The technical scheme in the embodiment of the application will be described below with reference to the accompanying drawings.

Fig. 1 is a schematic 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 on the user side for receiving or transmitting signals, such as a mobile phone. The 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, a wearable device, a tablet (Pad), a computer with wireless transceiving function, a Virtual Reality (VR) terminal device, an augmented reality (augmented reality, AR) terminal device, a wireless terminal in industrial control (industrial control), a wireless terminal in unmanned (self-driving), a wireless terminal in teleoperation (remote medical surgery), a wireless terminal in smart grid (SMART GRID), a wireless terminal in transportation security (transportation safety), a wireless terminal in smart city (SMART CITY), a wireless terminal in smart home (smart home), etc. The embodiment of the application does not limit the specific technology and the specific equipment form adopted by the terminal equipment.

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. Wherein the neighbor cell a is a neighbor cell of the serving cell. It should be noted that the number of neighbors 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 neighbor cell a shown in fig. 1 is merely for example, and does not limit the embodiments of the present application. For example, the network devices corresponding to the serving cell and the neighbor 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 neighbors of the serving cell in addition to neighbor a. In fig. 1, the oval area where the first network device 102 is located is the coverage area of the serving cell of the terminal device 101, and the oval area where the second network device 103 is located is the coverage area of the neighboring cell a. The terminal device 101 is simultaneously within the coverage of the serving cell and the neighbor cell a.

A network device (e.g., network device 102, network device 103) is an entity on the network side that transmits or receives signals. For example, the network device may be an evolved NodeB (eNB), a transmission point (transmission reception point, TRP), a next generation NodeB (gNB) in an NR system, a base station in other future mobile communication systems, or an access node in a wireless fidelity (WIRELESS FIDELITY, wiFi) system, etc. The embodiment of the application does not limit the specific technology and the specific equipment form adopted by the network equipment.

It should be noted that the technical solution of the embodiment of the present application may be applied to various communication systems. For example: long term evolution (long term evolution, LTE) system, fifth generation (5th generation,5G) mobile communication system, 5G New Radio (NR) system. Optionally, the method according to 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 flow of measurement mainly includes: ① The terminal device 101 obtains a frequency set comprising a plurality of frequencies to be measured, e.g. the frequency set may include, but is not limited to, one or more of the following: the frequency of target double connection with the service cell of the terminal equipment and the frequency of target double connection with the neighbor cell of the service cell; ② The terminal device 101 acquires frequency indication information; ③ The terminal equipment 101 determines a target frequency to be measured from the frequency set according to the frequency indication information; ④ The terminal device 101 performs measurements on cells on the target frequency to be measured. For example, taking an example that the cell on the target frequency to be measured includes a neighboring cell a, the terminal device may measure the neighboring cell a as shown in fig. 1.

By the measuring method, the terminal equipment 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 equipment can be prevented from measuring the frequencies to be measured which are not required to be measured in the frequency set, and the power consumption of the terminal equipment can be reduced.

A measurement method provided by the present application will be described in detail.

Referring to fig. 2, fig. 2 is a flowchart of a measurement method according to an embodiment of the application. The measurement method may be implemented by the terminal device 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 as being applied to the terminal apparatus 101 as an example.

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

Specifically, when the terminal device enters the rrc_idle state or the rrc_inactive state, the network device instructs 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 under test in the set of frequencies may include, but are not limited to, one or more of the following: the frequency of the target double connection with the service cell of the terminal equipment and the frequency of the target double connection with the neighbor cell of the service cell. Wherein the target double connection may be EN-DC and/or NGEN-DC as described above. The system message may be an LTE system message, an NR system message, or a system message in other new mobile communication systems, and the dedicated signaling may 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 the respective frequencies.

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 may be the same as or different from the frequency set carried by the LTE system message.

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

S202, the terminal equipment acquires the frequency indication information.

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

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

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

S203, the terminal equipment determines a 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. Alternatively, the frequency indication information may be used to indicate the location of the target frequency to be measured in the frequency set. For example, if the content indicated by the frequency indication information indicates that the positions of the target to-be-measured frequencies in the frequency set are the first and second, the first two to-be-measured frequencies in the frequency set may be determined as the target to-be-measured frequencies.

