Description

Relaxation measurement method and communication device

Cross Reference to Related Applications

The present application claims priority from chinese patent office, application number 202010241083.9, application name "a method of measuring relaxation adjustment requirements, UE and network device" filed 31 in 03/2020, the entire contents of which are incorporated herein by reference.

Technical Field

The present application relates to the field of communications technologies, and in particular, to a relaxation measurement method and a communication device.

Background

Due to mobility of the terminal, the terminal may move from coverage of one cell to coverage of another cell, and in order to ensure service continuity and communication quality of the terminal, the terminal may perform cell reselection (reselection) or cell handover (handover). Both cell reselection and cell handover require the terminal to make cell measurements, i.e. radio resource management (radio resource management, RRM) measurements. Wherein, the terminal device performs RRM measurement and cell reselection procedures while the terminal device is in a radio resource control (radio resource control, RRC) idle state (abbreviated as rrc_idle state) and an RRC deactivated state (abbreviated as rrc_inactive state).

The terminal in the rrc_idle state and the rrc_inactive state periodically performs RRM measurement. In some scenarios, however, it is not necessary to make RRM measurements frequently, e.g. when the terminal is stationary or the speed of movement of the terminal is low. Thus, in order to reduce the power consumption of the terminal, the concept of RRM relaxation measurement (RRM measurement relax) is currently proposed, i.e. in case certain measurement scenarios are fulfilled, the terminal may perform RRM relaxation measurement, e.g. the terminal may decrease the number of RRM measurements (e.g. increase the measurement interval of RRM measurements). And different measurement scenarios, the strategy for performing RRM relaxation measurements is also different. For example, the terminal is not at the cell edge, the terminal may not perform RRM measurements on the neighbor cells; for another example, the terminal moves at a low speed, and the terminal may perform RRM measurements at longer measurement intervals.

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

Disclosure of Invention

The application provides a relaxation measurement method and a communication device, which are used for determining a relaxation measurement strategy to be adopted by a terminal after different measurement scenes are switched, so as to consider the energy consumption requirement and the communication performance requirement of the terminal.

In a first aspect, embodiments of the present application provide a relaxation measurement method that may be performed by a first communication device, which may be a terminal or a communication device capable of supporting the functions required by the terminal to implement the method, such as a chip system. The following describes an example in which the first communication apparatus is a terminal. The method comprises the following steps:

the terminal switches from the first relaxation measurement scenario to the second relaxation measurement scenario, after which the terminal performs relaxation measurements using a target relaxation measurement strategy, wherein one relaxation measurement scenario corresponds to one relaxation measurement strategy, and the target relaxation measurement strategy comprises a relaxation measurement strategy corresponding to the second relaxation measurement scenario. In the scheme, under the condition that the terminal switches the relaxation measurement scene, the relaxation measurement strategy adopted by the relaxation measurement after the terminal is determined.

In a first possible implementation, the first relaxation measurement scenario corresponds to a first relaxation measurement strategy and the second relaxation measurement scenario corresponds to a second relaxation measurement strategy, and the target relaxation measurement strategy comprises switching from the first relaxation measurement strategy to the second relaxation measurement strategy. In the scheme, the terminal is switched from the first relaxation measurement strategy to the second relaxation measurement strategy directly, namely, is switched to the relaxation measurement strategy corresponding to the second relaxation measurement scene directly, so that the scheme is simpler.

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 is switched from the first relaxation measurement scene to the second relaxation measurement scene, and the terminal is directly switched from the first relaxation measurement strategy to the second relaxation measurement strategy. The terminal is directly switched from the high-energy consumption measurement strategy to the low-energy consumption measurement strategy after being switched from the high-energy consumption measurement scene to the low-energy consumption measurement scene, so that the energy consumption of the terminal is maximally saved.

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 is switched from the first relaxation measurement scene to the second relaxation measurement scene, and the terminal is directly switched from the first relaxation measurement strategy to the second relaxation measurement strategy. The terminal is directly switched from the low-energy consumption measurement strategy to the high-energy consumption measurement strategy after being switched from the low-energy consumption measurement scene to the high-energy consumption measurement scene, so that the communication performance of the terminal is ensured to the maximum.

In a second possible implementation, the first relaxation measurement scenario corresponds to a first relaxation measurement strategy, the second relaxation measurement scenario corresponds to a second relaxation measurement strategy, and the target relaxation measurement strategy comprises executing a third relaxation measurement strategy within a first preset time period, and executing the second relaxation measurement strategy after the first preset time period. In the scheme, after the terminal switches the measurement scene, a relaxation measurement scene is executed first, and then a second relaxation measurement strategy is executed, namely the terminal is switched to the second relaxation measurement strategy in a transitional manner, so that the energy consumption of the terminal is saved as much as possible, and meanwhile, the communication performance of the terminal is ensured.

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 is switched from the first relaxation measurement scene to the second relaxation measurement scene, one relaxation measurement scene is executed first, and then the second relaxation measurement strategy is executed. The terminal is switched from the low-energy consumption measurement scene to the high-energy consumption measurement scene, and then is switched from the low-energy consumption measurement strategy to the high-energy consumption measurement strategy, so that the communication performance of the terminal is ensured, and the energy consumption of the terminal is saved 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 is switched from the first relaxation measurement scene to the second relaxation measurement scene, one relaxation measurement scene is executed first, and then the second relaxation measurement strategy is executed. The terminal is switched from the high-energy consumption measurement scene to the low-energy consumption measurement scene, and then is switched from the high-energy consumption measurement strategy to the low-energy consumption measurement strategy, so that the communication performance of the terminal is ensured as much as possible while the energy consumption of the terminal is saved.

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

For example, the third relaxation measurement policy may comprise the first relaxation measurement policy. I.e. the terminal first performs the first relaxed measurement strategy previously adopted, avoiding frequent switching between different measurement strategies.

Still further exemplary, the third relaxation measurement strategy may comprise performing a relaxation measurement according to a preset at least one measurement parameter, wherein the at least one measurement parameter comprises one or more of the following parameters: measuring interval, number of adjacent cells to be measured, and number of frequency points to be measured of adjacent cells to be measured. The third relaxation measurement strategy can execute relaxation measurement according to preset measurement parameters, the value of the measurement parameters can be preset, and the relaxation measurement strategy is different from the first relaxation measurement strategy or the second relaxation measurement strategy, is flexible, and is more beneficial to considering the energy saving requirement of the terminal and the communication performance requirement of the terminal.

Wherein the performing of the relaxation measurement according to the preset at least one measurement parameter may comprise:

in a first aspect, the relaxation measurement is performed according to a first value of a first measurement parameter, the first measurement parameter being any one of the at least one measurement parameter. I.e. performing a relaxation measurement according to a fixed value of the measurement parameter, the complexity is reduced.

And according to a second scheme, performing relaxation measurement according to a 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 a preset initial value of the first measurement parameter.

Illustratively, the preset rule includes sequentially decrementing the first values according to an adjustment factor; or, the preset rule includes sequentially increasing the first values according to the adjustment factors. The measurement parameters are variable in value within the preset duration, and the measurement mode is executed according to the variable value, so that the energy saving requirement of the terminal and the communication performance requirement of the terminal are both facilitated.

In a possible implementation, 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 relaxed measurement scenario indicates that the terminal is not at a cell edge and the movement speed of the terminal is below a preset threshold, and the second relaxed measurement scenario indicates that the terminal is not at a cell edge or the movement speed of the terminal is below a preset threshold.

In this case, the first relaxation measurement strategy comprises performing a relaxation measurement according to a third value of the first measurement parameter, and the second relaxation measurement strategy comprises performing a relaxation measurement according to a fourth value of the first measurement parameter, wherein the first value is larger than the second value, the first value is larger than the fourth value, and the second value is larger than or equal to the fourth value. According to the scheme, after the terminal is switched from the low-energy consumption measurement scene to the high-energy consumption measurement scene, the terminal can sequentially reduce the values of the measurement parameters in a period of time to obtain the second value, and perform relaxation measurement according to the second value, and the communication performance of the terminal can be gradually improved as the second value is larger than or equal to the fourth value.

In a possible implementation, 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 relaxed measurement scenario indicates that the terminal is not at a cell edge or that the speed of movement of the terminal is below a preset threshold, the second relaxed measurement scenario indicates that the terminal is not at a cell edge and that the speed of movement of the terminal is below a preset threshold.

In this case, the first relaxation measurement strategy comprises performing a relaxation measurement according to a third value of the first measurement parameter, and the second relaxation measurement strategy comprises performing a relaxation measurement according to a fourth value of the first measurement parameter, wherein the first 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 smaller than the second value, the first value is smaller than the third value, and the second value is smaller than or equal to the third value. According to the scheme, after the terminal is switched from a high-energy consumption measurement scene to a low-energy consumption measurement scene, the terminal can sequentially increase the values of the measurement parameters in a period of time to obtain a second value, and perform relaxation measurement according to the second value, and as the second value is larger than or equal to the third value, the communication performance of the terminal can be gradually reduced, and then the energy saving effect of the terminal is improved. Or after the terminal is switched from the high-energy consumption measurement scene to the low-energy consumption measurement scene, the terminal can sequentially reduce the values of the measurement parameters in a period of time to obtain a second value, and perform relaxation measurement according to the second value, and as the second value is smaller 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 is reduced.

In a possible implementation, the relaxation measurements include RRM relaxation measurements or radio link monitoring (radio link monitoring, RLM) relaxation measurements.

In a possible implementation manner, the method further includes: the terminal receives indication information from the network device, the indication information being used to indicate a target relaxation measurement strategy. The terminal determines a target relaxation measurement policy based on an indication of the network device.

The network device may directly indicate the target relaxation measurement policy through the indication information, or may indirectly indicate the target relaxation measurement policy, which is exemplary:

the direct indication mode I, the indication information comprises measurement parameters, and the measurement parameters comprise one or more of the following parameters: measuring the interval, the number of the cells to be measured and the number of the frequency points to be measured of the cells to be measured. According to the scheme, the network equipment directly instructs the terminal to carry out relaxation measurement according to the measurement parameters, and the method is simple and direct.

