Section: 5.4A.4.1 Slot-SPUCCH
Content: The block of bits shall be scrambled according to clause 5.4.2B. 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 block of complex-valued symbols is divided into (defined in Table 5.4A.4.1-1) sets, each corresponding to one SC-FDMA symbol. Transform precoding shall be applied according to clause 5.4.2B replacing with and replacing with . The variable, where represents the bandwidth of the SPUCCH format 4 in terms of resource blocks in the frequency domain, and is determined by higher layer signalling (n4numberOfPRB-r15, see TS 36.213[ Evolved Universal Terrestrial Radio Access (E-UTRA); Physical layer procedures ]  [4, Table 10.1.1-2] and TS 36.331[ Evolved Universal Terrestrial Radio Access (E-UTRA); Radio Resource Control (RRC); Protocol specification ]  [9]), and shall fulfil , where, is a set of non-negative integers.
