Abstract
A method, node, and system are provided that overcome problems with using inaccurate estimates of a current round trip time RTT for verifying the ACK/NACK information received in an ACK/NACK report, e.g., a piggy-backed ACK/NACK (PAN). This is accomplished by de-coupling the RTT from the ACK/NACK analysis performed in the sending node that receives the ACK/NACK report. As a result, unnecessary re-transmissions are avoided, communication delays are decreased, and spectrum and other system resources are used more efficiently.