The direct indication mode II and the indication information are used for indicating a plurality of relaxation measurement strategies, and the target relaxation measurement strategy is one or more of the relaxation measurement strategies. The network device can directly instruct the predefined various relaxation measurement strategies, and the signaling overhead can be reduced.

Further, the indication information is further used for indicating the terminal to execute the target relaxation measurement strategy in case of switching from the first relaxation measurement scene to the second relaxation measurement scene. In this scheme, the time for which the network device transmits the indication information is not limited, for example, the network device may transmit the indication information before the terminal switches from the first relaxation measurement scenario to the second relaxation measurement scenario.

The indirect indication mode comprises indication information, wherein the indication information comprises a switching criterion according to which the terminal switches the relaxation measurement strategy, the switching criterion corresponds to the target relaxation measurement strategy, the switching criterion comprises a first criterion or a second criterion, the first criterion indicates that the energy consumption of the terminal is preferentially saved, and the second criterion indicates that the communication quality is preferentially ensured. The scheme indirectly indicates the target relaxation measurement strategy through the switching criteria.

Illustratively, the indication information includes m-bit information, m being greater than or equal to 1; alternatively, the indication information includes a priority of the terminal service. Namely, the switching criterion is indicated by m-bit information or the switching criterion is indicated by the priority of terminal service, so that the method is flexible.

In a possible implementation manner, the terminal can determine the target relaxation measurement strategy according to the switching criterion, so that the actual requirement of the terminal is met. For example, a relaxed measurement strategy corresponding to a first criterion may be selected, or a relaxed measurement strategy corresponding to a second criterion may be selected, such as to prioritize energy saving requirements, or to prioritize communication quality.

In a second aspect, embodiments of the present application provide a relaxation measurement method that may be performed by a second communication device, which may be a network appliance or a communication device, such as a chip system, capable of supporting the functionality required by the network appliance to implement the method. The following describes an example in which the second communication apparatus is a network device. The method comprises the following steps:

the network device determines indication information and transmits the indication information to the terminal, wherein the indication information is used for indicating the terminal to execute a target relaxation measurement strategy to be used by relaxation measurement after switching from a first relaxation measurement scene to a second relaxation measurement scene. According to the scheme, aiming at the condition that the terminal is switched from a first relaxation measurement scene to a second relaxation measurement scene, a target relaxation measurement strategy is indicated for the terminal, so that the terminal definitely uses the relaxation measurement strategy to execute relaxation measurement.

The terminal device may communicate with the core network via a radio access network (radio access network, RAN), exchanging voice and/or data with the RAN. The terminal apparatus may include a User Equipment (UE), a wireless terminal apparatus, a mobile terminal apparatus, a device-to-device (D2D) terminal apparatus, a V2X terminal apparatus, a machine-to-machine/machine-type communications, an M2M/MTC terminal apparatus, an internet of things (internet of things, ioT) terminal apparatus, a subscriber unit (subscriber unit), a subscriber station (subscriber station), a mobile station (mobile station), a remote station (remote station), an Access Point (AP), a remote terminal (access terminal), a user terminal (user agent), an aircraft (e.g., a drone, a hot air balloon, a civil aircraft, etc.), or a user equipment (user device), etc. For example, mobile telephones (or "cellular" telephones) computers with mobile terminal devices, portable, pocket, hand-held, computer-built mobile devices, and the like may be included. Such as personal communication services (personal communication service, PCS) phones, cordless phones, session initiation protocol (session initiation protocol, SIP) phones, wireless local loop (wireless local loop, WLL) stations, personal digital assistants (personal digital assistant, PDAs), and the like.

The wearable device can also be called as a wearable intelligent device or an intelligent wearable device, and is a generic name for intelligently designing daily wear and developing wearable devices, such as glasses, gloves, watches, clothes, shoes, and the like, by applying wearable technology.

Namely, the NR system supports RRC to support three states, namely a connected RRC_connected state, an RRC_inactive state and an RRC_idle state. The transition between these three states is shown in fig. 2, where the UE is in rrc_idle to establish an RRC connection, transitions to rrc_connected state, and rolls back to rrc_idle state by releasing the RRC connection. When the UE in the rrc_connected state is in the low-demand state, the RRC connection may be delayed to be released to the rrc_inactive state, and the UE may be retracted to the rrc_idle state by releasing the RRC connection. The terminal may be in an rrc_idle state or an rrc_inactive state or an rrc_connected state depending on the RRC state between the terminal and the network device.

As shown in fig. 3, which is a schematic diagram of movement of a terminal in cell 1, cell 2 and cell 3, the terminal may move from the coverage of one cell to the coverage of another cell due to mobility of the terminal. In order to ensure service continuity and communication quality of the terminal, the terminal is required to perform cell reselection (reselection) or cell handover (handover). The terminal obtains continuous service of the wireless network through reselection and handover among cells with different coverage areas. The cell reselection and the cell switching both require the terminal to perform RRM measurement, and the terminal determines whether the cell is within a certain coverage area through RRM measurement, receives reference signals sent by a plurality of network devices, and completes the cell reselection or the cell switching according to the power of the reference signals.

The cell reselection is mainly realized by the terminal, and the terminal completes the cell reselection after meeting certain triggering conditions and access criteria. And the cell handover requires the network device to configure RRM measurement parameters for the terminal and configure the terminal according to the feedback of the terminal. And the terminal triggers the reporting of the measurement event when the RRM measurement result meets a certain condition. After receiving the report from the terminal, the network device may send a handover command to the terminal, indicating that the terminal will be handed over from one cell to another cell.

The purpose of RRM measurement is to realize management allocation of resources, and the types of RRM measurement include co-frequency measurement and inter-frequency/inter-system measurement. The same-frequency measurement comprises measuring other frequency points of the current service cell in the same frequency band and adjacent cell frequency points which are the same as the central frequency point of the frequency band supported by the service cell; different frequency measurement is to measure adjacent cell frequency points which are different from the central frequency band of the frequency band supported by the serving cell; and measuring different systems, namely measuring adjacent cell frequency points which are not in the same system with the serving cell. When the terminal is in the rrc_idle state or the rrc_active state, there is no RRC connection between the terminal and the network device. When the signal quality of the cell (also referred to herein as a serving cell) where the terminal resides is lower than a certain threshold, the terminal measures the signal quality of the serving cell and the neighboring cells of the cell (also referred to herein as neighboring cells) adjacent to the serving cell according to the common-frequency, different-frequency and/or different-system neighboring cell information configured in the system message by the network device, and determines whether the signal quality of the neighboring cells meets the cell reselection condition. If the signal quality of the neighbor cell meets the cell reselection condition, the terminal resides in the neighbor cell. When the terminal is in the RRC_connected state, RRC connection exists between the terminal and the network equipment, and the network equipment configures the terminal to perform same-frequency, different-frequency and/or different-system neighbor cell measurement through RRC signaling. And the terminal reports the signal quality measurement results of the service cell and the neighbor cell to the network equipment through the RRC signaling, and the network equipment switches the terminal to the cell with better signal quality according to the measurement result when the terminal is in the cell. Therefore, whether the cell reselection is in the RRC_idle state and the RRC_inactive state or the cell handover is in the RRC_connected state, the cell reselection is based on the signal quality measurement result of the terminal to the serving cell and the neighbor cell.

For measurement of different frequencies and/or different system neighbor cells in a connection state, according to the capability of the terminal, the terminal can adopt a measurement mode requiring gap (gap) measurement, and can also adopt a measurement mode not requiring gap measurement to measure the different frequencies and/or the different system neighbor cells. If the terminal has a plurality of radio frequency paths and can support to simultaneously receive signals on different frequencies or different system neighbor cells when receiving and transmitting signals on a service cell, the terminal supports a measurement mode without the need of gap measurement to measure the signals of the different frequencies or the different system neighbor cells; otherwise, the terminal adopts a measurement mode requiring gap measurement to measure signals of different frequencies or different system neighbor cells. And stopping signal receiving and transmitting on the serving cell in the gap by the terminal, adjusting the radio frequency channel to an inter-frequency or inter-system frequency point, and receiving signals of an inter-frequency or inter-system neighbor cell. The network device semi-statically configures the gap through RRC signaling.

Referring to fig. 4, a configuration of the gap is shown, and is mainly composed of 3 parameters, wherein the 3 parameters are respectively measured time slot repetition periods (measurement gap repetition period, MGRP) for configuring the gap period; measuring a slot length (measurement gap length, MGL) for configuring the length of the gap; an offset (gapOffset) is measured for configuring the start position of the gap. From these 3 parameters, it can be determined that the gap starts on the system frame number (system frame number, SFN) and subframe (subframe) satisfying the following conditions:

SFN mod T＝FLOOR(gapOffset/10)；

subframe＝gapOffset mod 10；

T＝MGRP/10；

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

For inter-frequency and/or inter-system neighbor cell measurements in the rrc_idle state and the rrc_inactive state, since the terminal does not need to transmit and receive data on the serving cell of the terminal, it may not need to configure a measurement window.

The measurement of NR neighbors may be based on synchronization signal blocks (Synchronization Signal Block, SSB), but due to the specificity of SSB signal design, if a measurement mode requiring measurement of the gap is used to perform a connection state different frequency or different system neighbor measurement), the network device needs to configure an accurate gap location to include the SSB of the neighbor.

Accurate gap position is needed to be measured, the time domain position of the gap is needed to be measured, the timing of the PCell is referred, the time domain position of the neighbor SSB is sent according to the neighbor timing, and in order to configure the accurate gap position, the network equipment needs to know the timing deviation between the PCell and the NR neighbor, so that the SFN and the subframe number of the SSB of the NR neighbor correspond to the SFN and the subframe number of the PCell. The timing offset between the PCell and the NR neighbor cell may be obtained by a system frame number and frame timing offset (SFN and frame timing difference, SFTD) measurement of the terminal. The SFTD measurements include deviations of the SFN and timing deviations of the frame boundaries.

