Technical field

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

Background technique

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

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 greater than the inter-frequency/different system measurement signal amplitude threshold, and the quality of the serving cell signal is greater than the inter-frequency/different system measurement signal strength threshold, the terminal searches for higher priority frequencies at least every second. Point of the cell. Conversely, if the signal amplitude of the serving cell is less than or equal to the inter-frequency/different system measurement signal amplitude threshold, or the signal quality of the serving cell is less than the inter-frequency/different system measurement signal strength threshold, the terminal will search and measure with higher priority and higher priority. Cells with low or equal frequency. After that, the terminal can perform cell reselection based on the measurement result. It should be understood that the inter-frequency/different system measurement signal amplitude threshold and the inter-frequency/different system measurement signal strength threshold are thresholds for cell measurement. The priority here refers to the priority of the frequency point, and a cell with a high priority frequency point is also called a high priority cell.

In order to reduce the power consumption of the terminal, the concept of RRM relaxation measurement (RRM relaxation) is currently proposed, that is, if the terminal is in the RRM relaxation measurement scenario, the terminal can perform RRM relaxation measurement. For example, the terminal can reduce the number of RRM measurements (for example, increase RRM measurement). Measurement interval). However, for terminals in the RRM relaxation measurement scenario, there is no further solution for how to perform relaxation measurement on high-priority frequency points.

Summary of the invention

The present application provides a relaxation measurement method and communication device, which are used to provide a relaxation measurement strategy based on the priority of the frequency point, so as to take into account the energy consumption demand of the terminal and the load gain demand.

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

The terminal determines the signal quality of the serving cell, and according to the signal quality of the serving cell and the relaxation measurement threshold, determines a target measurement strategy for measuring the target frequency point, and performs relaxation measurement on the target frequency point according to the target measurement strategy; wherein , The terminal is in the first relaxation measurement scenario, the relaxation measurement threshold is greater than the measurement access threshold, and the measurement access threshold is the threshold used by the terminal that is not in the first relaxation measurement scenario to perform measurement.

This solution is aimed at a terminal in a relaxed measurement scenario, and the measurement threshold can be relaxed to determine the relaxed measurement strategy adopted for the relaxed measurement of the target frequency point afterwards. The priority of the target frequency may be higher than the priority of the frequency of the serving cell, or may be lower than or equal to the priority of the frequency of the serving cell, and the relaxation measurement threshold can be flexibly set for target frequency of different priorities , In order to take into account the terminal's communication performance and energy-saving requirements.

In a possible implementation manner, the terminal determines that the signal quality of the serving cell is greater than the relaxation measurement threshold, and the terminal determines the target frequency point for measurement according to the signal quality of the serving cell and the relaxation measurement threshold. The target measurement strategy includes:

The terminal determines to perform measurement on the target frequency point according to the first value of the measurement interval, wherein the priority of the target frequency point is higher than the priority of the frequency point of the serving cell, and the first value Greater than the first initial value, the first initial value is the value of the measurement interval used by the terminal that is not in the relaxed measurement scenario to perform measurement on the target frequency point; or, the terminal determines to perform the measurement on the target frequency point; Point does not perform measurement, the priority of the target frequency point is the same as the priority of the frequency point of the serving cell, or the priority of the target frequency point is lower than the priority of the frequency point of the serving cell.

In this solution, if the signal quality of the serving cell is greater than the relaxation 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 relaxed measurement scenario, the terminal can perform a relaxed measurement on a target frequency point with a high priority, and does not perform a relaxed measurement on a target frequency point with the same or low priority, so as to further reduce the energy consumption of the terminal.

In a possible implementation manner, the terminal determines that the signal quality of the serving cell is less than or equal to the relaxation measurement threshold, and the terminal determines the measurement target according to the signal quality of the serving cell and the relaxation measurement threshold. Target measurement strategies for frequency points, including:

In this solution, if the terminal is in a relaxed measurement scenario, the signal quality of the serving cell is relatively stable. Although the signal quality of the serving cell is less 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 relatively stable, the terminal can also perform relaxation measurement on the target frequency points of each priority to minimize the terminal Energy consumption.

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

In a possible implementation manner, 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 first value The sum of two initial values and a second adjustment factor, the second adjustment factor is within a first preset range, and the second adjustment factor is greater than zero.

Since the first initial value and the second initial value are both known as the value of the measurement interval used by the terminal that is not in the relaxed measurement scenario to perform measurement on the target frequency point, that is, it has been defined by the existing protocol. Therefore, the first value is determined by the first initial value, and the second value is determined by the second initial value, which facilitates compatibility with existing protocols.

In a possible implementation manner, there are multiple relaxation measurement scenarios, wherein the first value or the second value corresponding to different relaxation measurement scenarios is the same; or, all relaxation measurement scenarios corresponding to different relaxation measurement scenarios are the same. The first value or the second value is different. In this solution, the first value or the second value corresponding to different relaxation measurement scenarios is the same, which is simpler. The first value or the second value corresponding to different relaxation measurement scenarios is different, which is more conducive to taking into account the requirements of communication performance and energy consumption of the terminal.

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

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

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

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

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

SFN mod T=FLOOR(gapOffset/10);

subframe=gapOffset mod 10;

T=MGRP/10;

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

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

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

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

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

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

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

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

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

Table 1-Schematic of measurement capability information

The network device can determine whether to configure the measurement gap for the terminal according to the measurement capability reported by the terminal, so that the terminal performs RRM measurement according to the configuration of the network device.

After the terminal performs RRM measurement on the neighboring cell on the target frequency point (including the same frequency frequency point and/or different frequency frequency point), it can reselect the cell to ensure the communication quality as much as possible. For example, after the terminal performs RRM measurement, it can switch to a high-priority cell. It should be noted that the priority here refers to the priority of the frequency and/or carrier. Cells on the same frequency and/or carrier on the same radio access technology (RAT) have the same priority. The cell priorities of different frequency points and/or carriers may be the same or different. A cell with a high priority frequency and/or carrier can be referred to as a high priority cell. Similarly, a cell with a low priority frequency and/or carrier can be referred to as a low priority cell. If two frequencies of the same level are separately Corresponding cells can be referred to simply as cells of equal priority.

