Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of communication, and in particular, to a signal measurement method, device and terminal. BACKGROUND

[0002] With the further development of 5G networks and 6G networks, the demand for spectrum is increasing. Frequency Range 2 (FR2) is one of the frequency ranges specified by 5G New Radio (NR). FR2 includes two frequency ranges, FR2-1 and FR2-2, which range from 24.25 GHz to 52.6 GHz and from 52.6 GHz to 71 GHz, respectively. FR2 can improve network capacity carrying capacity and guarantee high-capacity service demand.

[0003] Mobility handover, cell search, cell reselection, carrier aggregation, dual connectivity and other scenarios involve signal measurement procedures. In related technologies, a terminal performs signal measurement based on fixed measurement capability parameters. Moreover, the current terminal has a long measurement delay when measuring on FR2. The long measurement delay results in more scheduling restrictions, thereby causing throughput loss. SUMMARY

[0041] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. Note that the relative arrangement, numerical expressions, and numerical values of components and steps set forth in these embodiments are not limiting to the scope of the present disclosure unless otherwise specifically stated.

[0042] It should be understood, however, that the sizes of the various portions shown in the drawings are chosen primarily for convenience and clarity of presentation, and are not intended to limit the scope of the present disclosure.

[0043] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the scope of the present disclosure, its application, or uses.

[0044] Techniques, methods, and apparatus known to those of ordinary skill in the relevant art can not be discussed in detail herein, but should be considered part of the specification as appropriate.

[0045] In all of the examples shown and discussed herein, any specific values should be interpreted as merely illustrative and not as a limitation on the scope of the exemplary embodiments. Thus, other examples of the exemplary embodiments can have different values.

[0046] It should be noted that like references and characters herein relate to like items throughout the figures, and once an item is defined in one figure, it need not be discussed further in subsequent figures.

[0047] In order to make the purposes, technical solutions, and advantages of the present disclosure clearer, the present disclosure is further described in detail below with reference to specific embodiments and in conjunction with the accompanying drawings.

[0048] In the related art, more scheduling restrictions are caused by a large measurement delay of a terminal, thereby causing a loss of throughput. How to reduce the measurement delay of a signal is an important problem.

[0049] In view of this, the present disclosure provides a signal measurement method, device, and terminal, which enhances the terminal capability and effectively reduces the measurement delay of the terminal.

[0050] Figure 1 A flowchart of a signal measurement method according to some embodiments of the present disclosure is shown. As shown in Figure 1 The signal measurement method includes steps S101-S103.

[0051] In step S101, measurement configuration information of a reference signal to be measured is received from a base station.

[0052] In some embodiments, the signal measurement method is performed by a terminal or a signal measurement device disposed on the terminal.

[0053] In some embodiments, the terminal receives measurement configuration information sent by the base station through Radio Resource Control (RRC) signaling.

[0054] In some examples, the base station specifies the measurement configuration information through an information element (information element) such as MeasConfig in RRC signaling, or MeasIdleConfig. For example, when the terminal is in RRC idle state (RRC_IDLE) or RRC inactive state (RRC_INACTIVE), the measurement configuration information is specified through the MeasIdleConfig information element.

[0055] In some embodiments, the measurement configuration information includes measurement objects, measurement result (or measurement report) configuration, measurement identities, measurement gap configuration, and the like. For example, the measurement object includes the frequency, time location, and subcarrier spacing of the reference signal to be measured, and the like. For example, the measurement result configuration includes the standard for triggering the terminal to send the measurement result, such as whether the measurement result is periodically reported or reported after a measurement event is triggered.

[0056] In some embodiments, the measurement method using the signal is used to perform layer three measurement. The layer three measurement can be intra-frequency measurement, inter-frequency measurement, or inter-RAT measurement. The layer three measurement can be performed without measurement gaps, or with measurement gaps.

[0057] For example, the measurement method of the signal is performed in the following layer three measurement scenarios: intra-frequency measurements without measurement gaps, intra-frequency measurements with measurement gaps, inter-frequency measurements without measurement gaps, inter-frequency measurements with measurement gaps, and inter-RAT measurements.

[0058] In step S102, the to-be-measured reference signal is measured by using a capability parameter corresponding to the to-be-measured reference signal in the first terminal capability, to obtain a measurement result.

[0059] The terminal has a first terminal capability and a second terminal capability. A measurement time period corresponding to the first terminal capability is less than a measurement time period corresponding to the second terminal capability. The first terminal capability includes one or more capability parameters, and the second terminal capability includes one or more capability parameters.

