Patent ID: 8031739

Claim:
A channel transmission method comprising the steps of: generating one of multiple transmission signals to be transmitted on a corresponding one of different types of downlink physical channels used in a mobile communication system with a sectorized cell architecture; selecting and switching a pattern of a first code from an orthogonal code, a unique sector scrambling code, and a unique multimedia-broadcast-multicast-service scrambling code according to the type of a corresponding physical channel to multiply the generated said one transmission signal by the selected pattern of the first code under unified control; if the transmission signal is multiplied by the orthogonal code or the unique sector scrambling code as the first code, then further multiplying the transmission signal by an intracell common scrambling code used in common among sectors in a same cell; and transmitting the transmission signal multiplied by at least one of the first code and the intracell common scrambling code on the corresponding physical channel.