According to the relative relationship between the priority of the target frequency point and the priority of the service frequency point (the frequency point where the serving cell is located), the target frequency point is divided into a high priority target frequency point, a target frequency point of the same priority and a low priority target Frequency. It should be understood that the high-priority target frequency point is a target frequency point whose priority is higher than the priority of the service frequency point. The same priority target frequency point, that is, the target frequency point with the same priority as the priority of the service frequency point. The low-priority target frequency point, that is, the target frequency point whose priority is lower than the priority of the service frequency point.

The network device defines the priority of each frequency point. For example, the network device can determine the priority of the frequency point according to the network coverage of a certain frequency point and/or the number of users under a certain frequency point. For example, the priority of 5G is higher than the priority of 4G, and the priority of 4G is higher than the priority of 3G. For another example, if the number of users under a certain frequency point is more than the number of users under another frequency point, then the priority of this frequency point is lower than the priority of another frequency point. The network device can inform the terminal of the priority of each frequency point. For example, the network device can broadcast the priority of each frequency point.

The terminal can perform cell reselection according to the priority of the frequency point. For example, the terminal may switch from a frequency cell with a large number of users to a frequency cell with a small number of users to meet the demand for load balancing. For another example, the operator can specify that the terminal uses the 5G network by default, and the network device can set the priority of the 5G network to the highest priority.

Before the terminal performs cell reselection, it can perform RRM measurements on the serving frequency and the adjacent cell frequency. In some embodiments, a corresponding RRM measurement trigger condition is set for each priority frequency point, and the terminal measures the priority frequency point corresponding to the trigger condition after determining that a certain trigger condition is satisfied. For example, the trigger condition set for high-priority frequency points 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. That is, to meet the trigger condition set by the high priority frequency point, the terminal performs RRM measurement on the high priority frequency point, and does not measure the low priority frequency point or the frequency point of the same priority.

Since the terminal in the RRC_idle state and the RRC_inactive state periodically performs RRM measurement, it can be considered as the main source of power consumption of the terminal. However, in some measurement scenarios, such as when the terminal is in a stationary state or the moving speed of the terminal is low, it is not necessary to perform RRM measurements frequently. Therefore, in order to reduce the power consumption of the terminal, the concept of RRM relaxation measurement is currently proposed. That is, the terminal is in a certain relaxation measurement scenario, and the terminal can perform RRM relaxation measurement. For example, the terminal may reduce the number of RRM measurements (for example, increase the time interval of RRM measurement), and for example, the terminal may reduce the measurement objects (for example, the terminal may reduce the number of target frequency points to be measured, or the terminal may reduce the number of neighboring cells to be measured).

When the terminal is in a relaxed measurement scenario, such as the terminal is stationary or moving at a low speed, the signal quality of the serving cell and neighboring cells are relatively stable and will remain within a certain range for a long time. Therefore, the terminal can perform RRM loosening measurements on the serving cell and neighboring cells. In this case, if it is satisfied that 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. It can provide a stable and better service for the terminal. Therefore, the terminal does not need to be reselected to a neighboring cell. In order to save the energy consumption of the terminal, the RRM relaxation measurement can be further performed on the high-priority frequency points. However, for terminals in the RRM relaxation measurement scenario, there is no further solution for how to perform relaxation measurement on high-priority frequency points.

In view of this, the embodiments of the present application provide a relaxed measurement method. The solution is aimed at a terminal in a relaxed measurement scenario, and clarifies the method used by the terminal to measure high-priority frequency points (hereinafter, also referred to as high-priority cells). The relaxation measurement strategy (hereinafter, also referred to as the relaxation measurement strategy) is used to take into account the power consumption requirements of the terminal and the load balancing requirements.

In order to facilitate the understanding of those skilled in the art, before introducing the technical solutions provided by the embodiments of the present application, some terms in the embodiments of the present application will be explained below.

1) Signal quality, which is the RRM measurement performed by the terminal on the cell, and the measurement result obtained may include one or more of the following signal quality parameters:

Signal amplitude (Srxlev, _{represented by S rxlev in} this article), signal strength (Squal, _{represented by S qual in} this article), reference signal received power (RSRP), reference signal received quality (reference signal received quality, RSRQ), signal to noise ratio (SNR), signal to interference plus noise ratio (SINR), etc.

2) The measurement configuration information of the cell is used for the terminal equipment accessing the cell to perform RRM measurement. Wherein, the measurement configuration information includes the priority (cell reselection priority) and the measurement threshold (S _search ) of the frequency point where the cell is located. Wherein, the measurement threshold may include an intra-frequency measurement threshold (Sintrasearch, denoted by S _{intrasearch in} this document), and an inter-frequency/different system measurement threshold (Snonintrasearch, denoted by S _{nonintrasearch in} this document). The signal quality can be characterized by the signal amplitude. If the signal amplitude is greater than the same-frequency measurement threshold, the signal quality is good. Signal quality can also be characterized by signal strength. If the signal strength is greater than the inter-frequency/different system measurement threshold, the signal quality is better. Or signal quality can also be characterized by signal amplitude and signal strength. If the signal amplitude is greater than the same-frequency measurement threshold, and the signal strength is greater than the inter-frequency/different system measurement threshold, the signal quality is good.

Exemplarily, when the signal quality is expressed by the signal amplitude and the signal strength, the same frequency measurement threshold includes: the same frequency measurement signal amplitude threshold (SintrasearchP, denoted by S _intrasearch P herein) and the same frequency measurement signal strength threshold (SintrasearchQ, _{represented by S intrasearch} Q in this article). Among them, S _intrasearch P is used to indicate the signal amplitude threshold of the same frequency measurement, and S _intrasearch Q is used to indicate the signal strength threshold of the same frequency measurement. In the current measurement strategy, when the terminal device using the cell as the serving cell measures the signal quality of the cell to meet the following conditions, the terminal device starts to perform measurement on the neighboring cell on the serving frequency point (the frequency point where the serving cell is located) : The signal amplitude (S _rxlev ) in the signal quality of the cell is greater than the S _intrasearch _{P, and the signal strength (S qual} ) in the signal quality of the cell is greater than the S _intrasearch Q.

