Description

Technical Field

[0001] This invention relates to the field of heterogeneous network communication technology, specifically to a measurement method, a terminal, and an access network device. Background Technology

[0002] Indoor visible light communication (VLC) utilizes the high-speed flashing of light-emitting diodes (LEDs) to transmit information, using free space as the transmission channel. It is a high-speed and environmentally friendly new indoor access network technology. In visible light communication, to reduce power consumption and extend battery life, terminals typically have five modes: L0-L4, as detailed below:

[0003] Normal mode (L0): Maximum data transfer rate.

[0004] Power reduction mode (L1): such as Figure 1 As shown, the inactivity period is part of a MAC cycle, which is similar to a wireless frame in wireless communication.

[0005] Low-power mode (L2): This mode is applied when data transmission is reduced, such as... Figure 2 As shown, the hibernation period spans multiple MAC cycles, up to a maximum of 36,000 MAC cycles.

[0006] Standby mode (L3): This mode is used when there is no data transmission. The sleep period is indefinite and the device is woken up when there is data again.

[0007] Idle mode (L4): No data or control information is transmitted or received.

[0008] In practical visible light communication systems, both signal light and background light are involved. Background light, as an interference source, causes shot noise. When the background light is relatively weak, the noise in the optical channel mainly comes from the thermal noise of the preamplifier. In visible light communication, thermal noise is much weaker than shot noise. Therefore, most of the noise in visible light communication comes from interference from background light sources, which include natural and artificial light sources. These light sources are usually used for lighting and daily life and are difficult to cut off at the source.

[0009] Signal light can be interrupted due to obstructions, and background light intensity can also fluctuate, causing the Received Light Strength (RLS) to change continuously. In direct detection and receiving systems using threshold detectors (APD and CCD), the detector can receive the signal light when the received light intensity is greater than the threshold, but cannot receive the signal light when the received light intensity is less than the threshold.

[0010] Because LED light sources have a certain directionality, their coverage area is relatively small. When users move to areas not covered by visible light communication, service will be interrupted. Furthermore, compared to the penetration of wireless communication, VLC is easily affected by obstructions, causing communication link interruptions. In practical applications, implementing uplink in visible light is difficult, so VLC is generally combined with other wireless access methods for heterogeneous networking. In heterogeneous visible light communication networks, it is assumed that visible light only has downlink and no uplink, while both uplink and downlink of the radio frequency link exist.

[0011] Within a room, when the quality of the visible light downlink signal deteriorates to a certain level, the terminal will switch to the visible light base station with better signal quality if other visible light base stations are present in the network; otherwise, it will switch to radio frequency downlink. To ensure system capacity, the terminal monitors the quality of the visible light downlink while receiving data from the downlink radio frequency link, following the principle of visible light priority. Once the visible light downlink signal quality is detected to be good, the terminal will switch back to visible light downlink. When the terminal enters another room, it will switch to the new visible light base station once the downlink signal quality of another visible light base station is detected to be good.

[0012] During this monitoring process, the terminal activates its radio frequency receiving circuit. If the terminal's visible light receiving circuit also remains active, it will significantly increase power consumption and reduce battery life. Considering that the terminal enters power-saving mode during monitoring, a power-saving method for the terminal in a heterogeneous visible light network needs to be designed.

[0107] Please see Figure 3 , Figure 3 This diagram illustrates a block diagram of a radio frequency access communication system applicable to heterogeneous networks according to embodiments of the present invention. The radio frequency access communication system includes a terminal 11 and an access network device 12. The terminal 11 can also be referred to as a user terminal or user equipment (UE). The terminal 11 can be a mobile phone, tablet computer, laptop computer, personal digital assistant (PDA), mobile internet device (MID), wearable device, or vehicle-mounted device, etc. It should be noted that the specific type of terminal 11 is not limited in this embodiment of the present invention. Access network device 12 can be a base station and / or various access points. The base station can be a 5G or later version base station (e.g., gNB, 5G NR NB, etc.), or a base station in other communication systems (e.g., eNB, WLAN access point, or other access point, etc.). The base station can be referred to as Node B, Evolved Node B, Access Point, Base Transceiver Station (BTS), Radio Base Station, Radio Transceiver, Basic Service Set (BSS), Extended Service Set (ESS), B Node, Evolved B Node (eNB), Home B Node, Home Evolved B Node, WLAN Access Point, WiFi Node, or any other suitable term in the field, as long as the same technical effect is achieved. The base station is not limited to specific technical terms. It should be noted that in the embodiments of the present invention, only the base station in the NR system is used as an example, but the specific type of base station is not limited.

