Notes/Equations
 This model is used to implement radio frame segmentation. When the transmission time interval is longer than 10 msec, the input bit sequence is segmented and mapped onto consecutive Fi radio frames. After rate matching in the DL, the input bit sequence length is guaranteed to be an integer multiple of F_{i}.
The input bit sequence is denoted by x_{i} 1, x_{i} 2, x_{i} 3, ..., x_{iXi}. where i is the TrCH number and X_{i} is the number bits. The F_{i} output bit sequences per TTI are denoted by y_{i,ni} 1, y_{i,ni} 2, y_{i,ni} 3, ..., y_{i,ni} X_{i} where n_{i} is the radio frame number in current TTI and Y_{i} is the number of bits per radio frame for TrCH i. The output sequences are defined as follows:
where, ,
The n_{i} th segment is mapped to the n_{i} th radio frame of the transmission time interval.Y_{i} = ( X_{i} / F_{i} ) is the number of bits per segment.
 Each firing, one token is consumed by pin SizeIn; this token indicates the effective length of data block input at pin DataIn. After radio frame segmentation, the data block is output at pin DataOut; a token is generated by pin DataOut to indicate the effective length of the output data block.
 All transport channel information must be in the form of arrays.
The DynTFSetArray parameter requires an integer array. The correct format is transport block size 1, transport block set size 1, transport block size 2, transport block set size 2, etc. The size of this array must be a multiple of 2, and the transport block set size must be a multiple of the relative transport block size.
TFSetSizeArray indicates how many pairs of transport block and transport block set sizes are contained in a certain transport channel. For example:
When setting TTIArray, CRCArray and CHCodingTypeArray values, refer to the following table. TFSetSizeArray = "3 2" means the first three pairs of transport block size and transport block set size belong to the first transport channel, and the next two pairs belong to the second transport channel.
 TFSetSizeArray = "2 2 2" means the first two pairs of transport block size and transport block set size belong to the first transport channel, the next two pairs belong to the second transport channel and the last two pairs belong to the third transport channel.
Settings for TTIArray, CRCArray and CHCodingTypeArray Values
TTIArray CRCArray CHCodingTypeArray Time Value Coding Value Coding Value 10 msec 0 No CRC 0 No Coding 0 20 msec 1 8 bits 1 1/2 CC 1 40 msec 2 12 bits 2 1/3 CC 2 80 msec 3 16 bits 3 1/3 TC 3 24 bits 4 CC = convolutional coding; TC = turbo coding  This model fires once per radio frame. Each firing, this model inputs a data block of one radio frame, and the previous model (first interleaving) inputs a data block of one TTI. ADS will automatically fire this model multiple times if necessary; for example, if TTI = 40 msec, this model will fire four times while the previous model fires once.
