Method and system for communication acknowledgement

摘要

Disclosed is a method and apparatus for helping to reduce latency that may arise from requesting retransmission of non-received packets. A device carrying out the method may be arranged to not send negative acknowledgements for non-received packets. Further, in an implementation where the device is to send for each packet of an incoming sequence either a positive acknowledgement indicating that the device received the packet or a negative acknowledgement indicating that the device did not receive the packet (and constituting a request for retransmission of the packet), the device will send for each packet a positive acknowledgement regardless of whether the device received the packet. The device will thus send a positive acknowledgement for at least one packet even though the device did not receive the packet.

1. A method for a device, the method comprising:
the device receiving from a remote entity a signal comprising a plurality of packets in a specified sequence, wherein the device is operating under a protocol according to which the device is to send to a remote entity, respectively for each packet of the plurality, a positive acknowledgement (ACK) if the device receives the packet but a negative acknowledgement (NAK) if the device does not receive the packet; the device transmitting to the remote entity, respectively for each packet of the plurality, an ACK indicating that the device received the packet, regardless of whether the device actually received the packet, including transmitting to the remote entity an ACK respectively for at least one packet of the plurality that the device did not receive, whereby transmitting the ACK respectively for each packet helps avoid packet retransmission, while complying with the protocol; and the device replacing the at least one non-received packet with padding for processing by the device.