[0108] The base station can communicate with terminal 11 under the control of a base station controller, which in various examples may be part of the core network or some base stations. Some base stations may communicate control information or user data with the core network via backhaul. In some examples, some of these base stations may communicate with each other directly or indirectly via backhaul links, which may be wired or wireless communication links. The wireless communication system may support operation on multiple carriers (waveform signals of different frequencies). A multi-carrier transmitter can transmit modulated signals on multiple carriers simultaneously. For example, each communication link may be a multi-carrier signal modulated according to various radio technologies. Each modulated signal may be transmitted on a different carrier and may carry control information (e.g., reference signals, control channels, etc.), overhead information, data, etc.

[0109] The base station can wirelessly communicate with terminal 11 via one or more access point antennas. Each base station can provide communication coverage for its respective coverage area. The coverage area of ​​an access point can be divided into sectors that constitute only a part of that coverage area. The wireless communication system may include different types of base stations (e.g., macro base stations, micro base stations, or pico base stations). Base stations may also utilize different radio technologies, such as cellular or WLAN radio access technologies. Base stations may be associated with the same or different access networks or operator deployments. The coverage areas of different base stations (including coverage areas of the same or different types of base stations, coverage areas using the same or different radio technologies, or coverage areas belonging to the same or different access networks) may overlap.

[0110] Communication links in a radio frequency access communication system may include an uplink radio frequency link for carrying uplink (UL) transmissions (e.g., from terminal 11 to network device 12) or a downlink radio frequency link for carrying downlink (DL) transmissions (e.g., from network device 12 to terminal 11). UL transmissions may also be referred to as reverse link transmissions, and DL transmissions may also be referred to as forward link transmissions. Downlink transmissions may be carried out using licensed frequency bands, unlicensed frequency bands, or both. Similarly, uplink transmissions may be carried out using licensed frequency bands, unlicensed frequency bands, or both.

[0111] In this application, the radio frequency link can be the uplink or downlink of a cellular network (4G / 5G, etc.). Through the terminal power-saving method design using visible light heterogeneous networking, when the terminal selects radio frequency downlink communication and simultaneously monitors the quality of the visible light downlink signal, the visible light receiving circuit can be shut down during the sleep period, monitoring only during the active period, thereby reducing terminal power consumption. Furthermore, since the terminal only measures during the active period, the relevant configurations for the power-saving mode can reuse measurement timing configurations (MTC), including the measurement window period, the duration of measurement for each frequency carrier, timing offset, etc., thereby reducing signaling overhead.

[0112] Please refer to Figure 4 The measurement method provided in this embodiment of the invention, when applied to the terminal side, includes:

[0113] Step 41: Send the measurement result of the second downlink channel quality to the first access network device, where the second downlink is the link between the terminal and the second access network device.

[0114] Here, the first access network device and the second access network device provide different access methods for the terminal, meaning they are devices based on different access technologies. For example, the first access network device can provide radio frequency access to the terminal, specifically a cellular network (4G / 5G, etc.) access device, such as various radio frequency base stations or access points; the second access network device can provide visible light access to the terminal, such as a visible light base station in a visible light communication system. In step 41 above, the terminal can operate in power-saving mode or normal mode. The terminal measures the channel quality of the second downlink from the second access network device to itself, obtains the measurement result, and reports the result to the first access network device. The downlink from the first access network device to the terminal is called the first downlink, and the downlink from the second access network device to the terminal is called the second downlink.

[0115] The first access network device receives the measurement results and, based on the results and preset decision conditions, determines the terminal's operating mode (e.g., whether the receiving circuit of the second downlink needs to enter energy-saving mode). It then determines and controls whether the first access network device transmits service data to the terminal via the first downlink, or whether the second access network device transmits service data to the terminal via the second downlink. Furthermore, it determines the terminal's monitoring method for the second downlink, and subsequently selects a suitable measurement configuration for the terminal. The first access network device can then send the selected measurement configuration to the terminal.

[0116] Step 42: Obtain the measurement configuration selected by the first access network device for the terminal.

