Systems and methods to transmit information among a plurality of physical upstream channels
View Patent ↗A communication system includes a supervisory node (e.g., a headend) and one or more remote nodes (e.g., cable modems). The supervisory node or a remote node monitors a characteristic associated with the communication system. Remote node transmits an upstream communication among a plurality of physical upstream channels based on the characteristic. The average transmit power used to transmit the upstream communication among the plurality of physical upstream channels is no greater than the average transmit power that would be necessary to transmit the upstream communication using a single physical upstream channel at a lower data rate.

transmit a second portion of data that includes more data than the first portion of data, using a same amount of power as used to transmit the first portion of data, via a second at least one of the plurality of communication channels that includes a different number of channels than the first at least one of the plurality of communication channels and that includes at least one more channel than the first plurality of communication channels and based on a second power that is different than the first power.
8. The apparatus of claim 7 further comprising:
a cable modem, wherein the at least one additional apparatus is a cable modem termination system (CMTS).
9. The apparatus of claim 7 further comprising:
a cable modem termination system (CMTS), wherein the at least one additional apparatus is a cable modem.
10. The apparatus of claim 7 , where the second at least one of the plurality of communication channels to support a different data rate than the first at least one of the plurality of communication channels.
11. The apparatus of claim 7 further comprising:
when the at least one communication interface configured to transmit the second portion of data via the second at least one of the plurality of communication channels, the apparatus configured to lower a number of bits per symbol within the first at least one of the plurality of communication channel.
12. The apparatus of claim 7 , wherein the second at least one of the plurality of communication channels to support a different number of bits per symbol than the first at least one of the plurality of communication channels.
13. The apparatus of claim 7 further comprising:
the at least one communication interface configured to transmit a third portion of data via a third at least one of the plurality of communication channels that includes a different number of channels than the second at least one of the plurality of communication channels wherein, the third at least one of the plurality of communication channels support a different number of bits per symbol than the second at least one of the plurality of communication channels.
14. The apparatus of claim 7 further comprising:
a communication device that is operative within a cable communication system that includes at least one of a cable modem, a cable modem termination system (CMTS), and a cable headend.
15. A method for execution by a communication device, the method comprising:
operating at least one communication interface to support communication with at least one additional communication device via at least one of a plurality of communication channels;
