Technical field

This application relates to the field of communication technology, and in particular to a relaxation measurement method and communication device.

Background technique

Due to the mobility of the terminal, the terminal may move from the coverage of one cell to the coverage of another cell. In order to ensure the service continuity and communication quality of the terminal, the terminal will perform cell reselection or cell handover. Both cell reselection and cell handover require the terminal to perform cell measurement, that is, the terminal performs radio resource management (RRM) measurement. Among them, when the terminal device is in a radio resource control (radio resource control, RRC) idle state (referred to as RRC_idle state for short) and in an RRC deactivated state (referred to as RRC_inactive state for short), the terminal device performs RRM measurement and cell reselection processes.

The terminal in the RRC_idle state and the RRC_inactive state periodically performs RRM measurement. However, in some scenarios, for example, when the terminal is in a stationary state or the moving speed of the terminal is low, it is not necessary to perform RRM measurements frequently. Therefore, in order to reduce the power consumption of the terminal, the concept of RRM measurement relaxation is currently proposed, that is, the terminal can perform RRM relaxation measurement when certain measurement scenarios are met. For example, the terminal can reduce the number of RRM measurements (for example, Increase the measurement interval of RRM measurement). And different measurement scenarios, the implementation of RRM relaxation measurement strategies are also different. For example, if the terminal is not on the edge of a cell, the terminal may not perform RRM measurement on the neighboring cell; for another example, if the terminal moves at a low speed, the terminal may perform RRM measurement at a longer measurement interval.

However, there is no further solution for how the terminal performs RRM relaxation measurement after the terminal switches between different measurement scenarios.

Summary of the invention

This application provides a relaxation measurement method and communication device, which clarifies the relaxation measurement strategy that the terminal should adopt after switching between different measurement scenarios, so as to take into account the terminal's energy consumption requirements and communication performance requirements.

In the first aspect, the embodiments of the present application provide a relaxation measurement method, which can be executed by a first communication device. The first communication device may be a terminal or a communication device capable of supporting the terminal to implement the functions required by the method, such as a chip. system. The following description will be made by taking an example in which the first communication device is a terminal. The method includes:

The terminal switches from the first relaxation measurement scenario to the second relaxation measurement scenario, and then the terminal adopts the target relaxation measurement strategy to perform relaxation measurement, where one relaxation measurement scenario corresponds to a relaxation measurement strategy, and the target relaxation measurement strategy includes the second relaxation measurement strategy. The relaxation measurement strategy corresponding to the measurement scenario. This solution can clarify the relaxation measurement strategy adopted by the terminal after the relaxation measurement is performed when the terminal switches to the relaxation measurement scenario.

In the first possible implementation manner, the first relaxation measurement scenario corresponds to the first relaxation measurement strategy, the second relaxation measurement scenario corresponds to the second relaxation measurement strategy, and the target relaxation measurement strategy includes switching from the first relaxation measurement strategy to the second relaxation measurement strategy. Measurement strategy. In this solution, the terminal directly switches from the first relaxation measurement strategy to the second relaxation measurement strategy, that is, directly switches to the relaxation measurement strategy corresponding to the second relaxation measurement scenario, which is relatively simple.

Further, the energy consumption corresponding to the first relaxation measurement strategy is higher than the energy consumption corresponding to the second relaxation measurement strategy, the terminal switches from the first relaxation measurement scenario to the second relaxation measurement scenario, and the terminal directly switches from the first relaxation measurement strategy To the second relaxation measurement strategy. That is, after the terminal switches from a high energy consumption measurement scenario to a low energy consumption measurement scenario, the terminal directly switches from a high energy consumption measurement strategy to a low energy consumption measurement strategy, so as to save the energy consumption of the terminal to the greatest extent.

Further, the energy consumption corresponding to the first relaxation measurement strategy is lower than the energy consumption corresponding to the second relaxation measurement strategy, the terminal switches from the first relaxation measurement scenario to the second relaxation measurement scenario, and the terminal directly switches from the first relaxation measurement strategy To the second relaxation measurement strategy. That is, after the terminal switches from a low energy consumption measurement scenario to a high energy consumption measurement scenario, the terminal directly switches from a low energy consumption measurement strategy to a high energy consumption measurement strategy, so as to maximize the communication performance of the terminal.

In a second possible implementation manner, the first relaxation measurement scenario corresponds to the first relaxation measurement strategy, the second relaxation measurement scenario corresponds to the second relaxation measurement strategy, and the target relaxation measurement strategy includes performing the third relaxation within the first preset time period. The measurement strategy, after the first preset period of time, executes the second relaxation measurement strategy. In this solution, after the terminal switches the measurement scene, it executes a relaxation measurement scenario first, and then executes the second relaxation measurement strategy, that is, the terminal transitions to the second relaxation measurement strategy, so as to save the energy consumption of the terminal as much as possible while ensuring the terminal’s power consumption. Communication performance.

Further, the energy consumption corresponding to the first relaxation measurement strategy is lower than the energy consumption corresponding to the second relaxation measurement strategy, the terminal switches from the first relaxation measurement scenario to the second relaxation measurement scenario, first executes a relaxation measurement scenario, and then Perform the second relaxation measurement strategy. That is, after the terminal switches from a low-power measurement scenario to a high-power measurement scenario, the terminal transitions from a low-power measurement strategy to a high-power measurement strategy, so as to ensure the communication performance of the terminal while saving the power consumption of the terminal as much as possible.

Further, the energy consumption corresponding to the first relaxation measurement strategy is higher than the energy consumption corresponding to the second relaxation measurement strategy, the terminal switches from the first relaxation measurement scenario to the second relaxation measurement scenario, first executes a relaxation measurement scenario, and then Perform the second relaxation measurement strategy. That is, after the terminal switches from a high energy consumption measurement scene to a low energy consumption measurement scene, the terminal transitions from a high energy consumption measurement strategy to a low energy consumption measurement strategy, so as to save the energy consumption of the terminal while ensuring the communication performance of the terminal as much as possible.

In a possible implementation manner, the third relaxation measurement strategy may include any one of the following strategies:

Exemplarily, the third relaxation measurement strategy may include the first relaxation measurement strategy. That is, the terminal first executes the first relaxation measurement strategy adopted before, so as to avoid frequent switching between different measurement strategies.

In another example, the third relaxation measurement strategy may include performing relaxation measurement according to at least one preset measurement parameter, where the at least one measurement parameter includes one or more of the following parameters: measurement interval, neighboring area to be measured The number of frequency points to be tested in the neighboring area to be tested. The third relaxation measurement strategy can perform relaxation measurement according to preset measurement parameters. The value of the measurement parameter can be preset, which is different from the first relaxation measurement strategy or the second relaxation measurement strategy. Energy-saving requirements and terminal communication performance requirements.

Wherein, performing relaxation measurement according to at least one preset measurement parameter may include:

Solution 1: Perform relaxation measurement according to the first value of the first measurement parameter, where the first measurement parameter is any one of the at least one measurement parameter. That is, the relaxed measurement is performed according to the fixed value of the measurement parameter, which reduces the complexity.

Solution 2: Perform relaxation measurement according to the second value of the first measurement parameter, wherein the second value is obtained by adjusting the first value according to a preset rule, and the first value is the preset The initial value of the first measurement parameter.

Exemplarily, the preset rule includes sequentially decreasing the first value according to the adjustment factor; or, the preset rule includes sequentially increasing the first value according to the adjustment factor. That is, within the preset time period, the value of the measurement parameter is variable, and the measurement method is performed according to the variable value, which is more helpful to balance the energy-saving requirements of the terminal and the communication performance requirements of the terminal.

In a possible implementation manner, the energy consumption corresponding to the first relaxation measurement strategy is lower than the energy consumption corresponding to the second relaxation measurement strategy. For example, the first relaxation measurement scenario indicates that the terminal is not at the edge of the cell and the moving speed of the terminal is lower than a preset threshold, and the second relaxation measurement scenario indicates that the terminal is not at the edge of the cell or the moving speed of the terminal is lower than the preset threshold.

In this case, the first relaxation measurement strategy includes performing relaxation measurement according to the third value of the first measurement parameter, and the second relaxation measurement strategy includes performing relaxation measurement according to the fourth value of the first measurement parameter. The value is greater than the second value, the first value is greater than the fourth value, and the second value is greater than or equal to the fourth value. In this solution, after the terminal switches from the low-energy measurement scenario to the high-energy measurement scenario, the terminal can sequentially reduce the value of the measurement parameter within a period of time, obtain the second value, and perform the relaxation measurement according to the second value. The second value is greater than or equal to the fourth value, which can gradually improve the communication performance of the terminal.

In a possible implementation manner, the energy consumption corresponding to the first relaxation measurement strategy is higher than the energy consumption corresponding to the second relaxation measurement strategy. For example, the first relaxation measurement scenario indicates that the terminal is not at the edge of the cell or the moving speed of the terminal is lower than a preset threshold, and the second relaxation measurement scenario indicates that the terminal is not at the edge of the cell and the moving speed of the terminal is lower than the preset threshold.

In this case, the first relaxation measurement strategy includes performing relaxation measurement according to the third value of the first measurement parameter, and the second relaxation measurement strategy includes performing relaxation measurement according to the fourth value of the first measurement parameter. The value is greater than the second value, and the first value is greater than the third value, and the second value is greater than or equal to the third value; or, the first value is less than the second value, and the first value Is less than the third value, and the second value is less than or equal to the third value. In this solution, after the terminal switches from a high energy consumption measurement scene to a low energy consumption measurement scene, the terminal can sequentially increase the value of the measurement parameter within a period of time, obtain the second value, and perform the relaxation measurement according to the second value, and because The second value is greater than or equal to the third value, and the communication performance of the terminal can be gradually reduced first, and then the energy-saving effect of the terminal can be improved. Or, after the terminal switches from a high-energy measurement scenario to a low-energy measurement scenario, the terminal can sequentially reduce the value of the measurement parameter within a period of time, obtain the second value, and perform the relaxation measurement according to the second value. If the second value is less than or equal to the third value, the energy saving effect of the terminal can be gradually improved, and then the communication performance of the terminal can be reduced.

In this solution, the network device directly instructs the terminal to perform the relaxation measurement according to the measurement parameters, which is simple and direct.

Direct indication mode 2: The indication information is used to indicate multiple relaxation measurement strategies, and the target relaxation measurement strategy is one or more of these multiple relaxation measurement strategies. In this solution, the network device can directly instruct multiple predefined relaxation measurement strategies, which can reduce signaling overhead.

Further, the instruction information is also used to instruct the terminal to execute the target relaxation measurement strategy when switching from the first relaxation measurement scene to the second relaxation measurement scene. In this solution, there is no restriction on the time for the network device to send the instruction information. For example, the network device may send the instruction information before the terminal switches from the first relaxation measurement scenario to the second relaxation measurement scenario.

In an indirect indication mode, the indication information includes a switching criterion by which the terminal switches the relaxation measurement strategy, the switching criterion corresponds to the target relaxation measurement strategy, wherein the switching criterion includes a first criterion or a second criterion, and the first criterion is the first criterion or the second criterion. The criterion indicates that priority is given to saving energy consumption of the terminal, and the second criterion indicates that priority is given to ensuring communication quality. This scheme indirectly instructs the target to relax the measurement strategy through the switching criterion.