[0117] Here, the terminal receives the measurement configuration selected by the first access network device for the terminal, and performs corresponding processing according to the measurement configuration. Specifically, it may include at least one of the following: setting the terminal's working mode (e.g., whether the receiving circuit of the second downlink needs to enter the power saving mode), receiving service data sent by the first access network device through the first downlink, or receiving service data sent by the second access network device through the second downlink, and determining the terminal's monitoring method for the second downlink, and monitoring the link quality of the second downlink according to the determined monitoring method, etc.

[0118] Through the above steps, this embodiment of the invention enables measurement and configuration of terminals in a visible light heterogeneous network, providing support for terminal energy saving. For example, when the quality of the second downlink is poor, the terminal can be controlled to access an energy-saving mode to reduce the power consumption of the receiving circuit that receives data from the second downlink.

[0119] The steps described above will be explained in more detail below.

[0120] The terminal typically includes a first receiving circuit for receiving signals from a first downlink, and a second receiving circuit for receiving signals from a second downlink.

[0121] In step 41 above, the measurement result can be a first measurement result obtained by the terminal operating in normal mode, in which the terminal receives downlink data through the second downlink. In step 42 above, the terminal can receive a first measurement configuration sent by the first access network device, the first measurement configuration including at least one of the following:

[0122] 1) First indication information used to instruct the terminal to enter power-saving mode;

[0123] 2) Energy-saving mode configuration information;

[0124] 3) Second indication information used to instruct the terminal to receive the first downlink channel data.

[0125] Here, the energy-saving mode configuration information includes at least one measurement cycle, the measurement cycle including adjacent non-measurement windows and measurement windows; the non-measurement windows include a first number of consecutive time units, and the measurement windows include a second number of consecutive time units.

[0126] It should be noted that the above-mentioned energy-saving mode configuration information can also be pre-configured on the terminal side, or configured to the terminal by the first access network device or the second access network device when the terminal accesses the network. In this case, the above-mentioned energy-saving mode configuration information may not be included in the first measurement configuration.

[0127] The terminal entering energy-saving mode refers to the terminal periodically turning the second receiving circuit off and on according to the measurement cycle configured in the energy-saving mode configuration information, in order to reduce receiving power consumption. In this embodiment of the invention, the terminal's operating modes include normal mode and energy-saving mode. In normal mode, the terminal receives data sent by the second access network device through the second receiving circuit; in energy-saving mode, the terminal periodically turns the second receiving circuit off and on, and receives data sent by the first access network device through the first receiving circuit.

[0128] Thus, after step 42 above, the terminal can enter energy-saving mode according to the first indication information and energy-saving mode configuration information, turn off the second receiving circuit, and / or, according to the second indication information, switch the receiving circuit for service data, that is, receive service data sent by the first access network device through the first receiving circuit. For example, if the terminal is already in energy-saving mode when the first measurement configuration is received, the terminal will remain in energy-saving mode according to the first indication information. In addition, when the energy-saving mode configuration information adjusts the measurement period and other configurations, the terminal can also adjust the relevant parameters in energy-saving mode according to the energy-saving mode configuration information, such as the duration of the measurement period and the proportion of non-measurement windows within the measurement period.

[0129] In one implementation, in energy-saving mode, the terminal enters a sleep state during the non-measurement window of the measurement cycle, shuts down the second receiving circuit, and does not measure the quality of the second downlink channel; and when the measurement window enters an active state, it turns on the second receiving circuit, measures the quality of the second downlink channel, and reports the measurement result to the first access network device.

[0130] In this document, the sleep state or active state generally refers to the operating state of the second receiving circuit in the terminal that receives the second downlink signal. In the sleep state, the terminal can turn off this part of the receiving circuit or reduce the operating time of this part of the receiving circuit to reduce power consumption. In the active state, the terminal can turn on this part of the receiving circuit to receive the data of the second downlink or monitor the signal quality of the second downlink.

[0131] As another implementation, in power-saving mode, the terminal enters a sleep state during the non-measurement window of the measurement cycle and does not measure the second downlink channel quality; and, within the non-measurement window, at a first offset position before the start position of the measurement window, the received signal strength is measured, where the received signal strength is the received optical intensity (RLS), and the received light includes signal light and background light.

[0132] If the measured received signal strength is greater than a preset first threshold, the terminal enters an active state in the measurement window, measures the second downlink channel quality at a second offset position after the starting position of the measurement window, and sends the measured second measurement result to the first access network device.

[0133] If the received signal strength is not greater than the first threshold, the terminal enters a sleep state during the measurement window and does not measure the second downlink channel quality, thereby further reducing the receiving power consumption within the terminal's active window.

