摘要： 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-duplex communication profile includes second downstream and upstream transmit power profiles (PSDDS2, PSDUS2) to achieve second aggregate downstream and upstream data rates (USMAX1, DSMIN1; USMAX2, DSMIN2) over the at least one transmission medium distinct from the respective first aggregate downstream and upstream data rates. The present invention also relates to a so-configured full-duplex communication unit.

摘要： A vectoring controller for configuring a vectoring processor that jointly processes DMT communication signals to be transmitted over, or received from, a plurality of N subscriber lines according to a vectoring matrix. In accordance with an embodiment, the vectoring controller is configured, for given ones of a plurality of tones, to enable the given tone for direct data communication over a first set of N−Mk targeted lines out of the plurality of N subscriber lines, and to disable the given tone for direct data communication over a second disjoint set of Mk supporting lines out of the plurality of N subscriber lines, Mk denoting a non-null positive integer. The vectoring controller is further configured to configure the vectoring matrix to use an available transmit or receive power at the given tone over the second set of Mk supporting lines for further enhancement of data signal gains at the given tone over the first set of N−Mk targeted lines.

摘要： A network unit includes a non-linear precoder for jointly pre-processing transmit samples to be transmitted over respective communication channels for crosstalk mitigation. The non-linear precoder includes a first non-linear precoding stage configured to operate according to a first triangular precoding matrix and including a modulo function, followed by a second linear precoding stage configured to operate according to a second precoding matrix. The network unit further includes a first pilot signal generator configured to generate first pilot signals for pre-processing by the second precoding stage only to yield partially-precoded pilot signals for further transmission over the respective communication channels, and a controller configured to update the second precoding matrix based on first error measurements performed during the transmission of the partially-precoded pilot signals over the respective communication channels while keeping the first precoding matrix unaltered.

摘要： In one embodiment, the method includes determining, at an access node, a precoder matrix for precoding transmission from the access node to a plurality of downstream devices over a plurality of lines. The plurality of lines include high power lines and low power lines. The high power lines are in active communication and transmit more symbols per frame than the low power lines. The method further includes precoding a signal vector using the precoder matrix regardless of the symbols the signal vector is sending over the low power lines. Here, the determining determines the precoder matrix such that the precoding does not mitigate the cross-talk effect the high power lines have on the low power lines. The method also includes transmitting over the plurality of lines based on the precoded signal vector.
