Title:
THE APPARATUS AND METHOD FOR RETRANSMITTING DATA BASED ON HARQ SCHEME IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2011/021786
Kind Code:
A3
Abstract:
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.