Current protocols support (EUTRA-NR Dual Connectivity ), also called SFTD measurement between LTE PCell and NR PSCell under EN-DC, support (NR-EUTRA Dual Connectivity ), also called SFTD measurement between NR PCell and LTE PSCell under NE-DC, support (NR Dual Connectivity ), also called SFTD measurement between NR PCell and NR PSCell under NR-DC, and support SFTD measurement between LTE PCell and NR neighbor under non-DC (Dual Connectivity ).

During SFTD measurement, the terminal needs to receive signals of another measured cell outside the PCell to acquire timing information of the cell. In DC, since the terminal can support simultaneous operation on the PCell and the PSCell, knowing timing information of the PCell and the PSCell at any moment, SFTD measurement is not difficult. And SFTD measurement between LTE PCell and NR neighbor cells under DC is not performed, if the radio frequency path of the terminal does not support receiving and transmitting signals on PCell while receiving signals on NR neighbor cells, SFTD measurement has a certain difficulty. To this end, the current protocol supports the following two modes: SFTD measurements of gap and SFTD measurements of connected discontinuous reception (connected discontinuous reception, CDRX) inactive periods are required.

In general, a terminal detects synchronization signals of other cells in a measurement gap (measurement gap), synchronizes with the synchronization signals of other cells according to the synchronization signals of other cells, and performs related measurement on reference signals sent by other cells, thereby completing measurement of other cells. However, interrupting the reception and transmission of the original service area data in the measurement gap has a large influence on throughput. Some terminals can support CA combination of many different frequency bands, have multiple receiving paths, and have the capability of directly measuring different frequencies/different systems without configuring gap. Therefore, the data transmission of the original service area is not interrupted, and the service of the original service area of the terminal is not influenced. However, if the number of supported frequency bands and CA combinations is large, the frequency bands of different frequencies/different systems to be measured are also large, and based on cost consideration, the terminal usually can only support a limited number of frequency band combinations, but cannot support the measurement of the gap measurement different frequency/different systems under all frequency band combinations.

For example, in the LTE system, which measurement band combinations need to measure the gap and which measurement band combinations do not need to measure the gap may be reported in the capability message by the cell "interffreqneedledforgap"/"inter rat-needledforgap". Wherein the band (band) of the service area is indicated by a single band supporting cell "band listueutra" or by a CA supporting cell "band coding listueutra"; the target measurement alien band is indicated by a cell "inter freqbandlist", and the target measurement alien band is indicated by a cell "inter rat-BandList". The service area band/CA combination is indicated by 1 bit, and whether the measurement of the gap is needed for the inter-frequency band or the inter-frequency band is measured, for example, a value of 1 (True) for 1 bit indicates that the gap measurement is needed, and a value of 0 (False) for 1 bit indicates that the gap measurement is not needed.

Illustratively, as shown in table 1, which is an illustration of measurement capability reported by a terminal, the network device may determine whether to configure a gap during measurement according to table 1.

TABLE 1 schematic representation of measurement capability information

The network device may determine whether to configure the measured 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 a main source of power consumption of the terminal. However, in some measurement scenarios, such as when the terminal is stationary or the movement speed of the terminal is low, it is not necessary to perform RRM measurements frequently. So in order to reduce the power consumption of the terminal, the concept of RRM relaxation measurement is currently proposed. The terminal may reduce the number of RRM measurements (e.g., increase the period of RRM measurements) while performing RRM relaxation measurements, and for example, the terminal may reduce the measurement object (e.g., the terminal reduces the number of target frequency points to be measured or the terminal reduces the number of neighbor cells to be measured).

In some embodiments, it is proposed that the terminal may perform RRM relaxation measurements in case certain measurement scenarios are fulfilled. For example, the terminal is not at the cell edge, the terminal may not perform RRM measurements on the neighbor cells; for another example, the terminal moves at a low speed, and the terminal may perform RRM measurements at longer measurement intervals. The strategy for performing RRM relaxation measurements is also different for different measurement scenarios. But due to the mobility of the terminal, the terminal may switch from one measurement scenario to another, e.g. the terminal may move from the cell center to the cell edge, e.g. the movement speed of the terminal becomes fast, etc. This involves a strategy for terminal demand handover RRM relaxation measurement, but there is no further solution for how the terminal performs RRM relaxation measurement after the terminal switches between different measurement scenarios.

It should be noted that, in the radio link monitoring (radio link monitoring, RLM) relaxation measurement, a terminal handover monitoring scenario is also involved, and after the handover monitoring scenario is also present, how the terminal performs the RLM relaxation measurement has no further scheme.

In view of this, the embodiment of the present application provides a relaxation measurement method, which is specific to a policy of relaxation measurement (hereinafter, also referred to as relaxation measurement policy) to be adopted by a terminal after a measurement scenario is switched by the terminal, so as to consider both a power consumption requirement and a communication performance requirement of the terminal.

The technical scheme provided by the embodiment of the application can be used for a wireless communication system, such as a 4.5G system or a 5G system, a further evolution system based on LTE or NR, a future wireless communication system or other similar communication systems and the like. Moreover, the technical scheme provided by the embodiment of the application can be used for RRM measurement and also can 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 embodiments of the present application may also be referred to as RRM relaxation measurement mode; when the technical scheme is used for RLM measurement, the relaxation measurement method provided by the embodiment of the application may also be referred to as an RLM relaxation measurement method. Without conflict, RRM in the embodiments of the present application may be replaced by RLM. The technical scheme is applied to RRM measurement as an example, and the technical scheme provided by the embodiment of the application is described below with reference to the accompanying drawings.

In the following description, the application of the method to the network architecture shown in fig. 1 is taken as an example. In addition, the method may be performed by two communication devices, such as a first communication apparatus and a second communication apparatus. The first communication device may be a network apparatus or a communication device (e.g., a chip system) capable of supporting a function required by the network apparatus to implement the method, and the first communication device may be a terminal or a communication device (e.g., a chip system) capable of supporting a function required by the terminal to implement the method. The same is true for the second communication device, which may be a network appliance or a communication device (e.g. a chip system) capable of supporting the functions required by the network appliance to implement the method, or the second communication device may be a terminal or a communication device (e.g. a chip system) capable of supporting the functions required by the terminal to implement the method. And there is no limitation on the implementation manner 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, the second communication device is a communication device capable of supporting the functions required for the terminal to implement the method, and so on. Wherein the network device is, for example, a base station.

Referring to fig. 5, a flowchart of an RRM measurement method according to an embodiment of the present application is shown in the following description, and the method is implemented by a network device and a terminal, that is, a first communication apparatus is a terminal, and a second communication apparatus is a network device. It should be noted that the embodiments of the present application are merely examples of implementation through a network device and a terminal, and are not limited to these two communication apparatuses.

S501, the terminal switches from a first RRM relaxation measurement scene to a second RRM relaxation measurement scene.

S502, the terminal executes a target RRM relaxation measurement strategy, wherein the target RRM relaxation measurement strategy comprises an RRM relaxation measurement strategy corresponding to the second RRM relaxation measurement scene.

RRM relaxation measurement may be understood as that when the terminal performs RRM relaxation measurement, the terminal may reduce the measurement object (e.g. reduce the number of measurement target frequency points, reduce the number of neighbor cells to be measured); alternatively, the terminal may reduce the number of RRM measurements (e.g., extend the measurement interval); or, the terminal reduces the measuring objects and the times of RRM measurement 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 measurements, in other words, when the terminal satisfies a certain one of the measurement scenarios, the terminal may perform RRM relaxation measurements. Several possible RRM relaxation measurement scenarios are listed below.

And in the first measurement scene, the signal quality change of the serving cell of the terminal does not exceed a set threshold 1 within a set duration, namely the terminal is stationary or moves at a low speed. In this scenario, the signal quality of the serving cell and the neighbor cell are relatively stable, and the signal quality is kept within a certain range for a long time, so that the terminal can perform RRM relaxation measurement on the serving cell and also can perform RRM relaxation measurement on the neighbor cell.

And the signal quality of the second measurement scene and the serving cell is higher than a set threshold 2, namely the terminal equipment is not at the edge of the cell. In this scenario, the signal quality of the serving cell is higher, so that a stable and better service can be provided for the terminal, and therefore, the terminal does not need to reselect to the neighboring cell, and RRM relaxation measurement can be performed on the neighboring cell.

The signal quality of the serving cell is higher than a set threshold 2 in the measurement scene III, and the signal quality change of the serving cell does not exceed the set threshold 1, namely the terminal is not at the cell edge and the terminal is stationary or moves at a low speed. In the scene, the signal quality of the service cell is higher, stable and better service can be provided for the terminal, the signal quality of the service cell and the signal quality of the neighbor cell are both stable, the service cell and the neighbor cell are kept in a certain range for a long time, the terminal can perform RRM relaxation measurement on the service cell, and RRM measurement on the neighbor cell is not performed.

Although the RRM relaxation measurement method in the first and second scenario can ensure the cell coverage of the terminal. However, due to mobility of the terminal, when the terminal may switch from one measurement scenario to another, there may be a certain cell switching risk if the measurement method is relaxed according to the RRM corresponding to the switched measurement scenario. For example, when the terminal is switched from the second scenario to the first scenario, that is, the terminal moves at a low speed and is far away from the cell edge (that is, is not at the cell edge), if the terminal performs RRM relaxation measurement on the neighboring cell according to the RRM relaxation measurement method of the second scenario, this may cause that the terminal device cannot reselect to the neighboring cell for a long time, and eventually affects the communication performance of the terminal.

In view of this, the embodiment of the present application can determine the RRM relaxation measurement policy that needs to be adopted by the terminal 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 policy, so that the energy consumption requirement and the communication performance requirement of the terminal can be both considered.

There are a variety of RRM relaxation measurement scenarios, such as the three measurement scenarios described above. There are also a variety of RRM relaxation measurement strategies, such as performing RRM relaxation measurements at a first measurement interval, and not performing RRM measurements on the neighbor, for example. The RRM relaxation measurement strategies corresponding to different RRM relaxation measurement scenarios are also different. Illustratively, one RRM relaxation measurement scenario corresponds to one RRM relaxation measurement strategy, as shown in table 2 below.