Exemplarily, the indication information includes m-bit information, and m is greater than or equal to 1; or, the indication information includes the priority of the terminal service. That is, the switching criterion is indicated by m-bit information or the switching criterion is indicated by the priority of the terminal service, which is more flexible.

In a possible implementation manner, the terminal can determine the target relaxation measurement strategy according to the handover criterion, so as to better meet its own actual needs. For example, if the energy saving requirement is given priority, then the relaxation measurement strategy corresponding to the first criterion can be selected, or the communication quality is guaranteed first, then the relaxation measurement strategy corresponding to the second criterion can be selected.

In the second aspect, the embodiments of the present application provide a relaxation measurement method, which can be executed by a second communication device, and the second communication device may be a network device or a communication device capable of supporting the network device to implement the functions required by the method, For example, chip system.

The UE can establish an RRC connection in RRC_idle, switch to the RRC_connected state, and return to the RRC_idle state by releasing the RRC connection. When the UE in the RRC_connected state is in the low demand state, the release of the RRC connection can be delayed to switch to the RRC_inactive state, and the RRC connection can be released to return to the RRC_idle state. According to the difference in the RRC state between the terminal and the network device, the terminal may be in the RRC_idle state, the RRC_inactive state, or the RRC_connected state.

Figure 3 shows a schematic diagram of the terminal moving in cell 1, cell 2, and cell 3. Due to the mobility of the terminal, the terminal may move from the coverage area of one cell to the coverage area of another cell. In order to ensure the service continuity and communication quality of the terminal, the terminal is required to perform cell reselection (reselection) or cell handover (handover). The terminal obtains the continuous service of the wireless network by reselecting and switching between cells with different coverage areas. Both cell reselection and cell handover require the terminal to perform RRM measurement. The terminal uses RRM measurement to determine whether it is within the coverage of a certain cell, and receives reference signals sent from multiple network devices, and completes cell reselection based on the power of the reference signal Or cell handover.

The cell reselection is mainly implemented by the terminal itself, and the terminal completes the cell reselection after meeting certain trigger conditions and access criteria. The cell handover requires the network equipment to configure RRM measurement parameters for the terminal and configure the terminal according to the feedback of the terminal. When the RRM measurement result of the terminal meets certain conditions, the report of the measurement event will be triggered. After receiving the report from the terminal, the network device can send a handover command to the terminal, instructing the terminal to switch from one cell to another.

The purpose of RRM measurement is to realize the management and allocation of resources. The types of RRM measurement include intra-frequency measurement and inter-frequency/different system measurement. Co-frequency measurement includes measuring other frequency points in the same frequency band of the current serving cell and adjacent cell frequency points that are the same as the center frequency of the frequency band supported by the serving cell; inter-frequency measurement means that the center frequency of the frequency band supported by the serving cell is different from the center frequency of the frequency band supported by the serving cell. Adjacent cell frequency; different system measurement is to measure the adjacent cell frequency that is not in the same system as the serving cell. When the terminal is in the RRC_idle state or the RRC_inactive state, there is no RRC connection between the terminal and the network device. When the signal quality of the cell where the terminal resides (also referred to as the serving cell in this article) is lower than a certain threshold, the terminal according to the same frequency, different frequency and/or different system neighboring cell information configured by the network device in the system message, Measure the signal quality of the serving cell and the neighboring cell of the cell adjacent to the serving cell (also referred to as the neighboring cell in this article), and determine whether the signal quality of the neighboring cell meets the cell reselection condition. If the signal quality of the neighboring cell meets the cell reselection condition, the terminal stays in the neighboring cell. When the terminal is in the RRC_connected state, there is an RRC connection between the terminal and the network device, and the network device configures the terminal to perform intra-frequency, inter-frequency, and/or different system neighbor cell measurements through RRC signaling. The terminal reports the signal quality measurement results of the serving cell and neighboring cells to the network device through RRC signaling, and the network device switches the terminal to a cell with better signal quality according to the measurement result when the terminal is in. Therefore, whether it is the cell reselection in the RRC_idle state and the RRC_inactive state, or the cell handover in the RRC_connected state, it is based on the terminal's signal quality measurement results of the serving cell and neighboring cells.

For inter-frequency and/or inter-system adjacent cell measurement in the connected state, depending on the terminal's capabilities, the terminal can use a measurement method that requires gap measurement, or a measurement method that does not require gap measurement for inter-frequency and/or inter-frequency measurement. Measure in the neighborhood of the system. If the terminal has multiple sets of radio frequency channels that can support receiving signals on different frequencies or neighboring cells of different systems at the same time when transmitting and receiving signals on the serving cell, the terminal supports measurement methods that do not require gap measurement to measure signals of different frequencies or neighboring cells of different systems. ; Otherwise, the terminal adopts the measurement method that requires gap measurement to measure signals of different frequencies or neighboring cells of different systems. The terminal stops the signal transmission and reception on the serving cell in the gap, adjusts the radio frequency path to the different frequency or the different system frequency point, and receives the signals of the different frequency or the neighboring cell of the different system. The network device configures the gap semi-statically through RRC signaling.

Please refer to Figure 4, which is a configuration diagram of gap, which is mainly composed of three parameters. These three parameters are measurement gap repetition period (MGRP), which are used to configure the gap period; measure the length of the time slot. The measurement gap length (MGL) is used to configure the length of the gap; the measurement offset (gapOffset) is used to configure the starting position of the gap. According to these three parameters, it can be determined that the gap starts at the system frame number (SFN) and subframe (subframe) that meet the following conditions:

SFN mod T=FLOOR(gapOffset/10);

subframe=gapOffset mod 10;

T=MGRP/10;

The above SFN and subframe are the SFN and subframe of the primary cell (primary cell, PCell). The maximum MGL is 6ms.

For inter-frequency and/or inter-system neighbor cell measurement in the RRC_idle state and RRC_inactive state, since the terminal does not need to send and receive data on the serving cell of the terminal, there is no need to configure a measurement window.

The measurement of the NR neighbor cell can be based on the synchronization signal block (Synchronization Signal Block, SSB), but due to the particularity of the SSB signal design, if the measurement method that needs to measure the gap is used to perform the connection state inter-frequency or different system neighbor cell measurement), the network The device needs to be configured with an accurate gap location to include the SSB of the neighboring cell.

Accurate gap position, the time domain position of the measurement gap needs to refer to the PCell timing, and the time domain position of the neighboring cell SSB is sent at the neighboring cell timing. In order to configure the correct gap position, the network device needs to know the PCell and the NR neighboring cell Therefore, it is determined that the SFN and subframe number of the SSB of the adjacent cell of the NR correspond to the SFN and subframe number of the PCell. The timing deviation between PCell and NR neighboring cells can be obtained by measuring the system frame number of the terminal and the frame timing difference (SFN and frame timing difference, SFTD). SFTD measurement results include SFN deviation and frame boundary timing deviation.

The current protocol supports (EUTRA-NR Dual Connectivity, EUTRA-NR dual connectivity), also known as SFTD measurement between LTE PCell and NR PSCell under EN-DC, and supports (NR-EUTRA Dual Connectivity, NR-EUTRA dual connectivity) ), also known as SFTD measurement between NR PCell and LTE PSCell under NE-DC, and also supports (NR Dual Connectivity, NR dual connectivity), also known as SFTD measurement between NR PCell and NR PSCell under NR-DC , And supports SFTD measurement between LTE PCell and NR neighbor cells under non-DC (Dual Connectivity).

During SFTD measurement, the terminal needs to receive a signal from another cell under test other than the PCell to obtain the timing information of the cell. In DC, since the terminal can support simultaneous work on PCell and PSCell and know the timing information of PCell and PSCell at any time, there will be no difficulty in SFTD measurement. For SFTD measurement between LTE PCell and NR neighboring cell under non-DC, if the radio frequency path of the terminal does not support receiving and sending signals on PCell while receiving signals on NR neighboring cell, SFTD measurement will be difficult. To this end, the current protocol supports the following two methods: SFTD measurement that requires gap and SFTD measurement in the inactive period of connected discontinuous reception (connected discontinuous reception, CDRX).

Generally speaking, in the measurement gap, the terminal first detects the synchronization signals of other cells, obtains synchronization with other cells based on the synchronization signals of other cells, and then performs related measurements on the reference signals sent by other cells, thereby completing other Measurement of the cell. However, interrupting the receiving and sending of data in the original service area in the measurement gap will have a greater impact on throughput. Some terminals can support CA combinations of many different frequency bands, have multiple receiving channels, and have the ability to directly measure different frequencies/systems without the need to configure gaps. In this way, the data transmission in the original service area is not interrupted, and the service in the original service area of the terminal is not affected. However, if the supported frequency bands and CA combinations are many, there are also many different frequency/different system frequency bands that need to be measured. Based on cost considerations, the terminal usually only supports a limited number of frequency band combinations, and cannot support all frequency band combinations without measuring gap measurement. Different frequency/different system.

For example, in the LTE system, the information element "interFreqNeedForGaps"/"interRAT-NeedForGaps" can be used to report in the capability message which measurement frequency band combinations need to measure gaps, and which measurement frequency band combinations do not need to measure gaps. Among them, the band of the service area is indicated by the cell "bandListEUTRA" that supports single band or the cell "bandCombinationListEUTRA" that supports CA; the target measurement inter-frequency band is indicated by the cell "interFreqBandList", and the target measurement inter-system band It is indicated by the cell "interRAT-BandList". 1 bit is used to indicate the band/CA combination of the service area and whether to measure the gap between different frequency bands or different frequency bands. For example, the value of 1 bit is 1 (True) means that gap measurement is required, and the value of 1 bit is 0 (False). ) Means that no gap measurement is required.

Exemplarily, as shown in Table 1, it is an indication of the measurement capability reported by the terminal. The network device may determine whether to configure the gap during measurement according to Table 1.

Table 1-Schematic of measurement capability information

The network device can determine whether to configure the measurement gap for the terminal according to the measurement capability reported by the terminal, so that the terminal performs RRM measurement according to the configuration of the network device. Since the terminal in the RRC_idle state and the RRC_inactive state periodically performs RRM measurement, it can be considered as the main source of power consumption of the terminal. However, in some measurement scenarios, such as when the terminal is in a stationary state or the moving speed of the terminal is low, it is not necessary to perform RRM measurements frequently. Therefore, in order to reduce the power consumption of the terminal, the concept of RRM relaxation measurement is currently proposed. When the terminal performs RRM relaxation measurement, the terminal can reduce the number of RRM measurements (for example, increase the period of RRM measurement), and for example, the terminal can reduce the measurement objects (for example, the terminal reduces the number of target frequency points to be measured, or the terminal reduces the neighbors to be measured). The number of districts).

In some embodiments, it is proposed that the terminal can perform RRM relaxation measurement when certain measurement scenarios are satisfied. For example, if the terminal is not on the edge of a cell, the terminal may not perform RRM measurement on the neighboring cell; for another example, if the terminal moves at a low speed, the terminal may perform RRM measurement at a longer measurement interval. Different measurement scenarios have different strategies for implementing RRM relaxation measurement. However, due to the mobility of the terminal, the terminal may switch from one measurement scenario to another. For example, the terminal may move from the center of the cell to the edge of the cell, or the moving speed of the terminal becomes faster. This involves the terminal needs to switch the RRM relaxation measurement strategy, but there is no further solution for how the terminal performs the RRM relaxation measurement after the terminal switches in different measurement scenarios.

