Description

Measuring method, device, terminal and storage medium

Technical Field

The present application relates to the field of wireless communications, and in particular, to a measurement method, an apparatus, a terminal, and a storage medium.

Background

In the related art, a terminal performs mobility behaviors such as cell reselection, handover, and the like based on measurement of a Synchronization Signal Block (SSB) or a channel state information-reference signal (CSI-RS). In the measurement, the behavior, the time delay and the accuracy of the terminal are specified, and taking SSB as an example, the measurement of the SSB of a certain frequency point by the terminal needs to meet a certain measurement time delay index.

In a Carrier Aggregation (CA) scenario, the measurement time requirement for a terminal on multiple carriers is related to the number of carriers, and the greater the number of carriers, the longer the measurement time.

In a high-speed rail scene, high-speed movement is very sensitive to measurement delay, so that a new measurement mode needs to be introduced according to the requirement of high-speed movement.

Detailed Description

The present application will be described in further detail with reference to the following drawings and examples.

In a CA scenario, the measurement time requirement of the terminal for the plurality of secondary carriers is related to the number of the secondary carriers, and the more the number of the secondary carriers is, the longer the measurement time is.

In the related art, the terminal measurement behavior in the CA scenario is simply based on the measurement duration of a single Carrier and is simply multiplied by the number of Secondary carriers (SCCs), and the greater the number of Secondary carriers, the longer the measurement time. However, in a High Speed Train (HST) scenario (where the moving Speed meets a certain threshold, such as 350km/h or 500km/h, etc.), since High-Speed movement is very sensitive to measurement delay, this approach cannot meet the mobility requirement of the High-Speed scenario. Therefore, a new measurement method needs to be introduced to improve the terminal measurement performance in response to the requirement of high-speed mobility.

Based on this, in various embodiments of the present application, the measurement behavior of the terminal is specified by using the time domain position relationship of the reference signal between different carriers, and the reference signal configuration of the secondary carrier (for example, whether the measurement is measurement requiring a measurement interval and measurement not requiring a measurement interval).

The embodiment of the application provides a measurement method, which is applied to a terminal, and as shown in fig. 1, the method includes:

Here, in practical applications, the twentieth value refers to a total number of carriers, where the total number of carriers may include a sum of at least two of a number of carriers that completely overlap with time domains of the CSI-RS and the PRS, a number of carriers that completely do not overlap with time domains of the CSI-RS and the PRS, and a number of carriers that partially overlap with time domains of the CSI-RS and the PRS.

carriers based on SSB measurements;

a carrier based on CSI-RS measurements;

a carrier based on PRS measurements.

The seventeenth threshold and the eighteenth threshold may be set as needed.

The network side may indicate the seventeenth threshold and/or the eighteenth threshold to the terminal through signaling, such as RRC signaling, MAC CE, DCI, or the like, or may pre-define the seventeenth threshold and/or the eighteenth threshold, so as to pre-set the seventeenth threshold and/or the eighteenth threshold in the terminal.

The carrier waves of which the time domains of the CSI-RS and the PRS are not overlapped refer to the carrier waves of which the time domains of the CSI-RS and the PRS are not overlapped; correspondingly, the time domain interval of the CSI-RS and the PRS refers to the time domain interval between the CSI-RS and the PRS; the complete time domain overlapping of the CSI-RS and the PRS refers to complete time domain overlapping carriers between the CSI-RS and the PRS; the carrier with the partially overlapped time domains of the CSI-RS and the PRS refers to a carrier with the partially overlapped time domains between the CSI-RS and the PRS.

Here, it is considered that the same network may serve multiple scenarios at the same time, and different scenarios may consider different factors, so that the first factor has different values, for example, for enhanced mobile bandwidth (eMBB) service, ultra-high reliable low latency communication (URLLC) service, and large-scale machine type communication (mtc) service, different values of the first factor are adopted; for example, for a high-speed rail (i.e., high-speed) scene and a non-high-speed rail (i.e., non-high-speed) scene, different values of the first factor are adopted.

In practical application, when measurement is performed based on the first factor, the measurement behavior of the terminal may be defined as:

the measurement of the target multiple carriers needs to be completed within a certain time length, which is related to the measurement time length of the single carrier, the first factor, and other factors.

In practical application, the terminal needs to determine the first factor and then perform measurement based on the first factor.

Based on this, in an embodiment, as shown in fig. 1, the method may further include:

step 100: the first factor is determined.