In one implementation manner, the terminal device may determine whether each frequency to be measured in the frequency set is in a frequency band indicated by the frequency indication information (i.e., a frequency band in which a frequency for performing 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 (such as frequencies 2350MHz and 850MHz of the NR carrier), and the frequency indication information indicates that the current serving cell can make the target dual connectivity with the NR frequency band 40. Because the frequency to be measured 2350MHz is in the frequency band 2300MHz-2400MHz indicated by the frequency indication information, the frequency to be measured 2350MHz can be determined as the target frequency to be measured. Because the measured frequency 850 is not in the frequency band 2300MHz-2400MHz, the measured frequency 850MHz is not the target measured frequency.

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 to-be-measured frequency.

In one implementation, 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 multiple.

The terminal device making measurements of a cell may refer to making early measurements of the cell. The process of early measurement of the cell by the terminal equipment is as follows: when the terminal equipment supports the service frequency, the target to-be-measured frequency and the subcarrier interval to perform target double connection and acquires corresponding SSB (Synchronization Signal Block, synchronous signal block) measurement configuration, the terminal equipment measures a cell applicable to the target to-be-measured frequency. 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 a variable 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 to-be-measured frequency from the plurality of to-be-measured frequencies in the frequency set according to the frequency band indicated by the frequency indication information, and measures the cell on the target to-be-measured frequency, so that the terminal device can be prevented from measuring the to-be-measured frequency in the frequency set without measurement, thereby being beneficial to reducing the power consumption of the terminal device.

Referring to fig. 3, fig. 3 is a flowchart of another measurement method according to an embodiment of the present application, where the measurement method shown in fig. 3 may 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, a terminal device acquires a frequency set; the set of frequencies includes a plurality of frequencies to be measured.

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

It should be noted that, the rest of the execution process of step S301 may be referred to the detailed description in step S201 in fig. 2, and will not be repeated here.

S302, the terminal equipment acquires frequency indication information, wherein the frequency indication information is used for indicating a frequency band where a frequency of target double connection is located with a service cell of the terminal equipment, the service cell is shared by a plurality of PLMNs, and the frequency indication information is also used for indicating the corresponding relation between each frequency band and each PLMNs.

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

As shown in the frequency indication information in table 1, the frequency indication information includes frequency bands 2300MHz-2400MHz and 800MHz-900MHz, and PLMNs corresponding to the respective frequency bands.

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 a 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 PLMNs, the terminal device may determine a frequency band corresponding to the PLMN selected by the terminal device as a target frequency band according to the frequency indication information.

S304, the terminal equipment 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 to be measured in the target frequency band exists in the frequency set, determine the frequency to be measured in the target frequency band as the target frequency to be measured. Wherein the multiple PLMNs sharing the serving cell include PLMNs 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-2400MHz is determined as the target frequency band. And if the frequency 2350MHz to be measured is in the target frequency band 2300MHz-2400MHz, determining the frequency 2350MHz to be measured as the target frequency to be measured. And because the 850MHz frequency to be measured is 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 be referred to the specific description in step S204 in fig. 2, and will not be repeated here.

In one implementation, the set of frequencies may include: the frequency of the target double connection with the service cell of the terminal equipment and the frequency of the target double connection with the neighbor cell of the service cell. Through the methods of S201-S204, 301-S305, the terminal device may determine the frequency of the target dual connection with the serving cell of the terminal device as the target frequency to be measured, and measure the cell on the target frequency to be measured. By the method, the measurement of the frequency of the target double connection of the neighbor cell of the service cell in the frequency set can be avoided, and therefore the power consumption of the terminal equipment can be reduced.

In the above embodiment, when the serving cell is shared by a plurality of public land mobile networks PLMNs, the terminal device obtains the frequency set and the frequency indication information, determines the target frequency band corresponding to the PLMN selected by the terminal device according to the correspondence between each frequency band indicated by the frequency indication information and each PLMN, determines the target frequency to be measured from a plurality of frequencies to be measured in the frequency set according to the target frequency band, and measures the cell on the target frequency to be 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 plurality of PLMNs sharing the serving cell, thereby being beneficial to reducing the power consumption of the terminal device.

Referring to fig. 4, fig. 4 is a flowchart of another measurement method according to an embodiment of the present application, where the measurement method shown in fig. 4 may 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, acquiring a frequency set by a terminal device; the set of frequencies includes a plurality of frequencies to be measured.

It should be noted that, the execution of step S401 may be described in detail in step S201 in fig. 2, and will not be described here.

