[0017] In order to better understand a measurement method disclosed in an embodiment of the present disclosure, a communication system applied to the embodiment of the present disclosure will be first described below.

[0018] In order to make the objectives, technical solutions and advantages of the present disclosure clearer, the following embodiments of the present disclosure will be described in more detail in combination with the drawings.

[0019] Exemplary embodiments will now be described, examples of which are illustrated in the drawings. Where the following description refers to the drawings, the same numerals in different drawings represent the same or similar elements unless otherwise noted. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as recited in the appended claims.

[0020] Referring to FIG. 1, FIG. 1 is an architecture diagram of a communication system provided by an embodiment of the present disclosure. The communication system may include, but is not limited to, one network device and one terminal device. The number and form of devices shown in FIG. 1 are merely examples and are not intended to limit the embodiment of the present disclosure, and the application of the implementation may include two or more network devices and two or more terminal devices. The communication system shown in FIG. 1 is exemplified by including one network device 101 and one terminal device 102.

[0021] It should be noted that the technical solutions of the embodiments of the present disclosure may be applied to various communication systems, such as long term evolution (LTE) systems, 5th generation (5G) mobile communication systems, 5G new radio (NR) systems, or other future new mobile communication systems.

[0022] The network device 101 in the embodiment of the present disclosure is an entity for transmitting and receiving signals on the network side. For example, the network device 101 may be an evolved base station (eNB), a transmission reception point (TRP), a next generation base station (gNB) in an NR system, a base station in other future mobile communication systems, or an access point in a wireless fidelity (WiFi) system. The embodiment of the present disclosure does not limit the specific technology and the specific device form used for the network device. The network device provided by the embodiment of the present disclosure may be composed of a central unit (CU) and a distributed unit (DU), where the CU is also called a control unit, and the protocol layer of the network device, for example, a base station, can be divided by using the CU-DU structure, and some functions of the protocol layer are centrally controlled by the CU, and the remaining part or all of the protocol layer functions are distributed in the DU, and the DU is centrally controlled by the CU.

[0023] The terminal device 102 in the embodiment of the present disclosure is an entity for transmitting and receiving signals on the user side, for example, a mobile phone. The terminal device may be called a terminal device (terminal), a user device (user equipment, UE), a mobile station (MS), a mobile terminal device (MT), etc. The terminal device may be an automobile with a communication function, a smart car, a mobile phone, a wearable device, a tablet (Pad), a personal computer equipped with a wireless transmission and reception function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, a wireless terminal device in a smart home, etc. The embodiment of the present disclosure does not limit the specific technology and the specific device form used for the terminal device.

[0024] In the above communication system, for a terminal device that satisfies the mitigation criteria, for example, a terminal device in a stationary state (or low mobility state) and / or in a good channel state, the terminal device can perform RLM (radio link monitor), BFD (beam failure detection), and RRM (radio resource management) mitigation mechanisms. For example, a terminal device that satisfies the mitigation criteria can extend the measurement interval for periodically measuring a downlink reference signal, thereby reducing the power consumption of the terminal device and extending the battery life of the terminal device. Therefore, it is extremely important how to realize the terminal device determining whether it can perform a mitigation mechanism by detecting an event triggered by the terminal device.

[0025] Here, 1. RLM mitigation mechanism: The RLM principle is as follows:

[0026] A terminal device in a radio resource control (RRC) connected (RRC_CONNECTED) state can monitor downlink radio link quality and determine whether the terminal device and the serving cell are in a downlink synchronized state (IS) or out-of-sync state (OOS) by measuring a downlink reference signal (RLM-RS) (e.g., SSB (synchronization signal and PBCH (physical broadcast channel) block)-RS and / or CSI (channel-state information)-RS) that measures a serving cell (e.g., SpCell (special Cell) in an active BWP (bandwidth part)). A specific manner of this process is as follows:

[0027] The terminal device periodically measures each RLM-RS and compares the measured value (SINR (signal to interference plus noise ratio) value) with the synchronization threshold (Q in ) and asynchronous threshold (Q out ) to determine the IS / OOS state of the terminal device, and the physical layer reports the determined IS / OOS state to the upper layer.

[0028] Specifically, the asynchronous out-of-sync evaluation period T Evaluate_out Within the time limit, the measurement value exceeds the asynchronous threshold Q out Evaluate whether the measured values ​​are lower than Q out If it is lower, L1 (physical layer) reports an OOS indication to the upper layer and the in-sync evaluation period T Evaluate_in Within the synchronization threshold Q in If one of the measurements is higher than Q in If so, L1 reports an IS indication to upper layers.

[0029] The upper layer determines the next action based on the reported OOS / IS indication, i.e., if the OOS counter records that the physical layer has continuously reported N310 OOS indications, the terminal device starts the RLF (radio link failure) timer T310 set by the network device; if the IS counter records that the physical layer has continuously reported N311 IS indications, the terminal device stops timing T310; if T310 expires, the terminal device reports RLF to the network device.

[0030] R17 introduces a mitigation mechanism for RLM, i.e., for a terminal device that meets the mitigation criteria, e.g., for a terminal device that is in a stationary state and / or has a good channel state, the terminal device performs an RLM mitigation mechanism, e.g., the measurement interval during which the terminal device periodically measures each RLM-RS may be extended.

[0031] 2. RRM mitigation mechanism R17 introduces a mitigation mechanism for RRM, that is, for a terminal device in a connected state that satisfies the criteria, the terminal device performs an RRM mitigation mechanism, for example, the terminal device may extend the measurement interval at which it periodically measures.

[0032] In response to the above problems, the present disclosure provides a measurement method and apparatus.

[0033] It should be noted that the communication system described in the embodiments of the present disclosure is intended to more clearly explain the technical solutions of the embodiments of the present disclosure, and is not intended to limit the technical solutions provided by the embodiments of the present disclosure. As can be understood by those skilled in the art, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present disclosure can also be applied to similar technical challenges.

[0034] The measurement method and device provided by the present disclosure will be described in detail below in combination with the drawings.

[0035] Please refer to Fig. 2, which is a flowchart of a measurement method provided by an embodiment of the present disclosure, which can be performed by a terminal device in the communication system shown in Fig. 1.

[0036] As shown in FIG. 2, the measurement method may include, but is not limited to, the following steps 201-202.

[0037] Step 201, measurements of target measurements including RLM measurements and / or RRM measurements are obtained.

[0038] In the embodiment of the present disclosure, the terminal device may perform target measurement to obtain a measurement value of the target measurement, where the target measurement may include an RLM measurement and / or an RRM measurement.

[0039] Preferably, if the target measurement is an RLM measurement, the measurement value may be the SINR value of the downlink RLM-RS, and if the target measurement is an RRM measurement, the measurement value may be the signal strength of the serving cell reference signal, for example RSRP (Reference Signal Receiving Power).

[0040] Step 202: determining a target event triggered by the terminal device based on the measurement value and reference information corresponding to the target measurement, where the target event includes entering or exiting a mitigation event.

[0041] In an embodiment of the present disclosure, the terminal device can determine a target event that it has triggered based on a measurement value and reference information corresponding to the target measurement, where the target event includes entering or exiting a mitigation event.

[0042] In addition, when the target measurements are different, the corresponding reference information may be different, and the reference information corresponding to the target measurements and the measurement values ​​of the target measurements can be used to determine the target events triggered by the terminal device, so as to improve the accuracy and reliability of the target event determination results.

[0043] The measurement method of the embodiment of the present disclosure obtains a measurement value of a target measurement, where the target measurement includes an RLM measurement and / or an RRM measurement, and determines a target event state triggered by a terminal device based on the measurement value and reference information corresponding to the target measurement, where the target event includes entering a mitigation event or exiting from the mitigation event. This can realize the terminal device to effectively determine whether the terminal device triggers entering a mitigation event based on the measurement value of the target measurement and the reference information corresponding to the target measurement, so that when the terminal device triggers entering a mitigation event, the terminal device can report the entry into the mitigation event to the network device, thereby performing a mitigation mechanism to improve the battery life of the terminal device. In addition, using the reference information corresponding to the target measurement and the measurement value of the target measurement to determine whether the terminal device triggers entering a mitigation event or exiting from the mitigation event can improve the accuracy and reliability of the event determination result.

