Detailed Description

It should be understood that the term "and/or" as used herein is merely one relationship describing the association of the associated objects, meaning that there may be three relationships, e.g., a and/or B, may represent: a exists alone, A and B exist together, and B exists alone. "/" indicates a relationship of "or".

To ensure normal transmission of data, the terminal device typically periodically performs RLM/BFD, where RLM is used to monitor radio link quality to determine whether the terminal device can properly receive signals sent by the network device with a sufficiently high probability. BFD is used to monitor the beam communication quality and to determine whether the terminal device is able to correctly receive signals transmitted by the network device using a particular beam with a sufficiently high probability. Typically, the network device will use multiple beams to communicate with the terminal device, and thus it can be understood that the wireless link corresponds to multiple beams. In general, if at least one beam in the radio link is normal, the radio link is considered normal, and if all beams in the radio link are abnormal, the radio link is considered abnormal.

In the new radio, NR, the basic procedure for RLM is as follows:

1. the terminal device receives the RS.

The RS for RLM is configured by a radio link monitoring configuration (radio link monitoring configuration) parameter in a downlink dedicated bandwidth part (BWP-downlink dedicated), configured only in a primary secondary cell (PSCell) and a primary cell (PCell), where PSCell and PCell are collectively referred to as a SpCell.

Each RS may be an SSB, which is composed of three parts, i.e., a primary synchronization signal (primary synchronization signals, PSS), a secondary synchronization signal (secondary synchronization signals, SSS), and a PBCH, or may be a channel state information reference signal (channal state information reference signal, CSI-RS).

Note that radio link monitoring configuration (radioplinkmotoingconfig) is used to configure both the resources of RLM and BFD. Specifically, the maximum configuration N in radio Link MonitoringConfig _LR-RLM A plurality of RSs, up to N _RLM One for RLM and a maximum of 2 for BFD. The RS used by both RLM and BFD may be the same. N (N) _LR-RLM And N _RLM Has a relationship with the maximum number of SSBs. The RS of BFD uses q in the standard ₀ To represent.

2. For each RS, the terminal device calculates a radio link quality (radio link quality).

The metric (metric) of the quality of the radio link calculated by the terminal device may be RSRP, RSRQ or signal-to-noise ratio (signal to noise ratio, SNR), or may be other metrics, which are not limited in this embodiment of the present application.

When the terminal device calculates the radio link quality, it is calculated according to the RS in the evaluation interval (evaluation period), and in order to achieve a better filtering effect, a plurality of sampling values (samples) in the evaluation interval are generally used, and specifically, how many sampling values are used is determined by the terminal device. If RS is SSB, the evaluation interval is T _{Evaluate_out_SSB} And T _{Evaluate_in_SSB} That is, when the terminal device determines whether to step out, it needs to use T _{Evaluate_out_SSB} The RS in such a long period is evaluated, and when the terminal device judges whether itself is synchronized, it is necessary to use T _{Evaluate_in_SSB} For such a long timeRS within a segment to evaluate; if the RS is CSI-RS, the evaluation interval is T _{Evaluate_out_CSI-RS} And T _{Evaluate_in_CSI-RS} That is, when the terminal device determines whether to step out, it needs to use T _{Evaluate_out_CSI-RS} The RS in such a long period is evaluated, and when the terminal device judges whether itself is synchronized, it is necessary to use T _{Evaluate_in_CSI-RS} RS over such a long period of time.

3. The wireless link quality calculated by each RS is matched with the corresponding threshold value Q _out Or Q _in And (5) comparing.

Wherein the threshold is based on block error rate (BLER), BLER _out =10% and BLER _out =2%, converted.

Threshold Q for SSB and CSI-RS _out 、Q _in Corresponding to different values. I.e. for one terminal device there is Q at the same time _{out_SSB} 、Q _{in_SSB} 、Q _{out_CSI-RS} And Q _{in_CSI-RS} Four parameters.

4. Based on the result of the comparison, the physical layer of the terminal device indicates out of sync (OOS) or In Sync (IS) to the radio resource control (radio resource control, RRC) layer.

If the radio link quality of all RSs is lower than Q _out The OOS is indicated; if the radio link quality of at least one RS is higher than Q _in IS indicated. The rest of the cases will not send an indication.

Typically, the terminal device will calculate the radio link quality once each time an indication may be needed. At least one indication interval T is arranged between the two indications _{Indication_interval} 。

According to the description in TS38.133, interval T is evaluated _{Evaluate_xx_yy} (where xx may be in or out and yy may be SSB or CSI-RS, which expressions are hereinafter collectively used to refer generally to) are generally greater than the indicated interval T _{Indication_interval} Much larger. The former is at least on the order of 200ms or more, and the latter is determined based on the minimum value of the RS period (typically 20ms when SSB is considered).