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

TABLE 2 frequency aggregation

Frequency to be measured
	2350MHz
850MHz

S402, the terminal equipment acquires frequency indication information; the frequency indication information is used for indicating the dual connection between each frequency to be measured and the 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 frequency indication information. The second system message may be an LTE system message or an NR system message, for example, the second system message may be an SIB1 message, an SIB2 message, an SIB3 message, an SIB5 message, or the like, 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 newly added in an LTE system message, an NR system message, or an RRC connection release message. The frequency indication information is used to indicate a dual connection type between the frequency to be measured and the serving cell of the terminal device or an identifier used to indicate the dual connection, and the dual connection between the frequency to be measured and the serving cell of the terminal device may include, but is not limited to, EN-DC and/or NGEN-DC.

For example, the frequency indication information as shown in table 3 includes frequencies to be measured 2350MHz and 850MHz, and dual connections between the respective frequencies to be measured and the serving cell of the terminal device: the terminal equipment supports EN-DC (EN-direct current) of a serving cell and a frequency to be detected of 2350MHz, and supports NGEN-DC of the serving cell and the frequency to be detected of 850 MHz.

TABLE 3 frequency indication information

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

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

For example, when the dual connection supported by the terminal device is EN-DC, it is 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, the frequency to be measured 2350MHz is determined as the target frequency to be measured. The dual connection between the frequency under test 850MHz and the serving cell is NGEN-DC, unlike the dual connection supported by the terminal device, and thus the frequency under test 850MHz cannot be determined as the target frequency under test.

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

It should be noted that, the execution of step S404 may be referred to the specific description in step S204 in fig. 2, and will not be repeated here.

In the above embodiment, the terminal device obtains the frequency set, and obtains the frequency indication information, where the frequency indication information is used to indicate dual connections between each frequency to be tested and the serving cell of the terminal device; determining a target frequency to be detected from a plurality of frequencies to be detected in a frequency set according to the frequency indication information, wherein the double connection between the target frequency to be detected and a service cell is the same as the double connection supported by the terminal equipment; and the terminal equipment measures the cell on the target frequency to be measured. The measurement of frequencies (the frequency without measurement and the double connection between the service cells are different from the double connection supported by the terminal equipment) which are not needed to be measured can be avoided, and the power consumption of the terminal equipment can be reduced.

Referring to fig. 5, fig. 5 is a flowchart of another measurement method according to an embodiment of the present application, where the measurement method shown in fig. 5 may 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, a terminal device acquires a frequency set; the set of frequencies includes a plurality of frequencies to be measured.

It should be noted that, the execution of step S501 may be described in detail in step S201 in fig. 2, and will not be described here.

S502, the terminal equipment acquires frequency indication information; the frequency indication information is used for indicating the double connection between the cell on each frequency to be measured and the service cell of the terminal equipment.

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

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

TABLE 4 frequency indication information

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

Specifically, the terminal device may determine whether the dual connection between each cell and the serving cell on each frequency to be measured in the frequency set is the same as the dual connection supported by the terminal device. If there is at least one double connection between the cell and the service cell on the frequency to be measured, which is the same as the double connection supported by the terminal device, the frequency to be measured is determined as the target frequency to be measured.

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

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

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

S505, the terminal equipment measures the target cell.

It should be noted that, the execution of step S505 may be described in detail in step S204 in fig. 2, and will not be described here.

In the above embodiment, the terminal device obtains the frequency set, obtains the frequency indication information, determines the target to-be-measured frequency from the plurality of to-be-measured frequencies in the frequency set according to the frequency indication information, determines the target cell from the cells on the target to-be-measured frequency, 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 (the double connection between the cell which does not need to be measured and the service cell is different from the double connection supported by the terminal equipment) 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 equipment.

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

In one implementation manner, when the number of the cells which are measured by the terminal equipment and meet the reporting requirement is K and K is greater than the threshold value M, the measurement of other cells can be omitted, that is, the terminal equipment only needs to measure the strongest K NR cells which meet the reporting requirement, which is beneficial to reducing the cost brought by the measurement of the terminal equipment. Where the threshold M indicates that at most only M carriers can be supported by the NR SCG.

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

In one implementation, when the terminal device reports the measurement result to the base station, the measurement result of the Z cells and the corresponding cell physical identifier may be selected from the N NR cells that have been measured and reported. Optionally, in the reporting process, the first Z measurement results may be selected from the N measurement results in order from high to low. In this way, the signaling overhead of reporting is advantageously reduced. Wherein N is greater than Z. Z may be K as previously described, or Z may be greater than K.
