[0035] The concepts, nouns or terms involved in the embodiments of the present application are explained below.

[0036] 1. Radio Resource Management (RRM)

[0037] The purpose of radio resource management is to provide high-quality service quality assurance for terminals under limited bandwidth conditions. RRM is based on the measurement (reporting) of radio resources by terminals. Network-side equipment flexibly allocates and dynamically adjusts radio (transmission) resources for terminals, thereby maximizing the utilization of radio spectrum, preventing network congestion and keeping the signaling load as small as possible.

[0038] RRM measurement is a basic function in mobile communication systems. The base station performs operations such as mobility management and carrier management based on the RRM measurement mechanism. RRM measurement includes measurement configuration, measurement execution and measurement reporting.

[0039] Specifically, the base station configures a measurement object (MO) list, a report configuration (ReportConfig) list and a measurement identity (MeasId) list. Each measurement identity (MeasId) is configured to link a measurement object with a measurement report configuration (ReportConfig).

[0040] Among them, each MeasId can be considered as a "measurement task". For example, the base station can link more than one MO to the same ReportConfig by configuring multiple MeasIds, and can also link multiple ReportConfigs to the same MO. A measurement report configuration is used to configure the trigger-related parameters and reporting-related parameters of the measurement report, that is, under what circumstances to report the measurement report and what content to report in the measurement report. The above parameters may include report types, such as periodic reporting, event-triggered reporting, etc. Typical event-triggered reporting includes the following:

[0041] Event A1 (Serving becomes better than threshold): the serving cell signal is better than the threshold;

[0042] Event A2 (Serving becomes worse than threshold): the serving cell signal is worse than the threshold;

[0043] Event A3 (Neighbour becomes offset better than SpCell) means: the neighbor cell signal is better than the SpCell signal by an offset;

[0044] Event A4 (Neighbour becomes better than threshold): the neighboring cell signal is better than the threshold;

[0045] Event A5 (SpCell becomes worse than threshold1 and neighbour becomes better than threshold2) means: the SpCell signal is worse than threshold 1, and the neighbor cell signal is better than threshold 2;

[0046] Event A6 (Neighbour becomes offset better than SCell): The neighboring cell signal is better than the SCell signal by an offset;

[0047] Event B1 (Inter RAT neighbour becomes better than threshold): the signal of the neighboring cell of the different system is better than the threshold;

[0048] Event B2 (PCell becomes worse than threshold1 and inter RAT neighbour becomes better than threshold2) means: the PCell signal is worse than threshold 1, and the inter-RAT neighbor signal is better than threshold 2.

[0049] Specifically, after receiving the measurement configuration, the UE measures the frequency point specified by each MO in the measurement object list to obtain the measurement value of (one or more) cells on the frequency point. Among them, one measurement object corresponds to one measurement frequency point, and the UE measures the reference signal corresponding to the cell at the frequency point, such as SSB, cell reference signal, CSI-RS, etc., to obtain the measurement value of the cell at the frequency point.

[0050] Furthermore, if the MO is associated with event trigger reporting (i.e., there is a MeasID, the MeasID corresponds to the MO, and the report type of the ReportConfig corresponding to the MeasID is event trigger reporting), the UE determines whether there is a cell signal at the frequency point that meets the entry conditions of the event. If the entry conditions are met, the UE starts the TTT (Time To Trigger) timer. Since the cell signal may fluctuate up and down, the TTT timer is running during the observation period to observe whether the cells that meet the event entry conditions meet the entry conditions for a continuous period of time.

[0051] 2. Time To Trigger (TTT)

[0052] TTT means that a specific measurement event is reported only when the triggering condition of the event is always satisfied within a period of time.

[0053] TTT specifies the range of values ​​for the trigger time parameter, which refers to the time that the event-specific conditions need to be met in order to trigger a measurement report. A value of ms0 corresponds to 0 milliseconds and applies to the behavior specified in 7.1.2; a value of ms40 corresponds to 40 milliseconds, and so on.

[0054] Specifically, if the cell meets the entry conditions of the event all the time during the TTT, the UE triggers the reporting of the measurement report of the MeasId after the TTT timer expires. The measurement report carries the ID of the cell and the measurement value of the cell. The base station performs operations such as handover based on the measurement report.

