General procedures
Data and control streams from/to MAC layer are encoded /decoded to offer transport and control services over the radio
transmission link. Channel coding scheme is a combination of error detection, error correcting, rate matching,
interleaving and transport channel or control information mapping onto/splitting from physical channels.
5.1
CRC calculation
Denote the input bits to the CRC computation by a 0 , a1 , a 2 , a 3 ,..., a A−1 , and the parity bits by p 0 , p1 , p 2 , p 3 ,..., p L −1 ,
where A is the size of the input sequence and L is the number of parity bits. The parity bits are generated by one of
the following cyclic generator polynomials:
-
g CRC24A (D ) = [ D 24 + D 23 + D 18 + D 17 + D 14 + D 11 + D 10 + D 7 + D 6 + D 5 + D 4 + D 3 + D + 1] for a CRC length
L = 24 ;
-
g CRC24B (D ) = [ D 24 + D 23 + D 6 + D 5 + D + 1] for a CRC length L = 24 ;
-
g CRC24C (D ) = [ D 24 + D 23 + D 21 + D 20 + D 17 + D 15 + D13 + D 12 + D 8 + D 4 + D 2 + D + 1] for a CRC length L = 24 ;
-
g CRC16 (D ) = [ D 16 + D 12 + D 5 + 1] for a CRC length L = 16 ;
-
g CRC11 (D ) = [ D 11 + D10 + D 9 + D 5 + 1] for a CRC length L = 11;
-
g CRC6 (D ) = [ D 6 + D 5 + 1] for a CRC length L = 6 .
The encoding is performed in a systematic form, which means that in GF(2), the polynomial:
a0 D A+ L−1 + a1 D A+ L−2 + ... + a A−1 D L + p0 DL−1 + p1 D L−2 + ... + p L−2 D1 + p L−1
yields a remainder equal to 0 when divided by the corresponding CRC generator polynomial.
The bits after CRC attachment are denoted by b0 , b1 , b2 , b3 ,..., b B −1 , where B = A + L . The relation between ak and bk
is:
bk = a k
for k = 0,1,2,..., A − 1
ETSI
3GPP TS 38.212 version 15.2.0 Release 15
bk = p k − A
10
ETSI TS 138 212 V15.2.0 (2018-07)
for k = A, A + 1, A + 2,..., A + L − 1 .
5.2
Code block segmentation and code block CRC attachment
5.2.1
Polar coding
The input bit sequence to the code block segmentation is denoted by a 0 , a1 , a 2 , a 3 ,..., a A−1 , where A > 0 .
if I seg = 1
Number of code blocks: C = 2 ;
else
Number of code blocks: C = 1
end if
A' =  A / C  ⋅ C ;
for i = 0 to A'− A − 1
a 'i = 0 ;
end for
for i = A'− A to A'−1
a'i = ai −( A'− A) ;
end for
s =0;
for r = 0 to C − 1
for k = 0 to A' / C − 1
crk = a' s ;
s = s +1;
end for
The sequence cr 0 , cr1 , cr 2 , cr 3 ,..., cr ( A'/ C −1) is used to calculate the CRC parity bits p r 0 , p r1 , p r 2 ,..., p r (L −1) according to
Subclause 5.1 with a generator polynomial of length L .
for k = A' / C to A' / C + L − 1
crk = pr (k − A'/ C ) ;
end for
end for
The value of A is no larger than 1706.
5.2.2
Low density parity check coding
The input bit sequence to the code block segmentation is denoted by b0 , b1 , b2 , b3 ,..., b B −1 , where B > 0 . If B is larger
than the maximum code block size K cb , segmentation of the input bit sequence is performed and an additional CRC
sequence of L = 24 bits is attached to each code block.
ETSI
3GPP TS 38.212 version 15.2.0 Release 15
11
ETSI TS 138 212 V15.2.0 (2018-07)
For LDPC base graph 1, the maximum code block size is:
-
K cb = 8448 .
For LDPC base graph 2, the maximum code block size is:
-
K cb = 3840 .
Total number of code blocks C is determined by:
if B ≤ Kcb
L=0
Number of code blocks: C = 1
B′ = B
else
L = 24
Number of code blocks: C = B / (K cb − L ) .
B′ = B + C ⋅ L
end if
The bits output from code block segmentation are denoted by c r 0 , c r1 , c r 2 , c r 3 ,..., c r (K r −1) , where 0 ≤ r < C is the code
block number, and K r = K is the number of bits for the code block number r .
The number of bits K in each code block is calculated as:
K '= B ' / C ;
For LDPC base graph 1,
Kb = 22 .
For LDPC base graph 2,
if B > 640
Kb = 10 ;
elseif B > 560
Kb = 9 ;
elseif B > 192
Kb = 8 ;
else
Kb = 6 ;
end if
find the minimum value of Z in all sets of lifting sizes in Table 5.3.2-1, denoted as Z c , such that K b ⋅ Z c ≥ K ' , and
set K = 22Z c for LDPC base graph 1 and K = 10Z c for LDPC base graph 2;

