[0023] The technical solution in this application will be described below with reference to the accompanying drawings.

[0024] Figure 1 illustrates a wireless communication system 100 used in an embodiment of the present application. The wireless communication system 100 may include a network device 110 and a terminal device 120. The network device 110 may be a device that communicates with the terminal device 120. The network device 110 may provide communication coverage for a specific geographic area and may communicate with the terminal device 120 within the coverage area.

[0025] FIG1 exemplarily shows a network device and two terminals. Optionally, the wireless communication system 100 may include multiple network devices and each network device may include other numbers of terminal devices within its coverage area, which is not limited in the embodiments of the present application.

[0026] Optionally, the wireless communication system 100 may further include other network entities such as a network controller and a mobility management entity, which is not limited in the embodiment of the present application.

[0027] It should be understood that the technical solutions of the embodiments of the present application can be applied to various communication systems, such as: fifth generation (5G) system or new radio (NR), long term evolution (LTE) system, LTE frequency division duplex (FDD) system, LTE time division duplex (TDD), etc. The technical solutions provided in this application can also be applied to future communication systems, such as the sixth generation mobile communication system, satellite communication system, etc.

[0028] The terminal device in the embodiments of the present application may also be referred to as user equipment (UE), access terminal, user unit, user station, mobile station, mobile station (MS), mobile terminal (MT), remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent or user device. The terminal device in the embodiments of the present application may refer to a device that provides voice and / or data connectivity to a user and can be used to connect people, objects and machines, such as a handheld device with wireless connection function, a vehicle-mounted device, etc. The terminal device in the embodiments of the present application can be a mobile phone, a tablet computer, a laptop computer, a PDA, a mobile internet device (MID), a wearable device, a virtual reality (VR) device, an augmented reality (AR) device, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical surgery, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, a wireless terminal in a smart home, etc. Optionally, the UE can be used to act as a base station. For example, the UE can act as a scheduling entity that provides sidelink signals between UEs in vehicle-to-everything (V2X) or device-to-device (D2D). For example, a cellular phone and a car communicate with each other using sidelink signals. The cellular phone and smart home devices communicate without relaying the communication signal through a base station.

[0029] The network device in the embodiments of the present application may be a device for communicating with a terminal device, and may also be referred to as an access network device or a radio access network device. For example, the network device may be a base station. The network device in the embodiments of the present application may refer to a radio access network (RAN) node (or device) that connects a terminal device to a wireless network. A base station may broadly cover various names as follows, or be replaced with the following names, such as: NodeB, evolved NodeB (eNB), next generation NodeB (gNB), relay station, access point, transmitting and receiving point (TRP), transmitting point (TP), master eNB (MeNB), secondary eNB (SeNB), multi-standard radio (MSR) node, home base station, network controller, access node, wireless node, access point (AP), transmission node, transceiver node, baseband unit (BBU), remote radio unit (RRU), active antenna unit (AAU), remote radio head (RRH), central unit (CU), distributed unit (DU), positioning node, etc. A base station may be a macro base station, a micro base station, a relay node, a donor node, or the like, or a combination thereof. A base station may also refer to a communication module, modem, or chip used to be set in the aforementioned device or apparatus. A base station may also be a mobile switching center and a device that performs base station functions in D2D, V2X, and machine-to-machine (M2M) communications, a network-side device in a 6G network, or a device that performs base station functions in future communication systems. A base station may support networks with the same or different access technologies. The embodiments of this application do not limit the specific technology and specific device form adopted by the network equipment.

[0030] Base stations can be fixed or mobile. For example, a helicopter or drone can be configured to act as a mobile base station, and one or more cells can move based on the location of the mobile base station. In other examples, a helicopter or drone can be configured to act as a device that communicates with another base station.

[0031] In some deployments, the network device in the embodiments of the present application may refer to a CU or a DU, or the network device includes a CU and a DU. The gNB may also include an AAU.

[0032] The network equipment and terminal devices can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; they can also be deployed in the air on aircraft, balloons, and satellites. The embodiments of this application do not limit the scenarios in which the network equipment and terminal devices are located.

[0033] It should be understood that all or part of the functions of the communication device in this application can also be implemented through software functions running on hardware, or through virtualization functions instantiated on a platform (such as a cloud platform).

