Abstract: The present technology relates to a reception device, a reception method, a transmission device, and a transmission method, which are capable of implementing a high transmission rate by effectively utilizing a frequency band in channel bonding. A reception device receives a plurality of divisional streams obtained by distributing baseband (BB) frames of a BB stream which is as a stream of BB frames to a plurality of data slices and reconstructs an original BB stream on the basis of reconfiguration information which is in included in transmission control information and used for reconstructing the original BB stream from the plurality of divisional streams transmitted through the non-neighboring frequency bands when the plurality of divisional streams are transmitted through non-neighboring frequency bands. The present technology can be applied to, for example, channel bonding such as PLP bundling.

Abstract: A signal is transmitted at a high speed in a direction opposite to a transmitting direction of a main large-capacity channel.A first transmitting unit transmits a first signal including a clock component to an external device through a transmission path as a differential signal. A second transmitting unit superimposes a second signal including a clock component on the transmission path as an in-phase signal to transmit to the external device. A state notifying unit communicates with the external device through a pair of differential transmission paths included in the transmission path and notifies the external device of a connection state of its own device by a DC bias potential of at least one of the pair of differential transmission paths.

Abstract: Circuits and methods are disclosed for low-skew bonding of a plurality of data channels into a multi-lane data channel. In one embodiment, phase-measuring first-in first-out buffer circuits buffer pre-buffer parallel data signals and generate phase-measurement signals. A channel-bonding control circuit receives the phase-measurement signals and generates bit-slip control signals. Transmission bit-slip circuits slip integer numbers of bits based on the bit-slip control signals. Bypass registers may be used when the integer number of bits is greater or equal to the parallel width of a lane. In another embodiment, the channel-bonding control circuit receives the phase-measurement signals from the phase-measuring FIFO buffer circuits and generates clock-slip control signals. Clock slip circuits controllably slip parallel clock signals by integer numbers of unit intervals of a serial clock signal. Various other aspects, features, and embodiments are also disclosed.

Abstract: A communication method is provided for a communication system comprising a transmitter and a receiver. The method involves communicating data from the transmitter to the receiver over a banded communication channel. The method comprises: applying a forward error correction, FEC, code to data to be transmitted to obtain FEC-encoded data; assigning the FEC-encoded data into a plurality of sub-channels; modulating the data from each of the plurality of sub-channels into a corresponding one of a plurality of sub-bands, the plurality of sub-bands having spaced apart center frequencies; and concurrently transmitting the data from the plurality of sub-bands onto a banded communication channel, the banded communication channel comprising one or more pass-bands and one or more stop-bands.

Abstract: A system for reducing latency in a networking application includes a first clock domain operating at a first clock frequency, where a media access control (MAC) sublayer sends data to a physical coding sublayer (PCS) utilizing the first clock domain. The system also includes a second clock domain operating at a second clock frequency, where data is transmitted on one or more physical medium attachment (PMA) lanes utilizing the second clock domain, and where the first clock frequency and the second clock frequency have a fixed ratio. Data is transmitted from the first clock domain to the second clock domain without buffering the data.

Abstract: A method includes dividing, at a cable modem termination system, a transmit stream into multiple data streams. The multiple data streams include a first data stream and a second data stream. Each of the multiple data streams has a lower bit rate than a bit rate of the transmit stream. The method includes transmitting, via the cable modem termination system, the first data stream over at least a first channel of a group of channels. The method also includes transmitting, via the cable modem termination system, the second data stream over at least a second channel of the group of channels. The group of channels supports traffic to a plurality of destinations. The first channel and the second channel are frequency-division multiplexed channels.
