Description

Measuring method and device
The present application claims priority of chinese patent application entitled "a method for paging UE under eDRX, UE and network device" filed by chinese patent office on 31/03/2020/63 with application number 202010242285.5, which is 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 Radio Resource Management (RRM) measurement, so as to implement cell reselection (reselection), thereby changing a cell where the terminal device resides to obtain continuous service. The RRM measurement is a cell measurement, which specifically includes a common-frequency measurement and a pilot-frequency/inter-system measurement.
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 where the cell is located, the threshold for starting RRM measurement, and the like. When the terminal equipment receives the system message of the serving cell and the target frequency points (including the same-frequency points and/or different-frequency points) notified by the base station managing the serving cell, RRM measurement is performed on the adjacent cells on the target frequency points according to the measurement configuration information, and cell reselection is performed according to the measurement results.
In the process of performing RRM measurement by the terminal device, the terminal device may classify the target frequency points into the following three categories according to a 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 cell RRM measurement triggering conditions set by the communication system for different types of target frequency points are different, and the corresponding cell reselection rules set for different types of target frequency points are also different, 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 RRM measurement and cell reselection performed by the terminal device in the RRC idle state and the 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 relaxing the RRM measurement is introduced in the communication field, but a scheme for achieving the RRM measurement is not discussed yet.

5) The measurement configuration information of the cell is broadcasted by a base station managing the cell through a system message (e.g., system information blocks (SIB 2)), and the terminal device accessing the cell performs RRM measurement.
Wherein the measurement configuration information includes a priority (cell reselection priority) of a frequency point where the cell is located, and a measurement threshold (S) search ). The measurement threshold may include a common frequency measurement threshold (Sintrasearch, which may be S in the following description) intrasearch Denoted), and a pilot/pilot system measurement threshold (Snonintrasearch, which may be S in the following description) nonintrasearch Representation). It should be noted that, when the signal quality is represented by a signal quality parameter in the communication system, the above common-frequency measurement threshold and the different-frequency/different-system measurement threshold are also corresponding to 1; when represented by a plurality of signal quality parameters in the communication system, the above thresholds are also correspondingly a plurality.
Illustratively, when the communication system represents the signal quality by the signal amplitude and the signal strength, the intra-frequency measurement threshold includes: common frequency measurement signal amplitude threshold (SintrasearchP, which can be used in the following description) is intrasearch P) and a common-frequency measurement signal strength threshold (SintrasearchQ, which may be S in the following description) intrasearch Q represents). Wherein S is intrasearch P is used to indicate the signal amplitude threshold of the same frequency measurement, S intrasearch Q is used to indicate the signal strength threshold for the intra-frequency measurements. In the current measurement strategy, the cell is servedWhen the terminal equipment of a cell measures that the signal quality of the cell meets the following conditions, the terminal equipment starts to measure the adjacent cell on a service frequency point (the frequency point where the service cell is located): signal amplitude (S) in signal quality of the cell rxlev ) Greater than S intrasearch P, and signal strength (S) in signal quality of the cell qual ) Greater than S intrasearch Q。
Meanwhile, the pilot frequency/pilot system measurement threshold includes: pilot frequency measurement signal amplitude threshold (SnonintrasearchP, which may be used in the following description of the invention) nonintrasearch P) and pilot measurement signal strength threshold (SnonintrasearchQ, which may be S in the following description) nonintrasearch Q represents). Wherein S is nonintrasearch P is used to indicate the signal amplitude threshold (in dB) for NR inter-frequency and inter-RAT measurements, S nonintrasearch Q is used to indicate the signal strength threshold (in dB) for the inter-frequency and inter-RAT measurements of inter/inter-system measurements. In the current measurement strategy, when the terminal device using the cell as a serving cell measures that the signal quality of the cell meets the following conditions, the terminal device performs measurement on a neighboring cell on a high-priority target frequency point: signal amplitude (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; and when the cell signal quality measured by the terminal equipment does not meet the condition, the terminal equipment performs measurement on adjacent cells on the high-priority target frequency point, the equal-priority target frequency point and the low-priority target frequency point.
6) And the target frequency point measured by the cell is configured for the terminal equipment by the base station. And the terminal equipment measures the adjacent cell on the target frequency point so as to reselect or switch the cell according to the obtained measurement result.
According to the relationship between the target frequency point and the service frequency point (i.e. 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 point: i.e. the service frequency point.
Pilot frequency point: a target frequency point different from the serving frequency point. Further, according to the relative relationship between the priority of the pilot frequency point and the priority of the service frequency point, the pilot frequency points can be divided into three categories: high priority target frequency point, equal priority target frequency point, low priority target frequency point. The high-priority target frequency point is a pilot frequency point with priority higher than that of the service frequency point; the target frequency points with the same priority are pilot frequency points with the same priority as the service frequency points; the low-priority target frequency point is an pilot frequency point with the priority lower than that of the service frequency point.
In addition, for convenience of distinguishing and describing, in the embodiment of the present application, the neighboring cell on the co-frequency point is referred to as a co-frequency neighboring cell, and the neighboring cell on the inter-frequency point is referred to as an inter-frequency neighboring cell.
7) Cell measurements, including RRM measurements and Radio Link Monitoring (RLM) measurements.
8) "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 to which the measurement method provided in the embodiment of the present application is applicable. 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 the 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 (5 g) communication system (also called a New Radio (NR) communication system), a future sixth generation communication system and other communication systems that evolve, a Long Term Evolution (LTE) communication system, a vehicle to anything (V2X), a Long Term Evolution-vehicle networking (LTE-vehicle, LTE-V), a vehicle to vehicle (V2V), a vehicle networking, machine Type Communications (MTC), an internet of things (IoT), a Long Term Evolution-Machine to Machine (LTE-Machine to Machine, LTE-M), a Machine to Machine (M2M), and so on.
