    • A method for retransmitting data using an HARQ method and a mobile station using the same in a wireless telecommunications system are disclosed herein. When all bits of a resource index field in an uplink basic assignment A-MAP received from a base station through a specific frame are set to 1, the mobile station may not retransmit an HARQ sub-packet from an uplink subframe within the specific frame. In this case, the mobile station may retransmit an HARQ sub-packet from an uplink subframe within a frame subsequent to the specific frame. At this point, the uplink subframe and resource index of the subsequent frame respectively correspond to the subframe and resource index having the same index and resource index of an uplink subframe predetermined in association with the retransmission of the mobile station in a previous frame. The resource index corresponds to information indicating where the assigned resource is positioned within the corresponding subframe and how large the size of the assigned resource is. Alternatively, the mobile station may receive once again the uplink basic assignment A-MAP, so as to retransmit the HARQ sub-packet from an uplink subframe designated by the uplink basic assignment A-MAP.
    • 本文公开了一种在无线电信系统中使用HARQ方法重传数据的方法和使用该方法的移动台。 当通过特定帧从基站接收的上行链路基本指派A-MAP中的资源索引字段的所有比特被设置为1时,移动站可以不从特定帧内的上行链路子帧重传HARQ子分组。 在这种情况下,移动台可以在特定帧之后的帧内的上行链路子帧中重传HARQ子分组。 此时,后续帧的上行链路子帧和资源索引分别对应于与先前帧中的移动站的重新发送相关联地预定义的具有与上行链路子帧相同的索引和资源索引的子帧和资源索引。 资源索引对应于指示所分配资源在相应子帧内的位置以及所分配资源的大小有多大的信息。 或者,移动台可再次接收上行链路基本指配A-MAP,以从由上行链路基本指配A-MAP指定的上行链路子帧重传HARQ子包。