Polar coding
The bit sequence input for a given code block to channel coding is denoted by c 0 , c1 , c 2 , c 3 ,..., c K −1 , where K is the
number of bits to encode. After encoding the bits are denoted by d 0 , d1 , d 2 ,..., d N −1 , where N = 2 n and the value of n is
determined by the following:
Denote by E the rate matching output sequence length as given in Subclause 5.4.1;
If E ≤ (9 / 8) ⋅ 2 ( log 2 E −1) and K / E < 9 / 16
n1 = log 2 E  − 1 ;
else
n1 = log 2 E  ;
end if
Rmin = 1 / 8 ;
n2 = log 2 (K / Rmin ) ;
n = max{min{n1 , n2 , nmax }, nmin }
where nmin = 5 .
UE is not expected to be configured with K + nPC > E , where n PC is the number of parity check bits defined in
Subclause 5.3.1.2.
5.3.1.1
Interleaving
The bit sequence c 0 , c1 , c 2 , c 3 ,..., c K −1 is interleaved into bit sequence c' 0 , c'1 , c' 2 , c' 3 ,..., c' K −1 as follows:
c′k = cΠ ( k ) , k = 0,1,..., K − 1
where the interleaving pattern Π (k ) is given by the following:
if I IL = 0
Π (k ) = k , k = 0,1,..., K − 1
else
k =0;
for m = 0 to K ILmax − 1

if Π max
IL (m) ≥ K IL − K
(
)
max
;
Π(k ) = Π max
IL (m) − K IL − K
k = k +1;
end if
end for
end if
where Π max
is given by Table 5.3.1.1-1 and K ILmax = 164 .

Low density parity check coding
The bit sequence input for a given code block to channel coding is denoted by c 0 , c1 , c 2 , c 3 ,..., c K −1 , where K is the
number of bits to encode as defined in Subclause 5.2.2. After encoding the bits are denoted by d 0 , d1 , d 2 ,..., d N −1 , where
N = 66 Z c for LDPC base graph 1 and N = 50Z c for LDPC base graph 2, and the value of Z c is given in Subclause
5.2.2.
For a code block encoded by LDPC, the following encoding procedure applies:
1) Find the set with index iLS in Table 5.3.2-1 which contains Z c .
2) for k = 2Z c to K − 1
if ck ≠< NULL >
d k − 2 Z c = ck ;
else
ck = 0 ;
d k −2 Zc =< NULL > ;
end if
end for
[
]
3) Generate N + 2Z c − K parity bits w = w0 , w1 , w2 ,..., wN +2 Z −K −1 T such that H ×  c  = 0 , where
c

T
c = [c0 , c1 , c2 ,..., cK −1 ] ; 0 is a column vector of all elements equal to 0. The encoding is performed in GF(2).

For LDPC base graph 1, a matrix of H BG has 46 rows with row indices i = 0,1, 2,..., 45 and 68 columns with
column indices j = 0,1, 2,..., 67 . For LDPC base graph 2, a matrix of H BG has 42 rows with row indices
i = 0,1,2,..., 41 and 52 columns with column indices j = 0,1,2,...,51 . The elements in H BG with row and
column indices given in Table 5.3.2-2 (for LDPC base graph 1) and Table 5.3.2-3 (for LDPC base graph 2) are
of value 1, and all other elements in H BG are of value 0.
The matrix H is obtained by replacing each element of H BG with a Z c × Z c matrix, according to the following:
-
Each element of value 0 in H BG is replaced by an all zero matrix 0 of size Z c × Z c ;
Each element of value 1 in H BG is replaced by a circular permutation matrix I(Pi , j ) of size Z c × Z c , where i
and j are the row and column indices of the element, and I(Pi , j ) is obtained by circularly shifting the identity
matrix I of size Z c × Z c to the right Pi , j times. The value of Pi , j is given by Pi , j = mod (Vi , j , Z c ) . The value of
Vi , j is given by Tables 5.3.2-2 and 5.3.2-3 according to the set index iLS and LDPC base graph.
4) for k = K to N + 2Z c − 1
d k −2 Zc = wk − K ;

