Description

Measuring method and device

The present application claims priority from a chinese patent application entitled "a method for measuring relaxation adjustment priorities" filed by the intellectual property office of the people's republic of china, application number 202010241481.0, on 31/3/2020 and incorporated herein by reference in its entirety.

Technical Field

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

Background

In a communication system, due to mobility of a terminal device, in order to ensure service continuity and communication quality of the terminal device, the terminal device in a Radio Resource Control (RRC) idle state (abbreviated as RRC _ idle state) and an RRC inactive state (abbreviated as RRC _ inactive state) generally needs to perform cell measurement, so as to implement cell reselection (reselection), thereby changing a cell where the terminal device resides to obtain continuous service.

In order to ensure that the terminal device can implement cell reselection, a base station managing a cell in a communication system usually carries measurement configuration information of the cell in a system message. Wherein the measurement configuration information may include, but is not limited to, the following measurement configuration parameters: the priority of the frequency point of the cell, the threshold for starting measurement, etc. The terminal equipment receives the system information of the service cell and the target frequency points (including the same frequency point and/or different frequency point) notified by the base station of the management service cell, and executes measurement on the adjacent cells on the target frequency points according to the measurement configuration information, and reselects the cell according to the measurement result.

In the process of performing measurement by the terminal device, the terminal device may classify the target frequency points into the following three categories according to the relative relationship between the priority of the target frequency point and the priority of the serving frequency point (the frequency point where the serving cell is located):

and the high-priority target frequency point is a target frequency point with priority higher than that of the service frequency point.

And the target frequency points with the same priority, namely the target frequency points with the priority same as that of the service frequency points.

And the low-priority target frequency point is a target frequency point with the priority lower than that of the service frequency point.

Because the adjacent cells on the high-priority target frequency points can provide better service, the communication system has different cell measurement triggering conditions for different types of target frequency points, and correspondingly has different cell reselection rules for different types of target frequency points, the terminal equipment can preferentially reselect the adjacent cells on the high-priority target frequency points, and the service quality of the terminal equipment is improved.

Since the measurement and cell reselection performed by the terminal device in the current RRC idle state and RRC inactive state are the main sources of power consumption, in order to ensure the communication performance of the terminal device and effectively save the power consumption of the terminal device, a concept of relaxation measurement is introduced in the communication field, but a scheme for realizing relaxation measurement is not discussed yet.

Disclosure of Invention

The application provides a measurement method and equipment, which are used for enabling terminal equipment to flexibly perform relaxation measurement on adjacent cells on target frequency points, so that the communication performance of the terminal equipment can be ensured, and the power consumption of the terminal equipment can be saved.

In a first aspect, an embodiment of the present application provides a measurement method, where the method includes:

when the terminal equipment determines that a set relaxation measurement triggering condition is met, entering a relaxation measurement mode; and adjusting the priority of the service frequency point from the first priority P1 to a second priority P2, wherein the service frequency point is the frequency point where the service cell is located, and P2> P1.

By the method, when the terminal equipment enters the relaxation measurement mode, the priority of the service frequency point is actively increased, so that the number of the high-priority target frequency points can be effectively reduced, the number of the measurement objects is reduced, and the power consumption expense caused by measurement can be effectively avoided.

In one possible design, P2 is configured by a base station to the terminal device; or P2 is determined by the terminal equipment according to a set rule; or P2 is protocol specific.

In a possible design, after the terminal equipment adjusts the priority of the service frequency point from P1 to P2, the terminal equipment determines a high-priority target frequency point, a target frequency point with the same priority and a target frequency point with a low priority according to the priority of P2 and the target frequency point; the terminal device may then perform measurements in the following manner:

the first method is as follows: the terminal equipment measures the high-priority target frequency point in a normal measurement mode; and the terminal equipment adopts a relaxation measurement mode to measure the target frequency points with the same priority and the target frequency points with low priority.

The second method comprises the following steps: the terminal equipment adopts a first relaxation measurement period T_{relax_1}Measuring N1 high-priority target frequency points in N0 high-priority target frequency points; and using a second relaxation measurement period T_{relax_2}Measuring M1 non-high priority target frequency points in the M0 non-high priority target frequency points; wherein the first relaxation measurement period T_{relax_1}<The second relaxation measurement period T_{relax_2}And/or, N0/N1<M0/M1, N0, N1, M0 and M1 are integers larger than 0, N1 is smaller than or equal to N0, M1 is smaller than or equal to M0, and the non-high priority target frequency points are equal priority target frequency points and low priority target frequency points.

Through the two measurement modes, the terminal equipment can realize differential measurement according to the priority of the target frequency point.

In one possible design, the relaxation measurement triggering condition is at least one or a combination of:

the moving speed of the terminal equipment is lower than a set speed threshold, the terminal equipment is not positioned at the edge of a service cell, and the co-channel interference is smaller than a set interference threshold.

In a second aspect, an embodiment of the present application further provides a measurement method, in which two sets of service frequency point priorities are stored in a terminal device, and a target frequency point is measured by using the corresponding service frequency point priorities in different scenarios. The method comprises the following steps:

in a normal measurement mode, the terminal device measures a target frequency point according to a service frequency point priority P1 corresponding to the normal measurement mode; when the terminal equipment determines that a set relaxation measurement triggering condition is met, the terminal equipment enters a relaxation measurement mode, and measures a target frequency point according to a service frequency point priority P2 corresponding to the relaxation measurement mode, wherein the service frequency point is a frequency point where a service cell is located, and P2> P1.