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, and as shown in the figure, the terminal device moves from cell a to cell b, so the terminal device needs to change the cell where it resides continuously through cell 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, a base station managing each cell broadcasts measurement configuration information of the cell in a cell coverage area managed by the base station through system information, and sends target frequency point configuration information of the cell through the system information or RRC information. The target frequency point configuration information includes target frequency points to be measured and may also include neighboring cells to be measured on each target frequency point. Therefore, after the terminal equipment receives the measurement configuration information of the service cell and the target frequency point configuration information, the terminal equipment performs measurement on the adjacent cell on the target frequency point according to the measurement configuration information, and performs cell reselection or cell switching according to the measurement result.
In order to make cell reselection or cell handover 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 such as the service quality 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 may be better, or a higher transmission rate (for example, a hot spot cell) may 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, when the terminal equipment carries out cell measurement, according to the relative relation between the priority of each target frequency point and the priority of the service frequency point, the pilot frequency points in the target frequency points can be divided into three types: 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 pilot frequency/pilot system measurement threshold, only the adjacent cell on a high-priority target frequency point is measured; and when the terminal equipment determines that the signal quality is not greater than the pilot frequency/pilot system measurement threshold, measuring adjacent regions on a high-priority target frequency point, an equal-priority target frequency point and a low-priority target frequency point.
Since the terminal device performs the cell measurement and is also the power consumption source of the terminal device, in order to ensure the communication performance of the terminal device and effectively save the power consumption of the terminal device, the concept of relaxing the measurement is introduced in the communication field. In performing the 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 frequency of measurement (e.g., increase the detection delay T) detect Increasing the measurement delay T measure Or increasing the evaluation delay T evaluate ) Or no cell measurement is performed.
The first embodiment is as follows:
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 adapted in the communication system shown in fig. 1. The embodiment of the present application specifically describes a case where the communication system represents the signal quality by the signal amplitude and the signal strength.
The terminal device stores a relaxation measurement threshold relaxmeasure . The relaxation measurement threshold is relaxmeasure For determining whether to perform relaxation measurements. The relaxation measurement threshold is relaxmeasure Comprises the following steps:
same-frequency relaxation measurement threshold intrarelaxmeasure : same-frequency relaxation measurement signal amplitude threshold intrarelaxmeasure P, and same frequency relaxation measurement signal strength threshold intrarelaxmeasure Q；
Pilot frequency relaxation measurement threshold nonintrarelaxmeasure : pilot frequency relaxation measurement signal amplitude threshold nonintrarelaxmeasure P, and pilot frequency relaxation measurement signal strength threshold nonintrarelaxmeasure Q。
Wherein the same-frequency relaxation measurement threshold is intrarelaxmeasure And the method is used for judging whether to carry out relaxation measurement on the adjacent regions with the same frequency. The pilot frequency relaxation measurement threshold nonintrarelaxmeasure And the method is used for judging whether to carry out relaxation measurement on the pilot frequency adjacent cell. Same-frequency relaxation measurement signal amplitude threshold intrarelaxmeasure P is a signal amplitude critical value of a serving cell for judging whether relaxation measurement is carried out on the adjacent cells with the same frequency; same frequency relaxation measurement signal strength threshold intrarelaxmeasure Q is the signal intensity critical value of the serving cell for judging whether to carry out relaxation measurement on the adjacent cells with the same frequency; pilot frequency relaxation measurement signal amplitude gateThreshold limit nonintrarelaxmeasure P is a signal amplitude critical value of the service cell for judging whether to carry out relaxation measurement on the pilot frequency adjacent cell; pilot frequency relaxation measurement signal strength threshold nonintrarelaxmeasure Q is the signal intensity critical value of the service cell for judging whether to carry out relaxation measurement on the pilot frequency adjacent cell.
In addition, the same-frequency relaxation measurement threshold is intrarelaxmeasure Is greater than a preset threshold standard initial value (which can be subsequently expressed by threshold Criterion S) and is less than a same-frequency measurement threshold S in the measurement configuration information of the serving cell intrasearch . Specifically, the threshold standard threshold Criterion S<Same-frequency relaxation measurement signal amplitude threshold intrarelaxmeasure P<Same frequency measuring signal amplitude threshold S intrasearch P; threshold standard starting value threshold Criterion S<Same frequency relaxation measurement signal strength threshold intrarelaxmeasure Q<Same frequency measuring signal strength threshold S intrasearch Q。
The pilot frequency relaxation measurement threshold nonintrarelaxmeasure Greater than a preset threshold standard starting value (which may be subsequently expressed by threshold Criterion S), and less than the inter-frequency/inter-system measurement threshold S in the measurement configuration information of the serving cell nonintrasearch . Specifically, the threshold standard starting value threshold Criterion S<Pilot frequency relaxation measurement signal amplitude threshold nonintrarelaxmeasure P<Pilot frequency measurement signal amplitude threshold S nonintrasearch P; threshold standard starting value threshold Criterion S<Pilot frequency relaxation measurement signal strength threshold nonintrarelaxmeasure Q<Pilot frequency measurement signal strength threshold S nonintrasearch Q。
Wherein, the threshold standard starting value threshold Criterion S is: and measuring an admission threshold. I.e. the terminal device can only measure signals with a signal quality above the threshold standard starting value threshold Criterion S. When the signal quality of a signal is below the threshold standard starting value threshold Criterion S, the terminal device cannot measure the signal.
The same frequency relaxation measuring doorThreshold limit intrarelaxmeasure The above conditions are satisfied, and the signal quality of the serving cell can relax the measurement threshold at the same frequency intrarelaxmeasure Measuring threshold S with same frequency intrasearch When the adjacent cells are within the range, performing relaxation measurement on the adjacent cells with the same frequency; otherwise, if the same-frequency relaxation measurement threshold is set intrarelaxmeasure Being lower than the threshold standard starting value threshold Criterion S, the terminal device starts to perform relaxed measurement on the same-frequency neighboring cell as long as measuring the signal of the serving cell, and the terminal device cannot be switched to the same-frequency neighboring cell in time under the condition that the signal quality of the serving cell is poor.
