Title of Invention	RADIO COMMUNICATION SCHEME FOR PROVIDING MULTIMEDIA BROADCAST AND MULTICAST SERVICES(MBMS)
Abstract	A radio communication scheme applicable to UMTS providing packet data services, such as multimidia broadcast and multicast services (MBMS),to one or more user by modifying(augmenting)certain existing radio communication protocols while employing a new transport channel(a point-to-multipoint DSCH),and/or by establishing new physical downlink shared channels(C-PDSCH and D-PDSCH).An RLC layer is provided in a single CRNC so that the same MBMS can be transmitted to a plurality of terminals via a point-to-multipoint DSCH,with out having to repetitively provide many RLC layers in many SRNCs.Alternatively,a C-PDSCH(physical downlink shared channel for control)and a D-PDSCH(physical downlink shared channel for data)are established to allow periodic transmission of MBMS,permitting users to simultaneously access one or more MBMS.