TABLE 2

In table 2, policy 1 and policy 2 may be the same, e.g., 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, e.g. the first measurement interval and the second measurement interval are different; alternatively, the first measurement interval and the second measurement interval are the same, but the number of neighbor cells measured by policy 1 is different from the number of neighbor cells measured by policy 2; or the first measurement interval is the same as the second measurement interval, the number of the adjacent cells measured by the strategy 1 is the same as the number of the adjacent cells measured by the strategy 2, but the number of the frequency points of the adjacent cells measured by the strategy 1 is different from the number of the frequency points of the adjacent cells measured by the strategy 2. It should be noted that, table 2 illustrates only policies 1-3 at measurement intervals, and in some embodiments, policies 1-3 may be policies that measure multiple neighbor cells to perform RRM relaxation measurement, respectively. For example, strategy 1 performs a RRM relaxation measurement strategy for measuring L neighbors; strategy 2 is a strategy for measuring P neighbor cells to execute RRM relaxation measurement; policy 1 performs RRM relaxation measurements for the measurement Q neighbors, where L, P and Q are both positive integers and L, P and Q may be different. In other embodiments, policies 1-3 may be policies that measure multiple frequency points of each neighbor to perform RRM relaxation measurements, respectively. For example, strategy 1 performs RRM relaxation measurement for L frequency points measuring a certain neighbor cell; strategy 2 is a strategy for measuring P frequency points of a certain neighbor cell and executing RRM relaxation measurement; strategy 1 performs RRM relaxation measurements for Q bins measuring a certain neighbor, where L, P and Q are positive integers and L, P and Q may be different. It should be appreciated that herein, RRM relaxation measurements are performed as examples of measuring neighbor cells, but are not limited to performing RRM relaxation measurements on a serving cell, or performing RRM relaxation measurements on a serving cell and neighbor cells.

It should be understood that in table 2, the terminal performs RRM measurement using policy 3 with the lowest energy consumption in measurement scenario three. That is, the measurement scenario three phases are low-energy measurement scenarios compared to measurement scenario one or measurement scenario two. I.e. the energy consumption consumed by the terminal to perform RRM measurements with policy 3 is lower than the energy consumption consumed by the terminal to perform RRM measurements with either policy 1 or policy 2. The first measurement scenario may be a low-energy measurement scenario or a high-energy measurement scenario, as compared to the second measurement scenario. That is, the energy consumption of the terminal for performing the RRM measurement using the policy 1 may be greater than or equal to the energy consumption of the terminal for performing the RRM measurement using the policy 2, or may be less than the energy consumption of the terminal for performing the RRM measurement using the policy 2.

It should be understood that, when the terminal performs RRM measurement in the first measurement scenario (or when the terminal adopts the policy 2 in the second measurement scenario), the communication performance of the terminal can be ensured more than when the terminal adopts the policy 3 in the third measurement scenario. In other words, the communication performance of the third measurement scenario is the lowest, and the communication performance of the first measurement scenario may be higher than the communication performance of the second measurement scenario, or may be lower than the communication performance of the second measurement scenario.

In addition, it should be noted that, table 2 only exemplifies that there are three RRM relaxation measurement scenarios, and each RRM relaxation measurement scenario corresponds to one RRM relaxation measurement policy. The embodiments of the present application do not limit the number of RRM relaxation measurement scenarios and the number of RRM relaxation measurement strategies. In the following description, the RRM relaxation measurement scenario and the RRM relaxation measurement policy are taken as an example, that is, RRM relaxation measurement scenario M corresponds to RRM relaxation measurement policy M, RRM relaxation measurement scenario N corresponds to RRM relaxation measurement policy N, M and N are different.

It should be appreciated that when the terminal switches from one RRM relaxation measurement scenario to another, 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 may perform the target RRM relaxation measurement policy.

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

TABLE 3 Table 3

Note that, in table 3, RRM relaxation measurement policy M is a policy corresponding to RRM relaxation measurement scene M in table 1, and RRM relaxation measurement policy N is a policy corresponding to RRM relaxation measurement scene N in table 2. Table 3 only lists 4 possible RRM relaxation measurement strategies corresponding to RRM relaxation measurement scenario N (i.e., the switched RRM relaxation measurement scenario) after the terminal switches from RRM relaxation measurement scenario M to RRM relaxation measurement scenario N. However, the types and the number of RRM relaxation measurement strategies corresponding to the switched RRM relaxation measurement scenario 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 RRM relaxation measurement at normal measurement intervals within a preset duration, perform RRM relaxation measurement policy N after the preset duration, and so on. It should be understood that here the normal measurement interval is that the RRM relaxation measurement corresponds to a measurement interval that is relatively smaller than the RRM relaxation measurement.

In order to facilitate understanding, a specific adjustment method of the RRM relaxation measurement strategy is described below in conjunction with different situations of a specific handover scenario of a terminal. In the following description, the terminal is taken as an example to switch from the RRM relaxation measurement scenario M to the RRM relaxation measurement scenario N.

In a possible implementation one, the terminal switches from RRM relaxation measurement scenario M to RRM relaxation measurement scenario N, and the terminal may directly switch from RRM relaxation measurement policy M to RRM relaxation measurement policy N, performing RRM relaxation measurement. That is, the target RRM relaxes the measurement policy N to the measurement policy N corresponding to the measurement scenario N after handover. The following describes several possible target RRM relaxation measurement strategies in different situations of measurement scene switching.

In a first example, RRM relaxation measurement scenario M is measurement scenario one, RRM relaxation measurement scenario N is measurement scenario three, and the target RRM relaxation measurement policy may be policy 3. That is, the terminal switches from a high-energy consumption measurement scenario to a low-energy consumption measurement scenario, and the terminal may directly execute the low-energy consumption policy. In other words, the terminal switches from a high energy consumption measurement scenario to a low energy consumption measurement scenario, and the terminal switches from a measurement strategy corresponding to the high energy consumption measurement scenario (which may also be referred to herein as a high energy consumption measurement strategy) to a measurement strategy corresponding to the low energy consumption measurement scenario (which may also be referred to herein as a low energy consumption measurement strategy). The scheme can reduce the frequency of RRM measurement and maximally save the power consumption of the terminal.

When the terminal switches from measurement scenario one to measurement scenario three, i.e. the terminal may initially be at the cell edge, but may be far away from the cell edge due to the low speed of the terminal, i.e. the terminal is not at the cell edge and the terminal moves at low speed. In this case, the terminal may directly execute policy 3. Since policy 3 is to not perform RRM measurement of the neighbor cell, power consumption of the terminal can be maximally saved.

In a second example, RRM relaxation measurement scenario M is measurement scenario three described above, RRM relaxation measurement scenario N is measurement scenario one described above, and the target RRM relaxation measurement policy may be policy 1 described above. That is, the terminal may switch from a low energy consumption measurement scenario to a high energy consumption measurement scenario, and the terminal may switch directly from a low energy consumption measurement strategy to a high energy consumption measurement strategy. The scheme can maximally ensure the communication performance of the terminal.

When the terminal is switched from measurement scenario one to measurement scenario three, i.e. the terminal is not at the cell edge, and the terminal moves at a low speed, the terminal may be at the cell edge, although the movement speed of the terminal is still low, over a period of time. In this case, the terminal may directly execute policy 1. Namely, RRM measurement is performed on the adjacent cells in time, so that the communication performance of the terminal can be ensured to the maximum.

In a third example, RRM relaxation measurement scenario M is the measurement scenario two described above, RRM relaxation measurement scenario N is the measurement scenario three described above, and the target RRM relaxation measurement policy is policy 3 described above. Similar to the first example, this scheme may also reduce the number of RRM measurements, maximally saving power consumption of the terminal.

The terminal switches from the second measurement scenario to the third measurement scenario, i.e. the terminal is not initially at the cell edge and the movement speed of the terminal is faster, after which the movement speed of the terminal is slower, but the terminal has not yet moved to the cell edge. In this case, the terminal may directly execute policy 3. Since policy 3 is to not perform RRM measurement of the neighbor cell, power consumption of the terminal can be maximally saved.

In a fourth example, RRM relaxation measurement scenario M is measurement scenario three described above, RRM relaxation measurement scenario N is measurement scenario two described above, and the target RRM relaxation measurement policy is policy 2 described above. Similar to the second example, this scheme can also maximally secure the communication performance of the terminal.

When the terminal is switched from measurement scenario three to measurement scenario two, i.e. the terminal is not at the cell edge and the terminal moves at a low speed, the terminal may be at the cell edge, although the movement speed of the terminal is still low, over a period of time. In this case, the terminal may directly execute policy 2. Namely, RRM measurement is performed on the adjacent cells in time, so that the communication performance of the terminal can be ensured to the maximum.

In a fifth example, RRM relaxation measurement scenario M is measurement scenario one described above, and RRM relaxation measurement scenario N is measurement scenario two described above. If policy 1 requires more power consumption by the terminal than policy 2, then the target RRM relaxation measurement policy may be policy 2 to maximally save power consumption by the terminal. If policy 1 is more capable of guaranteeing the communication performance of the terminal than policy 2, the target RRM relaxation measurement policy may be policy 1 to guarantee the communication performance of the terminal at maximum.

In a sixth example, RRM relaxation measurement scenario M is measurement scenario two described above, and RRM relaxation measurement scenario N is measurement scenario one described above. If strategy 2 requires more power consumption by the terminal than strategy 1, then the target RRM relaxes the measurement strategy to strategy 1 described above to maximize power consumption savings. If policy 2 is more capable of guaranteeing the communication performance of the terminal than policy 1, the target RRM relaxation measurement policy may be policy 2 to guarantee the communication performance of the terminal at maximum.

In a second possible implementation, after the terminal switches from the RRM relaxation measurement scenario M to the RRM relaxation measurement scenario N, the terminal performs an RRM relaxation measurement policy for a period of time first, and then performs the RRM relaxation measurement policy N. That is, the target RRM relaxation measurement strategy is to perform one RRM relaxation measurement strategy for a period of time before performing RRM relaxation measurement strategy N. The RRM relaxation measurement strategy, which is performed first over a period of time, may be considered as a transitional relaxation measurement. In other words, the scheme transitions to RRM relaxation measurement strategy N by transitioning the relaxation measurement strategy, compared to the terminal switching directly from RRM relaxation measurement strategy M to RRM relaxation measurement strategy N as described above. The scheme can give consideration to the energy consumption requirement of the terminal and the communication performance requirement of the terminal as much as possible.