Evaluation interval T _{Evaluate_xx_yy} The calculation of (a) is as follows (extracted from TS38.133, where P is a coefficient related to the measurement gap):

Table 8.1.2.2-1 evaluation section T of Frequency Range (FR) 1 _{Evaluate_out_SSB} And T _{Evaluate_in_SSB}

Table 8.1.2.2-2 evaluation interval T of FR2 _{Evaluate_out_SSB} and T _{Evaluate_in_SSB}

Table 8.1.3.2-1 evaluation interval T of FR1 _{Evaluate_out_CSI-RS} and T _{Evaluate_in_CSI-RS}

Table 8.1.3.2-2 evaluation interval T of FR2 _{Evaluate_out_CSI-RS} and T _{Evaluate_in_CSI-RS}

Indication interval T _{Indication_interval} The calculation method of (2) is as follows:

t when C-DRX is not configured for use _{Indication_interval} ＝(10ms,T _RLM-RS,M )；

T when C-DRX is configured for use and DRX cycle length is less than or equal to 320ms _{Indication_interval} ＝Max(10ms,1.5*DRX_cycle_length,1.5*T _RLM-RS,M )；

When C-DRX is configured for use and the C-DRX cycle length is greater than 320ms, T _{Indication_interval} ＝DRX_cycle_length；

Wherein T is _RLM,M Is the minimum period of the reference signal for RLM measurement, drx_cycle_length is the C-DRX cycle length used by the terminal device.

In NR, the basic flow of BFD is substantially similar to RLM, and is described in detail as follows:

1. the terminal device receives the RS.

The characteristics of RS are as described above, and will not be described here again.

2. For each RS, the terminal device calculates the radio link quality.

When the terminal device calculates the radio link quality, the RS in the evaluation interval (evaluation period) is calculated. If RS is SSB, the evaluation interval is T _{Evaluate_BFD_SSB} The method comprises the steps of carrying out a first treatment on the surface of the If the RS is CSI-RS, the evaluation interval is T _{Evaluate_BFD_CSI-RS} 。

3. The wireless link quality calculated by each RS is matched with the corresponding threshold value Q _{out_LR} And (5) comparing.

Wherein the threshold is based on BLER _out =10% conversion.

4. Based on the result of the comparison, the physical layer of the terminal device sends a beam failure instance (beam failure instance) indication to the medium access control (media access control, MAC) layer.

Specifically, if all of the RS' corresponding radio link qualities are below their corresponding thresholds Q _{out_LR} The physical layer of the terminal device sends a beam failure instance (beam failure instance) indication to the MAC layer.

Typically, the terminal device will calculate the radio link quality once each time an indication may be needed. At least one indication interval T is arranged between the two indications _{Indication_interval_BFD} 。

Evaluation interval T _{Evaluate_BFD_yy} The calculation method (where yy may be SSB or CSI-RS, hereinafter collectively referred to using this expression) is as follows (extracted from TS38.133, where P is a coefficient related to the measurement gap):

table 8.5.2.2-1 evaluation interval T of FR1 _{Evaluate_BFD_SSB}

Table 8.5.2.2-2 evaluation interval T of FR2 _{Evaluate_BFD_SSB}

Table 8.5.3.2-1 evaluation interval T of FR1 _{Evaluate_BFD_CSI-RS}

Table 8.5.3.2-2 evaluation interval T of FR2 _{Evaluate_BFD_CSI-RS}

t when C-DRX is not configured for use _{Indication_interval} ＝(2ms,T _SSB-RS,M ) Or (2 ms, T) _CSI-RS,M )；

T when C-DRX is configured for use and DRX cycle length is less than or equal to 320ms _{Indication_interval} ＝Max(1.5*DRX_cycle_length,1.5*T _SSB-RS,M ) Or Max (1.5×drx_cycle_length,1.5×t) _CSI-RS,M )；

Wherein T is _SSB-RS,M And T _CSI-RS,M Is the minimum period of SSB and CSI-RS for BFD, drx_cycle_length is the C-DRX cycle length used by the terminal device.

In the prior art, in order to reduce the power consumption of the terminal device due to performing RLM and/or BFD, the indication interval T is simply indicated _{Indication_interval} Increasing. Because the terminal device is every otherIndication interval T _{Indication_interval} Once the radio link quality is calculated, so the indication interval T is increased _{Indication_interval} The method is equivalent to reducing the number of times of calculating the wireless link quality by the terminal equipment and reducing the calculated amount of the terminal equipment. However, this method can only reduce the baseband power consumption of the terminal device to a certain extent, but cannot reduce the radio frequency power consumption thereof.

