Claim:
A method for implementing hybrid automatic repeat request (H-ARQ)-assisted automatic repeat request (ARQ), the method comprising: determining that an H-ARQ negative acknowledgement (NACK)-to-positive acknowledgement (ACK) error has occurred with respect to a failed packet, wherein more than one packet is transmitted simultaneously and the H-ARQ NACK-to-ACK error indicator indicates H-ARQ NACK-to-ACK errors of more than one packet; determining whether or not to transmit an H-ARQ NACK-to-ACK error indicator, wherein the H-ARQ NACK-to-ACK error indicator is not transmitted on a condition that any of the number of retransmissions of the failed packet has reached a maximum retransmission limit, a maximum time for delivery of the failed packet has expired, or a lifespan of the failed packet has expired; and determining whether or not to transmit a local NACK.
