Patent ID: 7760755

Claim:
A device including: a controller to set a request-to-send threshold of a request-to-send protection mechanism to a first value for transmission of a first plurality of packets without request-to-send protection, and to determine a first packet-error-rate based on a relation between a number of the first plurality of packets and a number of received acknowledgements to the first plurality packets, wherein, if the first packet-error-rate is greater than a packet-error-rate threshold, the controller is to decrease the request-to-send threshold to a second value to protect the transmission of all packets of a second plurality of packets, and wherein the controller is to determine a second packet-error-rate based on a relation between a number of the second plurality of packets and a number of received acknowledgements to the second plurality packets, and to adjust the request-to-send threshold based on the second packet-error-rate.
