The network device provides a service for the terminal device through a cell or a transceiver in the cell, the terminal device communicates with the cell or a transceiver in the cell through a transmission resource (e.g., a frequency domain resource, or a spectrum resource, or a video resource) allocated by the network device, the cell may be a cell corresponding to the transceiver, the cell may belong to a macro base station (e.g., macro eNB or macro gNB), or may belong to a base station corresponding to a small cell (small cell), and the small cell herein may include: urban cell (metro cell), micro cell (microcell), pico cell (pico cell), femto cell (femto cell), etc., and these small cells have the characteristics of small coverage and low transmission power, and are suitable for providing high-rate data transmission service.

Fig. 1 shows a schematic diagram of a network architecture of dual connectivity, and as shown in fig. 1, a terminal device may simultaneously have a communication connection with two network devices and may transmit and receive data, which may be referred to as dual connectivity. One of the two network devices (e.g., base stations) may be mainly responsible for exchanging radio resource control messages with the terminal device and for exchanging with a core network control plane entity, so that the base station may be referred to as a master gbb (MgNB), and the other base station may be referred to as a secondary gbb (SgNB). The main base station is a control plane anchor point, that is, the terminal device establishes RRC connection with the main node, and the main base station establishes control plane connection with the core network. In the subsequent enhanced technology, part of RRC messages (e.g., measurement configuration information, measurement report, etc.) may also be sent between the secondary base station and the terminal device. In DC, a plurality of serving cells in a primary base station form a primary cell group (MCG), which includes a primary cell (PCell) and optionally one or more secondary cells (PCell). A plurality of serving cells in the secondary base station form a Secondary Cell Group (SCG), which includes a primary secondary cell (PSCell, or may also be referred to as a special cell) and optionally one or more scells. The serving cell is a cell configured by the network to the terminal device for uplink and downlink transmission.

Similarly, a terminal device may also have a communication connection with multiple network devices, such as base stations) and may transmit and receive data, which may be referred to as multi-connection or multi-connection (MC), where one of the multiple base stations may be responsible for exchanging radio resource control messages with the terminal device and for interacting with a core network control plane entity, and then this base station may be referred to as a primary base station, and the remaining base stations may be referred to as secondary base stations. It is understood that DC is a scenario for MC.

It should be understood that fig. 1 is a schematic diagram of one network architecture for DC. For the sake of understanding the present application, the following description continues with the architecture of carrier aggregation.

Carrier aggregation: to efficiently utilize the fragmented spectrum, the system supports aggregation between different carrier units. A technique of aggregating 2 or more than 2 carriers together to support a larger transmission bandwidth may be referred to as carrier aggregation.

In the carrier aggregation technology, a terminal device may configure a plurality of carrier elements (CCs, or referred to as component carriers, and the like), and each CC may correspond to an independent cell. One CC may be identical to one cell. For example, the primary cell corresponds to a primary CC (or referred to as a primary carrier), and may be a cell for performing initial connection establishment for a terminal, a cell for performing RRC connection reestablishment, or a primary cell designated in a handover (handover) process. The secondary cell corresponds to a secondary CC (or referred to as a secondary carrier), which may be a cell added during RRC reconfiguration to provide additional radio resources.

For a terminal device in a connected state, if carrier aggregation is configured, the terminal device may have multiple serving cells (serving cells), which may be referred to as a serving cell set. For example, the primary cell and the secondary cell described above constitute a serving cell (serving cell) set of the terminal device. In other words, in the scenario of configuring carrier aggregation, the serving cell set includes at least one primary cell and at least one secondary cell. In other words, a terminal device configured with carrier aggregation may perform data transmission with 1 PCell and multiple scells.

Fig. 2 is a schematic diagram of a system 100 to which the measurement method of the embodiment of the present application can be applied. As shown in fig. 2, the communication system 100 may include at least one terminal device, such as terminal device 101 shown in the figure; the communication system 100 may also include at least three network devices, such as

base stations

102, 103, 104 as shown.