[0134] Furthermore, the first access network device can also adjust the proportion of non-measurement windows in the measurement cycle under energy-saving mode, and / or adjust the duration of the measurement cycle to adjust the energy-saving effect of the receiving circuit. For example, when the first indication information is used to indicate entering the first energy-saving mode, and the measurement cycle of the first energy-saving mode is the first measurement cycle, the terminal can also receive first information sent by the first access network device, the first information being used to indicate that the terminal enters the second energy-saving mode, the measurement cycle of the second energy-saving mode being the second measurement cycle, wherein the duration of the second measurement cycle is greater than the duration of the first measurement cycle, and / or, the proportion of non-measurement windows in the second measurement cycle is greater than the proportion of non-measurement windows in the first measurement cycle. By controlling the terminal to enter the energy-saving mode based on the second measurement cycle, the energy-saving effect can be further improved, and the terminal's energy consumption can be further reduced.

[0135] In step 41 above, the measurement result may be a second measurement result obtained by the terminal operating in energy-saving mode. In energy-saving mode, the terminal receives downlink data through the first downlink between itself and the first access network device. Additionally, in energy-saving mode, the terminal shuts down the receiving circuit for receiving the second downlink for at least a portion of the time, where the portion of the time refers to a portion of the time during operation in energy-saving mode. In step 42 above, the terminal may receive a second measurement configuration sent by the first access network device, the second measurement configuration including at least one of the following:

[0136] Third indication information used to instruct the terminal to exit power-saving mode;

[0137] Fourth indication information used to instruct the terminal to receive second downlink channel data.

[0138] Thus, after step 42 above, the terminal can exit the energy-saving mode according to the third instruction information, that is, turn on the second receiving circuit, and switch the receiving circuit for service data according to the fourth instruction information above, that is, receive service data sent by the second access network device through the second receiving circuit.

[0139] In step 42 above, the terminal may also receive a third measurement configuration sent by the first access network device, the third measurement configuration being used to instruct the terminal to disconnect from the second access network device. Thus, after step 42, the terminal disconnects from the second access network device according to the third measurement configuration. Furthermore, after disconnecting from the second access network device, the terminal may also shut down the second receiving circuit to conserve power.

[0140] Please refer to Figure 5 The measurement method provided in this embodiment of the invention, when applied to the first access network device (such as a radio frequency base station), includes:

[0141] Step 51: Receive the measurement result of the second downlink channel quality sent by the terminal, where the second downlink is the link between the terminal and the second access network device.

[0142] Here, the first and second access network devices can provide access to the terminal based on different access methods. For example, the first access network device can be a cellular network radio frequency base station, and the second access network device can be a visible light base station. The first access network device can receive the measurement results reported by the terminal through the radio frequency uplink.

[0143] Step 52: Based on the measurement results and decision conditions, select a measurement configuration for the terminal and send the selected measurement configuration to the terminal.

[0144] Here, the decision conditions can be pre-configured, specifically, they can be the correspondence between different second downlink channel quality and measurement configurations.

[0145] Through the above steps, this embodiment of the invention can receive the downlink signal quality of the second access network device reported by the terminal through the first access network device, and select and send the measurement configuration of the terminal accordingly, and configure the working state of the second receiving circuit of the terminal, so as to save the power consumption of the terminal.

[0146] In step 51 above, the measurement result may be a first measurement result obtained by the terminal working in normal mode, in which the terminal receives downlink data through the second downlink; in step 52 above, the first access network device compares the first measurement result with a preset first quality threshold, and selects a measurement configuration for the terminal based on the comparison result.

[0147] Specifically, if the first measurement result is worse than a first quality threshold, a first measurement configuration is sent to the terminal, the first measurement configuration including at least one of the following:

[0148] First indication information used to instruct the terminal to enter power-saving mode;

[0149] Energy-saving mode configuration information;

[0150] Second indication information used to instruct the terminal to receive first downlink channel data.

[0151] Here, the terminal entering power-saving mode means that the terminal periodically turns the second receiving circuit off and on according to the measurement cycle configured in the power-saving mode configuration information to reduce receiving power consumption. If the terminal is already in power-saving mode, the first indication information is used to instruct the terminal to continue in power-saving mode. In addition, the relevant parameters of the terminal in power-saving mode can also be adjusted through the power-saving mode configuration information.

