Patent ID: 8521034

Claim:
For use in a visible light communication (VLC) network, a method for device association, interference mitigation and channel selection, the method comprising: transmitting on every one of a plurality of supported color channels of a first device to estimate an ambient interference on each supported color channel; collecting a transmit channel quality index (TX CQI) report, wherein the TX CQI report includes a TX CQI for each of a plurality of receiving color channels of a second device; selecting one of the supported color channels of the first device to be used as a transmit communication channel by the first device based on the TX CQI; receiving a transmission from the second device on at least some of the supported color channels of the first device, where a number of the color channels on which the transmission is received is less than or equal to a number of the supported color channels of the first device; calculating a receive channel quality index (RX CQI) for each of the color channels of the first device on which the transmission was received; selecting at least one of the color channels of the first device on which the transmission was received to be used as a receive communication channel by the first device based on the RX CQI; and reporting the at least one receive communication channel to the second device in the VLC network.
