technical field

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

Background technique

In the communication system, due to the mobility of the terminal equipment, in order to ensure the service continuity and communication quality of the terminal equipment, it is in the radio resource control (radio resource control, RRC) idle state (abbreviated as RRC_idle state) and RRC inactive state (abbreviated as A terminal device in the RRC_inactive state usually needs to perform radio resource management (radioresource management, RRM) measurement, so as to implement cell reselection (reselection), so as to change the cell it resides in to obtain continuous services. The RRM measurement is cell measurement, which specifically includes intra-frequency measurement and inter-frequency/inter-system measurement.

In order to ensure that the terminal equipment can realize cell reselection, the base station managing the cell in the communication system usually carries the measurement configuration information of the cell in the 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 where the cell is located, the threshold for starting RRM measurement, and the like. After receiving the system message of the serving cell and the target frequency point (including the same frequency point and/or different frequency point) notified by the base station managing the serving cell, the terminal device will measure the frequency points on the target frequency point according to the measurement configuration information therein. Neighboring cells perform RRM measurement and perform cell reselection according to the measurement results.

Wherein, during the RRM measurement process performed by the terminal device, 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), the terminal device can divide the target frequency point into the following three categories:

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

The target frequency point with the same priority, that is, the target frequency point with the same priority as that of the service frequency point.

The low-priority target frequency point is a target frequency point whose priority is lower than that of the service frequency point.

Since neighboring cells on high-priority target frequencies can provide better services, the trigger conditions for cell RRM measurement set by the communication system for different types of target frequencies are different, and the corresponding cell reselection settings for different types of target frequencies The rules are also different, so that the terminal device can preferentially reselect to a neighboring cell on a high-priority target frequency point, thereby improving the service quality of the terminal device.

Since the above-mentioned RRM measurement and cell reselection performed by the terminal equipment in the RRC idle state and RRC inactive state are the main sources of its power consumption, in order to ensure the communication performance of the terminal equipment, it can also effectively save the power consumption of the terminal equipment , the concept of relaxed RRM measurement has been introduced in the field of communication, but the solution for realizing relaxed RRM measurement has not been discussed yet.

Among them, the method and the device are conceived based on the same technology. Since the principle of solving the problem of the method and the device is similar, the implementation of the device and the method can be referred to each other, and the repetition will not be repeated.

Hereinafter, some terms used in this application are explained to facilitate the understanding of those skilled in the art.

1) A terminal device is a device that provides voice and/or data connectivity to users. The terminal device may also be called user equipment (user equipment, UE), mobile station (mobile station, MS), mobile terminal (mobile terminal, MT) and so on.

For example, the terminal device may be a handheld device with a wireless connection function, a vehicle-mounted device, and the like. At present, examples of some terminal devices are: mobile phone (mobile phone), tablet computer, notebook computer, palmtop computer, mobile internet device (mobile internet device, MID), wearable device, virtual reality (virtual reality, VR) device, enhanced Augmented reality (AR) equipment, wireless terminals in industrial control, wireless terminals in self driving, wireless terminals in remote medical surgery, smart grid Wireless terminals in transportation safety, wireless terminals in smart city, wireless terminals in smart home, etc.

2) The network device is the device that connects the terminal device to the wireless network in the communication system. As a node in the radio access network, a network device is, for example, a base station, and the network device may also be called a radio access network (radio access network, RAN) node (or device). The solution executed by the base station side in the embodiment of the present application may also be executed by other network devices, which is not limited in the embodiment of the present application.

Currently, examples of some base stations are: gNB, evolved Node B (evolved Node B, eNB), transmission reception point (transmission reception point, TRP), radio network controller (radio network controller, RNC), node B (Node B , NB), base station controller (base station controller, BSC), base transceiver station (basetransceiver station, BTS), home base station (for example, home evolved NodeB, or home Node B, HNB), or base band unit (base band unit, BBU) and so on.

In addition, in a network structure, the base station may include a centralized unit (centralized unit, CU) node and a distributed unit (distributed unit, DU) node. This structure separates the protocol layers of the eNB in the long term evolution (LTE) system. The functions of some protocol layers are centrally controlled by the CU, and the remaining part or all of the functions of the protocol layers are distributed in the DU. Centralized control of DUs.

3) The reference signal, which is sent by the base station through the cell it manages, is used to make the terminal equipment perform RRM measurement, so as to realize processes such as cell reselection, cell handover, and beam determination. Exemplarily, in the embodiment of the present application, the reference signal may be a synchronization signal block (synchronization signal block, SSB), a channel state information reference signal (channel state information-reference signal, CSI-RS) and the like.

4), signal quality, for the terminal equipment to perform RRM measurement on the cell, and the obtained measurement results can include one or more of the following signal quality parameters:

Signal amplitude (Srxlev, which can be represented by S _rxlev in subsequent descriptions), signal strength (Squal, which can be represented by S _qual in subsequent descriptions), reference signal received power (reference signal received power, RSRP), reference signal reception quality (reference signal received quality (RSRQ), signal to noise ratio (signal to noiseratio, SNR), signal to interference plus noise ratio (signal to interference plus noise ratio, SINR), etc.

5) The measurement configuration information of the cell is broadcast by the base station managing the cell through system messages (such as system information blocks (SIB2)), and is used for terminal devices accessing the cell to perform RRM measurement.

Among them, S _{nonintrasearch} P is used to indicate the signal amplitude threshold of inter-frequency/inter-system measurement (This specifies the Srxlev threshold(in dB)forNR inter-frequency and inter-RAT measurements), S _{nonintrasearch} Q is used to indicate inter-frequency/inter-RAT The signal strength threshold for system measurements (This specifies the Squal threshold(in dB) for NR inter-frequency and inter-RAT measurements). In the current measurement strategy, when the terminal equipment using this cell as the serving cell measures that the signal quality of the cell satisfies 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 When conditions are met, the terminal device performs measurement on neighboring cells on a high-priority target frequency point, an equal-priority target frequency point, and a low-priority target frequency point.

6) The target frequency point for cell measurement is configured by the base station to the terminal equipment. The terminal equipment measures the neighboring cells on the target frequency point, so as to perform cell reselection or handover according to the obtained measurement results.

According to the relationship between the target frequency point and the serving frequency point (that is, the frequency point where the serving cell of the terminal device is located), the target frequency points configured by the base station can be divided into two categories:

Same-frequency frequency point: the service frequency point.

Different frequency point: the target frequency point that is different from the service frequency point. Further, according to the relative relationship between the priority of different frequency points and the priority of service frequency points, different frequency points can be divided into three categories: high priority target frequency points, equal priority target frequency points, and low priority target frequency points. point. Among them, the high-priority target frequency point is a different-frequency frequency point with a priority higher than that of the service frequency point; the same-priority target frequency point is a different-frequency frequency point with the same priority as the service frequency point; the low-priority target frequency point The frequency point is an inter-frequency point with a priority lower than that of the service frequency point.

In addition, for the convenience of distinction and description, in this embodiment of the application, adjacent cells on the same frequency point are referred to as same-frequency adjacent cells, and adjacent cells on different frequency points are referred to as inter-frequency adjacent cells.

7) Cell measurement, including RRM measurement and radio link monitoring (radio link monitoring, RLM) measurement.

The character "/" generally indicates that the contextual objects are an "or" relationship.

It should be noted that a plurality referred to in this application refers to two or more than two.

In addition, it should be understood that in the description of this application, words such as "first" and "second" are only used for the purpose of distinguishing descriptions, and cannot be understood as indicating or implying relative importance, nor can they be understood as indicating or imply order.

The embodiments of the present application will be specifically described below in conjunction with the accompanying drawings.

Fig. 1 shows the architecture of a possible communication system to which the measurement method provided by the embodiment of the present application is applicable. Referring to Fig. 1, the communication system includes a base station and terminal equipment.

The base station provides wireless access-related services for the terminal equipment through the managed cell, and implements wireless physical layer functions, resource scheduling and wireless resource management, quality of service (Quality of Service, QoS) management, wireless access control, and Mobility management (such as cell reselection and handover) functions.

Wherein, each base station is responsible for managing at least one cell. As shown in the figure, 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 this communication system, each cell provides access services for terminal devices using spectrum resources of corresponding frequency points. It should be noted that the frequency points used by different cells may be the same or different. In addition, the present application does not limit the communication technology used by each cell, and the communication technologies used by different cells may be the same or different. Exemplarily, cell a-cell g are all LTE cells using 4G communication technology; or cell a-cell g are all NR cells using 5G communication technology; or some of the cells are LTE cells and some of the cells are NR cells.

