Relaxation measurement method and communication device

Cross Reference to Related Applications

The present application claims priority from chinese patent office, application number 202010322734.7, application name "a method of processing measurement relaxation high priority data, UE and network device" filed 22 months 4 in 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. If the signal amplitude value of the serving cell is larger than the inter-frequency/inter-system measurement signal amplitude threshold and the quality of the signal of the serving cell is larger than the inter-frequency/inter-system measurement signal strength threshold, the terminal searches the cell of the frequency point with higher priority at least at intervals of seconds. In contrast, if the signal amplitude value of the serving cell is smaller than or equal to the inter-frequency/inter-system measurement signal amplitude threshold, or the signal quality of the serving cell is smaller than the inter-frequency/inter-system measurement signal strength threshold, the terminal will search for and measure the cells with higher, lower or equal priority frequency points. And then the terminal can perform cell reselection according to the measurement result. It should be understood that the inter-frequency/inter-system measurement signal amplitude threshold and the inter-frequency/inter-system measurement signal strength threshold are the thresholds for performing cell measurements. The priority here refers to the priority of the frequency points, and the cell of the high priority frequency point is also referred to as a high priority cell.

In order to reduce the power consumption of the terminal, the concept of RRM relaxation measurement (RRM measurement relax) is currently proposed, i.e. if the terminal is in RRM relaxation measurement scenario, 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). But for terminals in RRM relaxation measurement scenarios, there is no further solution how to perform relaxation measurements on high priority frequency points.

Disclosure of Invention

The application provides a relaxation measurement method and a communication device, which are used for providing a strategy of relaxation measurement based on the priority of frequency points so as to consider the energy consumption requirement and the load gain requirement of a 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 determines the signal quality of a serving cell, determines a target measurement strategy for measuring a target frequency point according to the signal quality of the serving cell and a relaxation measurement threshold, and executes relaxation measurement on the target frequency point according to the target measurement strategy; the terminal is in a first relaxed measurement scene, and the relaxed measurement threshold is larger than a measurement access threshold, wherein the measurement access threshold is a threshold adopted by the terminal which is not in the first relaxed measurement scene for executing measurement.

The scheme can determine a relaxation measurement strategy adopted by carrying out relaxation measurement on the target frequency point through a relaxation measurement threshold aiming at the terminal in a relaxation measurement scene. The priority of the target frequency point may be higher than the priority of the frequency point of the serving cell, or may be lower than or equal to the priority of the frequency point of the serving cell, and the relaxation measurement threshold may be flexibly set for the target frequency points with different priorities, so as to consider the communication performance and the energy saving requirement of the terminal.

In a possible implementation manner, the determining, by the terminal, that the signal quality of the serving cell is greater than the relaxed measurement threshold, and determining, by the terminal, a target measurement policy for measuring a target frequency point according to the signal quality of the serving cell and the relaxed measurement threshold, includes:

the terminal determines to execute measurement on the target frequency point according to a first value of a measurement interval, wherein the priority of the target frequency point is higher than that of the frequency point of the service cell, the first value is larger than a first initial value, and the first initial value is the value of the measurement interval adopted by the terminal which is not in a relaxation measurement scene to execute measurement on the target frequency point; or the terminal determines that measurement is not performed on the target frequency point, wherein the priority of the target frequency point is the same as that of the frequency point of the service cell, or the priority of the target frequency point is lower than that of the frequency point of the service cell.

In this scheme, if the signal quality of the serving cell is greater than the relaxed measurement threshold, the signal quality of the serving cell is better, and the terminal may not reselect the cell at this time. Therefore, when the terminal is in a relaxation measurement scene, the terminal can perform relaxation measurement on the target frequency points with high priority, and does not perform relaxation measurement on the target frequency points with the same or low priority, so that the energy consumption of the terminal is further reduced.

In a possible implementation manner, the terminal determines that the signal quality of the serving cell is less than or equal to the relaxed measurement threshold, and determines a target measurement policy for measuring a target frequency point according to the signal quality of the serving cell and the relaxed measurement threshold, where the determining includes:

and the terminal determines to execute measurement on the target frequency point according to a second value of a measurement interval, wherein the second value is larger than a second initial value of the measurement interval, and the second initial value is a value adopted by the terminal which is not in a relaxed measurement scene to execute RRM measurement on the target frequency point, wherein the priority of the target frequency point is higher than the priority of the frequency point of the service cell, or the priority of the target frequency point is equal to the priority of the frequency point of the service cell, or the priority of the target frequency point is lower than the priority of the frequency point of the service cell.

In the scheme, if the terminal is in a relaxed measurement scene, the signal quality of the serving cell is stable. Although the signal quality of the serving cell is smaller than or equal to the relaxation measurement threshold, that is, the signal quality of the serving cell is poor, since the signal quality of the serving cell is stable, the terminal can perform relaxation measurement on the target frequency points of each priority, so as to reduce the energy consumption of the terminal as much as possible.

In one possible implementation, the target frequency point has a higher priority than the frequency point of the serving cell, and the second value is smaller than the first value. It should be understood that, when the second value is smaller than the first value, that is, the signal quality of the serving cell is relatively stable, the better the signal quality of the serving cell is, the longer the measurement interval for measuring the high-priority frequency point is, so as to further reduce the energy consumption of the terminal.

In one possible implementation, the first value is N1 times the first initial value, and N1 is an integer greater than 1; or the first value is the sum of the first initial value and a first adjustment factor, the first adjustment factor is located in a first preset range, and the first adjustment factor is greater than 0.

In one possible implementation, the second value is 1/N2 times the second initial value, and the N2 is an integer less than 1; or the second value is the sum of the second initial value and a second adjustment factor, the second adjustment factor is located in a first preset range, and the second adjustment factor is greater than 0.

Since the first initial value and the second initial value are both known as the values of measurement intervals adopted by the terminal which is not in a relaxed measurement scene to perform measurement on the target frequency point, namely the values are defined by the existing protocol. Therefore, the first value is determined through the first initial value, and the second value is determined through the second initial value, so that compatibility with the existing protocol is facilitated.

In one possible implementation, there are multiple relaxation measurement scenarios, where the first value or the second value corresponding to different relaxation measurement scenarios are the same; or the first value or the second value corresponding to different relaxation measurement scenes is different. In the scheme, the first value or the second value corresponding to different relaxation measurement scenes is the same, so that the scheme is simpler. The first value or the second value corresponding to different relaxation measurement scenes is different, so that the requirements of communication performance and energy consumption of the terminal are met.

In one possible implementation, the method further includes:

the terminal receives indication information from network equipment, wherein the indication information is used for indicating the terminal to execute relaxation measurement on a target frequency point, and the priority of the target frequency point is higher than that of the service cell. The terminal can execute relaxation measurement on the high-priority frequency point according to the instruction of the base station so as to consider the energy consumption requirement and the communication performance requirement of the terminal.

In one possible implementation, the relaxation measurement includes: RRM relaxation measurements and/or RLM relaxation measurements.