By the method, when the terminal equipment enters the relaxation measurement mode, the service frequency point priority corresponding to the relaxation measurement mode is directly used, and the service frequency point priority corresponding to the relaxation measurement mode is higher than the service frequency point priority corresponding to the normal measurement mode, so that the method can effectively reduce the number of high-priority target frequency points, thereby reducing the number of measurement objects and further effectively avoiding the power consumption overhead generated by measurement.

In one possible design, P2 is configured by a base station to the terminal device; or P2 is protocol specific.

In one possible design, the measuring, by the terminal device, a target frequency point according to P2 includes:

the terminal equipment determines a high-priority target frequency point, a same-priority target frequency point and a low-priority target frequency point according to P2 and the priority of the target frequency point;

the terminal equipment measures the high-priority target frequency point in a normal measurement mode; the terminal equipment adopts a relaxation measurement mode to measure the target frequency points with the same priority and the target frequency points with low priority; or the terminal equipment adopts a first relaxation measurement period T_{relax_1}Measuring N1 high-priority target frequency points in N0 high-priority target frequency points; and using a second relaxation measurement period T_{relax_2}Measuring M1 non-high priority target frequency points in the M0 non-high priority target frequency points; wherein the first relaxation measurement period T_{relax_1}<The second relaxation measurement period T_{relax_2}And/or, N0/N1<M0/M1, N0, N1, M0 and M1 are integers larger than 0, N1 is smaller than or equal to N0, M1 is smaller than or equal to M0, and the non-high priority target frequency points are equal priority target frequency points and low priority target frequency points.

In a third aspect, an embodiment of the present application further provides a measurement method, where the method includes:

the terminal equipment determines that a set relaxation measurement triggering condition is met; carrying out relaxation measurement on a target frequency point, wherein the target frequency point comprises: high priority target frequency point, equal priority target frequency point and low priority target frequency point.

By the method, the terminal equipment can perform relaxation measurement on all target frequency points, so that the power consumption of the terminal equipment can be reduced.

In one possible design, the number of the target frequency points is N0; the terminal equipment can realize relaxation measurement of the target frequency point through the following steps:

the terminal device performs relaxation measurement of the same relaxation level (the same degree) on all kinds of frequency points.

The terminal device may use the first relaxation measurement period T_relaxAnd carrying out normal measurement on the N1 target frequency points. Wherein the first relaxation measurement period T_relax>Normal measurement period T_normalAnd/or, N1<N0. N1 and N0 are integers greater than 0.

when the terminal equipment determines that the signal quality of the serving cell is within a first signal quality range, a first relaxation measurement period T is adopted_{relax_1}Measuring N1 target frequency points in N0 target frequency points;

employing a second relaxed measurement period T when the terminal device determines that the signal quality of the serving cell is within a second signal quality range_{relax_2}Measuring N2 target frequency points in N0 target frequency points;

wherein any value in the first signal quality range is greater than a value in the second signal quality range, the first relaxation measurement period T_{relax_1}>The second relaxation measurement period T_{relax_2}And/or, N0/N1>N0/M2。

Through the design, the terminal equipment can adopt a higher relaxation level to perform relaxation measurement when the signal quality of a serving cell is higher; when the signal quality of the serving cell is low, a lower level of relaxation is used for relaxation measurements. Therefore, the terminal equipment can flexibly carry out relaxation measurement on the target frequency point according to the signal quality intensity of the serving cell, thereby ensuring the communication performance of the terminal equipment and effectively avoiding the power consumption overhead generated by measurement.

In one possible design, the target frequency points comprise P0 high-priority target frequency points and Q0 non-high-priority target frequency points, and the Q0 non-high-priority target frequency points comprise equal-priority target frequency points and low-priority target frequency points; the terminal equipment can realize relaxation measurement of the target frequency point through the following steps:

the terminal equipment adopts a first relaxation measurement period T_{relax_1}Measuring P1 high-priority target frequency points in the P0 high-priority target frequency points;

the terminal equipment adopts a second relaxation measurement period T_{relax_2}Measuring Q1 non-high priority target frequency points in Q0 non-high priority target frequency points;

wherein the first relaxation measurement period T_{relax_1}<The second relaxation measurement period T_{relax_2}And/or, P0/P1<Q0/Q1, P0, P1, Q0 and Q1 are integers more than 0, P1 is less than or equal to P0, and Q1 is less than or equal to Q0.

Through the design, the terminal equipment can perform relaxation measurement on non-high-priority target frequency points by adopting a higher relaxation level, and perform relaxation measurement on high-priority target frequency points by adopting a lower relaxation level. The method can realize the differentiation of relaxation measurement of different types of target frequency points, thereby ensuring the communication performance of the terminal equipment and effectively avoiding the power consumption expense generated by measurement.

when the terminal equipment determines that the signal quality of the serving cell is within a first signal quality range, a first high-priority relaxation measurement period T is adopted_{high_relax_1}Measuring P1 high-priority target frequency points in the P0 high-priority target frequency points; relaxation of the measurement period T with a first non-high priority_{nonhigh_relax_1}Measuring Q1 non-high priority target frequency points in Q0 non-high priority target frequency points;

wherein the first non-high priority relaxation measurement period T_{high_relax_1}<Said first non-high priority relaxation measurement period T_{nonhigh_relax_1}And/or, P0/P1<Q0/Q1, P0, P1, Q0 and Q1 are integers more than 0, P1 is less than or equal to P0, and Q1 is less than or equal to Q0;

