Description

Measurement method and communication device

Technical Field

The present application relates to the field of mobile communication technology, and more particularly, to a method of measurement and a communication apparatus.

Background

In order to improve the spectrum efficiency and the user throughput of the system, a Carrier Aggregation (CA) technology and a Dual Connectivity (DC) technology are introduced. The CA technology supports a terminal device to simultaneously use different carriers of multiple cells (cells) under the same base station for uplink and downlink communication, thereby supporting high-speed data transmission. The DC technology supports the terminal device to use the carriers of multiple cells of two different base stations for uplink and downlink communication at the same time.

In the DC and CA technologies, a terminal device needs to measure a current serving cell and a neighboring cell, and report a measurement result to a base station, so that the base station can configure a multi-carrier for the terminal device. In order to be able to configure the terminal device with CA or DC quickly, a mechanism is currently considered that allows the terminal device to report the measurement result earlier. However, the current measurement method is not perfect in the processing between the measurement performed by the terminal device and the power saving of the terminal device.

Disclosure of Invention

The application provides a cell measurement method and a communication device, which can help a terminal device to measure a target cell in time, reduce the measurement energy consumption of the terminal device and prolong the standby time of the terminal device.

In a first aspect, a method for measurement is provided, which may be performed by a terminal device, or may be performed by a chip configured in the terminal device. Specifically, the method comprises the following steps: the terminal equipment in the first cell measures the second cell to obtain a first measurement value; the terminal equipment determines whether to stop the measurement of the second cell according to the first measurement value.

According to the embodiment of the application, the measurement of the second cell is controlled by the obtained measurement result of the second cell, so that the measurement method of the second cell is more flexible and efficient. Specifically, whether to stop the measurement of the second cell may be determined according to the measurement result (for example, the measurement may be suspended for a period of time), so that the measurement energy consumption of the terminal device may be reduced, and the standby time of the terminal device may be prolonged.

With reference to the first aspect, in certain implementations of the first aspect, the determining whether to stop measuring the second cell includes: the terminal equipment determines to stop measuring the second cell; the method further comprises the following steps:

the terminal equipment starts a timer; during the timer running time, the terminal device stops measuring the second cell.

According to the embodiment of the application, the timer can be started after the terminal equipment stops measuring the second cell, the timer is used for indicating the duration for stopping measuring the second cell, the second cell can be continuously measured after the timer expires, discontinuous measurement of the second cell is achieved (so that energy is saved), the terminal equipment can start measurement of the second cell earlier, and therefore the second cell can be measured as soon as possible.

With reference to the first aspect, in some implementations of the first aspect, the determining, by the terminal device, whether to stop measuring the second cell according to the first measurement value includes: and stopping the measurement of the second cell when the first measurement value is less than or equal to a preset first threshold value.

The first measurement value may be one of the one or more measurement values, or may be a reference value obtained by performing a mathematical operation on one or more measurement values, for example, the first measurement value may also refer to an average value of a plurality of first measurement values.

For example, the first measurement value may be a signal quality value, and when the first measurement value is smaller than or equal to a preset first threshold, it indicates that the signal of the second cell is poor at this time, and the measurement of the second cell may be stopped in time, so that the measurement energy consumption of the terminal device may be reduced.

and stopping the measurement of the second cell when the difference value between the two first measurement values is less than or equal to a preset second threshold value.

For example, the first measurement value may be a signal quality value, and according to the measurement sequence, a difference between a subsequent first measurement value and a previous first measurement value is less than or equal to a preset second threshold, which indicates that the signal quality may be deteriorating at this time, or the signal quality may be improving, but the improving speed is slow, and the measurement on the second cell may be stopped at this time, so that the measurement energy consumption of the terminal device may be reduced.

For example, the influence of the signal quality of the currently located first cell on the measurement of the second cell that the terminal device may have on the second cell may be considered. For example, when the signal quality of the first cell is poor, or when it is rapidly degraded, the measurement of the second cell may not be stopped. For example, the measurement of the second cell may be resumed from the stopped state, or the measurement of the second cell may be restarted.

With reference to the first aspect, in certain implementations of the first aspect, the method further includes: the terminal equipment determines whether to increase the time interval between two adjacent measurements of the second cell according to the first measurement value. According to the embodiment of the application, whether the measurement time interval is increased or not can be judged according to the measurement result, so that the number of times of measurement in unit time is reduced, and the measurement energy consumption of the terminal equipment on the second cell can be further reduced.

In a second aspect, a method for measuring is provided, which may be performed by a terminal device, or may be performed by a chip configured in the terminal device. Specifically, the method comprises the following steps: the terminal equipment in the first cell measures the second cell by using the first time interval to obtain a first measured value; the terminal equipment determines whether to increase the time interval between two adjacent measurements of the second cell according to the first measurement value.

According to the method and the device, the measurement of the second cell is controlled through the obtained measurement result of the second cell, so that the measurement method of the second cell is more flexible and efficient. Specifically, whether to increase the time interval between two adjacent measurements of the second cell (or to extend the measurement period) may be determined according to the measurement result, so that the number of measurements in a unit time may be reduced, the measurement energy consumption of the terminal device may be reduced, and the standby time of the terminal device may be extended.

The technical solution in the present application will be described below with reference to the accompanying drawings.

For the understanding of the embodiments of the present application, a communication system suitable for the method provided by the embodiments of the present application will be described with reference to fig. 1. Fig. 1 shows a schematic diagram of a communication system 100 suitable for use in the method provided by the embodiments of the present application.