In one possible implementation, the method further includes:

after the terminal performs measurement on the target frequency point, the terminal reselects to a target cell, wherein the cell reselection threshold of the target cell is larger than the cell reselection threshold adopted by the terminal which is not in a relaxed measurement scene for cell reselection. In the scheme, the terminal can relax cell reselection, namely improve the cell reselection threshold, so that the terminal can avoid frequent reselection of the cell.

In one possible implementation, the cell reselection threshold includes one or more of a cell reselection signal amplitude threshold, a cell reselection signal strength threshold, and a cell reselection time interval threshold. In the scheme, the terminal can further relax the cell reselection time interval and further reduce the times of cell reselection by the terminal.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

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.

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.

In addition, the embodiment of the application can be also applied to other communication technologies facing the future. The network architecture and the service scenario described in the present application are for more clearly describing the technical solution of the present application, and do not constitute a limitation on the technical solution provided in the present application, and as a person of ordinary skill in the art can know, with evolution of the network architecture and appearance of a new service scenario, the technical solution provided in the present application is also applicable to similar technical problems.

Compared to long term evolution (long term evolution, LTE) systems, which have only two RRC states, rrc_idle and rrc_connected, new Radio (NR) systems introduce a new state (rrc_active) to meet the requirements of low latency and low power consumption. 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.

After the terminal performs RRM measurement on the neighbor cells on the target frequency point (including the same-frequency point and/or different-frequency point), the terminal can reselect the cells to ensure the communication quality as much as possible. For example, after the terminal performs RRM measurements, it may switch to a high priority cell. Here, the priority refers to a priority of a frequency point and/or a carrier, and cells of the same frequency point and/or carrier on the same radio access technology (radioaccess technology, RAT) have the same priority, and cell priorities of different frequency points and/or carriers may be the same or different. The cells of the high-priority frequency points and/or the carriers can be simply called high-priority cells, and similarly, the cells of the low-priority frequency points and/or the carriers can be simply called low-priority cells, and if the cells respectively corresponding to the two frequency points with the same level can be simply called equal-priority cells.

According to the relative relation between the priority of the target frequency point and the priority of the service frequency point (the frequency point where the service cell is located), the target frequency point is divided into a high-priority target frequency point, a target frequency point with the same priority and a target frequency point with low priority. It should be appreciated that high priority target frequency points, i.e., target frequency points having a priority higher than the priority of the service frequency points. The target frequency points with the same priority, namely the target frequency points with the same priority as the service frequency points. And the low-priority target frequency point is a target frequency point with a priority lower than that of the service frequency point.

The network device may define the priority of each frequency point, for example, the network device may determine the priority of a frequency point according to the network coverage of the frequency point and/or the number of users under the frequency point. For example, 5G has a higher priority than 4G, and 4G has a higher priority than 3G. For another example, if the number of users in a certain frequency point is greater than the number of users in another frequency point, the priority of the frequency point is lower than the priority of the other frequency point. The network device may inform the terminal of the priority of the respective frequency points, e.g. the network device may broadcast the priority of the respective frequency points.

The terminal can perform cell reselection according to the priority of the frequency point. For example, the terminal can switch from a cell with a large number of frequency points to a cell with a small number of frequency points to meet the requirement of load balancing. For another example, the operator may default to the terminal using the 5G network, and the network device may set the priority of the 5G network to the highest priority.

Before the terminal reselects the cell, RRM measurement can be performed on the service frequency point and the adjacent cell frequency point. In some embodiments of the present invention, in some embodiments,

corresponding RRM measurement triggering conditions are set for each priority frequency point, and the terminal measures the priority frequency point corresponding to the triggering conditions under the condition that certain triggering conditions are met. For example, the trigger condition set for the high priority frequency point is that the signal amplitude of the serving cell is greater than the inter-frequency/inter-system measurement signal amplitude threshold, and the signal strength of the serving cell is greater than the inter-frequency/inter-system measurement signal strength threshold. The trigger condition set by the high-priority frequency point is met, the terminal performs RRM measurement on the high-priority frequency point, and the low-priority frequency point or the equal-priority frequency point is not measured.

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. I.e. the terminal is in a certain relaxation measurement scenario, the terminal may perform RRM relaxation measurements. For example, the terminal may decrease the number of RRM measurements (e.g., increase the time interval of RRM measurements), and for example, the terminal may decrease the measurement object (e.g., the terminal decreases the number of target frequency points to be measured, or the terminal decreases the number of neighbor cells to be measured).

When the terminal is in a relaxation measurement scene, such as the terminal is stationary or moves at a low speed, the signal quality of the serving cell and the neighbor cell are relatively stable, and the signal quality is kept in a certain range for a long time, so that the terminal can perform RRM relaxation measurement on the serving cell and the neighbor cell. In this case, if the signal amplitude of the serving cell is greater than the inter-frequency/inter-system measurement amplitude threshold and the signal quality of the serving cell is greater than the inter-frequency/inter-system measurement signal strength threshold, the signal quality of the serving cell is higher. The terminal can be provided with stable and better service, so that the terminal does not need to reselect to the adjacent cell. In order to save the power consumption of the terminal, RRM relaxation measurement may be further performed on the high priority frequency points. However, there is no further solution for how to perform relaxation measurement on the high-priority frequency points by the terminal in the RRM relaxation measurement scenario.

In view of this, the embodiment of the present application provides a relaxation measurement method, which specifies, for a terminal in a relaxation measurement scenario, a relaxation measurement policy (hereinafter, also referred to as a relaxation measurement policy) adopted by the terminal to measure a high-priority frequency point (hereinafter, also referred to as a high-priority cell), so as to consider both a power consumption requirement of the terminal and a load balancing requirement.

Before describing the technical solutions provided by the embodiments of the present application, some terms in the embodiments of the present application are explained below for the convenience of those skilled in the art.

1) The signal quality, which is the measurement result obtained by performing RRM measurement for the terminal with respect to the cell, may include one or more of the following signal quality parameters:

signal amplitude (Srxlev, herein S _rxlev Indicated), signal strength (square, herein S _qual Representation), reference signal received power (reference signal received power, RSRP), reference signal received quality (reference signal received quality, RSRQ), signal-to-noise ratio (signal to noise ratio, SNR), signal-to-interference-and-noise ratio (signal to interference plus noise ratio, SINR), and the like.

2) And the measurement configuration information of the cell is used for the terminal equipment accessing the cell to execute RRM measurement. Wherein the measurement configuration information includes the priority (cell reselection priority) of the frequency point of the cell and the measurement threshold(S _search ). Wherein the measurement threshold may include a common frequency measurement threshold (Sintrasearch, herein S _intrasearch Indicated), and inter-frequency/inter-system measurement threshold (snondintersearch, herein S _{nonintrasearch} Representation). The signal quality can be represented by the signal amplitude, and if the signal amplitude is larger than the same-frequency measurement threshold, the signal quality is better. The signal quality can also be represented by the signal strength, and if the signal strength is larger than the inter-frequency/inter-system measurement threshold, the signal quality is better. Or the signal quality can be represented by the signal amplitude and the signal strength, if the signal amplitude is larger than the same-frequency measurement threshold and the signal strength is larger than the different-frequency/different-system measurement threshold, the signal quality is better.