The pilot frequency relaxation measurement threshold nonintrarelaxmeasure The signal quality of the serving cell can be measured at the pilot frequency relaxation threshold by satisfying the above conditions nonintrarelaxmeasure With different frequency/different system measuring threshold S nonintrasearch When the pilot frequency is within the range, performing relaxation measurement on the pilot frequency adjacent cell; otherwise, if the pilot frequency relaxation measurement threshold is set nonintrarelaxmeasure If the signal quality is lower than the threshold standard starting value threshold Criterion S, the terminal device starts to perform relaxed measurement on the pilot frequency neighboring cell as long as the terminal device measures the signal of the serving cell, so that the terminal device cannot be switched to the pilot frequency neighboring cell in time under the condition that the signal quality of the serving cell is poor; if the pilot frequency relaxation measurement threshold is set nonintrarelaxmeasure Higher than the different frequency/different system measurement threshold S nonintrasearch When the signal quality of the service cell exceeds the different frequency/different system measurement threshold S nonintrasearch In the scenario of (2), the terminal device has a logic conflict of performing relaxed measurement on the pilot frequency adjacent cell or not performing measurement on the adjacent cell on the non-high-priority target frequency point.
In the embodiment of the present application, a relaxation measurement triggering mechanism of a terminal device for a neighboring cell with the same frequency is as follows:
the first method is as follows: when the terminal equipment determines the signal amplitude S in the signal quality of the serving cell rxlev >Same-frequency relaxation measurement signal amplitude threshold intrarelaxmeasure P, and serving cellSignal strength S of qual >Same-frequency relaxation measurement signal strength threshold intrarelaxmeasure And Q, the terminal equipment performs relaxation measurement on the adjacent regions with the same frequency, as shown in fig. 2A.
Correspondingly, when the terminal equipment determines the signal amplitude S in the signal quality of the serving cell rxlev Equal to or less than same frequency relaxation measurement signal amplitude threshold intrarelaxmeasure P, and/or the signal strength S of the serving cell qual Equal to or less than same frequency relaxation measurement signal strength threshold intrarelaxmeasure And Q, the terminal equipment carries out normal measurement on the adjacent regions with the same frequency.
The second method comprises the following steps: when the terminal equipment determines the signal amplitude S in the signal quality of the serving cell rxlev >Same-frequency relaxation measurement signal amplitude threshold intrarelaxmeasure P, or signal strength S of serving cell qual >Same frequency relaxation measurement signal strength threshold intrarelaxmeasure And Q, the terminal equipment carries out relaxation measurement on the adjacent regions with the same frequency.
Correspondingly, when the terminal equipment determines the signal amplitude S in the signal quality of the serving cell rxlev Equal to or less than same frequency relaxation measurement signal amplitude threshold intrarelaxmeasure P, and signal strength S of serving cell qual Equal to or less than same frequency relaxation measuring signal strength threshold intrarelaxmeasure And Q, the terminal equipment carries out normal measurement on the adjacent regions with the same frequency.
In one design, the terminal device may perform relaxation measurement on the co-frequency neighboring cells by reducing the measurement frequency of the co-frequency neighboring cells and/or reducing the number of the co-frequency neighboring cells (until cell measurement is not performed).
For example, the terminal device may use a measurement period T of a more normal common frequency intra Larger relaxed co-frequency measurement period T intrarelax And carrying out relaxation measurement on the adjacent regions with the same frequency. Optionally, T intrarelax ＝T intra *A1，A1>1. Wherein, the normal common-frequency measurement period T intra The normal measurement is, for example, a measurement period used when the terminal device performs normal measurement on the neighboring cells with the same frequency: do not make a relaxation surveyAmount of the compound (A).
For another example, the terminal device reduces the number of the neighboring cells with the same frequency from B0 to B1, where B0 and B1 are both integers greater than 0, and B1< B0. Optionally, B1= B0/A2, A2>1.
In the embodiment of the present application, the release measurement triggering mechanism of the terminal device for the inter-frequency neighboring cell is as follows:
the first method is as follows: when the terminal equipment determines the signal amplitude S in the signal quality of the serving cell rxlev >Pilot frequency relaxation measurement signal amplitude threshold nonintrarelaxmeasure P, and signal strength S of serving cell qual >threshold nonintrarelaxmeasure And Q, the terminal equipment performs relaxation measurement on the pilot frequency adjacent cell on the target frequency point, as shown in FIG. 2B.
When the terminal equipment determines the signal amplitude S in the signal quality of the serving cell rxlev Threshold of amplitude of pilot frequency relaxation measurement signal not more than nonintrarelaxmeasure P, and/or the signal strength S of the serving cell qual Equal to or less than pilot frequency relaxation measurement signal strength threshold nonintrarelaxmeasure And Q, the terminal equipment normally measures all target frequency points (including high-priority target frequency points, equal-priority target frequency points and low-priority target frequency points).
The second method comprises the following steps: when the terminal equipment determines the signal amplitude S in the signal quality of the serving cell rxlev >Pilot frequency relaxation measurement signal amplitude threshold nonintrarelaxmeasure P, or signal strength S of serving cell qual >threshold nonintrarelaxmeasure And Q, the terminal equipment performs relaxation measurement on the pilot frequency adjacent cell on the target frequency point.
When the terminal equipment determines the signal amplitude S in the signal quality of the serving cell rxlev Threshold of amplitude of pilot frequency relaxation measurement signal not more than nonintrarelaxmeasure P, and signal strength S of serving cell qual Pilot frequency relaxation measurement signal strength threshold not more than nonintrarelaxmeasure Q, the terminal equipment carries out the treatment on all target frequency points (including high-priority target frequency points, equal-priority target frequency points and low-priority targets)Frequency points) are measured normally.
In one design, the terminal device may perform relaxation measurement on the pilot frequency neighboring cell by reducing the measurement frequency of the pilot frequency neighboring cell and/or reducing the number of pilot frequency points.
For example, the terminal device may use a more normal inter-frequency measurement period T nonintra Larger relaxed inter-frequency measurement period T nonintrarelax And performing relaxation measurement on the pilot frequency adjacent region. Optionally, T nonintrarelax ＝T nonintra *A3，A3>1. Wherein, the normal pilot frequency measurement period T nonintra And the measurement period is used when the terminal equipment carries out normal measurement on the pilot frequency adjacent cell.
