Description

Technical Field

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

[0002] With the further development of 5G 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, ranging from 24.25 GHz to 52.6 GHz and 52.6 GHz to 71 GHz respectively. FR2 can improve the network capacity carrying capacity and ensure high-capacity business needs.

[0003] Signal measurement processes are involved in scenarios such as mobility switching, cell search, cell reselection, carrier aggregation, and dual connectivity. In related technologies, the terminal performs signal measurement based on fixed measurement capability parameters. In addition, the current measurement delay of the terminal on FR2 is relatively long. Longer measurement delays lead to more scheduling restrictions, resulting in throughput loss.

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

[0045] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0046] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0047] In order to make the objectives, technical solutions and advantages of the present disclosure more clearly understood, the present disclosure is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0048] In the related art, the larger measurement delay of the terminal leads to more scheduling restrictions, which results in a loss of throughput. How to reduce the measurement delay of the signal is an important issue.

[0049] In view of this, the present disclosure proposes a signal measurement method, device and terminal, which enhance the terminal capability and can effectively reduce the measurement delay of the terminal.

[0050] Figure 1 FIG. 1 is a flow chart of a signal measurement method according to some embodiments of the present disclosure. Figure 1 As shown, the signal measurement method includes steps S101 to 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 such as a measurement configuration (MeasConfig) or a measurement idle configuration (MeasIdleConfig) in RRC signaling. For example, when the terminal is in an RRC idle state (RRC_IDLE) or an RRC non-connected state (RRC_INACTIVE), the measurement configuration information is specified through the MeasIdleConfig information element.

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

[0056] In some embodiments, layer 3 measurements are performed using a signal measurement method. Layer 3 measurements may be intra-frequency measurements, inter-frequency measurements, or inter-RAT measurements. Layer 3 measurements may be performed without measurement gaps or with measurement gaps.

[0057] For example, a signal measurement method is performed in the following layer 3 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 reference signal to be measured is measured using the capability parameter corresponding to the reference signal to be measured in the capability of the first terminal to obtain a measurement result.

[0059] The terminal has a first terminal capability and a second terminal capability. The measurement time period corresponding to the first terminal capability is shorter than the 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 comprises a scaling factor for the measurement time period.

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

[0062] In some embodiments, the scaling factor of the measurement time period includes at least one of a receive beam scanning factor and a sampling number.

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

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

[0065] In some examples, when the frequency of the reference signal to be measured is between 52.6 GHz and 71 GHz, the value of the first receiving beam scanning coefficient is an integer less than 12, and the value of the second receiving beam scanning coefficient is 12. For example, the first receiving beam scanning coefficient can take a value within {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 integer combinations less than 12.

[0066] In some embodiments, the first terminal capability includes a first sampling number, 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, for the primary synchronization signal or secondary synchronization signal detection phase, and the frequency of the reference signal to be detected 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, when the terminal supports the FR2-1 frequency band (24.25 GHz to 52.6 GHz) and the power level 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 receiving beam scanning coefficient of the terminal is 8, then the proportional coefficient of the measurement time period corresponding to the first terminal capability is less than 40, and the proportional coefficient of the measurement time period corresponding to the second terminal capability is 40.

[0069] In some examples, for the primary synchronization signal or secondary synchronization signal detection phase, and the frequency of the reference signal to be measured 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, when the terminal supports the FR2-1 frequency band and the power level of the terminal is 2, 3, or 4, the first sampling number is an integer less than 3, and the second sampling number is 3. Moreover, the receiving beam scanning coefficient of the terminal is 8, and the proportional coefficient of the measurement time period corresponding to the first terminal capability is less than 24, and the proportional coefficient of the measurement time period corresponding to the second terminal capability is 24.

[0071] In some embodiments, in step S102, a capability parameter corresponding to the reference signal to be measured 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 reference signal to be measured. In step S102, a capability parameter corresponding to the reference signal to be measured is selected from the first terminal capabilities according to the frequency information of the reference signal to be measured.

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

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

[0075] In the embodiment of the present disclosure, by enabling the terminal to have multiple capabilities and selecting a first terminal capability from the multiple capabilities to measure the reference signal to be measured, the measurement 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 in 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 in the measurement is less than or equal to the measurement time period determined according to the measurement capability parameter. If so, 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 the TS 38.133 standard). If so, the measurement result is sent to the base station; otherwise, the measurement result is not sent to the base station.

[0080] In the disclosed embodiment, the above steps are used to implement the terminal's measurement of the reference signal to be measured, which can reduce the terminal's measurement delay and enhance the flexibility of the base station in scheduling, and is particularly suitable for layer 3 measurement.

