Patent ID: 8891605

Claim:
A method comprising: determining, at a first device, signal-to-noise (SNR) characteristics of received signals at various times during a powerline cycle, including a first SNR measurement at a first portion of the powerline cycle and a second SNR measurement at a second portion of the powerline cycle; determining, at the first device, line cycle adaptation periods within the powerline cycle based at least in part on the SNR characteristics, wherein determining the line cycle adaptation periods includes determining a line cycle adaptation period boundary between the first portion of the powerline cycle and the second portion of the powerline cycle when a difference between the first SNR measurement and the second SNR measurement exceeds a threshold amount, the line cycle adaptation period boundary associated with an end of a first line cycle adaptation period and a beginning of a second line cycle adaptation period; and coordinating the line cycle adaptation periods with a second device such that subsequent transmissions from the second device are in accordance with line cycle adaptation properties specific to each line cycle adaptation period.
