Denoting by E the rate matching output sequence length for the r-th coded block, and rv idx the redundancy version
number for this transmission, the rate matching output bit sequence is e k , k = 0,1,..., E −1
.
Define by G the total number of bits available for the transmission of one transport block.
′ N L Q m where Q m is equal to 2 for QPSK, 4 for 16QAM and 6 for 64QAM, and where N L is equal to 1 for
blocks mapped onto one transmission layer and is equal to 2 for blocks mapped onto two or four transmission layers.

5.1.4.2 Rate matching for convolutionally coded transport channels and control
information
The rate matching for convolutionally coded transport channels and control information consists of interleaving the
(0) (1) (2)
three bit streams, d
k
, d
k
and d
k
, followed by the collection of bits and the generation of a circular buffer as
depicted in Figure 5.1.4-2. The output bits are transmitted as described in subclause 5.1.4.2.2.
