    TECHNICAL FIELD
    [001] The disclosure concerns the technical field of digital mobile communications and, in particular, a method for reporting measurement capability and a User Equipment (UE). BACKGROUND
    [002] In cellular mobile communication systems, cell reselection and handover are important functions. To easily achieve the new cell selection, the UE needs to measure the signal quality of the different cells so as to select an appropriate cell to reside. After the UE connects to the network in a given cell, the UE still needs to measure the signal quality of the cells adjacent to the cell in order to select an appropriate cell for the handover to fulfill the mobility requirement.
    [003] The specific process where the UE takes the measurement in the connected state includes: one side of the network sends a measurement control message to the UE, where the measurement control message includes a Measurement Identity (MID - Measurement Identity ), a Measurement Object (MO - Measurement Object), a Report Configuration (RC - Report Configuration) and other related measurement properties. The UE performs the measurement according to the measurement object and the report setting in the measurement control message, and generates a measurement report according to the measurement result to report to the network side. Generally, each measurement task includes a MID, an MO property (e.g. a carrier (a carrier center frequency point, i.e. Absolute Radio Frequency Channel Number (ARFCN), a list of neighboring cells or the like) and the RC property (for example, an event-triggered report or a normal report, with the triggering event being defined by the triggering conditions (A1, A2, etc.), and the threshold, deviation, and Trigger Time (TTT - Time To Trigger) related to trigger conditions or the like.) Due to the different carrier frequency on which the measurement object is held, the measurement task includes equal frequency measurement and frequency measurement different, i.e. the measurement task corresponds to the same frequency measurement if the carrier frequency of the measurement object and that of the service cell (the carrier frequency of the service cell refers to the central frequency point in which the UE communicates with the service cell) are the same, and the measurement task corresponds to the measurement of different frequency if the carrier frequency of the measurement object and that of the service cell are different, the different frequency measurement refers to the measurement task in which the measurement object does not correspond to E-UTRAN, for example, a measurement task in which the measurement object corresponds to a Universal Mobile Telecommunication System (UMTS), a Multiple Access by Code Division (CDMA2000 - Code Division Multiple Access) and a GSM EDGE Radio Access Network (GERAN - GSM EDGE Radio Access Network). For measurement in an equal frequency measurement task, the UE can directly perform measurement without a measurement gap; for measurement in a different system and frequency measurement task, the UE needs to ask the network side to configure a measurement interval, i.e. to designate a period of time, in which the UE temporarily stops communicating with the service cell and perform different system measurement and different frequency. If a measurement interval needs to be configured, the base station configures the measurement interval for the UE via an RRC reconfiguration message.
    [004] In LTE, the UE communicates with the base station through a single cell when it is in the connected state, when the UE performs measurement in the measurement task of different system and different frequency, the base station determines the configuration of the measurement interval for the UE according to the capacity reported by the UE, the UE performs the measurement of different system and different frequency at the time specified by the measurement interval, and the base station will not schedule the UE. Fig. 1 is a flowchart of a UE reporting measurement capability in related technologies, as illustrated in Fig. 1, the base station requests the UE to report the UE's measurement capability via a capability inquiry message from the UE. UE, the UE reports the UE's measurement capability to the base station via a UE capability information message containing the capability on whether or not a measurement interval is required for the UE to perform the different system measurement task and different frequency, specifically: when the UE is at a certain frequency in the frequency band x, it is measured whether or not a measurement interval is needed for the UE at the frequency in the frequency band y, where y can be equal to x, at that time, it is indicated whether or not a measurement interval is required for the UE to measure the different frequency in the x-frequency band when the UE is in a certain frequency in the x-frequency band. The frequency band refers to the number of a particular uplink and downlink frequency band, for example, as mentioned in Table 5.5-1 at 36.101 (Evolved Universal Terrestrial Radio Access Network (E-UTRAN) Radio Access); radio reception and transmission UE), and frequency band 1 represents an uplink frequency band 1920MHz to 1980MHz and a downlink frequency band 2110MHz to 2170MHz in FDD.