Illustratively, when the signal quality is represented by a signal amplitude and a signal strength, the on-channel measurement threshold comprises: common frequency measurement signal amplitude threshold (Sintraearchp, herein S _intrasearch P) and a common frequency measurement signal strength threshold (sintraearchq, herein S _intrasearch Q) represents the following formula. Wherein S is _intrasearch P is used for indicating the signal amplitude threshold of the same-frequency measurement, S _intrasearch Q is used to indicate the signal strength threshold for co-channel measurement. In the current measurement strategy, when a terminal device taking the cell as a serving cell measures that the signal quality of the cell meets the following conditions, the terminal device starts to perform measurement on a neighboring cell on a serving frequency point (frequency point where the serving cell is located): signal amplitude in signal quality of the cell (S _rxlev ) Greater than the S _intrasearch P, and the signal strength in the signal quality of the cell (S _qual ) Greater than the S _intrasearch Q。

Meanwhile, the inter-frequency/inter-system measurement threshold includes: inter-frequency measurement signal amplitude threshold (snondinterrasearchp, herein S _{nonintrasearch} P) and an inter-frequency measurement signal strength threshold (snondinterearchq, herein S _{nonintrasearch} Q) represents the following formula. Wherein S is _{nonintrasearch} P is used to indicate the inter-frequency/inter-system measured signal amplitude threshold (This specifies the Srxlev threshold (in dB) for NR inter-frequency and inter-RAT measurement ements)，S _{nonintrasearch} Q is used to indicate the signal strength threshold (This specifies the Squal threshold (in dB) for NR inter-frequency and inter-RAT measurements for inter-frequency/inter-system measurements. In the current measurement strategy, when a terminal device taking the cell as a serving cell measures that the signal quality of the cell meets the following conditions, the terminal device performs measurement on a neighboring cell on a high-priority target frequency point: signal amplitude in signal quality of the cell (S _rxlev ) Greater than the S _{nonintrasearch} P, and the signal strength in the signal quality of the cell (S _qual ) Greater than the S _{nonintrasearch} Q is a group; and when the cell signal quality measured by the terminal equipment does not meet the condition, the terminal equipment performs measurement on the adjacent cells on the high-priority target frequency point, the equal-priority target frequency point and the low-priority target frequency point.

3) A cell reselection threshold, which may include an inter-frequency/inter-system high priority RSRP reselection threshold (denoted herein by ThreshX, highP), and an inter-frequency/inter-system high priority RSRQ reselection threshold (denoted herein by ThreshX, highQ). ThreshX, highP is used to indicate the signal amplitude threshold for inter-frequency/inter-system reselection, threshX, highQ is used to indicate the signal strength threshold for inter-frequency/inter-system reselection. In the current cell reselection process, for the reselection of the cell where the high-priority frequency point is located, when the terminal measures that the signal quality of the target cell meets the following conditions, the terminal reselects to the target cell in a cell reselection time interval: signal amplitude in signal quality of target cell (S _rxlev ) Greater than the hreshX, highP; alternatively, the signal strength in the signal quality of the target cell (S _qual ) Greater than said ThreshX, highQ and the terminal has a dropped network of more than 1s in the current serving cell, i.e. the terminal is not connected to the base station for at least 1 s.

Among the cell reselection thresholds may be a serving cell low priority RSRP threshold (herein ThreshServing, lowP) and a serving cell low priority RSRQ threshold (herein ThreshServing, lowQ). ThreshServing, lowP is used for indicating the signal amplitude threshold of the same-frequency reselection, and ThreshServing, lowQ is used for indicating the signal strength threshold of the same-frequency reselection. In the current cell reselection process, for the reselection of a cell where a frequency point with the same priority is located, when the terminal measures that the signal quality of a target cell meets the following conditions, the terminal drops the network from a service cell for more than 1s, when the signal strength of the service cell is less than ThreshServing, lowQ, and the target cell meets the condition that the signal strength is greater than ThreshX and LowQ in a treselection rat_relay; or the signal amplitude of the current serving cell is smaller than ThreshServing, lowP, the target cell satisfies that the signal amplitude value is larger than ThreshX and LowP in the treselection rat, and the terminal has network drop of more than 1s in the current serving cell.

4) Cell reselection time interval, (denoted herein as treselection rat), time threshold for the terminal to reselect to the target cell. That is, the signal amplitude in the signal quality of the target cell (S _rxlev ) Above said hreshX, highP, the terminal reselects the target cell beyond the cell reselection time interval. Alternatively, in the cell reselection time interval, the signal strength in the signal quality of the target cell (S _qual ) And the terminal is larger than ThreshX, highQ, and has network drop of more than 1s in the current service cell, and the terminal reselects the target cell.

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 following takes the application of this technical solution to RRM measurement as an example.

The following describes the technical scheme provided by the embodiment of the application 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 a relaxation measurement method according to an embodiment of the present application is shown in the following description, and the method is performed 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, a terminal determines the signal quality of a service cell, wherein the terminal is in a first RRM relaxation measurement scene;

s502, the terminal determines a target relaxation measurement strategy of each priority frequency point according to the signal quality and the relaxation measurement threshold of the serving cell, and executes RRM relaxation measurement according to the target relaxation measurement strategy.

In the embodiment of the present application, RRM relaxation measurement may be understood that when the terminal performs RRM relaxation measurement, the terminal may reduce the measurement objects (for example, 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 embodiment of the application aims at setting corresponding RRM relaxation measurement strategies for each priority frequency point for the terminal in the RRM relaxation measurement scene. It should be understood that 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 these measurement scenarios, the terminal may perform RRM relaxation measurements. Several possible RRM relaxation measurement scenarios are listed below. Referring to table 2, three relaxation measurement scenarios and corresponding relaxation measurement strategies are illustrated.

TABLE 2

As shown in table 2, a relaxation scenario one, a terminal stationary or a low-speed movement is measured. In this scenario, the signal quality change of the serving cell of the terminal does not exceed the set threshold 1, and the signal quality of the serving cell and the signal quality of the neighboring cell are relatively stable and 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 neighboring cell.

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

The measurement relaxes the scene three, the terminal is not at the cell edge and the terminal is stationary or moving at low speed. In this scenario, the signal quality of the serving cell is higher than the set threshold 3, and the signal quality change of the serving cell does not exceed the set threshold 1, i.e. the signal quality of the serving cell is higher, so that stable and better service can be provided for the terminal, the signal quality of the serving cell and the signal quality of the neighboring cell are both stable, the signal quality of the serving cell and the signal quality of the neighboring cell are kept within a certain range for a long time, the terminal can perform RRM relaxation measurement on the serving cell, and RRM measurement on the neighboring cell is not performed.