For another example, the terminal device reduces the number of the pilot frequency points from N0 to N1, where N0 and N1 are both integers greater than 0, and N1< N0. Optionally, N1= N0/A4, A4>1.
It should be further noted that, in the foregoing first and second manners, the terminal device may further determine the inter-frequency/inter-system measurement threshold S according to the signal quality of the serving cell and the inter-frequency/inter-system measurement threshold S nonintrasearch And determining whether to perform relaxation measurement on pilot frequency adjacent cells on all kinds of pilot frequency points or to perform relaxation measurement only on adjacent cells on a high-priority target frequency point. The specific judgment mechanism is as follows:
when the pilot frequency relaxes the amplitude threshold of the measurement signal nonintrarelaxmeasure P<Signal amplitude S in signal quality of serving cell rxlev Less than or equal to the threshold S of the amplitude value of the measurement signal of the pilot frequency/pilot system nonintrasearch P, and/or pilot frequency relaxation measurement signal strength threshold nonintrarelaxmeasure Q<Signal strength S in signal quality of serving cell qual Less than or equal to the threshold S of the strength of the measurement signal of the pilot frequency/pilot system nonintrasearch And Q, namely under the condition that the terminal equipment needs to measure all types of pilot frequency points, the terminal equipment performs relaxation measurement on pilot frequency adjacent regions on all types of pilot frequency points (including high-priority target frequency points, equal-priority target frequency points and low-priority target frequency points).
When the signal quality of the serving cell is inSignal amplitude S rxlev >The pilot frequency/pilot system measurement signal amplitude threshold S nonintrasearch P, and signal strength S in signal quality of serving cell qual >The pilot frequency/pilot system measures the signal intensity threshold S nonintrasearch And Q, namely under the condition that the terminal equipment only needs to measure the high-priority target frequency point and does not measure the target frequency points with the same priority and the low-priority target frequency points, the terminal equipment only executes relaxation measurement on pilot frequency adjacent regions on the high-priority target frequency points.
It should be noted that, in the embodiment of the present application, the relaxation measurement threshold is set relaxmeasure The base station configures the terminal equipment, for example, the communication system can design a new structure of RRC signaling, and the base station can set threshold relaxmeasure Carried in the RRC signaling. For another example, the base station may add a new field in the system message SIB2 and set the relaxed measurement threshold relaxmeasure Carried in this field. The relaxation measurement threshold relaxmeasure Or may be protocol specific and stored in the terminal device. The relaxation measurement threshold is relaxmeasure The calculation method may be calculated by the base station or the terminal device according to a protocol definition and stored in the terminal device, or calculated by the calculation method configured by the base station to the terminal device. The relaxation measurement threshold is relaxmeasure The terminal device may further select from a plurality of threshold candidate values, where the threshold candidate values may be specified by a protocol and stored in the terminal device, or configured for the terminal device by a base station. For example, the terminal device may select the relaxed measurement threshold based on at least one or a combination of the following relaxmeasure : the service priority of the terminal equipment, the service frequency point priority and the mobility information of the terminal equipment.
The higher the service priority of the terminal equipment is, the higher the relaxation measurement threshold selected by the terminal equipment is relaxmeasure The larger the value. Thus, the key industry is performed at the terminal equipmentAnd during service, the relaxation measurement threshold is increased, so that the terminal equipment does not perform relaxation measurement as much as possible, and the communication performance of the terminal equipment is ensured.
The higher the priority of the service frequency point of the terminal device (good data transmission rate of the service cell, good network coverage and the like), the higher the service quality of the service cell can be provided for the terminal device, and the relaxation measurement threshold selected by the terminal device is relaxmeasure The smaller the value. In this way, the terminal device enters a relaxed measurement mode as soon as possible, thereby reducing the power consumption of the terminal device.
The mobile information of the terminal device indicates that the terminal device is not located at the cell coverage edge, and/or when the mobile speed of the terminal device is low, it indicates that the serving cell can provide higher service quality for the terminal device, and the relaxation measurement threshold selected by the terminal device is threshold relaxmeasure The smaller the value. In this way, the terminal device enters a relaxed measurement mode as soon as possible, thereby reducing the power consumption of the terminal device.
Illustratively, the relaxation measurement threshold is threshold relaxmeasure The parameters in the formula I respectively accord with the following formulas I to IV:
threshold intrarelaxmeasure P＝k1*(S intrasearch p-threshold Criterion S) + threshold Criterion S formula one
threshold intrarelaxmeasure Q＝k2*(S intrasearch Q-threshold Criterion S) + threshold Criterion S formula two
threshold nonintrarelaxmeasure P＝k3*(S nonintrasearch P-threshold Criterion S) + threshold Criterion S formula three
threshold nonintrarelaxmeasure Q＝k4*(S nonintrasearch Q-threshold Criterion S) + threshold Criterion S formula IV
Wherein the above formulas are composed of 0-type yarn-woven fabric k1, 0-type yarn-woven fabric k2-type yarn-woven fabric 1, 0-type yarn-woven fabric k3-type yarn-woven fabric 1, and k1-k4 may be the same or different. In addition, the values of k1 to k4 in the above formula may be determined by the base station and configured to the terminal device, or specified by a protocol and stored in the terminal device, or determined by the terminal device.
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 equipment, the service frequency point priority and the mobility information of the terminal equipment. The mobility information of the terminal device may include, but is not limited to, location information, a moving speed, and the like of the terminal device. In this way, the terminal device or the base station may dynamically adjust the relaxed measurement threshold according to the current network state.
Illustratively, when the service priority of the terminal device is higher, the terminal device or the base station sets the value of k1-k4 to be larger, so that the value of the relaxation measurement threshold obtained according to k1-k4 is also larger. Therefore, when the terminal equipment carries out key service, the relaxation measurement threshold is improved, so that the terminal equipment does not carry out relaxation measurement as much as possible, and the communication performance of the terminal equipment is ensured.