As shown in fig. 1, the communication system 100 may include at least one network device, such as a base station 1 shown in fig. 1 (e.g., may be a base station in a 5G system, a gNB); the communication system 100 may further comprise at least one terminal device, such as the terminal device 1 shown in fig. 1. The network device and the terminal device can communicate through a wireless link. For example, the base station 1 and the terminal device 1 in fig. 1 communicate via radio resources provided by the cell 1, thereby implementing uplink and downlink transmission of data between the two. Thus, the base station 1 and the terminal apparatus 1 in fig. 1 constitute a communication system.

In the embodiment of the present invention, the communication system 100 may be various communication systems, such as: examples of such systems include a global system for mobile communications (GSM) system, a Code Division Multiple Access (CDMA) system, a Wideband Code Division Multiple Access (WCDMA) system, a General Packet Radio Service (GPRS), a long term evolution (long term evolution, LTE) system, a Frequency Division Duplex (FDD) system, a Time Division Duplex (TDD) LTE system, a Universal Mobile Telecommunications System (UMTS), a Worldwide Interoperability for Microwave Access (WiMAX) communication system, a future fifth generation (5G) system, and a new radio NR (radio) system.

Furthermore, the method may be executed by the terminal device, or may be executed by a chip configured in the terminal device, for example, may be executed by the terminal device 1 in fig. 1, or may be executed by a chip configured in the terminal device 1.

For example, other scenarios include measurements performed by the terminal device to handover to a new serving cell, measurements performed by the terminal device to reselect to a new serving cell, and so on.

In other words, the measurement target of the measurement method provided by the present application may be a measurement target in the multi-carrier configuration information, a measurement target in the serving cell reselection configuration information, or another measurement target. That is, the measurement of the terminal device on the target cell may be at least one of intra-frequency measurement, inter-frequency measurement, and inter-system measurement.

In the embodiment of the present application, a terminal device and/or a network device may perform some or all of the steps in the embodiment of the present application, and these steps or operations are merely examples, and the embodiment of the present application may also perform other operations or variations of various 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.

As shown in fig. 2, a measurement method provided in an embodiment of the present application includes the following steps:

s201, the terminal equipment measures a second cell to obtain a first measured value;

the first measurement value may be a measurement result of signal quality for the second cell. The terminal device may further send the identification information of the second cell to a network device. The Signal quality measurement result may include 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.

Optionally, the first measurement value may also be a measurement result for at least one beam, and the terminal device may further send identification information of the at least one beam to the network device. Optionally, the identification information of the second cell may be identification information of a cell whose signal quality satisfies a first preset condition, and the identification information of the at least one beam may be identification information of a beam whose signal quality satisfies a second preset condition, or identification information of all beams belonging to the cell. The first preset condition and the second preset condition may be configured by a network device or predefined, and this is not limited in this embodiment of the present application. The first measurement value in the embodiment of the present application may also be referred to as a signal quality measurement report or a signal quality measurement result by other names.

Optionally, the measuring, by the terminal device, the second cell includes performing at least one of the following measurement types on the second cell: the method comprises the steps that the terminal equipment measures at least one first frequency point, the terminal equipment measures at least one different system, the terminal equipment measures at least one second cell under the at least one first frequency point, and the terminal equipment measures at least one second cell under the at least one different system. The first frequency point may be the same (same frequency) as or different (different frequency) from a frequency point to which a current serving cell of the terminal device (i.e., a first cell in which the terminal device is located), i.e., the first cell is the current serving cell of the terminal device, and the terminal device resides in and/or accesses the first cell) belongs. The first measurement value may include a signal quality measurement result of the second cell corresponding to the at least one measurement type. Specifically, the terminal device may measure at least one first frequency point, and obtain a first measurement value of at least one second cell under the at least one first frequency point; or, the terminal device may measure at least one inter-system, and obtain a first measurement value of at least one second cell under the at least one inter-system; or the terminal equipment measures at least one second cell under at least one first frequency point to obtain a first measurement value of the at least one second cell; or the terminal device measures at least one second cell under at least one different system, and obtains a first measurement value of the at least one second cell.

S202, the terminal device determines whether to stop the measurement of the second cell or whether to increase the time interval between the measurements of the second cell according to the first measurement value. .

Optionally, the time interval between two measurements may also be referred to as a measurement period.

The terminal device determining whether to stop the measurement of the second cell may be determining whether to stop the measurement of the corresponding measurement type in S201. For example, if the measurement performed in S201 is at least one first frequency point, that is, the measurement is at a frequency point level, the terminal device determines whether to stop the measurement of the first frequency point; alternatively, the determination by the terminal device whether to increase the measurement period for the second cell may be the determination by the terminal device whether to increase the measurement period for the measurement type in S201. For example, if the measurement performed in S201 is performed in at least one first frequency point, that is, the measurement is on a frequency point level, the terminal device determines whether to increase the measurement period for the first frequency point.

As an implementation manner, the terminal device determines whether to stop the measurement on the second cell according to the first measurement value, which may be that the terminal device determines whether to stop the measurement on the second cell according to the first measurement value and a first threshold. Specifically, if the first measurement value is smaller than or equal to the first threshold, the terminal device stops measuring the second cell. As an implementation manner, the terminal device starts a timer, and during the running time of the timer, the terminal device stops the measurement of the second cell. And if the first measurement value is larger than the first threshold value threshold, the terminal equipment does not stop measuring the second cell.