employing a second high priority relaxation measurement period T when the terminal device determines that the signal quality of the serving cell is within a second signal quality range_{high_relax_2}Measuring P2 high-priority target frequency points in the P0 high-priority target frequency points; using a second non-high priority relaxation measurement period T_{nonhigh_relax_2}Measuring Q2 non-high priority target frequency points in Q0 non-high priority target frequency points;

wherein the second non-high priority relaxation measurement period T_{high_relax_2}<The second non-high priority relaxation measurement period T_{nonhigh_relax_2}And/or, P0/P2<Q0/Q2, P2 and Q2 are integers more than 0, P2 is less than or equal to P0, and Q2 is less than or equal to Q0;

any value in the first signal quality range is greater than a value in the second signal quality range, and the first non-high priority relaxation measurement period T_{high_relax_1}>The second non-high priority relaxation measurement period T_{high_relax_2}(ii) a Said first non-high priority relaxation measurement period T_{nonhigh_relax_1}>The second is not highPriority relaxation measurement period T_{nonhigh_relax_2}；P0/P2>P0/P2；Q0/Q1>Q0/Q2。

Through the design, the terminal equipment can flexibly carry out relaxation measurement on the target frequency point according to two dimensions of the signal quality of the serving cell and the type of the target frequency point, so that the communication performance of the terminal equipment can be ensured, and the power consumption expense caused by measurement can be effectively avoided.

In a fourth aspect, an embodiment of the present application further provides a measurement method, in which a terminal device may execute different measurement strategies according to different currently-satisfied relaxation measurement trigger conditions.

Strategy 1: when the terminal equipment determines that the moving speed of the terminal equipment is lower than a set threshold, carrying out normal measurement (namely, not carrying out relaxation measurement) on a high-priority target frequency point, and carrying out relaxation measurement on a non-high-priority target frequency point; or the terminal device may perform relaxation measurement on the high-priority target frequency point by using the first relaxation level, and perform relaxation measurement on the non-high-priority target frequency point by using the second relaxation level. Wherein the first relaxation level is lower than the second relaxation level.

When the condition that the moving speed of the terminal equipment is lower than the set threshold value is met, the terminal equipment is considered to be possibly positioned at the edge of a service cell and the cell reselection requirement is possibly existed, so that the terminal equipment can not perform relaxation measurement on a high-priority target frequency point or perform relaxation measurement with a lower relaxation level on the high-priority target frequency point through the steps, the probability that the terminal equipment cell reselects the adjacent cell on the high-priority target frequency point can be improved, the communication performance of the terminal equipment can be ensured, and the power consumption overhead generated by measurement can be effectively avoided.

Strategy 2: when the terminal device determines that the terminal device is not located at the edge of the serving cell, the terminal device may perform relaxation measurement on the high-priority target frequency point by using a third relaxation level, and perform relaxation measurement on the non-high-priority target frequency point by using a fourth relaxation level. Wherein the third relaxation level is lower than the fourth relaxation level.

Under the condition that the terminal equipment is not positioned at the edge of the service cell, considering that the moving speed of the terminal equipment is high, the signal quality of the service cell received by the terminal equipment is possibly unstable, and the terminal equipment has the requirement of cell reselection, therefore, the terminal equipment can adopt different relaxation levels to respectively perform relaxation measurement on a high-priority target frequency point and a non-high-priority target frequency point through the steps, so that the communication performance of the terminal equipment can be ensured, and the power consumption overhead generated by the measurement can be effectively avoided.

Strategy 3: when the moving speed of the terminal equipment is lower than a set threshold value and the terminal equipment is not positioned at the edge of a service cell, the terminal equipment can adopt a fifth relaxation level to perform relaxation measurement on a high-priority target frequency point, adopt a sixth relaxation level to perform relaxation measurement on a non-high-priority target frequency point or not perform measurement on the non-high-priority target frequency point.

When the conditions are met, the probability of cell reselection of the terminal equipment is low, so that the terminal equipment can perform relaxation measurement on the high-priority target frequency point and the non-high-priority target frequency point by adopting a high relaxation level through the steps, or does not perform measurement on the non-high-priority target frequency point, and therefore power consumption overhead generated by measurement can be effectively avoided.

In the method, the higher the relaxation level adopted by the terminal equipment is, the lower the measurement frequency used by the terminal equipment is (the larger the relaxation measurement period is), and the larger the reduction degree of a measurement object (an actually measured target frequency point) is.

In a fifth aspect, an embodiment of the present application provides a terminal device, which includes a unit configured to perform each step in any one of the above aspects.

In a sixth aspect, an embodiment of the present application provides a terminal device, including at least one processing element and at least one storage element, where the at least one storage element is configured to store programs and data, and the at least one processing element is configured to read and execute the programs and data stored by the storage element, so that the method provided in any of the above aspects of the present application is implemented.

In a seventh aspect, this application embodiment also provides a computer program, which when run on a computer, causes the computer to execute the method provided in any one of the above aspects.

In an eighth aspect, the present application further provides a computer-readable storage medium, in which a computer program is stored, and when the computer program is executed by a computer, the computer is caused to execute the method provided in any one of the above aspects.

Detailed Description

The application provides a measurement method and equipment, which are used for enabling terminal equipment to flexibly perform relaxation measurement on adjacent cells on target frequency points, so that the communication performance of the terminal equipment can be ensured, and the power consumption of the terminal equipment can be saved. The method and the device are based on the same technical conception, and because the principles of solving the problems of the method and the device are similar, the implementation of the device and the method can be mutually referred, and repeated parts are not repeated.

Hereinafter, some terms in the present application are explained to facilitate understanding by those skilled in the art.

