System and method for full duplex using code multiplexing

A system for duplex communication in a network, comprising:

• a processing node;
• and
• a processor coupled to the processing node, the processor being configured to perform operations comprising:
• setting an overlap threshold;
• determining that a first access node and a second access node utilize a same frequency band;
• determining an overlap amount between a first time division duplex (TDD) allocation corresponding to the first access node and a second TDD allocation corresponding to the second access node, wherein the first and second TDD allocations comprise asynchronous allocations and wherein overlap occurs in the asynchronous allocations where the first access node and the second access node are utilizing the same frequency band in a same link direction at a same time;
• comparing the overlap amount to the overlap threshold;
• and
• in response to a determination that the overlap amount exceeds the overlap threshold, instructing the first access node to multiplex a downlink communication signal with an orthogonal code for communications between the first access node and a plurality of wireless devices connected to the first access node, wherein the downlink communication signal is multiplexed with the orthogonal code for a predetermined period of time before the multiplexing with the orthogonal code is stopped.