The specific analysis is as follows:

fig. 1 is a schematic diagram of the relationship between the indication interval and the evaluation interval in RLM/BFD and the reference signal. As shown in fig. 1, where each arrow represents a terminal device calculating the radio link quality once, i.e. indicating an interval T1, each shadow represents an RS.

If the prior art scheme is adopted, the indication interval T _{Indication_interval} Relaxation, e.g. increasing the indication interval T _{Indication_interval} To indicate interval T in FIG. 1 _{Indication_interval} As can be seen from fig. 2, the number of RSs that the terminal apparatus needs to receive and process is unchanged, as indicated by the indication interval T2 being 2 times the indication interval T1.

In addition, the above-mentioned prior art cannot effectively reduce the power consumption of the terminal device, considering that the power consumption of the radio frequency part (i.e., the power of the received RS) is much greater than the power consumption of the baseband part (i.e., the calculation of the radio link quality and the physical layer transmission of the indication to the MAC layer or the RRC layer) when the terminal device performs RLM/BFD.

Based on the above problems, embodiments of the present application provide a measurement method, apparatus, and storage medium, where when a terminal device executes RLM and/or BFD, an indication interval and an evaluation interval are changed at the same time, so as to effectively reduce power consumption of the terminal device.

The terminal device determines whether the parameter change condition is satisfied, wherein a specific determination manner will be described in detail below. The parameter change condition may be predefined, for example, specified in a standard, or may be configured by the network device for the terminal device, and may specifically be set according to the actual situation, which is not limited in the embodiment of the present application.

And S402, when the parameter change condition is met, the terminal equipment measures according to the second value of the indication interval and the second value of the evaluation interval.

Wherein the indication interval (T _{Indication_interval} ) The minimum interval indicated for the physical layer of the terminal device to send to the higher layers of the terminal device. The first value of the indication interval is determined based on the period of the reference signal. Evaluation interval (T) _{Evaluate_xx_yy} Or T _{Evaluate_BFD_yy} ) The time interval in which the reference signal used when the radio link quality is once calculated for the terminal device. The first value of the evaluation interval is determined from the period of the reference signal.

The higher layers of the terminal device here include a MAC layer and an RRC layer: in RLM, the higher layer is the RRC layer; in BFD, the higher layer is the MAC layer. It can be understood that the indication interval is a parameter name, the evaluation interval is a parameter name, and specific values thereof can be determined in various manners, for example, the indication interval is determined by a formula, which is the same as the prior art, wherein the corresponding formulas under different conditions are different; for another example, the network device configures the indication intervals or the evaluation intervals under different conditions in advance, and stores the indication intervals or the evaluation intervals in the form of a table or the like, and in practical application, the network device sends the table or the like to the terminal device, and the terminal device only needs to read the value corresponding to the current condition from the table according to the current condition, and the embodiment of the application is not limited. Taking the indication interval as an example, the first value of the indication interval and the second value of the indication interval are two different values indicating the indication interval, and the second value of the indication interval is not the parameter.

In the first case, the second value of the indication interval is larger than the first value of the indication interval, and the second value of the evaluation interval is smaller than the first value of the evaluation interval.

Still referring to fig. 1 or 2, because the "measurement window" formed by the evaluation interval (each bracket above represents a measurement window) is too large, when two or more positions for calculating the quality of the radio link (i.e., positions of arrows in the figure) are included in one "measurement window", one "measurement window" includes 1 or more indication intervals, and in practical application, the evaluation interval is about ten times the indication intervals, and the two intervals are very different. This has the consequence that any one RS belongs to at least one "measurement window", and it is not possible to actually reduce the number of RSs that the terminal device needs to measure. Therefore, compared with the prior art, the embodiment of the application not only increases the indication interval, but also shortens the evaluation interval, and shortens the difference between the indication interval and the evaluation interval; in addition, since the calculation of the radio link quality is performed for the RS in the evaluation interval (evaluation period), shortening the evaluation interval is equivalent to reducing the number of RSs of the terminal device when calculating the radio link quality, so that the power consumption of the terminal device can be effectively reduced.

Optionally, the parameter change condition is configured by the network device to the terminal device. Alternatively, the parameter change condition is predefined in the standard, preconfigured at the time of shipment of the terminal device. Correspondingly, the network device generates and transmits a parameter change condition to the terminal device.