In fig. 2, terminal apparatus 101 may be in communication connection (i.e., DC) with both

base stations

102 and 103 and may transmit and receive data, where terminal apparatus 101 may be in communication connection with base station 102 via multiple serving cells, and similarly, terminal apparatus 101 may be in communication connection with base station 103 via multiple serving cells. As a possibility, the base station 102 may serve as a main base station of the terminal apparatus 101, and a plurality of serving cells of the base station 102 constitute an MCG. The base station 103 may serve as a secondary base station of the terminal device 101, and a plurality of serving cells of the base station 103 constitute an SCG.

As terminal apparatus 101 moves toward base station 103 and gradually moves away from base station 102, terminal apparatus 101 faces the problem of reconfiguring serving cells (MCG and/or SCG) and serving base stations (primary base station and/or secondary base station).

For example, when the handover condition is satisfied, the terminal apparatus 101 may disconnect from the base station 102 and establish a communication connection with the base station 104. At this time, the base station 103 may be configured as a new master base station of the terminal apparatus 101, and a plurality of serving cells under the base station 103 may be configured as a new MCG, and further, the base station 104 may be configured as a new secondary base station, and a plurality of serving cells under the base station 104 may be configured as a new SCG.

In addition, with respect to fig. 2, there may be another case where the terminal device 101 resides in a serving cell of the base station 102 and is in a non-connected state (for example, an idle state, a deactivated state RRC _ INACTIVE, an enhanced idle state, or other non-connected states). As one possibility, the terminal apparatus 101 is switched to the connected state within the base station 102, or, as another possibility, the terminal apparatus 101 moves into the base station 103 and is switched to the connected state within the base station 103. After the terminal device 101 changes from the non-connected state to the connected state, the base station 102 and/or the base station 103 may send measurement configuration for the terminal device 101, and may configure carrier aggregation configuration or dual connectivity configuration for the terminal device 101 according to the measurement result reported by the terminal device 101.

The application provides a measurement method, which can reasonably perform measurement configuration, and a terminal device can perform measurement efficiently and report a measurement report quickly, so that when the terminal device is switched from a non-connection state to a connection state, or after the terminal device is switched to a new service base station, carrier aggregation configuration or dual-connection configuration can be configured for the terminal device in time.

Fig. 3 is a schematic flow diagram of a measurement method 200 according to the present application. The measurement method 200 of the present application is described in detail below with reference to fig. 3.

It is understood that, in the embodiments of the present application, a terminal device and/or a network device may perform some or all of the steps in the embodiments of the present application, and these steps or operations are merely examples, and the embodiments of the present application may also perform other operations or various modifications of the operations. Further, the various steps may be performed in a different order presented in the embodiments of the application, and not all operations in the embodiments of the application may be performed.

In step 210, the base station # a generates measurement configuration information indicating at least one frequency-domain resource group including at least one frequency-domain resource.

Specifically, the frequency-domain resource group may include frequency-domain resources for carrier aggregation, or the frequency-domain resource group includes frequency-domain resources for multi-connection, or the frequency-domain resource group may include frequency-domain resources for carrier aggregation and multi-connection.

The frequency domain resource may be at least one of a frequency point and a frequency band. The frequency resource group may be a frequency point combination composed of at least one frequency point, or the frequency resource group may be a frequency band combination composed of at least one frequency band, or the frequency resource group may be a frequency point frequency band combination composed of at least one frequency point and at least one frequency band.

In step 220, the base station # a transmits the measurement configuration information to the terminal apparatus.

Specifically, the measurement configuration information may be generated by the base station # a and transmitted to the terminal device.

Here, the base station # a may be a serving base station of the terminal device. Base station # a may be one serving base station unique to terminal apparatus # a, or may be one of a plurality of serving base stations.

For example, in a multi-connection scenario, base station # a may be the primary serving base station of the terminal device or may be the secondary base station of the terminal device.

For example, in a dual connectivity scenario, base station # a may be a primary base station of the terminal device, or base station # a may be a base station where a primary cell is located.

Alternatively, the base station # a may be a secondary base station of the terminal device, or the base station # a may be a base station where the primary and secondary cells are located.

Base station # a may generate the measurement configuration information from base station configuration information acquired from other base stations (e.g., base station # B). Base station # a may also transmit base station configuration information of base station # a to other base stations.

The base station configuration information may indicate frequency domain resource combinations supported by the base station for carrier aggregation, or include frequency domain resource combinations supported by the base station for multiple connections, or include frequency domain resource combinations supported by the base station for carrier aggregation and multiple connections.