The terminal device is a device that accesses a network through a cell managed by the base station.

The base station and the terminal device are connected through a Uu interface, so as to implement communication between the terminal device and the base station.

In addition, the architecture shown in Figure 1 can be applied to various communication scenarios, for example, the fifth generation (The 5thGeneration, 5G) communication system (also called new radio (new radio, NR) communication system), the future sixth Generation communication system and other communication systems evolved, long term evolution (Long Term Evolution, LTE) communication system, vehicle to everything (vehicle to everything, V2X), long term evolution-vehicle networking (LTE-vehicle, LTE-V), vehicle to everything Vehicle (vehicle to vehicle, V2V), Internet of Vehicles, Machine Type Communications (MTC), Internet of Things (IoT), Long Term Evolution - Machine to Machine (LTE-machine to machine, LTE-M), Machine to machine (machine to machine, M2M) and other communication scenarios.

In the communication system shown in Figure 1, due to the mobility of the terminal equipment, the terminal equipment can move from the coverage of one cell to the coverage of another cell, as shown in the figure, the terminal equipment moves from cell a to Cell b, therefore, the terminal device needs to continuously measure the cell and change the cell it resides in, so as to ensure the continuity of the service. In order to achieve the above goals, the terminal equipment needs to implement a process of cell reselection or cell handover.

In order to ensure that terminal equipment can achieve cell reselection or cell switching, the base station managing each cell broadcasts the measurement configuration information of the cell within the coverage of the cell it manages through system messages, and sends the target of the cell through system messages or RRC messages Frequency point configuration information. Wherein, the target frequency point configuration information includes target frequency points to be measured, and may also include adjacent cells to be measured on each target frequency point. In this way, after receiving the measurement configuration information of its serving cell and the target frequency point configuration information, the terminal device performs measurement on the neighboring cells on the target frequency point according to the measurement configuration information, and performs cell reselection or handover according to the measurement results .

In order to make the cell reselection or cell switching of the terminal equipment more flexible, the base station managing 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 value range of the priority of the frequency point is (0-7), and a larger value indicates a higher priority of the frequency point.

For example, cell 1 on frequency point 1 may have larger system bandwidth, better signal quality, or be able to provide higher transmission rate (such as a hotspot cell), and the base station managing cell 1 may set The priority of frequency point 1 is set to 7.

For another example, if the system bandwidth, signal quality, and transmission rate of the cell on frequency 2 are lower than those of the cell on frequency 1, then the base station managing cell 2 can prioritize frequency 2 in the measurement configuration information of cell 2. Level is set to 5.

For another example, the cell on frequency 3 may have a small system bandwidth, poor signal quality, or low transmission rate, so the base station managing cell 3 can set the priority of frequency 3 in the measurement configuration information of cell 3 for 3.

In this way, when the terminal device performs cell measurement, according to the relative relationship between the priority of each target frequency point and the priority of the service frequency point, the different frequency points in the target frequency points can be divided into three categories: high priority target frequency points , target frequencies of the same priority, and target frequencies of low priority.

It can be seen from the above description that the terminal device measures the neighboring cells on the low priority target frequency point and the same priority target frequency point to solve the cell coverage problem of the terminal device. As shown in FIG. 1 , cell a is the serving cell of the terminal device. When the terminal device moves to the edge of cell a, it initiates the measurement of adjacent cells (cell b, cell c, etc.) on such frequency points. In this way, when the terminal moves to the coverage of a neighboring cell on such a frequency point, the terminal device can reselect to a neighboring cell with better signal quality. The terminal device measures the neighboring cells on the high-priority target frequency points, hoping to reside in the neighboring cells of such frequency points, so as to obtain better services.

In order to take into account the cell coverage and service quality problems 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: under normal circumstances, when the terminal equipment determines that the signal quality of the serving cell is greater than that of the different frequency When measuring the threshold of different systems or different systems, only the adjacent cells on the high-priority target frequency point are measured; when the terminal device determines that the signal quality is not greater than the different-frequency/different system measurement threshold, the The same priority target frequency point and the neighboring cells on the low priority target frequency point are measured.

Since the cell measurement performed by the terminal equipment is also the source of power consumption of the terminal equipment, in order to ensure the communication performance of the terminal equipment and effectively save the power consumption of the terminal equipment, the concept of relaxed measurement has been introduced in the communication field. When performing relaxed measurement, the terminal device can reduce the measurement objects (for example, reduce the number of target frequency points, reduce the number of neighbor cells to be measured), or reduce the measurement frequency (for example, increase the detection delay T _detect , increase the measurement time delay T _measure , or increase the evaluation delay T _evaluate ), or do not perform cell measurement.

Embodiment one:

In order to enable the terminal device to flexibly perform relaxed measurement on neighboring cells on the target frequency point, so as to ensure the communication performance of the terminal device and save the power consumption of the terminal device, an embodiment of the present application provides a measurement method. The method can be adapted to the communication system shown in FIG. 1 . In the embodiment of the present application, the communication system uses the signal amplitude and signal strength to represent the signal quality as an example for specific description.

The terminal equipment saves the relaxation measurement threshold threshold _relaxmeasure . The relaxation measurement threshold threshold _relaxmeasure is used to judge whether to perform relaxation measurement. The relaxation measurement threshold threshold _relaxmeasure includes:

Same-frequency relaxation measurement threshold threshold _{intrarelaxmeasure} : same-frequency relaxation measurement signal amplitude threshold threshold _{intrarelaxmeasure} P, and same-frequency relaxation measurement signal strength threshold threshold _{intrarelaxmeasure} Q;

Inter-frequency relaxation measurement threshold threshold _{nonintrarelaxmeasure} : Inter-frequency relaxation measurement signal amplitude threshold threshold _{nonintrarelaxmeasure} P, and inter-frequency relaxation measurement signal strength threshold threshold _{nonintrarelaxmeasure} Q.

Wherein, the same-frequency relaxed measurement threshold threshold _{intrarelaxmeasure} is used to judge whether to perform relaxed measurement on the same-frequency neighboring cells. The inter-frequency relaxation measurement threshold _{nonintrarelaxmeasure} is used to determine whether to perform relaxation measurement on inter-frequency neighboring cells. Intra-frequency relaxation measurement signal amplitude threshold threshold _{intrarelaxmeasure} P is the signal amplitude critical value of the serving cell to judge whether to perform relaxation measurement on the same-frequency adjacent cell _; The signal strength critical value of the serving cell for relaxed measurement; the threshold _{nonintrarelaxmeasure} P is the signal amplitude critical value of the serving cell for judging whether to perform relaxed measurement on inter-frequency neighboring cells; the inter-frequency relaxed measurement signal strength Threshold threshold _{nonintrarelaxmeasure} Q is the signal strength critical value of the serving cell for judging whether to perform relaxed measurement on inter-frequency neighboring cells.

In addition, the intra-frequency relaxation measurement threshold threshold _{intrarelaxmeasure} is greater than a preset threshold standard initial value (subsequently represented by threshold Criterion S), and smaller than the intra-frequency measurement threshold S _intrasearch in the measurement configuration information of the serving cell. Specifically, threshold standard initial value threshold Criterion S< same-frequency relaxation measurement signal amplitude threshold threshold _{intrarelaxmeasure} P< same-frequency measurement signal amplitude threshold S _intrasearch P; threshold standard initial value threshold Criterion S< same-frequency relaxation measurement signal strength Threshold threshold _{intrarelaxmeasure} Q< same frequency measurement signal strength threshold S _intrasearch Q.

The inter-frequency relaxation measurement threshold threshold _{nonintrarelaxmeasure} is greater than the preset threshold standard initial value (subsequently represented by threshold Criterion S), and smaller than the inter-frequency/inter-system measurement threshold S _{nonintrasearch} in the measurement configuration information of the serving cell. Specifically, the threshold standard initial value threshold Criterion S < inter-frequency relaxation measurement signal amplitude threshold threshold _{nonintrarelaxmeasure} P < inter-frequency measurement signal amplitude threshold S _{nonintrasearch} P; threshold standard initial value threshold Criterion S < inter-frequency relaxation measurement signal strength Threshold threshold _{nonintrarelaxmeasure} Q<inter-frequency measurement signal strength threshold S _{nonintrasearch} Q.