[0152] If the first measurement result is worse than the first quality threshold, and if the second access network device is currently sending data to the terminal, or if the terminal is currently operating in normal mode, the first access network device can also send a first notification message to the second access network device to instruct it to stop sending data to the terminal, and send data to the terminal via the first downlink, wherein the first downlink is the link between the terminal and the first access network device. Through the above processing steps, this embodiment of the invention adjusts the terminal's operating mode (enters energy-saving mode) when the downlink quality of the second access network device is poor, and sends data to the terminal via the downlink of the first access network device, thereby improving data transmission reliability and saving the terminal's receiving power consumption.

[0153] After the terminal enters power-saving mode, it can also activate the second receiving circuit and measure the signal quality of the second downlink within the measurement window of the measurement cycle, obtain a second measurement result, and report the measurement result to the first access network device. At this time, the first access network device can also receive the second measurement result of the second downlink channel quality obtained by the terminal in power-saving mode, and perform the following processing based on the second measurement result:

[0154] In step 51 above, the measurement result may be a second measurement result obtained by the terminal operating in power-saving mode, in which the terminal receives downlink data through the first downlink between itself and the first access network device; additionally, in power-saving mode, the terminal shuts down the receiving circuit for receiving the second downlink at least for a portion of the time. At this time, in step 52 above, if the second measurement result is better than a second quality threshold, the first access network device stops sending data to the terminal through the first downlink, sends a second measurement configuration to the terminal, and sends a second notification message to the second access network device to indicate the resumption of sending data to the terminal, the second measurement configuration including at least one of the following:

[0155] Third indication information used to instruct the terminal to exit power-saving mode;

[0156] Fourth indication information used to instruct the terminal to receive second downlink channel data.

[0157] Through the above processing, the embodiments of the present invention can restore the data transmission from the second access network device to the terminal when the quality of the second downlink improves, and control the terminal to exit the power-saving mode so as to receive the data transmitted and transmitted by the second downlink through the second receiving circuit.

[0158] The second quality threshold is more stringent than the first quality threshold. It is assumed that the signal quality reflected by the second measurement result that is better than the second quality threshold is the second signal quality, and the signal quality reflected by the first measurement result that is better than the first quality threshold is the first signal quality. Usually, the second signal quality is better than or equal to the first signal quality.

[0159] This invention can also dynamically adjust the configuration of the energy-saving mode to further reduce the number of measurements or the measurement time of the terminal in energy-saving mode, thereby saving the power consumption of the terminal in measuring the second downlink in energy-saving mode. Furthermore, if the quality of the second downlink is consistently poor, this invention can also disconnect the second downlink connection.

[0160] Here, it is assumed that the first indication information is used to indicate entering the first energy-saving mode, and the measurement cycle of the first energy-saving mode is the first measurement cycle. As one implementation, the first access network device may also start a first timer after sending the first measurement configuration to the terminal.

[0161] If, after the first timer expires, or within N consecutive measurement cycles prior to the first timer's expiration, no second measurement result better than the second quality threshold is received, or if, before the first timer expires, a second measurement result worse than the third quality threshold is received, then a first message is sent to the terminal. This first message instructs the terminal to enter a second power-saving mode. The measurement cycle of the second power-saving mode is the second measurement cycle, wherein the duration of the second measurement cycle is greater than the duration of the first measurement cycle, and / or the proportion of non-measurement windows in the second measurement cycle is greater than the proportion of non-measurement windows in the first measurement cycle. Here, N is a preset positive integer. The second measurement result is the measurement result obtained by the terminal operating in power-saving mode.

[0162] Assuming that the signal quality reflected by the second measurement result which is inferior to the third quality threshold is the third signal quality, and the signal quality reflected by the first measurement result which is inferior to the first quality threshold is the fourth signal quality, the third signal quality is generally not better than the fourth signal quality.

[0163] Through the above steps, this embodiment of the invention further reduces the number of measurements and / or the measurement duration within the measurement cycle when the signal quality of the second downlink is in a poor state for an extended period, thereby reducing the measurement power consumption of the terminal in power-saving mode.

[0164] In addition, after sending the first measurement configuration, the first access network device may also start a second timer, wherein the timeout period of the second timer is longer than the timeout period of the first timer.

