METHOD AND APPARATUS FOR INDICATION STATUS OF MOBILE NODE IN WIRELESS LOCAL AREA NETWORK USING VISIBLE LIGHT COMMUNICATION

摘要

A method for displaying the state of a mobile node in a wireless LAN system using visible light communications and an apparatus therefore are provided to allocate the state display resource of a mobile node for handshaking and to improve the transmission of uplink data. A time slot in an access point is allocated as unassigned slot for state indication of a handshake node. The time slot is allocated to a retention slot capable of data transfer of uplink. The unassigned slot or the visible light signal indicating the state information of the handshaking mobile node in the retention slotted section is transmitted. The visible light signal indicating the state information of the mobile node indicates the status information of the mobile node.
