`
`4 Multiplexing, channel coding and interleaving
`
`4.1 General
`
`Data stream from/to MAC and higher layers (Transport block / Transport block set) is encoded/decoded to offer
`transport services over the radio transmission link. Channel coding scheme is a combination of error detection, error
`correcting, rate matching, interleaving and transport channels mapping onto/splitting from physical channels.
`
`4.2 Transport—channe| coding/multiplexing
`
`Data arrives to the coding/multiplexing unit in form of transport block sets once every transmission time interval. The
`transmission time interval is transport-channel specific from the set {l0 ms, 20 ms, 40 ms, 80 ms}.
`
`The following coding/multiplexing steps can be identified:
`
`Add CRC to each transport block (see Section 4.2.1)
`Channel coding (see Section 4.2.3)
`Rate matching (see Section 4.2.6)
`Insertion of discontinuous transmission (DTX) indication bits (see Section 4.2.7)
`Interleaving (two steps, see Section 4.2.4 and 4.2.10)
`Radio frame segmentation (see Section 4.2.5)
`Multiplexing of transport channels (two steps, see Section 4.2.2 and 4.2.8)
`Physical channel segmentation (see Section 4.2.9)
`Mapping to physical channels (see Section 4.2.1 1)
`
`The coding/multiplexing steps for uplink and downlink are shown in Figure 4-1 and Figure 4-2 respectively.

`<Editor ’s note: Code multiplexing is not used in uplink as a working assumption in WGI.. >
`
`Primarily, transport channels are multiplexed as described above, i.e. into one data stream mapped on one or several
`physical channels. However, an alternative Way of multiplexing services is to use code multiplexing, Which corresponds
`to having several parallel multiplexing chains as in Figure 4-1, resulting in several data stream, each mapped to one or
`several physical channels. This code multiplexing is used only for doWnlink DSCHs. For the other transport channels
`including doWnlink DCHs, the code multiplexing shall not be used.
`
`4.2.1 Error detection
`
`Error detection is provided on transport blocks through a Cyclic Redundancy Check. The CRC is 16, 8 or 0 bits and it
`is signalled from higher layers What CRC length that should be used for each transport channel.
`
`4.2.1.1 CRC Calculation
`
`The entire transport block is used to calculate the CRC parity bits for each transport block. The parity bits are generated
`by one of the following cyclic generator polynomials:
`
`gcm<D> = D“ + D” + D5 +1
`
`gcRcg(D) = D8 + D7 + D4+ D3 + D +1
`
`bN, and the parity bits by p1,p2,
`Denote the bits in a transport block delivered to layer 1 by b1, b2, b3,
`length of the transport block and L is 16, 8, or 0 depending on What is signalled from higher layers.
`
`pL. N is the
`
`The encoding is performed in a systematic form, Which means that in GF(2), the polynomial

`
`yields a remainder equal to 0 When divided by gCRC16(D). Similarly,
`
`b1DN+7 : b2DN+6 :
`
`: bND8 : p1D7 : p2D6 :
`
`: p7D1 : pg
`
`yields a remainder equal to 0 When divided by gCRCg(D).
`
`4.2.1.2 Relation between input and output of the Cyclic Redundancy Check
`
`bN, Where N is the length of the transport block. The bits after CRC
`Bits delivered to layer 1 are denoted b1, b2, b3,
`attachment are denoted by W1, W2, W3,
`WN+L, Where L is 16, 8, or 0. The relation betWeen b and W is:
`
`Wk=bk
`
`l(=l,2,3,...N
`
`Wk = p(L+1_(k_N))
`
`l( = N+l , N+2, N+3, N+L
`
`4.2.2 13‘ Multiplexing
`
`Fix rate transport channels that are characterised by the same transport format attributes (as defined in 25.302) can be
`multiplexed before coding. When this multiplexing step is present, the transport blocks from different transport
`channels are serially concatenated. Denote the number of transport channels (TrCHs) by R, the number of transport
`blocks on each TrCH by P, and the number of bits in each transport block, including CRC bits, by K. The bits before
`multiplexing can then be described as folloWs:
`
`Bits from transport block 1 of transport channel 1: W111, W112, W113,
`
`W11K
`
`Bits from transport block 2 of transport channel 1: W121, W122, W123,
`
`W12K
`
`Bits from transport block P of transport channel 1: W1p1, W1p2, W1p3,

