Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a link recovery processing method, device and equipment. Background Art

[0002] With the development of technology, visible light wavelength division multiplexing technology has become a popular multiplexing modulation technology in the visible light field. Its 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 light emitting diodes (LEDs) of different primary colors and signals of different wavelengths can be separated by filters at the receiving end to achieve wavelength division multiplexing gain.

[0003] For wavelength division multiplexing technology, the transmitter uses light beams of different colors to transmit different data streams, and the receiver is equipped with a filter to select the wavelength of the corresponding light beam for signal reception. In actual networking, the user's link channel situation may change due to factors such as actual environmental light pollution and user location movement. When the specific color light beam currently used by the user can no longer communicate stably due to environmental changes, the user's data transmission will be interrupted. At this time, a fast link recovery process is required to maintain stable communication.

[0004] However, with the current fast link recovery method based on visible light networks, the sender and receiver cannot know in advance when the other party will send a fast link recovery (FLR) signal or FLR RSP (Response). Therefore, the devices at both ends must perform blind detection of FLR / FLR RSP on each color light beam in real time, which increases the processing complexity of the device and increases power consumption.

[0102] In order to make the technical problems, technical solutions and advantages to be solved by the present invention more clear, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0103] It should be understood that the references to "one embodiment" or "an embodiment" throughout the specification mean that the specific features, structures, or characteristics associated with the embodiment are included in at least one embodiment of the present invention. Therefore, the references to "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. In addition, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0104] In various embodiments of the present invention, it should be understood that the size of the serial numbers of the following processes does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0105] Additionally, the terms "system" and "network" are often used interchangeably herein.

[0106] In the embodiments provided in the present application, it should be understood that "B corresponding to A" means that B is associated with A, and B can be determined according to A. However, it should also be understood that determining B according to A does not mean determining B only according to A, and B can also be determined according to A and / or other information.

[0107] like Figure 1 As shown, a link recovery processing method according to an embodiment of the present invention is executed by a wireless communication device, including:

[0108] Step 101: receiving a link recovery signal sent by a first visible light device, wherein the link recovery signal includes information about idle public light beam resources of the first visible light device.

[0109] Here, the first visible light device is a visible light transmitter, and the link recovery signal is sent by the first visible light device in the event of a link loss event, and is used to trigger the wireless communication device to process the link recovery. The link recovery signal includes the idle public beam resource information of the first visible light device, which can facilitate the wireless communication device to coordinate the beam channel measurement based on the idle public beam resource information. Therefore, in this step, the wireless communication device receives the link recovery signal sent by the first visible light device to execute the next step.

[0110] Step 102: sending a first beam channel measurement signaling to the first visible light device and sending a second beam channel measurement signaling to the second visible light device according to the common beam resource information;

[0111] The first beam channel measurement signaling is used to instruct the first visible light device to send a beam measurement reference signal; and the second beam channel measurement signaling is used to instruct the second visible light device to perform measurement according to the beam measurement reference signal.

[0112] In this way, after the wireless communication device receives the link recovery signal sent by the first visible light device in step 101, it can, through step 102, send corresponding light beam channel measurement signaling to the first visible light device and the second visible light device respectively according to the common light beam resource information in the link recovery signal, guide the measurement between the first visible light device and the second visible light device, so as to restore the communication between the first visible light device and the second visible light device, thereby avoiding the high complexity and high power consumption caused by real-time blind detection in the measurement process of the first visible light device and the second visible light device.

[0113] The public beam resource information is specifically frequency band information.

[0114] It should be noted that the second visible light device is a receiving device of the first visible light device. The first visible light device can determine the occurrence of the link loss event according to the number of times that the confirmation ACK fed back by the second visible light device is not received reaches a preset number. The preset number is pre-set, such as set by the macNumAcks field.

[0115] Optionally, the link recovery signal further includes an identity ID of the first visible light device and an ID of the second visible light device.

