Description

Measurement method, terminal and access network equipment

Technical Field

The invention relates to the technical field of heterogeneous networking communication, in particular to a measuring method, a terminal and access network equipment.

Background

Indoor Visible Light Communication (VLC) utilizes high-speed flicker transmission information of Light Emitting Diode (LED) lamps, takes free space as a transmission channel, and is a novel high-speed environment-friendly indoor access network technology. In visible light communication, in order to reduce power consumption and increase the service life of a battery, a terminal generally has five modes L0-L4, specifically as follows:

normal mode (L0): the maximum data transmission rate.

Power consumption reduction mode (L1): as shown in fig. 1, a sleep period (inactivity period) occupies a part of one MAC cycle (MAC cycle), which is similar to a radio frame in wireless communication.

Low power mode (L2): this mode is applied when data transmission is reduced, as shown in fig. 2, the sleep period accounts for a number of MAC cycles up to 36000MAC cycles.

Standby mode (L3): this mode is applied when there is no data transfer, the sleep period is not fixed, and it is woken up when there is data again.

Idle mode (L4): there is no transceiving of any data or control information.

In an actual visible light communication system, both signal light and background light are included. Background light as an interference source will cause shot noise, and when the background light is weak, the noise in the optical channel mainly comes from the thermal noise of the front amplifier. In visible light communications, thermal noise can be much weaker than shot noise. Therefore, the noise of visible light communication is mostly caused by the interference of background light sources, such as natural light sources and artificial light sources, which are generally used for illumination and life and are difficult to cut off from the source.

The signal Light may cause interruption of the communication link due to occlusion, and the background Light intensity may also change continuously, so that the Received Light intensity (RLS) also changes continuously. In a direct detection receiving system using threshold detectors (APD and CCD), when the received light intensity is greater than a threshold value, the detector can receive the signal light, and when the received light intensity is less than the threshold value, the detector cannot receive the signal light.

Because the light emitted by the LED light source has certain directivity, the coverage area of the LED light source is small, and when a user moves to an area which cannot be covered by visible light communication, the service can be interrupted; furthermore, VLCs are susceptible to obstructions that cause disruption of the communication link, as compared to the penetration of wireless communications. Meanwhile, in practical application, the difficulty in realizing uplink of visible light is high, VLC and other wireless access modes are generally combined to perform heterogeneous networking, and in the visible light communication heterogeneous networking, it is assumed that visible light only has downlink and no uplink, and both uplink and downlink of a radio frequency link exist.

In a room, when the quality of a visible light downlink signal is poor to a certain degree, if other visible light base stations exist in a network, the visible light base station with better signal quality is switched to; otherwise, switching to radio frequency downlink, in order to ensure system capacity, monitoring the quality of the visible light downlink when the terminal receives data of a downlink radio frequency link, and switching back to the visible light downlink once the signal quality of the visible light downlink is better; when the terminal enters another room, once the downlink signal quality of other visible light base stations is better, a new visible light base station is switched to.

In the monitoring process, the terminal starts the radio frequency receiving circuit, and if the visible light receiving circuit of the terminal is also started all the time, the power consumption of the terminal is greatly increased, and the service life of a battery is reduced. Considering that the terminal enters an energy-saving mode in the monitoring process, the terminal energy-saving method of the visible light heterogeneous networking needs to be designed.

Referring to fig. 3, fig. 3 is a block diagram of a radio frequency access communication system in a heterogeneous network to which an embodiment of the present invention is applicable. The radio frequency access communication system comprises a terminal 11 and an access network device 12. The terminal 11 may also be referred to as a User terminal or a User Equipment (UE), where the terminal 11 may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or a vehicle-mounted Device, and the specific type of the terminal 11 is not limited in the embodiment of the present invention. The access network device 12 may be a Base Station and/or various access points, wherein the Base Station may be a 5G or later-version Base Station (e.g., a gNB, a 5G NR NB, etc.), or a Base Station in other communication systems (e.g., an eNB, a WLAN access point, or other access points, etc.), wherein the Base Station may be referred to as a node B, an evolved node B, an access point, a Base Transceiver Station (BTS), a radio Base Station, a radio Transceiver, a Basic Service Set (BSS), an Extended Service Set (ESS), a node B, an evolved node B (eNB), a home node B, a home evolved node B, a WLAN access point, a WiFi node, or some other suitable terminology in the field, as long as the same technical effect is achieved, the Base Station is not limited to a specific technical vocabulary, and it should be noted that the Base Station in the NR system is only taken as an example in the embodiment of the present invention, but the specific type of the Base Station is not limited.