It should be appreciated that the first measurement interval and the second measurement interval in table 2 are both greater than the measurement interval corresponding to the RRM measurement relaxation scenario where the terminal is not in. In table 2, strategy 1 and strategy 2 may be the same, for example, the first measurement interval and the second measurement interval are the same. Or in table 2, strategy 1 and strategy 2 may also be different, 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 like. It should be noted that, table 2 illustrates the RRM measurement strategy only with a measurement interval, i.e. one measurement parameter, and in a specific implementation, the RRM measurement strategy may include a plurality of measurement parameters.

In the RRM measurement process, the terminal can measure the neighbor cells on the low-priority target frequency point and the target frequency point with the same priority so as to meet the requirement of cell coverage. And the terminal measures the neighbor cells on the high-priority target frequency point so as to obtain better service. And when the triggering condition corresponding to a priority frequency point is met, the terminal measures the priority frequency point. In order to give consideration to the cell coverage problem and the service quality problem of the terminal equipment, the triggering conditions of the terminal equipment for measuring the adjacent cells of different priority target frequency points are different. For example, please refer to table 3, which is a relation between the trigger condition and the RRM measurement object.

TABLE 3 Table 3

It should be understood that a certain trigger condition is satisfied, and the terminal performs RRM measurement on the RRM measurement object corresponding to the trigger condition according to a preset measurement interval. For example, when the terminal determines that the signal quality of the serving cell is greater than the inter-frequency/inter-system measurement threshold, only the neighbor cell on the high-priority target frequency point is measured; and when the terminal equipment determines that the signal quality is not greater than the inter-frequency/inter-system measurement threshold, measuring the neighbor cells on the high-priority target frequency point, the equal-priority target frequency point and the low-priority target frequency point.

In order to further save the energy consumption of the terminal, when the terminal is in the RRM measurement relaxation scene, relaxation measurement can be further performed on each priority frequency point. A relaxation measurement strategy (hereinafter referred to as a target relaxation measurement strategy) that may be adopted by the terminal for each priority frequency bin in the respective RRM measurement relaxation scenarios is described below. In the following description, taking the signal quality as represented by signal amplitude and signal strength as an example, the trigger condition in table 3 can be understood as S of the serving cell _rxlev Is larger than the amplitude threshold S of the measurement signal of the different frequency/different system _{nonintrasearch} P, and S of serving cell _qual Greater than the inter-frequency/inter-system measurement signal strength threshold S _{nonintrasearch} Q represents. The second trigger condition can be S _rxlev Less than or equal to S _{nonintrasearch} P, or square is less than or equal to S _{nonintrasearch} Q。

For example, the terminal is in a stationary or low-speed moving scene (measurement relaxation scene one), S _rxlev Greater than S _{nonintrasearch} P and S _qual Greater than S _{nonintrasearch} Q. In this case, the signal quality of the serving cell is higher, the signal quality of the serving cell and the signal quality of the neighbor cell are both relatively stable, and the terminal may not need to reselect to the neighbor cell. Therefore, in order to reduce the power consumption of the terminal, RRM relaxation measurement may be further performed on the high priority frequency points, that is, RRM measurement may be performed on the high priority frequency points at a longer measurement interval than that adopted when not in the relaxation measurement scenario, and RRM measurement may not be performed on the low priority frequency points or the same priority frequency points. That is, the terminal in the relaxation measurement scene is not in accordance with the ratio And carrying out RRM measurement on the high-priority frequency points at a measurement interval with longer measurement interval adopted when the measurement scene is in a relaxed state.

Or the terminal is in the measurement relaxation scene one, S _rxlev Less than or equal to S _{nonintrasearch} P and S _qual Less than or equal to S _{nonintrasearch} Q. The quality of the serving cell may be considered poor and the terminal may reselect to the neighbor cell in order to obtain a stable and better service. The terminal will search for and measure higher, lower or equal priority frequency points, i.e. the terminal may perform RRM measurements on the neighbor cells. In this case, since the terminal is in the measurement relaxation scenario one, the signal quality of the serving cell is relatively stable, and in order to reduce the power consumption of the terminal, the terminal may also perform RRM relaxation measurement on the neighboring cell. RRM measurements are performed, for example, for high priority frequency bins at longer measurement intervals than would be employed if not in a measurement relaxation scenario. Also for example, RRM measurements may be performed on equally-prioritized frequency bins and low-prioritized frequency bins at longer measurement intervals than would be employed if the measurement was not in a relaxed scenario of measurement. It should be appreciated that the measurement interval employed for RRM measurements on high priority frequency points is less than the measurement interval employed for RRM measurements on equal priority frequency points and low priority frequency points. The measurement intervals adopted by the RRM measurement of the frequency points with the same priority and the frequency points with the low priority can be the same or different.

The terminal can meet the first trigger condition or the second trigger condition in any RRM measurement relaxation scene, namely, the terminal can further carry out relaxation measurement on each priority frequency point in any RRM measurement relaxation scene. A relaxation measurement strategy (hereinafter referred to as a target relaxation measurement strategy) that may be adopted by the terminal for each priority frequency bin in the respective RRM measurement relaxation scenarios is described below.

For example, please refer to table 4, for a target relaxation measurement policy corresponding to each high-priority frequency point under different trigger conditions in the relaxation scenario of the first RRM measurement. The first RRM measurement relaxation scenario is any one of the three measurement relaxation scenarios shown in table 2. That is, the RRM relaxation measurement strategy shown in table 4 is independent of what RRM relaxation measurement scenario, that is, the target relaxation measurement strategy corresponding to the same priority frequency point is the same under the same trigger condition in different RRM relaxation measurement scenarios.

TABLE 4 Table 4

Wherein, the first target measurement interval in table 4 is larger than the first preset measurement interval, which can reduce the measurement times of high priority and save the energy consumption of the terminal. Similarly, the second target measurement interval is larger than the second preset measurement interval, and the third target measurement interval is larger than the third preset measurement interval, so that the energy consumption of the terminal is saved. It is understood that the first, second and third preset measurement intervals may be start values of preset measurement intervals. The preset measurement interval corresponding to the frequency point with the same priority and the preset measurement interval corresponding to the frequency point with the low priority may be different or the same (the table 4 is taken as an example, and all the preset measurement intervals are third preset measurement intervals). Similarly, the target measurement intervals corresponding to the frequency points of the same priority may be different from or the same as the target measurement intervals corresponding to the frequency points of the low priority (the third target measurement intervals are all examples in table 4).

In some embodiments, measurement intervals (e.g., the first preset measurement interval to the third preset measurement interval in table 4) used by the terminal to perform RRM measurement on the high priority frequency point, the equal priority frequency point, or the low priority frequency point, respectively, under each trigger condition are predefined. That is, a search period for the terminal to search for each priority frequency point may be predefined. Of course, the first preset measurement interval to the third preset measurement interval may also be predetermined by the terminal and the network device, or the network device is configured for the terminal, which is not limited in the embodiment of the present application. It should be appreciated that the first to third preset measurement intervals are corresponding measurement admission thresholds, i.e. thresholds employed by terminals not in a relaxed measurement scenario to perform measurements.

