    • 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.
    • 提供了一种用于支持移动通信系统中的短等待时间的方法,以将现有子帧配置为多个时域,将时区作为短延时专用区,在短延时专用区定义专用信道,并使用帧结构 短延迟专用区和专用通道,从而有效地处理需要短延迟的数据和服务。 在第一PUSC(子信道的部分使用)区域中指示下行链路SLZ(短延迟区域)。 SLZ将至少是PUSC,FUSC(全部使用子信道),可选FUSC,AMC(自适应调制和编码)和TUSC / TUSC2(瓦片使用子信道)区域中的一个。 SLZ的位置信息通过预分配的信息或广播信息提供,而不使用UL-MAP(上行链路MAP)消息。 MS(移动台)先前知道提供SLZ的部​​分,或者接收广播信息以获取SLZ的位置。 SLDCCH(短延迟专用控制信道)指示SLDDCH(短延迟专用数据信道)和SLDFCH(短延迟专用反馈信道)的分配信息。 分配信息包括子帧中的位置,以及调制和编码方法。 快速执行在SLZ中传输的数据的反馈,以提供反馈信道来支持短延迟。