The transitional relaxation measurement strategy may be RRM relaxation measurement strategy M or a strategy different from RRM relaxation measurement strategy M. It should be appreciated that the value of the measurement parameter (e.g., measurement interval, etc.) of the transitional relaxation measurement strategy is between the value corresponding to RRM relaxation measurement strategy M and the value corresponding to RRM relaxation measurement strategy N. The terminal is switched from a low energy consumption measurement scene to a high energy consumption measurement scene, and the terminal can be transitionally switched to a high energy consumption measurement strategy. The terminal is switched from a high-energy consumption measurement scene to a low-energy consumption measurement scene, and the terminal can also be switched to a low-energy consumption measurement strategy in a transitional manner. Depending on the RRM relaxation measurement scenario M and the RRM relaxation measurement scenario N, the target RRM relaxation measurement strategy may comprise any of the following strategies:

in a first example, the RRM relaxation measurement scenario M is the measurement scenario three described above, the RRM relaxation measurement scenario N is the measurement scenario one described above, and the target RRM relaxation measurement policy may be to execute the policy 3 within a first preset time period T1, and execute the policy 1 after the first preset time period T1. That is, the transitional relaxation measurement policy is policy 3.

It will be appreciated that when the terminal moves at a low speed towards the cell edge, it may move to the cell edge. In this case, although policy 3 can maximally satisfy the power saving requirement of the terminal as compared with policies 1 and 2. However, in order to ensure the communication performance of the terminal, after the terminal is switched from the measurement scenario three to the measurement scenario one, the terminal may not move to the cell edge in a period of time (for example, the first preset duration T1) because the terminal moves at a low speed, and the terminal executes the policy 3 in the period of time, so that the energy consumption of the terminal can be saved as much as possible. After this time, the terminal may move to the cell edge, at which time the terminal executes policy 1 again, so as 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 may be configured by a network device, and inform the terminal of the value of the first preset duration T1. In some embodiments, the first preset duration T1 may be a value within a range of 10ms-20ms, for example, 10ms,15ms,20ms, etc., and the specific value of the first preset duration T1 is not limited in the embodiments of the present application.

As an alternative to the first example, the target RRM relaxation measurement policy may be to perform RRM measurement in a preset first measurement manner within a first preset time period T1, and then perform policy 1 after the first preset time period T1. That is, the transitional relaxation measurement strategy is the first measurement mode.

The preset first measurement mode can be determined according to the actual requirements of the terminal. In some embodiments, the terminal needs to ensure communication performance preferentially, and the preset first measurement mode may be to not use RRM relaxation measurement (hereinafter referred to as measurement mode 1). For example, the preset first measurement mode may be that RRM measurements are performed on all neighboring cells within the first preset time period T1 according to a preset measurement interval, where the measurement interval may be a measurement interval corresponding to a normal RRM measurement mode, and it should be understood that the normal RRM measurement mode is a RRM relaxation measurement, where RRM measurements before the concept of RRM relaxation measurement occurs may be considered as normal RRM measurements, for example: measurement intervals were not made for measurement relaxation.

In some embodiments, the terminal needs to consider both communication performance and energy consumption, and then the value of a certain measurement parameter corresponding to the preset first measurement mode is larger (hereinafter referred to as measurement mode 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 relaxation measurement strategy. For another example, the number of the neighbor cells to be measured corresponding to the preset first measurement mode is between the number of the neighbor cells to be measured corresponding to the normal RRM measurement mode and the number of the neighbor cells to be measured corresponding to the RRM relaxation measurement strategy, or the number of the frequency points to be measured of the neighbor cells to be measured corresponding to the preset first measurement mode is between the number of the frequency points to be measured corresponding to the normal RRM measurement mode and the number of the frequency points to be measured corresponding to the RRM relaxation measurement strategy.

In other embodiments, the terminal needs to consider both communication performance and energy consumption, and then the values of the multiple measurement parameters (at least two of the measurement interval, the number of measurement neighboring cells, the number of measured frequency points, etc.) of the preset first measurement mode may be located between the parameters corresponding to the measurement policy M and the measurement policy N (hereinafter referred to as measurement mode 3). For example, the measurement interval corresponding to the preset first measurement mode is located between the measurement interval of the RRM measurement policy M and the measurement interval of the RRM measurement policy N, and the number of measurement neighboring cells corresponding to the preset first measurement mode is located between the number of measurement neighboring cells of the RRM measurement policy M and the number of measurement neighboring cells of the RRM measurement policy N. For another example, the measurement interval corresponding to the preset first measurement mode 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 measurement interval of the RRM measurement strategy N by an incremental or decremental mode. The number of the frequency points of the measurement neighbor cell corresponding to the preset first measurement mode can also be located between the number of the frequency points of the measurement neighbor cell of the RRM measurement strategy M and the number of the frequency points of the measurement neighbor cell of the RRM measurement strategy N, so that the number of the frequency points of the RRM measurement strategy M is switched to the number of the frequency points of the RRM measurement strategy N in an increasing or decreasing mode. The type of the measurement parameter of the preset first measurement mode is not limited herein. It should be understood that the value of the measurement parameter of the preset first measurement mode may be an average value of the values of the measurement parameters corresponding to a plurality of measurement strategies (for example, the three measurement strategies in table 2), and RRM measurement is performed in a period of time through the preset first measurement mode, without frequent switching between the RRM measurement strategies, so that increased energy consumption caused by frequent switching can be avoided, and the energy consumption requirement and the communication performance requirement of the terminal can be considered.

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 over a period of time. For example, the initial values of the measurement parameters and the adjustment factors (e.g., increment amplitude, increment number, or decrement amplitude, decrement number) may be preset, so that the terminal may adjust the initial values of the measurement parameters according to the adjustment factors. For example, the preset first measurement manner may be that the terminal sequentially decrements the initial measurement interval according to the decrementing amplitude within the first preset duration T1, and performs RRM measurement according to the decremented measurement interval. It should be understood that the initial measurement interval is greater than the first measurement interval corresponding to the policy 1, and the measurement interval after the initial measurement interval is decremented by the decrementing number within the first preset time period T1 is greater than or equal to the first measurement interval corresponding to the policy 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 intervals for performing the RRM measurement within the first preset duration T1 decrease sequentially, so that the number of measurements within the first preset duration T1 decreases, and the energy consumption of the terminal can be saved as much as possible.

In a second example, the RRM relaxation measurement scenario M is the measurement scenario one described above, the RRM relaxation measurement scenario N is the measurement scenario three described above, and the target RRM relaxation measurement policy may be to execute the policy 1 within a second preset time period T2, and execute the policy 3 after the second preset time period T2. When the terminal moves at a low speed, the terminal may be located at the cell edge for a period of time, after which the terminal is far from the cell edge. In this case, policy 1 may be implemented during this period to ensure the communication performance of the terminal as much as possible. And then executing the strategy 3, so that the energy consumption of the terminal can be saved.

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

As an alternative to the second example, the target RRM relaxation measurement policy may be to perform RRM measurement in a second measurement manner preset for a second preset time period T2, and then perform policy 3 after the second preset time period T2.

The preset second measurement mode may also be determined according to the actual requirement of the terminal, for example, the preset second measurement mode may be the measurement mode 1, the measurement mode 2, the measurement mode 3, etc., and the description of the preset first measurement mode may be referred to specifically, and will not be repeated here.

For example, the measurement interval corresponding to the preset second measurement mode is variable in a period of time, for example, the initial value of the measurement interval may be preset, and the increment amplitude and the increment frequency, or the decrement amplitude and the decrement frequency may be increased.

In some embodiments, the preset measurement mode may be that the terminal sequentially decrements the initial measurement interval by a decrementing amplitude during the second preset duration T2. It should be understood that the initial measurement interval is greater than the first measurement interval corresponding to the policy 1, and the measurement interval after the initial measurement interval has been decremented within the second preset time period T2 is greater than or equal to the first measurement interval corresponding to the policy 1. Since the RRM measurement is still performed within the second preset duration T2, the communication performance of the terminal can be ensured as much as possible, and the measurement intervals for performing the RRM measurement within the second preset duration T2 decrease sequentially, so that the number of measurements within the second preset duration T2 decreases, and the energy consumption of the terminal can be saved as much as possible.

In other embodiments, the preset measurement mode may be that the terminal sequentially increments the initial measurement interval by an increment amplitude to perform RRM relaxation measurement within the second preset time period T2. It should be understood that the initial measurement interval is smaller than the first measurement interval corresponding to the policy 1, and the measurement interval after the initial measurement interval is incremented within the second preset duration T2 is smaller than or equal to the first measurement interval corresponding to the policy 1. Since 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 mode may be the same as or different from the value of the measurement parameter corresponding to the preset first measurement mode.

In a third example, the RRM relaxation measurement scenario M is the measurement scenario three described above, the RRM relaxation measurement scenario N is the measurement scenario two described above, and the target RRM relaxation measurement policy may be to execute the policy 3 described above for a third preset duration T3, and then execute the policy 2 described above after the third preset duration T3.

It should be understood that the moving speed of the terminal may become fast during the movement of the terminal, but a certain time is required for the terminal to move to the cell edge. Therefore, when the terminal is switched from the measurement scene three to the measurement scene two, the terminal can execute the strategy 3 first in a period of time (for example, a third preset period of time T3) and then execute the strategy 2, so that the energy consumption of the terminal can be further saved.

As an alternative to the third example, the target RRM relaxation measurement policy may be to perform RRM measurement in a preset third measurement manner for a second preset time period T2, and perform policy 2 after the second preset time period T2.

Similar to the alternative of the second example, the preset third measurement mode may be determined according to the actual requirements of the terminal. In some embodiments, the preset third measurement mode may be the preset measurement mode 1, the preset measurement mode 2, the preset measurement mode 3, or the like, and specific reference may be made to the foregoing alternative of the second example, which is not repeated herein.