The base stations may communicate with the terminals 11 under the control of a base station controller, which may be part of the core network or some of the base stations in various examples. Some base stations may communicate control information or user data with the core network through a backhaul. In some examples, some of the base stations may communicate with each other, directly or indirectly, over backhaul links, which may be wired or wireless communication links. A wireless communication system may support operation on multiple carriers (waveform signals of different frequencies). A multi-carrier transmitter can transmit modulated signals on the 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, and so on.

The base station may communicate wirelessly with the terminal 11 via one or more access point antennas. Each base station may provide communication coverage for a respective coverage area. The coverage area of an access point may be divided into sectors that form only a portion of the coverage area. A wireless communication system may include base stations of different types (e.g., macro, micro, or pico base stations). The base stations may also utilize different radio technologies, such as cellular or WLAN radio access technologies. The 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 base stations of the same or different types, coverage areas utilizing the same or different radio technologies, or coverage areas belonging to the same or different access networks) may overlap.

The communication link in the radio frequency access communication system may comprise an Uplink radio frequency link for carrying Uplink (UL) transmissions (e.g. from the terminal 11 to the network device 12) or a Downlink radio frequency link for carrying Downlink (DL) transmissions (e.g. from the network device 12 to the terminal 11). The UL transmission may also be referred to as reverse link transmission, while the DL transmission may also be referred to as forward link transmission. Downlink transmissions may be made using licensed frequency bands, unlicensed frequency bands, or both. Similarly, uplink transmissions may be made using licensed frequency bands, unlicensed frequency bands, or both.

In the present application, the radio frequency link may be an uplink and a downlink of a cellular network (4G/5G, etc.). Through the design of the energy-saving method of the terminal of the visible light heterogeneous network, when the terminal selects radio frequency downlink communication and simultaneously monitors the quality of visible light downlink signals, the visible light receiving circuit is closed in the dormant period and is only monitored in the activation period, so that the power consumption of the terminal is reduced. In addition, the terminal only measures in the active period, and the related configuration of the energy saving mode may reuse a Measurement Timing Configuration (MTC) configuration, including a measurement window period, a duration of each frequency carrier measurement, a timing offset, and the like, thereby reducing signaling overhead.

Referring to fig. 4, a measurement method provided in an embodiment of the present invention, when applied to a terminal side, includes:

step 41, sending a measurement result of a second downlink channel quality to the first access network device, where the second downlink is a link between the terminal and the second access network device.

Here, the first access network device and the second access network device provide different access modes for the terminal, that is, the two access network devices are devices based on different access technologies. For example, the first access network device may be capable of providing radio frequency access to the terminal, and specifically may be an access device of a cellular network (4G/5G, etc.), such as various radio frequency base stations or access points; the second access network device is capable of providing visible light access to the terminal, such as a visible light base station of a visible light communication system. In step 41, the terminal may operate in an energy saving mode or a normal mode, and the terminal measures the channel quality of the second downlink from the second access network device to the terminal, obtains a measurement result, and reports the measurement result to the first access network device. The downlink of the first access network device to the terminal is referred to as the first downlink and the downlink of the second access network device to the terminal is referred to as the second downlink.

The first access network equipment receives the measurement result, determines the working mode of the terminal (for example, whether a receiving circuit receiving the second downlink needs to enter an energy-saving mode) according to the measurement result and a preset judgment condition, determines and controls the first access network equipment to transmit service data to the terminal through the first downlink, or the second access network equipment to transmit the service data to the terminal through the second downlink, determines the monitoring mode of the terminal on the second downlink, and the like, and further selects a proper measurement configuration for the terminal. The first access network device may then send the selected measurement configuration to the terminal.