1) A terminal device is a device that provides voice and/or data connectivity to a user. The terminal device may also be referred to as a User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (MT), and so on.

For example, the terminal device may be a handheld device, a vehicle-mounted device, or the like having a wireless connection function. Currently, some examples of terminal devices are: a mobile phone (mobile phone), a tablet computer, a notebook computer, a palm top computer, a Mobile Internet Device (MID), a wearable device, a Virtual Reality (VR) device, an Augmented Reality (AR) device, a wireless terminal in industrial control (industrial control), a wireless terminal in self driving (self driving), a wireless terminal in remote surgery (remote medical supply), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation safety (smart security), a wireless terminal in city (smart city), a wireless terminal in home (smart home), and the like.

2) And the base station is a device for accessing the terminal device to the wireless network in the communication system. The base station serves as a node in a radio access network, and may also be referred to as a network device, and may also be referred to as a Radio Access Network (RAN) node (or device).

Currently, some examples of base stations are: a gbb, an evolved Node B (eNB), a Transmission Reception Point (TRP), a Radio Network Controller (RNC), a Node B (NB), a Base Station Controller (BSC), a Base Transceiver Station (BTS), a home base station (e.g., a home evolved Node B or a home Node B, HNB), or a Base Band Unit (BBU), etc.

In addition, in a network structure, the base station may include a Centralized Unit (CU) node and a Distributed Unit (DU) node. The structure separates the protocol layers of the eNB in a Long Term Evolution (LTE) system, the functions of part of the protocol layers are controlled in the CU in a centralized way, the functions of the rest part or all of the protocol layers are distributed in the DU, and the CU controls the DU in a centralized way.

3) And the reference signal is sent by the cell managed by the base station through the base station and is used for enabling the terminal equipment to measure so as to realize the processes of cell reselection, cell switching, beam determination and the like. For example, in the embodiment of the present application, the reference signal may be a Synchronization Signal Block (SSB), a channel state information-reference signal (CSI-RS), or the like.

4) The signal quality is measured for the terminal device aiming at the cell, and the obtained measurement result may include one or more of the following signal quality parameters:

signal amplitude (S)_rxlev) Signal strength (S)_qual) Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), signal to noise ratio (SNR), signal to interference plus noise ratio (SINR), and the like.

5) The measurement configuration information of the cell is broadcasted by a system message (e.g., system information blocks 2 (SIB 2)) for a base station managing the cell, and is used for performing cell measurement by a terminal device accessing the cell.

Wherein, the measurement configuration information includes a priority (cell reselection priority) of a frequency point where the cell is located, and a threshold (S) of co-frequency measurement_intrasearch) And threshold (S) for inter-frequency/inter-system measurements_{nonintrasearch}). It should be noted that, when the signal quality is represented by a signal quality parameter in the communication system, the above threshold for starting the measurement of the same frequency and the threshold for starting the measurement of the different frequency/different system are also 1 correspondingly; when represented by a plurality of signal quality parameters in the communication system, the above thresholds are also correspondingly a plurality.

Illustratively, when signal quality is represented by signal amplitude and signal strength in a communication system, the synchronization measurement thresholds include: signal amplitude threshold (S) for common frequency measurement_intrasearchP) and signal strength threshold (S) for co-frequency measurements_intrasearchQ). In this scenario, when a terminal device using the cell as a serving cell measures that the signal quality of the cell meets the following conditions, the terminal device starts to perform common-frequency measurement, that is, to perform measurement on a neighboring cell on a serving frequency point: signal amplitude (S) in signal quality of the cell_rxlev) Greater than S_intrasearchP, and signal strength (S) in signal quality of the cell_qual) Greater than S_intrasearchQ。

Meanwhile, the threshold of the inter-frequency/inter-system measurement includes: signal amplitude threshold (S) for pilot/pilot system measurements_{nonintrasearch}P) and signal strength threshold (S) measured by pilot/pilot system_{nonintrasearch}Q). In this scenario, when a terminal device using the cell as a serving cell measures that the signal quality of the cell meets the following conditions, the terminal device starts to perform pilot frequency measurement, that is, to perform measurement on neighboring cells on other target frequency points different from the serving frequency point: signal amplitude (S) in signal quality of the cell_rxlev) Greater than S_{nonintrasearch}P, and signal strength (S) in signal quality of the cell_qual) Greater than S_{nonintrasearch}Q。

6) The measurement provided by the embodiment of the present application includes RRM measurement and Radio Link Monitoring (RLM) measurement. The terminal device measures the target frequency point, actually measures the adjacent region on the target frequency point, and the target frequency point and the adjacent region can be equal.

7) "and/or" describe the association relationship of the associated objects, indicating that there may be three relationships, e.g., a and/or B, which may indicate: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

In the present application, the plural number means two or more.

In addition, it is to be understood that the terms first, second, etc. in the description of the present application are used for distinguishing between the descriptions and not necessarily for describing a sequential or chronological order.

The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

Fig. 1 shows an architecture of a possible communication system for measurement usage provided by an embodiment of the present application. Referring to fig. 1, the communication system includes a base station and a terminal device.

The base station provides radio access related services for the terminal equipment through the managed cell, and realizes functions of a radio physical layer, resource scheduling and radio resource management, Quality of Service (QoS) management, radio access control and mobility management (such as cell reselection and handover).

Wherein each base station is responsible for managing at least one cell. As shown, base station a is responsible for managing cell a, base station B is responsible for managing cell B, and base station C is responsible for managing cell C.

