Method and apparatus for providing point-to-multipoint multimedia service in a mobile communications system
First Claim
1. A method of receiving a multimedia broadcast multicast service (MBMS) at a user equipment (UE) in a mobile communications system, the method comprising:
- receiving radio bearer (RB) information comprising multi code channel information on a control channel, the multi code channel information comprising at least two channelization codes, wherein the at least two channelization codes are spreading codes, orthogonal codes or orthogonal variable spreading factor (OVSF) codes;
receiving the MBMS on at least two physical channels which have been established based on the multi channel code information, the at least two physical channels mapped to a coded composite transport channel (CCTrCH); and
receiving a transport format combination indicator (TFCI) which indicates a transport format combination of the CCTrCH, wherein the TFCI is received only on a first physical channel among the at least two physical channels.

Abstract
The present invention relates to a method and apparatus for providing at least one user equipment (UE) with a point-to-multipoint multimedia service through two or more common physical channels in a mobile communications system. A radio network transmits a point-to-multipoint multimedia service through a plurality of physical channels using multiple codes. A user equipment (UE) receives multiple channel code information through a control channel from the radio network, configures a plurality of physical channels using the received multiple channel code information and receives the point-to-multipoint multimedia service through the configured physical channels.