And step 42, obtaining the measurement configuration selected by the first access network device for the terminal.

Here, the terminal receives the measurement configuration selected by the first access network device for the terminal, and executes corresponding processing according to the measurement configuration, which may specifically include at least one of the following: setting the working mode of the terminal (for example, whether a receiving circuit for receiving the second downlink needs to enter an energy-saving mode), receiving the service data sent by the first access network equipment through the first downlink, or receiving the service data sent by the second access network equipment through the second downlink, determining the monitoring mode of the terminal for the second downlink, monitoring the link quality of the second downlink according to the determined monitoring mode, and the like.

Through the steps, the embodiment of the invention realizes the measurement configuration of the terminal under the visible light heterogeneous networking and provides support for the energy saving of the terminal. For example, in the case where the second downlink quality is poor, the terminal may be controlled to access the power saving mode to reduce power consumption of a receiving circuit that receives data of the second downlink, and the like.

The above steps are described in more detail below.

A terminal typically includes a first receiving circuit for receiving a first downlink signal and a second receiving circuit for receiving a second downlink signal.

In step 41, the measurement result may be a first measurement result measured when the terminal operates in a normal mode, and the terminal receives downlink data through the second downlink in the normal mode. In step 42, the terminal may receive a first measurement configuration sent by the first access network device, where the first measurement configuration includes at least one of the following:

1) First indication information for indicating the terminal to enter an energy-saving mode;

2) Energy saving mode configuration information;

3) Second indication information for indicating the terminal to receive the first downlink channel data.

Here, the energy saving mode configuration information includes at least one measurement period, and the measurement period includes a non-measurement window and a measurement window adjacent to each other; the non-measurement window includes a first number of time cells in succession and the measurement window includes a second number of time cells in succession.

It should be noted that the energy saving mode configuration information may also be configured on the terminal side in advance, or when the terminal accesses the network, the terminal is configured by the first access network device or the second access network device, and in this case, the first measurement configuration may not include the energy saving mode configuration information.

The terminal entering the energy-saving mode means that the terminal periodically turns off and turns on the second receiving circuit according to the measurement period configured by the energy-saving mode configuration information so as to reduce the receiving power consumption. In the embodiment of the invention, the working modes of the terminal comprise a normal mode and an energy-saving mode. In the normal mode, the terminal receives data sent by second access network equipment through a second receiving circuit; and in the energy-saving mode, the terminal periodically closes and opens the second receiving circuit, and receives data sent by the first access network equipment through the first receiving circuit.

In this way, after step 42, the terminal may enter the energy saving mode according to the first indication information and the energy saving mode configuration information, and turn off the second receiving circuit, and/or switch the receiving circuit of the service data according to the second indication information, that is, receive the service data sent by the first access network device through the first receiving circuit. For example, if the terminal is currently in the energy saving mode when receiving the first measurement configuration, the terminal keeps in the energy saving mode according to the first indication information, and in addition, when the energy saving mode configuration information adjusts configurations such as a measurement period, the terminal may also adjust relevant parameters in the energy saving mode according to the energy saving mode configuration information, such as a duration of the measurement period, a ratio of a non-measurement window in the measurement period to which the terminal belongs, and the like.

As an implementation manner, in the energy saving mode, the terminal enters a sleep state in a non-measurement window in the measurement period, turns off the second receiving circuit, and does not measure the second downlink channel quality; and when the measurement window enters an activated state, starting the second receiving circuit, measuring the quality of the second downlink channel, and reporting the measurement result to the first access network equipment.

Herein, the sleep state or the active state generally refers to an operating state of a second receiving circuit in the terminal that receives a second downlink signal. In the sleep state, the terminal may turn off the portion of the receiving circuit or reduce the operating time of the portion of the receiving circuit to reduce power consumption. In the active state, the terminal may turn on the receiving circuit of the portion to receive data of the second downlink or monitor signal quality of the second downlink.