In the communication system, each cell provides access service for the terminal equipment by using the frequency spectrum resources of the corresponding frequency points. It should be noted that the frequency points used by different cells may be the same or different. In addition, the communication technology used by each cell is not limited in the present application, and the communication technologies used by different cells may be the same or different. For example, cell a-cell G are all LTE cells using 4G communication technology; or the cells a-G are all NR cells using 5G communication technology; or part of the cells are LTE cells and part of the cells are NR cells.

The terminal equipment is equipment which accesses a network through a cell managed by the base station.

And the base station is connected with the terminal equipment through a Uu interface, so that the communication between the terminal equipment and the base station is realized.

In addition, The architecture shown in fig. 1 may be applied to various communication scenarios, for example, a fifth Generation (5G) communication system, a future sixth Generation communication system and other communication systems that evolve, a Long Term Evolution (Long Term Evolution, LTE) communication system, a vehicle to anything (V2X), a Long Term Evolution-vehicle networking (LTE-V), a vehicle to vehicle (V2V), a vehicle networking, a Machine Type communication (Machine Type Communications, MTC), an internet of things (MTC), an IoT, a Long Term Evolution-Machine to Machine (LTE-Machine to Machine, LTE-M), a Machine to Machine (M2M), and other communication scenarios.

In the communication system shown in fig. 1, due to the mobility of the terminal device, the terminal device may move from the coverage of one cell to the coverage of another cell, as shown in the figure, the terminal device moves from cell a to cell b, and therefore, the terminal device needs to change the cell where it resides continuously through measurement to ensure the continuity of the service. In order to achieve the above object, the terminal device needs to be implemented through a cell reselection or a cell handover process.

In order to ensure that the terminal equipment can realize cell reselection or cell handover, the base station managing each cell broadcasts the measurement configuration information of the cell in the cell coverage area managed by the base station through the system message. Therefore, after the terminal equipment receives the measurement configuration information of the service cell, the terminal equipment performs measurement on the adjacent cell on the target frequency point according to the measurement configuration information, and performs cell reselection according to the measurement result. The target frequency point may be notified to the terminal device by a base station managing the serving cell through a system message or an RRC message.

In order to make the cell reselection of the terminal device more flexible, the base station managing each cell may set the priority of the frequency point where the cell is located according to the conditions of the service quality and the like that the base station can provide. Generally, the value range of the priority of the frequency point is (0-7), and the larger the value is, the higher the priority of the frequency point is.

For example, in cell 1 on frequency point 1, the system bandwidth may be larger, the signal quality is better, or a higher transmission rate (for example, a hot spot cell) can be provided, and the base station managing cell 1 may set the priority of frequency point 1 to 7 in the measurement configuration information of cell 1.

For another example, if the system bandwidth, signal quality, and transmission rate of the cell on frequency point 2 are not as good as those of the cell on frequency point 1, the base station managing cell 2 may set the priority of frequency point 2 to 5 in the measurement configuration information of cell 2.

For another example, the cell on the frequency point 3 may have a smaller system bandwidth, a poorer signal quality, or a lower transmission rate, so the base station managing the cell 3 may set the priority of the frequency point 3 to 3 in the measurement configuration information of the cell 3.

Therefore, before measurement, the terminal equipment can divide the target frequency points into three types according to the relative relation between the priority of each target frequency point and the priority of the service frequency point: high priority target frequency point, equal priority target frequency point, low priority target frequency point.

As can be seen from the above description, the terminal device measures the neighboring cells on the low priority target frequency point and the equal priority target frequency point, so as to solve the cell coverage problem of the terminal device. As shown in fig. 1, a cell a is a serving cell of a terminal device, and when the terminal device moves to an edge of the cell a, the terminal device initiates measurement of neighboring cells (cell b, cell c, etc.) on such frequency points. Therefore, when the terminal moves to the coverage range of the adjacent cell on the frequency point, the terminal equipment can reselect the adjacent cell with better signal quality. The terminal equipment measures the adjacent region on the high-priority target frequency point, and hopes to reside in the adjacent region of the frequency point, so as to obtain better service.

In order to consider both the cell coverage problem and the service quality problem of the terminal device, the triggering conditions for the terminal device to measure the neighboring cells of different priority target frequency points are also different: in general, when terminal equipment determines that the signal quality of a serving cell is greater than a threshold for pilot frequency/inter-system measurement, only adjacent cells on a high-priority target frequency point are measured; and when the terminal equipment determines that the signal quality is not greater than the threshold of the pilot frequency/pilot system measurement, measuring adjacent regions on the high-priority target frequency point, the equal-priority target frequency point and the low-priority target frequency point.

Currently, in order to reduce the power consumption of the terminal device, the terminal device may enter an RRC idle state and an RRC inactive state. However, in this state, the terminal device performs measurement and cell reselection, which are major sources of its power consumption. Therefore, in order to ensure the communication performance of the terminal device and effectively save the power consumption of the terminal device, the concept of relaxation measurement is introduced in the communication field. When performing relaxation measurement, the terminal device may reduce the measurement object (e.g., reduce the number of target frequency points, reduce the number of neighboring cells to be measured), or reduce the number of measurements (e.g., increase the detection delay T)_detectIncreasing the measurement delay T_measureOr increasing the evaluation delay T_evaluate)。

The terminal device may switch between relaxed and normal measurements and the criteria for triggering mode switching at least need to consider whether the terminal device is at the cell edge or whether the UE is stationary or has a low moving speed, etc.

In order to enable the terminal device to flexibly perform relaxation measurement on the neighboring cell on the target frequency point, so that the communication performance of the terminal device can be ensured and the power consumption of the terminal device can be saved, the embodiment of the application provides a measurement method. The method may be applied to the communication system shown in fig. 1, and the method provided by the embodiment of the present application is described in detail below with reference to fig. 2A.