[0044] Referring to Fig. 3, Fig. 3 is a flow chart of another measurement method provided by an embodiment of the present disclosure. The measurement method can be performed by a terminal device in the communication system shown in Fig. 1. The measurement method can be performed alone, or can be performed in combination with any one of the embodiments of the present disclosure or possible implementation forms in the embodiments, or can be performed together with any one of the technical solutions of the related art.

[0045] As shown in FIG. 3, the measurement method may include, but is not limited to, steps 301-302.

[0046] Step 301, perform a target measurement on a downlink reference signal of a serving cell of a terminal device to obtain a measurement value, where the target measurement is an RLM measurement and / or an RRM measurement.

[0047] In an embodiment of the present disclosure, the downlink reference signal may include a downlink reference signal of a primary serving cell and / or a downlink reference signal of at least one secondary serving cell.

[0048] In the embodiment of the present disclosure, when the target measurement is an RLM measurement, the downlink reference signal may be an RLM-RS, such as an SSB-RS and / or a CSI-RS. The downlink RLM-RS of the serving cell of the terminal device may be measured, and the measurement value obtained by the measurement may be an SINR.

[0049] In the embodiment of the present disclosure, when the target measurement is an RRM measurement, the downlink reference signal may be SSB-RS and / or CSI-RS. The downlink reference signal of the serving cell of the terminal device may be measured, and the measurement result may be RSRP.

[0050] Step 302: Determine a target event to be triggered by the terminal device based on the measurement value and the criteria information sent from the network device, where the target event includes entering or exiting a mitigation event.

[0051] In the embodiment of the present disclosure, the reference information may be transmitted by a network device, for example, the network device may configure the reference information through an RRC message.

[0052] In an embodiment of the present disclosure, the terminal device may determine a target event to be triggered by the terminal device based on the measurement value and the criteria information sent from the network device, where the target event may include entering or exiting a mitigation event.

[0053] In any one embodiment of the present disclosure, the reference information transmitted from the network device may be applicable to a primary serving cell and / or a secondary serving cell.

[0054] As an example, a network device can send one set of reference information to the terminal device, and the only one set of reference information is applicable to all serving cells connected to the terminal device, i.e., all serving cells connected to the terminal device share the set of reference information.

[0055] As another example, the network device may send multiple sets of reference information to the terminal device, and different reference information may be applied to different serving cells. For example, the network device may set reference information for each MCG (Master Cell Group) and SCG (Secondary Cell Group) connected to the terminal device, for example, the MN (Master Node) and the SN (Secondary Node) each send reference information to the terminal device, where the network device sets the reference information for the MCG and applies to the primary serving cell (PCell), i.e., the terminal device may determine the target event triggered by the terminal device based on the reference information set by the network device for the MCG when measuring the reference signal of the primary serving cell. Similarly, the reference information set by the network device for the SCG may be applied to the secondary serving cell (secondary cell, Scell), for example, applied to the primary secondary serving cell (primary SCG cell, PScell), i.e., the terminal device may determine the target event triggered by the terminal device based on the reference information set by the network device for the SCG when measuring the reference signal of the secondary serving cell.

[0056] The measurement method of the embodiment of the present disclosure obtains a measurement value of a target measurement, where the target measurement includes an RLM measurement and / or an RRM measurement, and determines a target event state triggered by a terminal device based on the measurement value and reference information corresponding to the target measurement, where the target event includes entering a mitigation event or exiting from the mitigation event. This can realize the terminal device to effectively determine whether the terminal device triggers entering a mitigation event based on the measurement value of the target measurement and the reference information corresponding to the target measurement, so that when the terminal device triggers entering a mitigation event, the terminal device can report the entry into the mitigation event to the network device, thereby performing a mitigation mechanism to improve the battery life of the terminal device. In addition, using the reference information corresponding to the target measurement and the measurement value of the target measurement to determine whether the terminal device triggers entering a mitigation event or exiting from the mitigation event can improve the accuracy and reliability of the event determination result.

[0057] It should be noted that these possible implementations described above may be implemented alone or in combination, and the embodiments of the present disclosure are not limited thereto.

[0058] Referring to Fig. 4, Fig. 4 is a flowchart of another measurement method provided by an embodiment of the present disclosure. The measurement method may be performed by a terminal device in the communication system shown in Fig. 1. The measurement method may be performed alone, or may be performed in combination with any one of the embodiments of the present disclosure or possible implementation forms in the embodiments, or may be performed together with any one of the technical solutions of the related art.

[0059] As shown in FIG. 4, the measurement method may include the following steps 401 to 403.

[0060] Step 401, obtain a measurement value of a target measurement.

[0061] Here, the target measurement includes an RLM measurement and / or an RRM measurement, and the measurement value includes at least one first RSRP obtained by performing at least one measurement on a downlink reference signal within a target period in the reference information corresponding to the target measurement, or includes at least one first RSRP obtained by measuring at least one downlink reference signal within the target period.

[0062] In an embodiment of the present disclosure, the reference information set by the network device may include a target period, and the terminal device may perform at least one measurement on a downlink reference signal within the target period to obtain at least one measurement value, which is referred to in the present disclosure as at least one first RSRP.

[0063] As an example, the terminal device may perform one measurement on the downlink reference signal within the target period to obtain one first RSRP.

[0064] As another example, the terminal device may measure the downlink reference information multiple times within the target period to obtain multiple first RSRPs.

[0065] In an embodiment of the present disclosure, the terminal device may also measure at least one downlink reference signal within the target time period to obtain at least one first RSRP.

[0066] As an example, the terminal device may measure one downlink reference signal at least once within the target time period to obtain at least one first RSRP.

[0067] As another example, the terminal device may perform at least one measurement of a plurality of downlink reference signals within a target time period to obtain a plurality of first RSRPs.

[0068] Step 402, determining a first difference between at least one first RSRP and a corresponding reference value, where the reference value corresponding to the first RSRP is obtained by measuring the first RSRP before the terminal device measures the first RSRP.

[0069] In an embodiment of the present disclosure, each first RSPR has a corresponding reference value, and the reference values ​​and the first RSPR have a one-to-one correspondence relationship, and the reference value corresponding to the first RSRP may be an RSRP obtained by measuring the first RSRP before the terminal device measures the first RSRP, for example, the reference value corresponding to the first RSRP may be an RSRP obtained in the closest measurement before the terminal device measures the first RSRP.

[0070] In an embodiment of the present disclosure, for any one first RSRP, an RSRP measured by a terminal device before measuring the first RSRP may be obtained, which is described as a reference value in the present disclosure.

[0071] In an embodiment of the present disclosure, for each first RSRP, a difference between the first RSRP and a corresponding reference value can be determined, which is referred to as a first difference in the present disclosure. For example, the first difference may be determined by subtracting the corresponding reference value from the first RSRP and obtaining the difference, or the first difference may be determined by subtracting the corresponding first RSRP from the reference value and obtaining the difference.

[0072] Step 403, in response to the first differences corresponding to at least one first RSRP being all smaller than a first difference threshold in the reference information, determining that the target event triggered by the terminal device is entering a mitigation event.

[0073] In an embodiment of the present disclosure, the reference information set by the network device may further include a first difference threshold, which is used to characterize the movement speed of the terminal device, i.e., to determine whether the terminal device is in a stationary state or a low-movement state.

[0074] For example, the network device may set the target period and the first difference threshold by an RRC message. Optionally, the target period may be set to T SearchDeltaP Mark as , and set the first difference threshold as S SearchDeltaP can be marked as

[0075] In an embodiment of the present disclosure, if the first differences corresponding to all the first RSRPs are all smaller than the first difference threshold in the reference information, it can be determined that the target event triggered by the terminal device is an entry into a mitigation event, that is, it is determined that the terminal device meets the mitigation entry criteria.

[0076] In addition, if the first differences corresponding to all the first RSRPs are all smaller than the first difference threshold, it indicates that the movement speed of the terminal device is low, and at this time, the entry into the mitigation event may be referred to as a low mobility event, and correspondingly, the mitigation entry criterion may be referred to as a low mobility criterion.