As another implementation manner, in the power saving mode, the terminal enters a sleep state in a non-measurement window in the measurement period, and does not measure the quality of the second downlink channel; and measuring a received signal strength at a first offset position within the non-measurement window from before the start position of the measurement window, where the received signal strength is a Received Light Strength (RLS) comprising signal light and background light:

if the measured received signal strength is greater than a preset first threshold value, the terminal enters an activated state in the measurement window, measures the quality of the second downlink channel at a second offset position away from the initial position of the measurement window, and sends a second measurement result obtained by measurement to the first access network equipment;

and if the received signal strength is not greater than the first threshold value, the terminal enters a dormant state in a measurement window and does not measure the quality of the second downlink channel, thereby further reducing the receiving power consumption in the activation window of the terminal.

In addition, the first access network device may further adjust a ratio of a non-measurement window in the energy saving mode in the measurement period to which the non-measurement window belongs, and/or adjust a duration of the measurement period, so as to adjust an energy saving effect of the receiving circuit. For example, when the first indication information is used to indicate to enter a first energy saving mode, and a measurement period of the first energy saving mode is a first measurement period, the terminal may further receive first information sent by the first access network device, where the first information is used to indicate that the terminal enters a second energy saving mode, and a measurement period of the second energy saving mode is a second measurement period, where a duration of the second measurement period is greater than a duration of the first measurement period, and/or a proportion of a non-measurement window in the second measurement period is greater than a proportion of a non-measurement window in the first measurement period. The terminal is controlled to enter the energy-saving mode based on the second measurement period, so that the energy-saving effect can be further improved, and the energy consumption of the terminal can be further saved.

In step 41, the measurement result may be a second measurement result obtained by measuring that the terminal operates in an energy saving mode, where the terminal receives downlink data through a first downlink between the terminal and a first access network device in the energy saving mode; in addition, in the energy saving mode, the terminal turns off a receiving circuit for receiving the second downlink at least for a part of time, where the part of time is a part of time during which the terminal operates in the energy saving mode. In step 42, the terminal may receive a second measurement configuration sent by the first access network device, where the second measurement configuration includes at least one of the following:

In this way, after step 42, the terminal may exit the energy saving mode, i.e. turn on the second receiving circuit, according to the third indication information, and switch the receiving circuit of the service data, i.e. receive the service data sent by the second access network device through the second receiving circuit, according to the fourth indication information.

In step 42, the terminal may further receive a third measurement configuration sent by the first access network device, where the third measurement configuration is 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. In addition, after the terminal is disconnected from the second access network device, the second receiving circuit can be closed, so that receiving power consumption is saved.

Referring to fig. 5, when the measurement method provided in the embodiment of the present invention is applied to a first access network device (e.g., a radio frequency base station), the measurement method includes:

step 51, receiving a measurement result of the channel quality of a second downlink sent by the terminal, where the second downlink is a link between the terminal and a second access network device.

Here, the first and second access network devices can provide the terminal with access based on different access modes. For example, the first access network device may be a radio frequency base station of a cellular network and the second access network device may be a visible light base station. The first access network device may receive the measurement result reported by the terminal through a radio frequency uplink.

And step 52, selecting measurement configuration for the terminal according to the measurement result and the judgment condition, and sending the selected measurement configuration to the terminal.

Here, the decision condition may be pre-configured, and specifically may be a correspondence between different second downlink channel qualities and measurement configurations.

Through the steps, the embodiment of the invention can receive the downlink signal quality of the second access network equipment reported by the terminal through the first access network equipment, select and issue the measurement configuration of the terminal according to the downlink signal quality, configure the working state of the second receiving circuit of the terminal and achieve the purpose of saving the power consumption of the terminal.

In step 51, the measurement result may be a first measurement result measured when the terminal operates in a normal mode, where the terminal receives downlink data through the second downlink in the normal mode; in step 52, the first access network device compares the first measurement result with a preset first quality threshold, and selects a measurement configuration for the terminal according to the comparison result.