As an implementation manner, the terminal device determines whether to increase the measurement period of the second cell according to the first measurement value, which may be that the terminal device determines whether to increase the measurement period of the second cell according to the first measurement value and a second threshold. Specifically, the terminal device may determine whether to increase the measurement period for the second cell according to a quality difference value between the first measurement value and the reference measurement value and a second threshold. Specifically, if the quality difference is smaller than or equal to a second threshold, the terminal device determines to increase a measurement period of the second cell; and if the quality difference is larger than the second threshold, the terminal equipment does not increase the measurement period of the second cell. The first measurement value may be a latest measurement value of the second cell measured by the terminal device, and the reference measurement value may be a measurement value of the second cell measured last time by the terminal device, or determined according to the measurement value of the second cell measured M times before by the terminal device. For example, the reference measurement value may be a linear average of the measurement values of the second cell measured in the previous M times, or a measurement value determined according to the measurement values of the second cell measured in the previous M times and the corresponding weighting coefficients. In a specific embodiment, if the measurement period configured by the current terminal device is 10ms, the measurement type is to measure at least one second cell under at least one second frequency point, that is, the terminal device measures the second cell every 10 ms. If the terminal device determines to increase the measurement period of the second cell according to the first measurement value, the terminal device may measure the second cell every 20ms or other N × 10 ms. Wherein N may be an integer greater than or equal to 2.

Any one or more of the timer duration, the first threshold, the second threshold, M, and the weighting coefficient may be configured by the network device, or may be predefined, which is not limited in this embodiment of the present application.

Optionally, S203, the terminal device measures the first cell to obtain a second measurement value.

The first cell is a current serving cell of the terminal device. As an implementation manner, the terminal device performs periodic measurement on the first cell, and obtains a corresponding second measurement value. The terms "first" and "second" in the embodiment of the present invention are only used to distinguish similar objects (such as measured values), and therefore, for the description of the second measured value, reference may be made to the description of the first measured value in S201.

Optionally, S204, the terminal device determines whether to stop the measurement of the second cell or whether to increase the time interval between the measurements of the second cell according to the second measurement value. .

Optionally, the time interval between two measurements may also be referred to as a measurement period. As an implementation manner, if the terminal device determines to stop the measurement on the second cell in S202, the terminal device starts a timer, and during the running time of the timer, the terminal device may further determine whether to stop the timer according to the second measurement value. I.e. the terminal device may further determine whether to initiate measurements on the second cell based on the second measurement value. Specifically, if the second measurement value is lower than the third threshold, the terminal device stops the timer and starts measurement of the second cell; or if the second measurement value is higher than the third threshold, the timer continues to run, and the terminal device stops measuring the second cell;

as another implementation manner, if the terminal device determines to increase the measurement period of the second cell in S202, before the increased measurement period expires, the terminal device may determine whether to resume the measurement period of the second cell according to the second measurement value. Specifically, if the second measurement value is lower than the third threshold, the terminal device recovers the measurement period of the second cell. Or if the second measurement value is higher than the third threshold, the terminal device keeps increasing the measurement period of the second cell.

The third threshold may be configured by the network device or predefined, which is not limited in this embodiment of the present application.

Optionally, as another implementation manner, before step S202, the terminal device may perform S203 and S204; alternatively, before step S202, the terminal device simultaneously executes steps S201, S203, and S204. Specifically, the terminal device determines whether to stop measurement of the second cell or whether to increase a measurement period of the second cell based on the first measurement value and the second measurement value. For example, when the first measurement value is lower than the first threshold and the second measurement value is higher than the third threshold, the terminal device may stop the measurement of the second cell; alternatively, when the first measurement value is lower than the second threshold and the second measurement value is higher than the third threshold, the terminal device may increase the measurement period for the second cell.

The implementation manners in the present embodiment may be executed individually or in combination. As a combined implementation manner, the terminal device may first determine whether to stop the measurement of the second cell or whether to increase the measurement period of the second cell according to the first measurement value and the second measurement value; if the terminal device determines to stop the measurement of the second cell, the terminal device starts a timer, and during the running time of the timer, the terminal device may further determine whether to stop the timer according to the latest measurement value of the first cell. Alternatively, if the terminal device determines to increase the measurement period of the second cell, before the increased measurement period expires, the terminal device may determine whether to resume the measurement period of the second cell according to the latest measurement value of the first cell.

The following will describe the communication method provided in the embodiment of the present application by taking the second cell as cell # B as an example, with reference to fig. 3.

It should be noted that, in the following embodiments of the present application, names of messages between network elements or names of parameters in messages are only an example, and other names may also be used in a specific implementation, which is not specifically limited in this embodiment of the present application.

Fig. 3 is a schematic flowchart of another example of the method for cell measurement according to the present application. Hereinafter, a method for cell measurement provided in an embodiment of the present application is described in detail with reference to fig. 3.

Fig. 3 shows a measurement procedure of the terminal apparatus # a for the cell # B (e.g., the second cell).

Here, the terminal apparatus # a is in a cell # a, that is, the terminal apparatus # a is in a coverage area of the cell # a, or the terminal apparatus # a resides in the cell # a (for example, a first cell), or the cell # a is a serving cell of the terminal apparatus # a, or the terminal apparatus # a performs wireless communication through a wireless resource provided by the cell # a.

The cell # B may be a non-camping cell of the terminal apparatus # a, or the cell # B and the cell # a are different cells, for example, the cell # B may be a neighbor cell of the cell # a.

The cell # B may be a camped cell of the terminal apparatus # a, that is, the cell # B may be the same cell as the cell # a.

As shown in fig. 3, the terminal apparatus # a can perform measurement on cell # B.

The terminal apparatus # a measures the cell # B based on the received measurement target, which may be the cell # B or the frequency point # B where the cell # B is located. Alternatively, the measurement of the cell # B by the terminal apparatus # a may be that the terminal apparatus # a measures the frequency point # B, and further, measures the cell # B under the frequency point # B, where the frequency point # B is the frequency point where the cell # B is located.