The terminal may determine the first factor according to time domain location information of sounding reference signals of different carriers. That is, the terminal determines the first factor according to time domain position information of a reference signal.

The terminal may also determine the first factor according to network information, for example, the network side indicates the first factor through signaling, such as RRC signaling, MAC CE, or DCI.

Here, when the terminal determines the first factor according to the time domain location information of the reference signals of different carriers, the terminal may determine the first factor in the above manner.

Specifically, in one embodiment, the first factor is determined to be a first value when non-overlapping carriers (i.e., carriers that do not overlap in time domain) exist among the carriers. Here, in practical application, when non-overlapping carriers exist in the carriers, the value of the first factor may be a first value, and the first value may be a difference included in the first factor. Exemplarily, assuming that there are 9 carriers, there are non-overlapping carriers in the carriers, and the number of the carriers is 4, when the value of the first factor is 9-4=5 in a manner of a difference and/or a sum of the numbers included in the first factor.

In practical application, when the value of the first factor is directly determined by using the above method, although the measurement performance may be improved (i.e., the measurement delay is reduced), the complexity of the terminal measurement may also be increased. Therefore, in order to take the measurement performance and the complexity of the terminal implementation into consideration, the value of the first factor may not be the sum of the difference and/or the number included in the first factor.

Based on this, in an embodiment, when there is a carrier with a time domain interval greater than or equal to a sixth threshold among the carriers, the first factor is determined to be a second value.

In this case, for the second value, it may be understood as relaxation, rather than using the sum of the above-mentioned differences and/or numbers included in the first factor in the same situation, but performing a certain amplification on the basis of the sum. Exemplarily, assuming that there are 9 carriers, the number of carriers whose time domain interval is greater than and/or equal to the first threshold is 5, and in these 5 carriers, there are carriers whose time domain interval is greater than or equal to the sixth threshold, at this time, when a difference and/or a sum of the numbers included in the first factor is used, a value of the first factor may be obtained as 9-5=4, but considering complexity of implementation of terminal measurement, that is, considering implementation capability of the terminal, complexity of implementation of the terminal is reduced, and a value of the first factor may be 5.

In actual application, the second value may be indicated by a network side (or may be understood as being notified by the network side), for example, the network side indicates the second value to the terminal through RRC signaling, MAC CE, DCI, or the like, or may be predefined, and thus is preset in the terminal, or may be determined by the terminal itself.

The sixth threshold may also be indicated by a network side, for example, the network side indicates the sixth threshold to the terminal through RRC signaling, MAC CE, DCI, or the like, that is, the terminal receives the sixth threshold, which may also be predefined and thus preset in the terminal.

In an embodiment, the first factor is determined to be a third value when there are non-overlapping carriers among the carriers and a number of non-overlapping carriers satisfies a seventh threshold.

In this case, for the third value, it can be understood as relaxation, rather than using the sum of the above-mentioned differences and/or numbers included in the first factor in the same case, but performing a certain amplification on the basis of the sum. For example, assuming that there are 9 carriers, the number of non-overlapping carriers in a carrier is 5 and is greater than 3 (i.e., a seventh threshold), at this time, when a difference and/or a sum of the numbers included in the first factor is used, it may be obtained that a value of the first factor is 9-5=4, but considering complexity of implementation of terminal measurement, that is, considering implementation capability of a terminal, complexity of implementation of the terminal is reduced, and a value of the first factor may be 5.

In practical application, the third value may be indicated by a network side, for example, the network side indicates the third value to the terminal through signaling, such as RRC signaling, MAC CE, or DCI, or may be predefined, so as to be preset in the terminal, or may be determined by the terminal itself.

The seventh threshold may also be indicated by a network side, for example, the network side indicates the seventh threshold to the terminal through RRC signaling, MAC CE, DCI, or the like, that is, the terminal receives the seventh threshold, which may also be predefined and thus preset in the terminal. The seventh threshold may be in the form of an integer or a ratio, such as the ratio of the number of non-overlapping carriers to the total number of carriers.

In an embodiment, when there are carriers with a time domain interval greater than or equal to a sixth threshold among the carriers, and the number of carriers with a time domain interval greater than or equal to the sixth threshold satisfies an eighth threshold, the first factor is determined to be a fourth value.

