摘要:
A method, apparatus, and a non-transitory computer readable storage medium for supporting visible light communication (VLC) exchanges bitmaps for capabilities field exchange in a media access control (MAC) layer during link establishment and association with other VLC-enabled devices. An aggregation bitmap is generated to indicate whether a visible light communication (VLC) transmitter of a first device uses at least one aggregated band that comprises multiple active frequency bands. The aggregation bitmap is transmitted in a capabilities information exchange (CIE) signal to a second device. A guard bitmap that identifies a set of guard frequency bands is also generated and transmitted in the CIE signal. Each guard frequency band indicates leakage transmission from the VLC transmitter.