[0055] The following describes the process of UE reporting measurement events based on TTT:

[0056] S1. Receive measurement configuration.

[0057] S2. Measure the frequency points configured in the measurement configuration to obtain the measurement value of the cell;

[0058] S3, confirm that the measurement value of the cell meets the entry condition of the event, and start the TTT timer;

[0059] S4. During the TTT operation, the measured values ​​of the cell always meet the entry conditions;

[0060] S5. TTT times out, triggering a measurement report, which carries the cell ID and measurement value.

[0061] 3. Ambient IoT

[0062] Ambient IoT is a new 3GPP IoT technology to be studied. Ambient IoT terminals have ultra-low complexity and ultra-low power consumption.

[0063] Ambient IoT, also known as ambient power-enabled Internet of Things (Ambient power-enabled IoT), is an IoT service in which IoT terminals are powered by energy harvesting. IoT terminals do not have batteries or have limited energy storage capabilities (for example, using a capacitor). Energy sources for energy harvesting include radio waves, light, motion, heat, or other suitable energy sources.

[0064] It can be understood that low-power IoT devices are IoT devices with low overall power consumption, including low-power signal reception and low-power signal transmission. Due to the low overall power consumption, the energy for communication can come from the environment, such as wind energy, kinetic energy, thermal energy, RF signals, etc., and can also be called Ambient IoT or passive IoT devices, answering devices.

[0065] The following is an explanation of how Ambient IoT devices send signals:

[0066] Ambient IoT devices can transmit signals by backscattering RF signals; such devices are also called electronic tags, radio frequency tags (RFID);

[0067] Some active tags have the ability to generate active signals, but in order to achieve low power consumption of the device, it is generally lower than 0 dBm, for example, less than or equal to -10 dBm.

[0068] The following describes the types of Ambient IoT devices:

[0069] Ambient IoT terminals can be classified based on energy source, energy storage capability, passive or active transmission, etc. It includes the following three types of devices:

[0070] Device Type A: Passive Device. This type of Ambient IoT device has no energy storage and no independent signal generation / amplification, that is, backscatter transmission.

[0071] Device Type B: Semi-passive Device. This type of Ambient IoT device has energy storage and no independent signal generation, i.e. backscatter transmission. The use of stored energy can include amplification of reflected signals.

[0072] Device Type C: Active Device. This type of ambient IoT device has energy storage and independent signal generation, that is, active RF components for transmission.

[0073] 4. Backscatter Communication (BSC)

[0074] Backscatter communication refers to the use of radio frequency signals from other devices or the environment to modulate the signal to transmit its own information. Backscatter technology is a passive or low-energy technology. Its technical feature is that it can complete the transmission of its own signal by changing the characteristics of the received environmental radio frequency signal, such as phase or amplitude information, to achieve extremely low power or zero power information transmission.

[0075] A method of backscatter transmission based on OOK is described as follows:

[0076] A simple implementation method is that when a radio frequency tag (tag) needs to send a '1', the tag reflects the incident carrier signal, and when the tag needs to send a '0', it does not reflect.

[0077] Specifically, the backscatter communication device controls the reflection coefficient Γ of the circuit by adjusting its internal impedance, thereby changing the amplitude, frequency, phase, etc. of the incident signal to achieve signal modulation. The reflection coefficient of the signal can be characterized as:

[0078] Γ=(Z_1-Z_0) / (Z_1+Z_0)=|Γ|e^(jθ_T)

[0079] Where Z_0 is the antenna characteristic impedance and Z_1 is the load impedance. Assuming the incident signal is S_in(t), the output signal is S_out(t) = S_in(t)|Γ|e^(jθ_T). Therefore, by properly controlling the reflection coefficient, the corresponding amplitude modulation, frequency modulation or phase modulation can be achieved.

[0080] It should be noted that the reception of such equipment is usually low-power, and generally uses low-power RF, IF, or baseband envelope detection to receive signals. The waveform of the transmitted signal usually uses simple modulation methods, such as OOK, ASK, FSK and other simple modulation methods.

[0081] The device that communicates with such low-power devices is called a read-write device, which may be, for example, a terminal, a base station, or a device with read-write functions, such as a reader / writer, and the specifics are not limited here.

