as 256 repetitions of the signature Ps(n) from the set of 16 Hadamard codes of length 16 (Table 4.14), where n = 0,...,15. The specifications in [8] define it as: Csig, (i)=P (i mod = 16), =0,1,...,4095.

We define them from the preamble scrambling codes Sc-acc,n and a preamble signature Csig,s (4.30) where Sc-acc,n and Csig,s are defined in the sequel. Code generation takes place as in PRACH, resulting in 32768 PCPCH scrambling codes in total. We define nth PCPCH access preamble scrambling code, where n = 8192, 8193,...,40959, as: (4.31) where the sequence Section 4.3.5.1 defines Clong,1,n When PRACH and PCPCH share access resources, the scrambling codes applied in PRACH preamble apply also to PCPCH preamble; and as in the PRACH part we divide the 32768 PCPCH preamble scrambling codes into 512 groups with 64 codes in each group. There exists a one-to-one correspondence between the group of PCPCH access preamble scrambling codes in a cell and the primary scrambling code used in the down- link of the cell. The kth PCPCH scrambling code within the cell with downlink primary scrambling code m, k= 16,17,...,79 and m= 0,1,2,...,511, corresponds to Sc-acc,n as de- fined in Section 4.3.5.7 with n= 64 x m + k + 8176. The UMTS Network and Radio Access Technology When PCPCH and PRACH share scrambling code resources and the index k is less than 16, the corresponding PRACH formulae apply. Otherwise, if the index k is greater than or equal to 16, the formula in this section applies. The CPCH-access burst preamble part carries one of the 16 different orthogonal complex signatures identical to the ones used by the preamble part of the random-access burst