Wherein, the threshold criterion initial value threshold Criterion S is: measurement access threshold. That is, the terminal device can only measure signals whose signal quality is higher than the initial value threshold Criterion S of the threshold standard. When the signal quality of the signal is lower than the threshold Criterion S, the terminal device cannot measure the signal.

The same-frequency relaxation measurement threshold threshold _{intrarelaxmeasure} satisfies the above-mentioned conditions, and when the signal quality of the serving cell is within the range between the same-frequency relaxation measurement threshold threshold _{intrarelaxmeasure} and the same-frequency measurement threshold S _intrasearch , the relaxation measurement is performed on the same-frequency adjacent cell Otherwise, if the same-frequency relaxed measurement threshold threshold _{intrarelaxmeasure} is set lower than the threshold standard initial value threshold Criterion S, it will cause the terminal device to start to relax the same-frequency adjacent cell as long as it measures the signal of the serving cell, causing the terminal When the signal quality of the serving cell is poor, the device cannot switch to the same-frequency neighbor cell in time.

The inter-frequency relaxation measurement threshold threshold _{nonintrarelaxmeasure} satisfies the above conditions, and when the signal quality of the serving cell is within the range between the inter-frequency relaxation measurement threshold threshold _{nonintrarelaxmeasure} and the inter-frequency/inter-system measurement threshold S _{nonintrasearch} , the inter-frequency neighbor cell Execute relaxed measurement; otherwise, if the threshold _{nonintrarelaxmeasure} is set to be lower than the threshold standard initial value threshold Criterion S, the terminal device will start to perform relaxed measurement on inter-frequency neighboring cells as long as it measures the signal of the serving cell , causing the terminal equipment to fail to switch to the inter-frequency neighbor cell in time when the signal quality of the serving cell is poor; and if the inter-frequency relaxation measurement threshold threshold _{nonintrarelaxmeasure is set} higher than the inter-frequency/inter-system measurement threshold S _{nonintrasearch} , when In the scenario where the signal quality of the serving cell exceeds the inter-frequency/inter-system measurement threshold S _{nonintrasearch} , the terminal device will have a logical conflict between performing relaxed measurement on inter-frequency neighboring cells or not measuring neighboring cells on non-high-priority target frequency points.

In the embodiment of this application, the terminal device's relaxed measurement trigger mechanism for co-frequency adjacent cells is as follows:

Mode 1: When the terminal device determines that the signal amplitude S _rxlev of the signal quality of the serving cell > the same-frequency relaxation measurement signal amplitude threshold threshold _{intrarelaxmeasure} P, and the signal strength S _qual of the serving cell > the same-frequency relaxation measurement signal strength threshold threshold _{intrarelaxmeasure} Q, the terminal device performs relaxation measurement on intra-frequency neighboring cells, as shown in FIG. 2A .

Correspondingly, when the terminal device determines the signal quality of the serving cell, the signal amplitude S _rxlev ≤ the intrarelaxmeasure signal amplitude threshold threshold _{intrarelaxmeasure} P, and/or, the signal strength S _qual of the serving cell ≤ the intrarelaxmeasure signal Intensity threshold threshold _{intrarelaxmeasure} Q, the terminal device performs normal measurement on co-frequency neighboring cells.

Method 2: When the terminal device determines that the signal amplitude S _rxlev of the signal quality of the serving cell > the same-frequency relaxation measurement signal amplitude threshold threshold _{intrarelaxmeasure} P, or the signal strength S _qual of the serving cell > the same-frequency relaxation measurement signal strength threshold threshold _{intrarelaxmeasure} Q, the terminal device performs relaxation measurement on intra-frequency neighboring cells.

Correspondingly, when the terminal device determines that the signal amplitude S _rxlev in the signal quality of the serving cell ≤ the same-frequency relaxation measurement signal amplitude threshold threshold _{intrarelaxmeasure} P, and the serving cell's signal strength S _qual ≤ the same-frequency relaxation measurement signal strength threshold threshold _{intrarelaxmeasure} Q, the terminal device performs normal measurement on intra-frequency neighboring cells.

In one design, the terminal device may perform relaxed measurement on the same-frequency neighboring cells by reducing the measurement frequency of the same-frequency neighboring cells and/or reducing the number of same-frequency neighboring cells (until the cell measurement is not performed).

For example, the terminal device may use a relaxed intra-frequency measurement period T intrarelax that is greater than a normal _intra -frequency measurement period T _intrarelax to perform relaxed measurements on intra-frequency neighboring cells. Optionally, T _intrarelax =T _intra *A1, where A1>1. Wherein, the normal same-frequency measurement period T _intra is a measurement period used by the terminal device to perform normal measurement on the same-frequency neighboring cells, and the normal measurement is, for example, no relaxed measurement.

For another example, the terminal device reduces the number of co-frequency adjacent cells from B0 to B1, where both B0 and B1 are integers greater than 0, and B1<B0. Optionally, B1=B0/A2, A2>1.

In the embodiment of this application, the terminal device's relaxed measurement trigger mechanism for inter-frequency neighboring cells is as follows:

Mode 1: When the terminal device determines that the signal amplitude S _rxlev in the signal quality of the serving cell > inter-frequency relaxation measurement signal amplitude threshold threshold _{nonintrarelaxmeasure} P, and the signal strength S _qual > threshold _{nonintrarelaxmeasure} Q of the serving cell, the terminal device Relaxed measurement is performed on inter-frequency adjacent cells on the target frequency point, as shown in Figure 2B.

When the terminal device determines the signal quality of the serving cell, the signal amplitude S _rxlev ≤ the signal amplitude threshold _{nonintrarelaxmeasure} P for inter-frequency relaxation measurement, and/or, the signal strength S _qual of the serving cell ≤ the signal strength threshold nonintrarelaxmeasure P for inter-frequency relaxation measurement _{nonintrarelaxmeasure} Q, the terminal device performs normal measurement on all target frequency points (including high-priority target frequency points, equal-priority target frequency points, and low-priority target frequency points).

Mode 2: When the terminal device determines that the signal amplitude S _rxlev in the signal quality of the serving cell > inter-frequency relaxation measurement signal amplitude threshold threshold _{nonintrarelaxmeasure} P, or the signal strength S _qual > threshold _{nonintrarelaxmeasure} Q of the serving cell, the terminal device Perform relaxation measurement on inter-frequency adjacent cells on the target frequency point.

When the terminal device determines that the signal amplitude S _rxlev in the signal quality of the serving cell ≤ threshold _{nonintrarelaxmeasure} P, and the signal strength S _qual of the serving cell ≤ threshold _{nonintrarelaxmeasure} Q, The terminal device performs normal measurement on all target frequency points (including high priority target frequency points, equal priority target frequency points, and low priority target frequency points).

In one design, the terminal device may perform relaxed measurement on inter-frequency adjacent cells by reducing the measurement frequency of inter-frequency adjacent cells and/or reducing the number of inter-frequency frequency points.

For example, the terminal device may use a relaxed inter-frequency measurement period T _{nonintrarelax that is} greater than a normal inter-frequency measurement period T _nonintra to perform relaxed measurements on inter-frequency neighboring cells. Optionally, T _{nonintrarelax} =T _nonintra *A3, A3>1. Wherein, the normal inter-frequency measurement period T _nonintra is a measurement period used by the terminal device to perform normal measurement on inter-frequency adjacent cells.

For another example, the terminal device reduces the number of inter-frequency frequency points from N0 to N1, where both N0 and N1 are integers greater than 0, and N1<N0. Optionally, N1=N0/A4, A4>1.

It should also be noted that, in the above method 1 and method 2, the terminal device can also determine that all types of _inter -frequency frequency point Whether to perform relaxed measurement on neighboring cells with different frequencies, or only perform relaxed measurement on neighboring cells on high-priority target frequency points. The specific judgment mechanism is as follows:

When the inter-frequency relaxation measurement signal amplitude threshold threshold _{nonintrarelaxmeasure} P<the signal amplitude S _rxlev in the signal quality of the serving cell ≤ the inter-frequency/inter-system measurement signal amplitude threshold S _{nonintrasearch} P, and/or the inter-frequency relaxation measurement signal The strength threshold threshold _{nonintrarelaxmeasure} Q<signal strength S _qual in the signal quality of the serving cell ≤ the inter-frequency/inter-system measurement signal strength threshold S _{nonintrasearch} Q, that is, when the terminal device needs to measure all types of inter-frequency points, the The above-mentioned terminal equipment performs relaxed measurement on inter-frequency neighboring cells on all types of inter-frequency frequency points (including high priority target frequency points, equal priority target frequency points, and low priority target frequency points).