[0082] 5. A-IoT data / service types

[0083] 3GPP R19 A-IoT studies the following data / service types:

[0084] DO:Device-Originated

[0085] DT: Device-Terminated

[0086] DO-A Device-Originated–Autonomous

[0087] DO-DTT Device-Originated–Device-Terminated Triggered

[0088] Among them, DO and DT data indicate that the data flow originates from A-IoT devices (similar to RFID tags) or is transmitted to A-IoT devices. For data flows originating from A-IoT devices, i.e. DO data, it can be further divided into the following two categories:

[0089] DO-A (Device-Originated Autonomous) means that the device initiates data transmission autonomously, such as connecting a large number of various sensors that collect and actively report information about the environment, equipment, and organisms when necessary.

[0090] DO-DTT (Device-Originated–Device-Terminated Triggered), that is, the device initiates data transmission after being triggered by the network. For example: asset identification, status reporting and tracking are all DL triggered reports, and the reader collects data from the tag by triggering the inventory program. Since the data is generated / initiated in the IoT device, this service should be regarded as a command sent by the reader to trigger the tag to initiate a DO service.

[0091] 6. Information transmission between Reader and Tag in RFID

[0092] RFID is a traditional backscatter communication system, whose main design goal is to identify the ID and read the data of BSC devices (i.e. tags) within the coverage of the reader. Since RFID was originally used in the automated inventory of large quantities of goods, the process of identifying tags and reading data is also called inventory.

[0093] Taking the EPC C1G2 RFID system defined in ISO 18000-6c as an example, after the reader sends a query command (Query), the Tag responds (Reply). Taking the Reply as RN16 as an example, the Tag generates a 16-bit random number sequence and sends it to the reader. Then the reader sends the random number sequence to the Tag through the ACK command. After the Tag successfully verifies the RN16 in the ACK, it sends the subsequent data (such as PC / XPC, EPC, etc.) to the reader.

[0094] The instructions for Reader operation are shown in Table 1 below:

[0095]

[0096] Table 1

[0097] The status of the Tag tag is shown in Table 2 below:

[0098]

[0099]

[0100] Table 2

[0101] The goal of 3GPP Ambient IoT is to provide large-scale cellular network deployment and seamless coverage. In the scenario where the A-IoT device is covered by the network device, after the A-IoT device sends an uplink signal to the network device, if the network coverage is poor, the uplink signal will not be successfully sent to the network device. If the A-IoT device continues to reside in the cell under the network device, the subsequent uplink signal will still not be sent successfully, making the A-IoT device unable to perform services normally. Furthermore, if the A-IoT device's uplink signal cannot be successfully sent to the network device, if the A-IoT device continues to send uplink signals to the network device, it will interfere with the system.

[0102] The measurement method A-IoT device provided in the embodiment of the present application can determine whether to report measurement auxiliary information for measuring the A-IoT device to the network device according to the network configuration, so as to assist the network device in measuring the A-IoT device, or the A-IoT device can perform A-IoT measurement or measurement reporting according to the network configuration. In this way, the channel environment quality between the A-IoT device and the network device can be obtained through A-IoT measurement, so that when the signal environment quality is poor, such as poor network coverage, the device can reside in a cell with better signal quality, thereby improving communication performance.

[0103] The following describes the measurement method provided in the embodiment of the present application in detail through some embodiments and their application scenarios in combination with the accompanying drawings.

The A-IoT device has a power amplification capability, and after receiving the signal from the first network device, it can perform power amplification and backscatter and send data to the first network device. For example, the A-IoT device is a semi-passive device, and the A-IoT device backscatters the signal from the network device to the network device.

[0129] Exemplarily, the power amplification value may be static or dynamic. For example, the A-IoT device may report a fixed power amplification value to the first network device, or the A-IoT device may report the power amplification value to the first network device in real time or periodically.

[0130] Exemplarily, the reflection gain may be the reflection loss value in the measurement auxiliary information, or the reflection gain may be the sum of the power amplification value and the reflection loss value. It can be understood that in the above calculation process, the reflection gain and the reflection loss value may be defined as negative values.

[0131] It should be noted that since the amplification capability of the A-IoT device may vary due to the influence of energy storage, the reported power amplification value may be a fixed value or a variable value.

[0154] Exemplarily, the excitation signal may be a continuously transmitted wireless signal, also known as a continuous wave. According to the strength of the excitation signal, the energy collection state of the A-IoT device or the time required for energy collection may be calculated.