According to the measurement method provided by the embodiment of the application, the terminal equipment firstly determines whether the parameter change condition is met, and when the parameter change condition is met, the measurement is carried out according to the second value of the indication interval and the second value of the evaluation interval, wherein the second value of the indication interval is larger than the first value of the indication interval, the first value of the indication interval is determined according to the period of the reference signal, the second value of the evaluation interval is smaller than the first value of the evaluation interval, and the first value of the evaluation interval is determined according to the period of the reference signal. The embodiment shortens the evaluation interval of the terminal equipment when the measurement is performed while increasing the indication interval of the terminal equipment when the measurement is performed, so that the difference between the indication interval and the evaluation interval is reduced, the RS number of the terminal equipment when the wireless link quality is calculated is reduced, and the power consumption of the terminal equipment can be effectively reduced.

In one implementation manner, the second value of the evaluation interval is smaller than the second value of the indication interval. For example, as shown in fig. 5, the second value of the indication interval is the indication interval T2, and the second value of the evaluation interval is smaller than the indication interval T2, so that "measurement windows" formed by the evaluation interval (each bracket above represents a measurement window) are not overlapped, compared with the embodiment shown in fig. 2 or fig. 3, the terminal device does not need to receive and process the RS of the dashed frame any more, and some measured RSs can be reduced, so that not only the power consumption of the baseband portion of the terminal device but also the power consumption of the radio frequency portion of the terminal device is reduced, and thus the power consumption of the terminal device is greatly reduced.

Further, the period of time for the network device to transmit the RS may also vary. In some scenarios, the network device may know the measurement interval of the terminal device, that is, the network device knows which RSs the terminal device actually receives, at this time, for RSs not received by the terminal device, the network device may choose not to transmit, according to the transmitted RSs of the changed period, referring to fig. 5, for RSs in which the dashed box, the network device does not transmit any more. Wherein the RS corresponds to the terminal equipment, and the terminal equipment is different from the RS.

In some embodiments, the first value of the indication interval is determined according to a predefined first formula and a period of the RS, and the first value of the evaluation interval is determined according to a predefined second formula and a period of the reference signal. Specifically, substituting the period of the RS into a first formula to obtain a first value of the indication interval; or substituting the period of the RS into the second formula to obtain a first value of the evaluation interval. Wherein the first formula is different from the second formula. And, the corresponding first formula or second formula is different under different configurations. It can be understood that the first formula is a formula for obtaining the indication interval in the existing standard, and the second formula is a formula for obtaining the value of the evaluation interval in the existing standard, and in different configurations, the formulas used are different, and the table described above can be specifically referred to.

In one implementation, the second value of the indication interval is determined according to a predefined third formula and the period of the RS, and the second value of the evaluation interval is determined according to a predefined fourth formula and the period of the reference signal. Specifically, substituting the period of the RS into a third formula to obtain a second value of the indication interval; substituting the period of RS into a fourth formula to obtain a second value of the evaluation interval. Wherein the third formula is different from the fourth formula. And, the corresponding second formulas under different configurations are different.

With respect to the third formula and the fourth formula, it is understood that a new formula or a new table is defined in the standard, and the new table contains the new formula. The indication interval and the evaluation interval are calculated using different formulas or tables in different configurations. To evaluate the interval T _{Evaluate_out_SSB} For example, in the existing standard, the calculation method is Max (200, ceil (10×p) ×t _SSB ) That is, the second formula for obtaining the first value of the evaluation interval is Max (200, ceil (10×p) ×t _SSB ). Further, a new formula can be defined as Max (50, ceil (2.5P) T _SSB ) When the parameter changing condition is satisfied, the new formula is used to obtain the second value of the evaluation interval, that is, the fourth formula of the second value of the evaluation interval is Max (50, ceil (2.5×p) ×t _SSB ). The formulas for the different configurations may also be tabulated as in the existing standard. Or, setting a plurality of thresholds, wherein different threshold intervals correspond to different third formulas and fourth formulas. For example, a plurality of threshold values rsrp= -110dBm and rsrp= -100dBm are set, when RSRP is lower than-110 dBm, when RSRP is between-110 dBm and-100 dBm, and when RSRP is above-100 dBm, the third formula and the fourth formula corresponding to each of the three cases are different even if the same configuration is adopted.

Therefore, in some embodiments, before the terminal device performs measurement according to the second value of the indication interval and the second value of the evaluation interval, the measurement method may further include: acquiring signal parameters, wherein the signal parameters comprise RSRP and/or RSRQ; determining whether the signal parameter is greater than a preset threshold, wherein the preset threshold is one of a plurality of thresholds; and determining a third formula and/or a fourth formula according to a preset threshold value.