In this case, for the fourth value, it may be understood to be relaxed, rather than using the sum of the above-mentioned differences and/or numbers included in the first factor in the same situation, but performing a certain amplification based on the sum. Exemplarily, assuming that there are 9 carriers, the number of carriers having a time domain interval greater than and/or equal to the first threshold is 5, and among the 5 carriers, there are carriers having a time domain interval greater than or equal to the sixth threshold, the number is 3, and is greater than 2 (i.e. an eighth threshold), at this time, when a value of the first factor is 9-5=4 in a manner of a sum of differences and/or numbers included in the first factor, but considering complexity of implementation of terminal measurement, that is, considering implementation capability of the terminal, so as to reduce complexity of implementation of the terminal, the value of the first factor may be 6.

In practical application, the fourth value may be indicated by a network side, for example, the network side indicates the fourth value to the terminal through RRC signaling, MAC CE, DCI, or the like, or may be predefined, and thus, the fourth value is preset in the terminal, or may be determined by the terminal itself.

The eighth threshold may also be indicated by a network side, for example, the network side indicates the eighth threshold to the terminal through RRC signaling, MAC CE, DCI, or the like, that is, the terminal receives the eighth threshold, which may also be predefined and thus preset in the terminal. The eighth threshold may be in the form of an integer, or may be a ratio, for example, a ratio of the number of carriers whose time domain interval is greater than or equal to the sixth threshold to the total number of carriers.

In an embodiment, the first factor is determined to be a fifth value when there are overlapping carriers among the carriers and the number of overlapping carriers satisfies a ninth threshold.

Wherein, for the fifth value, it is different from the same situation that the difference and/or the sum of the numbers contained in the first factor is adopted, but a certain amplification is performed on the basis of the fifth value, which can also be understood as relaxation. Exemplarily, it is assumed that there are 9 carriers, there are carriers with overlapped time domains, and the number of overlapped carriers is 4, and is greater than 2 (i.e., a ninth threshold), at this time, when a difference and/or a sum of the numbers included in the first factor is used, a value of the first factor is 4, but complexity of implementation of terminal measurement is considered, that is, implementation capability of the terminal is considered, so as to reduce complexity of implementation of the terminal, and a value of the first factor may be 6.

In practical application, the fifth value may be indicated by a network side, for example, the network side indicates the fifth value to the terminal through RRC signaling, MAC CE, DCI, or the like, or may be predefined, and thus is preset in the terminal, or may be determined by the terminal itself.

The ninth threshold may also be indicated by the network side, for example, the network side indicates the ninth threshold to the terminal through RRC signaling, MAC CE, or DCI, and the like, that is, the terminal receives the ninth threshold, and may also be predefined, so as to be preset in the terminal. The ninth threshold may be in the form of an integer or a ratio, such as the ratio of the number of overlapped carriers to the total number of carriers.

In practical application, when the terminal determines the first factor according to the time domain position information of the measurement reference signals of different carriers, because the terminal needs a certain time period for processing the reference signals, if the two reference signals are adjacent to each other in the time domain, the terminal is likely to be unable to process the second (with the time sequence as an axis and the time being later) reference signal, and the measurement performance of the two reference signals is also likely to be unable to be ensured, so that the network side can indicate the carrier waves that the terminal can measure simultaneously and/or what are the carrier waves without overlapping time domains, thereby ensuring the measurement performance of the terminal.

Based on this, in an embodiment, the method may further include:

receiving third information;

determining the first factor using the third information.

Wherein the third information may include at least one of:

a time domain interval threshold of the SMTC;

a time domain interval threshold of the CSI-RS;

the SMTC and the CSI-RS are separated by a time domain threshold;

a time domain interval threshold of the PRS;

the time domain interval thresholds of the SMTC and the PRS;

and the time domain interval threshold of the CSI-RS and the PRS.

Specifically, third information indicated by the network side is received. In actual application, the network side may indicate the third information to the terminal through RRC signaling, MAC CE, DCI, or the like.

The time domain interval threshold of the SMTC refers to a time domain interval threshold between the SMTCs, and when the time domain interval of two SMTCs is greater than or equal to the threshold, the two SMTCs may be considered to be completely non-overlapping, or it may be understood that the terminal may independently process the two SMTCs, that is, measure the two SMTCs separately, that is, the terminal may measure the two SMTCs simultaneously.

The time domain interval threshold of the CSI-RS refers to a time domain interval threshold between the CSI-RSs, and when the time domain interval of two CSI-RSs is greater than or equal to the threshold, the two CSI-RSs are considered to be completely non-overlapping, or the two CSI-RSs may be considered to be processed by the terminal independently, that is, the two CSI-RSs are measured separately, that is, the terminal may measure the two CSI-RSs simultaneously.

