Method and apparatus of building a coaxial convergence layer in ethernet passive optical network (PON) over coaxial network (EPoC)

摘要

An apparatus comprising a data framer comprising a physical layer protocol stack comprising a coax convergence layer, a coax framing layer next to the convergence layer, wherein the coax framing layer is configured to decompose and assemble data packets in a coax network, a coax coding layer next to the coax frame layer, wherein the coax coding layer is configured to protect the coax transmissions from impairments, a coax modulation layer next to the coax coding layer, wherein the coax modulation layer is configured to modulate the data according to a coax physical layer (PHY), and a radio frequency layer next to the coax modulation layer and configured to interface to an electrical medium for a coaxial network.

1. A method comprising:
receiving a gate message from an Optical Line Terminal (OLT), wherein the gate message comprises a Logical Link Identifier (LLID), a grant start time, and a grant length; calculating an uplink symbol offset based on the grant start time; calculating an uplink symbol number based on the uplink symbol offset; searching empty Physical Resource Blocks (PRB) in the uplink symbol number in an uplink PRB table; and allocating uplink PRBs to the LLID according to the grant length specified in the gate message.