[0034] The terminal device can perform measurements on neighboring cells (for example, radio resource management (RRM) measurements). The measurements can be performed based on a measurement interval. The measurement interval may refer to a certain time interval required for the terminal device to perform the measurement. During this time interval, the terminal device may suspend all or part of the service cells. When the service cell is suspended, the terminal device may suspend the downlink reception of the service cell and receive the downlink signal of the neighboring cell, thereby achieving the purpose of receiving the downlink reference signal of the neighboring cell. In some embodiments, when multiple service cells of the terminal device operate in different frequency ranges, the terminal device may need to suspend all service cells or suspend service cells within a frequency range within the measurement interval.

[0035] Whether a measurement gap is required for measurement depends primarily on the hardware capabilities of the terminal device and the difference between the frequency of the neighboring cell and the frequency of the terminal device's current serving cell. For example, when the number of serving cells of a terminal device is relatively small and / or the frequency range of the serving cells is relatively small, the terminal device is more likely to have sufficient hardware to measure neighboring cells, meaning that it is more likely that a measurement gap is not required. Conversely, the terminal device is more likely to require a measurement gap.

[0036] From this, it can be seen that for different terminal devices, for the same neighboring cell, some terminal devices require measurement intervals for measurement, while some terminal devices do not. Alternatively, for the same terminal device, for the same neighboring cell, when the current serving cell is different, measurement intervals may be required for measurement of the neighboring cell, or measurement intervals may not be required for measurement of the neighboring cell. Alternatively, for the same terminal device, whether measurement intervals are required for measurement for different neighboring cells may also vary.

[0037] In response to the above situation, the network device may ask the terminal device whether a measurement interval is required when measuring certain frequency bands. For example, the network device may inquire about this in a downlink message. The downlink message may, for example, include a radio resource control (RRC) reconfiguration (RRCReconfiguration) message and / or an RRC recovery (RRCResume) message. In response to the network device's inquiry, the terminal device may feedback whether a measurement interval is required for a certain cell or a certain frequency band. For example, the terminal device may report in an uplink message whether a measurement interval is required for a certain cell or a certain frequency band. The uplink message may, for example, include an RRC reconfiguration complete (RRCReconfigurationComplete) message or an RRC recovery complete (RRCResumeComplete) message.

[0038] In some communication system architectures (for example, an architecture without stand alone or a 4G-5G dual connectivity (EUTRA-NR dual connectivity, ENDC) architecture), the information reported by the terminal device may include, for example: an indication that a normal measurement interval is required (for example, which can be represented by a gap), an indication that a network controlled short measurement interval (network controlled small gap, NCSG) is required (for example, which can be represented by ncsg), or an indication that neither a normal measurement interval nor NCSG is required (for example, which can be represented by nongap-noncsg).

[0039] During some measurements, the terminal device needs to suspend the serving cells within all frequency ranges, and such a measurement gap can be called a measurement gap configured by the terminal device (per UE measurement gap). During some measurements, the terminal device needs to suspend the serving cells within a certain frequency range, and such a measurement gap can be called a measurement gap configured by frequency range (per frequency range measurement gap). For the measurement gap configured by frequency range, when the frequency range of the measurement interval configured by frequency range is the first frequency range (that is, the measurement gap for the first frequency range is configured), the terminal device needs to suspend the serving cells within the first frequency range in the measurement gap.

[0040] It should be noted that when configuring the measurement interval for the first frequency range, the terminal device only needs to suspend the service cell in the first frequency range, and the service cells in other frequency ranges are not affected, that is, the terminal device can normally receive the downlink signals of the service cells in other frequency ranges.

[0041] In some embodiments, the frequency range (FR) of the measurement interval configured by frequency range may include frequency range 1 (FR1) or frequency range 2 (FR2). The frequency range of frequency range 1 may include, for example, 410MHz to 7125MHz. The frequency range of frequency range 2 may include, for example, 24250MHz to 71GHz. When the measurement interval for FR1 is configured, the terminal device may only suspend the service cell operating in FR1, and the service cell in FR2 may not be affected. Alternatively, when the measurement interval for FR2 is configured, the terminal device may only suspend the service cell operating in FR12, and the service cell in FR1 may not be affected.

[0042] The terminal capability information of the terminal device may include whether the terminal device supports the measurement interval configured by frequency range. For example, the terminal capability information may include the parameter independentGapConfig to indicate whether the terminal device supports the measurement interval configured by frequency range. It should be noted that the parameter independentGapConfig can only be configured to support the measurement interval configured by frequency range when all frequency band combinations of the terminal device support the measurement interval configured by frequency range. That is, the parameter independentGapConfig is indicated according to the granularity of the terminal device. In other words, based on the indication of the parameter independentGapConfig, the information obtained by the network device is: the terminal device either supports the measurement interval configured by frequency range on all frequency band combinations, or does not support the measurement interval configured by frequency range on all frequency band combinations.

