Abstract: A method of transmitting packet in a mobile station is provided. The method includes determining whether a resource reserved for a special purpose is overlapped with a resource for transmitting a packet by the mobile station, on the basis of resource allocation information on the mobile station, and delaying the transmission of the packet if the reserved resource is overlapped with the resource for transmitting the packet. Accordingly, it is possible to increase uplink packet transmission efficiency without increasing downlink overhead, by avoiding or adjusting collision of an uplink packet transmission with a time-frequency resource reserved for another purpose.

Abstract: A method of performing HARQ performed by a user equipment (UE) is provided. The method includes receiving a bundling indicator which indicates the number of bundled downlink subframes, determining whether at least one bundled downlink subframe is missed by comparing the bundling indicator with the number of detected bundled downlink subframes, generating a representative ACK/NACK signal when no bundled downlink subframe is missed, and transmitting the representative ACK/NACK signal on an uplink channel. Recovery capability is maximized and the packet loss is reduced in such a situation that less number of ACK/NACK signals are fed back than that of downlink packets.
