A multi-carrier transmitter apparatus is disclosed. The apparatus includes an outer encoder, a shell mapper and an inner encoder. The outer encoder is configured to receive a signal, perform error correction using an outer code on the received signal and generate an outer encoder signal. The shell mapper is configured to perform constellation shaping on a subset of bits from the outer encoder signal and generate one or more constellation shaping bits. The inner encoder is configured to perform inner error correction/encoding using an inner code on a second subset of bits from the outer encoder signal and generate an inner correction signal.

Capacity achieving multicarrier modulation and coding systems and methods

An apparatus for a wired communication link is provided. The apparatus includes transmit circuitry for transmitting downstream data over the wired communication link during a frame for full duplex data transmission. The frame comprises a first subframe and a second subframe for downstream data transmission. The first subframe coincides in time with a third subframe of the frame for upstream data transmission, wherein the second subframe coincides in time with a fourth subframe of the frame for upstream data transmission. The first subframe and the fourth subframe are priority subframes. The second subframe and the third subframe are non-priority subframes. Each of the first subframe and the fourth subframes comprises a respective discontinuous operation interval.

Techniques discussed herein can facilitate handshake procedures for Point-to-Multipoint (P2MP) communication in connection with various DSL (Direct Subscriber Line) technologies. Various embodiments can employ different methods of separation of signaling to arrange P2MP handshake procedures based on existing Point-to-Point (P2P) handshake procedures. Example embodiments can employ one of separation in frequency, separation in time, or separation in transmission power level.

Handshake operation in point-to-multipoint access from distribution point

Techniques for implementing timesharing in discontinuous systems, for example to implement low power modes, are discussed. In some embodiments, a set of bit loading tables is determined in advance, and bit loading tables are then selected based on which lines are transmitting and which are quiet.

Timesharing for low power modes

Representative implementations of devices and techniques provide communication between networked nodes operating on a communication network medium. In an implementation, a node generates a broadcast frame that includes at least a preamble and a payload. The preamble of the broadcast frame may include auxiliary information. The auxiliary information may be associated with one or more symbols of the preamble. The auxiliary information may contain power boost information.

Methods, circuitries, and systems for transmitting data upstream between a first device and a second device and downstream between the second device and the first device are disclosed. A method includes determining an upstream crosstalk effect for an upstream channel and determining a downstream crosstalk effect for a downstream channel. The crosstalk effect includes near end crosstalk from a third device that is non-co-located with respect to the first device and the second device. A data rate of an upstream transmission or downstream transmission is adjusted based on the upstream crosstalk effect and the downstream crosstalk effect.