Illustratively, when the priority of the service frequency point is higher, 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 higher the priority of the service frequency point is, the higher the service quality provided by the service cell for the terminal equipment is, and the lower the cell reselection or handover requirement of the terminal equipment is. Will relax the measurement threshold relaxmeasure The value setting is small, so that the terminal equipment enters a relaxation measurement mode as soon as possible, and the power consumption of the terminal equipment is reduced.
Illustratively, when the mobile information of the terminal device indicates that the terminal device is not located at the coverage edge of the cell and/or the mobile 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 equipment indicates that the terminal equipment is not positioned at the cell coverage edge and the mobile speed of the terminal equipment is low, which both indicate that the serving cell can provide high service quality for the terminal equipment. Will relax the measurement threshold threshold relaxmeasure The value setting is small, so that the terminal equipment enters a relaxation measurement mode as soon as possible, and the power consumption of the terminal equipment is reduced.
Exemplary, the relaxation measurement threshold is carried relaxmeasure The code of SIB2 of (a) is as follows:
Figure GDA0002806539590000151
Figure GDA0002806539590000161
wherein, the underlined codes in the codes are all relaxation measurement thresholds: "threshnonIntraRelaxMeasureP"represents the pilot frequency relaxation measurement signal amplitude threshold nonintrarelaxmeasure P；“threshnonIntraRelaxMeasureQ"represents the pilot frequency relaxation measurement signal strength threshold nonintrarelaxmeasure Q；“threshIntraRelaxMeasureP"represents the same frequency relaxation measurement signal amplitude threshold intrarelaxmeasure P；“threshIntraRelaxMeasureQ"represents the same frequency relaxation measurement signal strength threshold intrarelaxmeasure Q。
In the method, terminal equipment can determine whether to perform relaxation measurement on a neighboring cell on a target frequency point or not by relaxing a measurement threshold. Therefore, the communication system can flexibly set the relaxation measurement threshold to enable the terminal equipment to flexibly perform relaxation measurement on the adjacent region on the target frequency point, thereby not only ensuring the communication performance of the terminal equipment, but also saving the power consumption of the terminal equipment.
Example two:
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 adapted in the communication system shown in fig. 1. The embodiment of the present application specifically describes a case where a communication system represents signal quality by using signal amplitude and signal strength as an example.
The terminal device stores a relaxation measurement threshold relaxmeasure . Wherein, in the embodiment of the present application, the relaxation measurement threshold is relaxmeasure The parameters and the values of the parameters contained in the data base, and the terminal device obtains the threshold of relaxation measurement relaxmeasure The methods and the like can refer to the description in the first embodiment, and are not described herein again.
The terminal equipment also stores a plurality of same-frequency measurement signal quality ranges so as to perform relaxation measurement of different relaxation levels on the same-frequency adjacent cells according to the signal quality intensity of the serving cell, finally realize differential relaxation measurement and further improve the flexibility of relaxation measurement. 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 is, the larger the corresponding same-frequency relaxation level is, as shown in fig. 2C. And the larger the same-frequency relaxation level is, the lower the measurement frequency of the terminal device to the same-frequency adjacent cells or the smaller the number of the same-frequency adjacent cells is, in other words, the same-frequency relaxation level corresponds to the power consumption of the terminal device, and the larger the same-frequency relaxation level is, the lower the power consumption of the terminal device is.
Therefore, when the terminal device determines that the signal quality of the serving cell is greater than the relaxed measurement threshold relaxmeasure Same-frequency relaxation measurement threshold of (1) intrarelaxmeasure (the specific process may refer to the description in the embodiment), the terminal device may perform differentiation relaxation measurement on the neighboring cells with the same frequency according to the signal quality strength of the serving cell by the following steps:
when the terminal equipment determines that the signal quality of the serving cell is within a first common-frequency measurement signal quality range, the terminal equipment measures a period T according to a first relaxed common-frequency measurement period intrarelax_1 And B1_1 same-frequency adjacent regions on the same-frequency points are measured. Namely, the terminal equipment uses the same-frequency relaxation level 1 to perform relaxation measurement on the same-frequency adjacent regions.
When the terminal equipment determines that the signal quality of the serving cell is within a second common-frequency measurement signal quality range, the terminal equipment according to a second relaxation common-frequency measurement period T intrarelax_2 And measuring B1_2 same-frequency adjacent regions on the service frequency point. Namely, the terminal equipment uses the same-frequency relaxation level 2 to carry out relaxation measurement on the adjacent regions with the same frequency.
Wherein any value in the second co-frequency measurement signal quality range is greater than a value in the first co-frequency measurement signal quality range, T intrarelax_2 >T intrarelax_1 And/or B1_2<B1_1, B1_2 and B1_1 are all integers greater than 0. Exemplary, 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 quality ranges of the multiple co-frequency measurement signals are measured according to a co-frequency relaxation measurement threshold intrarelaxmeasure And at least one same-frequency relaxation level threshold. Wherein, the first common-frequency measurement signal quality range corresponding to the first common-frequency relaxation level is (common-frequency relaxation measurement threshold) intrarelaxmeasure First on-frequency relaxation level threshold](ii) a The second same-frequency measurement signal quality range corresponding to the second same-frequency relaxation level is (the first same-frequency relaxation level threshold, the second same-frequency relaxation level threshold)](ii) a … … the L-th co-frequency measurement signal quality range corresponding to the L-th co-frequency relaxation level is (L-1-th co-frequency relaxation level threshold, + ∞]。
In one design, each co-frequency relaxation level threshold is based on a co-frequency relaxation measurement threshold intrarelaxmeasure And (4) determining.
