Abstract

The invention discloses a method and a system for determining the size of transmission blocks. The method comprises the following steps: determining the transmission block and determining the size of the transmission blocks of the third layer or the size of the transmission blocks of the fourth layer according to the number NPRB of physical resource blocks of the transmission blocks and the size index ITBS of the transmission blocks; or determining the size of the transmission blocks of the third layer according to the number of the physical resource blocks of the transmission blocks, the size index of the transmission blocks and the size mapping relation of the transmission blocks of the first layer and the transmission blocks of the third layer; and or determining the size of the transmission blocks of the fourth layer according to the number of the physical resource blocks of the transmission blocks, the size index of the transmission blocks and the size mapping relation of the first layer of the transmission blocks and the fourth layer of the transmission blocks.

Description

A kind of method and system of definite transmission block size
Technical field
The present invention relates to wireless communication system, relate in particular to a kind of method and system of definite transmission block size.
Background technology
Senior Long Term Evolution (Long Term Evolution Advanced, abbreviating LTE-A as) system is as Long Term Evolution (Long term evolution, abbreviate LTE as) evolution standard of system, multiple-input and multiple-output (the Multipie Input Multiple Output that strengthens has been proposed, abbreviate MIMO as) technology, this technology can be supported maximum 8 * 8 uplink/downlink antenna configuration, improves the covering and the throughput of cell edge.
In radio communication, transmitting terminal uses many antennas, takes the mode of spatial reuse to improve transmission rate, and receiving terminal such as user terminal (User Equipment is called for short UE) also use many antennas.Along with the increase of number of antennas, channel sequence (rank) has also increased, and layer (layer) number that is used for transfer of data has also correspondingly increased.Each TB can only transmit on 2 layers at most in the LTE system, and the LTE-A system then supports each transmission block (Transport Block is called for short TB) to transmit on 4 layers at most.
Provide in the existing standard under the 4 antenna situations, transmission block bit size (the Transport Block Size of transmission block under 1 sheaf space is multiplexing, be called for short TBS) and 1 layer to 2 layers TBS conversion mapping relations table, be used for determining the multiplexing size of TB down of 2 sheaf spaces, under 8 antenna situations, 1 TB is mapped to a plurality of layers, and the size that is mapped to 3,4 layers of TB is not defined in the existing protocol, therefore improves the size that TB transmits and seem particularly important in 3,4 layers.
Can obtain 1 layer of TBS by the mode of tabling look-up in R8, the R9 agreement, existing R8 only supports the mapping of 1 layer of TBS to 2 layer of TBS, can be by (Index Transport Block Size is called for short I with the transport block size index TBS) as the line index row, (Num Physical Resource Block is called for short N with the Physical Resource Block number PRB) from 1 layer of TBS table, know 1 layer of TBS of TB as column index.For 2 layers of TB, as 1≤N PRB≤ 55 o'clock, by 1 layer of TBS table, by index (I TBS, 2N PRB) find out corresponding TBS in 1 layer of table, promptly as the value of 2 layers of TBS.As 56≤N PRB, obtain the N of 2 layers of TB at≤110 o'clock PRBAnd I TBS, pass through N PRBAnd I TBSFrom 1 layer of table, find 1 layer of corresponding TBS, by 1 layer to 2 layers TBS conversion mapping relations table, find out and 1 layer of corresponding 2 layers of TBS of TBS again.
The mapping of 1 layer of TBS to 3,4 layers of TBS, before carrying out chnnel coding, data to transmission are carried out cyclic redundancy check (Cyclic Redundancy Check, be called for short CRC) handle, promptly add some CRC bits in data trailer, so that it is whether correct in the decoding of receiving terminal judgment data, when to long TB (when transmission block is longer than 6144 bits) when transmitting, to carry out segment processing to it, when TB is added TB CRC, to add CRC check information respectively on the code block after the segmentation (Code Block is called for short CB).A complete transmission block, when it is longer than 6144bit, should comprise TBS+TBCRC+CBCRC and, formulate the TBS form, a value that only needs to determine TBS gets final product.
By the approximate multiple relation of 1 layer of TBS to 3,4 layers of TBS, the TBS after determining to shine upon, wherein TBS_L1 represents 1 layer of TBS, TBS_LN represents the TBS after the mapping of n layer, TB 1_ crc represents the TB CRC of 1 layer of TBS correspondence, TB N_ crc represents the corresponding TB CRC of TBS after the mapping of n layer, cb 1_ crc represents the CB CRC after 1 layer of TBS cut apart, cb N_ crc represents the corresponding CB CRC of TBS after the mapping of n layer, and concrete formula is as follows:
(TBS_L1+TB 1_crc+cb 1_crc)×n＝TBS_LN+TB N_crc+cb N_crc
The approximation TBS_LN of 3,4 layers of TBS that draw by above formula, when TBS_LN＜149776bit, 3 layers of TBS reuse 1,2 layer of TBS as far as possible, and 4 layers of TBS reuse the principle of 1,2,3 layer of TBS as far as possible, and this principle does not additionally increase too much TBS, to make things convenient for transmitting and scheduling, when TBS_LN＞149776bit,, should be divided exactly by QPP interleaver parameter k for newly-increased TBS, increase the matching of multilayer TBS, reduce to fill (padding).
Do not provide the technical scheme of transmission that how to realize 3,4 layers of TB in the prior art.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of method and system of definite transmission block size, for the transmission that realizes 3,4 layers of TB provides solution.
In order to solve the problems of the technologies described above, the invention provides a kind of method of definite transmission block size, comprising: according to the Physical Resource Block number N of transmission block PRBWith transport block size index I TBSDetermine that transmission block determines 3 layers of transmission block size or 4 layers of transmission block size; Perhaps, determine 3 layers of transmission block size according to Physical Resource Block number, transport block size index and 1 layer of transmission block size to 3 layer transmission block size mapping relations of transmission block; Perhaps, determine 4 layers of transmission block size according to Physical Resource Block number, transport block size index and 1 layer of transmission block size to 4 layer transmission block size mapping relations of transmission block.