[0157] In an embodiment of the present application, the first network device may send an excitation signal or a synchronization signal according to the measurement window information, so that the first network device can intermittently send the excitation signal or the synchronization signal, thereby reducing device power consumption.

The inventory request may carry indication information indicating the execution of measurement, and the A-IoT device may perform measurement during the execution of the inventory according to the indication information.

[0201] It should be noted that inventory refers to the process of identifying the ID of radio frequency tags within the coverage of the reader in the RFID system to count the radio frequency tags. The A-IoT device in the embodiment of the present application may also be referred to as an electronic tag or a radio frequency tag. The inventory in the embodiment of the present application is the process of counting the A-IoT devices.

[0202] In an embodiment of the present application, the A-IoT device can measure the signal from the measurement object during the inventory period according to the measurement information configured by the network device, thereby improving the utilization rate of wireless resources.

[0203] In some embodiments, the measurement configuration information includes third configuration information. Figure 2 ,like Figure 5As shown, the measurement method provided in the embodiment of the present application further includes the following steps S205:

[0204] Step S205: The A-IoT device reports the first measurement result to the first network device according to the third configuration information.

[0205] The first measurement result is a result of performing A-IoT measurement on a measurement signal from the second network device.

[0206] It should be noted that the explanation of the third configuration information can be found above and will not be repeated here.

[0207] In some examples, the first measurement result includes at least one of the following:

[0208] Received signal strength;

[0209] Reference signal received power RSRP;

[0210] Reference Signal Reception Quality RSRQ.

[0211] Exemplarily, the above-mentioned received signal strength may be the strength of a signal received by the A-IoT device from the first network device.

[0212] Exemplarily, the RSRP may be the RSRP of a serving cell in which the A-IoT device resides.

[0213] Exemplarily, the above RSRQ may be the RSRQ of the serving cell where the A-IoT device resides.

[0214] In some examples, the first measurement result is a measurement result within a valid time, or a measurement result during an inventory period or a data transmission period.

[0215] In some examples, the first measurement result may be sent in at least one of periodic reporting and event-triggered reporting.

[0216] The following is an example of a process in which the A-IoT device reports measurement results, taking the first network device as a network device serving as a reader / writer for the A-IoT device and the second network device also as a network device serving as a reader / writer for the A-IoT device as an example.

[0217] For ease of description, in the embodiment of the present application, the network device that serves as a service reader / writer for the A-IoT device is referred to as a reader / writer.

[0218] Exemplarily, in combination with the above embodiment, the A-IoT device measures the signal from the reader / writer, obtains the signal strength value of the signal, and then reports the signal strength value to the reader / writer. Exemplarily, the above signal can be at least one of an excitation signal, a synchronization signal, and a downlink command.

[0219] The following is an example of a process in which the A-IoT device reports measurement results, taking the first network device as a network device serving as a reader / writer of the A-IoT device and the second network device as a network device adjacent to the network device (i.e., an adjacent reader / writer) as an example.

[0220] Exemplarily, in combination with the above embodiment, the A-IoT device measures the signal from the adjacent reader / writer, obtains the signal strength value of the signal, and then reports the signal strength value to the reader / writer. Exemplarily, the above signal can be at least one of an excitation signal, a synchronization signal, and a downlink command.

[0221] Exemplarily, the A-IoT device may periodically report (Periodic Reporting) measurement results, thereby facilitating monitoring of signals (such as excitation signals) sent by the network; or, the A-IoT device may report measurement results based on event triggers (Event-Trigger Reporting), thereby facilitating monitoring of the movement of the A-IoT device.

[0222] It should be noted that the above reporting method can be applicable to A-IoT devices with reporting capabilities, such as active A-IoT devices.

[0223] In some embodiments, after the A-IoT device reports the first measurement result to the first network device according to the third configuration information, the first network device may receive the first measurement result from the A-IoT device.

[0224] In an embodiment of the present application, the A-IoT device can measure the signal from the network device or the network device adjacent to the network device according to the measurement information configured by the network device, and report the obtained measurement results according to the network configuration, so that the network device can be aware of the network coverage, avoid the A-IoT device responding to the network device with weaker coverage, and thereby reduce interference within the system.

[0225] In some embodiments, the A-IoT device may report the first measurement result to the first network device upon receiving a trigger signal from the first network device.