By way of example and not limitation, the measurement may be performed periodically, where a period of the measurement (e.g., a starting time of the period or a length of the period) may be specified by a communication system or a communication protocol, or may be configured by a network device (e.g., an access device of cell # a or cell # B), and the present application is not particularly limited.

Note that, in the present application, the timing at which the terminal apparatus # a can measure the cell # B may be arbitrarily determined by the terminal apparatus # a; alternatively, the terminal apparatus # a does not need to determine whether the quality of the cell # a satisfies a preset condition before performing measurement on the cell # B. For example, the preset condition may be "when the quality of the cell # a is lower than or equal to a certain threshold, the terminal apparatus # a starts measurement of the received measurement object". If the preset condition exists, the terminal device # a ignores the preset condition. That is, when the measurement object received by the terminal apparatus # a includes the cell # B or the frequency point # B where the cell # B is located, the terminal apparatus # a can directly start measurement on the cell # B or the frequency point # B.

Alternatively, the timing at which the terminal apparatus # a measures the cell # B may be defined by the communication system or the communication protocol, or may be configured by a network apparatus (for example, an access apparatus of the cell # a or the cell # B), and the present application is not particularly limited.

Also, the terminal apparatus # a can control measurement for the cell # B based on the obtained measurement result.

For example, the terminal apparatus # a may control measurement for the cell # B based on the measurement result obtained in the period # a.

Here, the start time of the period # a may be arbitrarily determined by the terminal apparatus # a.

For example, the start time of the period # a may be the start time at which the terminal apparatus # a starts measurement on the cell # B.

For another example, the start time of the period # a may be the start time of any one measurement cycle.

Alternatively, the starting time of the period # a may be defined by a communication system or a communication protocol, or may be configured by a network device (for example, an access device of the cell # a or the cell # B), and the present application is not particularly limited.

The duration of the period # a may be arbitrarily determined by the terminal apparatus # a, may be defined by a communication system or a communication protocol, or may be configured by a network apparatus (for example, an access apparatus of the cell # a or the cell # B), and is not particularly limited in the present application.

For example, the period # a may include M measurement cycles.

Wherein M may be an integer greater than or equal to 1.

For example, the value of M may be defined by a communication system or a communication protocol, or may be configured by a network device (for example, an access device of cell # a or cell # B), and the present application is not particularly limited.

It should be noted that, when M is greater than 1, the number of the measurement results # a may be multiple, for example, M, that is, the M measurement periods correspond to M measurement results # a one-to-one, and each measurement result is a measurement result obtained in the corresponding measurement period.

In addition, the M measurement periods may be continuous or discontinuous, and the present application is not particularly limited.

By way of example, and not limitation, the measurement of cell # B by terminal device # a may refer to: measurements are made of signals (e.g., reference signals) from cell # B, specifically, access device transmissions that provide cell # B.

For example, the measurement result may include any one or more parameters of Reference Signal Received Power (RSRP), Signal Noise Ratio (SNR), Received Signal Strength Indication (RSSI), Reference Signal Received Quality (RSRQ), and the like of the cell B.

Specifically, as an example, the terminal apparatus # a controls measurement for the cell # B based on the obtained M measurement results # a, and may include at least one of the following two ways:

in the manner 1, the terminal apparatus # a can determine whether to stop the measurement of the cell # B based on the M measurement results # a.

In the manner 2, the terminal apparatus # a can determine whether to increase the time interval between two adjacent measurements of the cell # B (or, in other words, whether to extend the measurement period) based on the M measurement results # a.

The two different control modes are explained below.

Mode 1

The terminal apparatus # a may determine whether to stop the measurement of the cell # B based on the M measurement results # a (e.g., first measurement values).

Specifically, the terminal apparatus # a may make a preset decision (denoted as decision # a) based on the M measurement results # a, and determine whether to stop the measurement of the cell # B according to the result of the decision # a.

For example, when M is 1, the decision # a may include:

whether the measurement # a is less than or equal to a preset threshold # a1 (e.g., a first threshold).

The threshold # a1 may be arbitrarily determined by the terminal apparatus # a, may be defined by a communication system or a communication protocol, or may be configured by a network apparatus (for example, an access apparatus of the cell # a or the cell # B), and is not particularly limited in the present application.

If the determination is yes, the measurement of cell # B may be stopped.

If the result of the determination is negative, the measurement of the cell # B may be continued, for example, the current measurement state may be maintained.

For another example, when M > 1, the decision # a may include:

decision # a 1: whether the measurement # a1 is less than or equal to a preset threshold # a2 (e.g., a first threshold); and/or the presence of a gas in the gas,

decision # a 2: whether the difference between the two measurements is less than or equal to a preset threshold # a 3.

In particular, the speed of change of the measurement and whether the signal is getting better or worse can be determined from the difference. For example, if the signal is deteriorating, or if the signal is improving but changing slowly, the measurement can be stopped. Therefore, the decision # a2 may be further defined as: whether the difference between the next measurement # a2 and the previous measurement # A3 is less than or equal to a preset threshold # A3 (e.g., a second threshold) in the measurement precedence order.

The judgment # a1 and the judgment # a2 may be performed individually or in combination.

Among them, the measurement # a1, the measurement # a2, and the measurement # A3 may be determined according to at least one of the M measurement # a.

Alternatively, measurement # a2 and measurement # A3 represent only multiple measured results. Measurement # a2 or # A3 may be equal to measurement # a 1.

Wherein the threshold # A2 may or may not be equal to the aforementioned threshold # A1.