[0060] In some embodiments, the capability parameter includes a proportion coefficient of the measurement time period.

[0061] In some embodiments, the to-be-measured reference signal is a synchronization signal and a physical broadcast channel block. In these embodiments, the proportion coefficient of the measurement time period includes at least one of a proportion coefficient of a time period for primary synchronization signal or secondary synchronization signal detection, a proportion coefficient of a measurement period based on synchronization signal and physical broadcast channel block measurement, and a proportion coefficient of a time period for obtaining an index of the synchronization signal and the physical broadcast channel block.

[0062] In some embodiments, the proportion coefficient of the measurement time period includes at least one of a receive beam sweeping coefficient and a sampling number.

[0063] In some embodiments, the first terminal capability includes a first receive beam sweeping coefficient, the second terminal capability includes a second receive beam sweeping coefficient, and the first receive beam sweeping coefficient and the second receive beam sweeping coefficient have different values.

[0064] In some examples, in a case where the frequency of the to-be-tested reference signal is between 24.25 GHz and 52.6 GHz, the first receive beam scanning coefficient takes an integer less than 8, and the second receive beam scanning coefficient takes 8. For example, the first receive beam scanning coefficient can take a value in {2, 4, 6} or {1, 2, 4, 6} or {0, 1, 2, 3, 4, 5, 6, 7} or other possible combinations of integers less than 8.

[0065] In some examples, in a case where the frequency of the to-be-tested reference signal is between 52.6 GHz and 71 GHz, the first receive beam scanning coefficient takes an integer less than 12, and the second receive beam scanning coefficient takes 12. For example, the first receive beam scanning coefficient can take a value in {2, 4, 6, 8, 10} or {1, 2, 4, 6, 8, 10} or {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11} or other possible combinations of integers less than 12.

[0066] In some embodiments, the first terminal capability includes a first sampling number, and the second terminal capability includes a second sampling number, and the first sampling number is different from the second sampling number.

[0067] In some examples, in a case where the frequency of the to-be-tested reference signal is between 24.25 GHz and 52.6 GHz, the first sampling number is an integer less than 5, and the second sampling number is 5.

[0068] For example, in a case where the terminal supports the FR2-1 frequency band (24.25 GHz to 52.6 GHz) and the power class of the terminal is 1 or 5, the first sampling number is an integer less than 5, and the second sampling number is 5. Moreover, the receive beam scanning coefficient of the terminal is 8, and the proportion coefficient of the measurement time period corresponding to the first terminal capability is less than 40, and the proportion coefficient of the measurement time period corresponding to the second terminal capability is 40.

[0069] In some examples, in a case where the frequency of the to-be-tested reference signal is between 24.25 GHz and 52.6 GHz, the first sampling number is an integer less than 3, and the second sampling number is 3.

[0070] For example, in a case where the terminal supports the FR2-1 frequency band and the power class of the terminal is 2 or 3 or 4, the first sampling number is an integer less than 3, and the second sampling number is 3. Moreover, the receive beam scanning coefficient of the terminal is 8, and the proportion coefficient of the measurement time period corresponding to the first terminal capability is less than 24, and the proportion coefficient of the measurement time period corresponding to the second terminal capability is 24.

[0071] In some embodiments, in step S102, the capability parameter corresponding to the to-be-measured reference signal is selected from the first terminal capability according to the measurement configuration information.

[0072] For example, the measurement configuration information includes frequency information of the to-be-measured reference signal, and in step S102, the capability parameter corresponding to the to-be-measured reference signal is selected from the first terminal capability according to the frequency information of the to-be-measured reference signal.

[0073] For example, the measurement configuration information includes measurement scenario information (such as intra-frequency measurement, inter-frequency measurement, etc.) of the to-be-measured reference signal. In step S102, the capability parameter corresponding to the to-be-measured reference signal is selected from the first terminal capability according to the measurement scenario information.

[0074] For example, in step S102, the capability parameter corresponding to the to-be-measured reference signal is selected from the first terminal capability according to the frequency information of the to-be-measured reference signal and the power class information of the terminal.

[0075] In the embodiments of the present disclosure, by enabling the terminal to have multiple capabilities and selecting the first terminal capability from the multiple capabilities, the measurement time delay can be reduced.

[0076] In step S103, the measurement result is sent to the base station.