At the same time, the inter-frequency/inter-system measurement threshold includes: inter-frequency measurement signal amplitude threshold (SnonintrasearchP, denoted by S _{nonintrasearch P herein) and inter-} frequency measurement signal strength threshold (SnonintrasearchQ, denoted by S _{nonintrasearch} Q in this document). Among them, S _{nonintrasearch} P is used to indicate the signal amplitude threshold of inter-frequency/different system measurements (This specifies the Srxlev threshold (in dB) for NR inter-frequency and inter-RAT measurements), and S _{nonintrasearch} Q is used to indicate inter-frequency/inter-RAT measurements. The signal strength threshold measured by the different system (This specifies the Squal threshold (in dB) for NR inter-frequency and inter-RAT measurements). In the current measurement strategy, when the terminal equipment that uses the cell as the serving cell measures the signal quality of the cell to meet the following conditions, the terminal equipment performs measurement on the neighboring cell on the high-priority target frequency point: the signal of the cell The signal amplitude (S _rxlev ) in the quality is greater than the S _{nonintrasearch} P, and the signal strength (S _qual ) in the signal quality of the cell is greater than the S _{nonintrasearch} Q; when the signal quality of the cell measured by the terminal device does not meet the requirement When the conditions are met, the terminal device performs measurement on the neighboring cells on the high-priority target frequency point, the same-priority target frequency point, and the low-priority target frequency point.

3) Cell reselection threshold, the cell reselection threshold may include inter-frequency/different system high priority RSRP reselection threshold (in this article, ThreshX, HighP), and inter-frequency/different system high priority RSRQ reselection Threshold (denoted by ThreshX, HighQ in this article). ThreshX, HighP are used to indicate the signal amplitude threshold of different frequency/different system reselection, ThreshX, HighQ are used to indicate the signal strength threshold of different frequency/different 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 within the cell reselection time interval _{Target cell: the signal amplitude (S rxlev} ) in the signal quality of the target cell is greater than the hreshX, HighP; or, the signal strength (S _qual ) in the signal quality of the target cell is greater than the ThreshX, HighQ, and the terminal is currently serving The cell is disconnected for more than 1s, that is, the terminal cannot connect to the base station for at least 1s.

In the cell reselection threshold, the low priority RSRP threshold of the serving cell (ThreshServing, LowP in this article) and the low priority RSRQ threshold of the serving cell (ThreshServing, LowQ in this article) can be used. ThreshServing, LowP are used to indicate the signal amplitude threshold of the same frequency reselection, and ThreshServing, LowQ are used to indicate the signal strength threshold of the same frequency reselection. In the current cell reselection process, for the reselection of the cell with the same priority frequency point, when the terminal measures that the signal quality of the target cell meets the following conditions, the terminal is disconnected from the serving cell for more than 1 second. The signal strength is less than ThreshServing, LowQ, and the target cell meets the signal strength greater than ThreshX, LowQ in TreselectionRAT_relax; or, the signal amplitude of the current serving cell is less than ThreshServing, LowP, and the target cell meets the signal amplitude value greater than ThreshX, LowP in TreselectionRAT , And the terminal has been disconnected for more than 1s in the current serving cell.

4) Cell reselection time interval, (represented by TreselectionRAT in this article), the time threshold for the terminal to reselect the target cell. That is, within the cell reselection time interval, the signal amplitude (S _rxlev ) in the signal quality of the target cell is greater than the hreshX, HighP, and exceeds the cell reselection time interval, and the terminal reselects the target cell. Alternatively, within the cell reselection time interval, the signal strength (S _qual ) of the signal quality of the target cell is greater than the ThreshX, HighQ, and the terminal is offline for more than 1 s in the current serving cell, and the terminal reselects the target cell.

In addition, the technical solutions provided in the embodiments of the present application can be used for RRM measurement, and can also be used for RLM. It should be understood that when the technical solution is used for RRM measurement, the relaxation measurement method provided in the embodiment of this application can also be referred to as the RRM relaxation measurement method; when the technical solution is used for RLM measurement, then the relaxation measurement method provided in the embodiment of the application is It can also be called RLM relaxation measurement method. In the case of no conflict, the RRM in the embodiments of the present application can be replaced with RLM. The following takes the application of this technical solution to RRM measurement as an example.

The following describes the technical solutions provided by the embodiments of the present application in conjunction with the accompanying drawings.

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

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

S501: The terminal determines the signal quality of the serving cell, where the terminal is in the first RRM relaxation measurement scenario;

S502: The terminal determines the target relaxation measurement strategy of each priority frequency point according to the signal quality of the serving cell and the relaxation measurement threshold, and executes the RRM relaxation measurement according to the target relaxation measurement strategy.

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

The embodiments of the present application aim to set a corresponding RRM relaxation measurement strategy for each priority frequency point for a terminal in an RRM relaxation measurement scenario. It should be understood that the RRM relaxation measurement scenario is a scenario suitable for the terminal to perform RRM relaxation measurement. In other words, when the terminal satisfies a certain measurement scenario among these measurement scenarios, the terminal can perform RRM relaxation measurement. Several possible RRM relaxation measurement scenarios are listed below. See Table 2, which illustrates three relaxation measurement scenarios and corresponding relaxation measurement strategies.

Table 2

As shown in Table 2, measure relaxation scenario 1. The terminal is stationary or moving at a low speed. In this scenario, the signal quality of the serving cell of the terminal does not change beyond the set threshold 1. The signal quality of the serving cell and neighboring cells are relatively stable and will remain within a certain range for a long time, so the terminal can perform RRM relaxation on the serving cell Measurement, you can also perform RRM relaxation measurement on the neighboring area.

Measurement relaxation scenario 2: The terminal device 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, which can provide the terminal with stable and better service. Therefore, the terminal does not need to reselect to the neighboring cell and can The neighboring cell performs RRM relaxation measurement.