In another implementation, the second value indicative of the interval is determined according to a predefined first formula, a predefined first scaling factor and a period of the reference signal, and the second value of the evaluation interval is determined according to a predefined second formula, a predefined second scaling factor and a period of the reference signal. Specifically, a first scaling factor is introduced in a predefined first formula or a second scaling factor is introduced in a predefined second formula. For example, to evaluate interval T _{Evaluate_out_SSB} For example, in the existing standard, the calculation method is Max (200, ceil (10×p) ×t _SSB ). A second scaling factor S may be introduced to change the formula to Max (200, ceil (10 x p) x T _SSB ) S. When the parameter changing condition is satisfied, the value of the second scaling factor S is 0.25, and when the parameter changing condition is not satisfied, the value of the second scaling factor S is 1. Further, when the "parameter changing condition" is divided into several steps, the second scaling factor S may be more than two. For example, setting a plurality of thresholds rsrp= -110dBm and rsrp= -100dBm, the second scaling factor s=1 when RSRP is lower than-110 dBm; RSRP is between-110 dBm and-100 dBm with a second scaling factor s=0.5; the second scaling factor s=0.25 when RSRP is above-100 dBm.

Therefore, in some embodiments, before the terminal device performs measurement according to the second value of the indication interval and the second value of the evaluation interval, the measurement method may further include: acquiring signal parameters, wherein the signal parameters comprise RSRP and/or RSRQ; determining whether the signal parameter is greater than a preset threshold, wherein the preset threshold is one of a plurality of thresholds; and determining the first scaling factor and/or the second scaling factor according to a preset threshold.

On the basis of the above, wherein the parameter changing condition may include at least one of:

1. the RSRP/RSRQ is greater than a preset threshold. The condition reflects that the channel condition is good, and when the channel condition is good enough, sufficient measurement accuracy can be achieved even if the measurement time is short, so that the evaluation interval can be reduced somewhat.

As for the acquisition of RSRP/RSRQ, this can be achieved by means of real-time measurement:

the RSRP/RSRQ can be obtained by real-time measurement. However, under extreme conditions, for example, when the signal strength fluctuates greatly, the data obtained by real-time measurement is transient, at this time, the RSRP/RSRQ is obtained by real-time measurement based on the time t, and the parameter change condition is determined to be satisfied, and at the time t+1, the terminal device is ready to perform measurement according to the second value of the indication interval and the second value of the evaluation interval, but the RSRP/RSRQ may be greatly changed in this time compared with the time t, and the second value of the indication interval and the second value of the evaluation interval are not applicable.

Based on the above considerations, a priori information may be added in the acquisition of the RSRP/RSRQ, as described below.

At this time, S401, determining whether the parameter change condition is satisfied may include: if the RSRP or the RSRQ is larger than a preset threshold value, determining that a parameter change condition is met; or if the RSRP or RSRQ is less than or equal to the preset threshold, determining that the parameter change condition is not satisfied.

2. The speed of the terminal equipment is smaller than a preset speed, or the variation amplitude of the RSRP/RSRQ is smaller than a preset range. Since the channel fluctuation is usually smaller when the speed of the terminal device is lower, the amplitude of the instantaneous channel change is smaller, i.e. the amplitude of the change of RSRP/RSRQ is smaller. At this time, the length of the evaluation interval does not greatly affect the evaluation result, so that the evaluation interval can be reduced.

In practical applications, the speed of the terminal device may be obtained in a variety of ways. For example, in one way, the data of 8:00-10:00 user sitting on high-speed rail is obtained in combination with intelligent life, and the speed of the terminal equipment is high and is about the high-speed rail; in another mode, an acceleration sensor built in the terminal device, such as a priori information, classifies a traffic mode: and determining whether the user carrying the terminal equipment sits on the car or walks according to the acceleration sensor, and correspondingly judging whether the indication interval value and the evaluation interval value need to be changed at the moment.

Illustratively, a user communicates with a base station using a cell phone. The speed is slower when the user walks, the change of the channel condition around the mobile phone is slower, and at this time, the mobile phone may perform RLM/BFD in a manner specified in the existing standard, that is, "RLM/BFD is performed according to the first value of the indication interval and the first value of the evaluation interval" in the embodiment of the present application. When the user takes a car at a higher speed, the change of the channel condition around the mobile phone is faster, and at this time, the mobile phone may perform RLM/BFD in a mode of lower power consumption, that is, "RLM/BFD is performed according to the second value of the indication interval and the second value of the evaluation interval" in the embodiment of the present application. The second value indicative of the interval may be determined according to a predefined third formula and the second value of the evaluation interval may be determined according to a predefined fourth formula; alternatively, the second value indicative of the interval may be determined according to a predefined first formula and a predefined first scaling factor, and the second value of the evaluation interval may be determined according to a predefined second formula and a predefined second scaling factor; alternatively, the second value of the indication interval and the second value of the evaluation interval may be determined according to a period after the reference signal is increased.