[0081] Figure 2 FIG. 1 is a flow chart of a signal measurement method according to other embodiments of the present disclosure. Figure 2 As shown, the signal measurement method includes steps S201 to S205.

[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 disposed 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 the first terminal capability.

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

[0087] In some embodiments, whether to use the first terminal capability is determined in the following manner: after receiving the first indication information of the base station, determining to use the first terminal capability; otherwise, determining 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, whether to use the first terminal capability is determined as follows: when 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, determine to use the first terminal capability; otherwise, determine to use the second terminal capability.

[0089] For example, when the measurement scenario belongs to scenarios such as cell search, cell reselection, mobility handover, carrier aggregation measurements, 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 is a low-latency service, it is determined to use the first terminal capability.

[0091] If it is determined that the first terminal capability is used, step S203 is executed; otherwise, step S204 is executed.

[0092] In the embodiment of the present disclosure, by determining whether the conditions for using the first terminal capability are met, and then using the first terminal capability for measurement when the conditions for using the first terminal capability are met, it is possible to reduce latency while taking into account both the reliability and applicability of the measurement, thereby better meeting user needs.

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

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

[0095] In some examples, when the reference signal to be measured is a synchronization signal and a physical broadcast channel block, measuring the reference signal to be measured includes the following two measurement phases, namely, a phase for detecting a primary synchronization signal or a secondary synchronization signal, and a phase for measuring based on the synchronization signal and the physical broadcast channel block. In both measurement phases in this example, the capability parameters corresponding to the reference signal to be measured in the capability of the first terminal are used for measurement.

[0096] In some examples, when the reference signal to be measured is a synchronization signal and a physical broadcast channel block, measuring the reference signal to be measured includes the following three measurement phases, namely, a phase for detecting a primary synchronization signal (Primary Synchronization Signal, PSS) or a secondary synchronization signal (Secondary Synchronization Signal, SSS), a measurement phase based on a synchronization signal and a physical broadcast channel block (Synchronization Signal and PBCH block, SSB), and a phase for obtaining indexes of the synchronization signal and the physical broadcast channel block. In the three measurement phases in this example, the capability parameters corresponding to the reference signal to be measured in the capability of the first terminal are used for measurement.

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

[0098] In some embodiments, in step S203, in a portion of the measurement phase for measuring the reference signal to be measured, the reference signal to be measured is measured using the capability parameter in the first terminal capability corresponding to the reference signal to be measured.

[0099] In some examples, when the reference signal to be measured is a synchronization signal and a physical broadcast channel block, measuring the reference signal to be measured includes the following two measurement phases, namely, a phase for detecting the primary synchronization signal or the secondary synchronization signal, and a phase for measuring based on the synchronization signal and the physical broadcast channel block. In one of the two measurement phases, the measurement is performed using the capability parameters corresponding to the reference signal to be measured in the first terminal capability; in the other measurement phase, the measurement is performed using the capability parameters corresponding to the reference signal to be measured in the second terminal capability.

[0100] In the embodiment of the present disclosure, by adopting the first terminal capability in some measurement stages for measuring the reference signal to be measured, it is possible to reduce the measurement delay of the terminal while alleviating the adverse effects that may be caused by taking low-latency measurements in all measurement stages in certain cases, thereby improving the level of refined control of terminal measurements.

[0101] In some embodiments, when historical measurement results for the reference signal to be measured exist, the reference signal to be measured is measured using capability parameters in the first terminal capability corresponding to the reference signal to be measured during all measurement phases for measuring the reference signal to be measured.

[0102] In some embodiments, in the absence of historical measurement results for the reference signal to be measured, in a partial measurement phase for measuring the reference signal to be measured, the reference signal to be measured is measured using capability parameters in the first terminal capability that correspond to the reference signal to be measured; in another partial measurement phase for measuring the reference signal to be measured, the reference signal to be measured is measured using capability parameters in the second terminal capability that correspond to the reference signal to be measured.

[0103] In the embodiment of the present disclosure, by using the first terminal capability for measurement in all measurement stages when historical measurement results for the reference signal to be measured exist, and by using the first terminal capability for measurement in some measurement stages when historical measurement results for the reference signal to be measured do not exist, it is possible to reduce the measurement delay while ensuring a certain measurement accuracy and measurement reliability.

[0104] In some embodiments, the capability parameter comprises a scaling factor for the measurement time period.

