Abstract: Energy efficient Ethernet with asymmetric low power idle. Low power idle mode is typically leveraged when both direction of a link do not have data traffic to transmit. Such a requirement reduces the application of low power idle due to the frequent existence of data traffic in only one direction. An asymmetric low power idle mode enables reduction in power consumption and signal emissions even when one direction has data traffic to transmit.

Abstract: A communication device and methods are disclosed. A first throughput is calculated when a current modulation scheme and a current encoding rate is changed, and a second throughput is calculated when a current retransmission unit is changed. The current modulation scheme and the current encoding rate are changed to provide a changed modulation scheme and a changed encoding rate, if the first throughput is greater than or equal to the second throughput when prescribed conditions are met. The current retransmission unit is changed to provide a changed retransmission unit, if the first throughput is less than the second throughput. Information is transmitted to a communication device of a communication partner based on the changed modulation scheme, the changed encoding rate, and the changed retransmission unit.