Further, in the preset time period, when the speed of the terminal device is smaller than the preset speed, it is determined that the parameter change condition is satisfied.

At this time, S401, determining whether the parameter change condition is satisfied may include: if the variation amplitude of the RSRP or the RSRQ is smaller than the preset range, determining that the parameter change condition is met; or if the variation amplitude of the RSRP or the RSRQ is greater than or equal to the preset range, determining that the parameter change condition is not satisfied.

Or, S401, determining whether the parameter change condition is satisfied may include: if the speed of the terminal equipment is smaller than the preset speed, determining that the parameter change condition is met; if the speed of the terminal equipment is greater than or equal to the preset speed, the parameter change condition is determined not to be met.

3. The current scene is a preset scene, such as outdoors, etc.

And (5) scene recognition. Such as underground and open squares, malls, etc. A scene model is created in advance based on the test data related to the RSRP or the RSRQ, and when the terminal equipment such as a mobile phone detects the reference signal to input the RSRP or the RSRQ, the scene model can output a current scene, and whether the parameter change condition is met or not is determined according to the current scene.

Thus, S401, determining whether the parameter change condition is satisfied may include: if the current scene is a preset scene, determining that the parameter change condition is met; or if the current scene is not the preset scene, determining that the parameter change condition is not met.

The user uses the mobile phone to communicate with the base station, and the attenuation of the signal sent by the base station to the mobile phone is larger and the channel condition is poorer because the signal is shielded by a room when the user is indoor; the shielding is less when outdoor, the attenuation from the signal sent by the base station to the mobile phone is less, and the channel condition is relatively good. When a user moves with a handset from indoor to outdoor (scene change), the handset may experience a change in RSRP from never below the threshold to above the threshold. In this case, the mobile phone may perform RLM/BFD in a manner specified in the existing standard, that is, "RLM/BFD is performed according to the first value of the indication interval and the first value of the evaluation interval" in the embodiment of the present application. The mobile phone may perform RLM/BFD outdoors in a manner with lower power consumption, i.e. "performing RLM/BFD according to the second value of the indication interval and the second value of the evaluation interval" in the embodiment of the present application. Specifically, the second value of the indication interval may be determined according to a predefined third formula, and the second value of the evaluation interval may be determined according to a predefined fourth formula; alternatively, the second value indicative of the interval may be determined according to a predefined first formula and a predefined first scaling factor, and the second value of the evaluation interval may be determined according to a predefined second formula and a predefined second scaling factor; alternatively, the second value of the indication interval and the second value of the evaluation interval may be determined according to a period after the reference signal is increased.

4. The frequency of use is less than a preset number of times.

The service condition of the terminal equipment is simply seen. For example, the user does not use the mobile phone at night when sleeping, and the mobile phone is mainly energy-saving; for example, if the user uses a lot of mobile phones in daytime, RSRP or RSRQ is detected according to the real-time situation, and when RSRP or RSRQ reaches a threshold, the indication interval and the evaluation interval are switched to the second value corresponding to the threshold.

S401, determining whether the parameter change condition is satisfied may include: if the frequency of use is smaller than the preset times, determining that the parameter change condition is met; or if the frequency of use is greater than or equal to the preset number of times, determining that the parameter change condition is not satisfied.

5. A priori information.

For a priori information, for example, the user's workday actions are regular, at fixed points in time, e.g., 8:00-10:00, collecting the time period data, and obtaining an interval according to RSRP or RSPQ, wherein 8: the 30-9:00 signal is always good, at which time the terminal device can shorten the evaluation interval and increase the indication interval during the period of 8:30-9:00.

Or determining whether the user uses the mobile phone frequently in a time interval, specifically, whether the user uses the mobile phone can be judged by judging whether the terminal equipment is in a bright screen state. If the terminal equipment is in a bright screen state, and the user is determined to use the mobile phone, the terminal equipment can shorten the evaluation interval and increase the indication interval.

The above five conditions may be arbitrarily combined.

