     Existing NR measurements do not coordinate the configurations on respective active carriers well when configuring the measurement gap. It is possible for master cell group (MCG) and secondary cell group (SCG) to be configured with different gaps through “per FR gap” (gapFR1 or gapFR2), but it is impossible to flexibly configure a gap for a certain associated carrier or a group of associated carriers.

     DETAILED DESCRIPTION 
     The technical solution of the embodiments of the present disclosure will be described below in conjunction with the drawings in the embodiments of the present disclosure, and it will be obvious that the described embodiments are only part of the embodiments of the present disclosure, but not all of them. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without making creative efforts fall within the scope of protection of the present disclosure. 
     The following is a brief description of some techniques involved in embodiments of the present disclosure. 
     1. Measurement Gap (MG) 
     In order for the user equipment (UE) to better realize the mobility handover, the network device can configure for UE to measure the reference signal receiving power (RSRP), the reference signal received quality (RSRQ) or the signal to interference plus noise ratio (SINR) of the intra-frequency, inter-frequency or different network target adjacent areas in a specific time window, and the specific time window is the measurement gap. 
     In NR Rel-15, the operating frequency range of terminal device is not only below 6 GHz, but also millimeter wave frequency range above 6 GHz. Therefore, depending on whether the terminal device has a capability to support the FR1/FR2, radio access network 4 (RAN4) defines measurement gap of UE type (per UE) and FR type (per FR), i.e. gapFR1, gapFR2 and gapUE. At the same time, UE also introduces a capability indication of independent gap (independent Gap Config) to indicate whether the measurement gap of FR1/FR2 type (per FR1/FR2) can be configured. 
     (1) GapFR1: the measurement gap configuration applies only to FR1. GapFR1 and gapUE are not supported to be configured simultaneously. In addition, in E-UTRA-NR dual connectivity (EN-DC) mode, gapFR1 does not support configuration by NR radio resource control (RRC), and only long term evolution (LTE) RRC can configure gapFR1. Here E-UTRA is the evolved-universal mobile telecommunications system (UMTS) terrestrial radio access. 
     (2) GapFR2: the measurement gap configuration applies only to FR2. GapFR2 and gapUE are not supported to be configured simultaneously. 
     (3) GapUE: the measurement gap configuration is applicable to all frequency ranges, including FR1 and FR2. In EN-DC mode, the gapUE can be configured only by LTE RRC, but cannot be configured by NR RRC. If gapUE, gapFR1, or gapFR2 are configured, the configuration cannot be performed again. 
     If the UE supports the capability of independent gap, that is, the measurements of FR1 and FR2 can be independent and unaffected, the UE can configure the measurement gap of FR type (per FR). As shown in Table 1, information about configuring a measurement gap is provided.

     2. Measurement Configuration (MeasConfig) 
     The MeasConfig includes the measurement configuration of intra-frequency measurement, inter-frequency measurement and inter-radio access technology (inter-RAT), and the configuration of the measurement gap. 
     The network applies the procedure as follows:
         to ensure that, whenever the UE has a measConfig associated with a cell group (CG), it includes a measurement object (measObject or MO) for the special cell (SpCell) and for each NR secondary cell (SCell) of the CG to be measured; here SpCell is primary cell (PCell) plus primary secondary cell (PSCell);   to configure at most one measurement identity across all CGs using a reporting configuration with the report type (reportType) set to report cell global identity (reportCGI);   when the UE is in NE-DC, NR-DC, or NR-standalone, to configure at most one measurement identity across all CGs using a reporting configuration with the reportType set to reportSFTD.       

     Here NE-DC is NR-E-UTRA dual connectivity, NR-DC is NR-dual connectivity; and SFTD is space frequency transmit diversity. 
     For the specific configuration of Measgap and MeasObject NR in RRC signaling, that is, MO addition and gap configuration, please refer to the specific measconfig IE in 3GPP protocol TS38331, which will not be repeated here. 
     3. Timing: Maximum Receive Timing Difference (MRTD) 
     A UE shall be capable of handling a relative receive timing difference between subframe timing boundary of a E-UTRA cell belonging to the master cell group (MCG) and the closest slot timing boundary of a cell belonging to secondary cell group (SCG) to be aggregated for EN-DC operation. 
     A UE shall be capable of handling a relative receive timing difference between subframe timing boundary of a E-UTRA cell belonging to the SCG to be aggregated for NE-DC operation and the closest slot timing boundary of a cell belonging to MCG. 
