Patent ID: 7792179

Claim:
An apparatus for producing a sequence of a predetermined length in a spread spectrum communication system, comprising: means for storing a plurality of predetermined sequences having lengths less than the predetermined length; means for arranging the plurality of predetermined sequences in an indexed list; means for selecting at least two of the plurality of predetermined sequences from the indexed list; and means for concatenating the selected predetermined sequences to produce the sequence of the predetermined length, wherein the means for selecting comprises: means for selecting a first sequence of the at least two of the plurality of predetermined sequences with an index value of n from the indexed list, and means for selecting each successive sequence of the at least two of the plurality of predetermined sequences with an index value incremented from that of the previously selected sequence from the indexed list, and wherein n is determined from at least one of A-F: A initial cell parameter assignment, B system frame number (SFN), C chip rate of transmission, D predetermined length of scrambling code, E identifier of intended receiver of data spread with the predetermined length spreading code, and F channelisation code employed.