For example, first on-frequency relaxation level threshold = on-frequency relaxation measurement threshold intrarelaxmeasure * j, wherein j>1。
In particular, the first on-frequency relaxation level signal amplitude threshold intrarelaxlevel_1 P = same frequency relaxation measurement signal amplitude threshold intrarelaxmeasure P x j. Second same-frequency relaxation level signal amplitude threshold intrarelaxlevel_2 P = sameFrequency relaxation measurement signal amplitude threshold intrarelaxmeasure P*j 2 . L-1 common frequency relaxation level signal amplitude threshold intrarelaxlevel_L-1 P = same frequency relaxation measurement signal amplitude threshold intrarelaxmeasure P*j L-1 。

Second same frequency relaxation level signal strength threshold intrarelaxlevel_2 Q = same frequency relaxation measurement signal strength threshold intrarelaxmeasure Q*j 2 . L-1 common frequency relaxation level signal amplitude threshold intrarelaxlevel_L-1 Q = same frequency relaxation measurement signal strength threshold intrarelaxmeasure Q*j L-1 。
The value of j may be calculated by the base station through a set calculation method and configured to the terminal device, or calculated by the terminal device according to the 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: the service priority of the terminal equipment, the service frequency point priority and the mobility information of the terminal equipment. In this way, the terminal device or the base station may dynamically adjust the relaxed measurement threshold according to the current network state.
For example, when the service priority of the terminal device is lower, the priority of the service frequency point is higher, or the mobility information of the terminal device indicates that the terminal device is closer to the center of the service cell and/or the moving speed of the terminal device is lower, the set j value is smaller. Therefore, when the cell reselection or handover requirement of the terminal equipment is low, the terminal equipment can enter a relaxation measurement mode as soon as possible, and therefore the power consumption of the terminal equipment is reduced.
In another design, each co-frequency relaxation level threshold is configured for the terminal device by the base station, or is specified by a protocol and stored in the terminal device.
The terminal equipment also stores a plurality of pilot frequency measurement signal quality ranges so as to perform relaxation measurement of different relaxation levels on pilot frequency adjacent cells according to the signal quality intensity of the serving cell, finally realize differentiated relaxation measurement, and further improve the flexibility of relaxation measurement. Each pilot frequency measurement signal quality range corresponds to different pilot frequency relaxation levels, and the larger the value included in the pilot frequency measurement signal quality range is, the larger the corresponding pilot frequency relaxation level is, see fig. 2D. And the larger the pilot frequency relaxation level is, the lower the measurement frequency of the terminal equipment to the pilot frequency adjacent cells or the smaller the number of the pilot frequency adjacent cells is, in other words, the pilot frequency relaxation level corresponds to the power consumption of the terminal equipment, and the larger the pilot frequency relaxation level is, the lower the power consumption of the terminal equipment is.
Therefore, when the terminal device determines that the signal quality of the serving cell is greater than the relaxed measurement threshold relaxmeasure Inter-frequency relaxation measurement threshold of (1) nonintrarelaxmeasure (the specific process may refer to the description in the embodiment), the terminal device may perform differentiation relaxation measurement on the inter-frequency neighboring cell according to the signal quality strength of the serving cell by the following steps:

Namely, the terminal equipment uses the pilot frequency relaxation level 1 to perform relaxation measurement on the pilot frequency adjacent region.
When the terminal equipment determines that the signal quality of the serving cell is within a second pilot frequency measurement signal quality range, the terminal equipment according to a second relaxation pilot frequency measurement period T nonintrarelax_2 And measuring N1_2 pilot frequency adjacent regions on the service frequency point. Namely, the terminal equipment uses the pilot frequency relaxation level 2 to perform relaxation measurement on the pilot frequency adjacent region.
Wherein any value within the second inter-frequency measurement signal quality range is greater than a value within 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 all integers greater than 0. Exemplary, T nonintrarelax_2 ＝T nonintrarelax_1 *A7，N1_2＝N1_1/A8，A7>1，A8>1. The inter-frequency relaxation level 2 is higher than the inter-frequency relaxation level 1.
Wherein the plurality of pilot frequency measurement signal quality ranges are based on a pilot frequency relaxation measurement threshold nonintrarelaxmeasure And at least one inter-frequency relaxation level threshold. Wherein the first pilot frequency measurement signal quality range corresponding to the first pilot frequency relaxation level is (pilot frequency relaxation measurement threshold) nonintrarelaxmeasure First pilot frequency relaxation level threshold](ii) a The second pilot frequency measurement signal quality range corresponding to the second pilot frequency relaxation level is (the first pilot frequency relaxation level threshold, the second pilot frequency relaxation level threshold)](ii) a 5363 the L pilot frequency measurement signal quality range corresponding to the L pilot frequency relaxation level of … … is (L-1 pilot frequency relaxation level threshold +∞]。
In one design, each inter-frequency relaxation level threshold is based on an inter-frequency relaxation measurement threshold intrarelaxmeasure And (4) determining.
For example, first inter-frequency relaxation level threshold = inter-frequency relaxation measurement threshold nonintrarelaxmeasure * j, wherein j>1。
Specifically, the first pilot frequency relaxation level signal amplitude threshold nonintrarelaxlevel_1 P = pilot frequency relaxation measurement signal amplitude threshold nonintrarelaxmeasure P x j. Second pilot frequency relaxation level signal amplitude threshold nonintrarelaxlevel_2 P = pilot frequency relaxation measurement signal amplitude threshold nonintrarelaxmeasure P j 2 . L-1 pilot frequency relaxation level signal amplitude threshold nonintrarelaxlevel_L-1 P = pilot frequency relaxation measurement signal amplitude threshold nonintrarelaxmeasure P j L-1 。
First pilot frequency relaxation level signal strength threshold nonintrarelaxlevel_1 Q = pilot frequency relaxation measurement signal strength threshold nonintrarelaxmeasure Q j. Second pilot frequency relaxation level signal strength threshold nonintrarelaxlevel_2 Q = pilot frequency relaxation measurement signal strength threshold nonintrarelaxmeasure Q j 2 . L-1 pilot frequency relaxation level signal amplitude threshold nonintrarelaxlevel_L-1 Q = pilot frequency relaxation measurement signal strength threshold nonintrarelaxmeasure Q j L-1 。
The value of j may be calculated by the base station through a set calculation method and configured to the terminal device, or calculated by the terminal device according to the 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: the service priority of the terminal equipment, the service frequency point priority and the mobility information of the terminal equipment. The value rule of j may refer to the value rule when the threshold of the signal strength of the same frequency relaxation level is calculated, and is not described herein again.