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

It should be understood that the first measurement interval and the second measurement interval in Table 2 are both larger than the measurement interval corresponding to the scenario where the terminal is not in the RRM measurement relaxation scenario. Among them, in Table 2, Strategy 1 and Strategy 2 may be the same, for example, the first measurement interval and the second measurement interval are the same. Or in Table 2, Strategy 1 and Strategy 2 may also be different, for example, the first measurement interval and the second measurement interval are different; or, the first measurement interval and the second measurement interval are the same, but the number of neighboring cells measured by Strategy 1 is the same as The number of neighboring cells measured by strategy 2 is different and so on. It should be noted that Table 2 only illustrates the RRM measurement strategy with a measurement interval, that is, one measurement parameter. In specific implementation, the RRM measurement strategy may include multiple measurement parameters.

During the RRM measurement process, the terminal can measure the neighboring cells on the low-priority target frequency point and the target frequency point of the same priority to meet the needs of cell coverage. The terminal measures the neighboring cells on the high-priority target frequency point in order to be able to obtain better services. When a trigger condition corresponding to a certain priority frequency point is met, the terminal measures the priority frequency point. In order to take into account the cell coverage problem and the service quality problem of the terminal equipment, the trigger conditions for the terminal equipment to measure the neighboring cells of different priority target frequency points are also different. Exemplarily, please refer to Table 3 for the relationship between the trigger condition and the RRM measurement object.

table 3

It should be understood that, when a certain trigger condition is met, the terminal performs RRM measurement on the RRM measurement object corresponding to the trigger condition according to a preset measurement interval. For example, usually when the terminal determines that the signal quality of the serving cell is greater than the inter-frequency/different system measurement threshold, only the neighboring cell on the high-priority target frequency point is measured; when the terminal equipment determines that the signal quality is not greater than the inter-frequency/different system measurement threshold In a limited time, measure the neighboring cells at the high priority target frequency point, the same 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 scenario, the relaxation measurement can be further performed on each priority frequency point. The following describes the relaxation measurement strategy (hereinafter referred to as the target relaxation measurement strategy) that can be adopted by the terminal for each priority frequency point in each RRM measurement relaxation scenario. In the following description, taking the signal amplitude and signal strength as an example, the trigger condition 1 in Table 3 can be understood as the S _{rxlev of the serving cell is greater than the inter-} frequency/inter-system measurement signal amplitude threshold S _{nonintrasearch} P, and the S _{qual of the} _{serving cell is greater than the inter-} frequency/inter-system measurement signal strength threshold S nonintrasearch Q. The second trigger condition can be that S _{rxlev is} less than or equal to S _{nonintrasearch} P, or Squal is less than or equal to S _{nonintrasearch} Q.

For example, if the terminal is in a static or low-speed moving scene (measurement relaxation scene 1), S _{rxlev is} greater than S _{nonintrasearch} P, and S _{qual is} greater than S _{nonintrasearch} Q. In this case, the signal quality of the serving cell is relatively high, and the signal quality of the serving cell and the neighboring cell are relatively stable, and the terminal may not need to reselect to the neighboring cell. Therefore, in order to reduce the energy consumption of the terminal, you can further perform RRM relaxation measurement on high-priority frequency points, that is, perform RRM measurement on high-priority frequency points at a measurement interval that is longer than the measurement interval used when not in a relaxed measurement scenario. , RRM measurement is not performed on low-priority frequency points or frequency points of the same priority. That is, the terminal in the relaxed measurement scenario performs RRM measurement on the high-priority frequency points at a measurement interval that is longer than the measurement interval used when the terminal is not in the relaxed measurement scenario.

Or, the terminal is in the measurement relaxation scenario 1, S _{rxlev is} less than or equal to S _{nonintrasearch} P, and S _{qual is} less than or equal to S _{nonintrasearch} Q. It can be considered that the quality of the serving cell is poor. In order to obtain a stable and better service, the terminal can be reselected to a neighboring cell. Therefore, the terminal will search for and measure the frequency points with higher, lower or equal priority, that is, the terminal can perform RRM measurement on the neighboring cell. In this case, since the terminal is in measurement relaxation scenario 1, the signal quality of the serving cell is relatively stable. In order to reduce the power consumption of the terminal, the terminal can also perform RRM relaxation measurement on the neighboring cell. For example, for high-priority frequency points, the RRM measurement is performed at a measurement interval that is longer than the measurement interval used when the measurement is not in a relaxation scenario. For another example, for frequency points with the same priority and low priority frequency points, the RRM measurement can also be performed at a measurement interval longer than the measurement interval used when the measurement is not in a relaxation scenario. It should be understood that the measurement interval used for the RRM measurement of high-priority frequency points is smaller than the measurement interval used for the RRM measurement of the same priority frequency points and low-priority frequency points. The measurement interval used for the RRM measurement at the same priority frequency point and the low priority frequency point may be the same or different.

In any RRM measurement relaxation scenario, the terminal can satisfy trigger condition one or trigger condition two, that is, in any RRM measurement relaxation scenario, the terminal can further perform relaxation measurement on each priority frequency point. The following describes the relaxation measurement strategy (hereinafter referred to as the target relaxation measurement strategy) that can be adopted by the terminal for each priority frequency point in each RRM measurement relaxation scenario.

Exemplarily, please refer to Table 4, which is the target relaxation measurement strategy for each high-priority frequency point corresponding to each high-priority frequency point under different trigger conditions in the first RRM measurement relaxation scenario. The first RRM measurement relaxation scene is any one of the three measurement relaxation scenes shown in Table 2. That is, the RRM relaxation measurement strategy shown in Table 4 has nothing to do with which RRM relaxation measurement scenario, that is, in different RRM measurement relaxation scenarios, under the same trigger condition, the target relaxation measurement strategy corresponding to the same priority frequency point is the same.

Table 4

Among them, the first target measurement interval in Table 4 is greater than the first preset measurement interval. Here, the number of high-priority measurements can be reduced and the energy consumption of the terminal can be saved. Similarly, the second target measurement interval is greater than the second preset measurement interval, and the third target measurement interval is greater than the third preset measurement interval, so as to save energy consumption of the terminal. It should be understood that the first preset measurement interval, the second preset measurement interval, and the third preset measurement interval may be the initial value of the preset measurement interval. Among them, the preset measurement interval corresponding to the frequency point of the same priority and the preset measurement interval corresponding to the frequency point of the low priority may be different or the same (Table 4 takes this as an example, and both are the third preset measurement interval). Similarly, the target measurement interval corresponding to the same priority frequency point and the target measurement interval corresponding to the low priority frequency point may be different or the same (Table 4 takes this as an example, both are the third target measurement interval).

