System and method for managing interference in Li-Fi communication networks

Abstract:

A method and system for managing interference between a set of Light Fidelity (Li-Fi) access points is disclosed. The method includes receiving a plurality of uplink data frames. Each of the plurality of uplink data frames includes a response that includes one of an Acknowledgement (ACK) and a Negative Acknowledgment (NACK) for the associated downlink test frame and a Channel Quality Indication (CQI) for the associated Li-Fi access point. The method further includes detecting presence of the User Equipment (UE) in an interference region of the set of Li-Fi access points. The method includes attaching the UE with a first Li-Fi access point having the highest CQI and scheduling data transmission from the set of Li-Fi access points in a mutually exclusive time slot. The UE accepts data received from the attached Li-Fi access point and drops data received from remaining set of Li-Fi access points.
