RADIO COMMUNICATION SCHEME FOR PROVIDING MULTIMEDIA BROADCAST AND MULTICAST SERVICES (MBMS)
First Claim
1. A method of providing a broadcast or multicast service, the method comprising:
- transmitting control information via a second downlink common physical channel such that at least one terminal is able to receive data of the broadcast or multicast service which is transmitted via a first downlink common physical channel; and
transmitting the data via the first downlink common physical channel,wherein the second downlink common physical channel comprises at least one of a TFCI (Transport Format Combination Indicator) field and a Pilot field, andwherein the second downlink common physical channel further comprises data of a service which is different from the transmitted data of the broadcast or multicast service.

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.

10. A method of receiving a broadcast or multicast service, the method comprising:
-
receiving control information via a second downlink common physical channel to receive data of the broadcast or multicast service which is received via a first downlink common physical channel from a network; and receiving the data via the first downlink common physical channel, wherein the second downlink common physical channel comprises at least one of a TFCI (Transport Format Combination Indicator) field and a Pilot field, and wherein the second downlink common physical channel further comprises data of a service which is different from the received data of the broadcast or multicast service. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