S201 a: and when the terminal equipment determines that the set relaxation measurement triggering condition is met, entering a relaxation measurement mode.

In one embodiment, the relaxation measurement trigger condition is at least one or a combination of:

S202 a: the terminal equipment adjusts the priority of the service frequency point from the first priority P1 to the second priority P2, wherein the service frequency point is the frequency point where the service cell is located, and P2> P1. Wherein, P1 is sent by the bs managing the serving cell through the system message SIB2, and P1 is the cell reselection priority in the measurement configuration information included in SIB 2.

In the current measurement scheme, when the terminal device performs the neighbor cell measurement, the terminal device can unconditionally and continuously measure the neighbor cell on the high-priority target frequency point. Therefore, even if the terminal device enters the relaxation measurement mode, the terminal device only performs relaxation measurement on the neighboring cells on the non-high-priority target frequency point, and still performs normal measurement on the neighboring cells on the high-priority target frequency point. Through the steps, the terminal equipment can actively increase the priority of the service frequency points, so that the number of the high-priority target frequency points can be effectively reduced. Therefore, the terminal equipment can reduce the number of the measurement objects by actively increasing the priority of the service frequency points, and further can effectively avoid the power consumption overhead generated by cell measurement.

In one embodiment, the P2 is configured by a base station to the terminal device. Illustratively, the base station may carry the P2 in a system message (e.g., SIB 2).

Exemplarily, the code of SIB2 carrying P2 is as follows:

In another embodiment, the P2 may be protocol specific and stored to the terminal device.

In yet another embodiment, the P2 may be determined by the terminal device according to a setting rule, where the setting rule may be configured by the base station to the terminal device or specified by a protocol. For example, the setting rule is to adjust to the highest priority, or to increase 3 priorities based on the priority of the original service frequency point.

In yet another embodiment, the P2 may request the base station configuration for the terminal device. For example, the terminal device sends a request message to the base station after entering the relaxation measurement mode, and the base station feeds back a response message after receiving the request message, where the response message includes P2.

In an embodiment, after the terminal device adjusts the priority of the service frequency point from P1 to P2, the priority target frequency point, the equal priority target frequency point, and the low priority target frequency point may be re-determined according to P2 and the priority of the target frequency point. Then the terminal equipment adopts a normal measurement mode to carry out normal measurement on the high-priority target frequency point; and measuring the target frequency points with the same priority and the target frequency points with the low priority by adopting a relaxation measurement mode.

In another embodiment, after the terminal device adjusts the priority of the service frequency point from P1 to P2, the priority target frequency point, the equal priority target frequency point, and the low priority target frequency point may be re-determined according to P2 and the priority of the target frequency point. Then the terminal equipment can simultaneously carry out relaxation measurement on the high-priority target frequency point and the non-high-priority target frequency point, but the relaxation level of the high-priority target frequency point is lower than that of the non-high-priority target frequency point. Specifically, the terminal device may perform relaxation measurement on the high-priority target frequency point and the non-high-priority target frequency point respectively through the following steps:

the terminal equipment adopts a first relaxation measurement period T_{relax_1}Measuring N1 high-priority target frequency points in N0 high-priority target frequency points;

the terminal equipment adopts a second relaxation measurement period T_{relax_2}Measuring M1 non-high priority target frequency points in the M0 non-high priority target frequency points;

Through the implementation mode, the terminal equipment can also perform relaxation measurement on the high-priority target frequency point, so that the power consumption overhead of the terminal equipment is further reduced.

The embodiment of the application provides a measurement method, in the method, when a terminal device enters a relaxation measurement mode, priority of a service frequency point is actively increased, so that the number of high-priority target frequency points can be effectively reduced, the number of measurement objects is reduced, and power consumption overhead caused by measurement can be effectively avoided.

And the terminal equipment measures the target frequency point according to P1 in a normal measurement mode.

In one embodiment, P1 is the cell reselection priority carried in the measurement configuration information. P2 may also be referred to as serving cell reselection priority _ Relax in relaxed measurement mode. The P2 and P1 are configured to the terminal equipment by a base station through a system message or an RRC message. Illustratively, the base station may carry the P2 in a system message (e.g., SIB 2).

Exemplarily, the code of SIB2 carrying P2 is as follows:

the underlined code "cell reselection priority" represents P1, and "cell reselection priority _ Relax" is P2.

In another embodiment, the P2 may be protocol specific and stored within the terminal device.

The terminal equipment measures the target frequency point according to P2, and the method comprises the following steps:

The second method comprises the following steps: the terminal equipment can simultaneously carry out relaxation measurement on the high-priority target frequency point and the non-high-priority target frequency point, but the relaxation level of the high-priority target frequency point is lower than that of the non-high-priority target frequency point. Specifically, the terminal device may perform relaxation measurement on the high-priority target frequency point and the non-high-priority target frequency point respectively through the following steps:

The embodiment of the application provides a measuring method, in the method, when a terminal device enters a relaxation measuring mode, service frequency point priority corresponding to the relaxation measuring mode is directly used, and the service frequency point priority corresponding to the relaxation measuring mode is higher than that corresponding to a normal measuring mode, so that the method can effectively reduce the number of high-priority target frequency points, the number of measuring objects is reduced, and power consumption overhead caused by measurement can be effectively avoided.

In order to enable the terminal device to flexibly perform relaxation measurement on the neighboring cell on the target frequency point, so that the communication performance of the terminal device can be ensured and the power consumption of the terminal device can be saved, the embodiment of the application provides a measurement method.