[0116] In this way, when the wireless communication device sends the first beam channel measurement signaling and the second beam channel measurement signaling, it can clarify the target object of the transmission based on the first visible light device ID and the second visible light device ID in the link recovery signal, thereby improving the transmission efficiency.

[0117] In this embodiment, optionally, the first beam channel measurement signaling and the second beam channel measurement signaling include: beam indication information and time-frequency domain resources.

[0118] Here, the light beam indication information can also be understood as a light beam identification, indicating the light beam to be used subsequently. Specifically, the light beam indication information includes: light beam color, wavelength or frequency band, etc.

[0119] In this way, the wireless communication device can inform the light beam and time-frequency domain resources to be used through the first light beam channel measurement signaling and the second light beam channel measurement signaling, thereby ensuring the pertinence of the measurement and avoiding the first visible light device and the second visible light device from performing blind detection in real time. The light beam and time-frequency domain resources include the light beam and time-frequency domain resources used for light beam measurement reference signal transmission, and may also include the light beam and time-frequency domain resources used for measurement result feedback.

[0120] The beam indication information can be directly determined by the idle public beam resource information of the first visible light device. If the public beam resource information is a frequency band range (A, B), beam 1 and beam 2 belong to the frequency band range, that is, the beams used for measurement can be beam 1 and beam 2, then the beam indication information can be the color, wavelength or frequency band of beam 1 and beam 2. The time-frequency domain resources can be determined by the time-frequency domain resources recorded in the coordination history information of the wireless communication device itself, or can be determined based on the capability information or communication history information of the first visible light device and the second visible light device.

[0121] Of course, the light beam used for measurement can also be determined by the light beam indication information recorded in the coordination history information of the wireless communication device itself, or determined based on the capability information or communication history information of the first visible light device and the second visible light device, which will not be repeated here.

[0122] After receiving the first beam channel measurement signaling, the first visible light device sends a beam measurement reference signal, such as a Fast Link Recovery (FLR) signal. Specifically, based on the beam indication information and time-frequency domain resources in the first beam channel measurement signaling, the corresponding beam is used to send the beam measurement reference signal on the corresponding time-frequency domain resources.

[0123] When the second visible light device receives the second beam channel measurement signaling, it performs measurement according to the beam measurement reference signal. Specifically, based on the beam indication information and time-frequency domain resources in the second beam channel measurement signaling, for the corresponding beam, the corresponding time-frequency domain resources attempt to receive the beam measurement reference signal and perform measurement. The second visible light device needs to inform the first visible light device of the measurement result. The second visible light device can directly feedback the measurement result to the first visible light device, or forward it through the wireless communication network via the wireless communication device.

[0124] Optionally, after step 102, the method further includes:

[0125] receiving a measurement result sent by the second visible light device;

[0126] The measurement result is sent to the first visible light device.

[0127] In this embodiment, the second visible light device performs measurement, including but not limited to channel quality measurement, to obtain channel quality information. Of course, one or more light beams can also be selected through measurement to restore communication. Therefore, optionally, the measurement result includes channel quality information and / or target light beam.

[0128] The channel quality information includes: Channel Quality Indicator (CQI), Service Class Identifier (QCI), Reference Signal Received Quality (RSRQ), etc.

[0129] It should be noted that the first visible light device will start a timer to wait after sending the beam measurement reference signal. If no feedback on the measurement result is received within the set time, the link recovery signal will be sent to the wireless communication device again. Furthermore, if no measurement result is received within the specified number of attempts, the link connection is considered to have failed, and the visible light link access is performed again, or the data transmission is switched to wireless technology.

[0130] In addition, in this embodiment, in order to realize the interaction between the first visible light device or the second visible light device and the wireless communication device, optionally, when the first visible light device or the second visible light device is a network device, it is directly connected to the wireless communication device.

[0131] The direct connection may be achieved through an X2 interface or other interactive methods.