[0077] In any one of the embodiments of the present disclosure, a reference value corresponding to each first RSRP may be updated. For example, when a terminal device performs cell switching, a corresponding reference value may be updated based on each first RSRP. For example, for each first RSRP, a reference value corresponding to the first RSRP may be updated to the first RSRP. Or, for each first RSRP, it may be determined whether a difference obtained by subtracting a corresponding reference value from the first RSRP is greater than a third difference threshold. If the difference obtained by subtracting a corresponding reference value from the first RSRP is greater than the third difference threshold, a reference value corresponding to the first RSRP may be updated based on the first RSRP. For example, the reference value corresponding to the first RSRP is updated to the first RSRP, and if the difference obtained by subtracting a corresponding reference value from the first RSRP is equal to or greater than the third difference threshold, a reference value corresponding to the first RSRP may not be updated, or a target period (T SearchDeltaP), it may be determined whether the first difference of each first RSRP is smaller than a first difference threshold, and if the first difference of a certain first RSRP is greater than or equal to the first difference threshold, the corresponding reference value may be updated based on the first RSRP. For example, the reference value corresponding to the first RSRP may be updated to the first RSRP, and if the first difference of a certain first RSRP is smaller than the first difference threshold, the reference value corresponding to the first RSRP may not be updated.

[0078] Here, the third difference threshold is preset, for example, the third difference threshold may be set by a network device, or the third difference threshold may be agreed upon by a protocol, and the present disclosure is not limited thereto. For example, the third difference threshold may be 0.

[0079] The measurement method of the embodiment of the present disclosure obtains a measurement value of a target measurement, where the target measurement includes an RLM measurement and / or an RRM measurement, and determines a target event state triggered by a terminal device based on the measurement value and reference information corresponding to the target measurement, where the target event includes entering a mitigation event or exiting from the mitigation event. This can realize the terminal device to effectively determine whether the terminal device triggers entering a mitigation event based on the measurement value of the target measurement and the reference information corresponding to the target measurement, so that when the terminal device triggers entering a mitigation event, the terminal device can report the entry into the mitigation event to the network device, thereby performing a mitigation mechanism to improve the battery life of the terminal device. In addition, using the reference information corresponding to the target measurement and the measurement value of the target measurement to determine whether the terminal device triggers entering a mitigation event or exiting from the mitigation event can improve the accuracy and reliability of the event determination result.

[0080] It should be noted that these possible implementations described above may be implemented alone or in combination, and the embodiments of the present disclosure are not limited thereto.

[0081] In any one embodiment of the present disclosure, a protocol may be implemented to define an event Event R1, including entering and exiting a mitigation event.

[0082] As an example, for entering a mitigation event, e.g., for a low mobility event, Event R1-1 may be marked, where Event R1-1 can be determined by a low mobility criterion. SearchDeltaP The measured value Srxlev detected by the terminal device and the reference value Srxlev Ref The difference between the first difference threshold S SearchDeltaP If it is smaller, the variation of the reference signal is not large, and at this time, it can be determined that the terminal device is in a low mobility state.

[0083] Example 1: (Srxlev Ref -Srxlev) SearchDeltaP If the low-mobility criterion is met, it may be determined that the target event triggered by the terminal device is an entry into a mitigation event or a low-mobility event.

[0084] Here, the unit of the measured value Srxlev is dB, and the unit of the reference value Srxlev Ref is dB.

[0085] Here, when any one of the following conditions is satisfied, the reference value is set as the measured value. (1) The terminal device is switched to a new serving cell. (2) Srxlev-Srxlev Ref >0. (3) Target period T SearchDeltaP Within, (Srxlev Ref -Srxlev) SearchDeltaP The low mobility criterion is not met.

[0086] ​​Referring to Fig. 5, Fig. 5 is a flowchart of another measurement method provided by an embodiment of the present disclosure. The measurement method may be performed by a terminal device in the communication system shown in Fig. 1. The measurement method may be performed alone, or may be performed in combination with any one of the embodiments of the present disclosure or possible implementation forms in the embodiments, or may be performed together with any one of the technical solutions of the related art.

[0087] As shown in FIG. 5, the measurement method may include, but is not limited to, the following steps 501 to 504.

[0088] Step 501, obtain a measurement value of a target measurement.

[0089] Here, the target measurement includes an RLM measurement and / or an RRM measurement, and the measurement is performed within a target period (T SearchDeltaP ) or at least one first RSRP obtained by measuring a downlink reference signal at least once within a target period (T SearchDeltaP The measurement value includes at least one first RSRP obtained by measuring at least one downlink reference signal within a set time length (T1) after the target period. The measurement value also includes a plurality of second RSRPs obtained by measuring the downlink reference signal a plurality of times within a set time length (T1) after the target period, or a plurality of second RSRPs obtained by measuring a plurality of downlink reference signals within the set time length (T1).

[0090] In the embodiment of the present disclosure, step 501 can be implemented in any one of the manners in each embodiment of the present disclosure, and the embodiment of the present disclosure is not limited thereto, and detailed description thereof will be omitted.

[0091] In an embodiment of the present disclosure, the set time length is preset, for example, the set time length may be set by a network device, or the set time length may be promised by a protocol, and the present disclosure is not limited thereto. Optionally, the set time length is marked as T1.

[0092] In an embodiment of the present disclosure, the terminal device further selects a target period (T SearchDeltaP ) multiple measurements can be made on the downlink reference signal within a set time length (T1) after the set time length (T1) to obtain multiple measurement values, which are described in this disclosure as multiple second RSRPs, or the terminal device can perform at least one measurement on multiple downlink reference signals within the set time length (T1) to obtain multiple second RSRPs.

[0093] Step 502, determining a first difference between at least one first RSRP and a corresponding reference value, where the reference value corresponding to the first RSRP is obtained by measuring the first RSRP before the terminal device measures the first RSRP.

[0094] In the embodiment of the present disclosure, step 502 can be implemented in any one of the manners in each embodiment of the present disclosure, and the embodiment of the present disclosure is not limited thereto, and detailed description thereof will be omitted.

[0095] Step 503: in response to the first differences corresponding to at least one first RSRP being smaller than a first difference threshold in the reference information, determining second differences between a plurality of second RSRPs and corresponding reference values, where the second RSRPs and the corresponding reference values ​​are obtained by measuring the second RSRPs before the terminal device measures the second RSRPs.

[0096] In an embodiment of the present disclosure, each second RSPR has a corresponding reference value, the reference value and the second RSPR have a one-to-one correspondence relationship, and the reference value corresponding to the second RSRP may be an RSRP obtained by measuring the second RSRP before the terminal device measures the second RSRP, for example, the reference value corresponding to the second RSRP is an RSRP obtained in the closest measurement before the terminal device measures the second RSRP.

[0097] In an embodiment of the present disclosure, when the terminal device determines that all of the first differences corresponding to the first RSRPs are smaller than the first difference threshold in the reference information, the terminal device can further obtain a reference value corresponding to each second RSRP.

[0098] In an embodiment of the present disclosure, for each second RSRP, the terminal device can determine a difference between the second RSRP and a corresponding reference value, which is referred to as a second difference in the present disclosure. For example, the terminal device can subtract the corresponding reference value from the second RSRP to obtain the second difference, or the terminal device can subtract the corresponding second RSRP from the reference value to obtain the second difference.

[0099] Step 504, in response to the second differences corresponding to the plurality of second RSRPs all being less than the first difference threshold, determining that the target event triggered by the terminal device is entering a mitigation event.

[0100] In an embodiment of the present disclosure, if the second differences corresponding to each second RSRP are all less than the first difference threshold, it can be determined that the target event is an entry into a mitigation event, and it is determined that the terminal device meets the mitigation entry criteria.

[0101] Furthermore, if the second differences corresponding to all the second RSRPs are all smaller than the first difference threshold, it indicates that the movement speed of the terminal device is low, and at this time, the entry into the mitigation event may be referred to as a low mobility event.

[0102] In any one of the embodiments of the present disclosure, a reference value corresponding to each first RSRP may be updated. For example, when a terminal device performs cell switching, a corresponding reference value may be updated based on each first RSRP. For example, for each first RSRP, a reference value corresponding to the first RSRP may be updated to the first RSRP. Or, for each first RSRP, it may be determined whether a difference obtained by subtracting a corresponding reference value from the first RSRP is greater than a third difference threshold. If the difference obtained by subtracting a corresponding reference value from the first RSRP is greater than the third difference threshold, a reference value corresponding to the first RSRP may be updated based on the first RSRP. For example, the reference value corresponding to the first RSRP is updated to the first RSRP, and if the difference obtained by subtracting a corresponding reference value from the first RSRP is equal to or greater than the third difference threshold, a reference value corresponding to the first RSRP may not be updated, or a target period (T SearchDeltaP ), it may be determined whether the first difference of each first RSRP is smaller than a first difference threshold, and if the first difference of a certain first RSRP is greater than or equal to the first difference threshold, the corresponding reference value may be updated based on the first RSRP. For example, the reference value corresponding to the first RSRP may be updated to the first RSRP, and if the first difference of a certain first RSRP is smaller than the first difference threshold, the reference value corresponding to the first RSRP may not be updated.