In a first embodiment, the terminal device performs relaxation measurement of the same relaxation level (equal degree) for all kinds of frequency points.

Illustratively, the number of the target frequency points configured by the base station is N0. When the relaxation measurement triggering condition is not met, the terminal equipment uses a normal measurement period T_normalAnd carrying out normal measurement on the N0 target frequency points. The terminal device may use the first relaxation measurement period T when performing S302_relaxFor N1 target frequenciesThe spot was measured normally. Wherein the first relaxation measurement period T_relax>Normal measurement period T_normalAnd/or, N1<N0. N1 and N0 are integers greater than 0.

In a second embodiment, the terminal device performs relaxation measurement of the same level on all kinds of frequency points, but performs relaxation measurement of different relaxation levels according to the strength of the signal quality of the serving cell.

Illustratively, the number of the target frequency points configured by the base station is N0, and the terminal device maintains a plurality of signal quality ranges, each corresponding to a different relaxation level. The larger the signal quality range is, the larger the corresponding relaxation level is. And the larger the relaxation level is, the lower the measurement frequency of the terminal equipment on the target frequency point is or the smaller the number of the target frequency points to be measured is. It should be noted that the number of the plurality of signal quality ranges is not limited in the present application, for example, 2 or 3.

Optionally, the terminal device may determine the multiple signal quality ranges according to a start measurement threshold. For example, the terminal device may set two signal quality ranges: the signal quality range is 1 and is larger than the threshold S for starting the different frequency/different system measurement_{nonintrasearch}(ii) a The signal quality range is 2 and is less than or equal to the threshold S for starting the different frequency/different system measurement_{nonintrasearch}. When the terminal equipment determines that the signal quality of the serving cell is within the signal quality range 1, carrying out relaxation measurement on the N0 target frequency points by adopting a higher relaxation level; and when the terminal equipment determines that the signal quality of the serving cell is within the signal quality range 2, performing relaxation measurement on the N0 target frequency points by adopting a lower relaxation level.

Illustratively, the terminal device may perform relaxation measurement according to the strength of the signal quality of the serving cell by:

wherein any value in the first signal quality range is greater than a value in the second signal quality range, the first relaxation measurement period T_{relax_1}>The second relaxation measurement period T_{relax_2}And/or, N0/N1>N0/M2. In addition, the first relaxation measurement period T_{relax_1}And said second relaxation measurement period T_{relax_2}Are all greater than the normal measurement period T_normal。

Through the steps, the terminal equipment can adopt a higher relaxation level to perform relaxation measurement when the signal quality of the serving cell is higher; when the signal quality of the serving cell is low, a lower level of relaxation is used for relaxation measurements. Therefore, the terminal equipment can flexibly carry out relaxation measurement on the target frequency point according to the signal quality intensity of the serving cell, thereby ensuring the communication performance of the terminal equipment and effectively avoiding the power consumption overhead generated by measurement.

In a third embodiment, the terminal device may perform relaxation measurement of different relaxation levels according to different types of target frequency points. The following description will take an example in which the target frequency points include P0 high-priority target frequency points and Q0 non-high-priority target frequency points. The Q0 non-high priority target frequency points comprise equal priority target frequency points and low priority target frequency points.

Illustratively, the terminal device may perform relaxation measurement on the target frequency point by the following steps:

the terminal equipment adopts a second relaxation measurement period T_{relax_2}For Q1 non-high priority target frequency points in Q0 non-high priority target frequency pointsCarrying out measurement;

Through the steps, the terminal equipment can perform relaxation measurement on the non-high-priority target frequency point by adopting a higher relaxation level, and perform relaxation measurement on the high-priority target frequency point by adopting a lower relaxation level. The method can realize the differentiation of relaxation measurement of different types of target frequency points, thereby ensuring the communication performance of the terminal equipment and effectively avoiding the power consumption expense generated by measurement.

In a fourth embodiment, with reference to the implementation principles of the second and third embodiments, the terminal device may perform relaxation measurement of different relaxation levels for different types of target frequency points according to the strength of the signal quality of the serving cell. The following description will continue by taking an example in which the target frequency points include P0 high-priority target frequency points and Q0 non-high-priority target frequency points. The Q0 non-high priority target frequency points comprise equal priority target frequency points and low priority target frequency points.

when the terminal equipment determines that the signal quality of the serving cell is within a first signal quality range, a first high-priority relaxation measurement period T is adopted_{high_relax_1}Measuring P1 high-priority target frequency points in the P0 high-priority target frequency points; relaxation of the measurement period T with a first non-high priority_{nonhigh_relax_1}And measuring Q1 non-high priority target frequency points in the Q0 non-high priority target frequency points. Wherein the first non-high priority relaxation measurement period T_{high_relax_1}<Said first non-high priority relaxation measurement period T_{nonhigh_relax_1}And/or, P0/P1<Q0/Q1, P0, P1, Q0, Q1 are integers greater than 0, P1 is less than or equal to P0, Q1 is less than or equal to P0Or equal to Q0;

employing a second high priority relaxation measurement period T when the terminal device determines that the signal quality of the serving cell is within a second signal quality range_{high_relax_2}Measuring P2 high-priority target frequency points in the P0 high-priority target frequency points; using a second non-high priority relaxation measurement period T_{nonhigh_relax_2}Measuring Q2 non-high priority target frequency points in Q0 non-high priority target frequency points; wherein the second non-high priority relaxation measurement period T_{high_relax_2}<The second non-high priority relaxation measurement period T_{nonhigh_relax_2}And/or, P0/P2<Q0/Q2, P2 and Q2 are integers more than 0, P2 is less than or equal to P0, and Q2 is less than or equal to Q0.