Or, the base station configuration information may also be used to indicate frequency domain resource combination capability information supported by the base station for carrier aggregation, and/or frequency domain resource combination capability information supported by the base station for multiple connections, where the frequency domain resource combination capability information may be frequency point combination capability information or frequency band combination capability information.

Here, the base station # B may be a neighbor base station of the serving base station of the base station # a or the terminal apparatus. Alternatively, base station # B may be another serving base station for the terminal device.

Base station # a and other base stations (e.g., base station # B) may exchange corresponding base station configuration information through an X2/Xn interface setup request message (X2/Xn set request), an X2/Xn interface setup response message, radio access network node configuration update (ng-node configuration update or eNB configuration update) information, radio access network configuration acknowledgement (ng-node configuration acknowledgement or eNB configuration acknowledgement) information, secondary node addition request (s-node addition request or seNB addition request) message or secondary node addition request acknowledgement (s-node addition request acknowledgement or seNB addition request acknowledgement) message, and the like. For example, when the base station # a sends an Xn interface establishment request message to another base station, the Xn interface establishment request message carries the base station configuration information of the base station # a; other base stations can send Xn interface establishment response messages, and the Xn interface establishment response messages carry the base station configuration information of the base stations.

Specifically, the base station # a may determine at least one frequency-domain resource group in the measurement configuration information according to the base station configuration information of itself and/or other base stations.

For example, the base station may determine the at least one frequency-domain resource group according to the frequency point combining capability or the frequency band combining capability of the carrier aggregation supported by itself and/or other base stations.

For example, in step 201, the base station # B may transmit its own base station configuration information to the base station # a, and the base station # a may determine at least one frequency-domain resource group according to its own base station configuration information and the base station # B configuration information.

The base station configuration information includes a frequency domain resource combination, and the frequency domain resource combination is exemplified as the frequency point combination. It can be understood that the embodiment of the present application is also applicable to a scenario in which frequency domain resources are combined into a frequency band combination, and also applicable to a scenario in which the base station configuration information includes a frequency domain resource combination capability, which is not limited in the embodiment of the present application. The frequency point combination of carrier aggregation supported by the base station # A comprises { F1, F2}, { F1, F3}, the base station configuration information of the base station # B comprises frequency point combinations supported by the base station # B for carrier aggregation comprising { F2, F3}, { F2, F4}, the frequency point combination supported by the base station # A for multi-connection comprises { F1, F5}, { F1, F6}, and the base station configuration information of the base station # B comprises frequency point combinations supported by the base station # B for multi-connection comprising { F2, F5}, { F2, F7 }.

Therefore, in step 210, the base station # a may generate at least one frequency-domain resource group by at least one of:

(1) determining a frequency domain resource group #1-1 according to the frequency point combination for carrier aggregation supported by the base station # A: { F1, F2, F3 };

(2) determining a frequency domain resource group #1-2 according to the frequency point combination for carrier aggregation supported by the base station # B: { F2, F3, F4 };

(3) determining a frequency domain resource group #1-3 according to the frequency point combination for carrier aggregation supported by the base station # A and the base station # B: { F1, F2, F3, F4 };

(4) determining a frequency domain resource group #2-1 according to the frequency point combination for multi-connection supported by the base station # A: { F1, F5, F6 };

(5) determining a frequency domain resource group #2-2 according to the frequency point combination for multi-connection supported by the base station # B: { F2, F5, F7 };

(6) determining a frequency domain resource group #2-3 according to the frequency point combination for multi-connection supported by the base station # A and the base station # B: { F1, F2, F5, F6, F7 };

it should be understood that the foregoing manners are merely examples, and corresponding frequency resource groups may also be generated according to partial combinations in corresponding types of frequency point combinations, which is not limited in this application.

Those skilled in the art will appreciate that the above various ways are only one example of determining the measurement configuration information according to the base station configuration information of the base station # a and the other base stations (base station # B), and the present application is not limited thereto. The above various manners are described by taking the frequency domain resource supported by the base station as the frequency point as an example, and the types of the frequency domain resource supported by the base station are not limited in the present application.

The at least one frequency-domain resource group includes a first frequency-domain resource group including frequency-domain resources for carrier aggregation or multi-connection with the first frequency-domain resources. As a possible implementation, the first set of frequency-domain resources may correspond to the first frequency-domain resources. Alternatively, the first set of frequency-domain resources includes the first frequency-domain resource.

