<p>A method and apparatus are provided for the selection of sequences used for the transmission of signals from user equipments in a cellular communication system. The sequences can be selected either through planning or through pseudo-random hopping among a set of sequences. With planning, the serving Node B signals the sequence assignment for each cell, which remains invariable in time. With pseudo-random sequence hopping, which has the same pattern in all cells, the serving Node B signals the initial sequence, from a set of sequences, which can be different among cells. The signals can be transmitted either through a data channel or through a control channel. The initial sequence used in the control (or data) channel is signaled by the serving Node B. The initial sequence used in the data (or control) channel is selected to be the sequence in a set of sequences with number equal to a shift value relative to the first sequence as signaled by the serving Node B for the control (or data) channel.</p> |
