[0004] In related technologies, New Radio (NR) systems require terminals to periodically perform Radio Resource Management (RRM) measurements in the idle or inactive state. RRM measurements are performed by the master receiver based on the Synchronization Signal Block (SSB).

[0005] With the introduction of a Low Power Wake-Up Radio (LP-WUR), the power consumption of the LP-WUR receiver is much lower than that of the main receiver. Therefore, the performance measurement of the serving cell can be offloaded to the LP-WUR, while the main receiver no longer performs periodic serving cell measurements, or the main receiver performs serving cell measurements based on relaxed performance measurement requirements. However, related technologies do not provide a scheme for measurement via LP-WUR, thus making it impossible to implement measurement via LP-WUR. Summary of the Invention

[0032] A low-power wake-up receiver, also known as a low-power wake-up radio (LP-WUR) or near-zero-power wake-up radio (AZP-WUR), works on the principle that the terminal receiver comprises a first module and a second module, as shown in Figure 2. The first module is the main communication module, used for transmitting and receiving mobile communication data, while the second module is a low-power receiver module (also called a low-power wake-up receiver module), used to receive the wake-up signal. In power-saving mode, the terminal activates the low-power receiver module to listen for the low-power wake-up signal (LP-WUR), while the main communication module is off or in sleep mode. When downlink data arrives, the network-side device sends a wake-up signal to the terminal. After the terminal detects the wake-up signal through the low-power receiver module, it triggers the main communication module to either turn on or be woken up after a series of checks. At this time, the low-power receiver module transitions from an active state to a shutdown or sleep state. The low-power wake-up receiver module can be continuously or intermittently activated, and when activated, it can receive the low-power wake-up signal.

[0033] To reduce receiving activity in standby mode and effectively shut down the radio frequency (RF) and modem modules, thereby significantly reducing power consumption during communication reception, this can be achieved by introducing a near-zero power receiver into the terminal's receiver module. This near-zero power receiver eliminates the need for complex RF module signal detection (such as amplification, filtering, quantization, etc.) and modem signal processing, relying solely on passive matched filtering and low-power signal processing.

[0034] On the base station side, by triggering a wake-up signal on demand, the receiver with near-zero power can be activated to receive the activation notification, thereby triggering a series of processes within the terminal, such as turning on the radio frequency transceiver and baseband processing modules.

[0035] These wake-up signals are typically simple on-off keying signals, the time-domain representation of which is shown in Figure 3. The receiver can then detect the wake-up notification through simple energy detection and subsequent sequence detection and recognition. Furthermore, while the terminal activates its low-power wake-up receiver to receive the wake-up signal, the main receiver module can enter sleep mode or shut down to maintain a low power consumption level, thus saving power by receiving the wake-up signal. The wake-up signal can also warn the receiver of the presence of physical downlink control channel transmission or other communication.

[0036] In addition, low-power wake-up receivers can use low-power synchronization signals (LP-SS) for performance measurements, such as LP-SS reference signal received power (RSRP) or LP-SS reference signal received quality (RSRQ).

[0037] In related technologies, NR systems require terminals to periodically perform RRM measurements during idle / inactive periods. RRM measurements are performed using the master receiver based on SSB.

[0038] With the introduction of LP-WUR, the performance measurement of the serving cell can be offloaded to LP-WUR, while the main receiver no longer performs periodic serving cell measurements; or the main receiver performs serving cell measurements based on relaxed performance measurement requirements. As mentioned earlier, because the receiver power consumption of LP-WUR is much lower than that of the main receiver, the above method can achieve the goal of terminal power saving. However, related technologies do not provide a scheme for measurement via LP-WUR, thus making it impossible to perform measurements via LP-WUR.

[0039] To address the aforementioned issues, this application provides a measurement method for performing measurements via LP-WUR.

[0040] The measurement method provided in this application will be described in detail below with reference to the accompanying drawings, through some embodiments and application scenarios.

[0041] Figure 4 shows a schematic flowchart of a measurement method according to an embodiment of this application. This method 400 can be executed by a terminal. In other words, the method can be executed by software or hardware installed on the terminal. As shown in Figure 4, the method may include the following steps.

[0042] S410, the terminal performs X target measurements on the low-power measurement signal within a time window of I-DRX length using LP-WUR to obtain the first measurement value.

[0043] In the embodiments of this application, X is an integer greater than 0.

