The block of bits 
shall be scrambled with a UE-specific scrambling sequence, resulting in a block of scrambled bits 
according to
where the scrambling sequence 
is given by clause 7.2. The scrambling sequence generator shall be initialised with 
at the start of each subframe where 
is the C-RNTI.
The block of scrambled bits 
shall be QPSK modulated as described in Clause 7.1, resulting in a block of complex-valued modulation symbols 
where 
.
The complex-valued symbols 
shall be divided into 
sets, each corresponding to one SC-FDMA symbol. Block-wise spreading shall be applied according to
where 
, 
and 
are given by Table 5.4.2C-1 for normal PUCCH format 5 and shortened PUCCH format 5, and 
is given by Table 5.4.2C-2 with 
provided by higher layers.
The block-wise spread complex-valued symbols shall be transform precoded according to
where 
, resulting in a block of complex-valued symbols 
.