In particular, the first set of frequency-domain resources may correspond to a first set of frequency-domain resources, wherein the first set of frequency-domain resources may be included within the first set of frequency-domain resources. Any frequency-domain resource within the first set of frequency-domain resources may be referred to as a first frequency-domain resource, or a first-ordered frequency-domain resource within the first set of frequency-domain resources is referred to as a first frequency-domain resource. Other frequency-domain resources within the first set of frequency-domain resources (i.e., some or all of the frequency-domain resources within the set other than the first frequency-domain resource) may be carrier aggregated or multi-connected with the first frequency-domain resource.

For example, taking frequency resource group #1-1 as an example, the frequency resource group #1-1 corresponds to frequency point F1, and the frequency resource group #1-1 includes frequency points F2 and F3 for carrier aggregation with the frequency point F1. That is, the frequency resource group #1-1 is a first frequency resource group in at least one frequency resource group, frequency point F1 is a first frequency resource corresponding to the first frequency resource group, and frequency points F2 and F3 are frequency resources used for carrier aggregation with the first frequency resource group.

For another example, taking frequency resource group #1-2 as an example, frequency resource group #1-2 may correspond to frequency point F1, and frequency resource group #1-1 includes frequency points F2 and F3 for carrier aggregation with frequency point F1. That is, the frequency resource group #1-1 is a first frequency resource group in at least one frequency resource group, frequency point F1 is a first frequency resource corresponding to the first frequency resource group, and frequency points F2 and F3 are frequency resources used for carrier aggregation with the first frequency resource group. Frequency resource group #1-2 may also correspond to frequency point F2, with frequency resource group #1-2 including frequency points F3, F4 for carrier aggregation with frequency point F2.

Optionally, the frequency domain resource may comprise a frequency domain resource used by a serving cell of the terminal device.

For example, the frequency domain resources may include frequency domain resources used by a primary cell of the terminal device, or the frequency domain resources may include frequency domain resources used by a secondary cell of the terminal device, or the frequency domain resources may include frequency domain resources used by a primary and secondary cell of the terminal device.

Or, the frequency domain resource may include a frequency domain resource used by a serving cell in an MCG or an SCG of the terminal device.

Alternatively, the frequency domain resources may comprise frequency domain resources used by a serving cell of the set of serving cells of the terminal device.

In addition, the frequency domain resource may not include a frequency domain resource used by a serving cell of the terminal device.

In step 230, the terminal device receives the measurement configuration information and performs measurement according to the measurement configuration information.

Specifically, the terminal device measures frequency domain resources in the frequency domain resource group according to the at least one frequency domain resource group indicated by the measurement configuration information.

Alternatively, the terminal device may make measurements for each frequency-domain resource within each group of frequency-domain resources.

For example, the terminal device may measure each frequency-domain resource in each frequency-domain resource group, and obtain a measurement result of one or more cells under the frequency-domain resource. Specifically, the measurement result may be any one or more parameters of Reference Signal Receiving Power (RSRP), Signal Noise Ratio (SNR), Received Signal Strength Indication (RSSI), Reference Signal Receiving Quality (RSRQ), and the like of the cell.

Alternatively, the terminal device may not measure all frequency-domain resources within each frequency-domain resource group.

For example, for a first frequency-domain resource group, a first frequency-domain resource corresponding to the first frequency-domain resource group may be measured, and whether to measure other frequency-domain resources in the first frequency-domain resource group may be determined according to a measurement result of the first frequency-domain resource. Or, the first frequency-domain resource corresponding to the first frequency-domain resource group may be measured first, and whether to measure the frequency-domain resource that is subjected to carrier aggregation or multi-connection with the first frequency-domain resource may be determined according to the measurement result of the first frequency-domain resource.

Specifically, the other frequency domain resources in the first frequency domain resource group may be measured only when the measurement result of the cell corresponding to the first frequency domain resource meets a certain condition. For example, when the terminal device measures the first frequency domain resource, if the measurement result of the at least one cell corresponding to the first frequency domain resource measured by the terminal device is greater than or equal to the preset first threshold, the other frequency domain resources in the first frequency domain resource group are measured.