Specifically, in a case that the first measurement result is worse than a first quality threshold, in a case that the first measurement result is worse than the first quality threshold, a first measurement configuration is sent to the terminal, where the first measurement configuration includes at least one of:

energy saving mode configuration information;

Here, the terminal entering the energy saving mode means that the terminal periodically turns off and turns on the second receiving circuit according to the measurement period configured by the energy saving mode configuration information, so as to reduce receiving power consumption. If the terminal is currently in the energy-saving mode, the first indication information is used for indicating the terminal to continue to be kept in the energy-saving mode, and in addition, relevant parameters of the terminal in the energy-saving mode can be adjusted through the energy-saving mode configuration information.

If the first measurement result is inferior to the first quality threshold, if the second access network device sends data to the terminal currently, or the terminal currently operates in a normal mode, the first access network device may further send a first notification message for instructing to stop sending data to the terminal to the second access network device, and send data to the terminal through a first downlink, where the first downlink is a link between the terminal and the first access network device. Through the processing steps, the embodiment of the invention adjusts the working mode of the terminal (enters the energy-saving mode) under the condition that the downlink quality of the second access network device is poor, and sends data to the terminal through the downlink of the first access network device, thereby improving the reliability of data transmission and saving the receiving power consumption of the terminal.

After the terminal enters the energy saving mode, the terminal may further turn on a second receiving circuit within a measurement window of the measurement period and measure the signal quality of the second downlink, obtain a second measurement result, and report the measurement result to the first access network device. At this time, the first access network device may further receive a second measurement result of the second downlink channel quality obtained by measuring by the terminal in the operating energy saving mode, and perform the following processing according to the second measurement result:

in step 51, the measurement result may be a second measurement result measured when the terminal operates in an energy saving mode, where the terminal receives downlink data through a first downlink between the terminal and a first access network device in the energy saving mode; in addition, in the power saving mode, the terminal turns off a reception circuit that receives the second downlink for at least a part of the time. At this time, in the above step 52, when the second measurement result is better than the 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 for instructing to resume sending data to the terminal to the second access network device, where the second measurement configuration includes at least one of:

Through the above processing, the embodiment of the present invention may resume providing data transmission from the second access network device to the terminal when the quality of the second downlink is better, and control the terminal to exit the energy saving mode to receive the data sent down on the second downlink through the second receiving circuit.

The second quality threshold is more stringent than the first quality threshold, assuming that the second measurement better than the second quality threshold reflects a second signal quality, and the first measurement better than the first quality threshold reflects a first signal quality, typically the second signal quality being better than or equal to the first signal quality.

The embodiment of the invention can also dynamically adjust the configuration of the energy-saving mode so as to further reduce the measurement times or the measurement duration of the terminal in the energy-saving mode and save the measurement power consumption of the terminal on the second downlink in the energy-saving mode. Furthermore, in the case that the quality of the second downlink is always poor, the embodiment of the present invention may disconnect the second downlink.

Here, it is assumed that the first indication information is used to indicate entry into a first energy saving mode, and a measurement period of the first energy saving mode is a first measurement period. As an implementation manner, the first access network device may further start a first timer after sending the first measurement configuration to the terminal.

After the first timer expires, or within consecutive N measurement periods before the first timer expires, not receiving a second measurement result better than the second quality threshold, or, before the first timer expires, receiving a second measurement result worse than a third quality threshold, sending first information to the terminal, where the first information is used to instruct the terminal to enter a second energy saving mode, a measurement period of the second energy saving mode is a second measurement period, where a duration of the second measurement period is greater than a duration of the first measurement period, and/or a proportion of a non-measurement window in the second measurement period is greater than a proportion of a non-measurement window in the first measurement period. Here, N is a preset positive integer. The second measurement result is a measurement result measured when the terminal operates in an energy-saving mode.

It is assumed that the second measurement being inferior to the third quality threshold reflects a third signal quality and the first measurement being inferior to the first quality threshold reflects a fourth signal quality, the third signal quality generally being no better than the fourth signal quality.

Through the above steps, in the embodiment of the present invention, when the signal quality of the second downlink is in a poor quality for a long time, the number of times of measurement in the measurement period is further reduced and/or the measurement duration is reduced, so as to reduce the measurement power consumption of the terminal in the power saving mode.

In addition, after sending the first measurement configuration, the first access network device may further start a second timer, where a timeout time of the second timer is greater than a timeout time of the first timer.