For example, the thresholds # a2 and # A3 may be arbitrarily determined by the terminal apparatus # a, may be defined by a communication system or a communication protocol, or may be configured by a network apparatus (for example, an access apparatus of the cell # a or the cell # B), and the present invention is not particularly limited.

The threshold # a2 and the threshold # A3 may be the same or different. As an example, the threshold # a2 may be a quality threshold value and the threshold # A3 may be a quality difference threshold value.

The measurement result # a1 may be any one of the M measurement results # a, for example, the first measurement result or the last measurement result in the measurement order, or the largest measurement result or the smallest measurement result.

Measurement # A1 may also refer to any one or more of the measurements # A as mathematically manipulated. For example, it may refer to an average value of a plurality of measurement results # a.

According to the sequence of measurement, the measurement result # A2 is measured after the measurement result # A3, and the difference between the measurement result # A2 and the measurement result # A3 can be greater than, equal to or less than zero.

The measurement # a2 and the measurement # A3 may also refer to a value obtained by mathematically operating one or more measurements # a, for example, may refer to an average value of a plurality of measurements # a.

As a determination manner, if the determination result of the above determination # a1 is yes and/or the determination result of the determination # a2 is yes, the measurement of the cell # B may be stopped.

Otherwise, the measurement of cell # B may be continued, e.g., the current measurement state may be maintained.

Stopping the measurement of cell # B may be accomplished by any of the following ways, as an example.

In the method a, after the terminal apparatus # a determines that the measurement needs to be stopped (specifically, the measurement for the cell # B), a timer # a may be started, where the timer # a is used to indicate a time period for stopping the measurement for the second cell. For example, during the counting of the timer # a, the measurement of the cell # B is stopped. The timer # a may be started immediately when it is determined that the measurement needs to be stopped, or the timer # a may be started after the measurement is performed once or multiple times after it is determined that the measurement needs to be stopped, or the timer # a may be started after a certain period of time elapses after it is determined that the measurement needs to be stopped, which is not limited in the present application. Further, after the timer # a stops, the measurement of the cell # B may be restarted.

Further, the timer # a may also be configured to measure the cell # B during counting and start measurement of the cell # B after the timer # a stops. For example, measurements for cell # B may be initiated at the same time that timer # a is stopped.

The time length measured by the timer # a may be arbitrarily determined by the terminal apparatus # a, may be defined by a communication system or a communication protocol, or may be configured by a network apparatus (for example, an access apparatus of the cell # a or the cell # B), which is not particularly limited in the present application.

The duration of the timer should be longer than the time interval between two adjacent measurements (or longer than the measurement period).

For example, the duration of the timer # A may be 100ms, 5min, 10min, 20min, etc.

Mode B, after the terminal apparatus # a determines that the measurement needs to be suspended (specifically, measurement for the cell # B), the counter # a may be started, and the counter is incremented (or decremented) by 1 every lapse of one measurement period after the start of the counter # a, and during the counting of the counter, the measurement for the cell # B is stopped, and when the count of the counter # a reaches a prescribed count value (or, zeroed), the measurement for the cell # B is restarted.

The count value of the counter # a may be arbitrarily determined by the terminal apparatus # a, may be defined by a communication system or a communication protocol, or may be configured by a network apparatus (for example, an access apparatus of the cell # a or the cell # B), and the present application is not particularly limited.

For example, the count value may be 2, 4, 8, 16, 30, etc.

Mode 2

The terminal apparatus # a may measure the cell # B using the first time interval, and the terminal apparatus # a determines whether to increase the time interval between two adjacent measurements of the cell # B based on the obtained M measurement results # a (e.g., the first measurement value).

Specifically, the terminal apparatus # a may make a preset decision (denoted as decision # B) based on the M measurement results # a, and determine whether to increase the time interval between two adjacent measurements of the cell # B according to the result of the decision # B.

For example, when M is 1, the decision # B may include:

whether the measurement # a is less than or equal to a preset threshold # B1 (e.g., a first threshold).

The threshold # B1 may be arbitrarily determined by the terminal apparatus # a, may be defined by a communication system or a communication protocol, or may be configured by a network apparatus (for example, an access apparatus of the cell # a or the cell # B), and is not particularly limited in the present application.

If the determination is yes, the measurement time interval may be increased (or the measurement period may be extended).

If the result of the determination is negative, the measurement time interval may not be increased, for example, the current measurement state may be maintained.

For another example, when M > 1, the decision # B may include:

decision # B1: whether the measurement # a4 is less than or equal to a preset threshold # B2 (e.g., a first threshold); alternatively, the first and second electrodes may be,

decision # B2: whether the difference between the two measurements is less than or equal to a preset threshold # B3.

In particular, the speed of change of the measurement and whether the signal is getting better or worse can be determined from the difference, e.g. the signal is getting worse or the signal is getting better but the speed of change is slow, the measurement time interval can be increased. For example, the decision # B2 may be: whether the difference between the next measurement # a5 and the previous measurement # a6 is less than or equal to a preset threshold # B3 (e.g., a second threshold) in the measurement precedence order.

The determination # B1 and the determination # B2 may be determined individually or in combination.

Among them, the measurement # a4, the measurement # a5, and the measurement # a6 may be determined according to at least one of the M measurement # a.

Alternatively, measurement # a5 and measurement # a6 represent only multiple measured results. Measurement # a5 or # a6 may be equal to measurement # a 4.

Wherein, the threshold # B2 may or may not be equal to the aforementioned threshold # B1.

For example, the thresholds # B2 and # B3 may be arbitrarily determined by the terminal apparatus # a, may be defined by a communication system or a communication protocol, or may be configured by a network apparatus (for example, an access apparatus of the cell # a or the cell # B), and the present invention is not particularly limited.