[0044] In this embodiment of the application, the terminal can use LP-WUR to perform X target measurements within a window that is equivalent to the length of I-DRX (i.e., the time length of the I-DRX period) or other specific lengths, such as multiples of the I-DRX period. For example, X LP-SS samples can be measured.

[0045] In this embodiment of the application, after performing X target measurements on the low-power measurement signal, X second measurement values ​​can be obtained. In S412, the terminal can use any one of the X second measurement values ​​as the first measurement value, or the terminal can filter the X second measurement values ​​to obtain the first measurement value. For example, the average value of the X second measurement values ​​can be calculated and the average value can be used as the first measurement value. By filtering the X second measurement values ​​to obtain the first measurement value, the situation of misjudgment due to inaccurate measurement can be avoided.

[0046] In one alternative implementation, the target measurement may include at least one of the following: serving cell measurement, stationary cell measurement, co-frequency measurement, and asynchronous measurement.

[0047] In one optional implementation, the measured value obtained by measuring the low-power measurement signal can be RSRP or low-power RSRP (LP-RSRP), or RSRQ or low-power RSRQ (LP-RSRQ), and the specific implementation is not limited in this application.

[0048] In one optional implementation, the low-power measurement signal may include at least one of the following:

[0049] 1) Beacon; wherein the beacon may include at least one of the following: sequence signal, cell ID, time information, and some system information.

[0050] 2) LP-SS; for example, a synchronization signal sequence.

[0051] 3) LP-WUS. The LP-WUS may include at least one of the wake-up information of the sequence signal.

[0052] S412, if the first measurement value meets the exit condition for exiting target measurement using LP-WUR, the terminal wakes up the main receiver and performs target measurement through the main receiver.

[0053] In the embodiments of this application, when the exit conditions are met, such as when the terminal leaves the LP-WUR coverage area or when there is a paging, the LP-WUR can wake up the main receiver in time. The main receiver can perform performance measurements of the serving cell and related neighboring cells (intra-frequency or inter-frequency) as appropriate.

[0054] In this embodiment, an exit condition for target measurement using LP-WUR can be configured. When the exit condition is determined to be met, the main receiver is woken up, ensuring a certain degree of timeliness and accuracy in the wake-up action. The determination of whether the exit condition is met can be based on a comparison between a first measurement value obtained through LP-WUR and a set relevant threshold. For example, if the first measurement value is less than a set relevant threshold, it can be determined that the exit condition is met.

[0055] The technical solution provided in this application embodiment allows the terminal to perform X target measurements on a low-power measurement signal within a time window of I-DRX length using LP-WUR, obtaining a first measurement value. If the first measurement value satisfies the exit condition for using LP-WUR for target measurement, the terminal wakes up the main receiver and performs target measurement through the main receiver. This enables measurement via LP-WUR, saving measurement power consumption.

[0056] In this application embodiment, exit conditions for target measurement using LP-WUR can be configured. For exit behavior, the timing of exit not only affects the energy saving gain, but may also cause the main receiver to wake up too late, resulting in the main receiver being unable to detect paging or perform measurement in time.

[0057] The measurement delay of a low-power wake-up receiver depends on the period of the low-power measurement signal. For example, the period of an LP-SS signal is significantly larger than that of an SSB signal, posing greater challenges to measurement accuracy and delay. Therefore, in an optional implementation of this application, the measurement delay, measurement accuracy, and exit conditions of the low-power wake-up receiver are comprehensively considered to ensure good energy-saving gain and timely and accurate master receiver wake-up. In this optional implementation, the exit conditions include the first measurement value satisfying a first set of threshold values ​​or the first measurement value satisfying a second set of threshold values. The first set of threshold values ​​includes at least one first threshold value, and the second set of threshold values ​​includes at least one second threshold value. The values ​​of the first threshold value and the second threshold value are different. In this optional implementation, different threshold values ​​correspond to different accuracies while ensuring timeliness; different exit conditions reduce the impact on timeliness while ensuring accuracy.

