Abstract
The present invention relates to a communication controller (131; 132) and method for controlling communications between an access node (101; 102) and a plurality of remote communication units (211; 212) coupled to the access node via at least one wired transmission medium (20; 40). At least one communication unit (111, 211; 112, 212) of the access node and of the plurality of remote communication units is configured to operate in full-duplex mode according to a first full-duplex communication profile (OP1) when using a first subset of transmission resources (TSSET1; TONESET1) selected from a whole set of transmission resources available for communication over the at least one transmission medium, and according to a second full-duplex communication profile (OP2) when using a second non-overlapping subset of transmission resources (TSSET2; TONESET2) selected from the whole set of transmission resources. The first full-duplex communication profile includes first downstream and upstream transmit power profiles (PSDDS1, PSDUS1) to achieve first aggregate downstream and upstream data rates (DSMAX1, USMIN1; DSMAX2, USMIN2) over the at least one transmission medium, and the second full-du…