The relationship between the first target measurement interval and the first preset measurement interval and the second target measurement interval and the second preset measurement interval is described below under different trigger conditions.

For convenience of description, hereinafter, in the case where the trigger condition one will be satisfied, the measurement interval (e.g., the first preset measurement interval in table 4) adopted by the terminal for RRM measurement for the high priority frequency point uniformly adopts T _{higher_priority_search} In contrast, the measurement interval (e.g., the first target measurement interval in Table 4) used for RRM relaxation measurement of high priority frequency points is represented by T _{higher_priority_search_relax} Schematic representation. It is to be understood that T _{higher_priority_search_relax} Greater than _{higher_priority_search} 。

Exemplary, T _{higher_priority_search_relax} And T _{higher_priority_search} Can satisfy the formula (1):

T _{higher_priority_search_relax} ＝N1*T _{higher_priority_search} (1)

wherein N1 is an integer greater than 1, i.e., T _{higher_priority_search_relax} Is T _{higher_priority_search} N1 times of (a). That is, if the terminal meets a certain trigger condition, the measurement interval adopted by the terminal in the RRM relaxation measurement scene for RRM measurement of the high priority frequency point is N1 times of the measurement interval adopted by the terminal not in the RRM relaxation measurement scene. The terminal in the RRM relaxation measurement scene carries out relaxation measurement aiming at the high-priority frequency points, so that the energy consumption of the terminal can be further saved.

Yet another exemplary, T _{higher_priority_search_relax} And T _{higher_priority_search} Can satisfy the formula (2):

T _{higher_priority_search_relax} ＝T _{higher_priority_search} +T1 (2)

wherein T1 can be understood as an adjustment factor, i.e. by adjusting T _{higher_priority_search} Obtaining T _{higher_priority_search_relax} . T1 may be located at [0,24 hours ]]The accuracy of T1 may reach the ms level, i.e. when a terminal in RRM relaxed measurement scenario is for high priority frequencies if a certain trigger condition is metThe measurement interval adopted by the point for RRM measurement is more than T1 than the measurement interval adopted when the point is not in the RRM relaxation measurement scene, so that the energy consumption of the terminal can be further saved.

Similarly, in the following, in the case where the trigger condition two will be satisfied, the measurement interval (e.g., the second preset measurement interval in table 4) adopted by the terminal for RRM measurement for the high priority frequency point uniformly adopts T _{measure,NR_Inte} In contrast, the measurement interval (e.g., the second target measurement interval in Table 4) used for RRM relaxation measurement of high priority frequency points is represented by T _{measure,NR_Inter_higher_priority_relax} Schematic representation. It is to be understood that T _{measure,NR_Inter_higher_priority_relax} Greater than T _{measure,NR_Inte} 。

Exemplary, T _{measure,NR_Inter_higher_priority_relax} And T _{measure,NR_Inte} Either equation (3) or equation (4) may be satisfied:

T _{measure,NR_Inter_higher_priority_relax} ＝1/N2*T _{measure,NR_Inte} (3)

T _{measure,NR_Inter_higher_priority_relax} ＝T _{measure,NR_Inte} +T2 (4)

wherein N2 is an integer less than 1, and T2 is greater than 0. When the trigger condition II is met, the terminal is in a measurement relaxation scene, and RRM relaxation measurement can be executed on the high-priority frequency point by the terminal, so that the energy consumption of the terminal is saved.

In the case that trigger condition two is satisfied, it is to be appreciated that the third target measurement interval may be greater than T _{measure,NR_Inter_higher_priority_relax} To ensure the quality of service as much as possible. Alternatively, the third target measurement interval may be less than T _{measure,NR_Inter_higher_priority_relax} To preferentially satisfy cell coverage.

The first target measurement interval may be the same as or different from the second target measurement interval. The values of N1, T1, N2, and T2 may be configured by the base station for the terminal, or may be fixed values specified by a protocol, or predetermined values by both the base station and the terminal, which is not limited in the embodiment of the present application.

Alternatively, the values of N1, T1, N2 and T2 may be determined by the terminal according to the intensity of the currently measured signal. For example, the strength of the currently measured signal is strong, the terminal may not need to reselect the cell, N1 may be increased, and T1 may also be increased; the strength of the current measured signal is poor, the terminal needs to reselect the cell, N1 can be reduced, and T1 can also be reduced.

As described above, the terminal in any RRM relaxation measurement scenario performs an RRM relaxation measurement policy that may be adopted by RRM measurement for each priority frequency point when the foregoing trigger condition one to trigger condition three are satisfied. And in the above table 4, only the RRM relaxation measurement strategies corresponding to the same priority frequency point under the same trigger condition in different RRM relaxation measurement scenes are taken as an example. In other embodiments, under the same trigger condition, in different RRM relaxation measurement scenarios, the target relaxation measurement strategies corresponding to the same priority frequency point may also be different.

Referring to table 5, a corresponding relationship between RRM relaxation measurement strategy and RRM relaxation measurement scenario and trigger condition is illustrated. The target relaxation measurement strategies corresponding to the same priority frequency point under the same trigger condition can be different in different RRM measurement relaxation scenarios (table 5 exemplifies this).

TABLE 5

The terminal is in a measurement relaxation scene I (stationary or moving at a low speed), if the trigger condition I is met, the signal quality of the service cell and the signal quality of the neighbor cell are relatively stable, the signal quality of the service cell is relatively high, and the terminal can not need to perform cell reselection. Therefore, the terminal can perform RRM relaxation measurement on the high-priority frequency points, and does not perform RRM measurement on the same-priority frequency points or low-priority frequency points, so that the energy consumption of the terminal is saved as much as possible. For example, RRM measurements are performed at a fifth target measurement interval, it being understood that the fifth target measurement interval is greater than the first preset measurement interval in table 4. If the trigger condition II is met, although the signal quality of the serving cell is poor, the signal quality of the serving cell and the signal quality of the neighbor cell are relatively stable, so that the terminal can execute RRM relaxation measurement on the high-priority frequency point, the same-priority frequency point and the low-priority frequency point in order to save the energy consumption of the terminal. For example, the terminal will perform RRM relaxation measurements on high priority frequency points with eighth target measurements and RRM relaxation measurements on equal priority frequency points or low priority frequency points with ninth target measurement intervals. It should be understood that the eighth target measurement interval is greater than the second preset measurement interval in table 4 and the ninth target measurement interval is greater than the third preset measurement interval in table 4. And the fifth target measurement interval may be greater than or equal to the eighth target measurement interval.

Along the line using the example of Table 4 above, T _{higher_priority_search_relax} And T _{higher_priority_search} The following formula (5) or formula (6) may be satisfied

T _{higher_priority_search_relax} ＝N3*T _{higher_priority_search} (5)

T _{higher_priority_search_relax} ＝T _{higher_priority_search} +T3 (6)

It will be appreciated that N3 is different from N1 and T3 is different from T1.