It should be noted that in the radio link monitoring (RLM) relaxation measurement, the terminal switching monitoring scenario is also involved, and there is also no further solution for how the terminal performs the RLM relaxation measurement after the switching monitoring scenario exists.

In view of this, the embodiments of the present application provide a relaxation measurement method. The solution is aimed at clarifying the relaxation measurement strategy (hereinafter, also referred to as the relaxation measurement strategy) to be adopted by the terminal after the measurement scene is switched, so as to take into account the terminal's performance. Power consumption requirements and communication performance requirements.

The technical solutions provided by the embodiments of the present application can be used in wireless communication systems, such as 4.5G systems or 5G systems, and further evolution systems based on LTE or NR, as well as future wireless communication systems or other similar communication systems. In addition, the technical solutions provided in the embodiments of the present application can be used for RRM measurement, and can also be used for RLM. It should be understood that when the technical solution is used for RRM measurement, the relaxation measurement method provided in the embodiment of this application can also be referred to as the RRM relaxation measurement method; when the technical solution is used for RLM measurement, then the relaxation measurement method provided in the embodiment of the application is It can also be called RLM relaxation measurement method. In the case of no conflict, the RRM in the embodiments of the present application can be replaced with RLM. Hereinafter, the application of the technical solution to RRM measurement is taken as an example, and the technical solution provided by the embodiments of the present application will be described below with reference to the accompanying drawings.

The embodiment of the present application provides an RRM measurement method. In the following introduction, the method is applied to the network architecture shown in FIG. 1 as an example. In addition, the method can be executed by two communication devices, for example, the first communication device and the second communication device. Wherein, the first communication device may be a network device or a communication device (such as a chip system) capable of supporting the network device to realize the functions required by the method, and the first communication device may be a terminal or a communication device capable of supporting the terminal to realize the functions required by the method. Communication device (such as chip system). The same is true for the second communication device. The second communication device may be a network device or a communication device (such as a chip system) capable of supporting the network device to implement the functions required by the method, or the second communication device may be a terminal or capable of supporting terminal implementation A communication device (such as a chip system) with the functions required by the method. And there are no restrictions on the implementation of the first communication device and the second communication device. For example, the first communication device and the second communication device are both terminals, or the first communication device is a terminal, and the second communication device is capable of supporting terminal implementation. The function of the communication device required by the method, and so on. Among them, the network device is, for example, a base station.

Please refer to FIG. 5, which is a flowchart of the RRM measurement method provided by this embodiment of the application. The communication device is a network device as an example. It should be noted that the embodiments of the present application only take execution through network equipment and terminals as examples, and are not limited to these two communication devices.

S501: The terminal switches from the first RRM relaxation measurement scenario to the second RRM relaxation measurement scenario.

S502. The terminal executes a target RRM relaxation measurement strategy, where the target RRM relaxation measurement strategy includes an RRM relaxation measurement strategy corresponding to the second RRM relaxation measurement scenario.

RRM relaxation measurement can be understood as when the terminal performs RRM relaxation measurement, the terminal can reduce the measurement objects (for example, reduce the number of measurement target frequency points, reduce the number of neighboring cells to be measured); or, the terminal can reduce the number of RRM measurements (for example, Extend the measurement interval); or, the terminal reduces the measurement objects and reduces the number of RRM measurements, so as to save the power consumption of the terminal as much as possible.

The RRM relaxation measurement scenario is a scenario suitable for the terminal to perform RRM relaxation measurement. In other words, when the terminal satisfies a certain measurement scenario among these measurement scenarios, the terminal can perform RRM relaxation measurement. Several possible RRM relaxation measurement scenarios are listed below.

Measurement scenario 1: Within a set time period, the signal quality of the serving cell of the terminal does not exceed the set threshold 1, that is, the terminal is stationary or moving at a low speed. In this scenario, the signal quality of the serving cell and the neighboring cell are relatively stable and will remain within a certain range for a long time. Therefore, the terminal can perform RRM relaxation measurement on the serving cell or the neighboring cell.

Measurement scenario 2: The signal quality of the serving cell is higher than the set threshold 2, that is, the terminal device is not at the edge of the cell. In this scenario, the signal quality of the serving cell is high, and it can provide a stable and better service to the terminal. Therefore, the terminal does not need to be reselected to the neighboring cell, and the RRM relaxation measurement can be performed on the neighboring cell.

Measurement scenario 3: The signal quality of the serving cell is higher than the set threshold 2, and the change of the signal quality of the serving cell does not exceed the set threshold 1, that is, the terminal is not at the edge of the cell and the terminal is stationary or moving at a low speed. In this scenario, the signal quality of the serving cell is high, which can provide stable and better services to the terminal, and the signal quality of the serving cell and neighboring cells are relatively stable, and the signal quality will be kept within a certain range for a long time. The cell performs RRM relaxation measurement, and does not perform RRM measurement on neighboring cells.

Although the RRM relaxation measurement method in scenario 1 and scenario 2 can guarantee the cell coverage of the terminal. However, due to the mobility of the terminal, when the terminal may switch from one measurement scene to another, if the measurement method is relaxed according to the RRM corresponding to the measurement scene after the handover, there may be a certain risk of cell handover. For example, when the terminal switches from scenario one to scenario two, that is, the terminal moves at a low speed and is far away from the edge of the cell (that is, not at the edge of the cell), if the terminal performs RRM relaxation measurement on the neighboring cell according to the method of scenario two RRM relaxation measurement, this is It will cause the terminal equipment to be unable to reselect to the neighboring cell for a long time, which will eventually affect the communication performance of the terminal.

In view of this, the embodiment of the present application can clarify the RRM relaxation measurement strategy that the terminal needs to adopt from one RRM relaxation measurement scenario to another RRM relaxation measurement scenario, and the terminal performs RRM relaxation measurement according to the RRM relaxation measurement strategy, which can take into account the energy consumption of the terminal. Requirements and communication performance requirements.

There are a variety of RRM relaxation measurement scenarios, such as the above three measurement scenarios. There are also a variety of RRM relaxation measurement strategies, such as performing RRM relaxation measurement at the first measurement interval, or for example not performing RRM measurement on neighboring cells. Different RRM relaxation measurement scenarios correspond to different RRM relaxation measurement strategies. Exemplarily, as shown in Table 2 below, one RRM relaxation measurement scenario corresponds to an RRM relaxation measurement strategy.

Table 2

In Table 2, Strategy 1 and Strategy 2 may be the same, for example, the first measurement interval and the second measurement interval are the same. Or in Table 2, Strategy 1 and Strategy 2 may also be different, for example, the first measurement interval and the second measurement interval are different; or, the first measurement interval and the second measurement interval are the same, but the number of neighboring cells measured by Strategy 1 is the same as The number of neighbors measured by strategy 2 is different; or, the first measurement interval and the second measurement interval are the same, the number of neighbors measured by strategy 1 is the same as the number of neighbors measured by strategy 2, but strategy 1 corresponds to the measured neighbors The number of frequency points is different from the number of frequency points in the neighboring cell corresponding to strategy 2. Moreover, it should be noted that Table 2 only illustrates strategy 1 to strategy 3 with measurement intervals. In some embodiments, strategy 1 to strategy 3 may respectively be strategies for measuring multiple neighboring cells to perform RRM relaxation measurement. For example, strategy 1 is a strategy for measuring L neighboring cells to perform RRM relaxation measurement; strategy 2 is a strategy for measuring P neighboring cells performing RRM relaxation measurement; strategy 1 is a strategy for measuring Q neighboring cells performing RRM relaxation measurement, where L , P, and Q are all positive integers, and L, P, and Q may be different. In other embodiments, strategy 1 to strategy 3 may be strategies for measuring multiple frequency points of each neighboring cell to perform RRM relaxation measurement. For example, strategy 1 is to measure L frequency points of a neighboring cell to perform RRM relaxation measurement strategy; strategy 2 is to measure P frequency points of a neighboring cell to perform RRM relaxation measurement strategy; strategy 1 is to measure a neighboring cell The Q frequency points of the implementation of the RRM relaxation measurement strategy, where L, P, and Q are all positive integers, and L, P, and Q may be different. It should be understood that, in this article, the implementation of RRM relaxation measurement takes the neighboring cell measurement as an example, but it is not limited to performing RRM relaxation measurement on the serving cell, or performing RRM relaxation measurement on the serving cell and neighboring cells.

It should be understood that in Table 2, in the third measurement scenario, the terminal uses strategy 3 to perform RRM measurement with the lowest energy consumption. That is, the measurement scene 3 is a low energy consumption measurement scene compared to the measurement scene 1 or the measurement scene 2. That is, the energy consumption of the terminal using strategy 3 to perform RRM measurement is lower than the energy consumption of the terminal using strategy 1 or strategy 2 to perform RRM measurement. Compared with the second measurement scenario, the measurement scenario 1 may be a low-power measurement scenario or a high-power measurement scenario. That is, the energy consumed by the terminal using strategy 1 to perform RRM measurement may be greater than or equal to the energy consumed by the terminal using strategy 2 to perform RRM measurement, or it may be less than the energy consumed by the terminal using strategy 2 to perform RRM measurement.

It should be understood that the terminal adopts strategy 1 in the measurement scenario 1 (or the terminal adopts strategy 2 in the measurement scenario 2) to perform RRM measurement, compared to the terminal adopts the strategy 3 in the measurement scenario 3, which can better ensure the communication performance of the terminal. In other words, the communication performance of measurement scenario 3 is the lowest, and the communication performance of measurement scenario 1 may be higher than that of measurement scenario 2, or may be lower than that of measurement scenario 2.

In addition, it should be noted that Table 2 only takes as an example that there are three RRM relaxation measurement scenarios, and each RRM relaxation measurement scenario corresponds to one RRM relaxation measurement strategy. However, the embodiment of the present application does not limit the number of RRM relaxation measurement scenarios and the number of RRM relaxation measurement strategies. And in the following description, take the one-to-one correspondence between the RRM relaxation measurement scenario and the RRM relaxation measurement strategy as an example, that is, the RRM relaxation measurement scenario M corresponds to the RRM relaxation measurement strategy M, and the RRM relaxation measurement scenario N corresponds to the RRM relaxation measurement strategy N, M, and N. different.

It should be understood that when the terminal switches from one RRM relaxation measurement scenario to another RRM relaxation measurement scenario, the corresponding RRM relaxation measurement strategy also needs to be adjusted. That is, after the terminal switches from the RRM relaxation measurement scenario M to the RRM relaxation measurement scenario N, the terminal can execute the target RRM relaxation measurement strategy.

In the embodiment of the present application, the target RRM relaxation measurement strategy may be an RRM relaxation measurement strategy corresponding to the RRM relaxation measurement scenario N after the handover. As shown in Table 3 below, it is an exemplary correspondence table between RRM relaxation measurement scenarios and RRM relaxation measurement strategies.

table 3

It should be noted that in Table 3, the RRM relaxation measurement strategy M is the strategy corresponding to the RRM relaxation measurement scenario M in Table 1, and the RRM relaxation measurement strategy N is the strategy corresponding to the RRM relaxation measurement scenario N in Table 2. Table 3 only lists 4 possible RRM relaxation measurement strategies corresponding to the RRM relaxation measurement scene N (that is, the switched RRM relaxation measurement scene) after the terminal switches from the RRM relaxation measurement scene M to the RRM relaxation measurement scene N. However, the types and numbers of RRM relaxation measurement strategies corresponding to the switched RRM relaxation measurement scenarios in the embodiment of the present application are not limited. For example, after the terminal switches from the RRM relaxation measurement scenario M to the RRM relaxation measurement scenario N, the terminal may perform the RRM relaxation measurement at a normal measurement interval within a preset time period, and execute the RRM relaxation measurement strategy N after the preset time period. It should be understood that the normal measurement interval here is that the measurement interval corresponding to the RRM relaxation measurement is relatively speaking, and the normal measurement interval is smaller than the measurement interval corresponding to the RRM relaxation measurement.

