Patent ID: 8433967

Claim:
A method for determining a retransmission threshold condition in a selective repeat type, automatic repeat request (ARQ) wireless communication system, comprising: receiving a set of negative acknowledgement (NACK) sequence numbers (SN) corresponding to a set of non-received data packets, wherein the set of NACK SNs comprises a lowest NACK SN and a highest NACK SN; determining a first variable corresponding to a position of the lowest NACK SN with respect to a previously received set of NACK SNs; determining a second variable corresponding to a difference between the lowest NACK SN and the highest NACK SN; generating an array based on the first and second variables, wherein one or more elements of the array correspond to a maximum number of retransmissions associated with each non- received data packet; generating an index value based on the one or more elements; comparing the index value with a threshold value to determine the retransmission threshold condition; and continuing retransmission of the set of non-received data packets based on the retransmission threshold condition.