T _{measure,NR_Inter_higher_priority_relax} And T _{measure,NR_Inte} Either equation (7) or equation (8) may be satisfied:

T _{measure,NR_Inter_higher_priority_relax} ＝1/N4*T _{measure,NR_Inte} (7)

T _{measure,NR_Inter_higher_priority_relax} ＝T _{measure,NR_Inte} +T4 (8)

it will be appreciated that N4 is different from N2 and T4 is different from T2.

The terminal is in a measurement relaxation scene II (the terminal is not at the edge of the cell), if the trigger condition I is met, the signal quality of the service cell is higher, stable and better service can be provided for the terminal, and the terminal can not need to reselect the cell. Therefore, the terminal can perform RRM relaxation measurement on the high-priority frequency points, and does not perform RRM measurement on the same-priority frequency points or low-priority frequency points, so that the energy consumption of the terminal is saved as much as possible. For example, RRM measurements are performed at a sixth target measurement interval, it being understood that the sixth target measurement interval is greater than the first preset measurement interval in table 4. If the trigger condition II is met, the signal quality of the service cell is not high enough, but the signal of the service cell is stable, so that the terminal can execute RRM relaxation measurement on the high-priority frequency point, the same-priority frequency point and the low-priority frequency point in order to save the energy consumption of the terminal. For example, the terminal will perform RRM relaxation measurements on high priority frequency points using the tenth target measurement and RRM relaxation measurements on equal priority frequency points or low priority frequency points using the eleventh target measurement interval. It should be understood that the tenth target measurement interval is greater than the second preset measurement interval in table 4 and the eleventh target measurement interval is greater than the third preset measurement interval in table 4. And the sixth target measurement interval may be greater than or equal to the tenth target measurement interval. In some embodiments, the sixth target measurement interval is less than the fifth target measurement interval.

I.e. T _{higher_priority_search_relax} And T _{higher_priority_search} The following formula (9) or formula (10) may be satisfied

T _{higher_priority_search_relax} ＝N5*T _{higher_priority_search} (9)

T _{higher_priority_search_relax} ＝T _{higher_priority_search} +T5 (10)

It will be appreciated that N5 is different from N1, N3, and T5 is different from T1, T3.

T _{measure,NR_Inter_higher_priority_relax} And T _{measure,NR_Inte} Either equation (11) or equation (12) may be satisfied:

T _{measure,NR_Inter_higher_priority_relax} ＝1/N6*T _{measure,NR_Inte} (11)

T _{measure,NR_Inter_higher_priority_relax} ＝T _{measure,NR_Inte} +T6 (12)

it will be appreciated that N6 is different from N2, N4, and T6 is different from T2, T4. N5 is less than or equal to N3 and T6 is less than or equal to T4.

The terminal is in a measurement relaxation scene III (the terminal is not at the edge of the cell and the terminal moves at a low speed or is stationary), if the first trigger condition is met, the signal quality of the service cell is higher, the signal quality of the service cell is relatively stable, stable and better service can be provided for the terminal, and the terminal can not need to reselect the cell. Therefore, the terminal can perform RRM relaxation measurement on the high-priority frequency points, and does not perform RRM measurement on the same-priority frequency points or low-priority frequency points, so that the energy consumption of the terminal is saved as much as possible. For example, RRM measurements are performed at a seventh target measurement interval, it being understood that the seventh target measurement interval is greater than the first preset measurement interval in table 4. If the trigger condition II is met, the signal quality of the service cell is not high enough, but the signal of the service cell is stable, so that the terminal can execute RRM relaxation measurement on the high-priority frequency point, the same-priority frequency point and the low-priority frequency point in order to save the energy consumption of the terminal. For example, the terminal will perform RRM relaxation measurements on high priority frequency points using the twelfth target measurement and RRM relaxation measurements on equal priority frequency points or low priority frequency points using the thirteenth target measurement interval. It should be appreciated that the twelfth target measurement interval is greater than the second preset measurement interval in table 4 and the thirteenth target measurement interval is greater than the third preset measurement interval in table 4. And the seventh target measurement interval may be greater than or equal to the twelfth target measurement interval. In some embodiments, the seventh target measurement interval is greater than or equal to the sixth target measurement interval. The seventh target measurement interval is less than or equal to the fifth target measurement interval.

I.e. T _{higher_priority_search_relax} And T _{higher_priority_search} The following equation (13) or equation (14) may be satisfied

T _{higher_priority_search_relax} ＝N7*T _{higher_priority_search} (13)

T _{higher_priority_search_relax} ＝T _{higher_priority_search} +T7 (14)

It will be appreciated that N7 is different from N1, N3, N5, and T7 is different from T1, T3, T5.

T _{measure,NR_Inter_higher_priority_relax} And T _{measure,NR_Inte} Either equation (15) or equation (16) may be satisfied:

T _{measure,NR_Inter_higher_priority_relax} ＝1/N8*T _{measure,NR_Inte} (15)

T _{measure,NR_Inter_higher_priority_relax} ＝T _{measure,NR_Inte} +T8 (16)

it will be appreciated that N8 is different from N2, N4, N6, and T8 is different from T2, T4, T6. N7 is less than or equal to N5 and T8 is less than or equal to T6. For example, please refer to table 5, which is the relationship between the signal strength and the target measurement interval.

In some embodiments, to achieve better load gain, the terminal may perform a relaxation measurement on the high priority data. For example, for data that needs to be acquired periodically, the period of acquiring the data may be increased. In other words, the measurement interval adopted by the terminal to measure the high priority data is smaller than the measurement interval adopted by the terminal to measure the low priority data or the equivalent priority data. It should be understood that high priority data refers to data transmitted at a high priority frequency point, and similarly, low priority data refers to data transmitted at a low priority frequency point.

It should be appreciated that in any RRM relaxation measurement scenario, RRM relaxation measurements may also be performed for high priority frequency bins to further reduce the power consumption of the terminal. In some embodiments, the terminal may default to performing RRM relaxation measurement on the high priority frequency point in the RRM relaxation measurement scenario, so as to save energy consumption of the terminal as much as possible. In other embodiments, the base station may instruct the terminal whether to perform RRM relaxation measurements on the high priority frequency points to compromise the power consumption requirements and the communication performance requirements of the terminal.

S503, the base station sends indication information to the terminal, and the terminal receives the indication information, wherein the indication information is used for indicating whether the terminal executes RRM relaxation measurement on the high-priority frequency point. It should be appreciated that S503 is an optional step and is therefore illustrated in dashed lines in fig. 5.

The indication information can directly indicate the terminal to execute RRM relaxation measurement on the high-priority frequency point, or indirectly indicate the terminal to execute RRM relaxation measurement on the high-priority frequency point. Since the embodiment of the present application is directed to whether a terminal in a relaxation measurement scenario performs RRM relaxation measurement on a high priority frequency point, the indication information herein may also be understood as indicating whether a terminal in a relaxation measurement scenario performs RRM relaxation measurement on a high priority frequency point. Several possible implementations of the indication information are described below.

