Abstract

A method implemented by a cable modem of a cable network includes sending an upstream test signal during at least one frequency division duplex minislot assigned to the cable modem, receiving other upstream test signals from other cable modems, measuring interference in each received test signal from the other cable modems, and reporting the interference measurement for each received test signal to a cable modem termination system.
