<p>A cell identifier is indicated in a signal to be transmitted in a cellular communication system by selecting one of a number, M, of codes, wherein each of the codes has a length N of code symbols, and wherein the selected code is associated with the cell identifier. The selected code is transmitted as a number, N, of reference symbols. The M codes are orthogonal with one another over their length, N, of the code symbols and also over at least one subgroup of length L of the code symbols, wherein L<M. During cell search, whether to use all N reference symbols or one or more subgroups of the reference symbols to construct one of M possible orthogonal codes depends on what type of cell search is being performed.</p> |
