APPARATUS AND METHOD FOR TRANSMITTING AND RECEIVING DATA

摘要

The invention relates to a data-transmitting apparatus, which transmits a first control message to a data-receiving apparatus so as to allocate a first carrier serving as a subcarrier to the data-receiving apparatus, wherein said first control message contains information that the data-receiving apparatus requires for receiving multicast broadcast service (MBS) data. After the successful transmission of the first control message, the data-transmitting apparatus activates the first carrier to transmit MBS data to the data-receiving apparatus without the process of exchanging a second control message for activating a carrier. The data-transmitting apparatus transmits MBS data to the data-receiving apparatus via the first carrier.
