The data modulation for 3.84Mcps TDD (including 3.84 Mcps MBSFN IMB) and 7.68Mcps TDD is d
39、efined in clause 5 Data modulation for the 3.84 Mcps and 7.68Mcps options, the data modulation for 1.28Mcps TDD is defined in clause 5A Data modulation for the 1.28 Mcps option and the spreading modulation in clause 6 Spreading modulation. Table 1 shows the basic modulation parameters for the 7.68Mc

42、 a complex-valued sequence with identical real and imaginary components. The PSC, Cp, is defined as Cp= where and the left most index corresponds to the chip transmitted first in time. The 12 secondary synchronization codes, C0, C1, C3, C4, C5, C6, C8,C10,C12, C13, C14,C15 are complex valued with id
43、entical real and imaginary components, and are constructed from the position wise multiplication of a Hadamard sequence and a sequence z, defined as z = , where b = and x1, x2, x3, , x16 are the same as in the definition of the sequence a above. The Hadamard sequences are obtained as the rows in a m
44、atrix H8constructed recursively by: , where m = (16i) and the leftmost chip in the sequence corresponds to the chip transmitted first in time. 7.2 Code Allocation Three secondary SCH codes are QPSK modulated and transmitted in parallel with the primary synchronization code. The QPSK modulation carri
45、es the following information: - the code group that the base station belongs to (32 code groups:5 bits; Cases 1, 2); - the position of the frame within an interleaving period of 20 msec (2 frames:1 bit, Cases 1, 2); - the position of the SCH slot(s) within the frame (2 SCH slots:1 bit, Case 2). The
46、modulated secondary SCH codes are also constructed such that their cyclic-shifts are unique, i.e. a non-zero cyclic shift less than 2 (Case 1) and 4 (Case 2) of any of the sequences is not equivalent to some cyclic shift of any other of the sequences. Also, a non-zero cyclic shift less than 2 (Case
47、1) and 4 (Case 2) of any of the sequences is not equivalent to itself with any other cyclic shift less than 8. The secondary synchronization codes are partitioned into two code sets for Case 1 and four code sets for Case 2. The set is used to provide the following information: Case 1: Table 2: Code
48、Set Allocation for Case 1 Code Set Code Group 1 0-152 16-31The code group and frame position information is provided by modulating the secondary codes in the code set. Case 2: Table 3: Code Set Allocation for Case 2 Code Set Code Group 1 0-72 8-153 16-234 24-31The slot timing and frame position information is provided by the comma free property of the code word and the Code group is provided by modulating some of the secondary codes in the code set. The following SCH codes are allocated for each code set: Case 1 Code set 1: C1, C3, C5. Code set 2: C10, C13, C14.