For example, the measurement interval corresponding to the preset third measurement mode is variable in a period of time, for example, the initial value of the measurement interval may be preset, and the increment amplitude and the increment frequency, or the decrement amplitude and the decrement frequency may be increased.

In some embodiments, the preset measurement mode may be that the terminal sequentially decrements the initial measurement interval according to the decrementing amplitude within the third preset duration T3, and performs RRM measurement according to the decremented measurement interval. It should be understood that the initial measurement interval is greater than the second measurement interval corresponding to the policy 2, and the measurement interval after the initial measurement interval is decremented by the decrementing number within the third preset time period T3 is greater than or equal to the second measurement interval corresponding to the policy 2. Since the RRM measurement is still performed within the third preset duration T3, the communication performance of the terminal can be ensured as much as possible, and the measurement intervals for performing the RRM measurement within the third preset duration T3 decrease sequentially, so that the number of measurements within the third preset duration T3 decreases, and 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 mode may be the same as or different from the value of the measurement parameter corresponding to the preset first measurement mode. It should be noted that, similar to the first preset duration T1, the third preset duration T3 may be predefined by a protocol, or may be configured by a network device. The third preset time period T3 may be the same as the first preset time period T1 or may be different from the first preset time period T1.

In a fourth example, the RRM relaxation measurement scenario M is the measurement scenario two described above, the RRM relaxation measurement scenario N is the measurement scenario three described above, and the target RRM relaxation measurement policy may be to execute the policy 2 described above for a fourth preset duration T4, and then execute the policy 3 described above after the fourth preset duration T4.

The terminal switches from the second measurement scenario to the third measurement scenario, i.e. the terminal is not initially at the cell edge and the movement speed of the terminal is faster, after which the movement speed of the terminal is slower, but the terminal has not yet moved to the cell edge. In this case, the terminal may execute policy 2 for a period of time, and then may execute policy 3. Although the terminal is not at the cell edge in this period, in order to avoid that the terminal moves at a higher speed, the terminal may move to the cell edge, and the terminal still executes the policy 2 in this period, so that the communication performance of the terminal can be ensured as much as possible. After this period of time, policy 3 is executed, i.e. RRM measurement of the neighbor cell is not executed, further saving the power consumption of the terminal.

As an alternative to the fourth example, the target RRM relaxation measurement policy may be to perform RRM measurement in a preset fourth measurement manner for a second preset time period T2, and perform policy 3 after the fourth preset time period T4.

Similar to the alternative of the second example, the preset fourth measurement mode may be determined according to the actual requirements of the terminal. In some embodiments, the preset third measurement mode may be the preset measurement mode 1, the preset measurement mode 2, the preset measurement mode 3, or the like, and specific reference may be made to the foregoing alternative of the second example, which is not repeated herein.

For example, the measurement interval corresponding to the preset fourth measurement mode is variable in a period of time, for example, the initial value of the measurement interval may be preset, and the increment amplitude and the increment frequency, or the decrement amplitude and the decrement frequency may be increased. The preset measurement mode may be that the terminal sequentially decrements the initial measurement interval according to the decrementing amplitude within a fourth preset duration T4, and executes RRM measurement according to the decremented measurement interval. It should be understood that the initial measurement interval is greater than the second measurement interval corresponding to the policy 2, and the measurement interval after the initial measurement interval is decremented by the decrementing number within the fourth preset time period T4 is greater than or equal to the second measurement interval corresponding to the policy 2. Since the RRM measurement is still performed within the fourth preset duration T4, the communication performance of the terminal can be ensured as much as possible, and the measurement intervals for performing the RRM measurement within the fourth preset duration T4 decrease sequentially, so that the number of measurements within the fourth preset duration T4 decreases, and the energy consumption of the terminal can be saved as much as possible.

In other embodiments, the preset measurement mode may be that the terminal sequentially increases the initial measurement interval according to the increment amplitude within the fourth preset time period T4, and performs RRM measurement according to the increased measurement interval. It should be understood that the initial measurement interval is smaller than the second measurement interval corresponding to the policy 2, and the measurement interval after the initial measurement interval is incremented after the increment number of times in the fourth preset time period T4 is smaller than or equal to the second measurement interval corresponding to the policy 2. Since RRM measurement is still performed at a smaller measurement interval within the fourth preset duration 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 may be the same as or different from the value of the measurement parameter corresponding to the preset first measurement mode. It should be noted that, similar to the first preset duration T1, the fourth preset duration T4 may be predefined by a protocol, or may be configured by a network device. The fourth preset time period T4 may be the same as the first preset time period T1 or may be different from the first preset time period T1.

In a fifth example, RRM relaxation measurement scenario M is measurement scenario one described above, and RRM relaxation measurement scenario N is measurement scenario two described above. If policy 1 requires more power consumption of the terminal than policy 2, then the target RRM relaxation measurement policy may be policy 2, which maximally saves power consumption of the terminal. If the policy 1 needs to consume less power consumption of the terminal than the policy 2, the target RRM relaxation measurement policy may be to execute the policy 1 in a fifth preset duration T5, and then execute the foregoing policy 2, where the policy 1 is executed in the fifth preset duration T5, so that the power consumption of the terminal may be saved as much as possible; alternatively, the target RRM relaxation measurement strategy may be to perform RRM measurement at preset measurement intervals in a manner of decreasing preset decreasing amplitude within a fifth preset time period T5, and then perform strategy 2 after the fifth preset time period T5. It should be appreciated that the preset measurement interval is greater than the second measurement interval and, after the fifth preset time period 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 power consumption of the terminal can be further saved. The fifth preset duration T5 may be predefined or set by the network device, similar to the first preset duration T1. The value of the fifth preset duration T5 is not limited in this embodiment of the present application.

In a sixth example, RRM relaxation measurement scenario M is measurement scenario two described above, and RRM relaxation measurement scenario N is measurement scenario one described above. If policy 2 requires more power consumption of the terminal than policy 1, then the target RRM relaxation measurement policy may be policy 1, which maximally saves power consumption of the terminal. If the policy 2 needs to consume less power of the terminal than the policy 1, the target RRM relaxation measurement policy may be to execute the policy 2 in a sixth preset duration T6, and then execute the foregoing policy 1, where the policy 2 is executed in the sixth preset duration T6, so that the power consumption of the terminal may be saved as much as possible; alternatively, the target RRM relaxation measurement strategy may be to perform RRM measurement at preset measurement intervals in a manner of decreasing preset decreasing amplitude within a sixth preset time period T6, and then perform strategy 1 after the sixth preset time period T6. It should be appreciated that the preset measurement interval is greater than the first measurement interval and, after the sixth preset time period 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 power consumption of the terminal can be further saved. The sixth preset duration T6 may be predefined or set by the network device, similar to the first preset duration T1. In this embodiment, the value of the sixth preset duration T6 is not limited, and the sixth preset duration T6 may be the same as or different from the fifth preset duration T5.

As in the foregoing possible first or second implementation manner, the terminal may be switched from the RRM relaxation measurement scenario M to the RRM relaxation measurement scenario N, and the terminal may be directly switched from the RRM relaxation measurement policy M to the RRM relaxation measurement policy N, or may be transitionally switched to the RRM relaxation measurement policy N. The terminal may determine which manner to switch the RRM relaxation measurement policy according to actual requirements, e.g., the power saving requirements of the terminal and/or the communication performance of the terminal.

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

In some embodiments, the terminal may determine the handover criteria to be employed by the target RRM relaxation measurement policy based on the type of traffic being performed. For example, the terminal performs voice service, and in order to ensure call quality, the handover criterion may be a second criterion. In other embodiments, the terminal may determine the handover criteria to be employed by the target RRM relaxation measurement strategy based on its own product type. For example, if the terminal is a portable device (cell phone, tablet, watch, bracelet, etc.), energy saving should be prioritized, then the switching criteria may be the first criteria. In still other embodiments, the terminal may determine the handover criteria to be employed by the target RRM to relax the measurement policy based on its own usage status, e.g., the terminal's power status, mobility status, network status, etc. For example, the terminal turns on the power saving mode, and the switching criterion may be a first criterion. For example, the terminal moves faster, and the handover criterion may be a second criterion in order to ensure the communication quality.

And if the terminal determines the target RRM relaxation measurement strategy based on the first criterion, when the terminal is switched from the high-energy consumption measurement scene to the low-energy consumption measurement scene, the target RRM relaxation measurement strategy is directly switched to the low-energy consumption measurement strategy. For example, the terminal switches from the first measurement scenario or the second measurement scenario to the third measurement scenario, the target RRM relaxes the measurement policy to policy 3.

If the terminal determines the target RRM relaxation measurement strategy based on the second criterion or the third criterion, the target RRM relaxation measurement strategy may be a transition switch to a low energy measurement strategy when the terminal switches from a high energy measurement scenario to a low energy measurement scenario. For example, the terminal switches from the first measurement scenario or the second measurement scenario to the third measurement scenario, then the target RRM may relax the measurement policy by first executing, for example, policy 1 or policy 2 for a preset duration, and then executing policy 3 after the preset duration.

In other words, in the case of switching from a measurement scenario with higher energy consumption to a measurement scenario with lower energy consumption, the terminal may directly execute a policy corresponding to the measurement scenario with lower energy consumption, so as to maximally save the energy consumption of the terminal; or the terminal can transition for a period of time, and then execute a strategy corresponding to a measurement scene with lower energy consumption, so that the communication performance of the terminal is ensured as much as possible while the energy consumption of the terminal is saved.

Similarly, if the terminal determines the target RRM relaxation measurement strategy based on the second criterion, the target RRM relaxation measurement strategy is to switch directly to the high energy consumption measurement strategy when the terminal switches from the low energy consumption measurement scenario to the high energy consumption measurement scenario. For example, the terminal switches from the measurement scenario three to the measurement scenario one or the measurement scenario two, and then the target RRM relaxes the measurement policy to be policy 1 or policy 2.