    [005] To provide a higher data rate for mobile users, Advanced Long Term Evolution (LTE-A - Long Term Evolution Advance) proposes Carrier Aggregation (CA - Carrier Aggregation) technology, whose objective is to provide a higher bandwidth for the UEs with the corresponding capacity and improve the peak rate of the UEs. In LTE, the maximum downlink transmission bandwidth supported by the system is 20MHz, while carrier aggregation has to aggregate two or more Component Carriers (CC - Component Carriers) to support a transmission bandwidth greater than 20MHz, but not more than 100MHz. Carrier aggregation can include continuous carrier aggregation and discontinuous carrier aggregation depending on whether or not the CCs are continuous in the frequency domain, therefore, in carrier aggregation, the UE can communicate with the base station through a diversity of cells simultaneously after entering the connected state, when the UE performs measurement in the measurement task of different system and different frequency, the base station determines the setting of a measurement interval for the UE, the UE performs the system measurement and different frequency in the time specified by the measurement interval, and the base station will not schedule the UE.
    [006] The defined intra-system metering events currently supported by LTE-A are:
    [007] Event A1: The signal quality of the primary or secondary service cell is above a specified threshold.
    [008] Event A2: The signal quality of the primary or secondary service cell is below a specified threshold.
    [009] Event A3: The signal quality of the neighboring cell is superior to the signal quality of the primary serving cell by a specified deviation.
    [0010] Event A4: Neighbor cell signal quality is higher than specified threshold.
    [0011] Event A5: The signal quality of the primary serving cell is less than a specified threshold 1, and the signal quality of the neighboring cell is greater than a specified threshold 2.
    [0012] Event A6: Neighbor cell signal quality is superior to secondary serving cell signal quality by a specified deviation.
    [0013] The defined intersystem metering events currently supported by LTE-A are:
    [0014] Event B1: The signal quality of the neighboring cell is higher than the specified threshold.
    [0015] Event B2: The signal quality of the primary serving cell is less than the specified threshold 1, and the signal quality of the neighboring cell is greater than the specified threshold 2.
    [0016] To support carrier aggregation, the radio frequency structure of the UE must meet the corresponding requirements. In LTE-A, there are two types of UE receivers, where one type is a single receiver that supports a bandwidth greater than 20MHz and supports continuous carrier aggregation only in the equal frequency band. The other type is a diversity of receivers, each of which supports a bandwidth of 20MHz or less and supports aggregation of continuous carriers in the same frequency band and aggregation of discontinuous carriers in the different frequency band. As the UE receiver structure is implemented internally, according to current common sense, the base station algorithm needs to protect these internal structures, therefore, in some cases, the base station cannot determine whether it is necessary or not. a measurement interval for the UE to perform measurement of different system and different frequency. Fig. 2 is a diagram of building a UE in one embodiment, as illustrated in Fig. 2, the UE has two independent receivers, which respectively support a bandwidth of 20M, the receiver 1 supports operation in the frequency band 1/2/3, receiver 2 supports operation in frequency band 1/4/5, if the base station only configures a CC in frequency band 1 for UE, UE can allow receiver 1 or receiver 2 enters the working state, further, if receiver 1 is used, a measurement interval is required for the UE to perform different frequency measurement in frequency band 2/3, but a measurement interval is not required for the UE to perform different frequency measurement in frequency band 2/3. UE perform different frequency measurement in frequency band 4/5. However, in carrier aggregation, the UE can communicate with the originating base station through a plurality of cells simultaneously after entering the connected state, therefore, if the UE still reports as in LTE, since the UE cannot predict which CCs the base station will configure for the UE for the aggregation, so as to consider the whole situation and avoid the problem of the base station not configure a measurement interval when the measurement interval is needed, the UE will very much need a measurement interval for all frequency bands to perform the measurement, thus resulting in the base station setting a measurement interval when the UE does not need the measurement interval, and according to the definition of the measurement interval, the base station will not schedule the UE at the time specified by the measurement interval, although the base station may fully schedule the UE at the time period and, as a consequence, a measurement interval unnecessary action will certainly cause a great waste of resources.

