Method and device for efficiently retransmitting packets in wired/wireless network
First Claim
1. A packet retransmission request method used in a reception apparatus in a wired/wireless network, the method comprising:
- detecting continuity by detecting whether or not a sequence ID of a received packet is continuous with a start sequence ID or an end sequence ID of packets included in reception blocks which are generated in advance of the received packet;
depending on the result of the detection, manipulating reception blocks to be renewed or deleted or generating a new reception block by using the sequence ID of the received packet; and
transmitting an Explicit Block NACK (EBN) for requesting retransmission of lost packets in units of a block when discontinuity is detected.

Abstract
Provided a method and device for efficiently retransmitting packets of which transmissions failed in wired/wireless network including detecting continuity by detecting whether or not a sequence ID of a received packet is continuous with a start sequence ID or an end sequence ID of packets included in reception blocks which are generated in advance of the received packet; depending on the result of the detection, manipulating reception blocks to renew or delete the reception blocks or generate a new reception block by using the sequence ID of the received packet; and transmitting an EBN (Explicit Block NACK) for requesting retransmission of lost packets in units of a block when discontinuity is detected.

11. A packet retransmission request device used in a reception apparatus in a wired/wireless network, the device comprising:
-
a continuity detection unit detecting that a sequence ID of a received packet is continuous with a start sequence ID or an end sequence ID of packets included in existing reception blocks; a reception block manipulation unit renewing or deleting the reception blocks or generating a new reception block by using the sequence ID of the received packet depending on the result of the detection; and an Explicit Block NACK (EBN) transmission unit transmitting an EBN for requesting retransmission of lost packets in units of a block when discontinuity is detected. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
