Abstract
Devices, systems and methods for adaptively associating a percentile value to each of a plurality of subcarriers at which a cable modem communicates data, the percentiles value used to respectively determine an aggregated RxMER value for each subcarrier. The aggregated RxMER values for the subcarriers may be used to determine and assign one or more bitloading profiles to the cable modem.

1-35. (canceled)
A method comprising:
- assigning each of a plurality of cable modems to its own cluster;
- and
- incrementally reducing the number of clusters by sequentially combining two said clusters until the number of clusters is reduced to a desired number;
- determining a set of bitloading profiles using the desired number of clusters;
- allocating the bitloading profiles among the plurality of cable modems;
- and
- communicating with the cable modems using the allocated bitloading profiles.

A CMTS configured to:
- assign each of a plurality of cable modems, each communicatively coupled to the CMTS, to its own cluster;
- incrementally reduce the number of clusters by sequentially combining two said clusters until the number of clusters is reduced to a desired number;
- and
- determine a set of bitloading profiles using the desired number of clusters;
- allocate the bitloading profiles among the plurality of cable modems;
- and
- communicate with the cable modems using the allocated bitloading profiles.
