Allocating orthogonal frequency-division multiple access (OFDMA) resources in ethernet passive optical network(PON) over coaxial (EPOC)
A method implemented in a Fiber Coaxial Unit (FCU) comprising receiving a plurality of Ethernet Passive Optical Network (EPON) report messages from a plurality of Coaxial Network Units (CNUs) across a coaxial network, receiving an EPON gate message comprising Time Quanta (TQ) information indicating an upstream transmission time grant for the FCU across the optical network, translating the TQ based upstream transmission time grants to OFDM resource block grants in a time domain and in a frequency domain across the coaxial network for each CNU based on the configurable constants, and transmitting an EPON over Coaxial (EPoC) gate message to each CNU, wherein each EPoC gate message comprises a CNU profile indicating the Orthogonal Frequency-Division Multiplexing (OFDM) resource block grants for the an associated CNU and a start time.