     A UE shall be capable of handling a relative receive timing difference between slot timing boundary of a cell belonging to MCG and the closest slot timing boundary of a cell belonging to the SCG to be aggregated for NR DC operation. A UE shall be capable of handling a relative receive timing difference among the closest slot timing boundaries of different carriers to be aggregated in NR carrier aggregation. 
     The maximum receive timing difference is described separately in the following cases. 
     (1) For E-UTRA frequency division duplex (FDD)-NR FDD intra-band EN-DC: UE indicates that it is capable of asynchronous EN-DC operation. EN-DC is E-UTRA-NR dual connectivity. 
     Maximum receive timing difference requirement for asynchronous EN-DC is shown in Table 3 below.

     In LTE R14, per component carrier (CC) MG configuration was introduced to address the ability of CA-capable UEs not in CA mode that can use spare RF chains for MG-based measurement. Currently in NR, it is not possible to configure per-CC MG and all active CCs experience a blackout period. In contrast, it is possible to configure MG for a subset of CCs. The advantages of per-CC MG configuration (i.e., better user experience, improved throughput, and increased system capacity) carry over to NR regardless of legacy or new MG patterns and are of high value to both network (NW) and UE.

Therefore, the longer interrupt influence caused by the handover/switching of the RF chain of the UE is avoided, and the transmission performance of the network device and the terminal device is improved. 
     The technical solution of the present disclosure will be further explained in the form of embodiments below.  FIG.  2    is a schematic diagram of an embodiment of a method for configuring a measurement gap in embodiments of the present disclosure, and the method includes the following operations. 
     At  201 , a network device determines configuration information of a first measurement gap, the configuration information of the first measurement gap being configuration information of a first carrier or a first frequency range. 
     Alternatively, the configuration information of the first measurement gap is configuration information of intra-frequency frequency points or inter-frequency frequency points on the first carrier; or the configuration information of the first measurement gap is configuration information of intra-frequency frequency points or inter-frequency frequency points on the first frequency range. Alternatively, the number of measurement gap pattern in the first measurement gap is one. 
     Alternatively, the configuration information of the first measurement gap is configuration information of a measurement reference signal on the first carrier, and different measurement reference signals correspond to different measurement gap patterns in the first measurement gap. Alternatively, the first measurement gap includes one or more measurement gap patterns. It can be appreciated that the number of measurement gap patterns in the first measurement gap is one or more. 
     Alternatively, the terminal device reports first indication information to the network device, the first indication information indicates that the terminal device has a first measurement indication capability, and the first indication information is used for the network device to determine the configuration information of the first measurement gap. 
     Alternatively, the first measurement indication capability includes at least one of a positioning measurement, a high-speed rail mobility measurement, or a low power consumption measurement of an Internet of Things device. It will be appreciated that the first measurement indication capability may also be referred to as the special measurement indication capability. 
     Alternatively, the positioning measurement may include Rx-Tx time difference, reference signal time difference (RSTD), or positioning reference signal-reference signal receiving power (PRS-RSRP). 
     As an example, a network device configures “Need for gap” information measured on a frequency band or carrier: 
     (1) for the intra-frequency frequency points or inter-frequency frequency points configured per carrier, the corresponding gap configuration information can keep a group of the same parameter configurations, at least including MGL, MGRP and gap pattern ID; or 
     (2) for the intra-frequency frequency points or inter-frequency frequency points configured per band, the corresponding gap configuration can keep a group of the same parameter configurations, at least including MGL, MGRP and gap pattern ID; or 
     (3) for the UE with the first measurement indication capability (for example, UE supports positioning measurement and UE supports XX measurement on band N), a new gap pattern is introduced, and its parameters are different from the existing 24 gap patterns. For example, the new gap pattern may include a longer MGL or a longer MGRP. 
     At  202 , the network device transmits the configuration information of the first measurement gap to a terminal device, the configuration information of the first measurement gap being used for the terminal device to perform a measurement. 
     The terminal device receives the configuration information of the first measurement gap from the network device. 
     At  203 , the terminal device performs a measurement according to the configuration information of the first measurement gap. 
     Alternatively, the terminal device determines the first measurement gap according to the configuration information of the first measurement gap, and performs a measurement according to the first measurement gap. 
     In the embodiment of the present disclosure, an MG configuration for a UE with a first measurement indication capability is introduced to better coordinate the MG of respective carriers/frequency ranges. Moreover, the measurement of different frequency points within the carrier/frequency range can avoid the longer interrupt effect caused by handover/switching of UE RF chain. The MG (either an existing gap pattern or a new gap pattern) can be configured for carrier/frequency range for better transmission performance of the network and terminal (e.g. better user experience, improved throughput, increased system capacity). 