The entire transport block is used to calculate the CRC parity bits. Denote the bits in a transport block delivered to layer
1 by a 0 , a1 , a 2 , a 3 ,..., a A−1 , and the parity bits by p 0 , p1 , p 2 , p 3 ,..., p L −1 , where A is the payload size and L is the
number of parity bits. The lowest order information bit
a0 is mapped to the most significant bit of the transport block
as defined in Subclause 6.1.1 of [TS38.321].
The parity bits are computed and attached to the UL-SCH transport block according to Subclause 5.1, by setting L to
24 bits and using the generator polynomial g CRC24A (D ) if A > 3824 ; and by setting L to 16 bits and using the
generator polynomial g CRC16 (D ) otherwise.
The bits after CRC attachment are denoted by b0 , b1 , b2 , b3 ,..., b B −1 , where B = A + L .

LDPC base graph selection
For initial transmission of a transport block with coding rate R indicated by the MCS index according to Subclause
6.1.4.1 in [6, TS 38.214] and subsequent re-transmission of the same transport block, each code block of the transport
block is encoded with either LDPC base graph 1 or 2 according to the following:
-
if A ≤ 292 , or if A ≤ 3824 and R ≤ 0.67 , or if R ≤ 0.25 , LDPC base graph 2 is used;
-
otherwise, LDPC base graph 1 is used,
where A is the payload size as described in Subclause 6.2.1.
6.2.3
Code block segmentation and code block CRC attachment
The bits input to the code block segmentation are denoted by b0 , b1 , b2 , b3 ,..., b B −1 where B is the number of bits in the
transport block (including CRC).
Code block segmentation and code block CRC attachment are performed according to Subclause 5.2.2.
The bits after code block segmentation are denoted by c r 0 , c r1 , c r 2 , c r 3 ,..., c r (K r −1) , where r is the code block number
and K r is the number of bits for code block number r according to Subclause 5.2.2.

The total number of code blocks is denoted by C and each code block is individually LDPC encoded according to
Subclause 5.3.2.
After encoding the bits are denoted by d r 0 , d r1 , d r 2 , d r 3 ,..., d r ( N −1) , where the values of N r is given in Subclause 5.3.2.

6.2.5
Rate matching
Coded bits for each code block, denoted as d r 0 , d r1 , d r 2 , d r 3 ,..., d r ( N −1) , are delivered to the rate match block, where r is
r
the code block number, and N r is the number of encoded bits in code block number r . The total number of code
blocks is denoted by C and each code block is individually rate matched according to Subclause 5.4.2 by setting
I LBRM = 1 if higher layer parameter rateMatching is set to limitedBufferRM and by setting I LBRM = 0 otherwise.
After rate matching, the bits are denoted by f r 0 , f r1 , f r 2 , f r 3 ,..., f r ( E −1) , where E r is the number of rate matched bits for
r
code block number r .

The following information is transmitted by means of the DCI format 2_0 with CRC scrambled by SFI-RNTI:
-
Slot format indicator 1, Slot format indicator 2, …, Slot format indicator N.
The size of DCI format 2_0 is configurable by higher layers up to 128 bits, according to Subclause 11.1.1 of [5, TS
38.213].
7.3.1.3.2
Format 2_1
DCI format 2_1 is used for notifying the PRB(s) and OFDM symbol(s) where UE may assume no transmission is
intended for the UE.
The following information is transmitted by means of the DCI format 2_1 with CRC scrambled by INT-RNTI:

The size of DCI format 2_1 is configurable by higher layers up to 126 bits, according to Subclause 11.2 of [5, TS
38.213]. Each pre-emption indication is 14 bits.
7.3.1.3.3
Format 2_2
DCI format 2_2 is used for the transmission of TPC commands for PUCCH and PUSCH.
The following information is transmitted by means of the DCI format 2_2 with CRC scrambled by TPC-PUSCH-RNTI
or TPC-PUCCH-RNTI:
-
block number 1, block number 2,…, block number N
The parameter tpc-PUSCH or tpc-PUCCH provided by higher layers determines the index to the block number for an
UL of a cell, with the following fields defined for each block:
-
-
Closed loop indicator – 0 or 1 bit.
-
For DCI format 2_2 with TPC-PUSCH-RNTI, 0 bit if the UE is not configured with high layer parameter
twoPUSCH-PC-AdjustmentStates, in which case UE assumes each block in the DCI format 2_2 is of 2 bits; 1
bit otherwise, in which case UE assumes each block in the DCI format 2_2 is of 3 bits;
-
For DCI format 2_2 with TPC-PUCCH-RNTI, 0 bit if the UE is not configured with high layer parameter
twoPUCCH-PC-AdjustmentStates, in which case UE assumes each block in the DCI format 2_2 is of 2 bits; 1
bit otherwise, in which case UE assumes each block in the DCI format 2_2 is of 3 bits;
TPC command –2 bits
If the number of information bits in format 2_2 is less than the payload size of format 0_0 as defined in the initial DL
bandwidth part in the same serving cell, zeros shall be appended to format 2_2 until the payload size equals that of
format 0_0 as defined in the initial DL bandwidth part in the same serving cell.
7.3.1.3.4
Format 2_3
DCI format 2_3 is used for the transmission of a group of TPC commands for SRS transmissions by one or more UEs.
Along with a TPC command, a SRS request may also be transmitted.
The following information is transmitted by means of the DCI format 2_3 with CRC scrambled by TPC-SRS-RNTI:
-
block number 1, block number 2, …, block number B
ETSI
3GPP TS 38.212 version 15.2.0 Release 15
97
ETSI TS 138 212 V15.2.0 (2018-07)
where the starting position of a block is determined by the parameter startingBitOfFormat2-3 provided by higher
layers for the UE configured with the block.
If the UE is configured with higher layer parameter srs-TPC-PDCCH-Group = typeA for an UL without PUCCH and
PUSCH or an UL on which the SRS power control is not tied with PUSCH power control, one block is configured for
the UE by higher layers, with the following fields defined for the block:
-
SRS request – 0 or 2 bits. The presence of this field is according to the definition in Subclause 11.4 of [5,
TS38.213]. If present, this field is interpreted as defined by Table 7.3.1.1.2-24.
-
TPC command number 1, TPC command number 2, ..., TPC command number N, where each TPC command
applies to a respective UL carrier provided by higher layer parameter cc-IndexInOneCC-Set
If the UE is configured with higher layer parameter srs-TPC-PDCCH-Group = typeB for an UL without PUCCH and
PUSCH or an UL on which the SRS power control is not tied with PUSCH power control, one block or more blocks is
configured for the UE by higher layers where each block applies to an UL carrier, with the following fields defined for
each block:
-
SRS request – 0 or 2 bits. The presence of this field is according to the definition in Subclause 11.4 of [5,
TS38.213]. If present, this field is interpreted as defined by Table 7.3.1.1.2-24.
-
TPC command –2 bits
If the number of information bits in format 2_3 is less than the payload size of format 0_0 as defined in the initial DL
bandwidth part in the same serving cell, zeros shall be appended to format 2_3 until the payload size equals that of
format 0_0 as defined in the initial DL bandwidth part in the same serving cell.
7.3.2
CRC attachment
Error detection is provided on DCI transmissions through a Cyclic Redundancy Check (CRC).
The entire payload is used to calculate the CRC parity bits. Denote the bits of the payload by a 0 , a1 , a 2 , a 3 ,..., a A−1 , and
the parity bits by p 0 , p1 , p 2 , p 3 ,..., p L −1 , where A is the payload size and L is the number of parity bits. Let
a '0 , a '1 , a '2 , a '3 ,..., a ' A+ L −1 be a bit sequence such that a 'i = 1 for i = 0,1,..., L − 1 and a 'i = a i − L for
i = L, L + 1,..., A + L − 1 . The parity bits are computed with input bit sequence a'0 , a'1 , a'2 , a'3 ,..., a' A+ L −1 and attached
according to Subclause 5.1 by setting L to 24 bits and using the generator polynomial g CRC24C (D ) . The output bit
b0 , b1 , b2 , b3 ,..., bK −1 is
bk = a k
for k = 0,1,2,..., A − 1
bk = p k − A
for k = A, A + 1, A + 2,..., A + L − 1 ,
where K = A + L .
After attachment, the CRC parity bits are scrambled with the corresponding RNTI x rnti , 0 , x rnti ,1 ,..., x rnti ,15 , where xrnti , 0
corresponds to the MSB of the RNTI, to form the sequence of bits
is:
c k = bk
c0 , c1 , c2 , c3 ,..., cK −1 . The relation between ck and bk
for k = 0, 1, 2, …, A + 7
ck = (bk + xrnti ,k − A−8 ) mod 2 for k = A + 8 , A + 9 , A + 10 ,..., A + 23 .
7.3.3
Channel coding
Information bits are delivered to the channel coding block. They are denoted by c0 , c1 , c 2 , c3 ,..., c K −1 , where K is the
number of bits, and they are encoded via Polar coding according to Subclause 5.3.1, by setting nmax = 9 , I IL = 1 ,
wm
n PC = 0 , and nPC = 0 .
After encoding the bits are denoted by d 0 , d1 , d 2 , d 3 ,..., d N −1 , where N is the number of coded bits.