The time domain interval threshold of the SMTC and the CSI-RS refers to a time domain interval threshold between the SMTC and the CSI-RS, and when the time domain interval between the SMTC and the CSI-RS is greater than or equal to the threshold, the two reference signals of the SMTC and the CSI-RS may be considered to be completely non-overlapping, or it may be understood that the terminal may independently process the two SMTC and CSI-RS, that is, measure the SMTC and CSI-RS separately, and the terminal may measure the two SMTC and CSI-RS simultaneously.

The time domain interval threshold of the PRS refers to a time domain interval threshold between the PRSs, and when the time domain interval of two PRSs is greater than or equal to the threshold, the two PRSs may be considered to be completely non-overlapping, or it may be understood that the terminal may independently process the two PRSs, that is, measure the two PRSs separately, that is, the terminal may measure the two PRSs simultaneously.

The time domain interval threshold of the SMTC and the PRS refers to a time domain interval threshold between the SMTC and the PRS, and when the time domain interval between the SMTC and the PRS is greater than or equal to the threshold, the two reference signals of the SMTC and the PRS are considered to be completely non-overlapping, or it can be understood that the terminal can independently process the two SMTC and PRS, that is, the SMTC and the PRS are measured separately, and the terminal can measure the two SMTC and PRS simultaneously.

The time domain interval threshold of the CSI-RS and the PRS refers to a time domain interval threshold between the CSI-RS and the PRS, and when the time domain interval between the CSI-RS and the PRS is greater than or equal to the threshold, the two reference signals of the CSI-RS and the PRS are considered to be completely non-overlapping, or it can be understood that the terminal can independently process the two CSI-RS and the PRS, that is, the CSI-RS and the PRS are measured separately, and the terminal can measure the two CSI-RS and the PRS simultaneously.

The value of the time interval threshold may be different according to different implementations of the terminal.

In practical application, the network side may issue measurement delay related information to the terminal, where the measurement delay related information may be understood as how long the network expects the terminal to complete measurement of N frequency points, where N is an integer greater than or equal to 1.

Based on this, in an embodiment, the method may further include:

receiving measurement delay related information sent by a network side;

and determining the measurement duration for completing the measurement by using the received measurement delay related information, namely the measurement duration for completing the measurement expected by the network side.

The network side may broadcast the measurement delay related information, and may also send the measurement delay related information to the terminal through an RRC signaling.

After the terminal acquires the measurement duration expected by the network side to finish measurement, the network side does not schedule the terminal when the terminal performs measurement, so that the network side can schedule the terminal in time. That is, after the terminal and the network side understand that the measurement duration is the same, the terminal and the network side can assist the network in scheduling.

The measurement delay related information may include a measurement duration (which may also be referred to as a measurement delay duration, and the name is not limited in this application embodiment), that is, the network side indicates the measurement duration. The measurement duration may be different according to different implementations of the terminal.

In practical application, the measurement duration may be determined by reducing the measurement duration, the first factor, the measurement duration of a single carrier, the reference period, and other factors.

In practical application, the total measuring time is related to at least one of the following factors:

the number of samples;

a reference signal;

MGRP；

the number of frequency bins.

Based on this, in one embodiment, the measurement duration is determined by one of the following formulas:

N1 x Ax N2；

N1 x max(A,B)x N2；

N1 x max(A,N3*B)x N2；

max(T1,N1*C)*N2；

max(T1,N1*max(B,C))*N2；

N1*B*N2；

max(T1,N1*max(C,D))*N2；

max(T1,N1*max(A,C,D))*N2；

wherein N1, N2 and N3 are integers greater than or equal to 1; t1 is a constant, a represents the measurement period of the secondary carrier (english can be expressed as measCycleSCell); b represents a discontinuous reception cycle period; c denotes a measurement period of the reference signal (may also be referred to as a period of the reference signal); d represents MGRP; max () represents a max function.

N1 is related to at least one of the following factors:

the number of samples;

positional relationships of SMTC and MGRP (fully overlapping, partially overlapping, fully non-overlapping);

SMTC relates to a positional relationship of reference symbols (which may also be referred to as reference signals) for Radio Link Management (RLM), beam Failure Detection (BFD), candidate Beam Detection (CBD), or layer 1 reference signal received power (L1-RSRP).

That is, in practical application, the value of N1 may be determined according to at least one of the above factors.

N2 is related to the number of frequency points and/or the number of subcarriers, etc. That is to say, in practical application, the value of N2 may be determined according to the number of frequency points and/or the number of subcarriers, etc.

