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

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

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 and devices are discussed. A device configured to operate in a network comprises communication circuitry and a transceiver.

An apparatus for pilot tone synchronization in point-to-multipoint (P2MP) communication is described, including a transceiver configured to send a downstream transmission including pilot tones to one or more customer premises equipments (CPEs) in a P2MP group. A method for pilot tone synchronization in point-to-multipoint (P2MP) communication is described, including sending a downstream transmission including pilot tones to one or more customer premises equipments (CPEs) in a P2MP group.

Method and system for pilot tone synchronization in point-to-multipoint systems

A system for a fiber-optic network includes a transceiver. The transceiver includes a fiber-optic interface unit and a host unit. The host unit includes a low-complexity error correction decoder and a high-complexity error correction decoder. One or both from the low-complexity error correction decoder and the high-complexity error correction decoder are selected to decode input data from the fiber-optic interface unit, the input data including codewords.

PMD-to-TC-MAC interface with 2-stage FEC protection

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.

Partial echo cancellation duplexing

Examples relate to a transmit apparatus, a receive apparatus, a method for transmitting, a method for receiving and computer readable storage media for transmitting and/or receiving in a communication network. A transmit apparatus for transmitting discontinuous time-frequency operation, DTFO, signals in a communication network comprises a transmitter configured to transmit a DTFO signal comprising monitoring symbols and regular DTFO symbols in the communication network. The apparatus further comprises processing circuitry, which is coupled to the transmitter and configured to generate at least one monitoring symbol for transmission by the transmitter if a time gap of the DTFO signal between two sub-sequent regular DTFO symbols exceeds a first time threshold, wherein the at least one monitoring symbol is configured to enable frequency-domain equalizer, FEQ, adjustment at a receiver of the DTFO signal; and generate a training sequence for transmission by the transmitter if a time period between a last transmission of a monitoring or regular DTFO symbol and a sub-sequent transmission of a DTFO symbol exceeds a second time threshold, the training sequence comprising at least one monitoring symbol preceding a regular DTFO symbol.

Apparatus, method and non-transitory, computer readable storage media for transmitting and receiving discontinuous time-frequency operation signals in a communication network

A device for transmitting and receiving on a coaxial cable or twisted pair cable is disclosed. The device includes a plurality of transceivers for transmitting signals to, and receiving signals from, at least one customer premise equipment (CPE) via a plurality of channels. The plurality of channels may be formed by using a plurality of twisted pairs cable or by using a plurality of frequency bands on a coaxial cable or a twisted pair. The device may also include at least one canceller for cancelling echo and/or crosstalk on at least one channel, and a processor configured to allocate to a single CPE multiple frequency bands on a single cable or multiple lines among a bundle of twisted pairs. The device may work for both coaxial cables and twisted pair cables and support for unified use of channel bonding in a frequency domain and a spacial domain.

A PLC modem (-) is prompted to increase, starting from a predetermined minimum transmit power, a transmit power of data transmission on a PLC channel () at a given time or time period defined with respect to a mutual time reference of a DSL channel () and the PLC channel (). A DSL modem () is prompted to measure a signal-to-noise value at the given time or time period defined with respect to the mutual time reference. Mitigation of interferencebetween the PLC channel () and the DSL channel () becomes possible.