[0103] Similarly, when the terminal device performs cell switching, it may update the corresponding reference value according to each second RSRP, for example, for each second RSRP, it may update the reference value corresponding to the second RSRP to the second RSRP; or, for each second RSRP, it may determine whether the difference obtained by subtracting the corresponding reference value from the second RSRP is greater than a third difference threshold, and if the difference obtained by subtracting the corresponding reference value from the second RSRP is greater than the third difference threshold, it may update the corresponding reference value according to the second RSRP, for example, it may update the reference value corresponding to the second RSRP to the second RSRP. If the difference obtained by subtracting the corresponding reference value from the second RSRP is less than the third difference threshold, there is no need to update the reference value corresponding to the second RSRP, and it may be determined within a set time length (T1) whether the second difference of each second RSRP is less than the first difference threshold, and if the second difference of a certain second RSRP is greater than or equal to the first difference threshold, the corresponding reference value may be updated based on the second RSRP, for example, the reference value corresponding to the second RSRP is updated to the second RSRP, and if the difference between the two of a certain second RSRP is less than the first difference threshold, there is no need to update the reference value corresponding to the second RSRP.

[0104] The measurement method of the embodiment of the present disclosure obtains a measurement value of a target measurement, where the target measurement includes an RLM measurement and / or an RRM measurement, and determines a target event state triggered by a terminal device based on the measurement value and reference information corresponding to the target measurement, where the target event includes entering a mitigation event or exiting from the mitigation event. This can realize the terminal device to effectively determine whether the terminal device triggers entering a mitigation event based on the measurement value of the target measurement and the reference information corresponding to the target measurement, so that when the terminal device triggers entering a mitigation event, the terminal device can report the entry into the mitigation event to the network device, thereby performing a mitigation mechanism to improve the battery life of the terminal device. In addition, using the reference information corresponding to the target measurement and the measurement value of the target measurement to determine whether the terminal device triggers entering a mitigation event or exiting from the mitigation event can improve the accuracy and reliability of the event determination result.

[0105] It should be noted that these possible implementations described above may be implemented alone or in combination, and the embodiments of the present disclosure are not limited thereto.

[0106] In any one embodiment of the present disclosure, a protocol may be implemented to define an event Event R1, including entering and exiting a mitigation event.

[0107] As an example, for entering a mitigation event, e.g., for a low mobility event, Event R1-1 may be marked, where Event R1-1 can be determined by a low mobility criterion. SearchDeltaP The measured value Srxlev detected by the terminal device and the reference value Srxlev Ref The difference between the first difference threshold S SearchDeltaP If it is smaller, the variation of the reference signal is not large, and at this time, it can be determined that the terminal device is in a low mobility state.

[0108] Furthermore, within the set time length T1, the measured value Srxlev detected by the terminal device and the reference value Srxlev Ref The difference between the first difference threshold S SearchDeltaP It may be determined whether the difference is less than a first difference threshold S SearchDeltaP If it is smaller, it determines that the target event triggered by the terminal device is an entry into a mitigation event or a low mobility event.

[0109] Example 2: The judgment condition for Event R1-1 is that T SearchDeltaP With units of (Srxlev Ref -Srxlev) SearchDeltaP If the low-mobility criterion is met, determine that the target event triggered by the terminal device is an entry into a mitigation event or a low-mobility event.

[0110] Here, the unit of the measured value Srxlev is dB, and the reference value Srxlev Ref The unit is dB.

[0111] Here, when any one of the following conditions is satisfied, the reference value is set as the measured value. (1) The terminal device is switched to a new serving cell. (2) Srxlev-Srxlev Ref >0. (3) Target period T SearchDeltaP Within, (Srxlev Ref -Srxlev) SearchDeltaP The low mobility criterion is not met.

[0112] ​​Referring to Fig. 6, Fig. 6 is a flowchart of another measurement method provided by an embodiment of the present disclosure. The measurement method may be performed by a terminal device in the communication system shown in Fig. 1. The measurement method may be performed alone, or may be performed in combination with any one of the embodiments of the present disclosure or possible implementation forms in the embodiments, or may be performed together with any one of the technical solutions of the related art.

[0113] As shown in FIG. 6, the measurement method may include, but is not limited to, the following steps 601 to 603.

[0114] Step 601, obtain a measurement value of a target measurement.

[0115] Here, the target measurement includes an RLM measurement and / or an RRM measurement, and the measurement value includes at least one first RSRP obtained by performing at least one measurement on a downlink reference signal within a target period in the reference information corresponding to the target measurement, or includes at least one first RSRP obtained by measuring at least one downlink reference signal within the target period.

[0116] Step 602, determining a first difference between at least one first RSRP and a corresponding reference value, where the reference value corresponding to the first RSRP is obtained by measuring the first RSRP before the terminal device measures the first RSRP.

[0117] In the embodiment of the present disclosure, steps 601 to 602 can be implemented by any one of the methods in the embodiments of the present disclosure, but the embodiments of the present disclosure are not limited thereto, and detailed description thereof will be omitted.

[0118] Step 603, in response to the presence of at least one first difference corresponding to the first RSRP being equal to or greater than the second difference threshold in the reference information, it may be determined that the target event triggered by the terminal device is an exit from a mitigation event.

[0119] In an embodiment of the present disclosure, the reference information transmitted from the network device is a target period (T SearchDeltaP ), but may further include a second difference threshold, which is used to characterize the moving speed of the terminal device, i.e., to determine whether the terminal device is in a stationary state or a low-movement state.

[0120] Here, the second difference threshold and the first difference threshold may be the same or different, for example, the second difference threshold can be determined based on the first difference threshold and the correction offset value.

[0121] As an example, the network device may determine the target period and the second difference threshold by an RRC message. Optionally, the target period may be set to T SearchDeltaP Let the second difference threshold be S SearchDeltaP ' may be marked as

[0122] In an embodiment of the present disclosure, if there is at least one first difference corresponding to a first RSRP that is equal to or greater than a second difference threshold in the reference information, it can be determined that the target event triggered by the terminal device is an exit from a mitigation event, i.e., it can be determined that the terminal device meets the exit from the mitigation criteria.

[0123] In addition, if there is at least one first difference corresponding to a first RSRP that is greater than or equal to the second difference threshold, this indicates that the mobility speed of the terminal device is not low, in which case the exit from the mitigation event may be referred to as a non-low mobility event or a high mobility event.

[0124] In any one of the embodiments of the present disclosure, a reference value corresponding to each first RSRP may be updated. For example, when a terminal device performs cell switching, a corresponding reference value may be updated based on each first RSRP. For example, for each first RSRP, a reference value corresponding to the first RSRP may be updated to the first RSRP. Or, for each first RSRP, it may be determined whether a difference obtained by subtracting a corresponding reference value from the first RSRP is greater than a third difference threshold. If the difference obtained by subtracting a corresponding reference value from the first RSRP is greater than the third difference threshold, a reference value corresponding to the first RSRP may be updated based on the first RSRP. For example, the reference value corresponding to the first RSRP is updated to the first RSRP, and if the difference obtained by subtracting a corresponding reference value from the first RSRP is equal to or greater than the third difference threshold, a reference value corresponding to the first RSRP may not be updated, or a target period (T SearchDeltaP ), it can be determined whether the first difference of each first RSRP is smaller than the second difference threshold, and if the first difference of a first RSRP is smaller than the second difference threshold, the corresponding reference value can be updated based on the first RSRP, for example, the reference value corresponding to the first RSRP can be updated to the first RSRP, and if the first difference of a first RSRP is equal to or greater than the second difference threshold, the reference value corresponding to the first RSRP does not need to be updated.