[0226] The trigger signal is used to trigger the A-IoT device to send the measurement result.

[0227] In some examples, the trigger signal may be a signal dedicated to triggering the A-IoT device to send a measurement result.

[0228] Exemplarily, the A-IoT device receives a trigger signal from the first network device, determines whether a measurement reporting condition is met, and reports the first measurement result to the first network device if the measurement reporting condition is met.

[0229] The measurement reporting conditions include at least one of the following:

[0230] Reaching the reporting period;

[0231] A timer for controlling the periodic reporting of measurement results;

[0232] The measurement reporting event is triggered.

[0233] Exemplarily, the above reporting period may be preconfigured or configured for the network device.

[0234] Exemplarily, the above measurement reporting event may be a measurement reporting event configured by the network device.

[0235] In combination with the above embodiments, in some embodiments, before the above step S205, the following step S206 is also included, and the above step S205 may include the following step S205a.

[0236] Step S206: The first network device sends a trigger signal to the A-IoT device.

[0237] The trigger signal is used to trigger the A-IoT device to send the measurement result.

[0238] Step S205a: When the A-IoT device receives the trigger signal from the first network device, the A-IoT device reports the first measurement result to the first network device according to the third configuration information.

[0239] Exemplarily, taking the first network device as a reader / writer, after the reader / writer sends a trigger signal to the A-IoT device, the measurement result is reported to the first network device according to the measurement reporting related configuration configured by the reader / writer.

[0240] It should be noted that step S206 may be executed before, after or simultaneously with step S201.

[0241] In some embodiments, the above step S205a may include the following steps S205a1:

[0242] Step S205a1: When the A-IoT device receives the trigger signal and the measurement reporting condition is met, the A-IoT device reports the first measurement result to the first network device according to the third configuration information.

[0243] It should be noted that the explanation of the measurement reporting conditions can be found above and will not be repeated here.

[0244] Exemplarily, taking the first network device as a reader / writer, after the reader / writer sends a trigger signal to the A-IoT device, the A-IoT device can determine whether the measurement reporting conditions are currently met, and if the measurement reporting conditions are met, report the measurement results to the first network device according to the measurement reporting related configuration configured by the reader / writer.

[0245] In an embodiment of the present application, the A-IoT device can report the measurement results to the first network device according to the measurement reporting information configured by the network when receiving a trigger signal from the network device, so that passive A-IoT devices that are unable to actively send uplink signals can report the measurement results through the trigger of the first network device.

[0246] In some embodiments, upon receiving a first inventory command from the first network device, the A-IoT device may report the first measurement result to the first network device during the inventory process, or report the first measurement result to the first network device when reporting the inventory result.

[0247] Exemplarily, the first inventory command includes a measurement reporting instruction, and the measurement reporting instruction is used to instruct the A-IoT device to report the measurement result during the inventory process or when reporting the inventory result.

[0248] Exemplarily, upon receiving a first inventory command from the first network device, the A-IoT device may report the first measurement result to the first network device during the inventory process according to the measurement reporting indication, or report the first measurement result to the first network device when reporting the inventory result.

[0249] In combination with the above embodiments, in some embodiments, before the above step S205, the following step S207 is also included, and the above step S205 may include the following step S205b.

[0250] Step S207: The first network device sends a first inventory command to the A-IoT device.

[0251] Step S205b: The A-IoT device reports the first measurement result to the first network device during the inventory process according to the third configuration information, or reports the first measurement result to the first network device when reporting the inventory result.

[0252] In some embodiments, the third configuration information may be included in the first inventory command, and the third configuration information may include a measurement reporting indication; or, the third configuration information and the measurement reporting indication may both be included in the first inventory command, and the measurement reporting indication may not be included in the third configuration information.

[0253] Exemplarily, the first inventory command may be a command sent by the first network device to the A-IoT device to execute an inventory.

[0254] In some embodiments, the third configuration information may not be included in the first inventory command. For example, the third configuration information is configured before the inventory process.

[0255] The following uses the first network device and the second network device as network devices serving as service readers and writers of the A-IoT device as an example to exemplify the process of the A-IoT device reporting the measurement results.