[0043] Based on the terminal capability information, the network device can configure the terminal device to perform measurements according to the terminal device configured measurement interval or the frequency range configured measurement interval. For example, if the parameter independentGapConfig indicates that the terminal device supports the frequency range configured measurement interval, the network device can configure the terminal device to perform measurements according to the frequency range configured measurement interval.

[0044] In some cases, the difficulty for terminal devices to support measurement gaps configured by frequency range varies across different frequency band combinations, making it difficult to pass testing for all frequency band combinations. Therefore, if the parameter independentGapConfig in the terminal capability information indicates whether the terminal device supports measurement gaps configured by frequency range, it will be difficult for the terminal device to support measurement gaps configured by frequency range. In view of this, operators were unable to deploy this technical feature for a long time.

[0045] In response to the above situation, the 3rd Generation Partnership Project (3GPP) has proposed the following three solutions. Although these three technical solutions can solve the above problems to a certain extent, some problems still exist.

[0046] Solution 1, proposed in proposal RP-222276, introduces measurement capability information within the terminal capability information, based on the granularity of the frequency band combination, to indicate the measurement intervals configured by frequency range. This newly introduced measurement capability information indicates whether the terminal device supports the measurement intervals configured by frequency range across all frequency bands in the frequency band combination.

[0047] For solution one, when the terminal device reports that a certain frequency band combination does not support the measurement interval configured by frequency range, in the rules of some protocols, all fallback band combinations of the frequency band combination also do not support the measurement interval configured by frequency range. However, since the fallback band combination is a subset of the frequency band combination, when the frequency band combination does not support the measurement interval configured by frequency range, the fallback band combination may support the measurement interval configured by frequency range. Therefore, the terminal device needs to separately report the support status of these fallback band combinations for the measurement interval configured by frequency range. This will result in a large signaling overhead.

[0048] Solution 2 was proposed in proposal RP-221702. Solution 2 proposes that the terminal device can report a carrier number threshold N. Wherein, N can be an integer greater than or equal to 0. When the number of carriers in the frequency band combination is greater than or equal to N, the terminal device may not support the measurement capability of the measurement interval configured by frequency range. When the number of carriers in the frequency band combination is less than N, the terminal device can report whether it supports the measurement capability of the measurement interval configured by frequency range according to the granularity of the frequency band combination. In other words, when the number of carriers in the frequency band combination is less than N, the method in Solution 1 can be used.

[0049] For solution 2, for frequency band combinations with a number of carriers greater than or equal to N, no additional signaling is required to indicate whether the measurement interval configured by frequency range is supported. For example, when N=3, all frequency band combinations with a number of carriers greater than or equal to 3 do not require additional signaling to indicate whether the measurement interval configured by frequency range is supported (except for the indication signaling of parameter N). Therefore, solution 2 can reduce signaling overhead to a certain extent. However, for frequency band combinations with a number of carriers less than N, solution 2 is similar to solution 1 and has the problem of large signaling overhead.

[0050] Solution 3, proposed in proposal RP-222366, categorizes band combinations as either difficult or easy. For difficult band combinations, the terminal device's measurement capability is indicated at the band combination granularity. That is, for difficult band combinations, the method described in Solution 1 can be used. For easy band combinations, a single bit can be used to indicate whether all easy band combinations support the measurement capability of the measurement interval configured by frequency range.

[0051] For solution three, it is difficult to distinguish between difficult frequency band combinations and easy frequency band combinations. If the signaling is marked as to whether it is a difficult frequency band combination, the signaling overhead will also increase, and the increased signaling overhead may be equivalent to the signaling overhead increased by solution one. If the signaling is not marked as to whether it is a difficult frequency band combination, there may also be compatibility issues for different terminal devices. For example, for terminal devices that were launched earlier, some frequency band combinations are difficult. For terminal devices that were launched later, the terminal's capabilities have been enhanced, and the originally difficult frequency band combinations may no longer be difficult. Therefore, solution three cannot be compatible with the above-mentioned terminal devices with different launch times. In addition, although solution three can reduce signaling overhead to a certain extent, for difficult frequency band combinations, there is still a problem of high signaling overhead similar to solution one.