[0125] The measurement method of the embodiment of the present disclosure obtains a measurement value of a target measurement, where the target measurement includes an RLM measurement and / or an RRM measurement, and determines a target event state triggered by a terminal device based on the measurement value and reference information corresponding to the target measurement, where the target event includes entering a mitigation event or exiting from the mitigation event. This can realize the terminal device to effectively determine whether the terminal device triggers entering a mitigation event based on the measurement value of the target measurement and the reference information corresponding to the target measurement, so that when the terminal device triggers entering a mitigation event, the terminal device can report the entry into the mitigation event to the network device, thereby performing a mitigation mechanism to improve the battery life of the terminal device. In addition, using the reference information corresponding to the target measurement and the measurement value of the target measurement to determine whether the terminal device triggers entering a mitigation event or exiting from the mitigation event can improve the accuracy and reliability of the event determination result.

[0126] It should be noted that these possible implementations described above may be implemented alone or in combination, and the embodiments of the present disclosure are not limited thereto.

[0127] In any one embodiment of the present disclosure, a protocol may be implemented to define an event Event R1, including entering and exiting a mitigation event.

[0128] As an example, an exit from a mitigation event, e.g., a non-low mobility event or a high mobility event, can be marked as Event R1-2, and Event R1-2 can be determined based on a low mobility criterion. SearchDeltaP The measured value Srxlev detected by the terminal device and the reference value Srxlev Ref The difference between the second difference threshold S SearchDeltaPIf it is greater than , it indicates that the variation range of the reference signal is large, and at this time, it can be determined that the terminal device is not in a low mobility state.

[0129] Example 3: (Srxlev Ref -Srxlev)>S SearchDeltaP ' is satisfied, it can be determined that the target event triggered by the terminal device is an exit from a mitigation event or a non-low mobility event or a high mobility event.

[0130] Here, the unit of the measured value Srxlev is dB, and the reference value Srxlev Ref The unit is dB.

[0131] Here, when any one of the following conditions is satisfied, the reference value is set as the measured value. (1) The terminal device is switched to a new serving cell. (2) Srxlev-Srxlev Ref >0. (3) Target period T SearchDeltaP Within, (Srxlev Ref -Srxlev) SearchDeltaP The low mobility criterion is not met.

[0132] Referring to Fig. 7, Fig. 7 is a flowchart of another measurement method provided by an embodiment of the present disclosure. The measurement method may be performed by a terminal device in the communication system shown in Fig. 1. The measurement method may be performed alone, or may be performed in combination with any one of the embodiments of the present disclosure or possible implementation forms in the embodiments, or may be performed together with any one of the technical solutions of the related art.

[0133] As shown in FIG. 7, the measurement method may include the following steps 701 to 704.

[0134] Step 701, obtain a measurement value of a target measurement.

[0135] ​Here, the target measurement includes an RLM measurement and / or an RRM measurement, and the measurement includes at least one first RSRP obtained by performing at least one measurement on a downlink reference signal within a target period in the reference information corresponding to the target measurement, or includes at least one first RSRP obtained by measuring at least one downlink reference signal within the target period, and further includes a plurality of second RSRPs obtained by measuring the downlink reference signal a plurality of times within a set time length after the target period, or further includes a plurality of second RSRPs obtained by measuring a plurality of downlink reference signals within the set time length.

[0136] Step 702, determining a first difference between at least one first RSRP and a corresponding reference value, where the reference value corresponding to the first RSRP is obtained by measuring the first RSRP before the terminal device measures the first RSRP.

[0137] In the embodiment of the present disclosure, steps 701 to 702 can be implemented by any one of the methods in the embodiments of the present disclosure, but the embodiment of the present disclosure is not limited thereto, and detailed description thereof will be omitted.

[0138] Step 703, in response to the presence of at least one first difference corresponding to the first RSRP being equal to or greater than a second difference threshold in the reference information, determining second differences between the plurality of second RSRPs and corresponding reference values, where the reference value corresponding to the second RSRPs is obtained by measuring the second RSRPs before the terminal device measures the second RSRPs.

[0139] Here, for an explanation of the reference value corresponding to the second RSRP, please refer to any one of the embodiments of the present disclosure, and detailed explanation will be omitted here.

[0140] In an embodiment of the present disclosure, when there is at least one first difference corresponding to a first RSRP that is equal to or greater than a second difference threshold in the reference information, a reference value corresponding to each second RSRP may be further obtained, and a second difference between the second RSRP and the corresponding reference value may be determined.

[0141] Step 704, in response to there being at least one second difference corresponding to the second RSRP that is greater than or equal to the second difference threshold, it may be determined that the target event triggered by the terminal device is an exit from the mitigation event.

[0142] In an embodiment of the present disclosure, if there is at least one second difference corresponding to a second RSRP that is equal to or greater than a second difference threshold in the reference information, it can be determined that the target event triggered by the terminal device is an exit from a mitigation event, i.e., it can be determined that the terminal device meets the exit from the mitigation criteria.

[0143] In addition, if there is at least one second difference corresponding to a second RSRP that is greater than or equal to the second difference threshold, this indicates that the mobility speed of the terminal device is not low, in which case the exit from the mitigation event may be referred to as a non-low mobility event or a high mobility event.

[0144] In any one of the embodiments of the present disclosure, a reference value corresponding to each first RSRP may be updated. For example, when a terminal device performs cell switching, a corresponding reference value may be updated based on each first RSRP. For example, for each first RSRP, a reference value corresponding to the first RSRP may be updated to the first RSRP. Or, for each first RSRP, it may be determined whether a difference obtained by subtracting a corresponding reference value from the first RSRP is greater than a third difference threshold. If the difference obtained by subtracting a corresponding reference value from the first RSRP is greater than the third difference threshold, a reference value corresponding to the first RSRP may be updated based on the first RSRP. For example, the reference value corresponding to the first RSRP is updated to the first RSRP, and if the difference obtained by subtracting a corresponding reference value from the first RSRP is equal to or greater than the third difference threshold, a reference value corresponding to the first RSRP may not be updated, or a target period (T SearchDeltaP), it can be determined whether the first difference of each first RSRP is smaller than the second difference threshold, and if the first difference of a first RSRP is smaller than the second difference threshold, the corresponding reference value can be updated based on the first RSRP, for example, the reference value corresponding to the first RSRP can be updated to the first RSRP, and if the first difference of a first RSRP is equal to or greater than the first difference threshold, the reference value corresponding to the first RSRP does not need to be updated.

[0145] Similarly, when the terminal device performs cell switching, it may update the corresponding reference value according to each second RSRP, for example, for each second RSRP, it may update the reference value corresponding to the second RSRP to the second RSRP; or, for each second RSRP, it may determine whether the difference obtained by subtracting the corresponding reference value from the second RSRP is greater than a third difference threshold, and if the difference obtained by subtracting the corresponding reference value from the second RSRP is greater than the third difference threshold, it may update the corresponding reference value according to the second RSRP, for example, it may update the reference value corresponding to the second RSRP to the second RSRP. If the difference obtained by subtracting the corresponding reference value from the second RSRP is less than the third difference threshold, there is no need to update the reference value corresponding to the second RSRP, and it may be determined within a set time length (T1) whether the second difference of each second RSRP is less than the first difference threshold, and if the second difference of a certain second RSRP is greater than or equal to the first difference threshold, the corresponding reference value may be updated based on the second RSRP, for example, the reference value corresponding to the second RSRP is updated to the second RSRP, and if the difference between the two of a certain second RSRP is less than the first difference threshold, there is no need to update the reference value corresponding to the second RSRP.

[0146] The measurement method of the embodiment of the present disclosure obtains a measurement value of a target measurement, where the target measurement includes an RLM measurement and / or an RRM measurement, and determines a target event state triggered by a terminal device based on the measurement value and reference information corresponding to the target measurement, where the target event includes entering a mitigation event or exiting from the mitigation event. This can realize the terminal device to effectively determine whether the terminal device triggers entering a mitigation event based on the measurement value of the target measurement and the reference information corresponding to the target measurement, so that when the terminal device triggers entering a mitigation event, the terminal device can report the entry into the mitigation event to the network device, thereby performing a mitigation mechanism to improve the battery life of the terminal device. In addition, using the reference information corresponding to the target measurement and the measurement value of the target measurement to determine whether the terminal device triggers entering a mitigation event or exiting from the mitigation event can improve the accuracy and reliability of the event determination result.

[0147] It should be noted that these possible implementations described above may be implemented alone or in combination, and the embodiments of the present disclosure are not limited thereto.