In some embodiments, the measurement interval used by the terminal to perform RRM measurement on high-priority frequency points, equal-priority frequency points, or low-priority frequency points respectively under each trigger condition is predefined (as shown in the first The preset measurement interval to the third preset measurement interval). That is, the search period for the terminal to search for each priority frequency point can be predefined. Of course, the first preset measurement interval to the third preset measurement interval may also be agreed in advance by the terminal and the network device, or the network device may be configured for the terminal, which is not limited in the embodiment of the present application. It should be understood that the first preset measurement interval to the third preset measurement interval are the corresponding measurement access thresholds, that is, the thresholds used by the terminal that is not in the relaxed measurement scenario to perform measurement.

The following describes 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 under different trigger conditions.

For ease of description, in the following, when trigger condition one is met, the measurement interval used by the terminal to perform RRM measurement for high-priority frequency points (such as the first preset measurement interval in Table 4) is uniformly represented _{by Higher_priority_search.} Relatively speaking, the measurement interval (for example, the first target measurement interval in Table 4) used for the RRM relaxation measurement of the high-priority frequency points is indicated _{by T higher_priority_search_relax.} It should be understood that T _{higher_priority_search_relax is} greater than _{higher_priority_search} .

Exemplarily, T _{higher_priority_search_relax} and T _{higher_priority_search} can satisfy 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 _T higher_priority_search of times is N1. That is, if the terminal meets a certain trigger condition, the measurement interval used by the terminal in the RRM relaxation measurement scenario for the high priority frequency point to perform RRM measurement is N1 times the measurement interval used when the terminal is not in the RRM relaxation measurement scenario . That is, the terminal in the RRM relaxation measurement scenario performs relaxation measurement for high-priority frequency points, which can further save the energy consumption of the terminal.

As another example, T _{higher_priority_search_relax} and T _{higher_priority_search} can satisfy formula (2):

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

Among them, T1 can be understood as an adjustment factor, that is, T _{higher_priority_search_relax is} obtained _{by adjusting T higher_priority_search} . T1 can be located in [0,24 hours], and the accuracy of T1 can reach the ms level, that is, if a certain trigger condition is met, the measurement used by the terminal in the RRM relaxation measurement scenario for the high priority frequency point to perform RRM measurement The interval is T1 longer than the measurement interval used when the RRM is not in the relaxed measurement scenario, which can also further save the energy consumption of the terminal.

In the same way, in the following, when triggering condition two is met, the measurement interval used by the terminal for RRM measurement on high priority frequency points (such as the second preset measurement interval in Table 4) is uniformly T _measure, represented by NR_Inte Relatively speaking, the measurement interval (for example, the second target measurement interval in Table 4) used for the RRM relaxation measurement of the high-priority frequency points is indicated _{by T measure,NR_Inter_higher_priority_relax.} It should be understood that T _{measure,NR_Inter_higher_priority_relax is} greater than T _{measure,NR_Inte} .

Exemplarily, T _{measure, NR_Inter_higher_priority_relax} and T _{measure, NR_Inte} can satisfy formula (3) or formula (4):

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)

Among them, N2 is an integer less than 1, and T2 is greater than zero. When the second trigger condition is met and the terminal is in a measurement relaxation scenario, the terminal can perform RRM relaxation measurement on high-priority frequency points to save energy consumption of the terminal.

In the case of satisfying the second trigger condition, it should be understood 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 _Tmeasure ,NR_Inter_higher_priority_relax, so as to preferentially satisfy the cell coverage.

It should be noted that the first target measurement interval and the second target measurement interval may be the same or different. The values of N1, T1, N2, and T2 may be configured by the base station for the terminal, or may be fixed values specified in the agreement, or predetermined values by both the base station or the terminal, which are not limited in the embodiment of the present application.

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

As described above, the RRM relaxation measurement strategy that may be adopted by the terminal in any RRM relaxation measurement scenario to perform RRM measurement for each priority frequency point under the condition that the aforementioned trigger condition 1 to trigger condition 3 is satisfied. In addition, as shown in Table 4 above, only under different RRM relaxation measurement scenarios, under the same trigger condition, the RRM relaxation measurement strategy corresponding to the same priority frequency point is the same as an example. In other embodiments, under the same trigger condition and in different RRM relaxation measurement scenarios, the target relaxation measurement strategies corresponding to the same priority frequency point may also be different.

Please refer to Table 5, which illustrates the correspondence between an RRM relaxation measurement strategy and RRM relaxation measurement scenarios and trigger conditions. Under different RRM measurement relaxation scenarios, under the same trigger condition, the target relaxation measurement strategies corresponding to the same priority frequency point may be different (Table 5 takes this as an example).

table 5

The terminal is in measurement relaxation scenario 1 (stationary or low-speed moving). If the trigger condition 1 is met, the signal quality of the serving cell and neighboring cells are relatively stable, and the signal quality of the serving cell is high, the terminal may not need to perform cell reselection. Therefore, the terminal can perform RRM relaxation measurement on high-priority frequency points, and not perform RRM measurement on frequency points of the same priority or low-priority frequency points, so as to save the energy consumption of the terminal as much as possible. For example, the RRM measurement is performed according to the fifth target measurement interval. It should be understood that the fifth target measurement interval is greater than the first preset measurement interval in Table 4. If the trigger condition two is met, although the signal quality of the serving cell is poor, the signal quality of the serving cell and neighboring cells are relatively stable. In order to save the energy consumption of the terminal, the terminal can check the high priority frequency point and the same priority frequency point. And perform RRM relaxation measurement at low priority frequency points. For example, the terminal adopts the eighth target measurement to perform RRM relaxation measurement on high-priority frequency points, and adopts the ninth target measurement interval to perform RRM relaxation measurement on the same priority frequency points or low-priority frequency points. 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.

Following the example of Table 4 above, T _{higher_priority_search_relax} and T _{higher_priority_search} can satisfy the following formula (5) or formula (6)

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

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

It should be understood that N3 and N1 are not the same, and T3 and T1 are not the same.

