Abstract

The method comprises the steps that network equipment generates measurement configuration information according to a subcarrier spacing SCS and sends the measurement configuration information to a terminal, wherein the measurement configuration information is used for configuring a measurement interval parameter and the time length of a synchronous signal measurement window; and the terminal determines the time information of the measurement interval according to the measurement interval parameters and the time length of the synchronization signal measurement window, and measures the reference signal to be measured according to the time information of the measurement interval. Since the network device can configure the measurement interval according to the subcarrier interval, in an application scenario of a large subcarrier interval, the network device can configure a smaller measurement interval, thereby reducing resource overhead of measurement.

Description

Measurement configuration method and communication device

Technical Field

The present application relates to the field of communications technologies, and in particular, to a measurement configuration method and a communications apparatus.

Background

Due to the mobility of the terminal, the terminal may move from the coverage of one cell to the coverage of another cell, and in order to ensure the service continuity and the communication quality of the terminal, the terminal may perform cell reselection (reselection) or cell handover (handover). Both cell reselection and cell handover require the terminal to perform cell measurement, that is, the terminal performs Radio Resource Management (RRM) measurement.

The network device may use a Synchronization Signal Block (SSB) or a channel state information reference signal (CSI-RS) for neighbor cell measurements. Referring to fig. 1, in the process of measuring the neighboring cell, the terminal needs to switch from the current cell to a frequency point where a cell (also referred to as a neighboring cell or a neighboring cell) neighboring the current cell is located. For example, the terminal operates on cell 1 with frequency point f1 to receive data, during the process of cell measurement, the terminal needs to switch to the frequency point to measure on cell 2 of f2, and after the terminal completes the measurement, the terminal needs to return to f1 from frequency point f2, that is, to switch from cell 2 to cell 1. The time required for the terminal to complete the entire cell measurement process is called a measurement interval (gap), i.e., the sum of the time for the terminal to switch from cell 1 to cell 2, the time for the terminal to make cell measurements, and the time for the terminal to switch from cell 2 to cell 1.

The time of cell measurement is generally the duration of an SS block based RRM measurement timing configuration (SMTC) based on a Synchronization Signal (SS) block. As the subcarrier width of the data increases, the duration length of the SSB decreases, for example, the subcarrier width of the data is 240KHz, the duration of the SSB is 2.25ms, the subcarrier width of the data is 480KHz, and the duration of the SSB is 1.125 ms. A New Radio (NR) system of the fifth generation mobile communication technology (5G) is applicable to a carrier frequency band greater than or equal to 52.6GHz, and supports a larger subcarrier spacing due to a higher carrier frequency, for example, supportable subcarrier widths include 240KHz, 480KHz, 960KHz, 1920KHz, 3840 KHz. In this case, if the gap configured below 120KHz is used, it is apparent that the measurement time is long, resulting in a waste of resources.

Disclosure of Invention

The embodiment of the application provides a measurement configuration method and a communication device, and provides smaller gap configuration in an application scene with a large subcarrier interval so as to save resources as much as possible.

In a first aspect, a measurement configuration method is provided, where the method of the first aspect may be performed by a first apparatus, which may be a communication device or a communication apparatus capable of supporting a communication device to implement a function required by the method, such as a system-on-chip. Illustratively, the communication device may be a network device. The method comprises the following steps: the network equipment generates measurement configuration information according to the subcarrier spacing SCS and sends the measurement configuration information to the terminal; the measurement configuration information is used for configuring a measurement interval parameter and a time length of a synchronization signal measurement window, the measurement interval parameter is used for a terminal to measure a reference signal to be measured, and the time length of the synchronization signal measurement window is used for determining cell measurement time.

In a second aspect, a measurement configuration method is provided, where the method of the first aspect may be performed by a second apparatus, which may be a communication device or a communication apparatus capable of supporting the communication device to implement the functions required by the method, such as a system-on-chip. Illustratively, the communication device may be a terminal. The method comprises the following steps: the terminal receives measurement configuration information from the network equipment, wherein the measurement configuration information is used for configuring a measurement interval parameter and the time length of a synchronization signal measurement window, the measurement interval parameter is used for the terminal to measure a reference signal to be measured, the time length of the synchronization signal measurement window is used for determining cell measurement time, and the measurement interval parameter and the time length of the synchronization signal measurement window are configured according to a subcarrier spacing SCS; and the terminal determines a measurement interval according to the measurement interval parameter and the time length of the synchronization signal measurement window, and measures the reference signal to be measured according to the measurement interval.

In aspects of the first and second aspects, the network device may configure the measurement interval parameter and the time length of the synchronization signal measurement window according to the SCS. In other words, the measurement interval parameter and the time length of the synchronization signal measurement window are related to the SCS, which can ensure that the configured measurement interval is smaller when the SCS is greater than or equal to 240 KHz. The measurement interval configured when the SCS is greater than or equal to 240KHz can be ensured, and the measurement interval configured by the SCS below 120KHz can be ensured, so that the resource for cell measurement is saved.

Since the SCS is greater than or equal to 240KHz when the system is applied to a frequency band greater than or equal to 52.6GHz, the network device generates the measurement configuration information according to the SCS, which may also be considered as that the network device generates the measurement configuration information according to the frequency band, that is, the measurement interval parameter and the time length of the synchronization signal measurement window are configured according to the frequency band. For example, the frequency bands can be FR1 located at 0-7.125 GHz, FR2 located at 7.125 GHz-52.6 GHz, FR3 located at 52.6GHz-100GHz, and the like.

The scheme can be considered as the measurement interval under the condition of being less than or equal to 120kHz, namely, some possible smaller values of the measurement interval are added in the existing measurement interval set, so that the resource waste of measurement can be reduced under the condition of being more than or equal to 240kHz, and the configuration of the measurement interval under the condition of being less than or equal to 120kHz can be compatible.

In a possible implementation manner, there may be at least two SCS types, where the at least two SCS types include a first SCS and a second SCS, and a value in a first set corresponding to the first SCS may be different from a value in a first set corresponding to the second SCS.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the embodiments of the present application will be described in further detail with reference to the accompanying drawings.

The technical solutions of the embodiments of the present application described below may be applied to a communication system as shown in fig. 2, where the communication system may include a network side device and a User Equipment (UE) communicating with the network side device. Fig. 2 is an example of the communication system, and the communication system shown in fig. 2 includes one network-side device and 1 user device communicating therewith, and in fact, the communication system may include a plurality of user devices, which is not limited in this embodiment of the present application.

The network side device may be a device capable of communicating with the user equipment, and is also referred to as a network device. The network device may be an access network device, and the access network device may also be referred to as a Radio Access Network (RAN) device, which is a device providing a wireless communication function for the terminal device.

User equipment, also referred to as terminal equipment or terminal, or terminal equipment, includes equipment providing voice and/or data connectivity to a user, which may include, for example, handheld devices having wireless connection capability or processing devices connected to wireless modems. The terminal device may communicate with a core network via a Radio Access Network (RAN), exchanging voice and/or data with the RAN. The terminal device may include a User Equipment (UE), a wireless terminal device, a mobile terminal device, a device-to-device communication (D2D) terminal device, a V2X terminal device, a machine-to-machine/machine-type communication (M2M/MTC) terminal device, an internet of things (IoT) terminal device, a subscriber unit (subscriber unit), a subscriber station (subscriber state), a mobile station (mobile state), a remote station (remote state), an access point (access point, AP), a remote terminal (remote terminal), an access terminal (access terminal), a user terminal (user terminal), a user agent (user agent), a passenger plane (e.g., an unmanned plane, a hot-air balloon, or the like), or a user equipment (user), etc. For example, mobile telephones (or so-called "cellular" telephones), computers with mobile terminal devices, portable, pocket, hand-held, computer-embedded mobile devices, and the like may be included.

By way of example and not limitation, in the embodiments of the present application, the in-vehicle apparatus placed or mounted on the vehicle may further include a wearable device. Wearable equipment can also be called wearable smart device or intelligent wearable equipment etc. is the general term of using wearable technique to carry out intelligent design, develop the equipment that can dress to daily wearing, like glasses, gloves, wrist-watch, dress and shoes etc.. A wearable device is a portable device that is worn directly on the body or integrated into the clothing or accessories of the user.

The generalized wearable smart device includes full functionality, large size, and can implement full or partial functionality without relying on a smart phone, such as: smart watches or smart glasses and the like, and only focus on a certain type of application functions, and need to be used in cooperation with other devices such as smart phones, such as various smart bracelets, smart helmets, smart jewelry and the like for monitoring physical signs.

In addition, the embodiment of the application can also be applied to other communication technologies facing the future. The network architecture and the service scenario described in this application are for more clearly illustrating the technical solution of this application, and do not constitute a limitation to the technical solution provided in this application, and it can be known by those skilled in the art that the technical solution provided in this application is also applicable to similar technical problems along with the evolution of the network architecture and the appearance of new service scenarios.

Due to the mobility of the terminal, the terminal may move from the coverage of one cell to the coverage of another cell, and in order to ensure the service continuity and the communication quality of the terminal, the terminal may perform cell reselection (reselection) or cell handover (handover). Both cell reselection and cell handover require the terminal to perform cell measurements, i.e. the terminal performs RRM measurements.

The network device may take measurements of neighboring cells using the SSB or CSI-RS as beam signals. The network device may configure the measurement gap, e.g., to make RRM measurements based on the configured measurement gap. For example, the network device may configure a period of the SMTC, a duration of the SMTC, and an offset value of the SMTC, and the terminal may determine the cell measurement time according to the period of the SMTC, the duration of the SMTC, and the offset value of the SMTC. And the terminal determines the measurement gap according to the cell measurement time and the measurement switching time. For example, in the process defined by the 38-series protocol of the 15 th release of the third generation partnership project (3 GPP), the single measurement handover time is defined to be 0.25ms in the case of the high frequency band and 0.5ms in the case of the low frequency band.

Current communication systems, such as Long Term Evolution (LTE) systems, are applied to carrier bands smaller than 52.6 GHz. The subcarrier width of the data, which may also be referred to as subcarrier spacing (SCS), may be 15KHz, 30KHz, 60KHz, 120 KHz. The SCS is an interval value between center positions or peak positions of two subcarriers adjacent to each other in a frequency domain in an Orthogonal Frequency Division Multiplexing (OFDM) system. For SCS, the following table 1 can be referred to:

TABLE 1

μ	Δf＝2^μ·15[kHz]
		0	15
1	30
		2	60
3	120
		4	240

Where μ is used to indicate the subcarrier spacing, for example, when μ is 0, the subcarrier spacing is 15kHz, and when μ is 1, the subcarrier spacing is 30 kHz. In an NR system, a carrier band greater than or equal to 52.6GHz may be supported, with greater subcarrier spacing supported due to the higher carrier frequency, e.g., the width of the supportable subcarriers may include 240KHz, 480KHz, 960KHz, 1920KHz, 3840KHz, etc.

The length of one time slot corresponding to different subcarrier spacings is different, the length of one time slot corresponding to a subcarrier spacing of 15kHz is 0.5ms, the length of one time slot corresponding to a subcarrier spacing of 60kHz is 0.125ms, and so on. From this point of view, μ can be considered as a parameter that determines the frequency-domain width and time-domain length of one OFDM subcarrier signal. In the NR system, "Numerology" is introduced for determining a frequency domain width and a time domain width of an OFDM subcarrier signal, where μmay be considered as a configuration index of the Numerology, so the NR system may also be considered to support a plurality of numerologies. For convenience of description, Numerology is hereinafter referred to as parameter set, i.e., a parameter representing a frequency domain width and a time domain width for determining an OFDM subcarrier signal.

One SMTC may be configured for one subcarrier. Since SSBs are transmitted by the network device based on beams, different beams correspond to different cell coverage areas and also correspond to different SSBs, different SSBs may correspond to different SMTCs. In the LTE system, the period of the SMTC may be 5ms, 10ms, 20ms, 40ms, 80ms, and 160ms, and a specific value may be configured by a system message. The duration of the SMTC may be 1ms, 2ms, 3ms, 4ms or 5 ms. The offset value for SMTC may be {0, 1, …, period-1 } ms for SMTC. As the subcarrier width of the data increases, the duration length of the SSB decreases, for example, the subcarrier width of the data is 240KHz, the duration of the SSB is 2.25ms, the subcarrier width of the data is 480KHz, and the duration of the SSB is 1.125 ms.

In some embodiments, for low frequency measurements, the measurement gap comprises 3ms, 4ms, or 6 ms; for high frequency measurements, the measurement gap may be 1.5ms, 3.5ms, or 5.5 ms. The specific measurement gap may be configured by the measurement pattern as described in table 2.

TABLE 2 configuration Pattern for measurement of gap

And because the terminal supports the evolved universal terrestrial radio access and the new air interface dual connection (EN-DC) architecture, the terminal can have two sets of transceiving systems. For a terminal under the EN-DC architecture, for example, if the serving cell of the terminal is an LTE cell, if the terminal is to perform measurement on a corresponding NR cell, the LTE base station may not configure a measurement gap for the terminal if the LTE base station recognizes that the terminal performs only inter-system measurement (i.e., only measures NR cells and does not measure other LTE cells), and the frequency to be measured and the frequency of the current serving cell belong to an EN-DC frequency combination supported by the terminal. The measurement gap configuration of the specific terminal may refer to tables 3 and 4, and configure different values for different frequency bands.

Wherein, the low frequency band is located at FR1(frequency range1, which can be marked as FR1) of 0-7.125 GHz, the higher frequency band is located at 7.125 GHz-52.6 GHz (frequency range2, which can be marked as FR2), and relatively speaking, the frequency band greater than 52.6GHz-100GHz is marked as FR 3. E-UTRA denotes LTE networks. non-NR RAT means networks other than 5G, including 4G, 3G and 2G networks. As can be seen from tables 3 and 4, when FR1 measures FR1, Gap needs to be measured; or when FR2 is measured by FR2, gap measurement is required, otherwise gap measurement is not required.

TABLE 3 application of measurement gap in 5G and other network systems combined networking

TABLE 4 application of measurement gap in 5G independent networking

In the NR system, since the carrier frequency is higher, a larger subcarrier spacing is supported, for example, supportable subcarrier widths include 240KHz, 480KHz, 960KHz, 1920KHz, 3840 KHz. In this case, if the gap configured below 120KHz is used, it is apparent that the measurement time is long, resulting in a waste of resources.

In view of this, embodiments of the present application provide a measurement configuration method and a communication apparatus, which configure a smaller measurement gap in an application scenario of an SCS larger than 120KHz, so as to save system resources as much as possible.

The two technical solutions provided by the embodiments of the present application can be applied to various communication systems, for example: long Term Evolution (LTE) systems, fifth generation (5G) systems, such as New Radio (NR) systems, and next generation communication systems, such as 6G systems. Of course, the technical solution of the embodiment of the present application may also be applied to other communication systems as long as the communication system has a requirement of beam switching.

The embodiments of the present application will be described in detail with reference to the accompanying drawings.

It should be understood that the terms "system" and "network" in the embodiments of the present application may be used interchangeably. "at least one" means one or more, "a plurality" means two or more. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone, wherein A and B can be singular or plural. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship. "at least one of the following" or similar expressions refer to any combination of these items, including any combination of the singular or plural items. For example, at least one (one) of a, b, or c, may represent: a, b, c, a and b, a and c, b and c or a, b and c, wherein a, b and c can be single or multiple.

And, unless stated to the contrary, the embodiments of the present application refer to the ordinal numbers "first", "second", etc., for distinguishing a plurality of objects, and do not limit the sequence, timing, priority, or importance of the plurality of objects. For example, the first message and the second message are only used for distinguishing different messages, and do not indicate the difference of the priority, the transmission order, the importance degree, or the like of the two messages.

Additionally, the terms "system" and "network" are often used interchangeably herein. The term "and/or" herein is merely an association describing an associated object, meaning that three relationships may exist, e.g., a and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.

It should be understood that in the embodiment of the present application, "B corresponding to a" means that B is associated with a, from which B can be determined. It should also be understood that determining B from a does not mean determining B from a alone, but may be determined from a and/or other information.

Referring to fig. 3, a schematic flow chart of a measurement configuration method according to an embodiment of the present application is shown, and in the following description, the method is applied to the communication system shown in fig. 2 as an example. In addition, the method may be performed by two communication devices, e.g. a first communication device and a second communication device. For convenience of introduction, in the following, the method is taken as an example executed by a network device and a terminal, and the network device is taken as an example of a base station, that is, the first communication device is taken as a terminal, and the second communication device is taken as an example of a base station.

Specifically, the flow of the measurement configuration method provided in the embodiment of the present application is described as follows.

S301, the base station generates measurement configuration information, wherein the measurement configuration information is used for configuring a measurement interval parameter and the time length of a synchronization signal measurement window, the measurement interval parameter is used for a terminal to measure a reference signal to be measured, and the time length of the synchronization signal measurement window is used for determining cell measurement time.

In the embodiment of the present application, the reference signal to be measured may include an SS and/or a CSI-RS, but may also include other reference signals. The terminal can complete the synchronization with the cell and the like by measuring the SS. The CSI-RS is a cell-based reference signal, and may be used for measuring information such as a Channel Quality Indicator (CQI), a Precoding Matrix Indicator (PMI), and a Rank Indicator (RI). In some embodiments, both idle (idle) and connected (connected) terminals may perform measurements based on the SS, and the connected terminal may perform measurements based on the CSI-RS in addition to the SS. However, before measuring the CSI-RS, the terminal needs to first obtain synchronization of the cell by measuring the SS, that is, obtain time information of the cell, otherwise, the terminal cannot know the occurrence position of the CSI-RS and cannot perform measurement. And the terminal acquires the time information of the cell through the measurement of the SS, thereby completing the measurement of the CSI-RS appearing later. It should be understood that the reference signal to be measured may be a reference signal transmitted by the base station, and may also include a reference signal transmitted by other network equipment besides the base station.

The measurement interval parameters may include a length of the Measurement Gap (MGL) and a period of the Measurement Gap (MGRP), as well as a timing advance of the measurement gap. The base station may determine to configure a value of a measurement interval parameter for the terminal according to an agreement, for example, the base station may configure a measurement interval, may configure a measurement interval period, and may configure an offset value of the measurement interval. It should be noted that the agreement here may be a agreement or an agreement between the base station and the terminal.

For example, the convention may be a corresponding relationship between a frequency band configured by the serving cell and a value of the measurement interval parameter. For example, as shown in table 5 below, one possible measurement interval configuration pattern is shown, i.e., possible values of MGL and MGRP are shown.

TABLE 5 configuration Pattern for measurement of gap

As can be seen from tables 5 and 2, table 5 has more possible values of MGL and MGRP, i.e., the value of MGL may be 2.5ms, when the interval pattern index is 24 to 27 compared to table 2. Of course, in other embodiments, when the space pattern index is 24-27, the value of MGL may also be 2ms, etc., which is not illustrated here.

It should be understood that, the SCS here may be a subcarrier width for transmitting the reference signal, and if the SCS is greater than 120kHz, for example, the SCS is equal to 240kHz, it may also be understood that if the frequency band configured by the serving cell is greater than 56.2GHz, if the MGL and MGRP are configured by using the spacing pattern indexes [0-23], it is obvious that the value of the measurement gap finally configured is large, and the resource overhead of measurement is wasted. For this reason, in the embodiment of the present application, the MGL and the MGRP may be configured with the space pattern indexes [24-27] to reduce the value of the measurement gap and reduce the resource overhead of the measurement. In other words, in the embodiment of the present application, the base station may configure the measurement gap according to the SCS, i.e., the measurement interval is related to the SCS. For example, when the SCS is greater than or equal to 240kHz, the base station takes the minimum value of the measurement gap configured by the SCS as the first value; and when the SCS is less than or equal to 120kHz, the base station takes the minimum value of the measurement gap configured by the SCS as a second value, and the first value is less than the second value. That is, SCS greater than or equal to 240kHz is configured to have smaller gap than less than or equal to 120kHz, thereby reducing the resource overhead of the measurements.

In some embodiments, when the single measurement handover time is 0.5ms, the frequency band configured by the serving cell is FR3, and the maximum MGL value may be 3.5ms, i.e. the measurement interval parameter may be configured using the interval pattern index [16-27] as in table 5. The base station can measure any one of the following cells according to the measurement interval parameter configured by the interval pattern index [16-27] in table 5: a cell with a frequency band of FR3, a cell with a frequency band of FR3 and FR2, a cell with a frequency band of FR3 and FR1, a cell with a frequency band of FR3 and E-UTRA, or a cell with a frequency band of FR3, FR1 and FR2, a cell with a frequency band of FR3, FR2 and E-UTRA, a cell with a frequency band of FR3, FR1 and E-UTRA, or a cell with a frequency band of FR3, FR1, FR2 and E-UTRA. The base station can configure the measurement interval according to the frequency band of the cell, so as to reduce the resource overhead of measurement as much as possible.

