Abstract
Link adaptive retransmission techniques are provided for use in connection with wireless communications between a first wireless communication device and a second wireless communication device. The first wireless communication device generates M packet error information values for the transmit session of a packet based on whether an acknowledgment message or a non-acknowledgment message is received from the second wireless communication device for a transmission and for previously sent transmissions even if less than M transmissions are sent by the first wireless communication device to the second wireless communication device upon completion of the transmit session. The first wireless communication device computes a retransmission fading margin based on the M packet error information values, from which an effective carrier-to-interference-plus-noise ratio is derived for selection of a modulation scheme.