And after the second timer is overtime and the second measurement result superior to the second quality threshold is not received, or before the second timer is overtime and the second measurement result inferior to a fourth quality threshold is received, sending a third measurement configuration to the terminal and sending a third notification message to the second access network equipment, wherein the third measurement configuration is used for indicating the terminal to disconnect from the second access network equipment, and the third notification message is used for indicating the second access network equipment to disconnect from the terminal.

The fifth signal quality is not better than the third signal quality, assuming that the second measurement worse than the third quality threshold reflects a third signal quality and the second measurement worse than the fourth quality threshold reflects a fifth signal quality.

Through the above steps, in the embodiment of the present invention, when the signal quality of the second downlink is in a poor quality for a longer time or the signal quality becomes worse, the connection between the terminal and the second access network device is disconnected, so that the second receiving circuit can be turned off for a long time, the signal quality of the second downlink is not measured any more, and the measurement power consumption of the terminal in the energy saving mode is further reduced.

Referring to fig. 6, when the measurement method provided in the embodiment of the present invention is applied to a second access network device (e.g., a visible light base station), the measurement method includes:

and 61, sending service data to the terminal through a second downlink, where the second downlink is a link between the terminal and a second access network device.

Step 62, receiving a first notification message sent by the first access network device and used for instructing to stop sending data to the terminal, where the first notification message is sent by the first access network device when a first measurement result is inferior to a first quality threshold, and the first measurement result is a measurement result of a second downlink channel quality measured by the terminal operating in a normal mode; and the terminal receives downlink data through the second downlink in the normal mode.

And step 63, according to the first notification message, stopping sending the data to the terminal through the second downlink.

Through the steps, the embodiment of the invention realizes that the first access network equipment adjusts the sending link of the terminal data according to the measurement result of the signal quality of the two downlinks, so that the terminal can enter an energy-saving mode to reduce the receiving power consumption of the terminal.

Similarly, the second access network device may further receive a second notification message sent by the first access network device and used for instructing to resume sending data to the terminal, where the second notification message is sent by the first access network device when a second measurement result is better than a second quality threshold, and the second measurement result is a measurement result of a second downlink channel quality measured by the terminal in the power saving mode; and then according to the second notification message, resuming to send the data to the terminal through the second downlink.

The second access network device may further receive a third notification message sent by the first access network device and used for instructing the second access network device to disconnect from the terminal; and then according to the third notification message, disconnecting the connection with the terminal.

The above method of the present invention is described in detail by taking a radio frequency base station (first access network device) and a visible light base station (second access network device) as examples, and by taking more specific examples. In the following example, the second downlink is a visible light downlink, and the first downlink is a radio frequency downlink.

Referring to fig. 7, an example of a trigger condition and an effective time for a terminal to enter an energy saving mode is provided:

s1, the terminal receives the visible light downlink signal and measures the received visible light downlink signal.

Here, the visible light downlink signal may be a visible light reference signal.

And S2, the terminal feeds back the measured visible light downlink signal intensity to the radio frequency base station through the uplink radio frequency link.

Here, the visible light downlink signal strength may be RSRP/RSRQ or the like.

And S3, the radio frequency base station compares the received signal intensity with a threshold value, and if the signal intensity is greater than or equal to a first threshold value, the radio frequency base station informs the visible light base station that the downlink signal sending configuration is unchanged or is not processed, and then the steps S4 to S5 are carried out. Steps S4 to S5 are similar to steps S1 to S2 described above.

S61-S62, the radio frequency base station compares the received signal strength with a threshold value, and if the signal strength is less than a first threshold value, the radio frequency base station starts downlink data transmission, informs the visible light base station to stop data transmission, and informs the terminal to enter an energy-saving mode and receive data through the radio frequency base station, and the next time unit (time slot/transmission opportunity, etc.) takes effect (S7).

Specifically, the radio frequency base station can inform the visible light base station whether to update visible light downlink signal transmission or not by sending a 1-bit signaling, if so, the visible light base station indicates that the visible light downlink signal transmission is not needed to be updated, and the visible light continues to perform downlink data transmission; if yes, the visible light base station needs to enter an energy-saving mode, stop downlink data transmission, and update downlink signal sending configuration in the next time unit.