SUMMARY
    [0018] Accordingly, the main purpose of the disclosure is to provide a method for reporting the measurement capability and a UE thereof, whereby the UE's measurement capability can be reported accurately, so that the possible waste of resources caused can be avoided when the UE is scheduled to perform the measurement in the carrier aggregation scenario.
    [0019] To achieve the above objective, the technical solutions of the revelation are implemented as follows:
    [0020] A method for reporting measurement capability, including: a UE reports the UE's measurement capability to a base station, where the measurement capability is the capability on whether or not a measurement interval is required for the UEs perform different system and different frequency metering when the UE works in a frequency band or in a carrier aggregation scenario.

    [0027] The UE measurement capability reported by the UE is equal to an index supporting the carrier aggregation capability.
    [0028] A UE is configured to report a measurement capability of the UE to a base station, where the measurement capability is the capability on whether or not a measurement interval is required for the UE to perform different system measurement and different frequency when the UE operates in a frequency band or in a carrier aggregation scenario.

    [0030] The UE may further be configured to report a carrier aggregation capability of the UE while reporting the measurement capability of the UE to the base station.
    [0031] When the UE has an additional measurement capability, the step in which the UE reports the UE's measurement capability to the base station corresponds to: reporting together with the additional measurement capability.

    [0039] DETAILED DESCRIPTION
    [0040] The basic concept of the disclosure is that: the UE reports the measurement capability of the UE to the base station, where the measurement capability is the capability on whether or not a measurement interval is required for the UE to perform measurement from different system and different frequency when the UE works in one frequency band or in a carrier aggregation scenario. After acquiring the measurement capability of the UE, the base station determines whether or not it is necessary to configure a measurement interval for the UE according to the frequency band to which the carriers configured to be aggregated for the UE belong, the frequency band frequency to which the carrier frequency for a measurement object of a currently configured measurement task belongs, and the measurement capability of the UE.
    [0041] Fig. 3 illustrates a flowchart of a method for reporting measurement capability in disclosure modalities, as illustrated in Fig. 3, the method including:
    [0042] Step 301: A UE reports the measurement capability of the UE to a base station, where the measurement capability is the ability on whether or not a measurement interval is required for the UE to perform different system and frequency measurement different when the UE works in a frequency band or in a carrier aggregation scenario.
    [0043] In that case, the UE generally reports the UE's measurement capability to the base station according to the UE capability inquiry message sent by the base station, and of course, the UE can also report the aggregation capability of EU carriers at the same time.
    [0044] It should be noted that, in a scenario where the UE has a single receiver, at that moment, continuous carrier aggregation is supported, that is, the UE can only work in one frequency band, so that the UE reports to ability on whether or not a measurement interval is required for the UE to perform each measurement of different system and different frequency when the UE operates in a certain frequency band (a frequency band supported by the UE). In the disclosure, the different frequency includes the different frequency in an equal frequency band with the operating frequency band, and the different frequency in the different frequency band with the operating frequency band.
    [0045] In a scenario where the UE has a diversity of receivers, when the UE supports n-carrier aggregation, the carrier aggregation scenario includes a scenario in which one carrier, two carriers, three carriers, etc. are aggregated. , n-1 carriers in carriers, at that time, the UE can report the capability on whether or not a measurement interval is needed for the UE to perform each measurement of different system or different frequency when the UE works in a certain frequency band, or carriers in a diversity of frequency bands are aggregated only in a scenario in which n carriers are aggregated, the UE can also further report the capability on whether or not a measurement interval is required for the UE to perform each different system measurement and different frequency when the UE operates in a certain frequency band, or carriers in a diversity of frequency bands are aggregated in scenarios in which a po is aggregated carrier, and/or two carriers, and/or three carriers, etc., and/or n-1 carriers.
