Abstract: The techniques described herein relate to methods, apparatus, and computer readable media configured to schedule individual orthogonal frequency-division multiple access (OFDMA) resources on an upstream channel to serve a data transmission request from a downstream device. A schedule for a set of available resources on the upstream channel to serve the data transmission request is generated, based on a dynamic bit loading profile, including generating data indicative of a first bit loading profile for a first set of resources from the set of available resources for a first burst, and data indicative of a second bit loading profile for a second set of resources from the set of available resources for a second burst. The schedule is transmitted to a downstream device, such that the downstream device is configured to encode the first burst using the first bit loading profile and the second burst using the second bit loading profile.

Abstract: Systems and methods are provided for performing fiber node splits in DOCSIS cable systems by performing remote modulation and/or demodulation in the fiber node. In the downstream direction, a high-speed digital fiber optic interface can be used to send data from the CMTS to the fiber node, which then modulates the data onto separate downstream interfaces for subsequent distribution of the downstream data to CMs and/or STBs. In the upstream direction, different upstream interfaces from the CMs and/or STBs may be demodulated into digital streams which can then be combined into a single, time division multiplexed digital stream that is transmitted to the CMTS. As such, the modulation and demodulation functions are performed remotely in the fiber node instead of at the CMTS.