Or, when the terminal device measures the first frequency-domain resource, if the terminal device cannot search for or cannot measure the cell corresponding to the first frequency-domain resource, or if the terminal device measures that the quality of all the cells corresponding to the first frequency-domain resource is lower than the second threshold, the terminal device may not measure other frequency-domain resources in the first frequency-domain resource group. It is understood that the first threshold and the second threshold may be the same or different, or the second threshold and the first threshold may be the same threshold.

The first threshold and the second threshold may be arbitrarily determined by the terminal device, may be defined by the communication system or the communication protocol, or may be configured by the network device, and the present application is not particularly limited.

Taking the terminal device to obtain the first threshold as an example, the first threshold may be configured by the serving base station of the terminal device, for example, the first threshold may be included in the measurement configuration information.

The terminal device may determine at least one target frequency domain resource from a second frequency domain resource group, where the target frequency domain resource is a frequency domain resource that the terminal device can support, and the second frequency domain resource group is any one of the at least one frequency domain resource group; and the terminal equipment measures the target frequency domain resource.

For example, the at least one target frequency domain resource may be determined according to the support capability information of the terminal device.

Optionally, the terminal device may determine whether to measure the frequency-domain resource group or determine whether to measure the frequency-domain resources in the frequency-domain resource group according to its own support capability information. The support capability information of the terminal device may indicate frequency domain resource combinations (e.g., frequency point combinations or frequency band combinations) that the terminal device can support for carrier aggregation and/or multi-connectivity. The terminal device may select a corresponding frequency-domain resource group or select a corresponding frequency-domain resource in the frequency-domain resource group for measurement according to frequency point combination capability information or frequency band combination capability information for carrier aggregation and/or multi-connection supported by the terminal device.

For example, taking the above-mentioned frequency resource group #1-1 as an example, if the terminal device supports frequency points F1 and F2 in the group, for example, the terminal supports configuration F1 and F2 for carrier aggregation configuration of the terminal device, but does not support frequency point F3 in the group, then no measurement may be performed on frequency point F3. For frequency resource group #2-1, if the terminal device supports frequency points F1 and F5 in the group, for example, the terminal supports configuration F1 and F5 for multi-connection configuration of the terminal device, but does not support frequency point F6 in the group, then no measurement may be performed on frequency point F6. Further, if the measurement result of any cell corresponding to F1 measured by the terminal device does not satisfy the first threshold, the terminal device may not measure F2 and F5.

Alternatively, when there are multiple frequency-domain resource groups (i.e., there are at least two frequency-domain resource groups), the terminal device may measure the multiple frequency-domain resource groups in a certain order. As one implementation, the terminal device may determine a priority of each frequency-domain resource group, and measure the frequency-domain resources in the frequency-domain resource group in order of the priority. Specifically, the priority may be determined by the support capability information of the terminal device. For example, the terminal device may determine a priority of each frequency-domain resource group according to the support capability information of the terminal device, and measure the frequency-domain resources in the frequency-domain resource group in order of the priority. As another implementation, the priority may be configured by the base station. For example, the base station may be determined according to base station configuration information of the base station. The base station may determine a priority of each frequency-domain resource group according to the frequency-domain resource combination for carrier aggregation and/or multi-connectivity supported by the base station, and send the priority indication information to instruct the terminal device to measure the frequency-domain resources in the frequency-domain resource groups in the measurement configuration information according to the priority. Taking the frequency-domain resource group #1-1 and the frequency-domain resource group #1-2 as examples, the base station # a may send priority indication information to the terminal device, where the priority indication information is used to indicate that the frequency-domain resource group 1-1 has a high priority and the frequency-domain resource group 1-2 has a low priority; and/or, taking the frequency-domain resource group #2-1 and the frequency-domain resource group #2-2 as an example, the priority indication information is used to indicate that the frequency-domain resource group #2-1 has a high priority and the frequency-domain resource group #2-2 has a low priority. The priority indication information may be carried in measurement configuration information. After receiving the measurement configuration information, the terminal device can determine the priority of each frequency-domain resource group, and measure the frequency-domain resources in the frequency-domain resource group according to the order of the priority.

