Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out It clearly and completely describes, it is clear that described embodiment is a part of the embodiments of the present invention, rather than whole embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art's every other embodiment obtained without creative labor, all should belong to the scope of protection of the invention.
It should be understood that the technical solution of the embodiment of the present invention can be applied to LTE communication system, also can be applied in other similar communication systems therewith.
It should be understood that, in embodiments of the present invention, user equipment (English: User Equipment, abbreviation: UE) terminal (Terminal) can be referred to as, mobile station (English: Mobile Station, abbreviation: MS), mobile terminal (Mobile Terminal) etc., the user equipment can be through wireless access network (English: Radio Access Network, abbreviation: RAN) it is communicated with one or more core nets, such as, user equipment can be mobile phone (or being " honeycomb " phone), computer etc. with mobile terminal, such as, user equipment can also be portable, pocket, hand-held, built-in computer or vehicle-mounted mobile device, they and wireless access network are handed over Change voice and/or data.
In embodiments of the present invention, base station can be the evolved base station (English: Evolutional Node B in LTE system or LAA-LTE system, abbreviation: eNB or e-NodeB), macro base station, micro-base station (also referred to as " small base station "), femto base station, access website (English: Access Point, abbreviation: AP) or transmission website (English: Transmission Point, abbreviation: TP) etc., the present invention does not limit this.But for convenience of description, following the description will be illustrated by taking base station and user equipment as an example.
The traffic scheduling of LTE system is to send control channel by base station to realize, the control channel can carry the scheduling information of upstream or downstream Data Data channel, the scheduling information includes such as RA information, MCS, HARQ process number etc. controls information, and user equipment (UE) carries out the reception of downstream data channel or the transmission of uplink data channels according to the scheduling information carried in above-mentioned control channel.For scheduling, most crucial is to determine MCS, resource block to RB pair distribution and the number of plies for scheduled UE.Specifically, base station can choose MCS and the number of plies based on the channel state information CSI that UE is reported for UE so that downlink data is dispatched as an example；Then further according to the size for the data packet TBS for currently needing to transmit, to determine the distribution of RB pair.Correspondingly, being distributed after UE receives physical downlink control channel PDCCH according to the RB pair in the PDCCH, then MCS and number of plies instruction carry out the operation such as demodulating and decoding to determine TBS.As can be seen that TBS and RB pair distribution, MCS and the number of plies have corresponding relationship, this corresponding relationship is pre-defined, for example is respectively stored in UE and base station in table form.
LTE system can carry out continuing evolution towards the direction using the bigger bandwidth of higher frequency point, mean that the LTE system in future can use the scheduling of bigger bandwidth, or the requirement in view of high frequency points low time delay, using the scheduling of more subframes, the resource units quantity once dispatched will be made to greatly increase, mentioned here To resource units it is similar with the RB pair in current LTE system, but protect RE quantity it is possible that variation.Since the resource units quantity of scheduling greatly increases, TBS specified in current TBS table can be made not enough, it is therefore desirable to design bigger TBS to be adapted to the demand.
On the whole, if according to original TBS Table Design thinking, to design bigger TBS, design complexities can be very big, without better scalability, i.e., often there is the demand for increasing TBS, it is necessary to design a TBS according to above-mentioned rule, and the TBS table in standard can be more and more huger, is not suitable for maintenance.The mentality of designing of existing TBS table is introduced first below:
Step 1: CQI and MCS are determined
Determine the operation interval of SNR, such as from -7dB to 20dB；
In the above-mentioned section SNR, to various modulation systems (QPSK, 16QAM, 64QAM) and code rate (1/3,1/2,2/3,3/4,5/6 etc.) link simulation is carried out, obtains the link-simulation curve of a plurality of BLER-to-SNR, every curve represents a kind of embodiment of spectrum efficiency；
Based on above-mentioned curve, with BLER=0.1, SNR spacing is 1.892dB, selection is from 15 from the combination (corresponding different spectrum efficiency) of above-mentioned Different Modulations and code rate, as CQI, specific index 1 to 15 as shown in Table 1, and index 0 and overflowed for CQI；It can be seen that spectrum efficiency shown in the column of the rightmost side one of table 1 is what order of modulation * code rate obtained, by taking index 1 as an example, spectrum efficiency is 0.1523 that the order of modulation 2 of QPSK is obtained multiplied by code rate 78/1024；
Interpolation is carried out to above-mentioned 15 CQI, obtains 29 MCS.
Table 1.CQI table
Step 2: it is distributed based on MCS and RB pairs, establishes TBS table
In principle, it is based on above-mentioned MCS, in conjunction with the distribution of RB pair, so that it may determine the original bit number transmitted, i.e. transport block size TBS.
But the interleaver of the Turbo channel encoder of LTE is required to meet QPP characteristic, to realize the ability of Turbo code parallel processing, and then improves the efficiency of Turbo.Specifically, Turbo encoder only receives the value for meeting the limited quantity of QPP principle, the value for specifically meeting QPP interleaver is shown in Table 2.As can be seen from Table 2, the column of Ki mono- are exactly the limited coded block size CBS that Turbo encoder is supported.The maximum CBS of the Turbo encoder support of LTE is 6144, if TBS is greater than 6144, needs for the TB to be divided into multiple CB to be separately encoded, and all TBS that LTE is currently supported, the CB of support equal sizes is divided, and the filling bit after division is 0.Maximum CBS value limitation 6144 is because although the CB of Turbo code is longer, coding gain is bigger, and to 6144 this rank, the increase of coding gain is unobvious, and continues growing CBS, will increase encoder complexity.

The interleaver parameter of table 2.Turbo encoder
Therefore, it when constructing TBS table, cannot simply be distributed based on MCS and RB pair to determine.But first the numerical value set for meeting QPP interleaver is selected according to QPP characteristic；Then distributed according to MCS and RB pair and determine interim TBS, then selected from above-mentioned numerical value set one from the interim immediate numerical value of TBS as final TBS.In addition it is also necessary to consider the segmentation of TB, that is, equal-sized CBS also must be in above-mentioned numerical value set each of after being segmented.
The relationship that the TBS and MCS and RB pair specifically finally determined is distributed is as shown in Table 3 and Table 4, It can be seen that the quantity for the RB pair distribution that current TBS table maximum is supported is 110 RB pair.
Table 3.MCS index, order of modulation, the relationship of TBS index
The relationship that table 4.TBS numerical value and TBS index and RB pair distribute
Step 3: the case where being mapped to multilayer for 1 code word introduces new mapping relations
Above-mentioned TBS table is the transmission for supporting one layer.If a numeral can be transmitted in multilayer, also need to extend TBS.Since MCS is that current channel condition determines, and as the RB pair quantity of one layer and N layer transmission occupancy is, then extending TBS can be by later looking into the RB pair quantity distributed in PDCCH multiplied by N times the TBS table of above-mentioned single layer.