[0132] In addition, optionally, when the first visible light device or the second visible light device is a terminal device, it communicates with the wireless communication device through preset resources carried in the wireless communication network.

[0133] Among them, the preset resources may only limit the resource type, and the preset resources are competitive resources; or, the preset resources are resources that limit specific time domains and frequency domains. Moreover, the preset resources may not require scheduling (grant free); the preset resources may be resources of signaling such as the Media Access Control Element (MAC CE) or the Radio Resource Control (RRC). The preset resources correspond to uplink transmission, and can also be Physical Uplink Control Channel (PUCCH) resources; corresponding to downlink transmission, they can also be Physical Downlink Control Channel (PUCCH) resources.

[0134] Next, combine Figure 2 The application of the method of the embodiment of the present invention is described as follows:

[0135] Assuming that the visible light transmitting end (i.e., the first visible light device) detects that a link loss event occurs with the visible light receiving end (i.e., the second visible light device), it connects with the wireless base station respectively and executes:

[0136] S201, a visible light transmitter sends an FLR signal to a wireless base station (ie, a wireless communication device).

[0137] S202, the wireless base station sends a beam channel measurement signaling to the visible light transmitting end and the visible light receiving end respectively.

[0138] S203, the visible light transmitter sends a beam measurement reference signal on the time-frequency domain resources set by the wireless base station.

[0139] S204, the visible light receiving end performs measurement on the time-frequency domain resources set by the wireless base station, and sends the measurement result to the wireless base station.

[0140] S205, the wireless base station sends the measurement result to the visible light transmitting end.

[0141] S206, the visible light transmitting end and the visible light receiving end select a new light beam according to the measurement result to resume data transmission.

[0142] Among them, the visible light transmitter will start the timer to wait after sending the beam measurement reference signal. If no feedback on the measurement result is received within the set time, the FLR signal will be sent to the wireless base station again (return to S201); if no measurement result is received within the specified number of attempts, the link connection is considered to have failed, and the visible light link access will be re-performed, or data transmission will be switched to wireless technology.

[0143] To summarize, the method of an embodiment of the present invention is executed by a wireless communication device. After receiving a link recovery signal sent by the first visible light device, the method can send corresponding light beam channel measurement signaling to the first visible light device and the second visible light device respectively according to the common light beam resource information in the link recovery signal, guide the measurement between the first visible light device and the second visible light device, so as to restore the communication between the first visible light device and the second visible light device, thereby avoiding the high complexity and high power consumption of the measurement process of the first visible light device and the second visible light device due to real-time blind detection.

[0144] like Figure 3 As shown, the link recovery processing method of the embodiment of the present invention is performed by the first visible light device, including:

[0145] Step 301, sending a link recovery signal to a wireless communication device, wherein the link recovery signal includes information about idle public beam resources of the first visible light device;

[0146] Step 302: Receive a first beam channel measurement signaling sent by the wireless communication device, where the first beam channel measurement signaling is used to instruct the first visible light device to send a beam measurement reference signal.

[0147] In this way, after the link recovery signal is sent, the wireless communication device can send corresponding light beam channel measurement signaling to the first visible light device and the second visible light device respectively according to the common light beam resource information in the link recovery signal, guide the measurement between the first visible light device and the second visible light device, so as to restore the communication between the first visible light device and the second visible light device, and avoid the high complexity and high power consumption caused by real-time blind detection in the measurement process of the first visible light device and the second visible light device.

[0159] Here, the second beam channel measurement signaling is sent by the wireless communication device according to the common beam resource information in the link recovery signal after the wireless communication device receives the link recovery signal sent by the first visible light device. In addition, the wireless communication device will also send the corresponding beam channel measurement signaling to the first visible light device to guide the measurement between the first visible light device and the second visible light device, so as to restore the communication between the first visible light device and the second visible light device, thereby avoiding the high complexity and high power consumption caused by the real-time blind detection in the measurement process between the first visible light device and the second visible light device.
