Abstract: A method for supporting short latency in a mobile communication system is provided to configure an existing subframe into plural temporal zones, use the temporal zones as a short latency dedicated zone, define dedicated channels in the short latency dedicated zone, and use a frame structure using the short latency dedicated zone and the dedicated channels, thereby processing data and services which requires short latency efficiently. A downlink SLZ(Short Latency Zone) is indicated in a first PUSC(Partial Usage Of Subchannels) zone. The SLZ will be at least one of PUSC, FUSC(Full Usage Of Subchannels), optional FUSC, AMC(Adaptive Modulation and Coding), and TUSC/TUSC2(Tile Usage Subchannel) zones. The location information of the SLZ is provided through pre-assigned information or broadcast information without using an UL-MAP(Uplink-MAP) message. An MS(Mobile Station) knows a section, to which the SLZ is provided, previously or receives the broadcast information to acquire the location of the SLZ. An SLDCCH(Short Latency Dedicated Control Channel) indicates the allocation information of an SLDDCH(Short Latency Dedicated Data Channel) and an SLDFCH(Short Latency Dedicated Feedback Channel). The allocation information includes a location in a subframe, and modulation and coding methods. Feedback for data transmitted in the SLZ is quickly performed to provide a feedback channel to support short latency.