[0058] Regarding the terminal's exit from LP-WUR for target measurement, the timing of this exit not only affects energy-saving gain but may also lead to delayed wake-up of the main receiver, preventing it from performing neighbor cell measurements in a timely manner. This, in turn, impacts cell reselection and terminal mobility performance. Therefore, in the aforementioned implementation, the measurement delay of the low-power wake-up receiver and the startup delay of the main receiver should be considered for the low-power wake-up receiver's exit and wake-up behavior. The measurement delay of the low-power wake-up receiver depends on the period of the low-power measurement signal, i.e., the number of samples available for measurement within a certain time window. A higher number of samples results in higher measurement accuracy but also a longer measurement delay. When a low-power wake-up receiver performs serving cell measurements based on a low-power measurement signal (e.g., LP-SS), the typical period of the LP-SS signal (320ms) is significantly longer than the typical period of the SSB signal used by the main receiver (20ms). Therefore, in the above-mentioned optional implementation methods, the measurement delay, measurement accuracy, and exit conditions of the low-power wake-up receiver are comprehensively considered to ensure good energy-saving gain and timely and accurate main receiver wake-up. Regarding timeliness and accuracy, the terminal's paging delay can generally be considered as the time of one I-DRX. Timeliness can be reflected in the relationship between the time required for the low-power wake-up receiver to collect a certain number of measurement samples x and the I-DRX duration, such as whether it is greater than one I-DRX duration. Accuracy, as mentioned above, is reflected in the measurement accuracy achievable using this x sample.

[0059] Optionally, the second threshold value is the difference between the first threshold value and a predetermined offset value (offset or margin).

[0060] Optionally, the predetermined offset value is determined by at least one of the following:

[0061] 1) The difference between the measurement accuracy obtained by measuring the low-power measurement signal X1 times and the measurement accuracy obtained by measuring the low-power measurement signal X2 times, wherein X1 is an integer greater than or equal to the first threshold, and X2 is an integer less than the first threshold;

[0062] It should be noted that X1 is limited to an integer greater than or equal to the first threshold, and X2 is an integer less than the first threshold. However, in practical applications, X1 may not be an integer greater than or equal to the first threshold, and X2 may not be an integer less than the first threshold.

[0063] 2) Configuration of network-side devices; for example, the predetermined offset value can be configured by the system and sent to the terminal together with the first set of threshold values ​​and the second set of threshold values.

[0064] 3) Fixed value agreed upon in the agreement.

[0065] In one optional implementation, the terminal determines whether the first measurement value meets the exit condition according to the first set of threshold values ​​if at least one of the following conditions is met:

[0066] 1) The number of measurements of the low-power measurement signal is greater than or equal to the first threshold;

[0067] 2) The length of the I-DRX is greater than or equal to the second threshold.

[0068] In one optional implementation, the terminal determines whether the first measurement value meets the exit condition according to the second set of threshold values ​​if at least one of the following conditions is met:

[0069] 1) The number of measurements of the low-power measurement signal is less than the first threshold;

[0070] 2) The length of the I-DRX is less than the second threshold.

[0071] For example, in the idle / inactive state, the terminal uses a low-power wake-up receiver to perform RRM measurements, collects x samples, and then reports the measurement results.

[0072] The number of samples x collected is determined by the I-DRX value and the LP-SS period, such as x = I-DRX length / LP-SS period; the first threshold value or the second threshold value is used to determine the exit decision based on the x value and the first threshold value.

[0073] The first threshold can be determined by the number of samples y required to achieve a certain level of accuracy A.

[0074] For example, when x>=1 to the first threshold (y), the first threshold value is used as the condition for exiting. That is, by comparing the first measurement value with the first threshold value, it is determined when the LP-WUR will wake up the main receiver to perform RRM measurement.

[0075] When x < the first threshold (y), the second threshold value is used as the condition for exiting. That is, by comparing the first measurement value with the second threshold value, it is determined that the LP-WUR wakes up the master receiver to perform RRM measurement.

[0076] The predetermined offset between the first threshold and the second threshold can be determined by the difference between the accuracy B and accuracy A achieved by x samples.

[0077] For example, in the idle / inactive state, the terminal uses a low-power wake-up receiver to perform RRM measurements, collecting x samples before reporting the measurement results. The number of samples x is determined by the I-DRX value and the LP-SS period, such as x = I-DRX length / LP-SS period.

[0078] The terminal can determine whether to use the first threshold or the second threshold when exiting based on the length of the I-DRX and the second threshold. The second threshold can be determined by the duration L of the number of samples y required to achieve a certain accuracy A.

[0079] When I-DRX>=2 threshold (L), the terminal uses the first threshold value as the condition for exiting, that is, by comparing the first measurement value with the first threshold value, it determines when LP-WUR will wake up the main receiver to perform RRM measurement.