When the signal amplitude S _rxlev in the signal quality of the serving cell > the inter-frequency/inter-system measurement signal amplitude threshold S _{nonintrasearch} P, and the signal strength S _qual in the signal quality of the serving cell > the inter-frequency/inter-system measurement signal When the strength threshold S _{is nonintrasearch} Q, that is, when the terminal device only needs to measure high-priority target frequency points, and does not measure the same priority target frequency points and low-priority target frequency points, the terminal device only needs to measure The inter-frequency neighbor cells on the high-priority target frequency point perform relaxed measurement.

It should be noted that, in the embodiment of the present application, the relaxed measurement threshold threshold _relaxmeasure is configured by the base station to the terminal device. For example, the communication system may design a new structure of RRC signaling, and the base station may set the threshold _relaxmeasure carried in the RRC signaling. For another example, the base station may add a new field to the system message SIB2, and include the relaxed measurement threshold threshold _relaxmeasure in this field. The relaxation measurement threshold threshold _relaxmeasure may also be specified by a protocol and stored in the terminal device. The threshold _relaxmeasure may also be calculated by the base station or the terminal device according to a calculation method defined in the protocol and stored in the terminal device, or calculated by a calculation method configured by the base station to the terminal device. The relaxed measurement threshold threshold _relaxmeasure may also be selected by the terminal device from multiple threshold candidate values, where the multiple threshold candidate values may be specified by the protocol and stored in the terminal device, or It is configured for the terminal equipment by the base station. For example, the terminal device may select the relaxed measurement threshold threshold _relaxmeasure according to at least one or a combination of the following: service priority of the terminal device, service frequency point priority, and mobility information of the terminal device.

The higher the service priority of the terminal device is, the greater the value of the relaxation measurement threshold threshold _relaxmeasure selected by the terminal device is. In this way, the relaxed measurement threshold is increased when the terminal device performs critical services, so that the terminal device does not perform relaxed measurement as much as possible, thereby ensuring the communication performance of the terminal device.

The higher the priority of the service frequency point of the terminal device (good data transmission rate of the serving cell, good network coverage, etc.), it means that the serving cell can provide a higher quality of service for the terminal device, and the relaxed measurement threshold threshold selected by the terminal device The smaller the value of _{relaxmeasure is} . In this way, the terminal device enters the relaxed measurement mode as soon as possible, thereby reducing the power consumption of the terminal device.

When the mobile information of the terminal device indicates that the terminal device is not at the edge of cell coverage, and/or the terminal device moves at a low speed, it means that the serving cell can provide the terminal device with a high quality of service, and the relaxed measurement threshold selected by the terminal device The smaller the threshold _relaxmeasure value is. In this way, the terminal device enters the relaxed measurement mode as soon as possible, thereby reducing the power consumption of the terminal device.

Exemplarily, each parameter in the relaxation measurement threshold threshold _relaxmeasure conforms to the following formulas 1 to 4 respectively:

threshold _{intrarelaxmeasure} P＝k1*(S _intrasearch P-threshold Criterion S)+threshold Criterion S Formula 1

threshold _{intrarelaxmeasure} Q＝k2*(S _intrasearch Q-threshold Criterion S)+threshold Criterion S Formula 2

threshold _{nonintrarelaxmeasure} P＝k3*(S _{nonintrasearch} P-threshold Criterion S)+threshold Criterion S Formula 3

threshold _{nonintrarelaxmeasure} Q＝k4*(S _{nonintrasearch} Q-threshold Criterion S)+threshold Criterion S Formula 4

Wherein, 0<k1<1, 0<k2<1, 0<k3<1, 0<k4<1 in the above formula, k1 to k4 may be the same or different. In addition, the value of k1-k4 in the above formula may be determined by the base station and configured to the terminal device, or specified by the protocol and stored in the terminal device, or determined by the terminal device itself.

In one design, the terminal device or the base station may determine the value of k1-k4 according to at least one or a combination of the following: the service priority of the terminal device, the service frequency point priority, the mobility information. Wherein, the mobility information of the terminal device may include, but is not limited to, location information and moving speed of the terminal device. In this way, the terminal device or the base station can dynamically adjust the relaxed measurement threshold according to the current network status.

Exemplarily, when the service priority of the terminal device is higher, the value of k1-k4 set by the terminal device or the base station is larger, thus, the value of the relaxed measurement threshold obtained according to k1-k4 is also larger. In this way, the relaxed measurement threshold is increased when the terminal device performs critical services, so that the terminal device does not perform relaxed measurement as much as possible, thereby ensuring the communication performance of the terminal device.

Exemplarily, when the priority of the service frequency point is higher, the value of k1-k4 set by the terminal device or the base station is lower, so that the value of the relaxed measurement threshold obtained according to k1-k4 is also lower. Since the higher the priority of the service frequency point, it means that the serving cell can provide higher service quality for the terminal equipment, and the demand for cell reselection or handover of the terminal equipment is lower. The relaxed measurement threshold threshold _relaxmeasure is set to a smaller value, so that the terminal device enters the relaxed measurement mode as soon as possible, thereby reducing the power consumption of the terminal device.

Exemplarily, when the mobile information of the terminal device indicates that the terminal device is not at the edge of cell coverage, and/or the moving speed of the terminal device is low, the terminal device or the base station sets the value of k1-k4 to be lower, so that , the value of the relaxation measurement threshold obtained according to k1-k4 is also lower. The mobile information of the terminal device indicates that the terminal device is not at the edge of cell coverage and the moving speed of the terminal device is relatively low, both of which indicate that the serving cell can provide the terminal device with a higher quality of service. The relaxed measurement threshold threshold _relaxmeasure is set to a smaller value, so that the terminal device enters the relaxed measurement mode as soon as possible, thereby reducing the power consumption of the terminal device.

Exemplarily, the code of SIB2 carrying the relaxation measurement threshold threshold _relaxmeasure is as follows:

Among them, the underlined codes in the above codes are the relaxation measurement thresholds: " threshnonIntraRelaxMeasureP " represents the threshold _{nonintrarelaxmeasure} P of the amplitude threshold of the inter-frequency relaxation measurement signal; " threshnonIntraRelaxMeasureQ " represents the threshold _{nonintrarelaxmeasure} Q of the inter -frequency relaxation measurement signal strength; Intra-frequency relaxation measurement signal amplitude threshold threshold _{intrarelaxmeasure} P; " threshIntraRelaxMeasureQ " represents the same-frequency relaxation measurement signal strength threshold threshold _{intrarelaxmeasure} Q.

An embodiment of the present application provides a measurement method, in which a terminal device can determine whether to perform relaxed measurement on neighboring cells on a target frequency point by relaxing a measurement threshold. Therefore, the communication system can flexibly set the relaxed measurement threshold, so that the terminal device can flexibly perform relaxed measurement on the adjacent cells on the target frequency point, so as to ensure the communication performance of the terminal device and save the power consumption of the terminal device .

Embodiment two:

In order to enable the terminal device to flexibly perform relaxed measurement on neighboring cells on the target frequency point, so as to ensure the communication performance of the terminal device and save the power consumption of the terminal device, an embodiment of the present application provides a measurement method. The method can be adapted to the communication system shown in FIG. 1 . In the embodiment of the present application, the communication system uses the signal amplitude and signal strength to represent the signal quality as an example for specific description.

The terminal equipment saves the relaxation measurement threshold threshold _relaxmeasure . Wherein, in this embodiment of the present application, the parameters contained in the relaxed measurement threshold threshold _relaxmeasure and the values of each parameter, and the method for the terminal device to obtain the relaxed measurement threshold threshold _relaxmeasure may refer to the description in Embodiment 1. , which will not be repeated here.

The terminal device also saves a plurality of same-frequency measurement signal quality ranges, so that according to the strength of the signal quality of the serving cell, the relaxation measurement of different relaxation levels is performed on the same-frequency adjacent cells, and finally the differentiated relaxation measurement is realized, and the relaxation measurement is further improved. flexibility. Wherein, each same-frequency measurement signal quality range corresponds to a different same-frequency relaxation level, and the larger the value contained in the same-frequency measurement signal quality range, the greater the corresponding same-frequency relaxation level, as shown in FIG. 2C . The greater the co-frequency relaxation level, the lower the measurement frequency of the same-frequency neighboring cells by the terminal device or the smaller the number of co-frequency neighboring cells. In other words, the co-frequency relaxation level corresponds to the power consumption of the terminal device, and the co-frequency relaxation level The larger the terminal device, the lower the power consumption.