The measurement configuration information may further include measurement reporting configuration, for example, at least one of the following information: the number of frequencies reported at most, the number of cells reported at most, the number of beams (beam) reported at most by each cell, whether to report a Cell Global Identifier (CGI), and the like.

In step 240, the terminal apparatus transmits a measurement report to base station # a.

Alternatively, the terminal device transmits the measurement report to other base stations (such as base station # B). Such as a terminal device reselecting from a cell under base station # a to a cell under base station # B, the terminal device may send a measurement report to base station # B when the terminal device initiates access in a new cell.

The measurement report includes measurement results of measuring the frequency domain resources. The measurements may be cell-level or, alternatively, measurements for different cells at various frequency domain resources. Optionally, the measurement result may further include a measurement result of at least one beam under the cell.

Optionally, the terminal device may report the measurement results of different frequency-domain resource groups according to the priority of the frequency-domain resource group.

Optionally, in step 250, the base station # a receives the measurement report and makes a decision according to the measurement report.

Alternatively, base station # B receives the measurement report and makes a decision based on the measurement report.

For example, base station # a (or base station # B) may determine whether to configure carrier aggregation or multi-connection for the terminal device according to the measurement result in the measurement report, or determine whether to configure a new serving cell and/or serving base station for the terminal device.

Optionally, the method further comprises:

in step 260, base station # a transmits the measurement result of the terminal apparatus to base station # B.

The base station # a may also forward the partial or all measurement results to other serving base stations (e.g., base station # B) of the terminal device, and the base station # B determines whether to configure carrier aggregation or multi-connection for the terminal device, which is not limited in this application. For example, the base station # a determines to perform handover according to the measurement result, and the base station # a may transmit the measurement result or a part of the measurement result (for example, the base station # a selects a suitable measurement result according to the base station configuration information of the base station # B) to the target base station (i.e., the base station # B) corresponding to the target cell. Base station # B may determine whether to configure carrier aggregation or multi-connection for the terminal device based on the measurement result.

According to the measurement method, the base station can reasonably configure the measurement target for the terminal equipment, the measurement efficiency of the terminal equipment can be improved, the terminal equipment can report the measurement report in time, when the terminal equipment is switched from a non-connection state to a connection state or when the terminal equipment switches the service base station, carrier aggregation or multi-connection can be configured in time, and the data transmission experience of the terminal equipment is improved.

Fig. 4 is a schematic flow chart of a measurement method 300 according to the present application. The measurement method 300 of the present application is described in detail below with reference to fig. 4.

In step 310, the terminal device determines a plurality of measurement GAPs GAP, where the lengths of any two measurement GAPs in the plurality of measurement GAPs are not the same. The length of the measurement GAP may be understood as the length of time the terminal is used to perform the measurement. For example, the GAP may be 3ms or 6ms long every 40ms, i.e. 3ms or 6ms for every 40ms is used for performing the measurement. It may be said at this time that the lengths of the two measurement GAPs are not the same.

Specifically, a plurality of measurement GAPs GAP may be determined according to previous measurement experience, and the plurality of measurement GAPs may be determined according to the number of frequency points (or carrier frequencies) to be measured, where different frequency points correspond to different measurement GAPs, and the longer the measurement GAP is, the more the number of frequency points may be. A plurality of measurement GAPs with different lengths can be determined according to the corresponding relation between the measurement GAP and the frequency point number in the previous measurement.

It should be understood that the plurality of measurement GAPs may be determined by the terminal device, may be defined by the communication system or the communication protocol, or may be configured by the network device, and the present application is not particularly limited.

It should be understood that the number of frequency points to be measured may also be equivalent to the number of frequency bands to be measured or the number of cells.

In step 320, the terminal device determines a second measurement GAP from the plurality of measurement GAPs according to the number of frequency points of the second frequency point group to be measured.

The frequency domain resources are taken as the frequency points as an example in the embodiment of the present application, and it can be understood that the embodiment of the present application does not limit this, for example, the embodiment of the present application can also be applied to a scenario in which the frequency domain resources are frequency bands.

In step 330, the terminal device measures the frequency points in the second frequency point group according to the second measurement GAP.

Specifically, the second measurement GAP may be determined from the plurality of measurement GAPs according to the number of frequency bin groups to be measured, according to previous measurement experience. The basic principle of the determination is to ensure that all frequency points of the second frequency point group can be exactly measured within the GAP length. The terminal device may measure each frequency point in the second frequency point group according to the second measurement GAP.