T _{measure, NR_Inter_higher_priority_relax} and T _{measure, NR_Inte} can satisfy formula (7) or formula (8):

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 should be understood that N4 and N2 are not the same, and T4 and T2 are not the same.

The terminal is in the measurement relaxation scenario 2 (the terminal is not on the edge of the cell). If the trigger condition 1 is met, the signal quality of the serving cell is higher, which can provide the terminal with stable and better service, and the terminal does not need to perform cell reselection. Therefore, the terminal can perform RRM relaxation measurement on high-priority frequency points, and not perform RRM measurement on frequency points of the same priority or low-priority frequency points, so as to save the energy consumption of the terminal as much as possible. For example, the RRM measurement is performed according to the sixth target measurement interval. It should be understood that the sixth target measurement interval is greater than the first preset measurement interval in Table 4. If the trigger condition two is met, although the signal quality of the serving cell is not high enough, the signal of the serving cell is stable. In order to save the energy consumption of the terminal, the terminal can check the high priority frequency point, the same priority frequency point and the low priority frequency point. Perform RRM relaxation measurement. For example, the terminal adopts the tenth target measurement to perform RRM relaxation measurement on high-priority frequency points, and adopts the eleventh target measurement interval to perform RRM relaxation measurement on the same priority frequency points or low-priority frequency points. 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 smaller than the fifth target measurement interval.

That is, T _{higher_priority_search_relax} and T _{higher_priority_search} can satisfy the following formula (9) or formula (10)

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

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

It should be understood that N5 is different from N1 and N3, and T5 is different from T1 and T3.

T _{measure, NR_Inter_higher_priority_relax} and T _{measure, NR_Inte} can satisfy formula (11) or formula (12):

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

The terminal is in measurement relaxation scenario 3 (the terminal is not at the edge of the cell, and the terminal is moving or stationary at low speed). If the trigger condition 1 is met, the signal quality of the serving cell is relatively high, and the signal quality of the serving cell is relatively stable, which can provide the terminal with For stable and better service, the terminal may not need to perform cell reselection. Therefore, the terminal can perform RRM relaxation measurement on high-priority frequency points, and not perform RRM measurement on frequency points of the same priority or low-priority frequency points, so as to save the energy consumption of the terminal as much as possible. For example, the RRM measurement is performed according to the seventh target measurement interval. It should be understood that the seventh target measurement interval is greater than the first preset measurement interval in Table 4. If the trigger condition two is met, although the signal quality of the serving cell is not high enough, the signal of the serving cell is stable. In order to save the energy consumption of the terminal, the terminal can check the high priority frequency point, the same priority frequency point and the low priority frequency point. Perform RRM relaxation measurement. For example, the terminal adopts the twelfth target measurement to perform RRM relaxation measurement on high-priority frequency points, and adopts the thirteenth target measurement interval to perform RRM relaxation measurement on the same priority frequency points or low-priority frequency points. It should be understood 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.

That is, T _{higher_priority_search_relax} and T _{higher_priority_search} can satisfy the following formula (13) or formula (14)

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

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

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

T _{measure, NR_Inter_higher_priority_relax} and T _{measure, NR_Inte} can satisfy formula (15) or formula (16):

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 should be understood that N8 is different from N2, N4, and N6, and T8 is different from T2, T4, and T6. N7 is less than or equal to N5, and T8 is less than or equal to T6. Exemplarily, please refer to Table 5 for the relationship between the signal strength and the target measurement interval.

In some embodiments, in order to achieve a better load gain, the terminal may perform relaxation measurements on high-priority data. For example, for data that needs to be acquired periodically, the period of data acquisition can be increased. In other words, the measurement interval used by the terminal to measure high-priority data is smaller than the measurement interval used by the terminal to measure low-priority data or data of the same priority. 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 understood that in any RRM relaxation measurement scenario, RRM relaxation measurement can also be performed for high-priority frequency points, so as to further reduce the energy consumption of the terminal. In some embodiments, when the terminal is in the RRM relaxation measurement scenario, the RRM relaxation measurement may be performed on the high-priority frequency points by default, so as to save the energy consumption of the terminal as much as possible. In other embodiments, the base station may instruct the terminal whether to perform RRM relaxation measurement on high-priority frequency points, so as to take into account the terminal's energy consumption requirements and communication performance requirements.

S503: The base station sends instruction information to the terminal, and the terminal receives the instruction information, where the instruction information is used to indicate whether the terminal performs RRM relaxation measurement on high-priority frequency points. It should be understood that S503 is an optional step, and therefore, it is illustrated by a dotted line in FIG. 5.

The indication information may directly instruct the terminal to perform RRM relaxation measurement on high-priority frequency points, or indirectly instruct the terminal to perform RRM relaxation measurement on high-priority frequency points. Since the embodiment of this application is based on whether the terminal in the relaxation measurement scenario performs RRM relaxation measurement on the high priority frequency point, the indication information here can also be understood as indicating whether the terminal in the RRM measurement relaxation scenario performs the RRM relaxation measurement on the high priority frequency point. Perform RRM relaxation measurement at the first-level frequency point. Several possible implementations of the instruction information are introduced below.

Direct indication mode, the indication information can be m-bit information, m-bit is the first value, instructing the terminal to perform RRM relaxation measurement on high-priority frequency points, and m-bit is the second value, instructing the terminal to perform RRM on high-priority frequency points Relax the measurement.

In a certain RRM relaxation measurement scenario, if the terminal receives the indication information, the value of the indication information is the second value, that is, the terminal is instructed not to perform RRM relaxation measurement on high-priority frequency points, then the terminal can determine according to Table 2. The target relaxation measurement strategy corresponding to the RRM relaxation measurement scenario where the terminal is located performs RRM measurement. On the contrary, if the value of the indication information is the first value, that is, the terminal is instructed to perform RRM relaxation measurement on the high-priority frequency points. Then the terminal can determine the target relaxation measurement strategy to be adopted for RRM measurement according to Table 4.

The indication information can be carried in radio resource control (RRC) signaling or system information (SI), that is, the network device can broadcast the SI carrying the indication information, and the indication The information is sent to the terminal. For example, the indication information may be carried in system information block 2 (SIB2). Wherein, the indication information can be carried in information elements defined in SIB2, for example, cell reselection information (cellReselectionInfoCommon) information element in SIB2, or other possible information elements; or, the indication information can also be carried in information elements newly defined in SIB2. The embodiments of this application do not impose restrictions on the way in which the indication information is carried.