In order to facilitate understanding, the following describes the specific adjustment method of the RRM relaxation measurement strategy in combination with the different situations of the specific handover scenarios of the terminal. In the following introduction, the terminal switches from the RRM relaxation measurement scenario M to the RRM relaxation measurement scenario N as an example.

In the first possible implementation manner, the terminal switches from the RRM relaxation measurement scenario M to the RRM relaxation measurement scenario N, and the terminal can directly switch from the RRM relaxation measurement strategy M to the RRM relaxation measurement strategy N to perform the RRM relaxation measurement. That is, the target RRM relaxation measurement strategy is the measurement strategy N corresponding to the measurement scene N after the handover. The following introduces the possible target RRM relaxation measurement strategy under different circumstances of several measurement scene switching.

In the first example, the RRM relaxation measurement scenario M is the aforementioned measurement scenario one, the RRM relaxation measurement scenario N is the aforementioned measurement scenario three, and the target RRM relaxation measurement strategy may be the aforementioned strategy 3. That is, the terminal switches from a high energy consumption measurement scene to a low energy consumption measurement scene, and the terminal can directly execute a low energy consumption strategy. In other words, the terminal switches from a high energy consumption measurement scenario to a low energy measurement scenario, and the terminal switches from a measurement strategy corresponding to a high energy consumption measurement scenario (also referred to as a high energy measurement strategy in this article) to a measurement corresponding to a low energy measurement scenario Strategies (also referred to as low energy consumption measurement strategies in this article). This solution can reduce the number of RRM measurements and save the power consumption of the terminal to the greatest extent.

When the terminal switches from measurement scenario 1 to measurement scenario 3, that is, the terminal may initially be at the edge of the cell, but because the terminal moves at a low speed, it may be far away from the edge of the cell, that is, the terminal is not at the edge of the cell and the terminal moves at a low speed. In this case, the terminal can directly execute strategy 3. Since strategy 3 is not to perform the RRM measurement of the neighboring cell, it can save the power consumption of the terminal to the greatest extent.

In the second example, the RRM relaxation measurement scenario M is the aforementioned measurement scenario 3, the RRM relaxation measurement scenario N is the aforementioned measurement scenario 1, and the target RRM relaxation measurement strategy may be the aforementioned strategy 1. That is, the terminal switches from a low energy consumption measurement scene to a high energy consumption measurement scene, and the terminal can directly switch from a low energy consumption measurement strategy to a high energy consumption measurement strategy. This scheme can guarantee the communication performance of the terminal to the greatest extent.

When the terminal switches from measurement scenario 1 to measurement scenario 3, that is, the terminal is not at the edge of the cell, and the terminal moves at a low speed, after a period of time, although the moving speed of the terminal is still low, the terminal may be at the edge of the cell. In this case, the terminal can directly execute strategy 1. That is, the RRM measurement is performed on the neighboring cell in time, so the communication performance of the terminal can be guaranteed to the maximum.

In the third example, the RRM relaxation measurement scenario M is the aforementioned measurement scenario two, the RRM relaxation measurement scenario N is the aforementioned measurement scenario three, and the target RRM relaxation measurement strategy is the aforementioned strategy 3. Similar to the first example, this solution can also reduce the number of RRM measurements and save the power consumption of the terminal to the greatest extent.

The terminal switches from measurement scenario 2 to measurement scenario 3, that is, the terminal is not at the edge of the cell initially, and the moving speed of the terminal is faster, and then the moving speed of the terminal is lower, but the terminal has not moved to the edge of the cell in the end. In this case, the terminal can directly execute strategy 3. Since strategy 3 is not to perform the RRM measurement of the neighboring cell, it can save the power consumption of the terminal to the greatest extent.

In the fourth example, the RRM relaxation measurement scenario M is the aforementioned measurement scenario 3, the RRM relaxation measurement scenario N is the aforementioned measurement scenario 2, and the target RRM relaxation measurement strategy is the aforementioned strategy 2. Similar to the second example, this solution can also maximize the terminal's communication performance.

When the terminal switches from measurement scenario 3 to measurement scenario 2, that is, the terminal is not at the edge of the cell, and the terminal moves at a low speed, after a period of time, although the moving speed of the terminal is still low, the terminal may be at the edge of the cell. In this case, the terminal can directly execute strategy 2. That is, the RRM measurement is performed on the neighboring cell in time, so the communication performance of the terminal can be guaranteed to the maximum.

In the fifth example, the RRM relaxation measurement scene M is the aforementioned measurement scene 1, and the RRM relaxation measurement scene N is the aforementioned measurement scene 2. If strategy 1 consumes more energy consumption of the terminal than strategy 2, then the target RRM relaxation measurement strategy can be strategy 2 to save the energy consumption of the terminal as much as possible. If strategy 1 can better guarantee the communication performance of the terminal than strategy 2, then the target RRM relaxation measurement strategy can be strategy 1 to maximize the communication performance of the terminal.

In the sixth example, the RRM relaxation measurement scene M is the aforementioned measurement scene two, and the RRM relaxation measurement scene N is the aforementioned measurement scene one. If strategy 2 needs to consume more energy consumption of the terminal compared to strategy 1, then the target RRM relaxation measurement strategy is the aforementioned strategy 1, in order to save energy consumption as much as possible. If strategy 2 can better guarantee the communication performance of the terminal than strategy 1, then the target RRM relaxation measurement strategy can be strategy 2 to maximize the communication performance of the terminal.

In the second possible implementation manner, after the terminal switches from the RRM relaxation measurement scenario M to the RRM relaxation measurement scenario N, the terminal first executes an RRM relaxation measurement strategy for a period of time, and then executes the RRM relaxation measurement strategy N. That is, the target RRM relaxation measurement strategy is to first execute an RRM relaxation measurement strategy within a period of time, and then execute the RRM relaxation measurement strategy N. The RRM relaxation measurement strategy that is executed first within a period of time can be considered as an over-relaxation measurement. In other words, compared to the aforementioned terminal switching directly from the RRM relaxation measurement strategy M to the RRM relaxation measurement strategy N, this solution transitions to the RRM relaxation measurement strategy N through the transition relaxation measurement strategy. This solution can try to balance the energy consumption requirements of the terminal and the communication performance requirements of the terminal.

The over-relaxation measurement strategy can be the RRM relaxation measurement strategy M, or it can be a strategy different from the RRM relaxation measurement strategy M. It should be understood that the value of the measurement parameter (for example, measurement interval, etc.) of the excessive relaxation measurement strategy is between the value corresponding to the RRM relaxation measurement strategy M and the value corresponding to the RRM relaxation measurement strategy N. The terminal switches from a low energy consumption measurement scene to a high energy consumption measurement scene, and the terminal can transition to a high energy consumption measurement strategy. The terminal switches from a high energy consumption measurement scenario to a low energy measurement scenario, and the terminal can also transition to a low energy measurement strategy. According to the difference between RRM relaxation measurement scenario M and RRM relaxation measurement scenario N, the target RRM relaxation measurement strategy may include any of the following strategies:

In the first example, the RRM relaxation measurement scenario M is the aforementioned measurement scenario 3, the RRM relaxation measurement scenario N is the aforementioned measurement scenario 1, and the target RRM relaxation measurement strategy can be the execution of strategy 3 within the first preset time period T1. Strategy 1 is executed after a preset period of time T1. That is, the transitional relaxation measurement strategy is strategy 3.

It should be understood that when the terminal moves to the edge of the cell at a low speed, it may move to the edge of the cell. In this case, although strategy 3 is compared with strategy 1 and strategy 2, it can meet the energy-saving requirements of the terminal to the greatest extent. However, in order to ensure the communication performance of the terminal, when the terminal switches from measurement scenario 3 to measurement scenario 1, due to the low speed of the terminal, it is possible that the terminal has not moved to the edge of the cell within a period of time (for example, the first preset duration T1). During this period of time, the terminal implements strategy 3, which can save the energy consumption of the terminal as much as possible. After this period of time, the terminal may move to the edge of the cell. At this time, the terminal executes strategy 1 to ensure the communication performance of the terminal as much as possible.

It should be noted that the first preset duration T1 may be predefined by a protocol or configured by a network device, and the terminal is notified of the value of the first preset duration T1. In some embodiments, the first preset duration T1 may be a value in the range of 10ms-20ms, such as 10ms, 15ms, 20ms, etc. The embodiment of the present application does not limit the specific value of the first preset duration T1.

As an alternative solution of the first example, the target RRM relaxation measurement strategy may be to perform RRM measurement in a first preset time period T1 according to a preset first measurement method, and then perform RRM measurement after the first preset time period T1. Strategy 1. That is, the over-relaxation measurement strategy is the first measurement method.

The preset first measurement method can be determined according to the actual needs of the terminal. In some embodiments, the terminal needs to give priority to ensuring communication performance, and the preset first measurement method may be to not use RRM relaxation measurement (hereinafter referred to as measurement method 1). For example, the preset first measurement method may be to perform RRM measurement on all neighboring cells according to the preset measurement interval within the first preset duration T1. The measurement interval may be the measurement interval corresponding to the normal RRM measurement method. It should be understood that the The normal RRM measurement method is relative to the RRM relaxation measurement. The RRM measurement before the concept of RRM relaxation measurement can be regarded as normal RRM measurement, for example, the measurement interval when the measurement relaxation is not performed.

In some embodiments, the terminal needs to take into account both communication performance and energy consumption, so a certain measurement parameter corresponding to the preset first measurement method has a larger value (hereinafter referred to as measurement method 2). For example, the measurement interval corresponding to the preset first measurement mode is located between the measurement interval corresponding to the normal RRM measurement mode and the measurement interval corresponding to the RRM relaxed measurement strategy. For another example, the number of neighboring cells to be tested corresponding to the preset first measurement method is between the number of neighboring cells to be tested corresponding to the normal RRM measurement method and the number of neighboring cells to be tested corresponding to the RRM relaxed measurement strategy. Or the number of frequency points to be measured in the neighboring cell to be measured corresponding to the preset first measurement method is between the number of frequency points to be measured corresponding to the normal RRM measurement method and the number of frequency points to be measured corresponding to the RRM relaxed measurement strategy.