If the terminal determines the target RRM relaxation measurement strategy based on the first criterion or the third criterion, the target RRM relaxation measurement strategy may be a transition switch to a high energy consumption measurement strategy when the terminal switches from a low energy consumption measurement scenario to a high energy consumption measurement scenario. For example, the terminal switches from the measurement scenario three to the measurement scenario one or the measurement scenario two, and then the target RRM relaxes the measurement policy, for example, policy 3, for a preset duration, and then policy 1 or policy 2 is performed after the preset duration.

Under the condition that the terminal is switched from a measurement scene with lower energy consumption to a measurement scene with higher energy consumption, the terminal directly executes a strategy corresponding to the measurement scene with higher energy consumption so as to maximally ensure the communication performance of the terminal; or the terminal can transition for a period of time, execute the strategy corresponding to the measurement scene with higher energy consumption, and save the energy consumption of the terminal as much as possible while guaranteeing the communication performance of the terminal.

Unlike the first or second implementation, the terminal may also determine the target RRM relaxation measurement policy according to the indication of the network device. That is, as an alternative implementation manner of the foregoing implementation manner one or implementation manner two, the network device may designate a target RRM relaxation measurement scenario for the terminal, and when the terminal switches from the RRM relaxation measurement scenario M to the RRM relaxation measurement scenario N, the terminal performs RRM relaxation measurement using the target RRM relaxation measurement scenario designated by the network device.

For example, S503, the network device may send indication information to the terminal, where the indication information indicates the target RRM relaxation measurement policy to the terminal. It should be appreciated that S503 is an optional step and is therefore illustrated in dashed lines in fig. 5.

The indication information may directly indicate the target RRM relaxation measurement strategy, or may indirectly indicate the target RRM relaxation measurement scenario, and several possible implementations of the indication information are described below, respectively.

The direct indication mode one and the indication information can comprise measurement parameters, and the measurement parameters can comprise one or more parameters of measurement intervals, the number of adjacent cells to be measured and the number of frequency points to be measured of the adjacent cells to be measured. When the terminal switches from the RRM relaxation measurement scenario M to the RRM relaxation measurement scenario N, the terminal may determine a target RRM relaxation measurement policy according to the measurement parameter, and perform RRM relaxation measurement. In other words, the scheme may directly indicate the target RRM relaxation measurement strategy. It will be appreciated that in this case, the network device may send the indication information to the terminal when the terminal switches from RRM relaxation measurement scenario M to RRM relaxation measurement scenario N.

Illustratively, the measurement parameter includes a measurement interval according to which the terminal may perform RRM relaxation measurements for all neighbors. Or the measurement parameter comprises the number L of the neighbor cells to be measured, and the terminal can execute RRM relaxation measurement on the L neighbor cells to be measured according to the measurement parameter. Or the measurement parameter comprises the number K of subcarriers to be measured of the neighbor cell to be measured, and the terminal can execute RRM relaxation measurement on the K subcarriers of the neighbor cell to be measured according to the measurement parameter. For another example, the measurement parameters include a measurement interval and the number L of neighbor cells to be measured, and the terminal may perform RRM relaxation measurement on the L neighbor cells to be measured according to the measurement interval according to the measurement parameters, 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 that the energy saving requirement of the terminal and the communication performance of the terminal can be considered.

In some embodiments, the measurement parameters may be carried in a system message (system information, SI), i.e. the network device may broadcast the SI carrying the measurement parameters, which are sent to the terminal. For example, the measurement parameters may be carried in a system information block (system information block, SIB), such as SIB2. Wherein the measurement parameters may carry cells defined in SIB2, such as cell reselection information (cellreselection) cells in SIB2, or speed state parameter (speedstate reselection parameters) cells in SIB2, or other possible cells; alternatively, the measurement parameters may also carry the newly defined cells in SIB2.

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

The direct indication mode II and the indication information are used for indicating at least one RRM relaxation measurement strategy, and the target RRM relaxation measurement strategy is one RRM relaxation measurement strategy in the at least one RRM relaxation measurement strategy. For example, the indication information indicates an RRM relaxation measurement policy, and the target RRM relaxation measurement policy is the RRM relaxation measurement policy. For example, the indication information indicates multiple RRM relaxation measurement strategies, then the target RRM relaxation measurement strategy may be one RRM relaxation measurement strategy of the multiple RRM relaxation measurement strategies, or may be at least two RRM relaxation measurement strategies of the multiple RRM relaxation measurement strategies.

Illustratively, 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 correspondence between the switching of the measurement scenario and the RRM relaxation measurement strategy may be predefined as in the foregoing table 3. 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 a plurality of relaxation measurement strategies, the terminal starts to perform different RRM relaxation measurement strategies at different moments. For example, the indication information indicates a first RRM relaxation measurement policy and a second RRM relaxation measurement policy, the terminal may start to perform the first RRM relaxation measurement policy at a first time and start to perform the second RRM relaxation measurement policy at a second time.

In some embodiments, the indication information may further include a first time and a second time, wherein the first time is a time when the first RRM relaxation measurement strategy starts to be performed, and the second time is a time when the second RRM relaxation measurement strategy starts to be performed. Or the indication information may further include a first time and a first preset time, where the first time is a time when the first RRM relaxation measurement policy starts to be executed, and the first preset time is a time when the first RRM relaxation measurement policy starts to be executed, and after the first preset time, the terminal starts to execute the second RRM relaxation measurement policy.

In the second direct indication mode, the network device may send indication information to the terminal when the terminal switches measurement scenarios. 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 previously described, the terminal may select one or more RRM relaxation measurement strategies from the plurality of RRM relaxation measurement strategies based on the handover criteria. Alternatively, the network device may send the indication information to the terminal before the terminal switches the measurement scenario. In this case, the system may predefine the correspondence relationship as in table 3 above, and the terminal selects the corresponding RRM relaxation measurement policy after switching from one measurement scenario to another measurement scenario. Or the network device, besides sending indication information indicating at least one RRM relaxation measurement policy to the terminal, also informs the terminal to execute the target relaxation measurement policy indicated by the indication information when a certain measurement scenario switch is satisfied.

The indirect indication manner may include a handover criterion according to which the terminal hands over the RRM relaxation measurement policy, the handover criterion corresponding to the target RRM relaxation measurement policy. In other words, the scheme indirectly indicates the target RRM relaxation measurement strategy through the handover criterion. The switching criteria may include a first criterion, a second criterion, or a third criterion as described above.

In some embodiments, the correspondence of the switching criteria to RRM relaxation measurement strategies under measurement scenario switching may be predefined. When the terminal receives the indication information, the RRM relaxation measurement strategy under the corresponding measurement scene can be determined according to the corresponding relation, and then when the scene is switched, the target RRM relaxation measurement strategy is determined through the switched scene.

In other embodiments, the correspondence between the switching criteria and the switching of the RRM relaxation measurement scenario and the correspondence between the switching of the RRM relaxation measurement scenario and the RRM relaxation measurement strategy may be predefined. And after receiving the indication information, the terminal can determine a target RRM relaxation measurement strategy according to the two corresponding relations.

In a possible implementation, the indication information may also be carried in SIB2 defined cells or RRC signaling, similar to the direct indication approach one.

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

In other embodiments, the indication information may indicate a priority of the terminal service, by which the handover criterion is indicated. For example, defining the service with the highest priority, and preferentially guaranteeing the communication performance of the terminal, namely, the service with the highest priority corresponds to the second criterion; in contrast, the lowest priority traffic corresponds to the first criterion. The terminal may determine a handover criterion according to the priority of the service notified by the network device, thereby determining a target RRM relaxation measurement policy.

In the embodiment of the application, in order to consider the power consumption requirement and the communication performance requirement of the terminal, aiming at the situation that the terminal switches the RRM relaxation measurement scene, the corresponding relation between the switching of the RRM relaxation measurement scene and the RRM relaxation measurement strategy is specified. Therefore, after the terminal switches the RRM relaxation measurement scene, the target RRM relaxation measurement strategy can be determined according to the corresponding relation, and RRM measurement can be executed. Alternatively, the network device may instruct the terminal to switch the RRM relaxation measurement scenario, and then the target RRM relaxation measurement policy to be adopted.

In the embodiments provided in the present application, the method provided in the embodiments of the present application is described from the aspect of interaction between the terminal and the network device, respectively.

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#1and#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 given in Table 1[3].Table 1 gives the power saving gain when extending measurement periodicity.

Table 1.Power saving gain when extending measurement periodicity

	DRX＝0.32	DRX＝0.64	DRX＝1.28s	DRX＝2.56
					N＝4	27.9％	24.75％	19.7％	14.2％
N＝8	32.5％	28.6	23.0％	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 extension is not outstanding.As network may have different preference in different scenario,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 degree or location etc.The relaxation factor can be within the range of{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 agreed that network indicates option a or option b.For option a,it was already agreed at RAN4#93 meeting that UE is not required to meet the intra-frequency and inter-frequency neighbour cellmeasurement requirements for scenario#3.So the UE behaviour 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 criterion is fulfilled.If both criteria are satisfied,we don’t think that UE shall stop measurement in this case.Since network indicates option b to UE,it means that network expects relaxation measurement and expects the measurement results reported by UE.Otherwise network will indicate option a to UE.So if both criteria are 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 measurement for cell reselection shall be considered.Obviously the 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 too short value will reduce the power saving gain.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 parallelRAN2 was discussing the same issue as well[2].

In current specification if Srxlev>S _n o _{nIntraSearchP} and Squal>S _n o _{nIntraSearchQ} 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 _n o _{nIntraSearchP} or Squal<S _n o _{nIntraSearchQ} ,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 relaxed 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 large power consumption.

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 number.It means that the normalized 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 measurement may be impacted.There are two cases to 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 relaxation measurement on the carriers indicated by EMR configuration can still be applied in 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 neighbour 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 about the neighbour cell measurement results when UE is going to 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 technique

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 bycross-slot scheduling.

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

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

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

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

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

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 mainly three scenarios to relax the measurement/cell identification/evaluation requirements.