[0080] When I-DRX < the second threshold (L), the terminal uses the second threshold value as the condition for exiting. That is, by comparing the first measurement value with the second threshold value, it determines when the LP-WUR will wake up the main receiver to perform RRM measurement.

[0081] Optionally, the offset between the first threshold and the second threshold can be determined by the difference between the precision B and precision A achieved by x samples.

[0082] In an optional implementation of this application embodiment, after S412, the method may further include: the terminal determining, based on a third measurement value obtained by target measurement through the main receiver, that the entry conditions for entering target measurement using LP-WUR are met.

[0083] In the above-mentioned optional implementation methods, by setting entry conditions, the target measurement is performed using LP-WUR when the entry conditions are met, thereby saving energy. For example, whether the entry conditions are met can be determined by comparing the measurement results of the main receiver with the set relevant thresholds. When the entry conditions are met, the low-power wake-up receiver is activated to perform target measurement, generally the RRM measurement of the serving cell, thereby saving energy.

[0084] In one optional implementation, the entry condition includes the third measurement value satisfying a third set of threshold values ​​or the third measurement value satisfying a fourth set of threshold values, wherein the third set of threshold values ​​includes at least one third threshold value, the fourth set of threshold values ​​includes at least one fourth threshold value, and the values ​​of the third threshold value and the fourth threshold value are different.

[0085] Optionally, the third threshold value can be configured by the network-side device.

[0086] Optionally, the fourth threshold is more stringent than the third threshold, meaning that it is more difficult for the terminal to meet the fourth threshold.

[0087] In an optional implementation, the terminal determines whether the third measurement value meets the entry condition according to the third set of threshold values ​​if the ratio of the I-DRX length to the period of the low-power measurement signal is greater than or equal to the third threshold. That is, if the ratio of the I-DRX length to the period of the low-power measurement signal is greater than or equal to the third threshold, the terminal can compare the measurement result from the main receiver with the set third threshold value to determine whether to enter the measurement process via LP-WUR.

[0088] In an optional implementation, the terminal can determine whether the third measurement value meets the entry condition according to the fourth set of threshold values ​​if the ratio of the I-DRX length to the period of the low-power measurement signal is less than the third threshold. That is, if the ratio of the I-DRX length to the period of the low-power measurement signal is less than the third threshold, the terminal can compare the measurement result from the main receiver with the set fourth threshold value to determine whether to enter the measurement process via LP-WUR.

[0089] Optionally, the third threshold can be determined based on the number of samples y required to achieve a certain level of accuracy A.

[0090] The terminal receives paging once within each time window of the I-DRX length. A certain number of samples (e.g., x) can ensure the accuracy of measurement. Therefore, in the above implementation, if the ratio of the I-DRX length to the period of the low-power measurement signal >= x, a threshold, such as the third threshold value, can be used; while if the ratio of the I-DRX length to the period of the low-power measurement signal in bits < y, at this time, if still measuring x low-power measurement signals, the time for measuring x low-power measurement signals will be greater than the I-DRX, which has a negative impact on the delay. Therefore, the fourth threshold value (more stringent than the third threshold) is used to control the probability of entering the target measurement using the LP-WUR to avoid excessive delay.

[0091] For example, in the idle / inactive state, when the entry condition is satisfied, the terminal uses the low-power wake-up receiver for RRM measurement.

[0092] Among them, the third threshold can be determined by the number of samples x collected. Generally, the third threshold is equal to x.

[0093] The number of samples x collected is determined by the number of samples y required to achieve a certain accuracy A. Generally, x = y.

[0094] Then when the I-DRX length / LP-SS period is greater than / greater than or equal to the third threshold, the entry condition uses the third threshold value; when the I-DRX length / LP-SS period is less than the third threshold, the entry condition uses the fourth threshold value.

[0095] When the terminal uses the low-power wake-up receiver for target measurement, when judging the exit condition or entry condition for exiting or entering the use of the low-power wake-up receiver for target measurement, in the embodiments of the present application, the measurement delay, measurement accuracy, entry condition or exit condition of the low-power receiver are comprehensively considered to ensure good energy-saving gain and timely and accurate wake-up of the main receiver. On the premise of ensuring timeliness, different thresholds are set corresponding to different accuracies; on the premise of ensuring accuracy, different entry conditions or exit conditions are set to reduce the impact on timeliness.

