摘要：
In wireless communication networks that use ARQ/HARQ feedback protocols, when a first device receives an apparent HARQ ACK from a second device, the first device may make a new transmission using a HARQ Channel ID whose previous usage was under conditions indicating a likelihood of error in the ACK. When the second device receives the new transmission, the reuse of that HARQ Channel ID in a new transmission rather than a retransmission lets the second device know that its previous NAK transmission was incorrectly received as an ACK.