#1: low mobility scenarios

#2: cell edge scene is not used

#3: low speed + non-edge scene

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

scene #1:

protocol-RRM measurement relaxation lengthening

Scene II:

protocol-RRM measurement relaxation lengthening

Measurement interval scaling factor FFS

Option 1: fixed value

The FFS values of scene #1 and scene #2 are the same

The individual values of scenario #1 and scenario #2 are to be studied further

Option2: network configurable values

Applicability of RRM relaxation method to scene #1 and scene #2: how to relax the measurements is discussed, the power consumption results are discussed in SI phase. Details of the simulation assumptions are in the annex of TS 38.840. The simulation results are shown in Table 1[3 ]. Table 1 gives the power saving gain when the measurement period is extended.

TABLE 1 Power saving gain for extended measurement period

It can be seen that extending the measurement interval by a factor of N can bring about a significant energy saving gain. The gain of 8-fold expansion versus 4-fold expansion is not apparent when DRX is larger. Since networks may have different preferences in different scenarios, a flexible approach is to configure the expansion factor by network. For example, the network may configure different relaxation factors for different scenarios. Alternatively, the relaxation factor may also take into account the degree of movement or the location of the UE, etc. The relaxation factor has a value in the range of {2,8}. Suggestion 1: for scenarios #1 and #2, the expansion factor may be loosely measured per network configuration. In the last conference, RAN2 sends an LS to RAN4[2 ].

Protocol replication is as follows:

RAN2 discusses the problems associated with NR power saving RRM measurements and achieves the following protocol: 1. the network side broadcasts corresponding parameters of the relaxation triggering criteria, and starts RRM to measure relaxation characteristics. 2. When the network configures both low mobility and non-edge criteria parameters. The UE may make measurement relaxation according to one of the following options indicated by the network: option a UE uses low mobility criteria and non-cell edge criteria, namely: only if both conditions are met, the UE can perform relaxation. The specific relaxation behavior depends on the discussions and decisions of RAN 4; option b the UE uses low mobility criteria or non-cell edge criteria (selection may be left to UE implementation), namely: the UE may relax when low mobility or non-cell edge criteria are met. While the detailed relaxation behavior is the same as the case where the network only configures the criteria

RAN2 has agreed to either network indication option a or option b. For option a, already agreed on the RAN4#93 conference, the UE is not required to meet the on-channel and off-channel neighbor measurement requirements of scenario # 3. Thus, the behavior of the UE is explicit. For option b, the UE may perform relaxation when the low mobility or non-cell edge criteria are met when the network configures parameters of both the low mobility and non-cell edge criteria. If both criteria are met, we consider that in this case the UE does not stop the measurement. Since the network indicates option b to the UE, this means that the network expects to relax the measurements and expects the UE to report the measurement results. Otherwise, the network will indicate option a to the UE. Thus, if both criteria are met, the UE may select either one, depending on the UE implementation.

Suggestion 2: when the network is configured with both low mobility and non-edge cell standard parameters, -if the network indicates option a, the UE stops co-frequency and inter-frequency neighbor measurements when both standards are met. -if the network indicates option b, the UE performs a corresponding loose measurement according to which conditions are met. If both conditions are met, selection of one (low mobility or non-edge cell) and corresponding loose measurement is performed by the UE. In NB-IoT, the following loosely latency monitoring 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 metric rules when the UE is required to perform on-frequency or off-frequency measurements according to the measurement rules in section 5.2.4.2 or 5.2.4.2a, the UE may choose not to perform on-frequency or off-frequency measurements in the following cases: -the loose monitoring criteria in section 5.2.4.12.1 are met during TSearchDeltaP, and-less than 24 hours have elapsed since the last cell reselection measurement was performed, and-the UE performs at least TSearchDeltaP co-or inter-frequency measurements after selecting or reselecting to a new cell.

In the power saving mode, if both conditions are met and the network indicates option a, the UE will stop both co-frequency and inter-frequency neighbor measurements. In this case, the interval from the last cell reselection measurement should be considered. It is apparent that 24 hours is not suitable for a power saving terminal. This value should take into account network deployment, propagation environment, UE movement direction, UE speed, UE location, etc. Too long a periodic configuration may affect mobility performance of the UE, and too short a periodic configuration may reduce power saving gain. In general, we consider the time interval for which the measurement is relaxed (measurement is stopped) because the last measurement cell reselection is on the order of minutes. Suggestion 3: the time interval for measurement relaxation (stopping measurement) is in the order of minutes from the last cell reselection measurement. The inter-frequency layer RAN4, where the relaxation priority of RRM measurements is high, discusses RRM measurements where the inter-frequency layer priority is higher.

"RRM measurement relaxes high priority different frequency layer option 1: "when Srxlev > snondin setarchp and square > snondin setarchq, it is not desirable to relax the current measurement delay requirements for higher priority inter-frequency measurements. "when Srxlev d SnonIntraSearchP or Squal d SnonIntraSearchQ, the relaxed measurement requirements for the high priority frequency layer are the same as for the peer/low priority frequency layer. Alternative 2: "in a high-speed mobile scenario, measurement of high priority carriers should not relax (scenario # 2) option 3: "the higher priority carriers should not be relaxed.

1. Whether the high priority frequency bins are loose or not depends on the network configuration. Further research is needed as to how to perform the configuration. RAN2 is discussing a high priority measurement relaxation indication and wants to ask RAN4 about the high priority carrier relaxation behavior: a kind of electronic device is disclosed. For the case of Srxlev > snonintrasearch p and square > snonintrasearch q, if the relaxation criteria defined by RAN2 are met, whether RAN4 envisages further relaxation of the measurement of the higher priority carrier than the huge_priority_search? And II, performing secondary treatment. For the case of Srxlev < snonintrasetp or square < snonintrasetq, if the relaxation criteria defined by RAN2 are met, whether there is performance or system advantage to relax only the measurements of the equal/low priority carriers, but not the measurements of the high priority carriers?

In the current specification, if Srxlev > snonlin search p and square > snonlin search q, the UE should search for the different system E-UTRAN layer with higher priority at least in each of the huge_priority_searches, where huge_priority_search= (60 x n layers) seconds later takes effect. For this case the requirements have been relaxed so the benefit of further relaxation is negligible. For Srxlev < SnonenSearchP or Square <

In the case of snonintrasetq, the UE behavior is to measure the inter-frequency layer with higher, same or lower priority layer. In the current specification, the measurement requirements for high priority, equal priority or low priority are the same in this case. In a power saving scenario, if the measurement of the high priority layer is relaxed, the power saving benefits can be foreseen (as shown in table 1). Furthermore, since the measurement is relaxed to a higher priority, the validity of the measurement results is not a big problem. Since the power saving trigger criteria is specified as low.

Suggestion 4: when Srxlev > snonintrasetp and square > snonintrasetq, the current measurement delay requirement is not relaxed for high priority inter-frequency measurements. When Srxlev d SnonIntraSearchP or Squal d SnonIntraSearchQ, the high priority frequency layer relaxed measurement requirements are different from the equal/low priority frequency layer relaxed measurement requirements.

Reducing the number of frequency layers is essential from the UE point of view and the paging occasion cannot be missed. Theoretically, the UE may make the on-channel measurements at paging occasions, which means that the on-channel measurements do not introduce extra large power consumption. For inter-frequency measurements, the UE needs to wake up additionally during DRX-OFF to avoid page reception degradation. It is known that the measurement requirement for inter-frequency is scaled with the number of frequencies. I.e. when the number of different frequency layers is greater than 1, the normalized power is not raised.

Suggestion 5: reducing the number of different frequency layers for idle state measurement cannot bring energy saving gain.

Effects on early measurement reporting CA/DC enhancements introduce an early reporting measurement reporting function. The purpose of EMR is to expedite CA/DC establishment when the UE enters a connected state. If the UE is in power saving mode, normal measurements may be affected. There are two situations that need to be discussed separately. In scenes #1 and #2, a relaxation measurement should be performed. It is understood that EMR is not an urgent function and that the measurement of relaxation measurements on the carrier indicated by the EMR configuration can still be applied to EMR.

Proposal 6: in scenes #1 and #2, the measurement results from the relaxation measurement are still applicable to EMR. In scenario #3, the UE may stop neighbor cell measurement when the UE is in the power saving mode. However, if the UE is also configured with EMR configuration in RRC release, the UE has no information about neighbor cell measurement results when the UE is ready to enter RRC connected mode. In this case, the UE may need to establish CA or DC due to traffic load. EMR measurements are reasonable. In view of power saving, the UE may make a relaxation measurement.

Suggestion 7: in scenario #3, the UE will perform a relaxation measurement when the UE configures EMR. Effect of l cross-slot scheduling energy saving technique on RRM RAN1 last conference is discussing cross-slot scheduling energy saving. The framework of the BWP switch is basically as follows.

Summarizing: "if 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 a minimum scheduling offset limit applied to the target BWP. And (3) injection: the specification does not need to be changed.

Thus, in RAN4, there is no need to discuss extending BWP handover delays. In other words, the DCI-based BWP handover delay requirement in RAN4 is unchanged. It is suggested 8 that the DCI based BWP handover delay requirement in ran4 is not affected by cross-slot scheduling.

The problem of measurement relaxation in energy conservation is discussed herein. The proposal is as follows: suggestion 1: for scenarios #1 and #2, the expansion factor may be loosely measured per network configuration.

Suggestion 2: when the network is configured with both low mobility and non-edge cell standard parameters, -if the network indicates option a, the UE stops co-frequency and inter-frequency neighbor measurements when both standards are met. -if the network indicates option b, the UE performs a corresponding loose measurement according to which conditions are met. If both conditions are met, selection of one (low mobility or non-edge cell) and corresponding loose measurement is performed by the UE.

Suggestion 3: the time interval for measurement relaxation (stopping measurement) is in the order of minutes from the last cell reselection measurement.

Proposal 6: in scenes #1 and #2, the measurement results from the relaxation measurement are still applicable to EMR.

Suggestion 7: in scenario #3, the UE will perform a relaxation measurement when the UE configures EMR. It is suggested 8 that the DCI based BWP handover delay requirement in ran4 is not affected by cross-slot scheduling.