The mechanism for determining the number of frequency points to be measured by the terminal device may refer to the relevant mechanism in step 230, which is not described herein again.

Optionally, in step 320, the method may further include:

the terminal device determines a second measurement GAP from the multiple measurement GAPs according to the relationship between the number of the second frequency point groups and the number of the first frequency point groups and the first measurement GAP, wherein the first frequency point group is a frequency point group measured before the second frequency point group, and the first measurement GAP is a measurement GAP used when the terminal device measures the first frequency point group. The first measurement GAP is the measurement GAP used by the terminal device before determining the second measurement GAP.

Specifically, referring to the foregoing method 200, the number of frequency points measured by the terminal device at each time may be different (e.g., increased or decreased), or may be the same. The terminal equipment can determine the GAP length used in the measurement according to the change condition of the frequency point number on the basis of the previous measurement.

The terminal device measures the frequency points in the first frequency point group according to the first measurement GAP, and then the terminal device needs to measure the frequency points in the second frequency point group, and can determine the second measurement GAP according to the size relationship of the number of the frequency points measured twice and the first measurement GAP.

For example, if the number of bins in the second bin group is greater than the number of bins in the first bin group (for example, the difference between the two is equal to a certain threshold), a second measurement GAP may be determined from the multiple measurement GAPs, and the length of the second measurement GAP is greater than that of the first measurement GAP.

For another example, if the number of bins in the second bin group is equal to the number of the first bin group, the length of the second measurement GAP may be equal to the length of the first measurement GAP. In other words, the terminal device continues to use the first measurement GAP.

For another example, if the number of bins in the first bin group is greater than the number of bins in the second bin group (for example, the difference between the two numbers reaches a certain threshold), a second measurement GAP may be determined from the multiple measurement GAPs, and the length of the second measurement GAP is smaller than that of the first measurement GAP.

Optionally, when the length of the second measurement GAP is not equal to the length of the first measurement GAP, the method 300 further includes:

and the terminal equipment sends notification information to the base station, wherein the notification information is used for notifying that the measurement GAP currently used by the terminal equipment is the second measurement GAP.

For example, the terminal device may send a special random access preamble to the network device. The random access preamble corresponds to the second measurement GAP, and the correspondence between the random access preamble and the second measurement GAP may be received by the terminal device from the network device. The network device receives the random access preamble, and may determine that the measurement GAP of the terminal device is updated to the second measurement GAP.

When the measurement GAP is changed, the base station side can be timely notified, and the base station can timely adjust data scheduling of the terminal equipment according to the notification information, so that the problem that the terminal equipment cannot receive data when the short measurement GAP is updated to the long measurement GAP to cause network resource waste is solved, or the problem that the network equipment does not schedule data when the terminal equipment is updated to the short measurement GAP from the long measurement GAP is solved, and the utilization rate of network resources is improved.

Optionally, the method 300 further comprises:

the terminal equipment determines a third measurement GAP from the plurality of measurement GAPs according to the completion condition of the second measurement GAP for measuring the frequency points in the second frequency point group;

and the terminal equipment measures the frequency points in the second frequency point group according to the third measurement GAP.

Specifically, the terminal device determines a second measurement GAP according to the number of frequency points in a second frequency point group, and performs measurement according to the second measurement GAP, and if the configuration of the second measurement GAP is not reasonable (for example, all frequency points in the group are not measured completely in the GAP), fine adjustment should be performed according to the completion condition of measurement in the next measurement, or a new and reasonable measurement GAP is reselected.

For example, the terminal device performs measurement according to the second measurement GAP, but the measurement of all the frequency points in the second frequency point group is not completed in the GAP, and then a GAP with a longer length may be reselected from the multiple GAPs according to a completion condition (for example, a completed percentage).

For another example, the terminal device performs measurement according to the second measurement GAP, and completes measurement of all frequency points in the second frequency point group earlier in the GAP, for example, the measurement time corresponding to the GAP is 6ms, and the terminal device completes measurement of all frequency points within 3ms, and then may reselect a GAP with a shorter length from among the multiple GAPs according to a completion condition (for example, the measurement time occupies the percentage of the second measurement GAP).