Referring to fig. 8, an example of a measurement behavior of a terminal power saving mode is provided, including:

and the terminal receives an energy-saving mode starting signaling sent by the downlink radio frequency link, the next time unit takes effect, and the terminal enters a first energy-saving monitoring period.

a) The first energy-saving monitoring period refers to a first measurement period of a visible light downlink measurement reference symbol;

b) The first measurement period comprises a measurement window and a non-measurement window, wherein in the measurement window, the terminal starts to monitor the visible light downlink signal intensity from a first offset position, in the non-measurement window, the terminal closes the visible light downlink receiving circuit and enters a dormant state, and the visible light downlink signal intensity is not monitored so as to reduce power consumption;

c) A first number of consecutive time units in a non-measurement window (sleep period) from the start of the first measurement period; after the terminal wakes up from the sleep state, the terminal continuously stays in a measurement window (activation period) for a second number of time units, and the terminal starts to monitor the downlink signal intensity of the visible light from the first offset position; the duration and offset configuration may be carried in the energy saving mode activation signaling or may be a default configuration.

d) To further reduce power consumption, the terminal wakes up at a 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 value, the terminal detector can receive the signal light, and the terminal wakes up in a measurement window to measure the signal intensity (2-level measurement); if the received light intensity is smaller than the second threshold value, the terminal detector cannot receive the signal light, the terminal also sleeps in the measurement window, and the visible light downlink receiving circuit is closed.

e) When the signal strength is measured in the active period, the measurement can be carried out on all the sub-channels in the frequency domain; considering that the frequency response characteristics of visible light on different channels are different, the measurement can be performed on partial sub-channels/BWPs with good frequency response characteristics; the portion of the sub-channels may or may not be contiguous.

Referring to fig. 9, another example of the measurement behavior of the terminal power saving mode is provided, which includes:

and starting the first timer and the second timer while the energy-saving mode is effective, and executing 2-level period setting when certain conditions are met.

a) If the terminal does not execute the level 2 measurement after the first measurement period of the first quantity or the first timer is overtime or the measured visible light downlink signal intensity is too poor, the radio frequency base station sends a measurement period switching indication signaling.

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

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

i. The duration of the second measurement period can be directly configured, and can also indicate a scaling coefficient alpha; the second measurement period is longer than the first measurement period, and since the first period which lasts for the first number or the timer is not awakened after timeout, which indicates that the visible light signal intensity is weak and cannot be recovered temporarily, the terminal may enter another room, and considering the moving process of the terminal, the power consumption can be further reduced by lengthening the sleep period;

and ii, the measuring window and the non-measuring window can be directly configured, the duration and the position of the measuring window can be defaulted to be unchanged, and only the duration of the second measuring period is configured.

The level 2 measurement configuration is unchanged.

The frequency domain monitoring configuration is unchanged.

Referring to fig. 10, an example of the turn-off condition of the terminal power saving mode is provided, which includes:

1. in the second timer, in the measurement window of any measurement period, as long as the signal intensity of any visible light base station is measured to be greater than or equal to the first threshold value, the radio frequency base station informs the target visible light base station to start downlink data transmission, and informs the terminal to end the energy-saving mode, and the next time unit takes effect; and if the signal intensity is smaller than the first threshold value, the terminal is not processed and is continuously in the energy-saving mode.

2. And after the second timer is overtime, the connection with the visible light is disconnected.

It can be seen from the above examples that, in the embodiments of the present invention, when the terminal selects the radio frequency downlink communication and simultaneously monitors the quality of the downlink signal of the visible light, the visible light receiving circuit is turned off in the sleep period, and the monitoring is performed only in the activation period, so as to reduce the power consumption of the terminal; in addition, the terminal only measures in the active period, and the relevant configuration of the energy saving mode may multiplex a Measurement Timing Configuration (MTC) configuration, including a measurement window period, a duration measured by each frequency carrier, a timing offset, and the like, thereby reducing signaling overhead.