Therefore, when the terminal device determines that the signal quality of the serving cell is greater than the same-frequency relaxed measurement threshold threshold _{intrarelaxmeasure} in the relaxed measurement threshold threshold _relaxmeasure (for the specific process, refer to the description in Embodiment 1), the terminal device may perform the following steps , according to the strength of the signal quality of the serving cell, differential relaxation measurement is performed on the adjacent cells of the same frequency:

When the terminal device determines that the signal quality of the serving cell is within the first same-frequency measurement signal quality range, the terminal device performs the _{B1_1} same-frequency Neighborhoods are measured. That is, the terminal device uses the same-frequency relaxation level 1 to perform relaxed measurement on the same-frequency neighboring cells.

When the terminal device determines that the signal quality of the serving cell is within the second intra-frequency measurement signal quality range, the terminal device performs the B1_2 intra-frequency measurement on the serving frequency according to the second relaxed intra-frequency measurement cycle T _{intrarelax_2} Neighborhoods are measured. That is, the terminal device uses the same-frequency relaxation level 2 to perform relaxed measurement on the same-frequency neighboring cells.

Wherein, any value within the quality range of the second co-frequency measurement signal is greater than the value within the quality range of the first co-frequency measurement signal, T _{intrarelax_2} >T _{intrarelax_1} and/or B1_2<B1_1, both B1_2 and B1_1 are greater than Integer of 0. Exemplarily, T _{intrarelax_2} =T _{intrarelax_1} *A5, B1_2=B1_1/A6, A5>1, A6>1. The same frequency relaxation level 2 is higher than the same frequency relaxation level 1.

Wherein, the multiple intra-frequency measurement signal quality ranges are determined according to an intra-frequency relaxation measurement threshold threshold _{intrarelaxmeasure} and at least one intra-frequency relaxation level threshold. Wherein, the first co-frequency measurement signal quality range corresponding to the first co-frequency relaxation level is (co-frequency relaxation measurement threshold threshold _{intrarelaxmeasure} , the first co-frequency relaxation level threshold]; the second co-frequency measurement corresponding to the second co-frequency relaxation level The signal quality range is (the first co-frequency relaxation level threshold, the second co-frequency relaxation level threshold]; ... The Lth co-frequency measurement signal quality range corresponding to the L co-frequency relaxation level is (L-1 co-frequency relaxation level Threshold, +∞].

In one design, each intra-frequency relaxation level threshold is determined according to an intra-frequency relaxation measurement threshold threshold _{intrarelaxmeasure} .

For example, the first intra-frequency relaxation level threshold=intra-frequency relaxation measurement threshold threshold _{intrarelaxmeasure} *j, where j>1.

Specifically, the first intrarelaxlevel signal amplitude threshold threshold _{intrarelaxlevel_1} P=intrarelaxmeasure signal amplitude threshold threshold _{intrarelaxmeasure} P*j. The second same-frequency relaxation level signal amplitude threshold threshold _{intrarelaxlevel_2} P=the same-frequency relaxation measurement signal amplitude threshold threshold _{intrarelaxmeasure} P*j ² . The signal amplitude threshold of the L-1th same-frequency relaxation level threshold _{intrarelaxlevel_L-1} P=the signal amplitude threshold of the same-frequency relaxation measurement signal threshold _{intrarelaxmeasure} P*j ^L-1 .

The first intrarelax level signal strength threshold threshold _{intrarelaxlevel_1} Q=intrarelaxmeasure signal strength threshold threshold _{intrarelaxmeasure} Q*j. The second intrarelax level signal strength threshold threshold _{intrarelaxlevel_2} Q=intrarelaxmeasure signal strength threshold _{intrarelaxmeasure} Q*j ² . The L-1th intrarelaxlevel signal amplitude threshold threshold _{intrarelaxlevel_L-1} Q=intrarelaxmeasure signal strength threshold _{intrarelaxmeasure} Q*j ^L-1 .

Wherein, the value of j may be calculated by the base station through a set calculation method and configured for the terminal device, or calculated by the terminal device according to a set calculation method. For example, the base station or the terminal device may calculate the value of j according to at least one or a combination of the following: service priority of the terminal device, service frequency point priority, and mobility information of the terminal device. In this way, the terminal device or the base station can dynamically adjust the relaxed measurement threshold according to the current network status.

For example, when the service priority of the terminal device is lower and the service frequency point priority is higher, or the mobility information of the terminal device indicates that the terminal device is closer to the center of the serving cell and/or the terminal device moves at a lower speed, The smaller the j value is set. In this way, when the terminal equipment has low demand for cell reselection or handover, it can enter the relaxed measurement mode as soon as possible, thereby reducing the power consumption of the terminal equipment.

In another design, each intra-frequency relaxation level threshold is configured by the base station for the terminal device, or specified by a protocol and stored in the terminal device.

The terminal device also saves a plurality of different frequency measurement signal quality ranges, so that according to the strength of the signal quality of the serving cell, the relaxation measurement of different relaxation levels is performed on the inter-frequency adjacent cells, and finally the differentiated relaxation measurement is realized, and the relaxation measurement is further improved. flexibility. Wherein, each inter-frequency measurement signal quality range corresponds to a different inter-frequency relaxation level, and the larger the value contained in the inter-frequency measurement signal quality range, the greater the corresponding inter-frequency relaxation level, as shown in FIG. 2D . The greater the inter-frequency relaxation level, the lower the measurement frequency of inter-frequency adjacent cells by the terminal device or the smaller the number of inter-frequency adjacent cells. In other words, the inter-frequency relaxation level corresponds to the power consumption of the terminal device, and the inter-frequency relaxation level The larger the terminal device, the lower the power consumption.

Therefore, when the terminal device determines that the signal quality of the serving cell is greater than the inter-frequency relaxation measurement threshold threshold _{nonintrarelaxmeasure} in the relaxed measurement threshold threshold _relaxmeasure (for the specific process, refer to the description in Embodiment 1), the terminal device may perform the following steps , according to the strength of the signal quality of the serving cell, differential relaxation measurement is performed on the inter-frequency adjacent cells:

When the terminal device determines that the signal quality of the serving cell is within the first inter-frequency measurement signal quality range, the terminal device performs N1_1 inter-frequency measurements on the inter-frequency point according to the first relaxed inter-frequency measurement period T _{nonintrarelax_1} Neighborhoods are measured. That is, the terminal device uses inter-frequency relaxation level 1 to perform relaxed measurement on inter-frequency adjacent cells.

When the terminal device determines that the signal quality of the serving cell is within the second inter-frequency measurement signal quality range, the terminal device performs N1_2 inter-frequency measurements on the serving frequency according to the second relaxed inter-frequency measurement period T _{nonintrarelax_2} Neighborhoods are measured. That is, the terminal device uses inter-frequency relaxation level 2 to perform relaxed measurement on inter-frequency neighboring cells.

Wherein, any value in the second inter-frequency measurement signal quality range is greater than the value in the first inter-frequency measurement signal quality range, T _{nonintrarelax_2} >T _{nonintrarelax_1} and/or N1_2<N1_1, N1_2 and N1_1 are both greater than Integer of 0. Exemplarily, T _{nonintrarelax_2} =T _{nonintrarelax_1} *A7, N1_2=N1_1/A8, A7>1, A8>1. Interval Relaxation Level 2 is higher than Interfrequency Relaxation Level 1.

Wherein, the plurality of inter-frequency measurement signal quality ranges are determined according to an inter-frequency relaxation measurement threshold _{nonintrarelaxmeasure} and at least one inter-frequency relaxation level threshold. Wherein, the first inter-frequency measurement signal quality range corresponding to the first inter-frequency relaxation level is (inter-frequency relaxation measurement threshold threshold _{nonintrarelaxmeasure} , the first inter-frequency relaxation level threshold]; the second inter-frequency measurement corresponding to the second inter-frequency relaxation level The signal quality range is (the first inter-frequency relaxation level threshold, the second inter-frequency relaxation level threshold]; ... The L-th inter-frequency measurement signal quality range corresponding to the L-th inter-frequency relaxation level is (the L-1st inter-frequency relaxation level Threshold, +∞].