In the indirect indication mode, if the terminal receives the indication information, it can be considered that the RRM relaxation measurement is performed on the high-priority frequency point. On the contrary, if the terminal does not receive the indication information within the preset time period, it can be considered that the high-priority frequency point is not received. Click to take the RRM relaxation measurement.

In the embodiment of the present application, the network side device may indicate through the instruction information whether the terminal in the RRM relaxation measurement scenario should perform the RRM relaxation measurement on the high-priority frequency points, so as to take into account the terminal's energy consumption, communication performance, and load balance. It should be understood that the terminal measures the cell, that is, after the terminal measures the frequency points with higher, lower or equal priority, cell reselection may be performed.

Exemplarily, the indication information may be 1-bit information, and the indication information carried in SIB2 is represented by highPriorityMeasRelax, then highPriorityMeasRelax=true, then the terminal is instructed to perform RRM relaxation measurement on high-priority frequency points; if highPriorityMeasRelax=false, Then the terminal is instructed not to perform RRM relaxation measurement on the high-priority frequency points. If the terminal in the measurement relaxation scenario 1 (Low mobility criterion) receives the indication information and determines highPriorityMeasRelax=true, the terminal can use the target measurement interval in Table 4 and Table 5 (for example, the first target measurement interval, the following In the text, it is _{represented by T higher_priority_search_low_mobility} ) to perform RRM relaxation measurement on high priority frequency points. That is, T _{higher_priority_search_low_mobility is} greater than or equal to T _{higher_priority_search} .

Similarly, if the terminal in the measurement relaxation scenario 2 (Not at cell edge criterion) receives the indication information and determines that highPriorityMeasRelax=true, the terminal can use T _{higher_priority_search_low_mobility} to perform RRM relaxation measurement on high priority frequency points. Among them, T _{higher_priority_search_low_mobility is} greater than or equal to the preset measurement interval corresponding to Table 4 and Table 5, that is, T _{higher_priority_search} .

If the terminal in the measurement relaxation scenario 3 (Both low mobility criterion and not in cell edge criterion) receives the indication information, it is determined that highPriorityMeasRelax=true, and the terminal can use a _{higher_priority_search_low_mobility} _{greater than or equal to higher_priority_search} for the high priority frequency point Perform RRM relaxation measurement. It should be understood that T _{higher_priority_search} may correspond to the preset measurement interval corresponding to Table 4 and Table 5.

It should be understood that for high-priority frequency points, there is a relationship between the measurement interval shown in Table 6 and the measurement relaxation scenario.

Table 6

The above respectively introduced how the terminal performs RRM relaxation measurement for high-priority frequency points. It should be understood that the terminal measures the cell, that is, after the terminal measures the frequency points with higher, lower or equal priority, cell reselection may be performed.

Specifically, the base station that manages each cell can set the priority of the frequency point where the cell is located according to the quality of service it can provide. Usually the cell priority (CellReselectionPriority) on a frequency has a value range of (0-7). The larger the value, the higher the priority of the frequency, and the higher the reselection priority of all cells on the corresponding frequency. . In the NR system, the base station can also configure a cell reselection subpriority parameter (CellReselectionSubPriority) for each carrier, and the value of the CellReselectionSubPriority can be 0.2/0.4/0.6/0.8.

The base station that manages the cell can broadcast the measurement configuration information of the cell through a system message (for example, SIB2), which is used for terminals accessing the cell to perform RRM measurement.

Among them, 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 cell reselection priority and signal quality parameters of the frequency point where the cell is located, such as _intra- frequency measurement threshold (S intrasearch), and inter-frequency/different system measurement threshold (S _{nonintrasearch} ). It should be noted that when the signal quality is expressed by one signal quality parameter in the communication system, the above same-frequency measurement threshold and inter-frequency/different system measurement threshold also correspond to one; when the communication system is expressed by multiple signal quality parameters , The above threshold also corresponds to multiple. It should be understood that S _rxlev and S _qual in Table 7 are measured and calculated by the terminal, so they are not sent by the base station. Therefore, in Table 7, the system messages corresponding to _{S rxlev} and S _{qual are empty.}

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

When the terminal receives the SIB2, if the terminal measures that the signal quality of the serving cell satisfies the S _{rxlev of} the serving cell is greater than S _intrasearch P, and the S _{qual of} the serving cell is greater than S _intrasearch Q, the terminal starts to check the service frequency (service frequency). The measurement is performed in the neighboring cell on the frequency point where the cell is located. When the terminal measures that the signal quality of the serving cell satisfies that the S _{rxlev of} the serving cell is greater than S _{nonintrasearch} P, and the S _{qual of} the serving cell is greater than S _{nonintrasearch} Q, the terminal performs measurement on the neighboring cell on the high-priority frequency point; when When the signal quality of the serving cell measured by the terminal does not meet the above-mentioned condition, the terminal performs measurement on the high priority target frequency point, the same priority target frequency point, and the neighboring cell on the low priority frequency point.

In the same way, when the terminal is in a relaxed measurement scenario, after performing the relaxed measurement on the target frequency point, the relaxed reselection of the cell can be performed. That is, when the terminal determines that the cell reselection parameter of the target cell is greater than the first preset threshold, the terminal switches to the target cell, where the first preset threshold is greater than the second preset threshold, and the second preset threshold is It is at the cell reselection threshold when the measurement scenario is sent. In other words, that is to relax the cell reselection threshold, the first preset threshold is the threshold corresponding to the measurement relaxation 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, if the cell reselection parameter includes the signal quality parameter of the cell, the first preset threshold includes the first signal quality threshold, such as ThreshX, HighP and/or ThreshX, HighQ. The cell reselection parameter includes the cell reselection time interval, and the first preset threshold includes the first time threshold.

In a possible implementation manner, the terminal determining that the cell reselection parameter of the target cell is greater than the first preset threshold may include the terminal determining that the signal quality of the target cell is greater than the first signal quality threshold, and the terminal determining that the signal quality of the target cell is greater than the second signal One of the duration of the quality threshold exceeds the first time threshold, the second signal quality threshold is different from the first signal quality threshold, and the terminal determines that the signal quality of the target cell is greater than the first signal quality threshold and the duration exceeds the first time threshold Or multiple.

