Embodiment Construction

[0016] The inventive concepts will be described more fully hereinafter with reference to the accompanying drawings, in which examples of embodiments of the inventive concepts are shown. However, inventive concepts may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the various inventive concepts to those skilled in the art. It should also be noted that these embodiments are not mutually exclusive. Components from one embodiment may by default be present / used in another embodiment.

[0017] Embodiments of the present disclosure relate to improvements in how to control communication between a VLC AP and a UE when the VLC AP has at least partially overlapping communication coverage areas. Although light sources for VLC APs may have beams configured to provide better defined communication ...

Abstract

A method by a coordinating node for controlling communication between a visible light communication VLC access point AP (130) and a user equipment UE (108) is disclosed. The method includes identifying an occurrence of an event related to operation of a first VLC AP (130). The method also includes determining that the second VLC AP (130) and the third VLC AP (130) each have a communication coverage area at least partially within a communication coverage area of ​​the first VLC AP (130), in response to the occurrence of the identification event. Then, the method controls the second VLC AP (130) and the third VLC AP (130) in response to the determination to avoid them from interfering with the first VLC AP (130) with the second VLC AP (130) or the third VLC AP (130). Communication between any UE (108) within the common communication coverage area of ​​). The relevant coordinating nodes are disclosed.

Description

technical field [0001] The present disclosure relates generally to networking systems and methods, and more particularly to visible light communication (VLC) systems and associated access points (APs). Background technique [0002] With the explosion of smartphones, tablets, laptops, and other user equipment (UE) in enterprise (e.g., bring your own device or BYOD) and guest account scenarios, the demand for wireless bandwidth in high-density UE environments Demand keeps growing. Traditionally, WLAN (also known as Wireless Fidelity (WiFi)) is the primary means of connectivity for UEs. WLANs are generally defined in IEEE802.11 and its variants. As demand grows exponentially with the proliferation of such devices, the wireless spectrum necessary for communication between WiFi / WLAN access points (APs) and UEs is becoming increasingly scarce. [0003] Deploying more WiFi / WLAN access points (APs) may not be the right solution due to already high levels of interference from comp...
