ABSTRACT:
A radio communication scheme applicable to UMTS providing packet data services, such as multimedia broadcast and multicast services (MBMS), to one or more users 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, without 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.