In some embodiments, after the terminal detects a high-priority cell, when the signal quality (S _qual ) of the target cell (that is, the cell reselected by the terminal) is greater than ThreshX, HighQ, and exceeds TreselectionRAT, the terminal performs cell reselection. Or, if the signal amplitude of the target cell is greater than ThreshX, HighP, in TreselectionRAT, the terminal is disconnected in the current serving cell for more than 1s, and the terminal performs cell reselection.

However, for a terminal in a relaxed measurement scenario, when the terminal meets that the signal amplitude of the target cell is greater than ThreshX, HighP, and the signal strength of the target cell is greater than ThreshX, HighQ, the signal quality of the former serving cell is better, in order to save signaling overhead And energy consumption can reduce frequent cell reselection. For this reason, in the embodiments of the present application, the threshold for cell reselection can be increased, for example, one or more of ThreshX, HighP, ThreshX, HighQ, and cell reselection time intervals can be relaxed. That is, increase ThreshXHighQ. Hereinafter, the cell handover threshold suitable for relaxed measurement is called the relaxed handover threshold, which is indicated by ThreshXHighQ_Relax. It should be understood that ThreshXHighQ_Relax is greater than ThreshX, HighQ. In the same way, the embodiment of the present application can increase TreselectionRAT to be suitable for cell reselection of relaxed measurement. Hereinafter, the cell reselection time interval suitable for relaxed measurement is referred to as the cell reselection relaxation time interval, which is indicated by TreselectionRAT_relax.

In a possible implementation, in TreselectionRAT, when the signal strength of the target cell is greater than ThreshXHighQ_Relax, the terminal can perform cell reselection according to ThreshXHighQ_Relax and TreselectionRAT; or in TreselectionRAT_relax, when the signal strength of the target cell is greater than ThreshX, HighQ, the terminal can perform cell reselection according to ThreshX, HighQ, and TreselectionRAT_relax perform cell reselection; or in TreselectionRAT_relax, when the signal strength of the target cell is greater than ThreshX, HighQ, the terminal performs cell reselection according to ThreshXHighQ_Relax and TreselectionRAT_relax, which is not limited in the embodiment of the application.

In other embodiments, the terminal may reselect cells with the same priority. For example, the terminal may follow the same-frequency cell handover mechanism, that is, sort the candidate cells according to the converted signal amplitude Rs and the converted signal quality Rn from high to low, and the terminal will reselect to the cell with the highest ranking. Among them, Rs and Rn satisfy formulas (17) and (18) respectively:

Rs=Qmeas,s+Qhyst--Qoffsettemp (17)

Rn=Qmeas,n--Qoffset--Qoffsettemp (18)

Among them, Qmeas,s is the measured signal amplitude, Qmeas,n is the measured signal quality at the corresponding frequency point, and Qoffsettemp is the temporary adjustment value for the measurement. Rn is the signal quality after conversion, Qmeas, n is the measured signal quality at the corresponding frequency point, Qhyst is the set signal amplitude threshold, and Qoffset is the measurement quality threshold. When a cell has better quality in TreselectionRAT and the terminal has been disconnected for more than 1s in the current serving cell, the terminal can perform cell reselection. When the handover to the best cell (rangeToBestCell) is not configured, that is, the base station does not configure the target cell to be handover for the terminal, the UE will reselect to the highest ranked cell. When configuring rangeToBestCell, the terminal will switch to the cell with the largest number of beams (beam) above the threshold. If there are multiple beam cells, the cell with the highest ranking will be selected.

However, the priority of the target cell is the same as the priority of the current serving cell of the terminal, and the quality of service provided to the terminal may also be the same. In this case, in order to save signaling and energy consumption, the terminal may not perform cell reselection. Therefore, in the embodiment of the present application, a terminal in a measurement relaxation scenario may not perform cell reselection after performing relaxation RRM measurement on cells of the same priority.

In other embodiments, for the reselection of lower priority cells, the terminal is disconnected from the serving cell for more than 1 second. When the signal strength of the serving cell is less than ThreshServing, LowQ, and the lower priority cell satisfies the signal in TreselectionRAT_relax If the strength is greater than ThreshX, LowQ, the terminal can reselect cells with lower priority. Or the signal amplitude of the current serving cell is less than ThreshServing, LowP, and the low priority cell satisfies the signal amplitude value greater than ThreshX, LowP in TreselectionRAT, and the terminal has been disconnected for more than 1s in the current serving cell, and the terminal can target the lower priority The cell is reselected.

In some embodiments, in a certain relaxation measurement scenario, TreselectionRAT_relax corresponding to different priority frequency points may be the same, and ThreshX, LowQ and/or ThreshServing, LowP corresponding to different priority frequency points may also be the same.

In other embodiments, in a certain relaxation measurement scenario, one or more of TreselectionRAT_relax, ThreshX, LowQ, ThreshServing, and LowP corresponding to different priority frequency points are different.

It should be understood that TreselectionRAT_relax is greater than or equal to TreselectionRAT on which a terminal that is not in the RRM relaxation measurement scenario is based on cell reselection. ThreshX, LowQ in the RRM relaxation measurement scenario is greater than or equal to ThreshX, LowQ not in the RRM relaxation measurement scenario, and ThreshServing in the RRM relaxation measurement scenario, LowP is greater than or equal to ThreshServing, LowP in the RRM relaxation measurement scenario .

In the embodiment of the present application, for a terminal in a relaxed measurement scenario, the relaxed measurement strategy used for the subsequent relaxed measurement of the target frequency point can be determined by loosening the measurement threshold. The priority of the target frequency may be higher than the priority of the frequency of the serving cell, or may be lower than or equal to the priority of the frequency of the serving cell, and the relaxation measurement threshold can be flexibly set for target frequency of different priorities , In order to take into account the terminal's communication performance and energy-saving requirements.

Further, the embodiment of the present application can relax cell reselection, that is, increase the cell reselection threshold, so as to avoid frequent cell reselection by the terminal.