[0148] In any one embodiment of the present disclosure, a protocol may be implemented to define an event Event R1, including entering and exiting a mitigation event.

[0149] As an example, an exit from a mitigation event, e.g., a non-low mobility event or a high mobility event, can be marked as Event R1-2, and Event R1-2 can be determined based on a low mobility criterion. SearchDeltaP The measured value Srxlev detected by the terminal device and the reference value Srxlev Ref The difference between the second difference threshold S SearchDeltaPIf it is greater than , it indicates that the variation range of the reference signal is large, and at this time, it can be determined that the terminal device is not in a low mobility state.

[0150] Furthermore, within the set time length T1, the measured value Srxlev detected by the terminal device and the reference value Srxlev Ref The difference between the second difference threshold S SearchDeltaP ', and determining whether the difference is greater than a second difference threshold S SearchDeltaP ', it may be determined that the target event triggered by the terminal device is an exit from a mitigation event or a non-low mobility event.

[0151] Example 4: The judgment condition for Event R1-2 is that T SearchDeltaP With units of (Srxlev Ref -Srxlev)>S SearchDeltaP ', it can be determined that the target event triggered by the terminal device is an exit from a mitigation event or a non-low mobility event.

[0152] Here, the unit of the measured value Srxlev is dB, and the reference value Srxlev Ref The unit is dB.

[0153] Here, when any one of the following conditions is satisfied, the reference value is set as the measured value. (1) The terminal device is switched to a new serving cell. (2) Srxlev-Srxlev Ref >0. (3) Target period T SearchDeltaP Within, (Srxlev Ref -Srxlev) SearchDeltaP The low mobility criterion is not met.

[0154] ​Referring to Fig. 8, Fig. 8 is a flowchart of another measurement method provided by an embodiment of the present disclosure. The measurement method may be performed by a terminal device in the communication system shown in Fig. 1. The measurement method may be performed alone, or may be performed in combination with any one of the embodiments of the present disclosure or possible implementation forms in the embodiments, or may be performed together with any one of the technical solutions of the related art.

[0155] As shown in FIG. 8, the measurement method may include the following steps 801 to 803.

[0156] Step 801, obtain a measurement value of a target measurement, including an RLM measurement and / or an RRM measurement, where the measurement value includes a plurality of first SINRs obtained by measuring a plurality of downlink reference signals.

[0157] In the embodiment of the present disclosure, step 801 can be implemented in any one of the manners in each embodiment of the present disclosure, and the embodiment of the present disclosure is not limited thereto, and detailed description thereof will be omitted.

[0158] In an embodiment of the present disclosure, a terminal device may perform at least one measurement on a plurality of downlink reference signals to obtain a plurality of measurement values, which may be described in the present disclosure as a plurality of first SINRs.

[0159] Step 802, a first quality threshold is determined based on threshold indication information in the reference information corresponding to the target measurement.

[0160] In an embodiment of the present disclosure, the criteria information sent from the network device may include threshold indication information, for example, the network device may set the threshold indication information through an RRC message.

[0161] In an embodiment of the present disclosure, the terminal device may determine a first quality threshold based on the threshold indication information, where the first quality threshold is used to characterize a reference signal quality.

[0162] In one possible implementation of the embodiment of the present disclosure, the threshold indication information may include a first offset, and optionally, the first offset may be marked as offset1.

[0163] In the embodiment of the present disclosure, the terminal device can determine the first quality threshold based on the first offset, for example, by adding the first offset and the first setting threshold to obtain the first quality threshold, where the first setting threshold is a threshold Q corresponding to the RLM measurement in the related art. in Or Q out may be also possible.

[0164] In another possible implementation form of the embodiment of the present disclosure, the threshold indication information may include a target threshold, and the terminal device may determine a first quality threshold based on the target threshold, for example, the target threshold may be the first quality threshold.

[0165] Step 803: in response to the plurality of first SINRs all being greater than a first quality threshold, determining that the target event is entering a mitigation event, or in response to the presence of at least one first SINR greater than the first quality threshold, determining that the target event is entering a mitigation event.

[0166] In one possible implementation form of an embodiment of the present disclosure, if the multiple first SINRs are all higher than a first quality threshold, it can be determined that the target event triggered by the terminal device is an entry into a mitigation event, i.e., it is determined that the terminal device meets the mitigation entry criteria.

[0167] In another possible implementation form of an embodiment of the present disclosure, if there is at least one first SINR greater than a first quality threshold, it can be determined that the target event triggered by the terminal device is an entry into a mitigation event, i.e., the terminal device is determined to meet the mitigation entry criteria.

[0168] It should be noted that if the first SINR is greater than the first quality threshold, it may be determined that the signal quality of the sub-signal is good, in which case the entry into the mitigation event may be referred to as a cell signal quality good event.

[0169] The measurement method of the embodiment of the present disclosure obtains a measurement value of a target measurement, where the target measurement includes an RLM measurement and / or an RRM measurement, and determines a target event state triggered by a terminal device based on the measurement value and reference information corresponding to the target measurement, where the target event includes entering a mitigation event or exiting from the mitigation event. This can realize the terminal device to effectively determine whether the terminal device triggers entering a mitigation event based on the measurement value of the target measurement and the reference information corresponding to the target measurement, so that when the terminal device triggers entering a mitigation event, the terminal device can report the entry into the mitigation event to the network device, thereby performing a mitigation mechanism to improve the battery life of the terminal device. In addition, using the reference information corresponding to the target measurement and the measurement value of the target measurement to determine whether the terminal device triggers entering a mitigation event or exiting from the mitigation event can improve the accuracy and reliability of the event determination result.

[0170] It should be noted that these possible implementations described above may be implemented alone or in combination, and the embodiments of the present disclosure are not limited thereto.

[0171] In any one embodiment of the present disclosure, a protocol contract may define an event Event R2 (including an entry into a mitigation event and an exit from a mitigation event).

[0172] As an example, the entry into a mitigation event, such as a cell signal quality good event, can be marked as Event R2-1, and Event R2-1 can be determined based on a signal quality good criterion, that is, when multiple RSs (i.e. reference signals) are configured in a serving cell, each RS can be measured, and the SINR corresponding to the measured RS is compared with a threshold to determine whether the terminal device meets the signal quality good criterion.

[0173] Example 5: All RSs have the measurement value SINR measured > First quality threshold (Q out +Offset1), determine that the terminal device meets the good signal quality criterion, and determine that the target event triggered by the terminal device is an entry into a mitigation event or a cell signal quality good event.

[0174] Example 6: Either RS ​​is a measurement value SINR measured > First quality threshold (Q out +Offset1), determine that the terminal device meets the good signal quality criterion, and determine that the target event triggered by the terminal device is an entry into a mitigation event or a cell signal quality good event.

[0175] Referring to Fig. 9, Fig. 9 is a flowchart of another measurement method provided by an embodiment of the present disclosure. The measurement method may be performed by a terminal device in the communication system shown in Fig. 1. The measurement method may be performed alone, or may be performed in combination with any one of the embodiments of the present disclosure or possible implementation forms in the embodiments, or may be performed together with any one of the technical solutions of the related art.

[0176] As shown in FIG. 9, the measurement method may include, but is not limited to, the following steps 901 to 903.

[0177] Step 901, obtain a measurement value of a target measurement, including an RLM measurement and / or an RRM measurement, where the measurement value includes a plurality of first SINRs obtained by measuring a plurality of downlink reference signals.

[0178] In the embodiment of the present disclosure, step 901 can be implemented in any one of the manners in each embodiment of the present disclosure, and the embodiment of the present disclosure is not limited thereto, and detailed description thereof will be omitted.

[0179] Step 902, a second quality threshold is determined based on threshold indication information in the reference information corresponding to the target measurement.

[0180] In an embodiment of the present disclosure, the criteria information sent from the network device may include threshold indication information, for example, the network device may set the threshold indication information through an RRC message.

[0181] In an embodiment of the present disclosure, the terminal device determines a second quality threshold based on the threshold indication information, where the second quality threshold is used to characterize the reference signal quality.

[0182] In one possible implementation of the embodiment of the present disclosure, the threshold indication information may include a second offset, and optionally mark the second offset as offset2. The terminal device can determine a second quality threshold based on the second offset, for example, by adding the second offset and the second setting threshold to obtain the second quality threshold.

