Abstract: A method and an apparatus for retransmitting data of a wireless local area network system using a visible light communication is provided to rapidly retransmit data in an instantaneous data transmitting/receiving fail between an access point and a mobile node. A mobile node searches a fast feedback slot allocated for retransmission information in a frame in case an instantaneous data transmitting/receiving fail is generated(330). The mobile node selects one mini slot among mini slots included in the fast feedback slot in case the fast feedback slot exists(350). The mobile node transmits a fast feedback message including information for retransmitting with a selected mini slot to the access point(360).

Abstract: A method for steadily changing a duplex mode in a wireless lan system using visible light communications is provided to support a mobile node using full-duplex method and half-duplex method. It determines whether the change of the duplex mode is necessary by comparing bit error probability with predetermined target bit error probability when transmitting between an access point and a mobile node(401-404). If the change of the duplex mode is needed, the specific time clot within a frame is allocated as a test slot(405-412). The test slot is changed in a new transmitting/receiving method if the bit error probability is lower than the target error probability(413-418).