       FIG.  3    is a schematic diagram of another embodiment of a method for configuring a measurement gap in embodiments of the present disclosure, and the method includes the following operations. 
     At  301 , the network device receives second indication information reported by the terminal device. 
     The second indication information is used for the network device to determine configuration information of the first measurement gap. 
     Alternatively, the second indication information indicates that the terminal device has or does not have the capability to support frequency range combination or carrier combination. Exemplarily, the UE reports that the UE has or does not have the capability to support measurement gap of frequency range combination or carrier combination. 
     At  302 , the network device determines configuration information of a first measurement gap according to the second indication information, the configuration information of the first measurement gap being configuration information of a first frequency range combination or a first carrier combination. 
     Alternatively, the first measurement gap includes one or more measurement gap patterns. 
     The network device determines the configuration information of the first measurement gap according to the second indication information, which may include but is not limited to the following implementations. 
     (1) In response to that the second indication information indicates that the terminal device has a capability to support frequency range combination or carrier combination, the network device determines the configuration information of the first measurement gap according to the second indication information. The configuration information of the first measurement gap is configuration information of a first frequency range combination or a first carrier combination, or the configuration information of the first measurement gap is configuration information of a terminal device type (per UE) or a frequency range type (per FR). 
     (2) In response to that the second indication information indicates that the terminal device does not have the capability to support frequency range combination or carrier combination, the network device determines the configuration information of the first measurement gap according to the second indication information, the configuration information of the first measurement gap being the configuration information of the terminal device type or the frequency range type. 
     Alternatively, the first carrier combination is a combination of carriers on a same frequency range (also referred to as an intra-band CA) or a combination of carriers on different frequency ranges (also referred to as an inter-band CA). 
     Alternatively, a number of the frequency range combination is one or more, or a number of the carrier combination is one or more. 
     Alternatively, the configuration information of the first measurement gap is configuration information of all carriers on different frequency ranges in the first frequency range combination. 
     Alternatively, the configuration information of the first measurement gap is configuration information of different carriers in the first carrier combination. 
     Alternatively, the configuration information of the first measurement gap is configuration information of measurement reference signals of different carriers in the first carrier combination, and different measurement reference signals correspond to different measurement gap patterns in the first measurement gap. 
     Exemplarily, according to that the UE has or does not have a capability to support the frequency range combination/carrier combination reported by the terminal device, for the UE that does not have the capability, the network device may configure the measurement gap according to the existing measurement gap of UE type (per UE) or FR type (per FR); for the UE that has the capability, the network device can configure the measurement gap per band combination, or configure the measurement gap according to the the existing gap per UE or per FR. It can be understood that the MG may be an existing MG or an MG that includes a longer MGRP. 
     Exemplarily, the network device may configure one or more MGs for the same band combination or the same carrier combination. The network device may also configure different MGs for different band combinations or different carrier combinations. 
     At  303 , the network device transmits the configuration information of the first measurement gap to the terminal device, the configuration information of the first measurement gap being used for the terminal device to perform a measurement. 
     The terminal device receives the configuration information of the first measurement gap from the network device. 
     At  304 , the terminal device performs a measurement according to the configuration information of the first measurement gap. 
     Alternatively, the terminal device determines the first measurement gap according to the configuration information of the first measurement gap, and performs a measurement according to the first measurement gap. 
     Exemplarily, in response to that the terminal device has the capability to support the frequency range combination/carrier combination and the network device has configured a measurement gap of the frequency range combination/carrier combination, the terminal device may simultaneously perform measurements according to at least one measurement gap at the measurement frequency points configured on each frequency range combination/carrier combination. 
     In the embodiment of the present disclosure, an MG configuration based on frequency range combination or carrier combination is introduced, and the design that each frequency range combination or carrier combination shares RF chain is utilized to better coordinate MG between carriers, avoid longer interruption influence caused by the handover/switching of UE RF chain, and obtain better transmission performance of the network and terminal. 
       FIG.  4    is a schematic diagram of an embodiment of a method for configuring a measurement gap in embodiments of the present disclosure, and the method includes the following operations. 
     At  401 , the network device determines configuration information of a first measurement gap. 
     Alternatively, the first measurement gap includes one or more measurement gap patterns.

     Alternatively, the configuration information of the first measurement gap is configuration information with the same MRTD in an inter-band frequency range combination. 
     Alternatively, the first measurement gap includes a plurality of measurement gap patterns with a same offset or different offsets. That is, when the number of measurement gap patterns of the first measurement gap is more, the offsets in different measurement gap patterns are the same or different. 