[0183] Here, the second set threshold is the threshold Q corresponding to the RLM measurement in the related art. in Or Q out may be also possible.

[0184] Here, the second offset and the first offset may be the same or different, and the present disclosure is not limited thereto.

[0185] Here, the first set threshold and the second set threshold may be the same or different, and the present disclosure is not limited thereto.

[0186] In addition, the first offset set by the network device for determining whether to trigger entry into a mitigation event may be different from the second offset for determining whether to trigger exit from the mitigation event, and in this case, the first setting threshold and the second setting threshold may be the same, and the first quality threshold and the second quality threshold are different.

[0187] In another possible implementation form of the embodiment of the present disclosure, the threshold indication information may include a target threshold, and the terminal device may determine a second quality threshold based on the target threshold, for example, the target threshold may be the second quality threshold.

[0188] Step 903: In response to the presence of at least one first SINR that is equal to or less than the second quality threshold, the target event triggered by the terminal device can be determined to be an exit from a mitigation event, or in response to all of the multiple first SINRs being equal to or less than the second quality threshold, the target event is determined to be an exit from a mitigation event.

[0189] In an embodiment of the present disclosure, if there is at least one first SINR that is equal to or less than the second quality threshold, it can be determined that the target event triggered by the terminal device is an exit from the mitigation event, i.e., it can be determined that the terminal device meets the exit from the mitigation criterion. Or, if each of the first SINRs is equal to or less than the second quality threshold, it can be determined that the target event triggered by the terminal device is an exit from the mitigation event, i.e., it can be determined that the terminal device meets the exit from the mitigation criterion.

[0190] It should be noted that if the first SINR is less than or equal to the second quality threshold, it may be determined that the signal quality of the reference signal is poor, and in this case, the exit from the mitigation event is referred to as a non-cell signal quality good event or a cell signal quality poor event.

[0191] The measurement method of the embodiment of the present disclosure obtains a measurement value of a target measurement, where the target measurement includes an RLM measurement and / or an RRM measurement, and determines a target event state triggered by a terminal device based on the measurement value and reference information corresponding to the target measurement, where the target event includes entering a mitigation event or exiting from the mitigation event. This can realize the terminal device to effectively determine whether the terminal device triggers entering a mitigation event based on the measurement value of the target measurement and the reference information corresponding to the target measurement, so that when the terminal device triggers entering a mitigation event, the terminal device can report the entry into the mitigation event to the network device, thereby performing a mitigation mechanism to improve the battery life of the terminal device. In addition, using the reference information corresponding to the target measurement and the measurement value of the target measurement to determine whether the terminal device triggers entering a mitigation event or exiting from the mitigation event can improve the accuracy and reliability of the event determination result.

[0192] It should be noted that these possible implementations described above may be implemented alone or in combination, and the embodiments of the present disclosure are not limited thereto.

[0193] In any one embodiment of the present disclosure, a protocol contract may define an event Event R2 (including an entry into a mitigation event and an exit from a mitigation event).

[0194] As an example, an exit from a mitigation event, such as a non-cell signal quality good event or a cell signal quality bad event, can be marked as Event R2-2, and Event R2-2 can be determined based on a signal quality good criterion, that is, when multiple RSs (i.e., reference signals) are configured in a serving cell, each RS may be measured, and the SINR corresponding to the measured RS is compared with a threshold to determine whether the terminal device meets the signal quality good criterion.

[0195] In the seventh embodiment, if any one of the RSs has a measured SINR measured <Second quality threshold (Q out +Offset2), determine that the terminal device does not meet the good signal quality criterion, and determine that the target event triggered by the terminal device is an exit from a mitigation event or a non-cell good signal quality event or a cell bad signal quality event.

[0196] In Example 8, all RSs are measured values ​​of SINR measured <Second quality threshold (Q out +Offset2), determine that the terminal device does not meet the good signal quality criterion, and determine that the target event triggered by the terminal device is an exit from a mitigation event or a non-cell good signal quality event or a cell bad signal quality event.

[0197] Referring to Fig. 10, Fig. 10 is a flowchart of another measurement method provided by an embodiment of the present disclosure. The measurement method may be performed by a terminal device in the communication system shown in Fig. 1. The measurement method may be performed alone, or may be performed in combination with any one of the embodiments of the present disclosure or possible implementation forms in the embodiments, or may be performed together with any one of the technical solutions of the related art.

[0198] As shown in FIG. 10, the measurement method may include, but is not limited to, the following steps 1001 to 1003.

[0199] Step 1001, obtain a measurement value of a target measurement including an RLM measurement and / or an RRM measurement, and the measurement value includes a plurality of second SINRs obtained by measuring each downlink reference signal in a plurality of downlink reference signals a plurality of times within a set time length.

[0200] In the embodiment of the present disclosure, step 1001 can be implemented in any one of the manners in each embodiment of the present disclosure, and the embodiment of the present disclosure is not limited thereto, and detailed description thereof will be omitted.

[0201] In the embodiments of the present disclosure, for the description of the set time length, please refer to any one of the embodiments of the present disclosure, and detailed description will be omitted here.

[0202] In an embodiment of the present disclosure, the terminal device may perform multiple measurements on each downlink reference signal among the multiple downlink reference signals within a set time length to obtain multiple measurement values ​​corresponding to each downlink reference signal, which are referred to as multiple second SINRs in the present disclosure.

[0203] Step 1002, a first quality threshold is determined based on threshold indication information in the reference information corresponding to the target measurement.

[0204] In the embodiment of the present disclosure, step 1002 can be implemented in any one of the manners in each embodiment of the present disclosure, and the embodiment of the present disclosure is not limited thereto, and detailed description thereof will be omitted.

[0205] Step 1003: in response to a plurality of second SINRs corresponding to each downlink reference signal being all greater than a first quality threshold, determining that the target event triggered by the terminal device is an entry into a mitigation event, or in response to the existence of a plurality of second SINRs corresponding to at least one downlink reference signal all greater than the first quality threshold, determining that the target event is an entry into a mitigation event.

[0206] In an embodiment of the present disclosure, when a plurality of second SINRs corresponding to each downlink reference signal are all greater than a first quality threshold, it can be determined that the target event triggered by the terminal device is entering a mitigation event; or when there are a plurality of second SINRs corresponding to at least one downlink reference signal all greater than the first quality threshold, it can be determined that the target event triggered by the terminal device is entering a mitigation event, i.e., it is determined that the terminal device meets the mitigation entry criterion.

[0207] Furthermore, if the second SINR is higher than the first quality threshold, it may be determined that the signal quality of the downlink reference signal is good, and at this time, the entry into the mitigation event may be referred to as a cell signal quality good event.

[0208] The measurement method of the embodiment of the present disclosure obtains a measurement value of a target measurement, where the target measurement includes an RLM measurement and / or an RRM measurement, and determines a target event state triggered by a terminal device based on the measurement value and reference information corresponding to the target measurement, where the target event includes entering a mitigation event or exiting from the mitigation event. This can realize the terminal device to effectively determine whether the terminal device triggers entering a mitigation event based on the measurement value of the target measurement and the reference information corresponding to the target measurement, so that when the terminal device triggers entering a mitigation event, the terminal device can report the entry into the mitigation event to the network device, thereby performing a mitigation mechanism to improve the battery life of the terminal device. In addition, using the reference information corresponding to the target measurement and the measurement value of the target measurement to determine whether the terminal device triggers entering a mitigation event or exiting from the mitigation event can improve the accuracy and reliability of the event determination result.

[0209] It should be noted that these possible implementations described above may be implemented alone or in combination, and the embodiments of the present disclosure are not limited thereto.

[0210] In any one embodiment of the present disclosure, a protocol contract may define an event Event R2 (including an entry into a mitigation event and an exit from a mitigation event).

[0211] As an example, the entry into a mitigation event, such as a cell signal quality good event, may be marked as Event R2-1, and Event R2-1 may be determined based on a signal quality good criterion, that is, when multiple RSs (i.e., reference signals) are configured in a serving cell, each RS may be measured, and the SINR corresponding to the measured RS may be compared with a threshold to determine whether the terminal device meets the signal quality good criterion.

[0212] Furthermore, it may further determine within a set time period T1 whether the terminal device meets a good signal quality criterion.