In one design, each inter-frequency relaxation level threshold is determined according to an inter-frequency relaxation measurement threshold threshold _{intrarelaxmeasure} .

For example, the first inter-frequency relaxation level threshold=inter-frequency relaxation measurement threshold threshold _{nonintrarelaxmeasure} *j, where j>1.

Specifically, the first inter-frequency relaxation level signal amplitude threshold threshold _{nonintrarelaxlevel_1} P=inter-frequency relaxation measurement signal amplitude threshold threshold _{nonintrarelaxmeasure} P*j. The second inter-frequency relaxation level signal amplitude threshold threshold _{nonintrarelaxlevel_2} P=inter-frequency relaxation measurement signal amplitude threshold threshold _{nonintrarelaxmeasure} P j ² . The L-1th inter-frequency relaxation level signal amplitude threshold threshold _{nonintrarelaxlevel_L-1} P=inter-frequency relaxation measurement signal amplitude threshold threshold _{nonintrarelaxmeasure} P j ^L-1 .

The first inter-frequency relaxation level signal strength threshold threshold _{nonintrarelaxlevel_1} Q=inter-frequency relaxation measurement signal strength threshold threshold _{nonintrarelaxmeasure} Q*j. The second inter-frequency relaxation level signal strength threshold threshold _{nonintrarelaxlevel_2} Q=inter-frequency relaxation measurement signal strength threshold threshold _{nonintrarelaxmeasure} Q j ² . The L-1th inter-frequency relaxation level signal amplitude threshold threshold _{nonintrarelaxlevel_L-1} Q=inter-frequency relaxation measurement signal strength threshold threshold _{nonintrarelaxmeasure} Q j ^L-1 .

Wherein, the value of j may be calculated by the base station through a set calculation method and configured for the terminal device, or calculated by the terminal device according to a set calculation method. For example, the base station or the terminal device may calculate the value of j according to at least one or a combination of the following: service priority of the terminal device, service frequency point priority, and mobility information of the terminal device. For the value selection rules of j, refer to the above value selection rules when calculating the same-frequency relaxation level signal strength threshold, and will not be repeated here.

Embodiment four:

In order to enable the terminal device to flexibly perform relaxed measurement on neighboring cells on the target frequency point, so as to ensure the communication performance of the terminal device and save the power consumption of the terminal device, an embodiment of the present application provides a measurement method. The method can be adapted to the communication system shown in FIG. 1 . The method will be described in detail below with reference to FIG. 3 .

S301: Each base station in the communication system sends measurement configuration information for a managed cell through a system message. The measurement configuration information of any cell includes the priority of the frequency point where the cell is located, the intra-frequency measurement threshold S _intrasearch and the inter-frequency/inter-system measurement threshold S _{nonintrasearch} . For the managed cell, each base station sends the cell's target frequency point configuration information through a system message or an RRC message. Wherein, the target frequency point configuration information includes target frequency points to be measured, and may also include adjacent cells to be measured on each target frequency point.

The terminal device receives the measurement configuration information and the target frequency point configuration information of its serving cell, and determines the priority of the serving frequency point, the intra-frequency measurement threshold S _intrasearch and the inter-frequency/inter-system measurement threshold S _{nonintrasearch} , and the target frequency point. In addition, after receiving the measurement configuration information of the neighboring cell, the terminal device determines the priority of each target frequency point.

The terminal device may classify the target frequency point into at least one of two types according to the relationship between the target frequency point and the service frequency point: same frequency point and different frequency point.

Further, according to the relative relationship between the priority of each target frequency point and the priority of the service frequency point, the terminal device divides different frequency points into three categories: high priority target frequency points, equal priority target frequency points, Low priority target frequency point.

S302: The terminal device determines the intra-frequency relaxation measurement threshold threshold intrarelaxmeasure according to the intra-frequency measurement threshold S _intrasearch in the serving cell and the preset threshold standard initial value threshold Criterion S, so as to ensure the _intra -frequency relaxation measurement threshold threshold _{intrarelaxmeasure} greater than the initial value thresholdCriterion S of the threshold standard, and less than the same-frequency measurement threshold S _intrasearch in the measurement configuration information of the serving cell _; The threshold standard initial value thresholdCriterion S, determine the inter-frequency relaxation measurement threshold threshold _{nonintrarelaxmeasure} , so as to ensure that the inter-frequency relaxation measurement threshold threshold _{nonintrarelaxmeasure} is greater than the threshold standard initial value threshold Criterion S, and smaller than the measurement configuration information of the serving cell Inter-frequency/inter-system measurement threshold S _{nonintrasearch} .

In one design, the terminal device may determine the intra-frequency relaxation measurement signal amplitude threshold threshold _{intrarelaxmeasure} P and the intra-frequency relaxation measurement in the intra-frequency measurement threshold S _intrasearch according to Formula 1 and Formula 2 in Embodiment 1 Signal strength threshold threshold _{intrarelaxmeasure} Q.

The terminal device may determine the _inter -frequency relaxation measurement signal amplitude threshold threshold _{nonintrarelaxmeasure} P and the inter-frequency relaxation measurement signal strength threshold threshold _{nonintrarelaxmeasure} in the inter-frequency relaxation measurement threshold threshold nonintrarelaxmeasure according to Formula 3 and Formula 4 in Embodiment 1 Q.

Wherein, the calculation methods corresponding to Formulas 1 to 4 may be specified by the protocol and stored in the terminal device, or configured by the base station for the terminal device.

In one design, the base station may also carry multiple candidate values of the intra-frequency relaxed measurement threshold and multiple candidate values of the inter-frequency relaxed measurement threshold in the measurement configuration information. Wherein, the same-frequency relaxation measurement signal amplitude threshold P candidate value and the same-frequency relaxation measurement signal strength threshold Q candidate value in each same-frequency relaxation measurement threshold candidate value conform to the formula 1 and the formula in the first embodiment respectively two. The inter-frequency relaxation measurement signal amplitude threshold P candidate value and the inter-frequency relaxation measurement signal strength threshold Q candidate value in each of the inter-frequency relaxation measurement threshold candidate values respectively comply with formula 3 and formula 4 of the first embodiment.

The terminal device may select the intra-frequency relaxation measurement threshold threshold intrarelaxmeasure from the multiple intra-frequency relaxation measurement threshold candidate values, and select the _inter -frequency relaxation measurement threshold threshold _{nonintrarelaxmeasure} from the multiple inter-frequency relaxation measurement threshold candidate values. For example, the terminal device may be selected randomly, or selected according to one or a combination of the following: service priority of the terminal device, service frequency point priority, and mobility information of the terminal device. For the specific process, reference may be made to the description in Embodiment 1, which will not be repeated here.

S303: The terminal device can perform relaxed measurement on the same-frequency neighboring cells on the same-frequency frequency point according to the same-frequency relaxed measurement threshold threshold _{intrarelaxmeasure ;} Take a relaxation measurement. For the specific process, reference may be made to the specific descriptions in Embodiment 1 to Embodiment 3, which will not be repeated here.

For example, when the service priority of the terminal device increases, the values of the intra-frequency relaxation measurement threshold threshold _{intrarelaxmeasure} and the inter-frequency relaxation measurement threshold threshold _{nonintrarelaxmeasure} are increased. In this way, the relaxed measurement threshold is increased when the terminal device performs critical services, so that the terminal device does not perform relaxed measurement as much as possible, thereby ensuring the communication performance of the terminal device.

For another example, when the priority of the service frequency point increases, or the mobile information of the terminal device indicates that the terminal device is closer to the cell coverage center and/or the mobile speed of the terminal device is lower, the intra-frequency relaxation measurement threshold threshold _{intrarelaxmeasure} , and the value of the inter-frequency relaxation measurement threshold threshold _{nonintrarelaxmeasure} is lowered. In this way, when the cell reselection or handover requirement of the terminal equipment decreases, the relaxed measurement threshold is lowered, so that the terminal equipment enters the relaxed measurement mode as soon as possible, thereby reducing the power consumption of the terminal equipment.

S305: The terminal device may perform relaxed measurement on the same-frequency neighboring cells on the same-frequency frequency point according to the adjusted _{intra-frequency relaxed measurement threshold threshold intrarelaxmeasure ;} Perform relaxed measurements on inter-frequency adjacent cells.

It should be noted that the above S304 and S305 are optional steps, and the communication system may adjust the same-frequency relaxation measurement threshold threshold _{intrarelaxmeasure} and the inter-frequency relaxation measurement threshold _{nonintrarelaxmeasure} by the terminal device.