[0256] Exemplarily, in combination with the above embodiment, the A-IoT device measures the synchronization signal from the reader during the inventory, obtains the signal strength value of the synchronization signal, and then reports the signal strength value to the reader during the inventory process, or reports the signal strength value to the reader when reporting the inventory result. For example, the A-IoT device can report the signal strength value in a message reporting the inventory result.

[0257] In an embodiment of the present application, the first network device may carry configuration information (i.e., third configuration information) for configuring measurement reporting in the inventory command, and the configuration information may include a measurement reporting indication. The A-IoT device may report the measurement results to the first network device during the inventory period or when reporting the inventory results, based on the measurement reporting-related configuration and the measurement reporting indication, thereby improving the utilization rate of wireless resources.

[0258] In some embodiments, the present application provides a measurement method, such as Figure 6 As shown, the measurement method may include the following steps S208 to S211:

[0259] Step S208: The first network device sends a first signal to the A-IoT device.

[0260] Step S209: The A-IoT device sends a second signal to the first network device.

[0261] The second signal is a signal obtained by the A-IoT device after backscattering the first signal sent by the first network device.

[0262] Step S210: The first network device performs A-IoT measurement on the second signal from the A-IoT device to obtain a first received signal strength of the first network device.

[0263] Step S211: the first network device calculates a second measurement result according to the first received signal strength and the measurement auxiliary information.

[0264] It should be noted that the above steps 208 to S211 may be performed before the above step 201, or after the above step 201, or simultaneously with the above step 201.

[0265] In some embodiments, the first network device may first send a first signal to the A-IoT device, and the A-IoT device receives the first signal and sends a second signal to the first network device via backscatter communication.

[0266] In some embodiments, the backscatter communication method satisfies the following formula (1):

[0267] Tx-Power-nw – PathlossDL – ReflectionLoss + Amplification –PathlossUL = RSRPnw (1)

[0268] In the above formula (1), Tx-Power-nw represents the transmission power of the first network device, PathlossDL represents the downlink path loss, PathlossUL represents the uplink path loss, ReflectionLoss represents the reflection loss value, Amplification represents the power amplification value, and RSRPnw represents the signal strength received by the first network device.

[0269] It should be noted that due to the reciprocity of the channel, it can be considered that the channel fading experienced by the transmission signals of the uplink channel and the downlink channel is the same, so the downlink path loss can be considered to be the same as the uplink path loss, and both the uplink path loss and the downlink path loss can be expressed by Passloss.

[0270] According to formula (1), the signal strength received by the first network device is equal to the transmit power of the first network device minus the downlink path loss and the reflection loss value, plus the power amplification value, minus the uplink path loss.

[0271] Combining the above formula (1), we can get the path loss calculation formula (2):

[0272] Pathloss = 1 / 2 * (Tx-Power-nw – ReflectionLoss + Amplification –RSRPnw) (2)

[0273] According to the above formula (1) and formula (2), the calculation formula (3) of the received signal strength of the A-IoT device can be obtained:

[0274] RSRP-Device = Tx-Power-nw – Pathloss (3)

[0275] In formula (3), RSRP-Device represents the received signal strength of the A-IoT device, for example, the strength of the signal received by the A-IoT device from the first network device, or the reference signal received power, or the reference signal received quality, etc.

[0276] It can be understood that the strength of the signal received by the A-IoT device from the first network device is approximately equal to the difference between the transmission power of the first network device and the path loss (such as the downlink path loss). After the path loss value is calculated by formula (2), since the transmission power of the first network device is known, the received signal strength of the A-IoT device can be calculated based on the transmission power of the first network device and the path loss value.

[0277] It can be understood that the reflection loss value in the above formula is a positive value. Accordingly, the reflection gain ReflectionGain is calculated according to the following formula (4):

[0278] ReflectionGain=Amplification–ReflectionLoss. (4)

[0279] In some embodiments, the first received signal strength is the strength of the second signal received by the first network device.

[0280] In some embodiments, the above-mentioned measurement auxiliary information may be information reported by the A-IoT device to the first network device, or the above-mentioned measurement auxiliary information may be information pre-configured by the first network device.

[0281] Exemplarily, when the A-IoT device does not report measurement auxiliary information, reflection loss value or power amplification value, the reflection loss value or the power amplification value may adopt a default value, or the reflection loss value or the power amplification value may be 0.

[0282] In some embodiments, the second measurement result includes at least one of the following:
