Fig. 1 is an architecture diagram of a communication system according to an embodiment of the present application. As shown in fig. 1, the terminal device 101, the first network device 102, and the second network device 103 are included. The terminal device 101 is an entity, such as a mobile phone, on the user side for receiving or transmitting signals. A terminal device may also be referred to as a terminal (terminal), a User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (MT), etc. The terminal device may be a mobile phone (mobile phone), a wearable device, a tablet computer (Pad), a computer with a wireless transceiving function, a Virtual Reality (VR) terminal device, an Augmented Reality (AR) terminal device, a wireless terminal in industrial control (industrial control), a wireless terminal in self-driving (self-driving), a wireless terminal in remote surgery (remote management), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation safety, a wireless terminal in city (smart city), a wireless terminal in smart home (smart home), and so on.

The first network device 102 is a network device corresponding to a serving cell of the terminal device 101, and the second network device 103 is a network device corresponding to a neighboring cell. And the adjacent cell a is the adjacent cell of the service cell. It should be noted that the number of adjacent cells included in the communication system shown in fig. 1 is only for example and is not limited to the embodiment of the present application. It should be further noted that, the difference between the network devices corresponding to the serving cell and the neighboring cell a shown in fig. 1 is merely used for example, and does not form a limitation to the embodiment of the present application. For example, the network devices corresponding to the serving cell and the neighboring cell a in fig. 1 may also be the same network device.

In one implementation, the communication system shown in fig. 1 may include other neighboring cells of the serving cell in addition to the neighboring cell a. In fig. 1, the oval area where the first network device 102 is located is a coverage area of a serving cell of the terminal device 101, and the oval area where the second network device 103 is located is a coverage area of a neighboring cell a. The terminal device 101 is simultaneously within the coverage of the serving cell and the neighboring cell a.

For example, the network device may be an evolved NodeB (eNB), a transmission point (TRP), a next generation base station (gNB) in the NR system, a base station in other future mobile communication systems, or an access node in a wireless fidelity (WiFi) system.

For example: a Long Term Evolution (LTE) system, a 5th generation (5G) mobile communication system, and a 5G New Radio (NR) system. Optionally, the method of the embodiment of the present application is also applicable to various future communication systems, such as a 6G system or other communication networks.

In the measurement method shown in fig. 1, the measurement flow mainly includes: the terminal device 101 obtains a frequency set, where the frequency set includes a plurality of frequencies to be measured, for example, the frequency set may include, but is not limited to, one or more of the following: the frequency of target dual connection with a service cell of the terminal equipment and the frequency of target dual connection with a neighboring cell of the service cell; secondly, the terminal equipment 101 acquires frequency indication information; thirdly, the terminal equipment 101 determines the target frequency to be measured from the frequency set according to the frequency indication information; and fourthly, the terminal equipment 101 measures the cell on the target frequency to be measured. For example, taking the example that the cell on the target frequency to be measured includes the neighboring cell a, the terminal device may measure the neighboring cell a as shown in fig. 1.

By the measuring method, the terminal device 101 determines the target frequency to be measured from the plurality of frequencies to be measured in the frequency set according to the frequency indication information, so that the terminal device can be prevented from measuring the frequency to be measured which is not required to be measured in the frequency set, and the power consumption of the terminal device can be reduced.

A detailed description of one of the measurement methods provided herein follows.

Referring to fig. 2, fig. 2 is a flowchart of a measurement method according to an embodiment of the present disclosure. The measurement method may be implemented by the terminal apparatus 101 shown in fig. 1; as shown in fig. 2, the measurement method includes, but is not limited to, the following steps 201 to 204, and the method shown in fig. 2 is described by taking the application to the terminal device 101 as an example.

S201, the terminal equipment acquires a frequency set, wherein the frequency set comprises a plurality of frequencies to be measured.

Specifically, when the terminal device enters the RRC _ IDLE state or the RRC _ INACTIVE state, the network device may instruct the terminal device to perform early measurement, and the terminal device obtains a frequency set for performing early measurement from a system message or a dedicated signaling, where the frequency set includes a plurality of frequencies to be measured. The plurality of frequencies to be measured in the frequency set may include, but are not limited to, one or more of: the frequency of the target dual connection with the service cell of the terminal equipment and the frequency of the target dual connection with the adjacent cell of the service cell. Wherein the target dual connection may be the aforementioned EN-DC and/or NGEN-DC. The system message can be an LTE system message, an NR system message or a system message in other novel mobile communication systems, and the special signaling can be an RRC connection release message.

When the system message is an LTE system message, the set of frequencies carried in the system message may indicate a plurality of frequencies. When the indicated frequency is an NR frequency, the set of frequencies carried in the system message may indicate a plurality of frequencies and subcarrier spacing of each frequency.

When the RRC connection release message carries a frequency set and the LTE system message also carries a frequency set, the frequency set acquired by the terminal device may be the frequency set carried in the RRC connection release message. It should be noted that the frequency set carried by the RRC connection release message and the frequency set carried by the LTE system message may be the same or different.

When the terminal device reselects the serving cell, if the frequency set is carried in the RRC connection release message sent to the terminal device by the historical serving cell, the terminal device may continue to use the frequency set carried in the RRC connection release message; if the RRC connection release message corresponding to the historical serving cell does not carry the frequency set, the frequency set carried in the system message issued by the current serving cell may be obtained.

S202, the terminal equipment acquires frequency indication information.

The frequency indication information may be used to determine a target frequency to be measured from the set of frequencies. In one implementation, the frequency indication information may be carried in a system message from the network device, and optionally, the system message may be a new system message or an existing system message. It should be noted that, in the embodiment of the present application, the name of the new system message is not limited.

In one implementation, the frequency indication information may be used to indicate a frequency band in which a frequency of the target dual connectivity with the serving cell of the terminal device is located. The frequency band is a frequency range of radio waves, for example: the NR frequency band 40 corresponds to 2300MHz-2400 MHz.

In one implementation, the terminal device may receive a first system message from the network device, where the first system message carries frequency indication information. Wherein the first system message may be a newly added system message.

S203, the terminal equipment determines the target frequency to be measured from the frequency set according to the frequency indication information.

After the terminal device obtains the frequency indication information, the target frequency to be measured can be determined from the frequency set according to the frequency indication information. Optionally, the frequency indication information may be used to indicate a position of the target frequency to be measured in the frequency set. For example, if the content indicated by the frequency indication information is that the positions of the target frequency to be measured in the frequency set are the first and the second, the first two frequencies to be measured in the frequency set may be determined as the target frequency to be measured.

In an implementation manner, the terminal device may determine whether each frequency to be measured in the frequency set is within a frequency band indicated by the frequency indication information (i.e., a frequency band in which a frequency for performing a target dual connection with a serving cell of the terminal device is located), and if there is a frequency to be measured in the frequency band indicated by the frequency indication information in the frequency set, determine the frequency to be measured in the frequency band indicated by the frequency indication information as the target frequency to be measured. For example, when the frequency set acquired by the terminal device includes two frequencies to be measured (for example, the frequencies of the NR carrier 2350MHz and 850MHz), and the frequency indication information indicates that the current serving cell can perform the target dual connectivity with the NR frequency band 40. Since the frequency 2350MHz to be measured is in the frequency band 2300MHz-2400MHz indicated by the frequency indication information, the frequency 2350MHz to be measured can be determined as the target frequency to be measured. And the frequency 850MHz to be measured is not in the frequency band 2300MHz-2400MHz, so the frequency 850MHz to be measured is not taken as the target frequency to be measured.

And S204, the terminal equipment measures the cell on the target frequency to be measured.

The number of cells on the target frequency to be measured may be one or more. Specifically, the terminal device may measure all cells on the target frequency to be measured.

In an implementation manner, when the number of cells on the target frequency to be measured is multiple, the terminal device may determine a part of cells from the multiple cells, and measure the determined cells, where the number of the part of cells may be one or more.

The terminal device measuring the cell may refer to performing early measurement on the cell. The process of the terminal device to measure the cell early is as follows: when the terminal device supports the service frequency, the target frequency to be measured and the subcarrier interval to perform target dual connection and acquires the corresponding SSB (Synchronization Signal Block) measurement configuration, the terminal device measures the cell applicable to the target frequency to be measured. And if the measurement result of a certain cell is higher than the quality threshold configured by the base station, the terminal equipment stores the measurement result and the cell physical identifier corresponding to the cell in variables for subsequent reporting to the base station.

In the above embodiment, the terminal device obtains the frequency set and the frequency indication information, determines the target frequency to be measured from the multiple frequencies to be measured in the frequency set according to the frequency band indicated by the frequency indication information, and measures the cell on the target frequency to be measured, so that the terminal device can be prevented from measuring the frequency to be measured which does not need to be measured in the frequency set, and power consumption of the terminal device can be reduced.

Referring to fig. 3, fig. 3 is a flowchart of another measurement method according to an embodiment of the present disclosure, where the measurement method shown in fig. 3 can be implemented by the terminal device 101 shown in fig. 1; as shown in fig. 3, the measurement method includes, but is not limited to, the following steps 301 to 304:

s301, the terminal equipment acquires a frequency set; the frequency set includes a plurality of frequencies to be measured.

Specifically, the terminal device may obtain the frequency set from a system message or an RRC connection release message. Optionally, the system message of the serving cell may also carry serving cell sharing information, where the serving cell sharing information may indicate whether the serving cell of the terminal device is shared by multiple PLMNs (Public Land Mobile networks). For example, the system message of the serving cell carries the frequency set and serving cell sharing information. The frequency set comprises frequencies to be measured 2350MHz and 850MHz, and the service cell is shared by PLMN A and PLMN B.

It should be noted that, the remaining execution process of step S301 may refer to the specific description in step S201 in fig. 2, and is not described herein again.

S302, the terminal device obtains frequency indication information, the frequency indication information is used for indicating a frequency band where a target dual-connection frequency is located with a service cell of the terminal device, the service cell is shared by a plurality of PLMNs, and the frequency indication information is also used for indicating a corresponding relation between each frequency band and each PLMN.

In this embodiment of the application, the frequency indication information may be used to indicate a frequency band (the number of the frequency bands may be multiple) where a frequency for performing a target dual connectivity with a serving cell of the terminal device is located, and may also be used to indicate a correspondence between each frequency band and each PLMN (PLMN sharing the serving cell). Each PLMN may correspond to zero, one, or multiple frequency bands (frequency bands where the frequency of the target dual connectivity with the serving cell of the terminal device is located), and there may be an overlapping portion between the frequency bands corresponding to the PLMNs, in other words, one frequency band may correspond to multiple PLMNs.

As shown in table 1, the frequency indication information includes a frequency band of 2300MHz to 2400MHz, a frequency band of 800MHz to 900MHz, and a PLMN corresponding to each frequency band.

TABLE 1 frequency indication information

Frequency band	PLMN
		2300MHz-2400MHz	PLMN A
800MHz-900MHz	PLMN B

S303, the terminal equipment determines a target frequency band corresponding to the PLMN selected by the terminal equipment from the plurality of frequency bands according to the corresponding relation; the plurality of PLMNs includes a PLMN selected by the terminal device.

When the serving cell is shared by a plurality of public land mobile networks PLMN, the terminal device may determine a frequency band corresponding to the PLMN selected by the terminal device as the target frequency band according to the frequency indication information.

S304, the terminal device determines the frequency to be measured in the target frequency band in the frequency set as the target frequency to be measured.

Specifically, the terminal device may determine whether each frequency to be measured in the frequency set exists in the target frequency band, and if the frequency set has a frequency to be measured in the target frequency band, determine the frequency to be measured in the target frequency band as the target frequency to be measured. Wherein the plurality of PLMNs sharing the serving cell includes a PLMN selected by the terminal device.

For example, when the PLMN selected by the terminal device is PLMN a, the frequency band corresponding to PLMN a in the frequency indication information shown in table 1 is determined as the target frequency band, that is, the frequency band 2300MHz to 2400MHz is determined as the target frequency band. And if the frequency 2350MHz to be measured is in the target frequency range 2300MHz-2400MHz, determining the frequency 2350MHz to be measured as the target frequency to be measured. And if the frequency to be measured is 850MHz not in the target frequency band, the frequency is not taken as the target frequency to be measured.

S305, the terminal equipment measures the cell on the target frequency to be measured.

It should be noted that, the execution process of step S305 may refer to the specific description in step S204 in fig. 2, and is not described herein again.

In one implementation, the set of frequencies may include: the frequency of the target dual connection with the service cell of the terminal equipment and the frequency of the target dual connection with the adjacent cell of the service cell. Through the foregoing methods of S201-S204 and S301-S305, the terminal device may determine, as the target frequency to be measured, a frequency of the target dual connection with the serving cell of the terminal device, and measure the cell on the target frequency to be measured. By the method, the frequency of the target dual connection of the adjacent cell of the service cell in the frequency set can be prevented from being measured, so that the power consumption of the terminal equipment is reduced.

In the above embodiment, the terminal device obtains the frequency set and the frequency indication information, when the serving cell is shared by multiple public land mobile networks PLMN, the target frequency band corresponding to the PLMN selected by the terminal device is determined according to the correspondence between each frequency band indicated by the frequency indication information and each PLMN, the target frequency to be measured is determined from multiple frequencies to be measured in the frequency set according to the target frequency band, and the cell on the target frequency to be measured is measured, so that the terminal device can be prevented from measuring the frequencies to be measured corresponding to other PLMNs except the PLMN selected by the terminal device in the multiple PLMNs sharing the serving cell, and power consumption of the terminal device is reduced.

Referring to fig. 4, fig. 4 is a flowchart of another measurement method provided in the present embodiment, where the measurement method shown in fig. 4 can be implemented by the terminal device 101 shown in fig. 1; as shown in fig. 4, the measurement method includes, but is not limited to, the following steps 401 to 404:

s401, the terminal equipment acquires a frequency set; the frequency set includes a plurality of frequencies to be measured.

It should be noted that, the execution process of step S401 may refer to the specific description in step S201 in fig. 2, and is not described herein again.

For example, table 2 shows a frequency set obtained by the terminal device, where the frequency set includes 2350MHz and 850MHz frequencies to be measured.

TABLE 2 frequency set

Frequency to be measured
	2350MHz
850MHz

S402, the terminal equipment acquires frequency indication information; the frequency indication information is used for indicating dual connection between each frequency to be measured and a service cell of the terminal equipment.

Specifically, the terminal device receives a second system message from the network device corresponding to the current serving cell, where the second system message carries the frequency indication information. The second system message may be an LTE system message or an NR system message, for example, the second system message is an SIB1 message, an SIB2 message, an SIB3 message, or an SIB5 message, and the second system message may also be a newly added system message. In another implementation, the terminal device may obtain the frequency indication information from dedicated signaling. The dedicated signaling may refer to an RRC connection release message. The frequency indication information may be represented by a field added in an LTE system message, an NR system message, or an RRC connection release message. The frequency indication information is used for indicating a dual connection type between the frequency to be tested and the serving cell of the terminal equipment or an identifier for indicating dual connection, and the dual connection between the frequency to be tested and the serving cell of the terminal equipment can include but is not limited to EN-DC and/or NGEN-DC.

For example, the frequency indication information shown in table 3 includes frequencies to be measured 2350MHz and 850MHz, and dual connections between each frequency to be measured and the serving cell of the terminal device: the terminal equipment supports the service cell to carry out EN-DC with the frequency 2350MHz to be tested, and the terminal equipment supports the service cell to carry out NGEN-DC with the frequency 850MHz to be tested.

TABLE 3 frequency indication information

And S403, the terminal equipment determines a target frequency to be measured from the frequency set, and the double connection between the target frequency to be measured and the service cell is the same as the double connection supported by the terminal equipment.

Specifically, the terminal device may determine whether dual connectivity between each frequency to be measured in the frequency set and the serving cell is the same as dual connectivity supported by the terminal device, and if so, determine the frequency to be measured as the target frequency to be measured.

For example, when the dual connection supported by the terminal device is EN-DC, it can be known from the frequency indication information shown in table 3 that the dual connection between the frequency to be measured 2350MHz and the serving cell is EN-DC, which is the same as the dual connection supported by the terminal device, and therefore, it is determined that the frequency to be measured 2350MHz is the target frequency to be measured. The dual connection between the frequency to be measured 850MHz and the serving cell is NGEN-DC, which is different from the dual connection supported by the terminal device, and therefore, the frequency to be measured 850MHz cannot be determined as the target frequency to be measured.

S404, the terminal device measures the cell on the target frequency to be measured.

It should be noted that, the execution process of step S404 may refer to the specific description in step S204 in fig. 2, and is not described herein again.

In the above embodiment, the terminal device obtains the frequency set and obtains frequency indication information, where the frequency indication information is used to indicate dual connectivity between each frequency to be measured and a serving cell of the terminal device; determining a target frequency to be measured from a plurality of frequencies to be measured in a frequency set according to the frequency indication information, wherein the dual connection between the target frequency to be measured and the service cell is the same as the dual connection supported by the terminal equipment; and the terminal equipment measures the cell on the target frequency to be measured. The frequency which does not need to be measured (the frequency which does not need to be measured and the double connection between the serving cell are different from the double connection supported by the terminal equipment) can be prevented from being measured, and the power consumption of the terminal equipment is favorably reduced.

Referring to fig. 5, fig. 5 is a flowchart of another measurement method provided in the present embodiment, where the measurement method shown in fig. 5 can be implemented by the terminal device 101 shown in fig. 1; as shown in fig. 5, the measurement method includes, but is not limited to, the following steps 501 to 505:

s501, the terminal equipment acquires a frequency set; the frequency set includes a plurality of frequencies to be measured.

It should be noted that, the execution process of step S501 may refer to the specific description in step S201 in fig. 2, and is not described herein again.

S502, the terminal equipment acquires frequency indication information; the frequency indication information is used for indicating dual connectivity between the cell on each frequency to be measured and the serving cell of the terminal device.

Specifically, the number of cells on the frequency to be measured may be one or more. The dual connectivity between each cell on the frequency to be measured and the serving cell may be the same or different. The dual connection between the cell on the frequency to be measured and the serving cell may be the aforementioned EN-DC and/or NGEN-DC.

For example, as shown in the frequency indication information in table 4, the frequency indication information includes frequencies to be measured 2350MHz and 850 MHz. The dual connection between the cell b and the serving cell on the frequency 2350MHz to be measured is EN-DC, and the dual connection between the cell c and the serving cell is NGEN-DC. The double connection between the cell d and the service cell on the frequency 850MHz to be measured is NGEN-DC, and the double connection between the cell e and the service cell is NGEN-DC.

TABLE 4 frequency indication information

S503, the terminal equipment determines a target frequency to be measured from the frequency set, and the double connection between at least one cell on the target frequency to be measured and the service cell is the same as the double connection supported by the terminal equipment.

Specifically, the terminal device may determine whether dual connectivity between each cell on each frequency to be measured in the frequency set and the serving cell is the same as dual connectivity supported by the terminal device. And if the dual connection between at least one cell and the service cell exists on the frequency to be measured and is the same as the dual connection supported by the terminal equipment, determining the frequency to be measured as the target frequency to be measured.

For example, when the dual connection supported by the terminal device is EN-DC, it can be known from the frequency indication information shown in table 4 that the dual connection between the cell b and the serving cell exists at 2350MHz of the frequency to be measured is EN-DC, which is the same as the dual connection supported by the terminal device. Therefore, the frequency to be measured 2350MHz of the cell b is determined as the target frequency to be measured. The dual connection between the cell d and the cell e with the frequency to be measured of 850MHz and the serving cell are NGEN-DC, which is different from the dual connection supported by the terminal equipment. Therefore, the frequency to be measured 850MHz is not determined as the target frequency to be measured.

S504, the terminal device determines a target cell from the cells on the target frequency to be measured, and the double connection between the target cell and the service cell is the same as the double connection supported by the terminal device.

Specifically, the number of the target cells may be one or more, and the dual connectivity between the target cell and the serving cell is the same as the dual connectivity supported by the terminal device. For example, when the dual connection supported by the terminal device is EN-DC, the cell b with dual connection EN-DC at the target frequency 2350MHz to be measured in table 4 is determined as the target cell.

And S505, the terminal equipment measures the target cell.

It should be noted that, the execution process of step S505 may refer to the specific description in step S204 in fig. 2, and is not described herein again.

In the above embodiment, the terminal device obtains the frequency set and obtains the frequency indication information, determines a target frequency to be measured from a plurality of frequencies to be measured in the frequency set according to the frequency indication information, determines a target cell from cells on the target frequency to be measured, and the dual connection between the target cell and the serving cell is the same as the dual connection supported by the terminal device; and measuring the target cell. The method can avoid measuring the cell (double connection between the cell without measurement and the service cell, which is different from the double connection supported by the terminal device) which does not need to be measured on the target frequency to be measured, and is beneficial to reducing the power consumption of the terminal device.

In an implementation manner, when the terminal device measures a cell on a target frequency to be measured and reports a measurement result and a cell physical identifier to the base station, the terminal device may further reduce the number of measured frequencies, the number of measured cells, the number of reported frequencies, and/or the number of reported cells according to its dual connectivity and carrier aggregation capability. For example: when the dual connection supported by the terminal device is EN-DC and only 2 carriers can be supported by NR SCG (NR Secondary Cell Group) at most, the terminal device can reduce the number of Cell measurements on the target frequency to be measured.

In an implementation manner, when the number of cells satisfying the reporting requirement after the measurement by the terminal device is completed is K, and K is greater than the threshold M, the measurement may not be performed on other cells any more, that is, the terminal device only needs to measure the strongest K NR cells satisfying the reporting requirement, which is beneficial to reducing the overhead caused by the measurement by the terminal device. Where the threshold M indicates that NR SCG can only support M carriers at most.

Alternatively, K may be increased by an appropriate value based on the threshold M according to actual conditions. For example, in the case that the capability of the terminal device is strong, K may be obtained by adding a larger value to the threshold M; in the case that the capability of the terminal device is weak, K may be increased by a smaller value based on the threshold M. For example, when the threshold M is 2, K may be 3. The K may be configured by a network, or agreed by a protocol, or set and changed by a terminal device, which is not limited in this embodiment of the present application.

In an implementation manner, when reporting the measurement result to the base station, the terminal device may select the measurement result of the Z cell and the corresponding cell physical identifier to report in the N NR cells that have been measured. Optionally, in the reporting process, the first Z measurement results may be selected from the N measurement results in the order from high to low. By the method, the signaling overhead of reporting is reduced. Wherein N is greater than Z. Z may be K as described above, or Z may be greater than K.