The threshold # B2 and the threshold # B3 may be the same or different. As an example, the threshold # B2 may be a quality threshold #5 and the threshold # B3 may be a quality difference threshold # 3.

Here, the measurement # a4 may be any one of M measurement # a. For example, it may be the first or the last in the measurement order, or it may be the one with the largest or the smallest value.

Measurement # A4 may also refer to any one or more of the measurements # A as mathematically manipulated. For example, it may refer to an average value of a plurality of measurement results # a.

According to the sequence of measurement, the measurement result # A5 is measured after the measurement result # A6, and the difference between the measurement result # A5 and the measurement result # A6 can be greater than, equal to or less than zero.

The measurement # a5 and the measurement # a6 may also refer to a value obtained by mathematically operating one or more measurements # a, for example, may refer to an average value of a plurality of measurements # a.

As a determination, if the determination result of the above determination # B1 is yes or the determination result of the determination # B2 is yes, the measurement time interval may be increased (or the measurement period may be extended).

Otherwise, the measurement time interval may not be increased, e.g. the current measurement state may be maintained unchanged.

As an example, this increase in the measurement time interval may be performed as follows.

After the terminal apparatus # a determines that the measurement time interval needs to be increased (specifically, measurement for the cell # B), the terminal apparatus # a increases the time interval between two adjacent measurements of the cell # B. For example, the current first time interval may be changed to a second time interval that is greater than the first measurement interval, e.g., the first time interval may be 200ms and the second time interval may be 300 ms.

Increasing the time interval between two adjacent measurements may be increasing the current time interval by a certain length of time, so that the time interval between the subsequent measurements becomes longer, or the subsequent measurement period is longer.

Here, the current time interval may be a time interval when the last measurement is performed before the terminal apparatus # a determines that the measurement time interval needs to be increased.

The current time interval may be an initial time interval of the measurement or an increased time interval.

The specific time period may be arbitrarily determined by the terminal apparatus # a, may be defined by a communication system or a communication protocol, or may be configured by a network apparatus (for example, an access apparatus of the cell # a or the cell # B), and is not particularly limited in the present application.

For example, the current time interval between two adjacent measurements of the cell # B is 200ms, the specific duration is 100ms, and after the terminal device needs to increase the measurement interval, the time interval of the subsequent measurement may be increased to 300 ms.

Referring to fig. 3, when the terminal apparatus # a controls the measurement of the cell # B by the manner 2, and after the terminal apparatus # a increases the time interval between the adjacent two measurements of the cell # B (for example, when the time interval is changed to a second measurement interval which is greater than the first time interval), the terminal apparatus # a may continue the measurement of the cell # B.

For example, the terminal apparatus # a may determine whether to resume the time interval based on the measurement result obtained in the period # B (note, measurement result # B). For example, it may be determined whether to resume use of the first time interval.

Wherein the start time of the period # B may be the end time of the period # a, or the start time of the period # B may be after the end time of the period # a.

For example, the start time of the period # B may be the start time of any one measurement cycle after the period # a.

Alternatively, the starting time of the period # B may be defined by a communication system or a communication protocol, or may be configured by a network device (for example, an access device of the cell # a or the cell # B), and the present application is not particularly limited.

The duration of the period # B may be arbitrarily determined by the terminal apparatus # a, may be defined by a communication system or a communication protocol, or may be configured by a network apparatus (for example, an access apparatus of the cell # a or the cell # B), and is not particularly limited in this application.

For example, the period # B may include N measurement cycles.

Wherein N may be an integer greater than or equal to 1.

For example, the value of N may be defined by a communication system or a communication protocol, or may be configured by a network device (for example, an access device of cell # a or cell # B), and the present application is not particularly limited.

It should be noted that, when N is greater than 1, the number of the measurement results # B may be multiple, for example, N, that is, the N measurement periods correspond to the N measurement results # B one by one, and each measurement result is a measurement result obtained in the corresponding measurement period.

Specifically, the terminal apparatus # a determines whether to resume the time interval based on the N measurement results # B (e.g., second measurement values).

For example, the terminal apparatus # a may make a preset determination (denoted as determination # C) based on the N measurement results # B, and determine whether to resume the time interval according to the result of the determination # C.

For example, when N ═ 1, the determination # C may include:

it is determined whether the measurement # B is greater than a preset threshold # C1.

The threshold # C1 may be arbitrarily determined by the terminal apparatus # a, may be defined by a communication system or a communication protocol, or may be configured by a network apparatus (for example, an access apparatus of the cell # a or the cell # B), and is not particularly limited in the present application.

If the determination is yes, the time interval may be restored. For example, the first time interval may be resumed.

If the result of the determination is negative, the time interval may not be resumed, e.g., the current measurement state is maintained.

For another example, when N > 1, the decision # C may include:

decision # C1: whether the measurement # B1 is greater than a preset threshold # C2; and/or the presence of a gas in the gas,

decision # C2: whether the difference between the two measurements is greater than a preset threshold # B3.

Specifically, it is possible to determine the speed of change of the measurement result and whether the signal is getting better or worse based on the difference, and for example, the determination # B2 may be whether the difference between the next measurement result # B2 and the previous measurement result # B3 is greater than a preset threshold # C3 in the measurement order.

The judgment # C1 and the judgment # C2 may be performed individually or in combination.

Wherein, the threshold # C2 may be equal to or not equal to the aforementioned threshold # C1.

