Abstract:
1. A method for reordering received packets in a mobile telecommunication system supporting HARQ, the method comprising the steps of: inputting from a receiving-side HARQ entity an input of a packet and processing time spent by the packet going through an HARQ operation; when a gap corresponding to at least one missing packet among received packets is detected based on the input packet belonging to the received packets, waiting for the missing packet belonging to the gap to be received for a period of time obtained by subtracting the processing time from a predetermined maximum waiting value; outputting the received packets to an upper layer in an order, if the period of time expires; starting a reordering timer based on a value obtained by subtracting the processing time from the maximum waiting value when the gap is detected based on the input packet; and stopping the reordering timer when all missing packets having sequence numbers less than a sequence number of the input packet are successfully received before the expiration of the reordering timer.