In other embodiments, the terminal needs to take into account both communication performance and energy consumption, so the preset first measurement mode of multiple measurement parameters (measurement interval, number of measurement neighbors, number of measured frequency points, etc.) The values of at least two) may be located between the parameters corresponding to the measurement strategy M and the measurement strategy N (hereinafter referred to as measurement mode 3). For example, the measurement interval corresponding to the preset first measurement method is located between the measurement interval of the RRM measurement strategy M and the measurement interval of the RRM measurement strategy N, and the number of measurement neighbors corresponding to the preset first measurement method is located in the RRM measurement. Strategy M measures the number of neighboring cells and RRM measurement strategy N measures the number of neighboring cells. For another example, the measurement interval corresponding to the preset first measurement method is located between the measurement interval of the RRM measurement strategy M and the measurement interval of the RRM measurement strategy N, and the measurement interval of the RRM measurement strategy M is switched to the RRM in an increment or decrement manner. Measurement interval for measurement strategy N. The number of frequency points of the measurement neighboring cell corresponding to the preset first measurement method can also be located between the number of frequency points of the RRM measurement strategy M and the number of frequency points of the RRM measurement strategy N to measure the neighboring cells, so as to pass The method of increasing or decreasing is switched from the number of frequency points of the RRM measurement strategy M to the number of frequency points of the RRM measurement strategy N. It should be noted that the types of measurement parameters of the preset first measurement method are not limited here. It should be understood that the value of the measurement parameter of the preset first measurement mode may be the average value of the value of the measurement parameter corresponding to multiple measurement strategies (for example, the three measurement strategies in Table 2 above). The RRM measurement is performed through the preset first measurement mode, without frequent switching between RRM measurement strategies, thereby avoiding the increased energy consumption of frequent switching, and also taking into account the energy consumption requirements of the terminal and the communication performance requirements.

In still other embodiments, some measurement parameters (measurement interval, number of measurement neighbors, number of measured frequency points, etc.) of the preset first measurement mode are variable within a period of time. For example, the initial values of these measurement parameters and the adjustment factors (for example, the increment range, the number of increments, or the decrement range, the number of decrements) can be preset, so that the terminal can adjust the initial values of the measurement parameters according to the adjustment factor. For example, the preset first measurement method may be that within the first preset duration T1, the terminal sequentially decreases the initial measurement interval according to the decrease amplitude, and performs the RRM measurement according to the decreased measurement interval. It should be understood that the initial measurement interval is greater than the first measurement interval corresponding to strategy 1, and the measurement interval after the initial measurement interval is decremented within the first preset duration T1 is greater than or equal to the first measurement interval corresponding to strategy 1. Since the RRM measurement is still performed within the first preset duration T1, the communication performance of the terminal can be ensured as much as possible, and the measurement interval for performing RRM measurement within the first preset duration T1 is successively decreased, then the first preset duration T1 The number of internal measurements is reduced, so the energy consumption of the terminal can be saved as much as possible.

In the second example, the RRM relaxation measurement scenario M is the aforementioned measurement scenario 1, and the RRM relaxation measurement scenario N is the aforementioned measurement scenario 3. The target RRM relaxation measurement strategy can be to execute strategy 1 within the second preset duration T2, and in the first 2. Strategy 3 is executed after the preset time period T2. When the terminal moves at a low speed, the terminal may be located at the edge of the cell for a period of time, and then the terminal moves away from the edge of the cell. In this case, during this period of time, strategy 1 can be executed to ensure the communication performance of the terminal as much as possible. Then implement strategy 3, which can save the energy consumption of the terminal.

It should be understood that, similar to the first preset duration T1, the second preset duration T2 may be predefined by a protocol or configured by a network device. The second preset duration T2 may be the same as the first preset duration T1, or may be different from the first preset duration T1.

As an alternative solution of the second example, the target RRM relaxation measurement strategy may be to perform RRM measurement in a second preset time period T2 according to a preset second measurement method, after the second preset time period T2 Then implement strategy 3.

The preset second measurement method may also be determined according to the actual needs of the terminal. For example, the preset second measurement method may be the aforementioned measurement method 1, measurement method 2, or measurement method 3, etc., for details, please refer to the aforementioned preset measurement method. The introduction of the first measurement method is not repeated here.

For example, the measurement interval corresponding to the preset second measurement mode is variable within a period of time. For example, the initial value of the measurement interval, as well as the increment range, the number of increments, or the decrement range, and the number of decrements can be preset.

In some embodiments, the preset measurement manner may be that within the second preset duration T2, the terminal sequentially decreases the initial measurement interval according to the decreasing amplitude to perform RRM measurement. It should be understood that the initial measurement interval is greater than the first measurement interval corresponding to strategy 1, and the measurement interval of the initial measurement interval after decrementing times within the second preset duration T2 is greater than or equal to the first measurement interval corresponding to strategy 1. Since the RRM measurement is still performed during the second preset duration T2, the communication performance of the terminal can be ensured as much as possible, and the measurement interval for performing RRM measurement within the second preset duration T2 is successively decreased, then the second preset duration T2 The number of internal measurements is reduced, so the energy consumption of the terminal can be saved as much as possible.

In other embodiments, the preset measurement manner may be that within the second preset duration T2, the terminal sequentially increases the initial measurement interval according to the increasing amplitude to perform the RRM relaxation measurement. It should be understood that the initial measurement interval is smaller than the first measurement interval corresponding to strategy 1, and the measurement interval after the initial measurement interval is incremented times within the second preset duration T2 is less than or equal to the first measurement interval corresponding to strategy 1. Since the RRM measurement is still performed at a smaller measurement interval within the second preset duration T2, the communication performance of the terminal can be further ensured.

It should be understood that the value of the measurement parameter corresponding to the preset second measurement method and the value of the measurement parameter corresponding to the preset first measurement method may be the same or different.

In the third example, the RRM relaxation measurement scenario M is the foregoing measurement scenario 3, the RRM relaxation measurement scenario N is the foregoing measurement scenario 2, and the target RRM relaxation measurement strategy can be the execution of the foregoing strategy 3 for the third preset time period T3. 3. After the preset time period T3, the aforementioned strategy 2 is executed.

It should be understood that during the movement of the terminal, the moving speed of the terminal may become faster, but it takes a certain time for the terminal to move to the edge of the cell. Therefore, when the terminal switches from measurement scenario 3 to measurement scenario 2, the terminal can execute strategy 3 first and then execute strategy 2 within a period of time (for example, the third preset duration T3), which can further save energy consumption of the terminal.

As an alternative solution of the third example, the target RRM relaxation measurement strategy may be to perform RRM measurement in the second preset time period T2 according to the preset third measurement method, and then perform RRM measurement after the second preset time period T2. Execution strategy 2.

Similar to the alternative solution of the second example, the preset third measurement method can be determined according to the actual needs of the terminal. In some embodiments, the preset third measurement method may be the aforementioned preset measurement method 1 or the preset measurement method 2 or the preset measurement method 3, etc. For details, please refer to the alternative of the aforementioned second example. Scheme, I won’t go into details here.

For example, the measurement interval corresponding to the preset third measurement method is variable within a period of time. For example, the initial value of the measurement interval, as well as the increment range, the number of increments, or the decrement range, and the number of decrements can be preset.

In some embodiments, the preset measurement method may be that within the third preset duration T3, the terminal sequentially decreases the initial measurement interval according to the decrease amplitude, and performs RRM measurement according to the decreased measurement interval. It should be understood that the initial measurement interval is greater than the second measurement interval corresponding to strategy 2, and the measurement interval after the initial measurement interval is decremented after decrementing times within the third preset duration T3 is greater than or equal to the second measurement interval corresponding to strategy 2. Since the RRM measurement is still performed in the third preset time period T3, the communication performance of the terminal can be ensured as much as possible, and the measurement interval for performing the RRM measurement in the third preset time period T3 is successively decreased, then in the third preset time period T3 The number of internal measurements is reduced, so the energy consumption of the terminal can be saved as much as possible.

It should be understood that the value of the measurement parameter corresponding to the preset third measurement method and the value of the measurement parameter corresponding to the preset first measurement method may be the same or different. It should be noted that, similar to the first preset duration T1, the third preset duration T3 may be predefined by a protocol or configured by a network device. The third preset duration T3 may be the same as the first preset duration T1, or may be different from the first preset duration T1.

In the fourth example, the RRM relaxation measurement scenario M is the aforementioned measurement scenario 2 and the RRM relaxation measurement scenario N is the aforementioned measurement scenario 3, and the target RRM relaxation measurement strategy can be the execution of the aforementioned strategy 2 at the fourth preset time period T4. After the preset time period T4, the aforementioned strategy 3 is executed.

The terminal switches from measurement scenario 2 to measurement scenario 3, that is, the terminal is not at the edge of the cell initially, and the moving speed of the terminal is faster, and then the moving speed of the terminal is lower, but the terminal has not moved to the edge of the cell in the end. In this case, the terminal can execute strategy 2 for a period of time, and then execute strategy 3. Although the terminal has not been at the edge of the cell during this period of time, in order to prevent the terminal from moving faster and may move to the edge of the cell, the terminal still implements strategy 2 during this period of time to ensure the communication performance of the terminal as much as possible. After this period of time, strategy 3 is implemented, that is, the RRM measurement of the neighboring cell is not performed, which further saves the power consumption of the terminal.

As an alternative solution of the fourth example, the target RRM relaxation measurement strategy may be to perform RRM measurement in the second preset time period T2 according to a preset fourth measurement method, and then perform RRM measurement after the fourth preset time period T4. Implementation strategy 3.

Similar to the alternative solution of the second example, the preset fourth measurement method can be determined according to the actual needs of the terminal. In some embodiments, the preset third measurement method may be the aforementioned preset measurement method 1 or the preset measurement method 2 or the preset measurement method 3, etc. For details, please refer to the alternative of the aforementioned second example. Scheme, I won’t go into details here.

For example, the measurement interval corresponding to the preset fourth measurement mode is variable within a period of time. For example, the initial value of the measurement interval, as well as the increment range, the number of increments, or the decrement range, and the number of decrements can be preset. The preset measurement method may be that within the fourth preset time period T4, the terminal sequentially decreases the initial measurement interval according to the decreasing amplitude, and performs the RRM measurement according to the decreased measurement interval. It should be understood that the initial measurement interval is greater than the second measurement interval corresponding to strategy 2, and the measurement interval after the initial measurement interval is decremented after the decrement times within the fourth preset duration T4 is greater than or equal to the second measurement interval corresponding to strategy 2. Since the RRM measurement is still performed in the fourth preset time period T4, the communication performance of the terminal can be ensured as much as possible, and the measurement interval for performing the RRM measurement in the fourth preset time period T4 is successively decreased, then in the fourth preset time period T4 The number of internal measurements is reduced, so the energy consumption of the terminal can be saved as much as possible.

In other embodiments, the preset measurement method may be that within the fourth preset duration T4, the terminal sequentially increments the initial measurement interval according to the increment amplitude, and performs RRM measurement according to the incremented measurement interval. It should be understood that the initial measurement interval is smaller than the second measurement interval corresponding to strategy 2, and the measurement interval after the initial measurement interval is incremented after the number of increments within the fourth preset duration T4 is less than or equal to the second measurement interval corresponding to strategy 2. Since the RRM measurement is still performed at a small measurement interval within the fourth preset time period T4, the communication performance of the terminal can be further ensured.

It should be understood that the value of the measurement parameter corresponding to the preset fourth measurement mode and the value of the measurement parameter corresponding to the preset first measurement mode may be the same or different. It should be noted that, similar to the first preset duration T1, the fourth preset duration T4 may be predefined by a protocol or configured by a network device. The fourth preset duration T4 may be the same as the first preset duration T1, or may be different from the first preset duration T1.