[0165] If no second measurement result better than the second quality threshold is received after the second timer expires, or if a second measurement result worse than the fourth quality threshold is received before the second timer expires, then a third measurement configuration is sent to the terminal and a third notification message is sent to the second access network device. The third measurement configuration is used to instruct the terminal to disconnect from the second access network device, and the third notification message is used to instruct the second access network device to disconnect from the terminal.

[0166] If the signal quality reflected by the second measurement result that is inferior to the third quality threshold is the third signal quality, and the signal quality reflected by the second measurement result that is inferior to the fourth quality threshold is the fifth signal quality, then the fifth signal quality is not better than the third signal quality.

[0167] Through the above steps, in the case where the signal quality of the second downlink is in a poor state for a longer period of time, or the signal quality becomes worse, the connection between the terminal and the second access network device is disconnected, thereby shutting down the second receiving circuit for a long time and no longer measuring the signal quality of the second downlink, further reducing the measurement power consumption of the terminal in power-saving mode.

[0168] Please refer to Figure 6 The measurement method provided in this embodiment of the invention, when applied to a second access network device (such as a visible light base station), includes:

[0169] Step 61: Send service data to the terminal through the second downlink, whereby the second downlink is the link between the terminal and the second access network device.

[0170] Step 62: Receive a first notification message from the first access network device indicating to stop sending data to the terminal. The first notification message is sent by the first access network device when the first measurement result is worse than a first quality threshold. The first measurement result is the measurement result of the second downlink channel quality obtained by the terminal in normal mode. In the normal mode, the terminal receives downlink data through the second downlink.

[0171] Step 63: According to the first notification message, stop sending the data to the terminal through the second downlink.

[0172] Through the above steps, this embodiment of the invention enables the first access network device to adjust the terminal data transmission link based on the measurement results of the signal quality of the two downlinks, thereby allowing the terminal to enter an energy-saving mode to reduce the terminal's receiving power consumption.

[0173] Similarly, the second access network device can also receive a second notification message sent by the first access network device to indicate the resumption of data transmission to the terminal. The second notification message is sent by the first access network device when a second measurement result is better than a second quality threshold. The second measurement result is a measurement result of the second downlink channel quality obtained by the terminal in power-saving mode. Then, according to the second notification message, the data transmission to the terminal is resumed through the second downlink.

[0174] The second access network device can also receive a third notification message sent by the first access network device, which instructs the second access network device to disconnect from the terminal; and then disconnect from the terminal according to the third notification message.

[0175] The method of the present invention will be described in detail below using radio frequency base stations (first access network equipment) and visible light base stations (second access network equipment) as examples, with more specific examples. In the following examples, the second downlink is a visible light downlink, and the first downlink is a radio frequency downlink.

[0176] Please refer to Figure 7 It provides an example of the triggering conditions and effective time for a terminal to enter power-saving mode:

[0177] S1. The terminal receives the visible light downlink signal and measures the received visible light downlink signal.

[0178] Here, the visible light downlink signal can be a visible light reference signal.

[0179] S2. The terminal feeds back the measured downlink visible light signal strength to the radio frequency base station via the uplink radio frequency link.

[0180] Here, the visible light downlink signal strength can be RSRP / RSRQ, etc.

[0181] S3. The radio frequency base station compares the received signal strength with a threshold value. Here, it is assumed that the signal strength is greater than or equal to the first threshold value. The radio frequency base station notifies the visible light base station that the downlink signal transmission configuration remains unchanged, or no processing is performed, and then proceeds to steps S4-S5. Steps S4-S5 are similar to steps S1-S2 above.

[0182] In S61-S62, the radio frequency base station compares the received signal strength with a threshold value. Here, it is assumed that the signal strength is less than the first threshold value. At this time, the radio frequency base station starts downlink data transmission, notifies the visible light base station to stop data transmission, and notifies the terminal to enter power-saving mode and receive data through the radio frequency base station. The next time unit (time slot / transmission opportunity, etc.) takes effect (S7).

[0183] Specifically, the radio frequency base station can send a 1-bit signaling instruction to the visible light base station to notify whether to update the visible light downlink signal transmission. If it is 1, it means that no update is needed and the visible light continues to transmit downlink data; if it is 0, it means that the visible light base station needs to enter the power saving mode, stop the downlink data transmission, and update the downlink signal transmission configuration in the next time unit.

[0184] Please refer to Figure 8 An example of the measurement behavior of the terminal's power-saving mode is provided, including:

[0185] The terminal receives a power-saving mode activation signal from the downlink radio frequency link, which takes effect in the next time unit, and the terminal enters the first power-saving monitoring cycle.