[0052] As can be seen, related technologies can indicate whether a terminal device supports configuration of measurement intervals by frequency range through terminal device capability information. However, the above solutions all have several issues. When the granularity of the indication is coarse, it is difficult to indicate when some frequency bands support configuration of measurement intervals by frequency range. When the granularity of the indication is fine, there will be problems such as high signaling overhead or compatibility issues.

[0053] Figure 2 is a schematic flow chart of a communication method provided in an embodiment of the present application. The method shown in Figure 2 can be performed by a terminal device and / or a network device. The method shown in Figure 2 can include steps S210 and S220.

[0054] In step S210, the terminal device receives the first inquiry information. Accordingly, the network device may send the first inquiry information.

[0055] Step S220: In response to the first query information, the terminal device sends first indication information. Correspondingly, the network device receives the first indication information.

[0056] The first inquiry information may be used to inquire about information related to the measurement interval. This application does not limit the specific content of the information related to the measurement interval. For example, the information related to the measurement interval may include one or more of the following information: frequency band combination information associated with the measurement interval, frequency band information associated with the measurement interval, information on whether a measurement interval is required, information on whether support for configuring the measurement interval by frequency range is required, etc.

[0057] The first indication information may be used to indicate whether the terminal device supports configuration of measurement intervals by frequency range. For example, the first indication information may indicate that some frequency bands of the terminal device support configuration of measurement intervals by frequency range; and / or, the first indication information may indicate that some frequency bands of the terminal device do not support configuration of measurement intervals by frequency range. In other words, the first indication information may be used to indicate whether the terminal device supports configuration of measurement intervals by frequency range on all or some frequency bands.

[0058] The first indication information is a response to the first query information. In other words, in response to the first query information, the terminal device may send the first indication information. In some embodiments, the frequency band combination indicated by the first indication information may be determined based on the first query information. For example, when the first query information is used to query the target for information related to the measurement interval, the first indication information may be used to indicate whether the measurement of the target frequency band supports the measurement interval configured by frequency range.

[0059] It should be noted that this application does not limit the granularity of the indication of the first indication information. For example, the granularity of the indication may include frequency band, frequency, cell, frequency band combination, subset of frequency band combination, terminal device, etc. For example, the first indication information may indicate whether the terminal device supports measurement intervals configured by frequency range on a certain frequency band. Alternatively, the first indication information may indicate whether one or more cells on a certain frequency support measurement intervals measured by frequency range. Alternatively, the first indication information may indicate whether the terminal device supports measurement intervals measured by frequency range in a certain cell. Alternatively, the first indication information may indicate whether the terminal device supports measurement intervals configured by frequency range on all frequency band combinations. Alternatively, the first indication information may indicate whether the terminal device supports measurement intervals configured by frequency range on a certain frequency band combination. The frequency band combination may include one or more frequency bands. Alternatively, the first indication information may indicate whether the terminal device supports measurement intervals configured by frequency range on a subset of a certain frequency band combination. The number of frequency bands included in the subset of a frequency band combination may be less than or equal to the number of frequency bands included in the frequency band combination.

[0060] It should be noted that the granularity of the query of the first query information may be the same as or different from the granularity of the indication of the first indication information. For example, the granularity of the query of the first query information may be greater than or equal to the granularity of the indication of the first indication information. As an implementation method, the first query information may query information related to the measurement interval with the frequency band as the granularity, and the first indication information may indicate whether the measurement interval configured by frequency range is supported with the cell as the granularity. Alternatively, the first query information may query information related to the measurement interval with the frequency band combination as the granularity, and the first indication information may indicate whether the measurement interval configured by frequency range is supported with the frequency band as the granularity.

[0061] Based on the present application, the terminal device can report whether it supports the information of configuring the measurement interval by frequency range by responding to the first inquiry information. Therefore, the terminal device can report the support status of the measurement interval configured by frequency range at an appropriate granularity. On the one hand, the technical solution of the present application can report that some frequency bands support the measurement interval configured by frequency range. On the other hand, compared with the reporting according to the granularity of the terminal device or the granularity of the frequency band combination, the present application can report whether the measurement interval configured by frequency range is supported according to the granularity of the fallback frequency band combination, thereby saving signaling overhead. In addition, the method can be executed by a terminal device with any capability, that is, the method has good compatibility.