[0077] In some embodiments, after obtaining the measurement result through step S102, the terminal sends the measurement result to the base station.

[0078] In some embodiments, after obtaining the measurement result through step S102, the terminal determines whether the time consumed by the measurement is less than or equal to the time period of the measurement determined according to the measurement capability parameter. If yes, the measurement result is sent to the base station; otherwise, the measurement result is not sent to the base station.

[0079] In some embodiments, after obtaining the measurement result through step S102, the terminal determines whether the measurement accuracy meets the accuracy requirement (for example, the accuracy requirement defined in TS 38.133 standard). If yes, the measurement result is sent to the base station; otherwise, the measurement result is not sent to the base station.

[0080] In the embodiments of the present disclosure, the measurement of the to-be-measured reference signal by the terminal is realized through the above steps, the measurement time delay of the terminal can be reduced, the flexibility of the scheduling by the base station is enhanced, and the method is especially suitable for layer three measurement.

[0081] Figure 2 A flowchart of a signal measurement method according to some other embodiments of the present disclosure is shown. As shown in FIG. 2, the signal measurement method includes steps S201 to S205. Figure 2

[0082] ​In step S201, measurement configuration information of a reference signal to be measured is received from a base station.

[0083] In some embodiments, the signal measurement method is performed by a terminal or a signal measurement device provided on the terminal.

[0084] In some embodiments, the terminal receives measurement configuration information sent by the base station through Radio Resource Control (RRC) signaling.

[0085] In step S202, it is determined whether to use a first terminal capability.

[0086] In some embodiments, the terminal has the first terminal capability and a second terminal capability. The measurement time period corresponding to the first terminal capability is smaller than the measurement time period corresponding to the second terminal capability.

[0087] In some embodiments, it is determined whether to use the first terminal capability according to the following manner: after receiving first indication information of the base station, it is determined to use the first terminal capability; otherwise, it is determined to use the second terminal capability. The first indication information is used to instruct the terminal to use the first terminal capability.

[0088] In some embodiments, it is determined whether to use the first terminal capability according to the following manner: in the case that the measurement scenario belongs to a specified category of measurement scenarios, or the service type used by the terminal belongs to a specified category of service types, it is determined to use the first terminal capability; otherwise, it is determined to use the second terminal capability.

[0089] For example, when the measurement scenario belongs to scenarios such as cell search, cell re-selection, mobility handover, carrier aggregation measurement, beam management, link recovery, and radio link monitoring (RLM), it is determined to use the first terminal capability.

[0090] For example, when the service type used by the terminal belongs to a low-latency service, it is determined to use the first terminal capability.

[0091] In the case of determining to use the first terminal capability, step S203 is performed; otherwise, step S204 is performed.

[0092] In the embodiments of the present disclosure, by judging whether the condition of using the first terminal capability is met, and using the first terminal capability to perform measurement when the condition of using the first terminal capability is met, the reliability and applicability of measurement can be considered while reducing the time delay, and the user demand can be better met.

[0093] In step S203, the to-be-measured reference signal is measured by using the capability parameter corresponding to the to-be-measured reference signal in the first terminal capability, to obtain a measurement result.

[0094] In some embodiments, in step S203, the to-be-measured reference signal is measured by using the capability parameter corresponding to the to-be-measured reference signal in the first terminal capability in all measurement stages of measuring the to-be-measured reference signal.

[0095] In some examples, when the to-be-measured reference signal is a synchronization signal and a physical broadcast channel block, the measurement of the to-be-measured reference signal includes two measurement stages, i.e., a stage for primary synchronization signal or secondary synchronization signal detection, and a stage for measurement based on the synchronization signal and the physical broadcast channel block. In the two measurement stages in this example, the measurement is performed by using the capability parameter corresponding to the to-be-measured reference signal in the first terminal capability.

[0096] In some examples, when the to-be-measured reference signal is a synchronization signal and a physical broadcast channel block, the measurement of the to-be-measured reference signal includes three measurement stages, i.e., a stage for primary synchronization signal (PSS) or secondary synchronization signal (SSS) detection, a stage for measurement based on the synchronization signal and the physical broadcast channel block (SSB), and a stage for obtaining an index of the synchronization signal and the physical broadcast channel block. In the three measurement stages in this example, the measurement is performed by using the capability parameter corresponding to the to-be-measured reference signal in the first terminal capability.