In the fifth example, the RRM relaxation measurement scene M is the aforementioned measurement scene 1, and the RRM relaxation measurement scene N is the aforementioned measurement scene 2. If strategy 1 consumes more energy consumption of the terminal than strategy 2, then the target RRM relaxation measurement strategy can be strategy 2, which saves the energy consumption of the terminal to the greatest extent. If strategy 1 needs to consume less energy consumption of the terminal than strategy 2, then the target RRM relaxation measurement strategy can be to execute strategy 1 at the fifth preset time period T5, and then execute the aforementioned strategy 2, because in the fifth preset Strategy 1 is executed within the duration T5, so the energy consumption of the terminal can be saved as much as possible; alternatively, the target RRM relaxation measurement strategy can be to execute RRM in the fifth preset duration T5 with a preset measurement interval and a preset decreasing range. Measure, and execute strategy 2 after the fifth preset time period T5. It should be understood that the preset measurement interval is greater than the second measurement interval, and after the fifth preset duration T5, the preset measurement interval is still greater than or equal to the second measurement interval after being decremented. Since the RRM measurement is performed at a measurement interval greater than the second measurement interval within the fifth preset time period T5, the energy consumption of the terminal can be further saved. Wherein, similar to the first preset duration T1, the fifth preset duration T5 may be predefined or set by the network device. The embodiment of the present application does not limit the value of the fifth preset duration T5.

In the sixth example, the RRM relaxation measurement scene M is the aforementioned measurement scene two, and the RRM relaxation measurement scene N is the aforementioned measurement scene one. If strategy 2 needs to consume more energy consumption of the terminal than strategy 1, then the target RRM relaxation measurement strategy can be strategy 1, which saves the energy consumption of the terminal to the greatest extent. If strategy 2 requires less energy consumption of the terminal than strategy 1, then the target RRM relaxation measurement strategy can be to execute strategy 2 at the sixth preset time period T6, and then execute the aforementioned strategy 1, because in the sixth preset Strategy 2 is executed within the duration T6, so the energy consumption of the terminal can be saved as much as possible; alternatively, the target RRM relaxation measurement strategy can be to execute RRM in the sixth preset duration T6 at a preset measurement interval and in a manner that decreases the preset decrement amplitude. Measure, and execute strategy 1 after the sixth preset time period T6. It should be understood that the preset measurement interval is greater than the first measurement interval, and after the sixth preset duration T6, the preset measurement interval is still greater than or equal to the first measurement interval after decrementing. Since the RRM measurement is performed at a measurement interval greater than the first measurement interval within the sixth preset time period T6, the energy consumption of the terminal can be further saved. Wherein, similar to the first preset duration T1, the sixth preset duration T6 may be predefined or set by the network device. The embodiment of the present application does not limit the value of the sixth preset duration T6. The sixth preset duration T6 may be the same as the fifth preset duration T5 or may be different.

As in the foregoing possible implementation manner 1 or implementation manner 2, the terminal switches from the RRM relaxation measurement scenario M to the RRM relaxation measurement scenario N, and the terminal can directly switch from the RRM relaxation measurement strategy M to the RRM relaxation measurement strategy N, or transition to RRM relax measurement strategy N. The terminal can determine which way to switch the RRM relaxation measurement strategy according to actual requirements, such as the energy-saving requirements of the terminal and/or the communication performance of the terminal.

It should be understood that the energy saving requirement of the terminal and/or the communication performance of the terminal can be understood as a handover criterion for the terminal to determine the handover of the RRM relaxation measurement strategy. Exemplarily, the energy saving requirement of the priority terminal is the first criterion, the communication performance of the priority terminal is the second criterion, and both the energy saving requirement of the terminal and the communication performance of the terminal are the third criterion.

In some embodiments, the terminal may determine the handover criterion to be adopted for the target RRM relaxation measurement strategy based on the type of service being performed. For example, when the terminal performs voice services, in order to ensure the quality of the call, the handover criterion may be the second criterion. In other embodiments, the terminal may determine the switching criterion to be adopted for the target RRM relaxation measurement strategy based on its own product type. For example, the terminal is a portable device (mobile phone, tablet, watch, bracelet, etc.), and energy saving should be given priority, so the switching criterion can be the first criterion. In still other embodiments, the terminal may determine the handover criterion to be adopted for the target RRM relaxation measurement strategy based on its own usage status, such as the terminal's power consumption status, movement status, network status, etc. For example, when the terminal turns on the power saving mode, the switching criterion may be the first criterion. For example, the terminal moves faster. In order to ensure the communication quality, the handover criterion may be the second criterion.

If the terminal determines the target RRM relaxation measurement strategy based on the first criterion, when the terminal switches from a high-energy measurement scenario to a low-power measurement scenario, the target RRM relaxation measurement strategy is directly switched to a low-energy measurement strategy. For example, if the terminal switches from the aforementioned measurement scenario 1 or measurement scenario 2 to measurement scenario 3, then the target RRM relaxation measurement strategy is strategy 3.

If the terminal determines the target RRM relaxation measurement strategy based on the second criterion or the third criterion, when the terminal switches from a high-energy-consumption measurement scenario to a low-energy-consumption measurement scenario, the target RRM relaxation measurement strategy may be a transition to a low-energy measurement strategy. For example, the terminal switches from the aforementioned measurement scenario 1 or measurement scenario 2 to measurement scenario 3, then the target RRM relaxation measurement strategy can be to execute, for example, strategy 1 or strategy 2 within a preset period of time, and then execute the strategy after the preset period of time. 3.

In other words, when the terminal switches from a measurement scenario with higher energy consumption to a measurement scenario with lower energy consumption, the terminal can directly execute the strategy corresponding to the measurement scenario with lower energy consumption, so as to save the energy consumption of the terminal as much as possible. Or, the terminal can transition for a period of time, and then execute the strategy corresponding to the measurement scenario with lower energy consumption, while saving the energy consumption of the terminal, try to ensure the communication performance of the terminal.

Similarly, if the terminal determines the target RRM relaxation measurement strategy based on the second criterion, when the terminal switches from a low energy consumption measurement scene to a high energy consumption measurement scene, the target RRM relaxation measurement strategy is directly switched to a high energy consumption measurement strategy. For example, if the terminal switches from the aforementioned measurement scenario 3 to measurement scenario 1 or measurement scenario 2, then the target RRM relaxation measurement strategy is strategy 1 or strategy 2.

If the terminal determines the target RRM relaxation measurement strategy based on the first criterion or the third criterion, when the terminal switches from a low-energy measurement scenario to a high-energy measurement scenario, the target RRM relaxation measurement strategy may be a transitional switch to a high-energy measurement strategy. For example, if the terminal switches from the aforementioned measurement scenario 3 to measurement scenario 1 or measurement scenario 2, then the target RRM relaxation measurement strategy can be to first execute strategy 3 within a preset time period, and then execute strategy 1 or strategy after the preset time period. 2.

When the terminal switches from a measurement scenario with lower energy consumption to a measurement scenario with higher energy consumption, the terminal directly executes the strategy corresponding to the measurement scenario with higher energy consumption to maximize the communication performance of the terminal; or, the terminal can After a transition period of time, the strategy corresponding to the measurement scenario with higher energy consumption will be executed again to save the energy consumption of the terminal as much as possible while ensuring the communication performance of the terminal.

Different from the foregoing implementation manner 1 or implementation manner 2, the terminal may also determine the target RRM relaxation measurement strategy according to the instruction of the network device. That is, as an alternative to the foregoing implementation method 1 or implementation method 2, the network device can specify the target RRM relaxation measurement scenario for the terminal. When the terminal switches from the RRM relaxation measurement scenario M to the RRM relaxation measurement scenario N, the terminal adopts the network device Specify the target RRM relaxation measurement scenario, and perform RRM relaxation measurement.

Exemplarily, S503. The network device may send instruction information to the terminal, where the instruction information is the terminal instructing the target RRM to relax the measurement strategy. It should be understood that S503 is an optional step, and therefore, it is illustrated by a dotted line in FIG. 5.

The indication information may directly indicate the target RRM relaxation measurement strategy, or indirectly indicate the target RRM relaxation measurement scenario. The following describes several possible implementations of the indication information.

Direct indication method 1: The indication information may include measurement parameters, and the measurement parameters may include, for example, one or more of the measurement interval, the number of neighboring cells to be tested, and the number of frequency points to be tested in the neighboring cells to be tested. When the terminal switches from the RRM relaxation measurement scenario M to the RRM relaxation measurement scenario N, the target RRM relaxation measurement strategy can be determined according to the measurement parameters, and the RRM relaxation measurement can be performed. In other words, the solution can directly instruct the target RRM to relax the measurement strategy. It should be understood that, in this case, the network device may send the indication information to the terminal when the terminal switches from the RRM relaxation measurement scenario M to the RRM relaxation measurement scenario N.

Exemplarily, the measurement parameter includes a measurement interval, and the terminal can perform RRM relaxation measurement on all neighboring cells according to the measurement interval according to the measurement parameter. Alternatively, the measurement parameter includes the number L of neighboring cells to be measured, and the terminal can perform RRM relaxation measurement on the L neighboring cells to be measured according to the measurement parameter. Alternatively, the measurement parameter includes the number K of subcarriers to be measured in the neighboring cell to be measured, and the terminal can perform RRM relaxation measurement on the K subcarriers of the neighboring cell to be measured according to the measurement parameter. For another example, the measurement parameter includes a measurement interval and the number L of adjacent cells to be measured, and the terminal can perform RRM relaxation measurement on L adjacent cells to be measured according to the measurement interval according to the measurement parameter, and so on.

It should be understood that the measurement parameter may be determined by the network device according to the power consumption requirement of the terminal and the moving speed of the terminal, so the energy saving requirement of the terminal and the communication performance of the terminal can be considered.

In some embodiments, the measurement parameter may be carried in system information (SI), that is, the network device may broadcast the SI carrying the measurement parameter, and send the measurement parameter to the terminal. For example, the measurement parameters may be carried in a system information block (system information block, SIB), such as SIB2. Among them, the measurement parameters can be carried in information elements defined in SIB2, for example, cell reselection information (cellReselectionInfoCommon) information element in SIB2, or speed movement state parameter (speedStateReselectionPars) information element in SIB2, or other possible information elements; Alternatively, the measurement parameters can also be carried in the newly defined information element in SIB2.

In other embodiments, the measurement parameter may be carried in radio resource control (radio resource control, RRC) signaling, that is, the network device sends the measurement parameter to the terminal by sending the RRC signaling carrying the measurement parameter to the terminal.

Direct indication mode 2: The indication information is used to indicate at least one RRM relaxation measurement strategy, and the target RRM relaxation measurement strategy is a certain RRM relaxation measurement strategy among the at least one RRM relaxation measurement strategy. For example, the indication information indicates a kind of RRM relaxation measurement strategy, then the target RRM relaxation measurement strategy is this kind of RRM relaxation measurement strategy. For example, the indication information indicates multiple RRM relaxation measurement strategies, then the target RRM relaxation measurement strategy can be one of the multiple RRM relaxation measurement strategies, or at least two of the multiple RRM relaxation measurement strategies. RRM relax measurement strategy.

Exemplarily, the indication information is used to indicate the first RRM relaxation measurement strategy and/or the second RRM relaxation measurement strategy. In this case, the corresponding relationship between the switching of measurement scenarios and the RRM relaxation measurement strategy can be defined in advance as in Table 3 above. The indication information may indicate one or more RRM relaxation measurement strategies as in Table 3. It should be understood that when the indication information indicates multiple relaxation measurement strategies, the terminal starts to execute different RRM relaxation measurement strategies at different times. For example, the indication information indicates the first RRM relaxation measurement strategy and the second RRM relaxation measurement strategy, then the terminal may start to execute the first RRM relaxation measurement strategy at the first moment, and the second RRM relaxation measurement strategy at the second moment.