[0105] For example, when the reference signals to be measured are synchronization signals and physical broadcast channel blocks, the proportional coefficient of the measurement time period includes at least one of a proportional coefficient of a time period for detecting a primary synchronization signal or a secondary synchronization signal, a proportional coefficient of a measurement period based on measurement of a synchronization signal and a physical broadcast channel block, and a proportional coefficient of a time period for obtaining indexes of synchronization signals and physical broadcast channel blocks.

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

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

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

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

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

[0111] In the disclosed embodiment, the above steps are used to implement the terminal's measurement of the reference signal to be measured, which can reduce the terminal's measurement delay and enhance the flexibility of the base station in scheduling, and is particularly suitable for layer 3 measurement.

[0112] Figure 3 FIG. 1 is a flow chart of a signal measurement method according to some further embodiments of the present disclosure. Figure 3 As shown, the signal measurement method includes 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 reference signal to be measured according to the measurement configuration information, and selects a capability parameter corresponding to the reference signal to be measured from the first terminal capability parameters.

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

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

[0117] The capability information (or referred to as second indication information) includes capability parameters in the first terminal capability corresponding to the reference signal to be tested.

[0118] In some embodiments, the first terminal capability includes a proportional coefficient of a first measurement time period, and the capability information includes a proportional coefficient of a measurement time period selected from the proportional coefficients of the first measurement time period and corresponding to the reference signal to be measured.

[0119] In some embodiments, the first terminal capability includes a first receive beam scanning coefficient, and the capability information includes a receive beam scanning coefficient in the first receive beam scanning coefficient that corresponds to the reference signal to be measured.

[0120] In some embodiments, the first terminal capability includes a first sampling number, and the capability information includes a sampling number in the first sampling number that corresponds to the reference signal to be tested.

[0121] In some embodiments, the terminal may report the terminal capability information through new parameters in the measurement and mobility parameters (MeasAndMobParameters). The new parameters may be one or more of supportedLowerScalingFactor, supportedLowerRxBeamSweepingFactor, and supportedLowerSampleNumber.

[0122] For example, for the reference signal to be tested in the FR2-1 frequency band, the first receive beam scanning coefficient takes an integer less than 8, such as {2, 4, 6} or {1, 2, 4, 6} or {0, 1, 2, 3, 4, 5, 6, 7} or other possible integer combinations less than 8. The terminal can report the first receive beam scanning coefficient 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 reference signal to be measured using the capability parameter in the first terminal capability that corresponds to the reference signal to be measured to obtain a measurement result.

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

[0126] For example, the terminal uses a proportional coefficient of the first measurement time period when executing at least one of the following measurement stages: a stage for detecting a primary synchronization signal (PSS) or a secondary synchronization signal (SSS), a stage for measuring a synchronization signal and a physical broadcast channel block (SSB), and a stage for obtaining indexes of synchronization signals and physical broadcast channel blocks.

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

[0128] In some examples, the terminal uses the first terminal capability to perform measurement in all measurement phases of a measurement of the reference signal to be measured. In some examples, the terminal uses the first terminal capability to perform measurement in part of the measurement phases of a measurement of the reference signal to be measured.

[0129] For example, in a cell search scenario, the layer 3 measurement process performed by the terminal includes the following measurement phases: PSS / SSS detection, SSB-based measurement, and obtaining the index of the measured SSB. If the terminal has measured the cell in the previous period of time, and the terminal has stored the historical measurement results of the cell, the terminal can use the first terminal capability in all three of the above measurement phases to measure the reference signal to be measured. If the terminal has not measured the cell in the previous period of time, and the terminal does not have the historical measurement results of the cell, the terminal can use the first terminal capability in some of the three measurement phases to measure the reference signal to be measured. For example, the terminal can first use the second terminal capability to perform the measurement phase of PSS / SSS detection and the measurement phase based on SSB, and after obtaining a certain time, frequency, and beam information, use the first terminal capability to perform the measurement phase of obtaining the index of the measured SSB.

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

[0131] For example, the base station determines the latest allowed time for the base station to receive the measurement result based on the time period of the terminal performing measurement; the base station compares the latest allowed time with the time when the measurement result is actually received; if the latest allowed time is greater than or equal to the time when the measurement result is actually received, the measurement result is determined to be valid; otherwise, the measurement result is determined to be invalid.

[0132] In the disclosed embodiment, the above steps are used to implement the terminal's measurement of the reference signal to be measured, which can reduce the terminal's measurement delay and enhance the flexibility of the base station in scheduling, and is particularly suitable for layer 3 measurement.