The direct indication mode may be m-bit information, where m-bit is a first value, and indicates the terminal to perform RRM relaxation measurement on the high-priority frequency point, and m-bit is a second value, and indicates the terminal to perform RRM relaxation measurement on the high-priority frequency point.

In a certain RRM relaxation measurement scenario, if the terminal receives the indication information, the indication information takes the second value, that is, indicates that the terminal does not perform RRM relaxation measurement on the high-priority frequency point, the terminal may determine, according to table 2, a target relaxation measurement policy corresponding to the RRM relaxation measurement scenario in which the terminal is located, and perform RRM measurement. And if the value of the indication information is a first value, indicating the terminal to perform RRM relaxation measurement on the high-priority frequency point. The terminal may determine the target relaxation measurement strategy to be employed for RRM measurements according to table 4.

The indication information may be carried in radio resource control (radio resource control, RRC) signaling or in a system message (system information, SI), i.e. the network device may broadcast the SI carrying the indication information, and send the indication information to the terminal. For example, the indication information may be carried in system message block 2 (system information block, sib 2). Wherein the indication information may carry cells defined in SIB2, such as cell reselection information (cellreselection) cells in SIB2, or other possible cells; alternatively, the indication information may also be carried in a cell newly defined in SIB2, and the embodiment of the present application does not limit the carrying manner of the indication information.

In the indirect indication mode, if the terminal receives the indication information, the terminal can be considered to perform RRM relaxation measurement on the high-priority frequency point, and conversely, if the terminal does not receive the indication information within a preset time period, the terminal can be considered to not perform RRM relaxation measurement on the high-priority frequency point.

In the embodiment of the application, the network side device can indicate, through the indication information, whether the terminal in the RRM relaxation measurement scene performs RRM relaxation measurement on the high-priority frequency point, so as to consider energy consumption, communication performance and load balancing of the terminal. It should be understood that the terminal may perform cell reselection after measuring the cell, i.e., after the terminal measures the frequency points with higher priority, lower priority, or equal priority.

For example, the indication information may be 1 bit information, the indication information carried in SIB2 is represented by highprioritymeasrelay, there may be highprioritymeasrelay=true, and the terminal is instructed to perform RRM relaxation measurement on the high priority frequency point; if highpriortymeasrelay=false, the terminal is instructed not to perform RRM relaxation measurements on high priority bins. If the terminal in measurement relaxation scenario one (Low mobility criterion) receives the indication information, determines that highprioritymeasrelay=true, the terminal can use the target measurement intervals (e.g., first target measurement interval, hereinafter T _{higher_priority_search_low_mobility} Representation) performs RRM relaxation measurements on high priority bins. I.e. T _{higher_priority_search_low_mobility} Greater than or equal to T _{higher_priority_search} 。

Similarly, if the terminal in measurement relaxation scenario two (Not at celledge criterion) receives the indication information, it determines that highprioritymeasrelay=true, and the terminal can adopt T _{higher_priority_search_low_mobility} RRM relaxation measurements are performed on high priority bins. Wherein T is _{higher_priority_search_low_mobility} Greater than or equal to the preset measurement interval corresponding to Table 4 and Table 5, i.e., T _{higher_priority_search} 。

If the terminal in measurement relaxation scenario three (Both low mobility criterion and not in celledge criterion) receives the indication information, it is determined that highprioritymeasrelay=true, and the terminal may employ T or more _{higher_priority_search} T of (2) _{higher_priority_search_low_mobility} For high priorityThe stage bins perform RRM relaxation measurements. It is to be understood that T _{higher_priority_search} The preset measurement intervals corresponding to table 4 and table 5 may be corresponded.

It should be appreciated that for high priority bins, there is a measurement interval versus measurement relaxation scenario shown in table 6.

TABLE 6

How the terminal performs RRM relaxation measurements for high priority frequency points is described above separately. It should be understood that the terminal may perform cell reselection after measuring the cell, i.e., after the terminal measures the frequency points with higher priority, lower priority, or equal priority.

Specifically, the base station managing each cell may set the priority of the frequency point where the cell is located according to the quality of service and other conditions that the base station can provide. The value range of the priority (cellreselection priority) of the cells on the frequency points is (0-7), and the larger the value is, the higher the priority of the frequency points is, and the higher the reselection priority of all the cells on the corresponding frequency points is. In the NR system, the base station may further configure a cell reselection sub-priority parameter (cellreselection sub-priority) for each carrier, where the value of cellreselection sub-priority may be 0.2/0.4/0.6/0.8.

The base station managing the cell may broadcast measurement configuration information of the cell through a system message (e.g., SIB 2) for the terminal accessing the cell to perform RRM measurement.

Please refer to table 7, which is a schematic table of possible parameters included in the measurement configuration information.

TABLE 7

As shown in table 7, the measurement configuration information includes the priority (cell reselection priority) of the frequency point of the cell, and signal quality parameters such as the frequency measurement threshold (S _intrasearch ) And an inter-frequency/inter-system measurement threshold (S _{nonintrasearch} ). It should be noted that, when the signal quality is represented by a signal quality parameter in the communication system, the above common-frequency measurement threshold and different-frequency/different-system measurement threshold are also 1; when represented by a plurality of signal quality parameters in a communication system, the above thresholds also correspond to a plurality. It will be appreciated that S in Table 7 _rxlev And S is _qual Is measured and calculated by the terminal and is not transmitted by the base station. Thus in Table 7, S _rxlev And S is _qual The corresponding system message is null.

Exemplary, the code of SIB2 carrying part of the measurement configuration information is as follows:

/>

the terminal receives the SIB2, if the terminal measures that the signal quality of the service cell meets the S of the service cell _rxlev Greater than S _intrasearch P, and S of the serving cell _qual Greater than S _intrasearch At Q, the terminal starts to perform measurement on the neighbor cell on the serving frequency point (frequency point where the serving cell is located). The terminal measures that the signal quality of the service cell satisfies the S of the service cell _rxlev Greater than S _{nonintrasearch} P, and S of the serving cell _qual Greater than S _{nonintrasearch} When Q, the terminal performs measurement on the neighbor cells on the high-priority frequency points; and when the signal quality of the serving cell measured by the terminal does not meet the condition, the terminal performs measurement on the adjacent cells on the high-priority target frequency point, the equal-priority target frequency point and the low-priority frequency point.

Similarly, when the terminal is in a relaxation measurement scenario, a relaxation reselection may be performed on the cell after performing a relaxation measurement on the target frequency point. That is, when the terminal determines that the cell reselection parameter of the target cell is greater than a first preset threshold, the terminal switches to the target cell, where the first preset threshold is greater than a second preset threshold, and the second preset threshold is a cell reselection threshold when the terminal is not in the transmission measurement scene. In other words, the cell reselection threshold is relaxed, and the first preset threshold is a threshold corresponding to a measurement relaxed scenario. The cell reselection parameter may be one or more of a cell reselection signal amplitude threshold (ThreshX, highP), a cell reselection signal strength threshold (ThreshX, highQ), and a cell reselection time interval threshold.

