    摘要: Provided is a method of retransmitting and receiving a packet in heterogeneous network environment. A terminal and a relay base station receive a packet transmitted from a macro base station, and the relay base station informs the terminal of whether the packet is successively received or not. When the packet fails to be received, the terminal is configured to receive the erroneous packet again from at least one of the macro base station and the relay base station. The macro base station and the relay base station may be configured to retransmit the packet through joint processing JP) transmission, and the terminal may be configured to receive the JP transmission. Thus, the method allows the m optimization of a HARQ process and scheduling scheme to efficiently utilize a relay and radio resources, thereby leading to a maximum capacity and quality of wireless network.