    [0046] It should be noted that if the UE has an additional measurement capability, i.e. if the UE has an independent measurement module, it reports the measurement capability together with the additional measurement capability (i.e. the measurement module capability), for example, if the measurement module supports measurement in frequency bands 1 to 7, no measurement range is required to perform measurement in frequency bands 1 to 7, if it only supports measurement in frequency band 1/3/4/5, UE reports that no measurement interval is required to perform measurement in frequency band 1/3/4/5, and a measurement interval is required to perform measurement in the 2/6/7 frequency band.
    [0047] Step 302: After acquiring the measurement capability of the UE, the base station determines whether or not it is necessary to configure a measurement interval for the UE according to the frequency band to which the configured carriers to be aggregated for belong. the UE, the frequency band to which the carrier frequency for a measurement object of a currently configured measurement task belongs, and the measurement capability of the UE.
    [0048] The disclosure further provides a compliant UE, which is configured to report the UE's metering capability to a base station, where the metering capability is the capability on whether or not a metering interval is required for the UE perform different system and different frequency measurement when the UE works in one frequency band or in a carrier aggregation scenario.
    [0049] The step in which the UE reports the measurement capability of the UE to the base station corresponds to: the UE reports according to a UE capability inquiry message sent by the base station.
    [0050] The UE is also configured to report the carrier aggregation capability of the UE while reporting the measurement capability of the UE to the base station.
    [0051] When the UE has an additional metering capability, the step where the UE reports the UE's metering capability to the base station corresponds to: reporting together with the additional metering capability.
    [0052] The implementation of the technical solutions will be further described in detail below with reference to the specific designs and modalities. Mode 1
    [0053] In embodiment 1 of the present disclosure, a flowchart of the UE reporting the measurement capability and of the base station performing the measurement setup is as illustrated in Fig. 4. In the embodiment, after cell 1, whose center frequency point in the E-UTRAN system is in F1, complete the RRC establishment process, the UE is in the connected state, F1 belongs to frequency band 1, the UE has two independent receivers, which respectively support a bandwidth of 20M, the construction of the UE is as illustrated in Fig. 2, receiver 1 supports operation in frequency band 1/2/3, receiver 2 supports operation in frequency band 1/4/5, and the following modalities are based on in the UE illustrated in Fig. 2. In that case, the UE uses receiver 1 to process data communication in cell 1 by default.
    [0054] The base station asks the UE to report the capacity information, and the UE reports the following carrier aggregation capacity information according to the capacity of the UE: supports aggregation of two carriers at most, where the first frequency band and second frequency band are not found in any specific order, and just to describe the fact of supporting carrier aggregation at frequencies in the first frequency band and second frequency band, the carrier aggregation capability reported by UE in modality 1 can be as illustrated in Table 1.1:
    Table 1.1
    [0055] The UE simultaneously reports capacity information on whether or not a measurement interval is required to perform measurement of different system and different frequency, including two parts, first, the capacity information of the UE in a scenario where the UE works in a single frequency band, as illustrated in Table 1.2:

    Table 1.2
    [0056] Since both receiver 1 and receiver 2 support operation in frequency band 1, therefore, if the UE works only in frequency band 1, the UE uses receiver 1 for processing by default (the UE can judge which receiver for processing consumes less power according to the internal implementation, if using receiver 2 consumes less power, use receiver 2 for processing by default, and likewise henceforth), as illustrated in the first row of Table 1.2 , UE works in frequency band 1 currently, no measurement range is needed to perform measurement in frequency band 1/4/5 as receiver 2 can perform different frequency measurement in frequency band 1 /4/5, a measurement range is required to perform measurement in frequency band 2/3, as receiver 2 does not support frequency band 2/3.