`<Note.' Above it is assumed that all transport blocks have the same size. There are cases when the total number of bits
`that are sent during a transmission time interval is not a multiple ofthe number oftransport blocks. Afew padding bits
`are then needed but the exact insertion point (in the multiplexing chain) ofthese bits isforfurther study.>

`If the transport blocks or multiplexed transport blocks are longer than [504] bits (including CRC bits), they are
`segmented before convolutional encoding. Denote the number of transport blocks before coding by P and the number

`multiplexing is performed, all transport blocks of a transport channel in the same transmission time interval are
`multiplexed together, i.e. P=l. The bits before segmentation can then be described as follows:
`
`Bits in transport block lbefore segmentation: d1, 1, dm, d1,3,

`If M S [504], no segmentation is performed. If M > [504] the following parameters are calculated:
`
`Number of code blocks: S = round_up( PM / [504] )

`
`4.2.3.2.2 Trellis termination for Turbo coding
`
`Trellis termination is performed by taking the tail bits from the shift register feedback after all information bits are
`encoded. Tail bits are added after the encoding of information bits.
`
`Trellis termination for PCCC
`
`The first three tail bits shall be used to terminate the first constituent encoder (upper switch of Figure 4-4 in lower
`position) while the second constituent encoder is disabled. The last three tail bits shall be used to terminate the second
`constituent encoder (lower switch of Figure 4-4 in lower position) while the first constituent encoder is disabled.
`
`The transmitted bits for trellis termination shall then be
`
`X(t) Y(t)X(t+1) Y(t+l) X(t+2) Y(t+2) X’(t) Y’(t) X’(t+l) Y’(t+1)X’(t+2) Y’(t+2).
`
`Trellis termination for SCCC
`
`The conventional method of trellis termination is used also for SCCC in which the tail bits are taken from the shift
`
`register feedback after all bits are encoded. The tailing bits of the outer encoder are included in the interleaver. The
`outer code is terminated first with two additional input bits taken from the shift register feedback (dotted line of Figure
`4-5), the outer code thus, after puncturing, outputs three additional bit that are feeded into the interleaver. After that all
`bits have been encoded from the inner encoder (included the interleaved tail bit of the outer encoder), two additional
`input bits are taken from the shift register feedback of the inner encoder producing four tail bits (dotted line of Figure
`4-5). Thus the total overhead due to the tailing bits is 3*2+4 =10 bits
`
`4.2.3.2.3 Turbo code internal interleaver
`
`Figure 4-6 depicts the overall 8 State PCCC Turbo coding scheme including Turbo code internal interleaver. The Turbo
`code internal interleaver consists of mother interleaver generation and pruning. For arbitrary given block length K, one
`mother interleaver is selected from the 207 mother interleavers set. The generation scheme of mother interleaver is
`described in section 4.2.3.2.3. 1. After the mother interleaver generation, l-bits are pruned in order to adjust the mother
`
`interleaver to the block length K. The definition of l is shown in section 4.2.3.2.3.2.

`
`The interleaving consists of three stages. In first stage, the input sequence is written into the rectangular matrix row
`by row. The second stage is intra-row permutation. The third stage is inter-row permutation. The three-stage
`permutations are described as follows, the input block length is assumed to be K (320 to 5120 bits).
`
`First Stage:
`
`(1) Determine a row number R such that
`
`R=l0 (K = 481 to 530 bits; Case-l)
`
`R=20 (K = any other block length except 481 to 530 bits; Case-2)

`(2) Determine a column number C such that
`
`Case-1', C =p : 53
`Csae-2',
`
`(i)
`
`find minimum prime p such that,
`
`O =< (p+l)-K/R,
`
`(ii) if (0 =<p-K/R) then go to (iii),
`
`else C =p+l.
`
`(iii) if (0 =< p-1-K/R) then C=p-l,
`
`else C = p.
`
`(3) The input sequence of the interleaver is written into the RXC rectangular matrix row by row.
`
`Second Stage:
`
`A. If C = Q
`
`(A- 1) Select a primitive root go from Table 4-2.
`
`(A-2) Construct the base sequence c(z) for intra-row permutation as:
`
`c(z') = [go ><c(z'—l)]modp ,
`
`2' =l,2,... , (p-2)., c(O) = l.
`
`(A-3) Select the minimum prime integer set {qj } (j=l,2,. ..R-l) such that
`
`g.c.d{q,-,p-1} =1
`
`41> 6
`
`Q/' > 40--1)
`where g.c.d. is greatest common divider. And qo = l.

`ppm =q,-, j= 0, l,

`
`(A-5) Perform the j-th (j = 0, l, 2,
