    Abstract: Circuitry for use in a network controller comprises a processor and memory. The network controller is operable to control communications in a network comprising a plurality of devices connected via a shared coaxial cable. The circuitry is operable to maintain one or more data structures that hold per-sender-receiver-pair link parameters and per-sender-receiver-pair bandwidth grant status. The circuitry is operable to, in response to receipt of a reservation request on the shared coaxial cable, decide which one or more of a plurality of subbands and which one or more of a plurality timeslots to reserve for the transmission based, at least in part, on the per-sender-receiver-pair link parameters and the per-sender-receiver-pair bandwidth grant status in the one or more data structures. The circuitry is operable to generate a reservation grant message that indicates the decided one or more subbands and the decided one or more timeslots.

    Abstract: Methods and systems for providing reduced bandwidth acquisition latency may comprise communicating a reservation request for bandwidth allocation for devices operating under a wired network protocol, where the reservation request may be sent by wired network devices via a wireless network protocol over a wireless network. Bandwidth may be allocated in the wired network for the requesting devices by a network controller. Data may be communicated with the requesting devices via the wired network. The wired network communication protocol may comprise a multimedia over cable alliance (MoCA) standard. The wireless protocol may comprise an IEEE 802.11x standard, a Bluetooth standard, and/or any non-public network protocol. The communication of the reservation request via the wireless protocol may decrease a latency of the wired network. A medium access plan (MAP) may be generated by the network controller based on the reservation request and may comprise a bandwidth allocation for the requesting devices.

    Abstract: Systems and methods are provided for adaptive control of pre-distortion during signal transmissions. While applying pre-distortion during processing of an input signal for transmission, feedback data may be generated based on a plurality of feedback signals, and adjustments to the pre-distortion may be applied to the pre-distortion based on the feedback data. Each of feedback signals corresponds to a particular processing stage performed during the processing of the input signal. Generating the feedback data comprises applying adjustments to the plurality of feedback signals based on a type and/or a source of at least one feedback signal, with the adjustments comprising one or more of: applying a gain to one of the plurality of feedback signals; applying a delay to one of the plurality of feedback signals; and modifying a first one of the plurality of feedback signals based on a second one of the plurality of feedback signals.

    Abstract: Methods and systems are provided for band translation with protection. A signal processing circuitry (chip) may be configured to receive and process a plurality of input signals, and generate one or more output signals based on the plurality of input signals. The processing may comprise determining when including a component of a first input signal into at least one output signal would have an effect on a component of a second input signal that is also to be included in the output signal, and applying, based on the effect, one or more adjustments to processing of one or both of the first signal and the second signal to mitigate the effect before generating the output signal. In this regard, applying the one or more adjustments may comprise applying one or both of filtering and spectral inversion to one or both of the first signal and the second signal.

    Abstract: A network device comprising: a first connector for connecting to an external network from which data may be communicated using a first frequency band in accordance with a first communications protocol; a second connector for connecting to an on-premises network; and circuitry residing in a signal path between said first connector and said second connector. The circuitry may be operable to: permit a first portion of the first frequency band to pass from the first connector to the second connector; block a second portion of said first frequency band from passing from the first connector to the second connector; and communicate, via the second connector, signals that are normally communicated in frequency ranges not including the first frequency band, into the on-premises network using the first frequency band. The signals may include packets formatted in accordance with Multimedia over Coax Alliance (MoCA) standards.

The CMTS may assigning the modems among a plurality of service groups based on the SNR-related metrics.