In some embodiments, the instruction information may further include a first moment and a second moment, where the first moment is the moment when the first RRM relaxation measurement strategy starts to be executed, and the second moment is the moment when the second RRM relaxation measurement strategy starts to be executed. time. Or the instruction information may further include a first moment and a first preset duration, where the first moment is the moment when the first RRM relaxation measurement strategy starts to be executed, and the first preset duration is the duration for executing the first RRM relaxation measurement strategy, Then, after the first preset duration, the terminal starts to execute the second RRM relaxation measurement strategy.

It should be noted that in the direct instruction method two, the network device may send instruction information to the terminal when the terminal switches the measurement scenario. If the indication information indicates multiple RRM relaxation measurement strategies, the terminal may select one or more RRM relaxation measurement strategies from the multiple RRM relaxation measurement strategies. As mentioned above, the terminal can select one or more RRM relaxation measurement strategies from these multiple RRM relaxation measurement strategies based on the handover criterion. Alternatively, the network device may also send instruction information to the terminal before the terminal switches the measurement scenario. In this case, the system can predefine the corresponding relationship as shown in Table 3 above, and after the terminal switches from one measurement scenario to another measurement scenario, it selects the corresponding RRM relaxation measurement strategy. Or, in addition to sending instruction information indicating at least one RRM relaxation measurement strategy to the terminal, the network device also informs the terminal to execute the target relaxation measurement strategy indicated by the instruction information when a certain measurement scenario switch is satisfied.

In an indirect indication manner, the indication information may include a switching criterion by which the terminal switches the RRM relaxation measurement strategy, and the switching criterion corresponds to the target RRM relaxation measurement strategy. In other words, the scheme indirectly indicates the target RRM relaxation measurement strategy through the switching criterion. The switching criterion may include the aforementioned first criterion, second criterion or third criterion.

In some embodiments, the correspondence between the switching criterion and the RRM relaxation measurement strategy under the measurement scene switching may be predefined. After receiving the instruction information, the terminal can determine the RRM relaxation measurement strategy in the corresponding measurement scenario according to the correspondence relationship, and then determine the target RRM relaxation measurement strategy through the switched scenario when the scene is switched.

In other embodiments, the corresponding relationship between the switching criterion and the switch of the RRM relaxation measurement scenario, and the corresponding relationship between the switch of the RRM relaxation measurement scenario and the RRM relaxation measurement strategy can be predefined. After receiving the instruction information, the terminal can determine the target RRM relaxation measurement strategy according to the two corresponding relationships.

In a possible implementation manner, similar to the direct indication manner 1, the indication information may also be carried in the SIB2 defined cell or RRC signaling.

In some embodiments, the indication information may include a switching criterion. For example, the indication information occupies m bits, and a value of m bits corresponds to a switching criterion. For example, the indication information occupies 2 bits, when the value of 2 bits is 0, the indication information indicates the first criterion, when the value of 2 bits is 1, the indication information indicates the second criterion, and so on.

In other embodiments, the indication information may indicate the priority of the terminal service, and the switching criterion is indicated by the priority. For example, the service with the highest priority is defined and the communication performance of the terminal is guaranteed first, that is, the service with the highest priority corresponds to the second criterion; relatively speaking, the service with the lowest priority corresponds to the first criterion. The terminal can determine the handover criterion according to the priority of the service notified by the network device, and then determine the target RRM relaxation measurement strategy.

In the embodiments of the present application, in order to take into account the power consumption requirements of the terminal and the communication performance requirements, the corresponding relationship between the switching of the RRM relaxation measurement scene and the RRM relaxation measurement strategy is specified for the situation where the terminal switches the RRM relaxation measurement scenario. Therefore, after the terminal switches the RRM relaxation measurement scenario, it can determine the target RRM relaxation measurement strategy according to the corresponding relationship, and execute the RRM measurement. Alternatively, the network device may instruct the terminal to switch the RRM relaxation measurement scenario for the terminal, and then the target RRM relaxation measurement strategy to be adopted.

●Relaxation of measurement/cell identification/evaluation requirements

In RAN4 three scenarios are listed,

--#1:Low mobility scenario

--#2:Not in cell-edge scenario

--#3:Low-mobility+Not in cell-edge scenario

It was agreed in the last RAN4 meeting[1] that the RRM measurement relaxation will be applied for scenario#1 and#2.

Regarding how to relax the measurement, the power consumption results were discussed during SI phase. The details of simulation assumption are in annex which is captured in TS38.840. The simulation results are given3 in the Table. gain when extending measurement periodicity.

Table 1. Power saving gain when extending measurement periodicity

To	DRX＝0.32DRX=0.32	DRX＝0.64DRX=0.64	DRX＝1.28sDRX=1.28s	DRX＝2.56DRX=2.56
N＝4N=4	27.9％27.9%	24.75％24.75%	19.7％19.7%	14.2％14.2%
N＝8N=8	32.5％32.5%	28.628.6	23.0％23.0%	16.5％16.5%

It can be observed that extending N times of measurement interval can bring obvious power saving gain. When the DRX is larger, the gain got from 8 times extension compared with 4 times may be different out of standing network not standing different the flexible method is that the extension factor is configured by network. For example, network can configure different relaxation factor for different scenario. Or the relaxation factor can also consider the UE mobility factor degree or location etc. {2,8}.

Proposal 1: The extension factor for relaxed measurement can be configured by network for scenario #1 and#2.

In the last meeting, RAN2 sent an LS to RAN4[2]. The agreement was duplicated as below,

RAN2 has aggregated that network indicators option a or option b. For option a, it was already already agreed at RAN4#93 meeting that UE is not required to meet the intra-frequency and inter-frequency neigh-frequency and inter-frequency measures #3 the UE behavior is clear.

For option b when network configures the parameters of both low mobility and not-at-cell-edge criteria, UE can perform relaxation when either low mobility or not-at-cell-edge criteria is fulfilled. If both don criteria are fulfilled. 't think that UE shall stop measurement in this case. Since network indicators option b to UE, it means that network expects relaxation measurement and expects the measurement results reported by UE Otherwise to the network society. satisfied, UE can choose any one, it is up to UE implementation.

Proposal 2: When network configures the parameters of both low mobility and not-at-cell-edge criteria,

-if network indicates option a,UE stops intra-frequency and inter-frequency neighbour cell measurements when both criteria are fulfilled.

-if network indicates option b,UE performs corresponding relaxed measurement according to which criteria is met.If both criteria are satisfied,it is left to UE implementation to choose one (either low mobility or not-at cell-edge)and perform the corresponding relaxed measurements.

In NB Iot, the following relaxed monitoring measurement rules are specified in TS 36.304. The time interval since the last measurement for cell reselection is defined as 24 hours.

In power saving, if both criteria are satisfied and option a is indicated by network, UE will stop intra-frequency and inter-frequency neighbour cell measurements. In this case the interval since last measure for cell reselectionlys the hall before 24 hours. is not suitable for power saving UE. This value shall consider the network deployment, propagation, environment, UE mobility direction, UE speed, UE location and etc. Too long interval may impact UE mobility performance and power reduction short value the will. Generally we think time interval for measurement relaxation (stop measurements) since last measurement for cell reselection is minutes level.

Proposal 3: Time interval for measurement relaxation(stop measurements) since last measurement for cell reselection is minutes level.

●RRM measurement relaxation for inter-frequency layer with higher priority

RAN4 discussed the RRM measurement for inter-frequency layer with higher priority during last meeting. Three options are captured in[1]as following.

In parallel, RAN2 was discussing the same issue as well[2].

In current specification if Srxlev>S _{nonIntraSearchP} and Squal>S _{nonIntraSearchQ} then the UE shall search for inter-RAT E-UTRAN layers of higher priority at least every T _{higher_priority_search} where T _{higher_priority_search} ＝(60*N _layers )seconds.The requirements for this case is already very relaxed, so the benefit of further relaxation is negligible.

For the case where Srxlev<S _{nonIntraSearchP} or Squal<S _{nonIntraSearchQ} ,the UE behaviour is to perform measure inter-frequency layers of higher,equal or lower priority layers.In the current specification,the measurement requirements for higher,equal or lower priority layers is the same in this case.In power saving scenario,the power saving benefit can be foreseen if the measurement of higher priority layers is relaxed(the gain is shown in table 1).In addition,the measurement result validity due to the measurement relaxation on higher priority is not a big issue.Since the power saving trigger criteria is specified for low mobility or not-at-cell edge scenario,in both cases,there is no strong command of obtaining fast measurement results.However if different priority layers( high,equal and lower)have the same requirements of measurement,this is contradictory with the motivation of introduction of different priority layers.So S _rxlev ≤S _{nonIntraSearchP} or S _qual ≤S _{nonIntraSearchQ} ,the rel axed requirement for the frequency layer of higher priority can use different relaxed measurement requirement as those for the frequency layer of equal/lower priority.

Proposal 4:When Srxlev>SnonIntraSearchP and Squal>SnonIntraSearchQ,no relaxation of the current measurement delay requirement is expected for inter-frequency measurement with higher priority.When Srxlev≤SnonIntraSearchP or Squal≤SnonIntraSearchQ, the relaxed requirement for the frequency layer of higher priority can use the different relaxed measurement requirement as those for the frequency layer of equal/lower priority.

●Reducing the frequency layer number

Paging occasion is essential and can not be missed from UE point of view. In theory, UE can perform intra-frequency measurement during the paging occasion, which means that intra-frequency measurement doesn’t introduce extra power.

For inter-frequency measurement, UE needs to wake up additionally during DRX-OFF in order to avoid the degradation on the paging reception. As we know, the measurement requirements for inter-frequency are scaling with the frequency that it’s normalized number. power is not increased when multiple inter-frequency layers are configured.

Proposal 5: Reducing the inter-frequency layers for measurement in idle mode can not bring power saving gain.

●Impact on early measurement reporting

Early measurement reporting is introduced in CA/DC enhancement. The intention of EMR is to fasten the CA/DC setup when UE enters to connected mode. If UE is in power saving mode, the normal to impact. be discussed separately.

In scenario#1 and#2, the relaxation measurement shall be performed. In our understanding, EMR is not an urgent functionality and the measurement result derived from the relaxation measurement on the carriers indicated by the EMR can still be configured by EMR.

Proposal 6: In scenario#1 and#2, the measurement result derived from relaxation measurement can still be applied in EMR.

In scenario#3, UE may stop the neighbor cell measurements when UE is in power saving mode. However, if the UE was configured with EMR configuration in RRC release as well, UE has no information when UE is in power saving mode. enter RRC connected mode. For this case UE may need to establish CA or DC due to service load. It is reasonable to perform EMR measurement. Considering the power saving, UE can perform relaxation measurement.

Proposal 7:In scenario#3,when UE is configured with EMR,UE will perform relaxation measurements.

●RRM impact due to cross-slot scheduling power saving technology

RAN1 is discussing the cross-slot scheduling power saving during last meeting. The framework of the impact the BWP switching is basically shown in the followings (duplicated from RAN1 chairman notes).

Thus in RAN4 it is no need to discuss extending the BWP switching delay. In other words, the DCI based BWP switching delay requirements in RAN4 is unchanged.