There are three main scenarios to relax the measurement/cell identification/evaluation requirements.
#1: low mobility scenarios
#2: non-cell edge scenarios
#3: low speed + non-cell edge scenes
Applicability of the RRM relaxation method to scene #1 and scene #2:
scene #1:
protocol-RRM measurement relaxation lengthening
Scene two:
protocol-RRM measurement relaxation lengthening
Measurement interval scaling factor FFS
Option 1: fixed value
FFS values of scene #1 and scene #2 are the same
The individual values of scene #1 and scene #2 are to be further studied
Option 2: network accountability
Applicability of the RRM relaxation method to scene #1 and scene #2: the power consumption results in the SI phase are discussed as to how the measurements are relaxed. Details of the simulation assumptions are in the appendix of TS 38.840. The simulation results are shown in Table 1[3. Table 1 gives 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 a factor of N can bring significant energy savings gains. The gain of 8-fold extension over 4-fold extension is not significant when DRX is larger. Since networks may have different preferences in different scenarios, a flexible approach is to configure the expansion factor per network. For example, the network may configure different relaxation factors for different scenarios. Alternatively, the relaxation factor may also take into account the degree of movement or location of the UE, etc. The value range of the relaxation factor is 2,8.
Suggestion 1: for scenarios #1 and #2, the loose measurement expansion factor may be configured per network.
On the last conference, RAN2 sends an LS to RAN4[2 ]. The protocol is replicated as follows:
RAN2 discusses the problems associated with NR energy-saving RRM measurements and has agreed to:
1. and the network side broadcasts a corresponding relaxation triggering criterion parameter and starts the RRM measurement relaxation characteristic.
2. When the network configures both low mobility and non-edge criteria parameters. The UE may perform measurement relaxation according to one of the following options as indicated by the network:
option a UE uses low mobility and non-cell edge criteria, i.e.: only if both conditions are met, the UE can perform relaxation. The specific relaxation behavior depends on the discussion and decision of the RAN 4;
option b UE uses low mobility criteria or non-cell-edge criteria (the choice may be left to the UE implementation), i.e.: the UE may relax when low mobility or non-cell-edge criteria are met. While the detailed relaxation behavior is the same as if the network were only configured with the standard.
3. In the non-cell-edge criteria, when the network side configures RSRP and RSRQ thresholds, the UE may relax only when both RSRP and RSRQ thresholds are met.
FFS of ran4-the parameters we need (e.g. the measurement relaxation time interval since the last measurement in cell reselection, and the range of values for this time interval).
The RAN2 has agreed to the network indication option a or option b. For option a, it has been agreed at RAN4#93 conference, and it is not necessary for the UE to meet the intra-frequency and inter-frequency neighbor measurement requirements of scenario # 3. Thus, the behavior of the UE is explicit.
For option b, when the network configures the parameters of the low mobility and non-cell-edge criteria at the same time, the UE may perform a relaxation when the low mobility or non-cell-edge criteria are met. If both criteria are met, we consider that the UE will not stop the measurement in this case. Since the network indicates option b to the UE, this means that the network desires to relax the measurements and desires the measurement results reported by the UE. Otherwise, the network will indicate option a to the UE. Thus, the UE may select either one if both criteria are met, depending on the UE implementation.
And (2) suggestion: when the network is configured with both low mobility and non-edge cell criteria parameters,
if the network indicates option a, the UE stops the intra-frequency and inter-frequency neighbor measurements when both criteria are met.
-if the network indicates option b, the UE performs the corresponding loose measurement according to which conditions are fulfilled. If both conditions are met, selection of one (low mobility or non-edge cell) and corresponding loose measurements are performed by the UE.
In NB-IoT, the following relaxed 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 metric rule
When the UE is required to perform the intra-frequency or inter-frequency measurement according to the measurement rule in section 5.2.4.2 or 5.2.4.2a, the UE may choose not to perform the intra-frequency or inter-frequency measurement under the following conditions:
-satisfying the relaxed monitoring criterion in section 5.2.4.12.1 during TSearchDeltaP, and
-less than 24 hours have elapsed since the last cell reselection measurement was performed, and
after selecting or reselecting a new cell, the UE performs at least TSearchDeltaP times of intra-frequency or inter-frequency measurements.
In the power saving mode, if both conditions are met and the network indicates option a, the UE will stop the intra-frequency and inter-frequency neighbor measurements. In this case, the interval from the last cell reselection measurement should be considered. It is clear that 24 hours is not suitable for power saving terminals. This value should take into account network deployment, propagation environment, UE movement direction, UE velocity, UE location, etc. Too long a periodic configuration may affect the mobility performance of the UE, and too short a periodic configuration may reduce the power saving gain. In general, we consider the time interval for measurement relaxation (stop measurement) because the last measured cell reselection was of the order of minutes.
Suggestion 3: the time interval for measurement relaxation (stop of measurement) is in the order of minutes from the last cell reselection measurement.
RRM measurement the inter-frequency layer RAN4 with a higher priority has discussed RRM measurements with a higher priority of the inter-frequency layer.
' RRM measurement relaxes high priority pilot frequency layer
Option 1: when S is rxlev >S nonIntraSearchP And S qual >S nonIntraSearchQ In time, for pilot frequency measurement with higher priority, it is not desirable to relax the current measurement delay requirement. When S is 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 a high-speed moving scenario, the measurement of the high priority carrier should not be relaxed (scenario # 2).
Option 3: the weighting of higher priority carriers should not be relaxed.
At the same time, the RAN2 is also discussing the same problem.