It should be noted that, in the above steps, any value in the first signal quality range is greater than that in the second signal quality range, and the first non-high priority relaxation measurement period T is greater than that in the first signal quality range_{high_relax_1}>The second non-high priority relaxation measurement period T_{high_relax_2}(ii) a Said first non-high priority relaxation measurement period T_{nonhigh_relax_1}>The second non-high priority relaxation measurement period T_{nonhigh_relax_2}；P0/P2>P0/P2；Q0/Q1>Q0/Q2。

Through the steps, the terminal equipment can flexibly carry out relaxation measurement on the target frequency point according to two dimensions of the signal quality of the serving cell and the type of the target frequency point, so that the communication performance of the terminal equipment can be ensured, and the power consumption expense caused by measurement can be effectively avoided.

In order to enable the terminal device to flexibly perform relaxation measurement on the neighboring cell on the target frequency point, so that the communication performance of the terminal device can be ensured and the power consumption of the terminal device can be saved, the embodiment of the application provides a measurement method. The method can be applied to the communication system shown in fig. 1, and the method provided by the embodiment of the present application is described in detail below with reference to fig. 4.

S401: the terminal equipment determines that the set relaxation measurement triggering condition is met. The relaxation measurement trigger condition includes: the moving speed of the terminal equipment is lower than a set threshold value, and/or the terminal equipment is not positioned at the edge of a service cell.

S402: when the relaxation measurement trigger condition is: the moving speed of the terminal equipment is lower than a set threshold, the terminal equipment performs normal measurement (namely, relaxation measurement is not performed) on the high-priority target frequency point, and performs relaxation measurement on the non-high-priority target frequency point; or the terminal device may perform relaxation measurement on the high-priority target frequency point by using the first relaxation level, and perform relaxation measurement on the non-high-priority target frequency point by using the second relaxation level. The first relaxation level is lower than the second relaxation level, and the specific implementation process may refer to the description in the third implementation manner in the embodiment shown in fig. 3, which is not described herein again.

In the case of S402, considering that the terminal device may be located at the edge of the serving cell and there may be a need for cell reselection, the terminal device may not perform relaxation measurement on the high-priority target frequency point through the above steps, or perform relaxation measurement of a lower relaxation level on the high-priority target frequency point, so that the probability that the terminal device cell reselects the neighboring cell on the high-priority target frequency point may be improved, thereby ensuring the communication performance of the terminal device and effectively avoiding power consumption overhead caused by measurement.

S403: when the relaxation measurement trigger condition is: the terminal equipment is not positioned at the edge of the service cell, the terminal equipment can adopt a third relaxation level to perform relaxation measurement on the high-priority target frequency point, and adopts a fourth relaxation level to perform relaxation measurement on the non-high-priority target frequency point. The third relaxation level is lower than the fourth relaxation level, and the specific implementation process may refer to the description in the third implementation manner in the embodiment shown in fig. 3, which is not described herein again.

Wherein the third relaxation level is higher than the first relaxation level and the fourth relaxation level is higher than the second relaxation level.

In the case of S403, considering that the moving speed of the terminal device is high, the quality of the signal received by the terminal device in the serving cell may be unstable, and the terminal device has a requirement for cell reselection, the terminal device may perform relaxation measurement on the high-priority target frequency point and the non-high-priority target frequency point respectively by using different relaxation levels through the above steps, thereby ensuring the communication performance of the terminal device and effectively avoiding power consumption overhead caused by the measurement.

S404: when the relaxation measurement trigger condition is: when the moving speed of the terminal equipment is lower than a set threshold value and the terminal equipment is not positioned at the edge of the service cell, the terminal equipment can adopt a fifth relaxation level to perform relaxation measurement on the high-priority target frequency point, and adopt a sixth relaxation level to perform relaxation measurement on the non-high-priority target frequency point, or does not perform measurement on the non-high-priority target frequency point.

Wherein the fifth relaxation level is lower than the sixth relaxation level, the fifth relaxation level being higher than the third relaxation level.

In S404, the probability of cell reselection of the terminal device is low, so that the terminal device can perform relaxation measurement on both the high-priority target frequency point and the non-high-priority target frequency point with a higher relaxation level through the above steps, or does not perform measurement on the non-high-priority target frequency point, thereby effectively avoiding power consumption overhead caused by measurement.

It should be noted that, the higher the relaxation level adopted by the terminal device is, the lower the measurement frequency used by the terminal device is (the larger the relaxation measurement period is), the greater the reduction degree of the measurement object (the target frequency point actually measured) is. For example, assume that the relaxation measurement period T used for the ith relaxation level_{relax_i}The number of the high-priority target frequency points configured by the base station is P0, and the number of the non-high-priority target frequency points is Q0; when the terminal equipment uses the first relaxation level, the third relaxation level and the fifth relaxation level, the number of actually measured high-priority target frequency points is P1, P3 and P5 respectively; when the terminal equipment uses the second relaxation level, the fourth relaxation level and the sixth relaxation level, the number of the actually measured non-high priority target frequency points is Q2, Q4 and Q6.Then the relaxation measurement period T used for the (i + 1) th relaxation level_{relax_i+1}Relaxation measurement period T greater than that used for the ith relaxation level_{relax_i}. And, P1/P0>Q2/Q0>P3/P0>Q4/Q0>P5/P0>Q6/Q0。