Illustratively, the base station may configure the measurement interval to be any one value in the first set. The first set may include at least two values of 1ms, 1.25ms, 1.5ms, 2ms, 2.25ms, 2.5ms, 3ms, 3.25ms, and 3.5 ms. In other words, the first set may be a set consisting of at least two values of 1ms, 1.25ms, 1.5ms, 2ms, 2.25ms, 2.5ms, 3ms, 3.25ms, and 3.5 ms.

For example, the base station may configure the measurement interval to be any one value in set 1. The set 1 may be [1ms, 2.5ms, 3.5ms ], [1ms, 1.5ms, 3.5ms ], [1ms, 2.5ms, 3.5ms ], [1.5ms, 2ms, 3.5ms ], [2.5ms, 2ms, 3.5ms ], [1ms, 2ms, 3ms ], etc., that is, the measurement interval is less than or equal to 3.5ms, which may be applicable to a scenario in which SCS is greater than or equal to 240kHz, and may reduce the resource overhead of measurement.

As another example, the base station may configure the measurement interval to be any one value in set 2. The set 2 may be [1ms, 1.5ms, 2ms, 3ms, 3.5ms, 4ms, 5.5ms, 6ms ], [1ms, 1.5ms, 2ms, 2.5ms, 3ms, 3.5ms, 4ms, 5.5ms, 6ms ], [1ms, 1.5ms, 2ms, 2.5ms, 3ms, 3.5ms, 4ms, 5.5ms, 6ms ], [1.5ms, 2ms, 2.5ms, 3ms, 3.5ms, 4ms, 5.5ms, 6ms ] or [1.5, 2.5ms, 3.5ms, 5ms, 6ms, 5.5ms, 5ms, 6ms, etc. It can be understood that some possible smaller values of the measurement interval are added to the existing set of measurement intervals, which can not only ensure that the resource waste of measurement is reduced under the condition of being greater than or equal to 240kHz, but also be compatible with the configuration of the measurement interval under the condition of being less than or equal to 120 kHz.

The base station can also configure the time length of the synchronization signal measurement window, i.e. the length of the SMTC, according to the value of the SCS. The different values of the SCS correspond to the different values of the SMTC. When the SCS is large, the length of the SMTC may be reduced in order to minimize overhead waste of the measurement. For example, in some embodiments, when SCS is equal to 240kHz, the SMTC values are in set 1; when SCS is equal to 480kHz, the value of SMTC is in a set 2; when SCS is equal to 960kHz, the value of SMTC is in set 3; when SCS equals 1920kHz, the SMTC value is in set 4. The values in the set 1, the set 2, the set 3, and the set 4 may be values in any one or more of the following sets: [1ms, 2ms, 3ms ], [0.5ms, 1ms, 2ms ], [0.25ms, 0.5ms, 1ms, 2ms, 3ms ], [0.25ms, 0.5ms, 1ms, 2ms ], [0.25ms, 0.5ms, 1ms ], and [0.5ms, 1ms, 1.5ms ]. Set 1, set 2, set 3, and set 4 may include the same values. For example, set 1 may be [1ms, 2ms, 3ms ], set 2 may be [0.5ms, 1ms, 2ms ], and set 3 may be [0.25ms, 0.5ms, 1ms ]. The set 1, the set 2, the set 3 and the set 4 respectively comprise different values, so that the difficulty of protocol design can be reduced, and the expense and resources for configuring the measurement interval parameters are saved.

The base station can also configure the length of the SMTC according to the frequency band or the SCS, and the values of different carriers or frequency bands correspond to different values of the SMTC. When the carrier or frequency band is large, the length of the SMTC can be reduced in order to minimize the overhead waste of measurement. For example, in some embodiments, when the carrier or frequency band is FR3, the value of SMTC is in set 1; when the carrier or frequency band is FR2, the value of SMTC is in set 3. When the value in the set 1 may be a value in any one or more of the following sets: [1ms, 2ms, 3ms ], [0.5ms, 1ms, 2ms ], [0.25ms, 0.5ms, 1ms, 2ms, 3ms ], [0.25ms, 0.5ms, 1ms, 2ms ], [0.25ms, 0.5ms, 1ms ], and [0.5ms, 1ms, 1.5ms ]. The value of set 2 may be [1ms, 2ms, 3ms, 4ms, 5ms ]. The set 1 and the set 2 respectively comprise different values, so that the difficulty of protocol design can be reduced, and the expense and resources for configuring the measurement interval parameters are saved.

Yet another example, as shown in table 6 below, shows another possible measurement interval configuration pattern, i.e., showing possible values for MGL and MGRP.

TABLE 6 configuration pattern for measuring gap

As can be seen from tables 6 and 2, table 6 has more possible values of MGL and MGRP, i.e., the value of MGL may be 1.25ms, when the space pattern index is 24 to 35 compared to table 2. Of course, in other embodiments, when the space pattern index is 24-35, the value of MGL may also be 1ms, etc., which is not illustrated here.

It should be understood that if the SCS is greater than 120kHz, for example, the SCS is equal to 240kHz, it can also be understood that if the frequency band configured by the serving cell is greater than 56.2GHz, if the MGL and MGRP are configured by using the space pattern indexes [24-35], it is obvious that the value of the measurement gap finally configured is large, and the resource overhead of the measurement is wasted. For this reason, in the embodiment of the present application, the MGL and the MGRP may be configured with the space pattern indexes [24-35] to reduce the value of the measurement gap and reduce the resource overhead of the measurement.

For example, when the single measurement handover time is 0.25ms, the frequency band configured by the serving cell is FR3, and the maximum value of MGL may be 1.25ms, i.e. the measurement interval parameter may be configured using the interval pattern index [24-35] as in table 6. The base station can measure any one of the following cells according to the measurement interval parameter configured by the interval pattern index [24-35] in table 6: a cell with a frequency band of FR3, a cell with a frequency band of FR3 and FR2, a cell with a frequency band of FR3 and FR1, a cell with a frequency band of FR3 and E-UTRA, or a cell with a frequency band of FR3, FR1 and FR2, a cell with a frequency band of FR3, FR2 and E-UTRA, a cell with a frequency band of FR3, FR1 and E-UTRA, or a cell with a frequency band of FR3, FR1, FR2 and E-UTRA.

The set of possible values for the base station configurable measurement interval may be [1.25ms, 2.25ms, 3.25ms, 1.5ms, 4ms, 3ms, 3.5ms, 4.5ms, 5.5ms, 6ms ].

For example, the base station may configure the measurement interval to be any one value in set 1. The set 1 may be [1.25ms, 2.25ms, 3.25ms ], [1ms, 2.25ms, 3.25ms ] ], [1ms, 2ms, 3.25ms ], [1ms, 1.5ms, 3.25ms ], [1.25ms, 2.5ms, 3.25ms ], etc., that is, the measurement interval is less than or equal to 3.25ms, which may be applicable to the SCS greater than or equal to 240kHz, and may reduce the resource overhead of measurement.

As another example, the base station may configure the measurement interval to be any one value in set 2. The set 2 can be [1.25ms, 2.25ms, 3.25ms, 1.5ms, 3ms, 3.5ms, 4ms, 5.5ms, 6ms ], [1ms, 2ms, 3.25ms, 1.5ms, 3ms, 3.5ms, 4ms, 5.5ms, 6ms ], [1.5ms, 2.25ms, 3.25ms, 1.5ms, 3.5ms, 4ms, 5.5ms, 6ms ], [1ms, 2ms, 1.5ms, 3ms, 3.5ms, 4ms, 5.5ms, 6ms ], [1.25ms, 2.25ms, 3.25ms, 1.5ms, 3.5ms, 4ms, 5ms, 6ms ], etc. It can be understood that some possible smaller values of the measurement interval are added to the existing set of measurement intervals, which can not only ensure that the resource waste of measurement is reduced under the condition of being greater than or equal to 240kHz, but also be compatible with the configuration of the measurement interval under the condition of being less than or equal to 120 kHz.