N3 is a predefined integer, and N3 may be determined according to the implementation of the terminal (i.e., the processing capability of the terminal) in practical applications.

T1 is a fixed value and is a fixed duration, such as 200ms, 600ms, or 800ms. The value of T1 can be set as desired.

In practical application, the network side may configure the terminal differently, for example, configure different thresholds, configure different measurement delay related information, and the like, in consideration of the difference in the terminal processing capability (mainly, baseband processing capability).

Based on this, in an embodiment, the method may further include:

whether the terminal supports carrier measurement based on the first factor;

the terminal supports a frequency point or a frequency band combination or a CA combination which is measured based on the first factor;

the terminal may measure the time domain interval of the SMTC at the same time;

time domain intervals of CSI-RS measurement windows which can be measured by the terminal at the same time;

the terminal can measure the time domain interval of the SMTC and the CSI-RS measuring window simultaneously;

time domain intervals of PRSs that the terminal can measure simultaneously;

the terminal may measure a time domain interval of the CSI-RS and PRS measurement windows simultaneously.

Wherein the first time length can be set according to requirements.

The carrier measurement may include common-frequency measurement, pilot-frequency measurement, inter-system measurement, CA measurement, DC or multi-connection measurement, SCC measurement, and the like.

For the frequency band combination, the terminal may not support the relevant schemes for all the frequency band combinations, so the terminal may report the frequency band combination capable of supporting the scheme, and thus, after the network side knows the information, the terminal may be instructed to adopt the scheme of the embodiment of the present application when the measurement of the frequency points in the frequency band combination supported by the terminal is involved. When measuring the frequency points in the frequency band combination which is not supported by the terminal, the terminal can measure based on the scheme which is not enhanced, that is, the scheme of the embodiment of the application is not adopted for measurement.

For the time domain interval reported by the terminal, in the related technology, the measurement of the SMTC and/or the CSI-RS of different frequency points is performed in series. In the embodiment of the present application, the terminal reports the time domain interval, and in order to reduce the measurement duration, for the measurement of some frequency points that satisfy the time domain interval reported by the terminal (that is, satisfy the time domain condition reported by the terminal), based on the first factor, the measurement may be performed in a parallel manner or in a partially serial manner.

Here, for the serial mode, it is exemplarily assumed that 5 samples are required to complete the measurement of one frequency point, and each sample interval is T (T may be an SMTC period or a CSI-RS period). If the measurement of P frequency points is performed, the duration for completing the measurement of P frequency points is: 5 × t × p (for in the period of 5 × t × n, the terminal sequentially completes the measurement of each frequency point and then performs the measurement of the next frequency point (for example, after F1 is sampled for 5 times, F2 is sampled for 5 times, and so on), or the terminal performs the measurement in a staggered manner (for example, F1 is sampled once, F2 is sampled once until Fn is sampled once, and then F1 is sampled once again, and so on), depending on the terminal implementation.

The scheme provided by the embodiment of the application is as follows: based on the first factor, the measurement duration is reduced by performing parallel measurement or partial serial measurement on certain frequency points. Based on the parallel measurement, the total time length for completing the measurement of the P frequency points is 5 × t (applicable to the scenario in which the SMTC cycles and/or SMTC offsets of the P frequency points are the same). The total duration of completing the measurement of the P frequency points may also be max (5 × T1,5 × T2, \8230; 5 × Tn), which is suitable for scenes with different SMTC periods of the P frequency points (T1, T2, \8230; tn is the SMTC period of different frequency points). Based on the partial serial scheme, the method is suitable for a scene that SMTCs of different frequency points have certain offset in time domains and the terminal cannot receive the signals simultaneously, or even if the offsets of the SMTCs in the time domains are the same or similar, the total measurement time of the partial serial scheme is slightly longer than that of the parallel scheme but shorter than that of the complete serial scheme aiming at the measurement of P frequency points because the processing capacity of the terminal is limited and the terminal needs to process the signals in sequence after caching.

That is to say, according to the scheme adopted by the embodiment of the present application, the terminal performs parallel measurement (for example, considering that the time domain is not overlapped at all and/or the processing capability of the terminal) or partial serial measurement on the carriers based on the first factor.

According to the measuring method provided by the embodiment of the application, the terminal carries out measurement based on the first factor; the first factor is associated with at least one of first information and second information; the first information represents the time domain position relation of the reference signal of the carrier; the second information represents the number of carriers, and the scheme provided by the embodiment of the application considers the time domain position relationship of the reference signals among different carriers, so that the measurement time delay can be reduced during measurement in a high-speed mobile scene, and the measurement performance of the terminal is improved.

