Abstract: Embodiments provide solutions to reduce power utilization (either at individual cable modems or in the overall network) in future cable modem networks. Particularly, embodiments seek to reduce power utilization at individual cable modems and in the overall network, by allocating upstream frequency bands and/or transmission modulation schemes among cable modems while accounting for cable loss experienced by individual upstream cable modem transmissions. According to embodiments, frequency spectrum and modulation scheme allocation techniques are provided to optimize power utilization and enable lower upstream transmission power by cable modems while maintaining similar signal strength of received signals or lower signal strength with reduced SNR requirements using lower capacity modulation at the headend.
Abstract translation: 实施例提供了在将来的有线调制解调器网络中降低功率利用（在单个电缆调制解调器或整个网络中）的解决方案。 具体地，实施例通过在电缆调制解调器中分配上行频带和/或传输调制方案，同时考虑各个上行电缆调制解调器传输所经历的电缆损耗，寻求降低各个电缆调制解调器和整个网络的功率利用率。 根据实施例，提供频谱和调制方案分配技术以优化功率利用并且通过电缆调制解调器实现较低的上行传输功率，同时在前端使用较低容量的调制来维持接收信号的相似信号强度或具有降低的SNR要求的较低信号强度。

Abstract: Embodiments include systems and methods for enabling a physical layer (PHY) link signaling channel between a network termination modem and a cable modem in a cable network. The PHY link signaling channel is embedded within the same multi-carrier channel as the data and enables PHY link up between the network termination modem and cable modem without involvement of higher layers (e.g., MAC). The PHY link signaling channel can be implemented in the downstream (from the network termination modem to the cable modem(s)) or in the upstream from a cable modem to the network termination modem. Embodiments are applicable to any known cable network, and particularly to cable networks implementing the DOCSIS and EPoC standards.

Abstract: Embodiments of a digital up-converter and an N-channel modulator are provided herein. The embodiments of the digital up-converter, in combination with the N-channel modulator, are capable of efficiently filling the spectrum of one or more RF signals with one or more types of information signals. For example, the digital up-converter can fill the spectrum of one or more RF signals with both broadcast and narrowcast video and data signals. In addition, the digital up-converter is capable of flexibly mapping the information signals to one or more channels of the one or more RF signals using a novel, three-level switching architecture.

Abstract: A method, system and computer program product to schedule transmissions in a two-tier network are provided. In an example, the system includes a Data Over Cable Service Interface Specification (DOCSIS) scheduler configured to generate a MAP message to allocate bandwidth and a first instance in time to a cable modem to transmit data to a branch node. The system further includes a MAP message translator coupled to the DOCSIS scheduler and configured to determine a second instance in time at which data from the cable modem arrives at the branch node and generate a GATE message that grants the branch node bandwidth to transmit the data received from the cable modem at the second instance in time to a headend node.

Abstract: A central entity and/or a remote device in a communication system are designed to address the problem of maintaining upstream synchronization in the remote device after loss of the downstream signal. One issue of particular importance is maintaining upstream transmissions from the remote device in an S-CDMA (or perhaps S-TDMA) mode that do not degrade performance of the communication system via poor upstream timing or a need for re-ranging. By providing novel functionality at the central entity for synchronizing first and second downstream signals and/or by providing novel functionality at the remote device for determining a symbol clock offset between a first terminated downstream signal and a second re-acquired downstream signal, embodiments of the present invention facilitate maintenance of synchronization through the loss of the downstream signal, thereby minimizing the need for re-ranging and avoiding poorly timed upstream bursts.
