Release 8 22 3GPP TS 36.212 V8.1.0 (2007-11) Code block segmentation and code block CRC attachment are performed according to subclause 5.1.2. The bits after code block segmentation are denoted by c r0 , cr1, cr2 , cr3 ,..., cr( K r −1) , where r is the code block number and K r is the number of bits for code block number r. 5.2.2.3 Channel coding of UL-SCH Code blocks are delivered to the channel coding block. The bits in a code block are denoted by c r0 , cr1, cr2 , cr3 ,..., cr( K r −1) , where r is the code block number, and K r is the number of bits in code block number r. The total number of code blocks is denoted by C and each code block is individually turbo encoded according to subclause 5.1.3.2. ( i) ( i) ( i) ( i) After encoding the bits are denoted by dr0 , dr 1 , dr2 , dr3 ,..., d r( Dr − 1) , with i = 0,1, and 2 and where Dr is the number of bits on the i-th coded stream for code block number r, i.e. D K + 4 . 5.2.2.4 Rate matching ( i) r = r Turbo coded blocks are delivered to the rate matching block. They are denoted by dr0 , dr 1 , dr2 , dr3 ,..., d r( Dr − 1) , with i = 0,1, and 2 , and where r is the code block number, i is the coded stream index, and D r is the number of bits in each coded stream of code block number r. The total number of code blocks is denoted by C and each coded block is individually rate matched according to subclause 5.1.4.1. After rate matching, the bits are denoted by e r0 , er1, er2, er3,..., er( E r −1) , where r is the coded block number, and where E r is the number of rate matched bits for code block number r. 5.2.2.5 Code block concatenation The bits input to the code block concatenation block are denoted by e r0 , er1, er2, er3,..., er( E r −1) for r = 0,..., C −1 and where E r is the number of rate matched bits for the r-th code block. Code block concatenation is performed according to subclause 5.1.5. The bits after code block concatenation are denoted by f 0 , f1, f2, f3,..., f G −1 , where G is the total number of coded bits for transmission excluding the bits used for control transmission, when control information is multiplexed with the UL- SCH transmission. 5.2.2.6 Channel coding of control information The coding rate of the control information when multiplexed with the data transmission is given by the modulation scheme and the coding rate used for the UL-SCH transmission. Different coding rates for the control information are achieved by allocating different number of coded symbols for its transmission. The bits output from the control information coding are denoted by q 0 , q1, q2, q3,..., q Q −1 . [Note from the editor: the value Q needs to be a multiple of Q m so that modulation symbols do not mix control and data information.] 5.2.2.7 Data and control multiplexing The control and data multiplexing is performed such that control is present on both slots in the subframe and so that the control is mapped to resources around the demodulation reference signals. In addition, the multiplexing ensures that control and data information are mapped to different modulation symbols. The inputs to the data and control multiplexing are the coded bits of the control information denoted by q0 , q1, q2, q3,..., q Q −1 and the coded bits of the UL-SCH denoted by f 0 , f1, f 2 , f 3 ,..., f G −1 . The output of the data and ( i) ( i) ( i) ( i) ( i) 3GPP
