Abstract
Disclosed is a channel allocation method in a CDMA communication system. The method comprises receiving from a UTRAN one SF node CSF,k out of 2m−1 SF nodes (where m is an integer larger than 3) arranged in the form of a tree having a mother node and child nodes; searching a group including the received SF node CSF,k in accordance with Formula (1) below; spreading a signal on a dedicated physical data channel (DPDCH) with an OVSF code corresponding to a selected one of the received SF node and its child nodes in the searched group; and spreading a signal on a dedicated physical control channel (DPCCH) with an OVSF code corresponding to an SF node determined by Formula (2) below based on the received SF node.
