    摘要： A system and method for continuing a communication link while maintaining visibility in visible light communication. A frame is transmitted by a sender for establishing a communication link before data transmission to a receiver by a sender. A receiver sends a response frame that reports on establishment of the communication link prior to data transmission by the sender. A data frame containing information is transmitted by the sender to the receiver. An acknowledgment frame is transmitted to the sender in response to the data frame. A disconnect frame is transmitted by the sender which is acknowledged by the receiver. A visible sequence is transmitted during a time period when the sender and the receiver do not transmit respective frames for communication to maintain visibility between two devices that may be communicating otherwise by, for example, infrared communication.

    摘要： A method and apparatus for arranging communication links in visible light communication increases the user visibility of the system. The method includes the steps of: (a) synchronizing, by a visible light communication (VLC) exchange identification (XID) frame, (b) transmission timing of a primary device and a secondary device in an allocated time slot, and securing time so as to allow the primary device and the secondary device to perform an operation required for transmitting data; (c) transmitting an XID command frame from the primary to the secondary device and (d) transmitting an XID response frame from the secondary receiving the XID command frame to the primary; and (e) filling remaining space of the allocated time slot with a visibility field so as to increase visibility of the remaining space of the allocated time slot after receiving the XID command frame or the XID response frame.

    摘要： A method for communication link connection in a data transmission between devices using visible light communication (VLC) that can provide a visible indication prior to establishing a communication link between the devices. The method includes activating a VLC mode by a first VLC apparatus in order to transmit the data; scanning other apparatuses to establish a communication link with a second VLC apparatus; requesting a communication link to the second VLC apparatus in order to transmit the data; and receiving a response, indicating whether data can be received from the second VLC apparatus, and establishing communication link connection. A user can easily recognize the visual indication before the establishment of the communication link, providing an opportunity for the user to arrange the apparatus for optimal communication distance/angle from another device, and for a status of the communication.