[0062] This application does not limit the message that carries the first indication information. For example, the first indication information may be included in an RRC Reconfiguration Complete message or an RRC Recovery Complete message. This application also does not limit the message that carries the first inquiry information. The first inquiry information may be included in an RRC Reconfiguration message or an RRC Recovery message.

[0063] As an implementation method, the first inquiry information may be information already available in the relevant technology, and the terminal device may feedback the first indication information in response to the information already available in the relevant technology. For example, the first inquiry information may be the information described above for inquiring whether a measurement interval is required when the terminal device performs measurement. That is, the information for inquiring whether a measurement interval is required when the terminal device performs measurement can be used to trigger the sending of the first indication information. The terminal device can not only report whether a measurement interval is required based on the first inquiry information, but also report whether support for configuring the measurement interval by frequency range is required. It can be understood that this can reduce the information interaction between the network device and the terminal device and improve communication efficiency.

[0064] As an implementation, the first inquiry information may include one or more frequency bands. The one or more frequency bands may constitute a complete frequency band combination, or the one or more frequency bands may be a subset of the frequency band combination (ie, a fallback frequency band combination of the frequency band combination).

[0065] The one or more frequency bands may include a target frequency band. For example, the first query information may be used to query the terminal device whether a measurement interval is required when measuring the target frequency band. Based on the first query information, the network device may request the terminal device to report whether a measurement interval is required for the target frequency band. Furthermore, based on the first query information, the terminal device may send first indication information indicating whether the target frequency band supports configuration of a measurement interval by frequency range. The one or more frequency bands may be represented by a list.

[0066] It should be noted that the target frequency band may be the same frequency band as the RAT of the serving cell of the terminal device, and / or a frequency band different from the RAT of the serving cell.

[0067] In some embodiments, the first indication information may be related to the first measurement. For example, the first indication information may be used to indicate whether the terminal device supports configuring the measurement interval of the first measurement by frequency range. The first measurement may be, for example, a measurement of a cell or a frequency band.

[0068] In some embodiments, when the first measurement includes intra-frequency measurement (intra-frequency measurement), the first indication information can be used to indicate whether the cell associated with the serving cell of the terminal device needs to configure the measurement interval according to the frequency range. The target cell of the intra-frequency measurement can be on the same carrier frequency as the serving cell of the terminal device, that is, on the same center frequency. Therefore, the intra-frequency measurement can also be called the same-frequency measurement. The cell associated with the serving cell can be the target cell of the above-mentioned intra-frequency measurement.

[0069] In some implementations, when the first measurement includes intra-frequency measurement, the first indication information may be used to indicate whether the serving cell needs to configure the measurement interval according to the frequency range. Since the first measurement includes intra-frequency measurement, the cell associated with the serving cell may be co-frequency with the serving cell. Therefore, when the terminal device reports whether the serving cell needs to configure the measurement interval according to the frequency range according to the serving cell, it is equivalent to the terminal device reporting whether the cell associated with the serving cell needs to configure the measurement interval according to the frequency range.

[0070] In some embodiments, when the first measurement includes an inter-frequency measurement, the first indication information is used to indicate whether a measurement interval is required for the frequency band associated with the first measurement, per frequency range. The frequency band associated with the first measurement may, for example, be a target frequency band for the first measurement. As an implementation, the target frequency band may be determined via the first query information. For example, the first query information may be used to inquire whether a measurement interval is required when measuring the target frequency band, where the target frequency band may be the frequency band associated with the first measurement.

[0071] It should be noted that inter-frequency measurements may include inter-frequency measurements of the same radio access technology (RAT) and inter-frequency measurements of different radio access technologies (inter-RAT measurements). That is, the frequency band associated with the first measurement may include: a frequency band that is the same as the radio access technology of the serving cell, and / or a frequency band that is different from the radio access technology of the serving cell.

[0072] In some embodiments, the first indication information may also be used to indicate the frequency range for which the measurement interval is to be configured when the measurement interval needs to be configured by frequency range. The frequency range includes the first frequency range and / or the second frequency range. It will be understood that the first indication information may not only be used to indicate whether the measurement interval needs to be configured by frequency range, but may also, when the measurement interval needs to be indicated by frequency range, further indicate which frequency range the measurement interval is to be configured for. The network device may directly configure the measurement interval for a certain frequency range based on the first indication information.