[0096] FIG. 5 shows another schematic flowchart of the measurement method in the embodiments of the present application. This method 500 can be executed by the terminal. In other words, the method can be executed by software or hardware installed on the terminal. As shown in FIG. 5, the method may include the following steps.

[0097] S510, the terminal performs target measurement through the main receiver to obtain a third measurement value.

[0098] Among them, the target measurement is the same as the target measurement in method 400. For details, please refer to the relevant description in method 400.

[0099] In this embodiment, the terminal can periodically perform target measurements via the main receiver while in an idle / inactive state to obtain a third measurement value. For example, the terminal can periodically perform RRM measurements on the SSB signal via the main receiver while in an idle / inactive state.

[0100] The third measurement value can be a single measurement result or an average of multiple measurement results.

[0101] S512, if the third measurement value satisfies the entry condition for entering the target measurement using LP-WUR, the terminal switches to performing the target measurement via LP-WUR.

[0102] In the technical solution provided in the embodiments of this application, when the third measurement value obtained by the terminal through the main receiver meets the entry condition for using LP-WUR to perform target measurement, the terminal switches to LP-WUR and uses LP-WUR to perform target measurement, thereby reducing the power consumption of the terminal.

[0103] In one optional implementation, the entry condition includes the third measurement value satisfying a third set of threshold values ​​or the third measurement value satisfying a fourth set of threshold values, wherein the third set of threshold values ​​includes at least one third threshold value, the fourth set of threshold values ​​includes at least one fourth threshold value, and the values ​​of the third threshold value and the fourth threshold value are different.

[0104] Optionally, the third threshold value can be configured by the network-side device.

[0105] Optionally, the fourth threshold is more stringent than the third threshold, meaning that it is more difficult for the terminal to meet the fourth threshold.

[0106] In an optional implementation, the terminal determines whether the third measurement value meets the entry condition according to the third set of threshold values ​​if the ratio of the I-DRX length to the period of the low-power measurement signal is greater than or equal to the third threshold. That is, if the ratio of the I-DRX length to the period of the low-power measurement signal is greater than or equal to the third threshold, the terminal can compare the measurement result from the main receiver with the set third threshold value to determine whether to enter the measurement process via LP-WUR.

[0107] In an optional implementation, when the following conditions are met, the terminal can determine whether the third measurement value meets the entry condition according to the fourth set of threshold values: the ratio of the I-DRX length to the period of the low-power measurement signal is less than the third threshold. That is, when the ratio of the I-DRX length to the period of the low-power measurement signal is less than the third threshold, the terminal can compare the measurement result of the primary receiver with the set fourth threshold value to determine whether to enter the measurement through the LP-WUR.

[0108] Optionally, the third threshold can be determined according to the number of samples y required to achieve a certain accuracy A. <000C022>

[0109] The terminal receives a paging once within each time window of the I-DRX length, and a certain number of samples (for example, x samples) can ensure the measurement accuracy. Therefore, in the above implementation, if the ratio of the I-DRX length to the period of the low-power measurement signal >= x, a threshold, such as the third threshold value, can be used; if the ratio of the I-DRX length to the period of the low-power measurement signal in bits < y, and if x low-power measurement signals are still measured at this time, the time for measuring x low-power measurement signals will be greater than the I-DRX, which has a negative impact on the delay. Therefore, the fourth threshold value (more stringent than the third threshold) is used to control the probability of entering the target measurement using the LP-WUR to avoid excessive delay.

[0110] For example, in the idle / inactive state, when the entry condition is met, the terminal uses the low-power wake-up receiver to perform RRM measurement.

[0111] Among them, the third threshold can be determined by the number of samples x collected. Generally, the third threshold is equal to x.

[0112] The number of samples x collected is determined by the number of samples y required to achieve a certain accuracy A. Generally, x = y.

[0113] [[ID=ip]]When the I-DRX length / LP-SS period is greater than / greater than or equal to the third threshold, the third threshold value is used for the entry condition; when the I-DRX length / LP-SS period is less than the third threshold, the fourth threshold value is used for the entry condition.

[0114] In an optional implementation of the embodiment of the present application, the terminal can perform target measurement through the LP-WUR of the terminal according to the description in Method 400, and then, based on the method described in Method 400, determine whether to exit the target measurement using the LP-WUR.