    [0057] Second, the UE capability information in a scenario where the UE operates in dual frequency bands is as illustrated in Table 1.3, where the serial numbers in Table 1.3 correspond to those in Table 1.1, the UE must report whether or not a measurement range is required to perform measurement of different system and different frequency in frequency bands 1 to 5 for each combination (i.e. each number), the serial numbers in Table 1.3 may not be reported and are replaced directly by two-carrier combinations to be aggregated in Table 1.1, e.g. serial number 4 is replaced by (2, 1), indicating that frequencies in frequency band 2 and frequencies in frequency band 1 can be aggregated of carriers:
    Table 1.3
    [0058] The base station configures the following measurement task for the UE via an RRC reconfiguration message according to the actual requirement, where F2 belongs to frequency band 1:MID=1, MO=F1, RC=A3MID =2, MO=F2, RC=A3
    [0059] However, according to the capability of the UE (Table 1.2), the base station determines that no measurement interval is required for the UE to perform measurement of different frequency (F2) in frequency band 1 when the UE works in frequency band 1 (F1), therefore, does not configure a measurement interval for the UE, and after receiving the configuration from the measurement task, the UE performs the measurement in the measurement task.
    [0060] Subsequently, according to the service requirement and capacity of the UE (i.e. supporting frequency band 1 and aggregation of cells of different frequency in frequency band 1), the base station configures cell 2, whose center frequency point is at F2, to be aggregated through an RRC reconfiguration message.
    [0061] In addition, according to the actual requirement, the base station further configures the following measurement task for the UE via an RRC reconfiguration message, where F3 belongs to the frequency band 4:MID=3, MO =F3, RC=A3
    [0062] However, according to the capacity of the UE (Table 1.3), the base station determines that a measurement interval is required for the UE to measure the different frequency (F3) in frequency band 4 when the UE performs aggregation on the UE. frequency band 1 (F1) and in frequency band 1 (F2), therefore, the base station still needs to configure a measurement interval for the UE via an RRC reconfiguration message (the RRC reconfiguration message can be the same RRC reset message in which MID=3 is set above), and after receiving the measurement task configuration and measurement interval, the UE performs measurement of the MID=3 measurement task at the time specified by the measurement interval.
    [0063] Subsequently, according to the actual requirement, the base station further configures the following measurement task for the UE via an RRC reconfiguration message, where F4 belongs to the frequency band 5:MID=4, MO= F4, RC=B2
    [0064] However, according to the capability of the UE (Table 1.2), the base station determines that a measurement interval is needed to measure the different frequency (F4) in frequency band 5 when the UE performs in-band aggregation frequency band 1 (F1) and in frequency band 1 (F2), but the base station has already configured a measurement interval for the UE, therefore, at that time, the base station does not need to configure a measurement interval again , and after receiving the measurement task, the UE performs the measurement of the MID=4 measurement task at the time specified by the measurement interval.
    [0065] After cell 1, whose central frequency point in the E-UTRAN system is at F1, completes the RRC establishment process, the UE is in the connected state, F1 belongs to frequency band 1, Fig. 5 illustrates a diagram of construction of the UE in embodiment 2 of the disclosure, as illustrated in Fig. 4, the UE has three separate receivers, which respectively support a bandwidth of 20M, and the UE uses the receiver 1 to process the data communication of cell 1 by default.