[0097] In the embodiments of the present disclosure, by using the first terminal capability to perform measurement in all measurement stages of measuring the to-be-measured reference signal, the measurement time delay of the terminal can be further reduced.

[0098] In some embodiments, in step S203, the to-be-measured reference signal is measured by using the capability parameter corresponding to the to-be-measured reference signal in the first terminal capability in part of the measurement stages of measuring the to-be-measured reference signal.

[0099] In some examples, when the to-be-measured reference signal is a synchronization signal and physical broadcast channel block, the measurement of the to-be-measured reference signal includes two measurement stages, i.e., a stage for primary synchronization signal or secondary synchronization signal detection and a stage for measurement based on the synchronization signal and physical broadcast channel block. In one of the two measurement stages, the measurement is performed by using the capability parameter corresponding to the to-be-measured reference signal in the first terminal capability; in the other measurement stage, the measurement is performed by using the capability parameter corresponding to the to-be-measured reference signal in the second terminal capability.

[0100] In the embodiments of the present disclosure, by using the first terminal capability in the part of the measurement stages for the measurement of the to-be-measured reference signal, the adverse effects caused by the low-latency measurement in all the measurement stages in some cases can be alleviated, and the fine control level of the terminal measurement is improved.

[0101] In some embodiments, when there is a historical measurement result for the to-be-measured reference signal, the measurement of the to-be-measured reference signal is performed by using the capability parameter corresponding to the to-be-measured reference signal in the first terminal capability in all the measurement stages for the measurement of the to-be-measured reference signal.

[0102] In some embodiments, when there is no historical measurement result for the to-be-measured reference signal, the measurement of the to-be-measured reference signal is performed by using the capability parameter corresponding to the to-be-measured reference signal in the first terminal capability in part of the measurement stages for the measurement of the to-be-measured reference signal, and the measurement of the to-be-measured reference signal is performed by using the capability parameter corresponding to the to-be-measured reference signal in the second terminal capability in another part of the measurement stages for the measurement of the to-be-measured reference signal.

[0103] In the embodiments of the present disclosure, by using the first terminal capability in all the measurement stages for the measurement of the to-be-measured reference signal when there is a historical measurement result for the to-be-measured reference signal, and by using the first terminal capability in part of the measurement stages for the measurement of the to-be-measured reference signal when there is no historical measurement result for the to-be-measured reference signal, the measurement latency can be reduced while the measurement accuracy and reliability are ensured.

[0104] In some embodiments, the capability parameter includes a proportionality coefficient of a measurement time period.

[0105] For example, when the to-be-measured reference signal is a synchronization signal and physical broadcast channel block, the proportionality coefficient of the measurement time period includes at least one of a proportionality coefficient of a time period for primary synchronization signal or secondary synchronization signal detection, a proportionality coefficient of a measurement period for measurement based on the synchronization signal and physical broadcast channel block, and a proportionality coefficient of a time period for obtaining an index of the synchronization signal and physical broadcast channel block.

[0106] In some embodiments, the scaling factor of the measurement time period comprises at least one of a receive beam sweeping factor and a sampling number.

[0107] In step S204, the to-be-measured reference signal is measured by using the capability parameter corresponding to the to-be-measured reference signal in the second terminal capability, to obtain a measurement result.

[0108] In some embodiments, step S204 is performed after it is determined that the first terminal capability is not used.

[0109] In step S205, the measurement result is sent to the base station.

[0110] In some embodiments, the terminal sends the measurement result to the base station after obtaining the measurement result.

[0111] In the embodiments of the present disclosure, the measurement of the to-be-measured reference signal by the terminal is realized through the above steps, which can reduce the measurement delay of the terminal and enhance the flexibility of the scheduling of the base station, and is especially suitable for layer three measurement.

[0112] Figure 3 A flowchart of a signal measurement method according to still another embodiment of the present disclosure is shown in FIG. 3. Figure 3 As shown in FIG. 3, the signal measurement method comprises steps 301 to 303.

[0113] In step 301, the base station sends measurement configuration information to the terminal.

[0114] In some embodiments, after receiving the measurement configuration information, the terminal determines the to-be-measured reference signal according to the measurement configuration information, and selects the capability parameter corresponding to the to-be-measured reference signal from the first terminal capability parameter.

[0115] In step 302, the terminal sends capability information to the base station.

[0116] In some embodiments, after selecting the capability parameter corresponding to the to-be-measured reference signal from the first terminal capability, the terminal sends the capability information to the base station.