An embodiment of the present application provides a measurement method, in which a terminal device can determine whether to perform relaxed measurement on neighboring cells on a target frequency point by relaxing a measurement threshold. Therefore, the communication system can flexibly set the relaxed measurement threshold, so that the terminal device can flexibly perform relaxed measurement on the adjacent cells on the target frequency point, so as to ensure the communication performance of the terminal device and save the power consumption of the terminal device .

S403: The base station may also adjust the intra-frequency relaxation measurement threshold threshold _{intrarelaxmeasure} and the inter-frequency relaxation measurement threshold threshold _{nonintrarelaxmeasure} according to the following one or a combination: the service priority of the terminal device, the service frequency point priority, the Describe the mobility information of the terminal device. Then, the base station sends measurement adjustment information to the terminal device, where the measurement adjustment information includes the adjusted intra-frequency relaxed measurement threshold threshold _{intrarelaxmeasure} and the adjusted inter-frequency relaxed measurement threshold _{nonintrarelaxmeasure} . For specific adjustment rules, reference may be made to the description in S304 of Embodiment 4, which will not be repeated here. The relaxed measurement threshold sent by the base station to the terminal device may be the threshold before adjustment, or the threshold after adjustment.

S404: The terminal device may also adjust the intra-frequency relaxation measurement threshold threshold _{intrarelaxmeasure} and the inter-frequency relaxation measurement threshold threshold _{nonintrarelaxmeasure} according to the following one or a combination: the service priority of the terminal device, the service frequency point priority, Mobility information of the terminal device. For specific adjustment rules, reference may be made to the description in S304 of Embodiment 4, which will not be repeated here.

S405: The terminal device may perform relaxed measurement on the same-frequency neighbor cell on the same-frequency frequency point according to the adjusted _{intra-frequency relaxed measurement threshold threshold intrarelaxmeasure ;} Perform relaxed measurements on inter-frequency adjacent cells.

It should be noted that the above S403-S405 are optional steps, and the communication system can realize the adjustment of the intra-frequency relaxation measurement threshold threshold _{intrarelaxmeasure} and the inter-frequency relaxation measurement threshold threshold _{nonintrarelaxmeasure} through the base station and/or the terminal device .

It should also be noted that the embodiment of the present application is described by taking the base station directly configuring the relaxed measurement threshold for the terminal device as an example. Optionally, the base station may send other information to the terminal device to indirectly configure a relaxed measurement threshold for the terminal device.

For example, the base station may send multiple intra-frequency measurement threshold candidate values and multiple inter-frequency relaxed measurement threshold candidate values to the terminal device, so that the terminal device can In the selected value, select the same-frequency relaxation measurement threshold, and select the inter-frequency relaxation measurement threshold among multiple alternative frequency relaxation measurement thresholds. Wherein, each threshold candidate value conforms to a corresponding threshold value selection rule. In addition, the above threshold candidate value may be specified by the protocol and stored in the base station, or calculated by the base station according to a set calculation method.

For another example, the base station may send the intra-frequency relaxation measurement threshold calculation parameter and the inter-frequency relaxation measurement threshold calculation parameter to the terminal device, so that the terminal device may calculate the intra-frequency relaxation measurement threshold calculation parameter according to the intra-frequency relaxation measurement threshold calculation parameter. The measurement threshold is to calculate the inter-frequency relaxation measurement threshold according to the calculation parameter of the inter-frequency relaxation measurement threshold. Among them, the threshold calculation parameters may include the initial same-frequency/different-frequency relaxation measurement threshold and/or threshold adjustment value (for example, k1-k4 in formula 1-formula 4, or the basis for relaxing the measurement threshold at the initial same-frequency/different frequency increase or decrease the value above).

An embodiment of the present application provides a measurement method, in which a terminal device can determine whether to perform relaxed measurement on neighboring cells on a target frequency point by relaxing a measurement threshold. Therefore, the communication system can flexibly set the relaxed measurement threshold, so that the terminal device can flexibly perform relaxed measurement on the adjacent cells on the target frequency point, so as to ensure the communication performance of the terminal device and save the power consumption of the terminal device .

Based on the same technical concept, the embodiment of the present application also provides a communication device, which can be applied to a base station or a terminal device in the communication system shown in FIG. 1 , and can implement the measurement method provided in the above embodiments.

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

#1: Low Mobility Scenarios

#2: Non-Cell Edge Scenarios

#3: Low speed + non-cell edge scenarios

Applicability of the RRM relaxation method to Scenario #1 and Scenario #2:

scene 1:

Protocol - RRM measurement relaxation lengthening

Scene two:

Protocol - RRM measurement relaxation lengthening

Measurement interval scaling factor FFS

Option 1: Fixed value

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

Separate values for Scenario #1 and Scenario #2 are for further study

Option 2: Network configurable values

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

Table 1. Power Saving Gain for Extended Measurement Period

DRX=0.32 DRX=0.64 DRX=1.28s DRX=2.56 N=4 27.9% 24.75% 19.7% 14.2% N=8 32.5% 28.6 23.0% 16.5%

It can be seen that extending the measurement interval by N times can bring obvious energy saving gains. When the DRX is larger, the gain of 8x expansion is not obvious compared with 4x expansion. Since networks may have different preferences in different scenarios, a flexible approach is to configure scaling factors per network. For example, the network can be configured with different relaxation factors for different scenarios. Alternatively, the relaxation factor may also consider the degree of movement or location of the UE. The value range of the relaxation factor is {2,8}.

Proposal 1: For scenarios #1 and #2, the scaling factor can be measured loosely by network configuration.

In the last meeting, RAN2 sent an LS to RAN4[2]. The agreement is reproduced below:

RAN2 discussed issues related to NR energy saving RRM measurements and reached the following agreement:

1. The network side broadcasts the corresponding relaxation trigger criterion parameters, and enables the RRM measurement relaxation feature.

2. When the network configures both low mobility and non-edge criterion parameters. The UE can perform measurement relaxation according to one of the following options indicated by the network:

- Option a: The UE uses the low mobility criterion and the non-cell-edge criterion, ie: the UE can perform relaxation only if both conditions are met at the same time. The specific relaxation behavior depends on the discussion and decision-making of RAN4;

- Option b: UE uses low mobility criterion or non-cell-edge criterion (the choice can be left to UE implementation), ie UE can relax when low-mobility or non-cell-edge criterion is satisfied. And the detailed relaxation behavior is the same as if the network only configures the standard.

3. In the non-cell edge standard, when the network side configures the RSRP and RSRQ thresholds, only when the RSRP and RSRQ thresholds are both satisfied, the UE can relax.

4. FFS of RAN4—parameters we need (such as the measurement relaxation time interval since the last measurement of cell reselection, and the value range of this time interval).

RAN2 has agreed with the network to indicate option a or option b. For option a, it has been agreed at the RAN4#93 meeting that the UE is not required to meet the same-frequency and inter-frequency adjacent cell measurement requirements of Scenario #3. Therefore, the behavior of the UE is unambiguous.

For option b, when the network configures the parameters of both low mobility and non-cell-edge criteria, the UE can perform relaxation when the low-mobility or non-cell-edge criteria are met. If both criteria are met, we consider that UE will not stop measurements in this case. Since the network indicates option b to the UE, it means that the network expects to relax the measurements and expects the measurement results reported by the UE. Otherwise, the network will indicate option a to the UE. Therefore, if both criteria are met, the UE may choose either one, depending on UE implementation.

Suggestion 2: When the network configures the standard parameters of low mobility and non-edge cells at the same time,

- If the network indicates option a, the UE stops intra-frequency and inter-frequency neighbor cell measurements when these two criteria are met.

- If the network indicates option b, the UE performs corresponding relaxed measurements depending on which conditions are met. If these two conditions are met, it is up to the UE to select one (low mobility or non-edge cell) and perform the corresponding relaxed measurements.

In NB-IoT, the following loose latency monitoring measurement rules are defined in TS 36.304. The time interval from the last cell reselection measurement is defined as 24 hours.

5.2.4.12.0 Relaxed monitoring metrics rules

When the UE is required to perform intra-frequency or inter-frequency measurement according to the measurement rules in Section 5.2.4.2 or 5.2.4.2a, the UE may choose not to perform intra-frequency or inter-frequency measurement in the following cases:

- Satisfy the relaxed monitoring criteria in subsection 5.2.4.12.1 during TSearchDeltaP, and

- less than 24 hours have passed since the last cell reselection measurement was performed, and

- After the UE selects or reselects to a new cell, it performs at least TSearchDeltaP times of intra-frequency or inter-frequency measurements.

