A method and base station are provided for allocating a Hybrid Automatic Repeat Request (HARQ) channel according to service flow types. The method allocates a DownLink (DL) HARQ channel by a base station to a mobile station which can be provided with data corresponding to at least one Service Flow (SF) in a wireless communication system. At least one of a plurality of HARQ channels is mapped to a first SF. It is determined whether to allocate the mapped at least one HARQ channel as a dedicated HARQ channel of the first SF based on whether traffic of the first SF exists in a transmission queue corresponding to the first SF. Therefore, dedicated HARQ channels for a delay intolerant SF, such as a Voice over Internet Protocol (VoIP) SF, can be managed without loss of a maximum throughput for a delay tolerant SF such as a Best Effort (BE) SF.