For example, the thresholds # C2 and # C3 may be arbitrarily determined by the terminal apparatus # a, may be defined by a communication system or a communication protocol, or may be configured by a network apparatus (for example, an access apparatus of the cell # a or the cell # B), and the present invention is not particularly limited.

The threshold # C1 and the threshold # C2 may be the same or different. As an example, the threshold # C2 may be a quality threshold #5 and the threshold # C3 may be a quality difference threshold # 3.

Wherein the measurement # B1 may be determined according to at least one of the N measurements # B. For example, it may be the first or the last in the measurement order, or it may be the one with the largest or the smallest value.

Measurement # B1 may also refer to a numerical value obtained by mathematically operating on any one or more measurements # B. For example, it may refer to an average value of a plurality of measurement results # B.

According to the sequence of measurement, the measurement result # B2 is measured after the measurement result # B3, and the difference between the measurement result # B2 and the measurement result # B3 can be greater than, equal to or less than zero.

Measurement # B2 and measurement # B3 may also refer to one or more of the measurements # B as mathematically operated on. For example, it may refer to an average value of a plurality of measurement results # B.

As a determination manner, if the determination result of the above determination # C1 is yes and/or the determination result of the determination # C2 is yes, the time interval may be restored.

Otherwise, the time interval may not be restored, e.g. the current measurement state is maintained unchanged.

As an example, the recovery time interval may be performed as follows.

After the terminal apparatus # a determines that the recovery time interval is required (specifically, measurement for the cell # B), the terminal apparatus # a can recover the current time interval. For example, the first time interval is restored to use. Optionally, the first time interval may be an initial time interval (or, alternatively, a default time interval).

After period # a has elapsed, the time interval has been increased to some time interval greater than the initial time interval. For example, the first time interval is increased to the second time interval.

The recovering of the current time interval may be a recovering of the current time interval to a time interval shorter than the current time interval, such as an initial time interval, which is not limited in this application.

Here, the current time interval may be a time interval when the last measurement is performed before the terminal apparatus # a determines that the time interval needs to be recovered.

The foregoing embodiment discusses that the terminal apparatus # a controls the measurement of the cell # B thereafter based on the obtained measurement result of the cell # B. On this basis, the following discusses the effect that the terminal apparatus # a may have on the measurement for the cell # B based on the obtained measurement result for the cell # a.

The terminal apparatus # a can perform measurement on the cell # a.

Also, the terminal apparatus # a may measure the cell # a in the period # C.

The start time of the period # C may be arbitrarily determined by the terminal apparatus # a.

For example, the start time of the period # C may be the start time at which the terminal apparatus # a starts to perform measurement on the cell # B or the cell # a.

For another example, the start time of the period # C may be the start time of any one measurement cycle for the cell # B or the cell # a.

Alternatively, the starting time of the period # C may be defined by a communication system or a communication protocol, or may be configured by a network device (for example, an access device of the cell # a or the cell # B), and the present application is not particularly limited.

The duration of the period # C may be arbitrarily determined by the terminal apparatus # a, may be defined by a communication system or a communication protocol, or may be configured by a network apparatus (for example, an access apparatus of the cell # a or the cell # B), and is not particularly limited in the present application.

For example, the period # C may include S measurement cycles.

Wherein S may be an integer greater than or equal to 1.

For example, the value of S may be defined by a communication system or a communication protocol, or may be configured by a network device (for example, an access device of the cell # a or the cell # B), and the present application is not particularly limited.

It should be noted that when S is greater than 1, the number of the measurement results # C may be multiple, for example, S, that is, the S measurement periods correspond to the S measurement results # C one by one, and each measurement result is a measurement result obtained in the corresponding measurement period.

In addition, the S measurement periods may be continuous or discontinuous, and the present application is not particularly limited.

By way of example, and not limitation, the measurement of cell # a by terminal device # a may refer to: measurements are made on signals (e.g., reference signals) from cell a, specifically the access device providing cell # a.

For example, the measurement result may include any one or more parameters of Reference Signal Receiving Power (RSRP), Signal to Noise Ratio (SNR), Received Signal Strength Indication (RSSI), Reference Signal Receiving Quality (RSRQ), and the like of the cell a.

As a possible implementation, the parameter types of the measurement result of the terminal apparatus # a for the cell # a and the measurement result for the cell # B may be the same.

Referring to fig. 3, the terminal apparatus # a controls measurement for the cell # B based on the obtained M measurement results # a for the cell # B, and may further include the following manners:

mode 3, the terminal apparatus # a may proceed with the determination based on the M measurement results # a and the S measurement results # C to determine whether to stop the measurement of the cell # B or to determine whether to increase the time interval of the measurement of the cell # B. If the determination result is yes, the measurement for the cell # B may be controlled, for example, the time interval for the measurement for the cell # B may be increased, and/or the measurement for the cell # B may be stopped.

Specifically, the terminal apparatus # a may make a determination based on the M measurement results # a, may continue the determination based on the S measurement results # C if the determination result is yes, and may perform the control method for the cell # B measurement in the method 1 and/or the method 2 if the determination result is still yes.

The process in which the terminal apparatus # a makes a determination based on the M measurement results # a can be referred to the contents described in the foregoing manner 1 and manner 2.

For example, the terminal apparatus # a may perform the aforementioned decision # a or decision # B based on the M measurement results # a.

On the premise that the result of the decision # a or the decision # B is yes, the terminal apparatus # a may make a preset decision (denoted as decision # D) based on the S measurement results # C (e.g., the second measurement value or the third measurement value), and control the measurement for the cell # B according to the result of the decision # D.

For example, when S ═ 1, the determination # D may include:

it is determined whether the measurement result # C is greater than a preset threshold # D1 (e.g., a third threshold).