For example, combining real-time measurements with a priori information. Specifically, the terminal device firstly measures signals to obtain RSRP/RSRQ, and then judges whether the RSRP/RSRQ is larger than a preset threshold value. If the RSRP/RSRQ is larger than the preset threshold, the terminal equipment further judges whether the current time is a time period with a better signal according to the prior information. If the current time belongs to the time period with better signal, the terminal device can shorten the evaluation interval and increase the indication interval. It can be understood that the terminal device may also determine, according to the prior information, whether the current time is a time period in which the signal is good. If the current time belongs to the time period with better signal, the terminal equipment further judges whether the RSRP/RSRQ measured in real time is larger than a preset threshold value. In addition, the terminal device may also determine whether these two conditions are satisfied at the same time. The sequence of judging the conditions in the embodiment of the application is not limited.

Or determining whether the user uses the mobile phone frequently in the time interval, specifically, whether the user uses the mobile phone can be judged by judging whether the terminal equipment is in a bright screen state. If the terminal equipment is in a bright screen state, determining that the user uses the mobile phone, measuring and obtaining the RSRP/RSRQ in real time by the terminal equipment, and then judging whether the RSRP/RSRQ is larger than a preset threshold value or not. Or the terminal equipment firstly measures and obtains the RSRP/RSRQ in real time and then judges whether the RSRP/RSRQ is larger than a preset threshold value. If the RSRP/RSRQ is larger than the preset threshold, the terminal equipment further judges whether the current time is a time period when the user frequently uses the mobile phone according to the prior information. If the current time belongs to the time period when the user frequently uses the mobile phone, the terminal equipment can shorten the evaluation interval and increase the indication interval. In addition, the terminal device may also determine whether these two conditions are satisfied at the same time. The sequence of judging the conditions in the embodiment of the application is not limited.

As a possible implementation, the parameter change conditions are different, indicating that the magnitudes of the interval updates are different; and/or the parameter change conditions are different, and the amplitudes of the evaluation period updates are different. The parameter changing condition can be further divided into several gears, and the amplitude of the terminal equipment increasing the indication interval and the amplitude of the terminal equipment decreasing the evaluation interval can be different under different gears. For example, taking RSRP as an example, rsrp= -110dBm may be taken as a threshold above which the terminal device measures based on the second value of the indication interval and the second value of the evaluation interval; when the threshold value is lower, the terminal device performs measurement based on the first value of the indication interval and the first value of the evaluation interval.

Alternatively, two thresholds rsrp= -110dBm and rsrp= -100dBm are set. The first scene is lower than-110 dBm, and the terminal equipment measures based on the first value of the indication interval and the first value of the evaluation interval; scene two, between-110 dBm and-100 dBm, the terminal equipment measures based on the second value of the indication interval and the second value of the evaluation interval; and the third scene is more than-100 dBm, the terminal equipment measures based on the second value of the indication interval and the second value of the evaluation interval, the second value of the indication interval corresponding to the threshold range is larger than the second value of the indication interval corresponding to the threshold range in the second scene, and the second value of the evaluation interval corresponding to the threshold range is smaller than the second value of the evaluation interval corresponding to the threshold range in the second scene.

In the second case, the second value of the indication interval is greater than the first value of the indication interval, and the second value of the evaluation interval is greater than the first value of the evaluation interval.

For the first value of the indication interval and the first value of the evaluation interval, and the description of the first formula, the second formula, the parameter changing condition, etc., reference may be made to the first case, and details thereof will not be repeated here.

The second case differs from the first case in that: in the second case, the second value of the indication interval and the second value of the evaluation interval are determined according to the period of the RS after the increase.

In the existing standard, the indication interval and the evaluation interval are both calculated from the period of the RS. When the period of the RS increases, the indication interval and the evaluation interval increase in proportion. Thus, in this implementation, the ratio of the second value of the indication interval to the first value of the indication interval is equal to the proportion of the periodic increase of the RS; and the ratio of the second value of the evaluation interval to the first value of the evaluation interval is equal to the period increasing proportion of the RS.

Referring to fig. 1 and 6, fig. 6 shows a schematic diagram after a period of increasing RS shown in fig. 1. As shown in fig. 6, after the period of the RS to be measured is increased, the number of RSs actually measured by the terminal device becomes smaller, so that the power consumption of the terminal device can be saved. In addition, since the number of RSs used for evaluation is unchanged in each evaluation period, the measurement accuracy of the terminal device is not affected.

It should be noted that, increasing the period of the RS is a spontaneous behavior of the terminal device when it is determined that the parameter change condition is satisfied, and no indication of the network device or reconfiguration of the RS is required, so signaling overhead can be reduced.

Wherein increasing the period of the RS may be achieved in a number of ways, as exemplified below.