[0073] As an implementation, the first frequency range may be, for example, frequency range 1 (FR1), and the second frequency range may be, for example, frequency range 2 (FR2). The frequency range of frequency range 1 may, for example, include 410 MHz to 7125 MHz. The frequency range of frequency range 2 may, for example, include 24250 MHz to 71 GHz.

[0074] It should be noted that, when the frequency targeted by the measurement interval is the first frequency range, the terminal device needs to suspend the serving cell within the first frequency range when performing the measurement, while the communication of the serving cell outside the first frequency range may not be affected. When the frequency range includes the first frequency range and the second frequency range, the terminal device may suspend either or both of the first frequency range and the second frequency range during the measurement.

[0075] The terminal device may send the first indication information when the first condition is met. The first condition may include, for example, that a measurement interval is required when the terminal device performs measurement. That is, when a measurement interval is required when the terminal device performs measurement, the terminal device may send the first indication information. Taking the example of the terminal device being able to report "normal measurement interval required" (gap), "NCSG required" (ncsg), or "neither normal measurement interval nor NCSG required" (nongap-noncsg), the terminal device will send the first indication information only when the terminal device reports gap or ncsg.

[0076] The method provided by the present application is described in detail below through Example 1 and Example 2. It should be noted that Example 1 and Example 2 can be implemented separately or in combination.

[0077] Example 1

[0078] Figure 3 is a schematic flow chart of a communication method provided in Example 1. The method shown in Figure 3 may include steps S310 to S330. The method shown in Figure 3 may be executed by a terminal device and a network device.

[0079] Step S310: The network device sends a first query message. The terminal device receives the first query message. The first query message may be used to inquire whether a measurement interval is required for measurement of a frequency band list. The frequency band list may include a target frequency band.

[0080] In other words, based on the first query information, the network device may require the terminal device to report whether the measurement of the frequency bands in the frequency band list requires a measurement interval. The first query information may be carried in an RRCReconfiguration message or an RRCResume message.

[0081] Step S320: The terminal device sends first indication information. The network device receives the first indication information. The first indication information is used to indicate whether the measurement interval for the frequency band list needs to be configured according to the frequency band range.

[0082] When a measurement interval is required and the measurement interval needs to be configured according to the frequency band range, the response message to the first inquiry information may include the first indication information. The response message to the first inquiry information may be, for example, an RRCReconfigurationComplete message or an RRCResumeComplete message.

[0083] For intra-frequency measurements, the terminal device can report whether the measurement interval needs to be configured by frequency range according to each serving cell. For inter-frequency measurements, the terminal device can report whether the measurement interval needs to be configured by frequency range according to each frequency band.

[0084] Step S330: The network device configures a measurement interval for the terminal device according to the first indication information.

[0085] The network device may configure the measurement interval according to the FR1 frequency range and / or the FR2 frequency range according to the measurement interval requirement indicated by the first indication information. That is, the network device may require the terminal device to perform RRM measurements of neighboring cells according to the measurement interval configured in FR1 and / or the measurement interval configured in FR2.

[0086] Example 2

[0087] Figure 4 is a schematic flow chart of a communication method provided in Example 1. The method shown in Figure 4 may include steps S410 to S430. The method shown in Figure 4 may be executed by a terminal device and a network device.

[0088] Step S410: The network device sends a first inquiry message. The terminal device receives the first inquiry message. The first inquiry message is used to inquire whether a measurement interval is required for measuring a frequency band in the frequency band list.

[0089] Step S420: The terminal device sends first indication information. The network device receives the first indication information. The first indication information is used to indicate whether the measurement interval of the frequency bands in the frequency band list needs to be configured according to the FR1 and / or FR2 frequency band range.

[0090] It is understandable that, when the terminal device reports whether the first measurement needs to be configured according to the frequency range, the terminal device may further report the measurement interval that needs to be configured according to the FR1 and / or FR2 frequency range.

[0091] For intra-frequency measurements, the terminal device can report on a per-serving-cell basis whether it needs to configure a measurement gap per FR1 frequency range (per FR1 gap), per FR2 frequency range (per FR2 gap), or both (per FR gap). For inter-frequency measurements, the terminal device can report on a per-FR1 gap, per-FR2 gap, or per-FR gap basis for each frequency band.

[0092] Step S430: Based on step S420, the network device configures a measurement interval for the terminal device according to the first indication information.

[0093] It is understandable that, when the terminal device reports a measurement interval that needs to be configured according to the FR1 and / or FR2 frequency range, the network device can be more targeted when configuring the specific measurement interval based on the reported content.
