Abstract

A system for mobile communication includes a base station and a mobile station. The base station includes a first transmitting unit operable to transmit to a mobile station, identifying information for multicast data to be to the mobile station, and a second transmitting unit operable to transmit the data on a shared channel to the mobile station, wherein the data is identified by the information transmitted. The mobile station includes a first receiving unit operable to receive from the base station identifying information for the multicast data, and a second receiving unit operable to receive the data on the shared channel from the base station, by the information received.

1 . A system for mobile communication comprising: 
 a base station comprising: 
 a first transmitting unit operable to transmit to a mobile station, identifying information for multicast data to be to the mobile station, and  
 a second transmitting unit operable to transmit the data on a shared channel to the mobile station, wherein the data is identified by the information transmitted; and  
   a mobile station comprising: 
 a first receiving unit operable to receive from the base station identifying information for the multicast data, and  
 a second receiving unit operable to receive the data on the shared channel from the base station, by the information received.  
   
   
   
       2 . The system of  claim 1 , wherein the shared channel is same channel among a plurality of mobile stations.  
   
   
       3 . The system of  claim 1 , wherein at least a portion of the data transmitted on the shared channel is for a plurality of mobile stations.