    [0066] The base station asks the UE to report the capacity information, and the UE reports the following carrier aggregation capacity information according to the capacity of the UE: supports aggregation of three carriers at most, where the first frequency band, second frequency band, and third frequency band are not found in any specific order, just to describe the fact that it supports carrier aggregation at frequencies in the first frequency band, second frequency band, and In the third frequency band, the three-carrier aggregation capability reported by the UE in modality 2 can be as illustrated in
    Table 2.1
    [0067] However, UE reports capacity information on whether or not a metering interval is required to perform metering of different system and different frequency, since it supports aggregation of three carriers at most, capacity information includes three-part, i.e. the capability information when the UE works on a single carrier, in a scenario where two carriers are aggregated, and in a scenario where three carriers are aggregated, where the UE capability information in a scenario where the UE works in a single frequency band (the UE uses receiver 2 for processing by default when the UE works in a single frequency band 5) can be as illustrated in Table 2.2:
    Table 2.2
    [0068] Second, the UE capacity information in a scenario where the UE works in a scenario where two carriers are aggregated corresponds to: the capacity information in Table 2.1 is based on a scenario where the UE works in a scenario in which three carriers are aggregated, the base station can know carriers of which two frequency bands can be aggregated from Table 2.1, therefore, the UE does not have to report combinations of two carriers to be aggregated when reporting capacity However, the UE needs to rearrange the carriers when reporting the metering capacity, and the UE capacity information when the UE works in dual frequency bands in mode 2 can be as illustrated in Table 2.3:

    Table 2.3
    [0069] Finally, the UE capacity information when the UE works in a what-carrier scenario is as illustrated in Table 2.4:

    Table 2.4
    [0070] The serial numbers in Table 2.4 correspond to those in Table 2.1, the UE needs to report whether or not a measurement range is required to perform different frequency measurement in frequency bands 1 to 7 for each combination, i.e. each number. It should be noted that if the UE has an additional measurement capability, i.e. if the UE has a separate measurement module, it reports according to the additional measurement capability and the measurement module capability, i.e. if the measurement module supports measurement in frequency bands 1 to 7, no measurement range is needed to perform measurement in frequency bands 1 to 7, if only support measurement in frequency band 1/3/4/5 , the UE reports that no measurement interval is required to perform measurement in frequency band 1/3/4/5, and a measurement interval is required to perform measurement in frequency band 2/6/7.
    [0071] Scenario 1: two carriers are added. According to the service requirement and the capacity of the UE, i.e. the ability to support frequency band 1 and the aggregation of cells of different frequency in frequency band 1, the base station configures a central frequency point to be aggregated in the frequency band 1. cell 2 in F2 via an RRC reset message, where F2 belongs to frequency band 1. However, the base station sets the following measurement task for the UE via the RRC reset message: MID=1, MO= F1, RC=A3MID=2, MO=F2, RC=A3 MID=3, MO=F5, RC=A3MID=4, MO=F6, RC=B2
    [0072] Where F5 belongs to frequency band 5 and F6 belongs to frequency band 6.
    [0073] According to the capability of the UE (illustrated in Table 2.3), the base station determines that no measurement interval is required for the UE to perform measurement of different frequency (F5) in frequency band 5 when the UE works in a scenario where frequency band 1 (F1) and frequency band 1 (F2) are in aggregation, and no measurement interval is required for the UE to perform different system measurement (F6) in frequency band 6, e.g. Consequently, it does not configure a measurement interval for the UE, and after receiving the configuration from the measurement task, the UE performs the measurement on the measurement task.
    [0074] Subsequently, according to the requirement, the base station further configures the following measurement task for the UE via an RRC reconfiguration message, where F3 belongs to frequency band 3, and F4 belongs to frequency band 4:MID=5, MO=F3, RC=A3MID=6, MO=F4, RC=B2
    [0075] According to the UE capability (illustrated in Table 2.3), the base station determines that a measurement interval is required for the UE to perform different frequency measurement (F3) in frequency band 3 when the UE performs the measurement. aggregation in frequency band 1 (F1) and frequency band 1 (F2), and a measurement interval is needed for the UE to perform different system measurement (F4) in frequency band 4, therefore, the base station you still need to configure a measurement interval for the UE via an RRC reconfiguration message (the RRC reconfiguration message can be the same as the RRC reconfiguration message in which MID=5/6 is configured above), and after receiving the configuration from the measurement task and the measurement interval, the UE performs the measurement on the measurement task MID=5/6 at the time specified by the measurement interval.
    [0076] Scenario 2: three carriers are added. According to the service requirement and capacity of the UE (illustrated in Table 2.1), i.e. the ability to support aggregation in frequency band 1 and different frequency cells in frequency band 1 in frequency band 5, the base station configures a center frequency point to be aggregated into cell 3 in F5 via an RRC reconfiguration message, where F5 belongs to frequency band 5. However, the base station does not add a new measurement task configuration , therefore, according to the capacity of the UE (illustrated in Table 2.4), the base station determines that a measurement interval is required for the UE to perform different frequency measurement (F3) in frequency band 3 when aggregation is performed in frequency band 1 (F1), frequency band 1 (F2) and frequency band 5, and a measurement interval is also required for the UE to perform different system measurement (F4/6) in the frequency band 4/6, per co Subsequently, the base station retains its original measurement interval setting, and after receiving the measurement task configuration, the UE performs the measurement task measurement MID=4/5/6 at the time specified by the measurement interval.