     Exemplarily, based on the sub-carrier spacing (SCS) of each carrier in the band of the asynchronous or synchronous DC or CA combination in the related art, at least one group of SCS combinations is supported, which corresponds to one group of downlink MRTD. In the embodiment of the present disclosure, the carrier combination of the same MRTD corresponds to the same group of MG, and the configured offset may be the same or different. For an intra-band CA, carrier combination with the same MRTD corresponds to the same group of MG, herein at least offset in the MG of each carrier configuration may be the same. For an inter-band CA, the carrier combination with the same MRTD corresponds to the same group of MG, herein at least offset in the MG of each carrier configuration may be the same. 
     At  402 , the network device transmits the configuration information of the first measurement gap to a terminal device, the configuration information of the first measurement gap being used for the terminal device to perform a measurement. 
     The terminal device receives the configuration information of the first measurement gap from the network device. 
     At  403 , the terminal device performs a measurement according to the configuration information of the first measurement gap. 
     Alternatively, the terminal device determines the first measurement gap according to the configuration information of the first measurement gap, and performs a measurement according to the first measurement gap. 
     It should be noted that the embodiment illustrated in  FIG.  4    can be combined with the embodiment illustrated in  FIG.  3   , and the combined scheme is also within the scope of protection of the present disclosure. 
     In the embodiment of the present disclosure, the MG can be configured based on time synchronization characteristic between carriers to achieve better transmission performance of the network and terminal (e.g. better user experience, improved throughput and increased system capacity). 
       FIG.  5    is a schematic diagram of an embodiment of a method for configuring a measurement gap in embodiments of the present disclosure, and the method includes the following operations. 
     At  501 , a network device determines configuration information of a first measurement gap, the configuration information of the first measurement gap being configuration information of measurement objects or measurement frequency points whose measurement reference signals are configured with a quasi-co-location (QCL) TypeD relationship. 
     Exemplarily, the network device configures the same group of MG for the measurement objects or measurement frequency points whose measurement reference signals are configured with the same QCL TypeD relationship. 
     Alternatively, the configuration information of the first measurement gap is configuration information of measurement objects or measurement frequency points of measurement reference signals associated with a same synchronization signal block. 
     Alternatively, the configuration information of the first measurement gap is configuration information of measurement objects or measurement frequency points whose measurement reference signals are associated with the same synchronization signal block (SSB) and configured with a QCL TypeD relationship. 
     Exemplarily, for a group of CSI-RS measurements associated with the same SSB, the network device may configure the same group of MG for the CSI-RS measurement objects or measurement frequency points configured with the same QCL TypeD relationship. 
     Alternatively, the first measurement gap includes one or more measurement gap patterns.

     a radio frequency (RF) circuit  910 , a memory  920 , an input unit  930 , a display unit  940 , a sensor  950 , an audio circuit  960 , and a wireless fidelity (WiFi) module  970 , a processor  980 , and a power supply  990  when taking the terminal device as a mobile phone as an example. The RF circuit  910  includes a receiver  914  and a transmitter  912 . Those skilled in the art will appreciate that the structure of the mobile phone illustrated in  FIG.  9    does not constitute a limitation on the mobile phone and may include more or fewer parts than illustrated, or a combination of parts, or a different arrangement of parts. 
     The following is a detailed introduction to each component of the mobile phone with reference to  FIG.  9   . 
     The RF circuit  910  can be used for receiving and transmitting signals during sending and receiving information or talking. Specifically, the RF circuit  910  receives downlink information of the base station and then transmits it to the processor  980  to process. In addition, the RF circuit  910  transmits the designed uplink data to the base station. Generally, the RF circuit  910  includes but is not limited to antennas, at least one amplifier, transceivers, couplers, low noise amplifiers (LNA), duplexer, etc. In addition, the RF circuit  910  may also communicate with a network and other devices through wireless communication. The wireless communication may use any communication standard or protocol, including but not limited to the global system of mobile communication (GSM), general packet radio service (GPRS), code division multiple access (CDMA), wideband code division multiple access (WCDMA), long term evolution (LTE), E-mail, short messaging service (SMS), etc. 
     The memory  920  may be used to store software programs and modules, and the processor  980  implements various functional applications and data processing of the mobile phone by running the software programs and modules stored in the memory  920 . The memory  920  may mainly include a storage program area and a storage data area. The storage program area may store an operating system, an application program required for at least one function (such as a sound playback function, an image playback function or the like) and the like. The storage data area may store data (such as audio data, phone book, etc.) created according to the use of the mobile phone. Additionally, the memory  920  may include high-speed random access memory and may also include non-volatile memory, such as at least one disk storage device, flash memory device or other volatile solid-state storage device. 
