摘要:
A method of transmitting data packets in a mobile communication system using at least one relay station (RS) and using at least two frequency carriers is disclosed. More specifically, the method comprises transmitting at least one subpacket of a first data packet to a mobile station (MS) on a first frequency carrier, and transmitting at least one subpacket of a second data packet to the MS via the at least one RS. Here, the at least one subpacket of second data packet from the at least one RS is transmitted on a second frequency carrier, a first subpacket of the first data packet and a first subpacket of the second data packet is transmitted via a main channel of the first frequency carrier and the main channel of the second frequency carrier, respectively, and at least one subsequent subpacket of the first data packet and at least one subsequent subpacket of the second data packet are transmitted via at least one assistant channel of the first frequency carrier and the at least one assistant channel of the second frequency carrier, respectively.

A method for receiving data at different frequencies includes receiving a first transmission packet including data at a first carrier frequency, and receiving a second transmission packet comprising data at a second carrier frequency. The method further includes maintaining communication with transmission entities which transmit the first and second transmission packets, and identifying reception quality of the first and second transmission packets. In addition, a method for retransmitting subpackets includes transmitting a first subpacket of a packet transmission from at least two transmitting entities. Upon receiving a non-acknowledgement NACK generated responsive to the first subpacket, the method further includes alternating transmission of subsequent subpackets from different transmitting entities. Upon receiving an acknowledgement ACK generated responsive to any subpackets of the packet transmission, the method further includes transmitting a first subpacket of a new packet transmission.

A method of transmitting channel quality information (CQI) to an access network (AN) in a system having at least one carrier is disclosed. More specifically, the method includes receiving at least one packet from the AN, each of which includes an indicator, wherein the indicator provides buffer level information and ceasing transmission of the CQI of at least one non-anchor carrier to the AN if the buffer level information indicates that there is no more packet to be transmitted to an access terminal (AT).
