the cell group n id group and the number of the time slot n s for example according to c init u2514 n s 2 u2518 1 u00b7 2n id group 1 u00b7 2 16 n id group if the drs res are divided into multiple groups as shown in fig6 it is supported that the drs res are divided into two groups and the two drs groups support two types of the scrambling code sequences at the same time the cell specific scrambling code sequences supported by the two drs re groups may be the same or different the cell group specific scrambling code sequences supported by the two drs re groups may be the same or different in fig6 it is supported that the cell specific scrambling code sequences supported by the two drs re groups are different and the cell group specific scrambling code sequences supported by the two drs re groups are different in this way another parameter i e an index of the drs re group may be added when the initialization code of the cell specific scrambling code sequence and the initialization code of the cell group specific scrambling code sequence are generated the index of the drs re group is represented as g thus the initialization code of the cell specific scrambling code sequence may be generated according to the identity of the cell n id cell the number of the time slot n s and and the index of the drs re group g for example according to c init u2514 n s 2 u2518 1 u00b7 2n id cell 1 u00b7 2 16 g the initialization code of the cell group specific scrambling code sequence may be generated according to the identity of the.