     The input unit  930  is used to receive inputted numeric or character information and to generate key signal input related to user settings and function control of the mobile phone. Specifically, the input unit  930  may include a touch panel  931  and other input devices  932 . The touch panel  931 , also referred to as a touch screen, may collect touch operations on or near the touch panel  931  by a user (such as operations on or near the touch panel  931  by a user using any suitable object or accessory such as a finger, stylus, etc.) and drive corresponding connection devices according to a preset program. Alternatively, the touch panel  931  may include two parts of a touch detection device and a touch controller. The touch detection device detects the touch orientation of the user, detects the signal brought by the touch operation, and transmits the signal to the touch controller. The touch controller receives touch information from the touch detection device, converts it into contact coordinates, sends it to the processor  980 , and can receive and execute commands from the processor  980 . In addition, the touch panel  931  may be implemented in various types such as resistive, capacitive, infrared and surface acoustic waves. The input unit  930  may include other input devices  932  in addition to the touch panel  931 . Specifically, other input devices  932  may include but are not limited to one or more of a physical keyboard, function keys (such as volume control keys, switch keys etc.), trackball, mouse, joystick, etc. 
     The display unit  940  may be used to display information input by or provided to the user and various menus of the mobile phone. The display unit  940  may include a display panel  941 , which may optionally be configured in the form of a liquid crystal display (LCD), an organic light-emitting diode (OLED) or the like. Further, the touch panel  931  may overlay the display panel  941 , and when the touch panel  931  detects a touch operation on or near it, the touch operation is transmitted to the processor  980  to determine a type of touch event, and then the processor  980  provides a corresponding visual output on the display panel  941  according to the type of touch event. Although in  FIG.  9   , the touch panel  931  and the display panel  941  are two independent components to implement the input and output functions of the mobile phone, but in some embodiments, the touch panel  931  and the display panel  941  may be integrated to implement the input and output functions of the mobile phone. 
     The mobile phone may also include at least one sensor  950 , such as a light sensor, a motion sensor and other sensors. Specifically, the light sensor may include an ambient light sensor that can adjust the brightness of the display panel  941  according to the brightness of the ambient light and a proximity sensor that can turn off the display panel  941  and/or the backlight when the mobile phone moves to the ear. As a kind of motion sensor, the accelerometer sensor can detect the acceleration in all directions (usually three axes), and can detect the magnitude and direction of gravity when it is still. It can be used to the application of identifying mobile phone attitude (such as horizontal and vertical screen switching, related games, magnetometer attitude calibration), vibration recognition related functions (such as pedometer, knocking), etc. As for gyroscopes, barometers, hygrometers, thermometers, infrared sensors and other sensors that can be configured in mobile phones, they will not be repeated here. 
     The audio circuit  960 , the loudspeaker  961  and the microphone  962  may provide an audio interface between the user and the mobile phone. The audio circuit  960  can transmit the received electrical signal converted by audio data to the loudspeaker  961 , and the loudspeaker  961  converts it into a sound signal for output. On the other hand, the microphone  962  converts the collected sound signal into an electrical signal, which is received by the audio circuit  960  and converts into audio data, and then outputs the audio data to the processor  980  for processing, and then transmits the audio data to, for example, another mobile phone via the RF circuit  910 , or outputs the audio data to the memory  920  for further processing. 
     WiFi is a short-distance wireless transmission technology. Mobile phones can help users send and receive e-mails, browse web pages and access streaming media through WiFi module  970 , which provides users with wireless broadband internet access. Although the WiFi module  970  is illustrated in  FIG.  9   , it is understood that it is not an essential component of a mobile phone and may be omitted as necessary without changing the essence of the present disclosure. 
     The processor  980  is a control center of the mobile phone, the processor connects various parts of the whole mobile phone by various interfaces and lines, executes various functions of the mobile phone and processes data by running or executing software programs and/or modules stored in the memory  920 , and calls data stored in the memory  920 , thereby monitoring the mobile phone as a whole. Alternatively, the processor  980  may include one or more processing units. For example, the processor  980  may integrate an application processor and a modem processor. The application processor primarily handles operating systems, user interfaces, applications, and the like. The modem processor primarily handles wireless communications. It will be appreciated that the modem processor described above may also not be integrated into the processor  980 . 
     The mobile phone also includes a power supply  990  (such as a battery) for supplying power to the various components. For example, the power supply may be logically connected to the processor  980  through a power management system, thereby realizing functions such as managing charging, discharging, and power consumption management through the power management system. Although not illustrated, the mobile phone may also include a camera, a Bluetooth module, etc., which will not be repeated here.