An embodiment of the present application further provides a measurement method, which is applied to a terminal, and as shown in fig. 2, the method includes:

step 201: performing a measurement based on the second factor; the second factor is associated with a secondary carrier measurement.

In an embodiment, the terminal measures the secondary carrier based on the second factor.

The scheme of the embodiment of the application can be applied to CA, double connection or multi-connection scenes.

In a high-speed rail scene, measurement time delay needs to be reduced, and a second factor is introduced in consideration of the fact that measurement needing a measurement interval exists and measurement needing no measurement interval exists in the measurement, so that the second factor is specifically related to whether the measurement needs the measurement interval or not.

Based on this, in an embodiment, the second factor may include at least one of:

the difference value between the total number of the carriers and the number of the auxiliary carriers needing to be measured; the total number of carriers may include a number of primary carriers (PCCs) and/or SCCs;

the number of subcarriers of an interval does not need to be measured;

a difference between the ninth value and the first carrier number, where the first carrier includes a secondary carrier in which the SMTC and the measurement interval completely overlap and/or a secondary carrier in which the SMTC and the measurement interval partially overlap, that is, the first carrier number includes the number of secondary carriers in which the SMTC and the measurement interval completely overlap and/or the number of secondary carriers in which the SMTC and the measurement interval partially overlap;

a second carrier number and a third carrier number, which may be understood as that the second factor includes the second carrier number and the third carrier number, or the second factor includes a sum of the second carrier number and the third carrier number, the second carrier includes an SMTC and a secondary carrier whose measurement interval is completely non-overlapping, that is, the second carrier number includes a number of the SMTC and a secondary carrier which is completely non-overlapping with the measurement interval, and the third carrier includes a number of the SMTC and a secondary carrier whose measurement interval is partially overlapping, that is, the third carrier number includes a number of the SMTC and a secondary carrier whose measurement interval is partially overlapping;

a difference value between a tenth value and a fourth carrier number, where the fourth carrier includes an auxiliary carrier in which the CSI-RS and the measurement interval are completely overlapped and/or an auxiliary carrier in which the CSI-RS and the measurement interval are partially overlapped, that is, the fourth carrier number includes the auxiliary carrier in which the CSI-RS and the measurement interval are completely overlapped and/or the auxiliary carrier in which the CSI-RS and the measurement interval are partially overlapped;

the fifth carrier number and the sixth carrier number may be understood that the second factor includes a fifth carrier number and a sixth carrier number, or the second factor includes a sum of a fifth carrier number and a sixth carrier number, where the fifth carrier includes CSI-RS and a secondary carrier whose measurement interval is completely non-overlapping, that is, the fifth carrier number includes a secondary carrier number where CSI-RS and measurement interval are completely non-overlapping; the sixth carrier includes the CSI-RS and the secondary carriers with partially overlapped measurement intervals, that is, the sixth carrier number includes the number of the secondary carriers with partially overlapped CSI-RS and measurement intervals;

a difference between the eighteenth value and a seventh carrier number, where the seventh carrier includes a secondary carrier where the PRS and the measurement interval completely overlap and/or a secondary carrier where the PRS and the measurement interval partially overlap, that is, the seventh carrier number includes a secondary carrier where the PRS and the measurement interval completely overlap and/or a secondary carrier where the PRS and the measurement interval partially overlap;

the eighth carrier number and the ninth carrier number may be understood that the second factor includes an eighth carrier number and a ninth carrier number, or the second factor includes a sum of the eighth carrier number and the ninth carrier number, where the eighth carrier includes PRS and a secondary carrier whose measurement interval is not overlapped completely, that is, the eighth carrier number includes a secondary carrier number where PRS and the measurement interval are not overlapped completely, and the ninth carrier includes a secondary carrier where PRS and the measurement interval are partially overlapped, that is, the ninth carrier number includes a secondary carrier where PRS and the measurement interval are partially overlapped.

Here, the second factor is a value in a high-speed rail scenario.

