ation of a Hadamard sequence and a sequence Z, defined as where and X1,X2,....XX5,X16, are same as in the definition of the sequence a above. The Hadamard sequences are obtained as the rows in a matrix H8 constructed recur- sively by: H=(1) The rows are numbered from the top starting with row 0 (the all ones sequence). Denote the nth Hadamard sequence as a row of H8 numbered from the top, n = 0,1,2, .,255, in the sequel. Furthermore, let hn(i) and z(i) denote the ith symbol of the sequence hn and Z, respec- tively where i = 0,1,2,...,255 and i = 0 corresponds to the leftmost symbol. The UMTS Network and Radio Access Technology The kth SSC, Cssciok=1,2,3,...,16is then defined as (1+j)x(h,(0)x2(0), hm(1)xz(1), (2) X z(2), h,,(255)xz(255)), where m = 16x(k - 1) and the leftmost chip in the sequence corresponds to the chip transmitted first in time. The 64 secondary SCH sequences are constructed such that their cyclic shifts are unique, i.e. a non-zero cyclic shift less than 15 of any of the 64 sequences is not equiva- lent to some cyclic shift of any other of the 64 sequences. Also, a non-zero cyclic shift less than 15 of any of the sequences is not equivalent to itself with any other cyclic shift less than 15. Table 4.?? describes the sequences of SSCs used to encode the 64 different scrambling code groups. The entries in Table 4.?? denote what SSC to use in the differ- ent slots for the different scrambling code groups, e.g. the entry '7' means that SSC Cssc,7 shall be used for the corresponding scrambling code group and slot. See SSCs for secondary SCH in [8]. 4.3.13 Downlink Power Control Procedure The network determines the transmit power of the downlink channels. Generally, the transmit power ratio between different downlink channels does not have specification and may change with time. 4.3.13.1 DPCCH/DPDCH Downlink Power Control The downlink transmit power control procedure controls simultaneously the DPCCH power and that of its corresponding DPDCHs. The power control loop adjusts the power of the DPCCH and D
