The data modulation for 3.84Mcps TDD (including 3.84 Mcps MBSFN IMB) and 7.68Mcps TDD is defined in
39、 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 7.68Mcps, 3.84M
40、cps (including 3.84 Mcps MBSFN IMB) and 1.28Mcps TDD options. Table 1: Basic modulation parameters Chip rate 7.68 Mchip/s same as FDD basic chiprate: 3.84 Mchip/s and 3.84 Mcps MBSFN IMB Low chiprate: 1.28 Mchip/s Data modulation QPSK,16QAM (HS-PDSCH, MBSFN S-CCPCH and E-PUCH only) QPSK,16QAM (HS-PD

42、x-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 identical r
43、eal 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 matrix H8c
44、onstructed recursively by: The rows are numbered from the top starting with row 0 (the all ones sequence). Denote the n:th Hadamard sequence hnas a row of H8numbered from the top, n = 0, 1, 2, , 255,in the sequel. Furthermore, let hm(l) and z(l) denote the lth symbol of the sequence hmand z, respect
45、ively where l = 0, 1, 2, , 255 and l = 0 corresponds to the leftmost symbol. The i:th secondary SCH code word, Ci, i = 0, 1, 3, 4, 5, 6, 8, 10, 12, 13, 14, 15 is then defined as Ci= (1 + j) , where m = (16i) and the leftmost chip in the sequence corresponds to the chip transmitted first in time. 7.2
46、 Code Allocation Three secondary SCH codes are QPSK modulated and transmitted in parallel with the primary synchronization code. The QPSK modulation carries the following information: - the code group that the base station belongs to (32 code groups:5 bits; Cases 1, 2); 16151413121110987654321, xxxxxxxxxxxxxxxx1,)1(11110=kHHHHHHkkkkk