    [0077] In the modality, the UE can also report only the capability on whether or not a measurement interval is needed to perform the measurement of different system and different frequency when the UE works in a scenario where three carriers are aggregated, in relation to the ability on whether or not a measurement interval is required to perform measurement of different system and different frequency when the UE works on a single carrier and in a scenario where two carriers are aggregated, the same can be obtained from the capability of carrier aggregation (as illustrated in Table 2.1) reported by the UE, such as combinations 10 to 18 illustrated in Table 2.1, and it is indicated that if the UE works only in frequency band 1, no measurement interval is required for perform the measurement in frequency band 1/4/5/6/7, and the combination 4/5/6 indicates that if the UE performs aggregation in frequency band 1 and frequency band 4, it is not necessary ne No measurement range to perform measurement in frequency band 5/6/7.Mode 3
    [0078] After cell 1, whose central frequency point in the E-UTRAN system is at F1, completes the RRC establishment process, the UE is in the connected state, F1 belongs to frequency band 1, Fig. 6 illustrates a construction diagram of the UE in embodiment 3 of the disclosure, as illustrated in Fig. 5, and the UE has a separate receiver, which supports a bandwidth of 40M.
    [0079] The base station asks the UE to report the capacity information, and the UE reports the following carrier aggregation capacity information according to the capacity of the UE: it supports aggregation of one carrier at most, and it supports maximum bandwidth of 40MHz, the carrier aggregation information reported by the UE can be as illustrated in Table 3.1:

    Table 3.1
    [0080] However, the UE still reports the capability information on whether or not a measurement interval is required to perform different system measurement and different frequency, which can be as illustrated in Table 3.2:
    Table 3.2
    [0081] The base station configures the following measurement task for the UE via an RRC reconfiguration message according to the actual requirement, where F2 belongs to frequency band 1:MID=1, MO=F1, RC=A3MID =2, MO=F2, RC=A3
    [0082] However, according to the UE capability (Table 3.2), i.e. the capability on whether or not a measurement interval is required for the UE to perform different frequency measurement (F2) in frequency band 1 when the UE works in frequency band 1 (F1), therefore the base station still needs to configure a measurement interval for the UE via an RRC reconfiguration message (the RRC reconfiguration message can be the same as the RRC reconfiguration message in which MID=1/2 is set above), and after receiving the measurement task setting and the measurement interval, the UE performs the measurement of the MID=2 measurement task at the time specified by the measurement interval.
    [0083] Subsequently, according to the service requirement and the capacity of the UE (Table 3.1), i.e. the ability to support continuous carrier aggregation of cells of different frequency in frequency band 1, the base station configures cell 2, whose center frequency point is at F2, to be aggregated through an RRC reconfiguration message, and F1 and F2 are continuous.
    [0084] In addition, according to the requirement, the base station further configures the following measurement task for the UE via an RRC reconfiguration message, where F3 belongs to frequency band 3:MID=5, MO= F3, RC=A3
    [0085] However, according to the capacity of the UE (Table 3.2), i.e. the capacity on whether or not a measurement range is needed to perform different frequency measurement (F3) in frequency band 3 when aggregation is performed in frequency band 1 (F1) and in frequency band 1 (F2) (as F1 and F2 are continuous, the UE works in frequency band 1 at that time), since the base station has already configured an interval measurement to the UE, the base station does not need to set a measurement interval again, and after receiving the measurement task, the UE performs measurement of the MID=3 measurement task at the time specified by the measurement interval.
    [0086] The above specific forms of implementation are only preferred embodiments provided for easy understanding of the disclosure and should not be construed as limiting the disclosure. All technical remedies covered by the disclosure claims must be included within the scope of disclosure protection. INDUSTRIAL APPLICABILITY