For example, the cell reselection parameter comprises a signal quality parameter of the cell, and the first preset threshold comprises a first signal quality threshold, e.g. ThreshX, highP and/or ThreshX, highQ. The cell reselection parameter comprises a cell reselection time interval and the first preset threshold comprises a first time threshold.

In a possible implementation manner, the determining, by the terminal, that the cell reselection parameter of the target cell is greater than the first preset threshold may include one or more of determining, by the terminal, that the signal quality of the target cell is greater than the first signal quality threshold, determining, by the terminal, that the duration of time that the signal quality of the target cell is greater than the second signal quality threshold exceeds the first time threshold, the second signal quality threshold being different from the first signal quality threshold, and determining, by the terminal, that the duration of time that the signal quality of the target cell is greater than the first signal quality threshold exceeds the first time threshold.

In some embodiments, after the terminal detects the high priority cell, when the signal quality of the target cell (i.e. the cell reselected by the terminal) is high (S _qual ) Above ThreshX, highQ, beyond treselection rat, the terminal performs cell reselection. Or if the signal amplitude of the target cell is greater than ThreshX, highP, in treselection rat, the terminal has network drop of more than 1s in the current service cell, and the terminal performs cell reselection.

However, when the terminal in the measurement relaxation scenario meets that the signal amplitude of the target cell is greater than ThreshX and HighP and the signal strength of the target cell is greater than ThreshX and HighQ, the signal quality of the pre-serving cell is better, so that the frequent cell reselection can be reduced in order to save signaling overhead and energy consumption. To this end, in embodiments of the present application, the threshold for cell reselection may be raised, for example, by relaxing one or more of ThreshX, highP, threshX, highQ, cell reselection time interval. I.e. increasing ThreshXHighQ, hereinafter the cell handover threshold applicable for the relaxation measurement is referred to as the relaxation handover threshold, indicated by threshxhigq_relay, it being understood that threshxhigq_relay is larger than ThreshX, highQ. Similarly, the embodiment of the present application may increase the treselection rat to be suitable for cell reselection of the relaxation measurement, and hereinafter, the cell reselection time interval suitable for the relaxation measurement is referred to as a cell reselection relaxation time interval, which is indicated by treselection rat_relay.

In a possible implementation manner, in the treselection rat, when the signal strength of the target cell is greater than threshxhigq_relay, the terminal may perform cell reselection according to threshxhigq_relay and treselection rat; or in treselection rat_relay, when the signal intensity of the target cell is greater than ThreshX, highQ, the terminal can perform cell reselection according to ThreshX, highQ and treselection rat_relay; or in treselection rat_relay, when the signal strength of the target cell is greater than ThreshX, highQ, and the terminal performs cell reselection according to threshxhigq_relay and treselection rat_relay, the embodiment of the present application is not limited.

In other embodiments, the terminal may reselect to a equally prioritized cell. For example, the terminal may rank the candidate cells according to the on-channel cell switching mechanism, i.e. the converted signal amplitude Rs and the converted signal quality Rn from high to low, and the terminal reselects to the highest ranked cell. Wherein Rs and Rn satisfy formulas (17) and (18), respectively:

Rs＝Qmeas,s+Qhyst-Qoffsettemp (17)

Rn＝Qmeas,n-Qoffset-Qoffsettemp (18)

wherein, qmeas s is the measured signal amplitude, qmeas, n is the measured signal quality of the corresponding frequency point, and qoffsetemp is the measured temporary adjustment value. Rn is the signal quality after conversion, qmeas, n is the signal quality of the corresponding frequency point, qhyst is the set signal amplitude threshold, qoffset is the measurement quality threshold. When a certain cell has better quality in the treselection rat and the terminal has network drop of more than 1s in the current service cell, the terminal can perform cell reselection. When no handover to the optimal cell (rangeToBestCell) is configured, i.e. the base station does not configure the target cell to be handed over for the terminal, the UE will reselect to the highest ranked cell. When configuring the rangeToBestCell, the terminal will switch to the cell having the most number of beams (beams) above the threshold, and if there are more than one beam cell, select the cell with the highest rank.

But the priority of the target cell is the same as the priority of the current serving cell of the terminal, so that the quality of service provided for the terminal may be the same, in which case the terminal may not perform cell reselection in order to save signaling and energy consumption. Therefore, in the embodiment of the present application, after performing the relaxed RRM measurement on the cells with the same priority, the terminal in the relaxed scenario may not perform cell reselection.

In other embodiments, for reselection of the lower priority cell, the terminal drops from the serving cell for more than 1s, when the signal strength of the serving cell is satisfied to be less than ThreshServing, lowQ, and the lower priority cell satisfies the signal strength to be greater than ThreshX in treselectionrat_relay, lowQ, the terminal may reselect for the lower priority cell. Or the signal amplitude of the current service cell is smaller than ThreshServing, lowP, the low priority cell satisfies that the signal amplitude value is larger than ThreshX and LowP in the treselection rat, and the terminal has network drop of more than 1s in the current service cell, and the terminal can reselect the cell with lower priority.

In some embodiments, in a certain relaxed measurement scenario, treselection rat_relay corresponding to different priority frequency points may be the same, and ThreshX, lowQ, and/or ThreshServing, lowP corresponding to different priority frequency points may be the same.

In other embodiments, in a certain relaxed measurement scenario, one or more of treselection rat_relay, threshX, lowQ, threshServing, lowP corresponding to different priority frequency points are different.

It should be appreciated that treselection rat_relay is greater than or equal to treselection rat upon which a terminal not in RRM relaxed measurement scenario performs cell reselection. ThreshX, lowQ in RRM relaxation measurement scenarios is greater than or equal to ThreshX, lowQ not in RRM relaxation measurement scenarios, and ThreshServing, lowP in RRM relaxation measurement scenarios is greater than or equal to ThreshServing, lowP not in RRM relaxation measurement scenarios.

According to the embodiment of the application, for the terminal in the relaxation measurement scene, a relaxation measurement strategy adopted by relaxation measurement of the target frequency point can be determined through a relaxation measurement threshold. The priority of the target frequency point may be higher than the priority of the frequency point of the serving cell, or may be lower than or equal to the priority of the frequency point of the serving cell, and the relaxation measurement threshold may be flexibly set for the target frequency points with different priorities, so as to consider the communication performance and the energy saving requirement of the terminal.

Further, the embodiment of the application can relax the cell reselection, namely improve the cell reselection threshold, so as to avoid frequent reselection of the cell by the terminal as much as possible.

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.

The units can be independently arranged or partially or fully integrated.

In some possible embodiments, the communications device 600 can correspondingly implement the behaviors and functions of the terminal in the above method embodiments. For example, the communication device 600 may be a terminal, or may be a component (e.g., a chip or a circuit) applied to the terminal.
