Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a method, device and equipment for reporting and receiving visible light filtering capability. Background Art

[0002] Visible light wavelength division multiplexing technology is currently a popular multiplexing modulation technology in the visible light field. The main principle is to use light of different wavelengths from a multi-color light source to carry multiple data streams at the same time to increase the system data rate. Different data can be independently modulated by different primary color LEDs and signals of different bands can be separated by filters at the receiving end to achieve wavelength division multiplexing gain.

[0003] like Figure 1 As shown, for the transmitting end, three different signals are amplified by the driver and then loaded onto LED chips of different colors through the Bias-Tee (bias tee). Then the light beams of different colors are coupled in space to generate white light and transmitted in space.

[0004] For the receiving end, after the lens focuses and the filter selects the wavelength, the receiving circuit collects the signal and performs back-end processing.

[0005] like Figure 2 As shown, the wavelength ranges of the currently commonly used RGB three-color filters are 380nm-480nm, 480nm-580nm, and 580nm-780nm respectively.

[0006] For visible light wavelength division multiplexing technology, the transmitter uses light beams of different colors to transmit different data streams, and the receiver is equipped with filters to select the wavelength of the corresponding light beam for signal reception.

[0007] In actual networking, the receiving end (user) configures different types of filters, and has different abilities to receive light beam colors. Without knowing the receiving end's receiving ability, the sending end cannot use the light color within the receiving end's corresponding ability range for data transmission.

[0062] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0063] like Figure 3 As shown, an embodiment of the present invention provides a visible light filtering capability reporting method, which is applied to a receiving end device, and the method includes:

[0064] Step 31: Before starting to transmit data through the light beam, report the visible light filtering capability of the receiving end device to the transmitting end device.

[0065] In this embodiment of the present invention, the light filtering receiving capability supported by the receiving end can be reported with the assistance of a wireless communication network, and the receiving end can use light colors within the corresponding capability range for data transmission, thereby improving transmission efficiency. The wireless network here may include 4G LTE, 5G, or future 6G and other wireless technology-based networks.

[0066] In an optional embodiment of the present invention, step 31 may include:

[0067] Step 311: reporting the visible light filtering capability of the receiving end device to the sending end device based on the request of the sending end device; or,

[0068] Step 312: Actively report the visible light filtering capability of the receiving end device to the transmitting end device.

[0069] Optionally, step 311 may include:

[0070] Receive a visible light filtering capability reporting request sent by a transmitting device;

[0071] Report the visible light filtering capability of the receiving end device to the sending end device according to the visible light filtering capability reporting request.

[0072] When this embodiment is implemented, Figure 4 As shown, the user (receiving device) accesses the wireless base station (forming a network with a base station with visible light transmission capability) through wireless technology. When the user (receiving device) has a large number of downlink service needs, the base station hopes to use visible light technology to enhance downlink transmission. The base station triggers the user to report the visible light receiving capability, and the user reports the capability through wireless uplink transmission.

[0073] In an optional embodiment of the present invention, step 312 may include:

[0074] Monitor the broadcast signals transmitted by the time-frequency resources reserved by the visible light access point on the spectrum of each color;

[0075] When the visible light filtering capability that meets its own requirements is found, the visible light filtering capability of the receiving end device is reported to the sending end device.

[0076] When this embodiment is implemented, Figure 5 As shown, the visible light access point reserves specific time-frequency resources on the spectrum of each color for transmitting broadcast signals. The user (receiving device) monitors the broadcast signal of the corresponding color light. When the user finds a broadcast signal that meets his or her filtering capability, he or she actively reports the filtering capability through the wireless base station in the same networking.

[0077] In an optional embodiment of the present invention, the visible light broadcast channel is a fixed time-frequency domain, spatial domain, and code domain resource reserved by a visible light access point; when a user reports using a wireless base station, the uplink transmission resource used for reporting information can be determined by the following two methods:

[0078] Step 313, when a broadcast channel of a visible light access point is found, the uplink resource reserved by the transmitting end device is used to report the visible light filtering capability of the receiving end device; or,

[0079] Step 314: When a broadcast channel of a visible light access point is found, the visible light filtering capability of the receiving device is reported by using the uplink resources allocated by the transmitting device based on the uplink scheduling request of the receiving device.

[0080] Wherein, when step 313 is implemented specifically, Figure 6 As shown, the wireless base station reserves specific uplink resources for the user. When the user finds the broadcast channel of the visible light access point and hopes to report the capability, the user directly reports the capability in a grant-free manner.

[0081] When step 314 is implemented specifically, Figure 7 As shown, when the user finds the broadcast channel of the visible light access point and wants to report its capabilities, it sends an uplink scheduling request (SR) to the wireless base station. The wireless base station allocates uplink scheduling resources to the user through downlink control signaling (DCI), and the user transmits the capability report on the specified resources.