The base station can also configure the length of the SMTC according to the value of the SCS, and different values of the SCS correspond to different values of the SMTC. When the SCS is large, the length of the SMTC may be reduced in order to minimize overhead waste of the measurement. For example, in some embodiments, when SCS is equal to 240kHz, the SMTC values are in set 1; when SCS is equal to 480kHz, the value of SMTC is in a set 2; when SCS is equal to 960kHz, the value of SMTC is in set 3; when SCS equals 1920kHz, the SMTC value is in set 4. The values in the set 1, the set 2, the set 3, and the set 4 may be values in any one or more of the following sets: [1ms, 2ms, 3ms ], [0.5ms, 1ms, 2ms ], [0.25ms, 0.5ms, 1ms, 2ms, 3ms ], [0.25ms, 0.5ms, 1ms, 2ms ], [0.25ms, 0.5ms, 1ms ], and [0.5ms, 1ms, 1.5ms ]. Set 1, set 2, set 3, and set 4 may include the same values. For example, set 1 may be [1ms, 2ms, 3ms ], set 2 may be [0.5ms, 1ms, 2ms ], and set 3 may be [0.25ms, 0.5ms, 1ms ]. The set 1, the set 2, the set 3 and the set 4 respectively comprise different values, so that the difficulty of protocol design can be reduced, and the expense and resources for configuring the measurement interval parameters are saved.

S302, the base station sends measurement configuration information to the terminal, and the terminal receives the measurement configuration information.

After configuring the measurement interval parameter for the terminal, the base station may send measurement configuration information to the terminal, where the measurement configuration information may include the measurement interval parameter configured for the terminal by the base station. For example, if the base station configures a measurement interval and a measurement interval period for the terminal, the measurement configuration information includes the measurement interval and the measurement interval period, and if the base station also configures an offset value of the measurement interval for the terminal, the measurement configuration information also includes the offset value of the measurement interval.

Wherein, if the measurement configuration information includes a measurement interval and a measurement interval period, the base station may send the measurement interval and the measurement interval period to the terminal through one message, so as to save transmission resources. Or the base station may also send the measurement interval and the measurement interval period to the terminal through different messages. If the base station sends the measurement interval and the measurement interval period to the terminal through different messages, the base station may send the measurement interval and the measurement interval period at the same time, or send the measurement interval first and then send the measurement interval period.

In some embodiments, the measurement configuration information may be carried in any one of a Physical Broadcast Channel (PBCH), Remaining Minimum System Information (RMSI), a System Information Block (SIB) 1, an SIB2, an SIB3, a media access control element (MAC-CE), Downlink Control Information (DCI), Radio Resource Control (RRC), and a system message.

After receiving the measurement configuration information, the terminal device may start a corresponding measurement interval according to the measurement configuration information, which is described below.

S303, the terminal determines the time information of the measurement interval according to the measurement interval parameter and the time length of the synchronization signal measurement window included in the measurement configuration information, and measures the reference signal to be measured.

The measurement interval parameters may include a measurement interval, a measurement interval period, and an offset of the measurement interval, etc., wherein the measurement interval, the measurement interval period, and the offset of the measurement interval may be used to determine time information of the measurement interval. It should be noted that, both the base station and the terminal need to determine the time information of the measurement interval, after determining the time information of the measurement interval, the base station may know when the terminal starts the measurement interval, and the terminal may start the measurement interval at the determined position.

The terminal starts the measurement interval in the embodiment of the application, which may mean that the terminal interrupts the data transmission and reception in the working frequency point of the serving cell of the terminal, that is, the terminal interrupts the work in the working frequency point of the serving cell of the terminal and starts to measure the reference signal at other frequency points. As to which frequency point the terminal measures the reference signal to be measured in a measurement interval, the terminal can select itself. For example, the base station indicates a plurality of frequency points other than the operating frequency band (or the center frequency point) of the serving cell of the terminal to the terminal in advance, after the terminal starts a measurement interval, the terminal may select to measure the reference signal to be measured in at least one frequency point indicated by the base station in the measurement interval.

The terminal may determine the time information of the measurement interval according to the length of the measurement interval, the period of the measurement interval, the offset of the measurement interval, etc., for example, the offset of the measurement interval is 0, and then the starting position of the measurement interval and the starting position of the period of the measurement interval are the same position. The measurement interval of the next cycle is separated from the measurement interval of the present cycle by only one cycle. If the offset of the measurement interval is δ, the measurement interval of the next cycle is separated from the measurement interval of the present cycle by one (cycle + δ).

After the terminal determines the time information of the measurement interval, the terminal starts the measurement interval at the start position of the determined measurement interval and measures the reference signal in the started measurement interval.

The technical scheme provided by the embodiment of the application can configure a smaller length of the measurement interval, for example, the length of the measurement interval can be configured to be 1.25ms under the condition that the SCS is greater than or equal to 240kHz, so that the resource overhead of the terminal for cell measurement can be saved as much as possible.