The threshold # D1 may be arbitrarily determined by the terminal apparatus # a, may be defined by a communication system or a communication protocol, or may be configured by a network apparatus (for example, an access apparatus of the cell # a or the cell # B), and is not particularly limited in the present application.

If the determination result is still yes, the measurement for the cell # B may be further controlled according to the measurement value of the cell # B, for example, the time interval of the measurement for the cell # B may be increased, and/or the measurement for the cell # B may be stopped (for a specific control procedure, see the related description in manner 1 or manner 2 above).

If the determination result is no, the state of measurement on cell # B may be maintained. For example, the measurement may continue for cell # B at the current measurement interval.

For another example, when S > 1, the decision # D may include:

decision # D1: whether the measurement # C1 is greater than a preset threshold # D2 (e.g., a third threshold); and/or the presence of a gas in the gas,

decision # D2: whether the difference between the two measurements is less than a preset threshold # C3.

Specifically, it is possible to determine the speed of change of the measurement result and whether the signal is getting better or getting worse based on the difference, and for example, the determination # D2 may be whether the difference between the previous measurement result # C2 and the next measurement result # C3 is smaller than a preset threshold # D3 in the order of measurement.

The judgment # D1 and the judgment # D2 may be performed individually or in combination.

Among them, the measurement # C1, the measurement # C2, and the measurement # C3 may be determined according to at least one of the S measurements # C.

Wherein, the threshold # D2 may or may not be equal to the aforementioned threshold # D1.

For example, the thresholds # D2 and # D3 may be arbitrarily determined by the terminal apparatus # a, may be defined by a communication system or a communication protocol, or may be configured by a network apparatus (for example, an access apparatus of the cell # a or the cell # B), and the present invention is not particularly limited.

The threshold # D2 and the threshold # D3 may be the same or different. As an example, the threshold # D2 may be a cell reselection threshold #5 of terminal apparatus # a, and the threshold # D3 may be a quality difference threshold # 3.

The measurement result # C1 may be any one of the S measurement results # C, for example, the first measurement result or the last measurement result in the measurement order, or the largest measurement result or the smallest measurement result.

The measurement # C1 may also refer to a value obtained by mathematically operating any one or more of the measurements # C, for example, may refer to an average value of a plurality of the measurements # C.

According to the sequence of measurement, the measurement result # C2 is measured before the measurement result # C3, and the difference between the measurement result # C2 and the measurement result # C3 can be greater than, equal to or less than zero.

The measurement # C2 and the measurement # C3 may also refer to a value obtained by mathematically operating one or more measurements # C, for example, may refer to an average value of a plurality of measurements # C.

As a determination manner, if the determination result of the determination # D1 is still yes and/or the determination result of the determination # D2 is still yes, the measurement on the cell # B may be controlled, for example, the time interval of the measurement on the cell # B may be increased and/or the measurement on the cell # B may be stopped (for a specific control procedure, see the related description in manner 1 or manner 2).

Otherwise, the state of the measurement of cell # B may be maintained.

Further, the terminal apparatus # a controls measurement for the cell # B based on the obtained M measurement results # a for the cell # B, and may further include the mode 4.

Mode 4 is a variation of mode 3, and mode 4 may make the determination of decision # D at a time after performing mode 1 and/or mode 2 of

modes

1, 2, and/or 3, for example, the time may have stopped measuring cell # B and/or the time may have increased the measurement time interval for cell # B.

If the result of the above decision # D is YES, the current measurement state may be maintained. For example, the timer is still kept running and the measurement of cell # B is suspended during the timer running time and/or the measurement interval of cell # B is still increased.

If the result of the above decision # D is negative, i.e. when the measurement result # C is less than or equal to the preset threshold # D1, the timer may be stopped, the measurement of the cell # B resumed (or, alternatively, started) after the timer has stopped, and/or the time interval resumed to a time interval shorter than the current time interval, e.g. resumed from the second time interval to the first time interval.

Likewise, if the above-described determination result of the determination # D1 is yes, or the determination result of the determination # D2 is yes, the current measurement state may be maintained unchanged, for example, the measurement of the cell # B is still kept suspended, and/or the current measurement time interval of the cell # B is not changed.

If the result of the above decision # D1 is negative, i.e. when the measurement result # C is less than or equal to the preset threshold # D2, the measurement of cell # B may be resumed, and/or the time interval, e.g. the first time interval, is resumed.

Or the result of the decision # D2 is determined to be no, that is, at this time, according to the measurement sequence, the difference between the previous measurement result # C2 and the next measurement result # C3 is greater than or equal to the preset threshold # D3, the measurement of the cell # B can be resumed, and/or the time interval can be resumed.

For example, resuming the measurement of cell # B may be performed as follows.

After the period # a has elapsed, if the terminal apparatus # a currently stops the measurement of the cell # B, or is currently in the running period of the timer # a, or is in the counting period of the counter # a, after the terminal apparatus # a determines that the measurement needs to be resumed (specifically, the measurement for the cell # B), the timer # a is stopped, or the counter # a may start the measurement for the cell # B. Alternatively, the timer # a or the counter # a may be reset.

For example, restoring the time interval may be performed as follows.

After the period # a elapses, if the terminal apparatus # a increases the time interval of measurement (for example, the measurement interval at this time is the second measurement interval), the use of the first time interval may be resumed after the terminal apparatus # a determines that the time interval needs to be resumed.

After period # a has elapsed, the time interval has been increased to some time interval greater than the initial time interval.

The recovering of the current time interval may be recovering the measured time interval to a time interval shorter than the current time interval, such as an initial time interval, which is not limited in this application.