[0117] The capability information (or referred to as second indication information) comprises the capability parameter corresponding to the to-be-measured reference signal in the first terminal capability.

[0118] In some embodiments, the first terminal capability comprises a scaling factor of a first measurement time period, and the capability information comprises a scaling factor of a measurement time period corresponding to the to-be-measured reference signal selected from the scaling factor of the first measurement time period.

[0119] In some embodiments, the first terminal capability comprises a first receive beam sweeping factor, and the capability information comprises a receive beam sweeping factor corresponding to the to-be-measured reference signal in the first receive beam sweeping factor.

[0120] In some embodiments, the first terminal capability comprises a first sample number, and the capability information comprises a sample number corresponding to the to-be-measured reference signal in the first sample number.

[0121] In some embodiments, the terminal can report the terminal capability information through a new parameter in MeasAndMobParameters. The new parameter can be one or more of supportedLowerScalingFactor, supportedLowerRxBeamSweepingFactor, and supportedLowerSampleNumber.

[0122] For example, for a to-be-measured reference signal of FR2-1 frequency band, the first receive beam sweeping factor takes an integer less than 8, such as it can take a value in {2, 4, 6} or {1, 2, 4, 6} or {0, 1, 2, 3, 4, 5, 6, 7} or other possible combinations of integers less than 8. The terminal can report the first receive beam sweeping factor through the new parameter supportedLowerRxBeamSweepingFactor, and report it in the form of an enumerated value (ENUMERATED) (for example, {2, 4, 6} or {1, 2, 4, 6} or {0, 1, 2, 3, 4, 5, 6, 7} or other combinations) or in the form of a value range (for example, maxNumberRxBeamSweepingFactor = 7).

[0123] In step 303, the terminal sends the measurement result to the base station.

[0124] In some embodiments, the terminal measures the to-be-measured reference signal by using a capability parameter corresponding to the to-be-measured reference signal in the first terminal capability to obtain the measurement result.

[0125] In some examples, the first terminal capability comprises a scaling factor of a first measurement time period.

[0126] For example, the terminal adopts the scaling factor of the first measurement time period when performing at least one of the following measurement stages: a stage for primary synchronization signal (PSS) or secondary synchronization signal (SSS) detection, a stage for synchronization signal and PBCH block (SSB) based measurement, and a stage for acquiring an index of the synchronization signal and PBCH block.

[0127] In some examples, the scaling factor of the first measurement time period includes at least one of a first receive beam sweeping factor and a first number of samples.

[0128] In some examples, the terminal adopts the first terminal capability to perform measurement on the to-be-measured reference signal in all measurement stages. In some examples, the terminal adopts the first terminal capability to perform measurement on the to-be-measured reference signal in part of the measurement stages.

[0129] For example, in a cell search scenario, the layer three measurement procedure performed by the terminal includes the following measurement stages: PSS / SSS detection, SSB based measurement, and acquiring an index of the measured SSB. If the terminal has measured the cell in a previous period of time, and the terminal has stored the historical measurement result of the cell, the terminal can adopt the first terminal capability to perform measurement on the to-be-measured reference signal in all of the above three measurement stages. If the terminal has not measured the cell in a previous period of time, and the terminal has no historical measurement result of the cell, the terminal can adopt the first terminal capability to perform measurement on the to-be-measured reference signal in part of the above three measurement stages. For example, the terminal can first perform the measurement stages of PSS / SSS detection and SSB based measurement by using the second terminal capability, and then perform the measurement stage of acquiring an index of the measured SSB by using the first terminal capability after acquiring certain time, frequency and beam information.

[0130] In some embodiments, the method for measuring the signal further includes: calculating, by the base station, a time period for the terminal to perform measurement according to the capability indication information; determining, by the base station, whether the measurement result is valid according to the time period for the terminal to perform measurement.

[0131] For example, the base station determines a latest allowed time for the base station to receive the measurement result according to the time period for the terminal to perform measurement; the base station compares the latest allowed time with an actual time of receiving the measurement result; if the latest allowed time is greater than or equal to the actual time of receiving the measurement result, the base station determines that the measurement result is valid; otherwise, the base station determines that the measurement result is invalid.

[0132] In the embodiments of the present disclosure, the measurement of the terminal on the to-be-measured reference signal is realized through the above steps, the measurement time delay of the terminal can be reduced, and the flexibility of the scheduling of the base station is enhanced, which is especially suitable for layer three measurement.