Accordingly, in a non-high-speed rail scenario, the second factor comprises one of:

the total number of auxiliary carriers;

the number of the subcarriers requiring measurement of the interval and the number of the subcarriers not requiring measurement of the interval may be understood as that the second factor includes the number of the subcarriers requiring measurement of the interval and the number of the subcarriers not requiring measurement of the interval, or the second factor includes the sum of the number of the subcarriers requiring measurement of the interval and the number of the subcarriers not requiring measurement of the interval;

at least two of the following or a sum of at least two of the following: number of subcarriers where SMTC and measurement interval completely overlap; the number of the secondary carriers with completely non-overlapping SMTC measurement intervals; the number of secondary carriers partially overlapped by the SMTC and the measurement interval;

at least two of the following or a sum of at least two of the following: the number of sub-carriers where the CSI-RS and the measurement interval are completely overlapped; the number of the auxiliary carrier waves with completely non-overlapping CSI-RS measurement intervals; the number of sub-carriers partially overlapped by the CSI-RS and the measurement interval;

at least two of the following or a sum of at least two of the following: the number of PRSs and the number of subcarriers where the measurement intervals completely overlap; the number of secondary carriers with completely non-overlapping PRS measurement intervals; the number of subcarriers where PRS and measurement interval partially overlap.

The eighth value refers to the total number of the secondary carriers, where the total number of the secondary carriers includes a sum of the number of the secondary carriers requiring measurement intervals and the number of the secondary carriers not requiring measurement intervals.

Here, the number of secondary carriers may be the number of network-configured secondary carriers. The secondary carrier may include at least one of:

Here, when the total number of the secondary carriers includes only the number of the secondary carriers where the SMTC and the measurement interval completely overlap, a value of the second factor is defined as 1. When the total number of the secondary carriers only contains the number of the secondary carriers partially overlapped by the SMTC and the measurement interval, the value of the second factor is defined as 1. And when the total number of the secondary carriers only comprises the number of the secondary carriers completely overlapped by the SMTC and the measurement interval and the number of the secondary carriers partially overlapped by the SMTC and the measurement interval, the value of the second factor is defined as 1.

a secondary carrier based on CSI-RS measurements;

a secondary carrier based on PRS measurements.

Here, it is considered that the same network may serve multiple scenarios at the same time, and different scenarios may consider different factors, so that the first factor has different values, for example, different first factor values are adopted for eMBB services, URLLC services, and mtc services; for example, different values of the second factor are adopted for high-speed (high-speed) and non-high-speed (non-high-speed) scenes.

the measurement of the target multiple carriers needs to be completed within a certain time length, which is related to the measurement time length of the single carrier, the second factor and other factors.

In practical application, the terminal needs to determine the second factor and then perform measurement based on the first factor.

Based on this, in an embodiment, as shown in fig. 2, the method may further include:

step 200: determining the second factor.

Specifically, the terminal may determine the second factor according to whether the terminal has a measurement requiring a measurement interval; the terminal may also determine the second factor according to whether the terminal has a measurement of a secondary carrier in which a reference signal and a measurement interval completely overlap; the terminal may also determine the second factor from network information.

Wherein, the determining the second factor according to whether the terminal has a measurement requiring a measurement interval means: the terminal autonomously determines whether a second factor is needed or not according to at least one of the following:

whether a measurement target or carrier (including PCC and/or SCC) requires a measurement interval;

the number of carriers (including PCC and/or SCC) that need to be measured for an interval;

the number of carriers (including PCC and/or SCC) of the measurement interval is not required.

And if the value of the second factor is needed in the scene of the second factor.

Correspondingly, the terminal autonomously determines the second factor according to whether the terminal has the reference signal and the measurement of the secondary carrier with the completely overlapped measurement interval.

Here, the reference signal includes at least one of:

SSB；

CSI-RS；

PRS。

the obtaining the second factor according to the network information means: the network side indicates the value of the second factor, and the network side may indicate the second factor through signaling, such as RRC signaling, MAC CE, DCI, or other signaling.

When the terminal autonomously determines the second factor, the second factor may be determined in the manner described above.

Specifically, in an embodiment, when there is a secondary carrier requiring a measurement interval or there is a measurement of a secondary carrier in which a reference signal and a measurement interval completely overlap, it is determined that the second factor is a sixth value. Here, the value of the second factor is a sixth value, and the sixth value may be a difference and/or a number included in the second factor in the high-speed rail scenario. For example, assuming that the total number of the secondary carriers is 3, and the number of the secondary carriers requiring the measurement interval is 1, in this case, the value of the second factor may be 3-1=2. For another example, assuming that the total number of the secondary carriers is 3, the number of smtc secondary carriers and the number of secondary carriers having completely overlapped measurement intervals are 1, the value of the second factor may be 3-1=2.

In practical application, when the value of the second factor is directly determined by using the above method, although the measurement performance may be improved (i.e., the measurement delay is reduced), the complexity of the terminal measurement may also be increased. Therefore, in order to take both the measurement performance and the complexity of the terminal implementation into consideration, the value of the second factor may not be the difference and/or the number included in the second factor.

Based on this, in an embodiment, when there is a secondary carrier requiring a measurement interval or there is a measurement of a secondary carrier in which a reference signal and the measurement interval completely overlap, and the number of the secondary carriers requiring the measurement interval satisfies a tenth threshold, it is determined that the second factor is a seventh value.

Wherein, for the seventh value, different from the same situation, the difference and/or number included in the second factor is adopted, and a certain amplification is performed on the basis, which can also be understood as relaxation. Illustratively, here, the value of the second factor is a sixth value, and the sixth value may be a difference and/or a number included in the second factor in the above-mentioned high-speed rail scenario. Exemplarily, assuming that the total number of the secondary carriers is 3 and the number of the secondary carriers requiring measurement interval is 1, at this time, when a value of the second factor is 3-1=2 may be obtained in a manner of a difference and/or a number included in the second factor, but considering complexity of implementation of terminal measurement, that is, considering implementation capability of a terminal, complexity of implementation of the terminal is reduced, and the value of the second factor may be 3. For another example, assuming that the total number of the secondary carriers is 3, the number of the smtc secondary carriers and the number of the secondary carriers whose measurement intervals are completely overlapped are 2, at this time, when the value of the second factor is 1 in a manner of the difference and/or the number included in the second factor, the complexity of implementing the terminal measurement is considered, that is, the implementation capability of the terminal is considered, so that the complexity of implementing the terminal is reduced, and the value of the second factor may be 2.

In practical applications, the seventh value may be indicated by a network side (or may be understood to be notified by the network side), for example, the network side may indicate the seventh value to the terminal through RRC signaling, MAC CE, DCI, or the like, or may be predefined, and thus, the seventh value may be preset in the terminal, or may be determined by the terminal itself.

The tenth threshold may also be indicated by a network side, for example, the network side indicates the tenth threshold to the terminal through RRC signaling, MAC CE, or DCI, and the like, that is, the terminal receives the tenth threshold, and may also be predefined, so as to be preset in the terminal.

When the secondary carrier measurement period (english may be expressed as measCycleSCell) is large, when there are many opportunities for measurement (SMTC, CSI-RS, measurement interval (MG, PRS)) in the secondary carrier measurement period, there is no need to consider the positional relationship between the reference signal and the MGRP.

Based on this, in an embodiment, the second factor includes at least one of:

when the measurement period of the auxiliary carrier is greater than or equal to an eleventh threshold, the value of the second factor is equal to an eleventh value;

when the secondary carrier measurement period is less than or equal to the twelfth threshold, the value of the second factor is equal to E/(E- (C/D)); wherein C represents a measurement period of the reference signal; d represents MGRP; e represents an eleventh value.

When the measurement period of the secondary carrier is greater than or equal to the eleventh threshold, it is indicated that the measurement opportunities are relatively few, so that the secondary carrier is measured as much as possible in each measurement period; when the measurement period of the secondary carrier is less than or equal to the tenth threshold, it is indicated that the measurement opportunities are more.

The eleventh threshold and the twelfth threshold may be set as needed. The eleventh threshold may be indicated by a network side, for example, the network side indicates the eleventh threshold to the terminal through RRC signaling, MAC CE, DCI, or the like, that is, the terminal receives the eleventh threshold, or may be predefined, and thus is preset in the terminal; accordingly, the twelfth threshold may be indicated by the network side, for example, the network side indicates the twelfth threshold to the terminal through RRC signaling, MAC CE, DCI, or the like, that is, the terminal receives the twelfth threshold, or may be predefined, and thus the twelfth threshold is preset in the terminal.

In practical applications, the value of the eleventh value may be 1.

In practical application, the network side may configure the terminal differently, for example, configure different thresholds, configure different values of the second factor, and the like, in consideration of different processing capabilities (mainly baseband processing capabilities) of the terminal.

Based on this, in an embodiment, the method may further include:

whether the terminal supports measurement based on the second factor;

and the terminal supports a frequency point or frequency band combination or carrier aggregation combination which is measured based on the second factor.

That is to say, in the embodiment of the present application, similar to the measurement based on the first factor, the terminal performs parallel measurement (for example, considering whether the measurement interval and/or the processing capability of the terminal is needed) or partial serial measurement on the carrier based on the second factor, so as to reduce the total duration of the measurement.