Proposal 8: The DCI based BWP switching delay requirements in RAN4 is not impacted by cross-slot scheduling.

This contribution provides the discussion on measurement relaxation in power saving. The proposals are provided as below:

Table 18: UE power consumption model for FR1

Table 22: UE power consumption for the RRM measurements

Table 24: UE power consumption of the combined neighbor cell measurements and cell search

There are three main scenarios for relaxing the measurement/cell identification/evaluation requirements.

#1: Low mobility scene

#2: Not used in cell edge scenarios

#3: Low speed + non-edge scene

Applicability of RRM relaxation method to scenario #1 and scenario #2:

scene 1:

Agreement-RRM measurement relaxation and lengthening

Scene two:

Agreement-RRM measurement relaxation and lengthening

Measurement interval scaling factor FFS

Option 1: Fixed value

Scene #1 and Scene #2 have the same FFS value

The individual values of scene #1 and scene #2 are for further study

Option2: network configurable value

Applicability of the RRM relaxation method to scenario #1 and scenario #2: How to relax the measurement is discussed, and the power consumption results in the SI phase are discussed. The details of the simulation assumptions are in the attachment of TS38.840. The simulation results are shown in Table 1 [3]. Table 1 shows the power saving gain when the measurement period is extended.

Table 1. Power saving gain for extending the measurement period

It can be seen that extending the measurement interval by N times can bring significant energy-saving gains. When the DRX is larger, the gain of 8 times expansion is less obvious than that of 4 times expansion. Since the network may have different preferences in different scenarios, a flexible method is to configure the expansion factor according to the network. For example, the network can configure different relaxation factors for different scenarios. Alternatively, the relaxation factor may also consider the degree of movement or location of the UE. The value range of relaxation factor is {2,8}. Recommendation 1: For scenarios #1 and #2, the expansion factor can be loosely measured according to the network configuration. In the last meeting, RAN2 sent an LS to RAN4[2]. The agreement is reproduced as follows:

RAN2 discussed the issues related to NR energy-saving RRM measurement, and reached the following agreement: 1. The network side broadcasts the corresponding relaxation trigger criterion parameter, and turns on the RRM measurement relaxation feature. 2. When the network is configured with low mobility and non-edge criterion parameters at the same time. The UE can perform measurement relaxation according to one of the following options indicated by the network:-Option a: The UE uses a low mobility standard and a non-cell edge standard, that is, the UE can perform relaxation only if these two conditions are met at the same time. The specific relaxation behavior depends on the discussion and decision of RAN4;-Option b: UE uses low mobility standard or non-cell edge standard (the choice can be left to the UE to realize), that is: when the low mobility or non-cell edge criterion is met, The UE can relax. The detailed relaxation behavior is the same as when the network is only configured with standards

RAN2 has agreed to the network indicating option a or option b. For option a, it has been agreed in the RAN4#93 meeting that the UE does not need to meet the same-frequency and inter-frequency adjacent cell measurement requirements of scenario #3. Therefore, the behavior of the UE is clear. For option b, when the network configures the parameters of low mobility and non-cell edge criteria at the same time, the UE can perform relaxation when the low mobility or non-cell edge criteria are met. If both criteria are met, we believe that the UE will not stop measurement in this case. Since the network indicates option b to the UE, this means that the network expects to relax the measurement and expects the measurement result reported by the UE. Otherwise, the network will indicate option a to the UE. Therefore, if both criteria are met, the UE can choose either one, depending on the UE implementation.

Recommendation 2: When the network is configured with low mobility and non-edge cell standard parameters at the same time,-if the network indicates option a, when these two standards are met, the UE stops the same-frequency and inter-frequency adjacent cell measurement. -If the network indicates option b, the UE performs the corresponding loose measurement according to which conditions are met. If these two conditions are met, the UE selects one (low mobility or non-edge cell) and performs the corresponding loose measurement. In NB-IoT, the following loose delay monitoring and measurement rules are defined in TS 36.304. The time interval from the last cell reselection measurement is defined as 24 hours.

5.2.4.12.0 Loose monitoring measurement rules When the UE is required to perform intra-frequency or inter-frequency measurement according to the measurement rules in subsection 5.2.4.2 or 5.2.4.2a, the UE can choose not to perform intra-frequency or inter-frequency measurement in the following cases Measurement:-Meet the loose monitoring criteria in section 5.2.4.12.1 during TSearchDeltaP, and-Less than 24 hours have passed since the last cell reselection measurement was performed, and-The UE is selecting or reselecting to a new cell After that, at least TSearchDeltaP same-frequency or different-frequency measurements were performed.

In the power saving mode, if both conditions are met, and the network indicates option a, the UE will stop the same-frequency and inter-frequency neighbor cell measurement. In this case, the interval from the last cell reselection measurement should be considered. Obviously, 24 hours is not suitable for power saving terminals. This value should consider network deployment, propagation environment, UE moving direction, UE speed, UE location, etc. Too long a period configuration will affect the UE's mobility performance, and a too short period configuration will reduce the power saving gain. Generally speaking, we consider the time interval of measurement relaxation (stop measurement), because the last measurement of cell reselection was in the order of minutes. Recommendation 3: Starting from the last cell reselection measurement, the time interval for measurement relaxation (measurement stop) is on the order of minutes. l RRM measurement relaxation of the inter-frequency layer with higher priority RAN4 discussed the RRM measurement with higher priority in the inter-frequency layer.

"RRM measurement relax high-priority inter-frequency layer option 1:" When Srxlev>SnonIntraSearchP and Squal>SnonIntraSearchQ, for higher-priority inter-frequency measurements, it is not expected to relax the current measurement delay requirements. "When Srxlev d SnonIntraSearchP or Squal d SnonIntraSearchQ, the loose measurement requirements for the high-priority frequency layer are the same as the loose measurement requirements for the peer/low-priority frequency layer. Alternative 2: "In high-speed mobile scenarios, high priority Carrier measurement should not be relaxed (Scenario #2) Option 3: "The measurement of higher priority carriers should not be relaxed.

1. Whether the high-priority frequency point is loose or not depends on the network configuration. Regarding how to configure, further study is needed. RAN2 is discussing high-priority measurement relaxation instructions, and would like to ask RAN4 about the relaxation behavior of high-priority carriers: 1. For the situation of Srxlev>SnonIntraSearchP and Squal>SnonIntraSearchQ, if the relaxation criteria defined by RAN2 are met, does RAN4 envisage further relaxation than Higher_priority_search Measurement of higher priority carriers? 2. For the case of Srxlev<SnonIntraSearchP or Squal<SnonIntraSearchQ, if the relaxation standard defined by RAN2 is met, is there a performance or system advantage that only relaxes the measurement of the same/low priority carrier, but not the measurement of the high priority carrier?

In the current specification, if Srxlev>SnonIntraSearchP and Squal>SnonIntraSearchQ, the UE should at least search for the different system E-UTRAN layer with higher priority in each Higher_priority_search, where Higher_priority_search=(60*Nlayers) takes effect after seconds. In this case, the requirements are already very relaxed, so the benefits of further relaxation are negligible. In the case of Srxlev<SnonIntraSearchP or Squal<SnonIntraSearchQ, the UE behavior is to measure inter-frequency layers with higher, same or lower priority layers. In the current specification, the measurement requirements for high priority, equal priority, or low priority are the same in this case. In the energy-saving scenario, if the measurement of high-priority tiers is relaxed, energy-saving benefits can be foreseen (as shown in Table 1). In addition, since the measurement is relaxed to a higher priority, the validity of the measurement results is not a big issue. Because the energy saving trigger standard is designated as low.

Recommendation 4: When Srxlev>SnonIntraSearchP and Squal>SnonIntraSearchQ, do not relax the current measurement delay requirements for high-priority inter-frequency measurement. When Srxlev d SnonIntraSearchP or Squal d SnonIntraSearchQ, the loose measurement requirements for the high-priority frequency layer are different from the loose measurement requirements for the equal/low-priority frequency layer.

Reducing the number of frequency layers From the perspective of the UE, the paging opportunity is indispensable and cannot be missed. In theory, the UE can perform co-frequency measurement at the paging moment, which means that co-frequency measurement will not introduce additional large power consumption. For inter-frequency measurement, the UE needs to wake up during the DRX-OFF period to avoid a decrease in paging reception. We know that the measurement requirements for different frequencies scale with the number of frequencies. That is, when the number of inter-frequency layers is greater than one layer, the normalized power is not raised.

Recommendation 5: Reduce the number of inter-frequency layers for idle state measurement, which cannot bring energy-saving gains.

Impact on Early Measurement Reports CA/DC is enhanced to introduce the function of reporting early measurement reports. The purpose of EMR is to speed up the establishment of CA/DC when the UE enters the connected state. If the UE is in the power saving mode, it may affect the normal measurement. There are two situations that need to be discussed separately. In scenes #1 and #2, relaxation measurement should be performed. As far as we know, EMR is not an urgent function. The measurement results obtained by performing relaxation measurements on the carrier indicated by the EMR configuration can still be applied to EMR.

Proposal 6: In scenarios #1 and #2, the measurement results obtained from the relaxation measurement can still be applied to EMR. In scenario #3, when the UE is in the power saving mode, the UE can stop the neighbor cell measurement. However, if the UE also configures the EMR configuration in the RRC release, when the UE is ready to enter the RRC connected mode, the UE has no information about the neighbor cell measurement results. In this case, the UE may need to establish CA or DC due to traffic load. The EMR measurement is reasonable. Considering power saving, the UE can perform relaxation measurements.

Recommendation 7: In scenario #3, when the UE configures EMR, the UE will perform relaxation measurement. l The impact of cross-slot scheduling energy-saving technology on RRM RAN1 was discussing energy-saving cross-slot scheduling at the last meeting. The impact framework of BWP switching is basically as follows.

Summary: "If the DCI format 1_1 (or 0_1) indicates a target DL (or UL) BWP different from the activated DL (or UL) BWP. The minimum applicable scheduling offset indication field (if present in the DCI format) Indicates the minimum scheduling offset limit applied to the target BWP. Note: The specifications do not need to be changed.

Therefore, in RAN4, there is no need to discuss extending the BWP handover delay. In other words, the DCI-based BWP handover delay requirement in RAN4 remains unchanged. Recommendation 8: BWP handover delay requirements based on DCI in RAN4 are not affected by cross-slot scheduling.

This article discusses the measurement relaxation in energy saving. The proposal is as follows: Recommendation 1: For scenarios #1 and #2, the expansion factor can be loosely measured according to the network configuration.

Recommendation 2: When the network is configured with low mobility and non-edge cell standard parameters at the same time,-if the network indicates option a, when these two standards are met, the UE stops the same-frequency and inter-frequency adjacent cell measurement. -If the network indicates option b, the UE performs the corresponding loose measurement according to which conditions are met. If these two conditions are met, the UE selects one (low mobility or non-edge cell) and performs the corresponding loose measurement.

Recommendation 3: Starting from the last cell reselection measurement, the time interval for measurement relaxation (measurement stop) is on the order of minutes.

Proposal 6: In scenarios #1 and #2, the measurement results obtained from the relaxation measurement can still be applied to EMR.

Recommendation 7: In scenario #3, when the UE configures EMR, the UE will perform relaxation measurement. Recommendation 8: BWP handover delay requirements based on DCI in RAN4 are not affected by cross-slot scheduling.