[0186] a) The first energy-saving monitoring cycle refers to the first measurement cycle of the visible light downlink measurement reference symbol;

[0187] b) The first measurement cycle includes a measurement window and a non-measurement window. During the measurement window, the terminal starts monitoring the downlink signal strength of visible light from the first offset position. During the non-measurement window, the terminal turns off the downlink receiving circuit of visible light and enters a sleep state, and does not monitor the downlink signal strength of visible light to reduce power consumption.

[0188] c) Starting from the beginning of the first measurement cycle, a first number of consecutive time units are in the non-measurement window (sleep period); after the terminal wakes up from the sleep state, a second number of consecutive time units are in the measurement window (activation period), and the terminal starts monitoring the downlink signal strength of visible light from the first offset position; the duration and offset configuration can be carried in the power-saving mode activation signaling or can be the default configuration.

[0189] d) To further reduce power consumption, the terminal wakes up at the second offset position before the measurement window to measure the received light intensity (RLS), including signal light and background light (Level 1 measurement); if the received light intensity is greater than the second threshold, it means that the terminal detector can receive the signal light, and the terminal wakes up in the measurement window to measure the signal intensity (Level 2 measurement); if the received light intensity is less than the second threshold, it means that the terminal detector cannot receive the signal light, and the terminal also goes into sleep mode in the measurement window, turning off the visible light downlink receiving circuit.

[0190] e) When measuring signal strength during the activation period, measurements can be performed on all sub-channels in the frequency domain; considering that the frequency response characteristics of visible light are different on different channels, measurements can also be performed on some sub-channels / BWP with good frequency response characteristics; the sub-channels may be continuous or discontinuous.

[0191] Please refer to Figure 9 This provides another example of the measurement behavior of terminal power-saving modes, including:

[0192] When the energy-saving mode is activated, the first and second timers are started. When certain conditions are met, the level 2 cycle setting is executed.

[0193] a) If the terminal fails to perform Level 2 measurement for a first number of first measurement cycles or after the first timer expires, or if the measured visible light downlink signal strength is too poor, the radio frequency base station will send a measurement cycle switching indication signaling.

[0194] b) The signaling takes effect in the next time unit.

[0195] c) The signaling includes a second measurement cycle configuration, a measurement window duration and a first offset configuration, a level 2 measurement configuration and a frequency domain monitoring configuration.

[0196] i. The duration of the second measurement cycle can be configured directly or a scaling factor α can be indicated. The second measurement cycle is longer than the first measurement cycle. Since the terminal has not woken up for the first number of cycles or the timer has expired, it indicates that the visible light signal strength is weak and cannot be recovered temporarily. The terminal may be moving into another room. Considering the movement of the terminal, the power consumption can be further reduced by lengthening the sleep cycle.

[0197] ii. The measurement window and non-measurement window can be configured directly, or the measurement window duration and position can be left unchanged by default, and only the duration of the second measurement cycle can be configured.

[0198] iii. The Level 2 measurement configuration remains unchanged.

[0199] iv. The frequency domain monitoring configuration remains unchanged.

[0200] Please refer to Figure 10 An example of the conditions for turning off the terminal's power-saving mode is provided, including:

[0201] 1. Within the second timer, in any measurement window of a measurement cycle, as long as the signal strength of any visible light base station is measured to be greater than or equal to the first threshold value, the radio frequency base station will notify the target visible light base station to start downlink data transmission and notify the terminal to end the power-saving mode, which will take effect in the next time unit; if the signal strength is less than the first threshold value, no action will be taken and the terminal will continue to be in power-saving mode.

[0202] 2. After the second timer expires, disconnect from visible light.

[0203] As can be seen from the above examples, the embodiments of the present invention can turn off the visible light receiving circuit during the sleep period and monitor only during the active period when the terminal selects radio frequency downlink communication and monitors the quality of visible light downlink signal. This reduces the power consumption of the terminal. In addition, since the terminal only measures during the active period, the relevant configuration of the power saving mode can reuse the measurement timing configuration (MTC) configuration, including the measurement window period, the duration of measurement for each frequency carrier, timing offset, etc., thereby reducing signaling overhead.

[0204] The various methods of the embodiments of the present invention have been described above. Apparatus for implementing the above methods will now be provided.

[0205] Please refer to Figure 11 This invention provides a terminal, comprising:
