In a communication device, a multi-carrier signal with at least one group of signal carriers is received from a communication connection. For each of the signal carriers, at least one individual error value is evaluated or generated. From the individual error values, a combined error value is evaluated or generated. The combined error value is transmitted on a backchannel of the communication connection.

One embodiment relates to a communication system. The communication system includes a central node that is coupled to a communication channel and configured to individually communicate with a number of network nodes over a frequency range. One of the network nodes can identify a common frequency band that is within the frequency range and on which the central node and network nodes can transmit a signal. Other methods and systems are also disclosed.
