Division Multiplexing, OFDM) symbol transmission, wherein possible for N value is 1,2,3,4, and N=4 Only allow to occur in the system that system bandwidth is 1.4MHz, as shown in Figure 1.Community own reference signal (Cell-specific Reference signals, CRS) at all support Physical Shared Channels (Physical Downlink Shared Channel, PDSCH) descending sub frame that transmits to transmit, system can support single antenna port transmission (P0), two antenna end oral instructions Defeated (P0, P1) or four antenna ports transmission (P0, P1, P2, P3), as shown in Figure 2.
In order to reduce overhead, LTE Rel-11 discusses definition NCT carrier wave, this NCT carrier wave does not transmit traditional PDCCH, i.e. PDCCH shown in Fig. 1.Based on user-specific reference signal (UE-specific reference in this NCT carrier wave Signals, URS) carry out data demodulation, URS structure is as shown in Figure 3.CRS does not transmits or every 5ms take a sub-frame transmission and Only transmit P0.
The determination method of the transport block size (Transport block size, TBS) on non-NCT carrier wave is as follows:
Terminal obtains according to the signaling receiving base station transmission and transmits the modulating-coding class information that current PDSCH is used IMCSPhysical Resource Block (PRB) size with distribution
Step 1: terminal according toDetermine that PRB indexes NPRBIf present sub-frame is time division duplex (Time division Duplex, TDD) special subframe, thenOtherwise
Step 2: terminal is according to IMCS, tabling look-up 1 determines that the transmission number of modulation levels that used of PDSCH and TBS index ITBS。
Step 3: further:
1) if PDSCH uses non-multilayer spatial multiplexing transmission, then terminal is further according to ITBSAnd NPRB, tabling look-up 2 determines this TBS in PDSCH；
2) if PDSCH use two-layer spatial multiplexing transmission:
If 1≤NPRB≤ 55, then terminal is further according to ITBSWith 2 NPRB, tabling look-up 2 determines the TBS in this PDSCH；
If 56≤NPRB≤ 110, then terminal is further according to ITBSAnd NPRB, tabling look-up 2 obtains TBS_L1, then basis TBS_L1 tables look-up 3, and to obtain TBS_L2 be the TBS in this PDSCH；
3) if PDSCH uses three sheaf space multiplexing transmission:
If 1≤NPRB≤ 36, then terminal is further according to ITBSWith 3 NPRB, tabling look-up 2 determines the TBS in this PDSCH；
If 37≤NPRB≤ 110, then terminal is further according to ITBSAnd NPRB, tabling look-up 2 obtains TBS_L1, then basis TBS_L1 tables look-up 4, and to obtain TBS_L3 be the TBS in this PDSCH；
4) if PDSCH use four-level space multiplexing transmission:
If 1≤NPRB≤ 27, then terminal is further according to ITBSWith 4 NPRB, tabling look-up 2 determines the TBS in this PDSCH；
If 28≤NPRB≤ 110, then terminal is further according to ITBSAnd NPRB, tabling look-up 2 obtains TBS_L1, then basis TBS_L1 tables look-up 5, and to obtain TBS_L4 be the TBS in this PDSCH.

In LTE system, data channel uses Turbo coding, for improving coding and decoding speed, one encoding block of system specialization Greatest length is 6144 bits.If transmission block adds cyclic redundancy check (CRC) position (the Cyclic Redundancy of 24 bits Check, CRC) after length more than 6144, then need that transmission block is carried out code block segmentation and obtain the code block that multiple length is less, The length k ∈ K of the most each code block, K is as shown in table 6.Then less code block is carried out respectively Turbo coding.