In one implementation, the RS is unchanged, but the terminal device receives the RS with a larger period, that is, the period in which the network device sends the RS is not changed, and the terminal device may increase the period in which the RS is received according to the condition, and part of the RS is not received and processed by the terminal device, as shown in fig. 5. For example, the terminal device receives one RS every N periods of the RS. Further, the period of time for the network device to transmit the RS may also vary. In some scenarios, the network device may know the measurement interval of the terminal device, that is, the network device knows which RSs the terminal device actually receives, at this time, for RSs not received by the terminal device, the network device may choose not to transmit, according to the transmitted RSs of the changed period, referring to fig. 5, for RSs in which the dashed box, the network device does not transmit any more. Wherein the RS corresponds to the terminal equipment, and the terminal equipment is different from the RS.

In another implementation, the network device configures multiple groups of RSs for the terminal device, where the terminal device uses different RSs under different conditions. For example, when the terminal device determines that the parameter change condition is not satisfied, RS1 is used; when the terminal device determines that the parameter change condition is satisfied, RS2 is used, wherein the period of RS2 is larger than the period of RS 1. At this time, the second value of the indication interval and the second value of the evaluation interval are determined according to the period of RS2. In this scheme, since the network device does not know whether the terminal device uses RS1 or RS2, the network device should transmit RS1 and RS2 at the same time.

According to the measurement method provided by the embodiment of the application, the terminal equipment firstly determines whether the parameter change condition is met, and when the parameter change condition is met, the measurement is carried out according to the second value of the indication interval and the second value of the evaluation interval, wherein the second value of the indication interval is larger than the first value of the indication interval, the first value of the indication interval is determined according to the period of the reference signal, the second value of the evaluation interval is larger than the first value of the evaluation interval, and the first value of the evaluation interval is determined according to the period of the reference signal. The embodiment increases the indication interval of the terminal equipment when the measurement is performed and also increases the evaluation interval of the terminal equipment when the measurement is performed, so that the number of RS actually measured by the terminal equipment is reduced, and the power consumption of the terminal equipment can be effectively reduced.

On the basis of the above embodiment, as shown in fig. 7, the measurement method may include:

s701, the terminal equipment sends first information to the network equipment.

Wherein the first information is used to instruct the terminal device to support the parameter change mode.

In this embodiment, the terminal device reports its capability of supporting the parameter change mode to the network device through the first information. The parameter change mode, which may be called as a power saving mode, refers to updating the value of the indication interval and the value of the evaluation interval when the parameter change condition is satisfied, so as to achieve the purpose of reducing the power consumption of the terminal device.

Or alternatively, for terminal devices supporting the parameter change mode, the device identification thereof is default, that is, terminal devices with some default device identification, which support the parameter change mode. Alternatively, the terminal device indicates that it supports the parameter change mode through the reserved field.

Correspondingly, the network device receives the first information.

S702, the network equipment configures second information for the terminal equipment based on the first information.

The second information is used for indicating information used by the terminal device when obtaining the second value of the indication interval and/or the second value of the evaluation interval.

Alternatively, the second information may be a specific value, such as a second value. Alternatively, the second information may be a formula such as the first formula, the second formula, the third formula, the fourth formula, and the like mentioned in the above embodiments. Alternatively, the second information may be a table, which contains formulas. Alternatively, the second information may be a formula index, or the like.

S703, the network device sends the second information to the terminal device.

Correspondingly, the terminal device receives the second information.

S704, the terminal device determines whether the parameter change condition is satisfied.

For how the terminal device determines whether the parameter change condition is satisfied, reference is made to the above description, and a detailed description is omitted here.

When the terminal device determines that the parameter change condition is satisfied, S705 is executed; otherwise, the terminal device performs S706.

And S705, the terminal equipment measures according to the second value of the indication interval and the second value of the evaluation interval.

This step is similar to S402 and will not be described here again.

S706, the terminal equipment measures according to the first value of the indication interval and the first value of the evaluation interval.

In some embodiments, whether the terminal device supports the parameter change mode may be set through an interface button. For example, as shown in fig. 8, when o of the interface button is located on the left side, the default parameter change mode is off; when the user slides o to the right of the interface button, the parameter change mode is turned on by default. In this way, the user can determine whether to turn on the parameter change mode according to personal needs. For example, when the user does not use the mobile phone for a long time, the on parameter change mode may be selected; alternatively, when the user is riding a high-speed rail, a shutdown parameter change mode may be selected, and so on.

Alternatively, in some embodiments, the terminal device automatically turns on/off the parameter change mode based on the current behavior of the user.

Alternatively, corresponding to the above-described embodiment, when the parameter change condition is not satisfied, the parameter change mode is turned off.

After switching off the parameter change mode, the terminal device performs a measurement according to the first value of the indication interval and the first value of the evaluation interval.
