Full duplex resource allocation in cable network environment

A method, comprising:

• implementing, by a media access control (MAC) scheduler in a cable network, a transmission-reception (T-R) coordination scheme among a plurality of cable modems in the cable network, wherein according to the T-R coordination scheme, the cable modems are categorized into interference groups, wherein no cable modem of any one interference group transmits upstream in a frequency range simultaneously as another cable modem in the same interference group receives downstream in the frequency range, facilitating full duplex communication in the cable network across the frequency range;
• assigning one or more of the interference groups to at least one transmission group based upon predetermined criteria;
• and
• determining an upstream bandwidth constraint and downstream bandwidth constraint for the at least one transmission group, wherein the upstream bandwidth constraint and downstream bandwidth constraint is implemented by proportionally modifying an allocated upstream bandwidth and an allocated downstream bandwidth for the at least one transmission group to require that the sum of the allocated upstream bandwidth and allocated downstream bandwidth does not exceed a spectrum capacity for the at least one transmission group.