Agreement RAN2 has previously agreed:
1. whether the high priority frequency points are loose depends on the network configuration. How to configure is under study. RAN2 is discussing a high priority measurement relaxation indication and wants to ask RAN4 about the high priority carrier relaxation behavior:
1. for S rxlev >S nonIntraSearchP And S qual >S nonIntraSearchQ If the relaxation criteria defined by RAN2 are met, is RAN4 to assume further relaxation of the measurements of higher priority carriers than thigh _ priority _ search?
2. For S rxlev <S nonIntraSearchP Or S qual <S nonIntraSearchQ If the relaxation criteria defined by RAN2 are met, is there performance or system advantage to relax measurements only for equal/low priority carriers, but not for high priority carriers?
In the present specification, if S rxlev >S nonIntraSearchP And S qual >S nonIntraSearchQ Then the UE should search at least every thigh _ priority _ search for the inter-system E-UTRAN layer with higher priority, where thigh _ priority _ search = (60 × nlayers) takes effect after second. For this case, the requirements are already relaxed, so the benefit of further relaxation is negligible.
For S rxlev <S nonIntraSearchP Or S qual <S nonIntraSearchQ The UE behavior is to measure the inter-frequency layer with higher, same or lower priority layers. In the current specification, the measurement requirements for high, medium or low priority are the same in this case. In the power saving scenario, if the measurement of the high priority layer is relaxed, the power saving benefit can be predicted (as shown in table 1). Furthermore, since the measurement is relaxed to a higher priority, the validity of the measurement result is not a big problem. Since the energy saving triggering criteria are specified for low mobility and non-cell edge scenarios, there is no strong command to get the measurement results quickly in both cases. However, if different priority layers (high, equal and low) have the same measurement requirements, this is contradictory to the motivation to introduce different priority layers. Thus, S rxlev ≤S nonIntraSearchP Or S qual ≤S nonIntraSearchQ The relaxation requirements of the high priority frequency layer may be different from the relaxation requirements of the equal priority/low priority frequency layer.
Suggestion 4: when S is rxlev >S nonIntraSearchP And S qual >S nonIntraSearchQ In time, the requirement of current measurement time delay is not relaxed for the pilot frequency measurement with high priority. When S is rxlev ≤S nonIntraSearchP Or S qual ≤S nonIntraSearchQ Meanwhile, the loose measurement requirement on the high-priority frequency layer is different from that of the equal/low-priority frequency layer.
Reducing the number of frequency layers
From the UE perspective, a paging occasion is essential and cannot be missed. Theoretically, the UE can perform the same-frequency measurement at the paging time, which means that the same-frequency measurement does not introduce additional large power consumption.
For inter-frequency measurements, the UE needs to wake up additionally during DRX-OFF to avoid a drop in paging reception. It is known that the measurement requirements for inter-frequencies scale with the number of frequencies. That is, when the number of pilot frequency layers is greater than 1, the normalized power is not raised.
Suggestion 5: the number of pilot frequency layers measured in an idle state is reduced, and energy-saving gain cannot be brought.
Impact on early measurement reporting
The CA/DC enhancement introduces the function of reporting the measurement report in advance. The purpose of the EMR is to speed up CA/DC establishment when the UE enters the connected state. Normal measurements may be affected if the UE is in power saving mode. There are two cases that need to be discussed separately.
In scenarios #1 and #2, relaxation measurements should be performed. To our knowledge, EMR is not an immediate function, and measurements made by relaxation measurements on the carrier wave indicated by the EMR configuration can still be applied to EMR.
Proposal 6 is as follows: in scenarios #1 and #2, the measurements from the relaxation measurements are still applicable to the EMR.
In scenario #3, the UE may stop neighbor measurements when the UE is in power saving mode. However, if the UE also configures EMR configuration in RRC release, the UE has no information about neighbor measurement results when the UE is ready to enter RRC connected mode. In this case, the UE may need to establish CA or DC due to traffic load. EMR measurements are reasonable. The UE may perform relaxation measurements in view of power saving.
Suggestion 7: in scenario #3, the UE will perform a relaxation measurement when the UE configures the EMR.
Impact of cross-slot scheduling energy saving technology on RRM
RAN1 was discussing cross-slot scheduling energy savings the last time the conference was. The framework of the impact of BWP switching is basically as follows.
To summarize: "if DCI format 1_1 (or 0_1) indicates a target DL (or UL) BWP different from an activated DL (or UL) BWP. The minimum applicable scheduling offset indication field (if present in the DCI format) indicates a minimum scheduling offset restriction to be applied to the target BWP. Note: the specification need not be changed.
Therefore, in the RAN4, there is no need to discuss extending the BWP handover delay. In other words, the DCI based BWP handover latency requirements in RAN4 are not changed.
Suggestion 8: DCI-based BWP handover latency requirements in RAN4 are not affected by cross-slot scheduling.
The measurement relaxation problem in energy saving is discussed herein. The following are proposed:
suggestion 1: for scenarios #1 and #2, the relaxed measurement spreading factor may be configured per network.
Proposal 2: when the network configures both low mobility and non-edge cell criteria parameters, if the network indicates option a, the UE stops intra-and inter-frequency neighbor measurements when both criteria are met. -if the network indicates option b, the UE performs the corresponding loose measurements according to which conditions are fulfilled. If both conditions are met, selection of one (low mobility or non-edge cell) and corresponding loose measurements are performed by the UE.
Suggestion 3: the time interval for measurement relaxation (stop of measurement) is in the order of minutes from the last cell reselection measurement.
Suggestion 4: when S is rxlev >S nonIntraSearchP And S qual >S nonIntraSearchQ In time, the current measurement time delay requirement is not relaxed for the pilot frequency measurement with high priority. When S is rxlev ≤S nonIntraSearchP Or S qual ≤S nonIntraSearchQ Meanwhile, the loose measurement requirement on the high-priority frequency layer is different from that of the equal/low-priority frequency layer.
Suggestion 5: the number of pilot frequency layers measured in an idle state is reduced, and energy-saving gain cannot be brought.
Suggestion 6: in scenarios #1 and #2, the measurement results from the relaxation measurement are still applicable to the EMR.
Suggestion 7: in scenario #3, when the UE configures the EMR, the UE will perform relaxation measurements.