In power saving mode, if both conditions are met, and the network indicates option a, the UE will stop intra-frequency and inter-frequency neighbor cell measurements. In this case, the interval since the last cell reselection measurement should be considered. Obviously, 24 hours is not suitable for power-saving terminals. This value should take into account network deployment, propagation environment, UE moving direction, UE speed, UE location, etc. If the cycle configuration is too long, the mobile performance of the UE will be affected, and if the cycle configuration is too short, the power saving gain will be reduced. In general, we consider the time interval for measurement relaxation (stop measurement), because the last measurement of cell reselection is at the level of minutes.

Suggestion 3: From the last cell reselection measurement, the time interval for measurement relaxation (stop measurement) is at the minute level.

l RRM measurement relaxes inter-frequency layer with high priority RAN4 discusses RRM measurement with higher priority in inter-frequency layer.

"RRM measurement relaxes high priority inter-frequency layer

Option 1: When S _rxlev >S _{nonIntraSearchP} and S _qual >S _{nonIntraSearchQ} , for higher priority inter-frequency measurements, it is not expected to relax the current measurement latency requirements. When S _rxlev ≤ S _{nonIntraSearchP} or S _qual ≤ S _{nonIntraSearchQ} , the relaxed measurement requirements for the high priority frequency layer are the same as those for the peer/low priority frequency layer.

Option 2: In high-speed mobile scenarios, the measurement of high-priority carriers should not be relaxed (scenario #2).

Option 3: The weighting of higher priority carriers should not be relaxed.

Meanwhile, RAN2 is discussing the same issue.

Agreements that RAN2 has previously reached:

1. Whether the high-priority frequency point is loose or not depends on the network configuration. How to configure it is for further study. RAN2 is discussing the high priority measurement relaxation indication and wants to ask RAN4 about the high priority carrier relaxation behavior:

1. For the case of S _rxlev >S _{nonIntraSearchP} and S _qual >S _{nonIntraSearchQ} , if the relaxation criterion defined by RAN2 is met, does RAN4 envisage further relaxing the measurement of higher priority carriers than Thigher_priority_search?

2. For the case of S _rxlev <S _{nonIntraSearchP} or S _qual <S _{nonIntraSearchQ} , if the relaxation criteria defined by RAN2 are met, is there any performance or system advantage that only relaxes the measurement of equal/low priority carriers, but not the measurement of high priority carriers? Measurement?

In the current specification, if S _rxlev >S _{nonIntraSearchP} and S _qual >S _{nonIntraSearchQ} , the UE shall at least search the inter-system E-UTRAN layer with higher priority in each Thigher_priority_search, where Thigher_priority_search=(60*Nlayers) It takes effect in seconds. For this case, the requirements are already loose, so the benefit of further relaxation is negligible.

For the case of S _rxlev < S _{nonIntraSearchP} or S _qual < S _{nonIntraSearchQ} , the UE behavior is to measure the inter-frequency layers with higher, same or lower priority layers. In the current specification, the measurement requirements for high priority, equal priority or low priority are the same in this case. In the energy-saving scenario, if the measurement of the high-priority layer is relaxed, energy-saving benefits can be predicted (as shown in Table 1). Also, since the measurements are relaxed to a higher priority, the validity of the measurement results is not a big issue. Since the energy saving trigger criteria are specified for low mobility and non-cell edge scenarios, in both cases there is no strong command to obtain measurement results quickly. However, this contradicts the motivation for introducing different priority tiers (high, equal and low) if they have the same measurement requirements. Therefore, S _rxlev ≤ S _{nonIntraSearchP} or S _qual ≤ S _{nonIntraSearchQ} , the relaxation requirements of high priority frequency layers may be different from those of equal/low priority frequency layers.

Suggestion 4: When S _rxlev >S _{nonIntraSearchP} and S _qual >S _{nonIntraSearchQ} , do not relax the current measurement delay requirement for high-priority inter-frequency measurement. When S _rxlev ≤ S _{nonIntraSearchP} or S _qual ≤ S _{nonIntraSearchQ} , the relaxed measurement requirement for the high-priority frequency layer is different from the relaxed measurement requirement for the equal/low-priority frequency layer.

Reduce the number of frequency layers

From UE's point of view, the paging opportunity is essential and cannot be missed. Theoretically, UE can perform intra-frequency measurement at the time of paging, which means that intra-frequency measurement will not introduce additional large power consumption.

For inter-frequency measurement, UE needs to wake up additionally during DRX-OFF to avoid paging reception drop. We know that the measurement requirements for split frequencies scale with the number of frequencies. That is, when the number of inter-frequency layers is greater than 1, the normalized power is not increased.

Suggestion 5: Reducing the number of inter-frequency layers measured in the idle state cannot bring about energy-saving gains.

Impact on earlier measurement reports

The CA/DC enhancement introduces the function of reporting measurement reports in advance. The purpose of EMR is to speed up the establishment of CA/DC when the UE enters the connected state. If the UE is in power saving mode, normal measurement may be affected. There are two situations that need to be discussed separately.

In scenarios #1 and #2, relaxation measurements should be performed. As far as we understand, EMR is not an urgent function, and measurements obtained from relaxation measurements on the carrier indicated by the EMR configuration can still be applied to EMR.

Proposal 6: In scenarios #1 and #2, measurements obtained from relaxed measurements can still be applied to EMR.

In scenario #3, when the UE is in power saving mode, the UE may stop neighbor cell measurements. However, if the UE is also configured with EMR configuration in the RRC release, when the UE is about to enter the RRC connected mode, the UE has no information about the neighbor cell measurement results. In this case, the UE may need to establish CA or DC due to traffic load. EMR measurements are reasonable. Considering power saving, the UE can perform relaxed measurements.

Proposal 7: In Scenario #3, when the UE is configured with EMR, the UE shall perform relaxed measurements.

The impact of cross-slot scheduling energy-saving technology on RRM

The last meeting of RAN1 was discussing cross-slot scheduling energy saving. The impact framework of BWP switching is basically as follows.

Summary: "If DCI format 1_1 (or 0_1) indicates a target DL (or UL) BWP different from the active DL (or UL) BWP, the minimum applicable scheduling offset indication field (if present in the DCI format ) indicates the minimum scheduling offset limit applied to the target BWP. Note: No change in specification is required.

Therefore, in RAN4, there is no need to discuss prolonging the BWP handover delay. In other words, the DCI-based BWP handover delay requirement in RAN4 remains unchanged.

Recommendation 8: The DCI-based BWP handover delay requirement in RAN4 is not affected by cross-slot scheduling.

This paper discusses the problem of measurement relaxation in energy saving. The proposal is as follows:

Proposal 1: For scenarios #1 and #2, the scaling factor can be measured loosely by network configuration.

Suggestion 2: When the network configures the low mobility and non-edge cell standard parameters at the same time, - if the network indicates option a, when these two standards are met, the UE stops the intra-frequency and inter-frequency neighbor cell measurement. - If the network indicates option b, the UE performs corresponding relaxed measurements depending on which conditions are met. If these two conditions are met, it is up to the UE to select one (low mobility or non-edge cell) and perform the corresponding relaxed measurements.

Suggestion 3: From the last cell reselection measurement, the time interval for measurement relaxation (stop measurement) is at the minute level.

Suggestion 4: When S _rxlev >S _{nonIntraSearchP} and S _qual >S _{nonIntraSearchQ} , do not relax the current measurement delay requirement for high-priority inter-frequency measurement. When S _rxlev ≤ S _{nonIntraSearchP} or S _qual ≤ S _{nonIntraSearchQ} , the relaxed measurement requirement for the high-priority frequency layer is different from the relaxed measurement requirement for the equal/low-priority frequency layer.

Suggestion 5: Reducing the number of inter-frequency layers measured in the idle state cannot bring about energy-saving gains.

Recommendation 6: In Scenarios #1 and #2, measurements obtained from relaxed measurements can still be applied to EMR.

Proposal 7: In Scenario #3, when the UE is configured with EMR, the UE shall perform relaxed measurements.

Recommendation 8: DCI-based BWP handover delay requirement in RAN4 is not affected by cross-slot scheduling.