[0213] In the ninth embodiment, within the set time length T1, all RSs have the same measured SINR measured > First quality threshold (Q out +Offset1), determine that the terminal device meets the good signal quality criterion, and determine that the target event triggered by the terminal device is an entry into a mitigation event or a cell signal quality good event.

[0214] In the tenth embodiment, within the set time length T1, any one of the RSs has a measurement value of SINR measured > First quality threshold (Q out +Offset1), it is determined that the terminal device meets the good signal quality criterion, and the target event triggered by the terminal device is an entry into a mitigation event or a cell signal quality good event.

[0215] Referring to Fig. 11, Fig. 11 is a flowchart of another measurement method provided by an embodiment of the present disclosure. The measurement method may be performed by a terminal device in the communication system shown in Fig. 1. The measurement method may be performed alone, or may be performed in combination with any one of the embodiments of the present disclosure or possible implementation forms in the embodiments, or may be performed together with any one of the technical solutions of the related art.

[0216] As shown in FIG. 11, the measurement method may include, but is not limited to, the following steps 1101 to 1103.

[0217] Step 1101, obtain a measurement value of a target measurement including an RLM measurement and / or an RRM measurement, and the measurement value includes a plurality of second SINRs obtained by measuring each downlink reference signal in a plurality of downlink reference signals a plurality of times within a set time length.

[0218] In the embodiment of the present disclosure, step 1101 can be implemented in any one of the manners in each embodiment of the present disclosure, and the embodiment of the present disclosure is not limited thereto, and detailed description thereof will be omitted.

[0219] Step 1102, a second quality threshold is determined based on threshold indication information in the reference information corresponding to the target measurement.

[0220] In the embodiment of the present disclosure, step 1102 can be implemented in any one of the manners in each embodiment of the present disclosure, and the embodiment of the present disclosure is not limited thereto, and detailed description thereof will be omitted.

[0221] Step 1103: in response to there being a plurality of second SINRs corresponding to at least one downlink reference signal, all of which are below the second quality threshold, it can be determined that the target event triggered by the terminal device is an exit from a mitigation event, or in response to the plurality of second SINRs corresponding to each downlink reference signal all being below the second quality threshold, it is determined that the target event is an exit from a mitigation event.

[0222] In the embodiment of the present disclosure, when there are a plurality of second SINRs corresponding to at least one downlink reference signal, all of which are equal to or less than the second quality threshold, it can be determined that the target event triggered by the terminal device is an exit from the mitigation event, or when a plurality of second SINRs corresponding to each downlink reference signal are equal to or less than the second quality threshold, it can be determined that the target event triggered by the terminal device is an exit from the mitigation event, that is, it can be determined that the terminal device meets the exit from the mitigation criterion.

[0223] Furthermore, if the second SINR is less than or equal to the second quality threshold, it may be determined that the signal quality of the reference signal is poor, and in this case, the exit from the mitigation event may be referred to as a non-cell signal quality good event or a cell signal quality poor event.

[0224] The measurement method of the embodiment of the present disclosure obtains a measurement value of a target measurement, where the target measurement includes an RLM measurement and / or an RRM measurement, and determines a target event state triggered by a terminal device based on the measurement value and reference information corresponding to the target measurement, where the target event includes entering a mitigation event or exiting from the mitigation event. This can realize the terminal device to effectively determine whether the terminal device triggers entering a mitigation event based on the measurement value of the target measurement and the reference information corresponding to the target measurement, so that when the terminal device triggers entering a mitigation event, the terminal device can report the entry into the mitigation event to the network device, thereby performing a mitigation mechanism to improve the battery life of the terminal device. In addition, using the reference information corresponding to the target measurement and the measurement value of the target measurement to determine whether the terminal device triggers entering a mitigation event or exiting from the mitigation event can improve the accuracy and reliability of the event determination result.

[0225] It should be noted that these possible implementations described above may be implemented alone or in combination, and the embodiments of the present disclosure are not limited thereto.

[0226] In any one embodiment of the present disclosure, a protocol contract may define an event Event R2 (including an entry into a mitigation event and an exit from a mitigation event).

[0227] As an example, an exit from a mitigation event, such as a non-cell signal quality good event or a cell signal quality bad event, can be marked as Event R2-2, and Event R2-2 can be determined based on a signal quality good criterion, that is, when multiple RSs (i.e., reference signals) are configured in a serving cell, each RS may be measured, and the SINR corresponding to the measured RS is compared with a threshold to determine whether the terminal device meets the signal quality good criterion.

[0228] Furthermore, it can be determined within a set time period T1 whether the terminal device meets the good signal quality criterion.

[0229] In the embodiment 11, within a set time length T1, an arbitrary RS has a measured value of SINR measured <Second quality threshold (Q out +Offset2), determine that the terminal device does not meet the good signal quality criterion, and determine that the target event triggered by the terminal device is an exit from a mitigation event or a non-cell good signal quality event or a cell bad signal quality event.

[0230] In the 12th embodiment, within the set time length T1, all RSs have a measurement value SINR measured <Second quality threshold (Q out +Offset2), determine that the terminal device does not meet the good signal quality criterion and the target event triggered by the terminal device is an exit from a mitigation event or a non-cell good signal quality event or a cell bad signal quality event.

[0231] In addition, in the above embodiments, the low mobility criterion and the good signal quality criterion are set as an example, and in actual application, the low mobility criterion and the good signal quality criterion can be set at the same time, for example, Event R1 and Event R2 are set at the same time.

[0232] As an example, if the target event is an entry into a mitigation event, two embodiments need to be satisfied simultaneously, where one embodiment may be an embodiment corresponding to FIG. 4 or FIG. 5, and another embodiment may be an embodiment corresponding to FIG. 8 or FIG. 10.

[0233] In one possible implementation, the reference information may include a target period, a first difference threshold, and threshold indication information.

[0234] As an example, the measurement value may include at least one first RSRP obtained by performing at least one measurement on a downlink reference signal within a target time period, or at least one first RSRP obtained by measuring at least one downlink reference signal within a target time period, and the measurement value may further include a plurality of first SINRs obtained by measuring a plurality of downlink reference signals.

[0235] A first difference between the at least one first RSRP and a corresponding reference value can be determined, and in response to the first difference corresponding to the at least one first RSRP being smaller than a first difference threshold in the reference information, it is determined that the terminal device satisfies the low mobility criterion.

[0236] If the terminal device satisfies the low mobility criterion, the terminal device may further determine whether the terminal device satisfies the good cell signal quality criterion, for example, determining that the terminal device satisfies the good cell signal quality criterion in response to all of the multiple first SINRs being greater than a first quality threshold (wherein the first quality threshold is determined based on the threshold indication information), or determining that the terminal device satisfies the good cell signal quality criterion in response to there being at least one first SINR greater than the first quality threshold.

[0237] If the terminal device simultaneously meets the low mobility criterion and the good cell signal quality criterion, it determines that the target event is an entry into a mitigation event.

[0238] As another example, the measurements may include at least one first RSRP obtained by performing at least one measurement on a downlink reference signal within a target time period, or at least one first RSRP obtained by measuring at least one downlink reference signal within a target time period. The measurements may include a plurality of second SINRs obtained by performing multiple measurements on each downlink reference signal of the plurality of downlink reference signals within the set time length.

[0239] A first difference between the at least one first RSRP and a corresponding reference value can be determined, and in response to the first difference corresponding to the at least one first RSRP being smaller than a first difference threshold in the reference information, it is determined that the terminal device satisfies the low mobility criterion.

[0240] If the terminal device satisfies the low mobility criterion, the terminal device may further determine whether the terminal device satisfies the good cell signal quality criterion, for example, determining that the terminal device satisfies the good cell signal quality criterion in response to a plurality of second SINRs corresponding to each downlink reference signal being all greater than a first quality threshold (wherein the first quality threshold is determined based on the threshold indication information), or determining that the terminal device satisfies the good cell signal quality criterion in response to there being a plurality of second SINRs corresponding to at least one downlink reference signal all greater than the first quality threshold.

[0241] If the terminal device simultaneously meets the low mobility criterion and the good cell signal quality criterion, it determines that the target event is an entry into a mitigation event.

[0242] As another example, the measurements are taken over a target period (T SearchDeltaP ) or at least one first RSRP obtained by measuring a downlink reference signal at least once within a target period (T SearchDeltaP ) after the target period. The measurement value further includes a plurality of second RSRPs obtained by measuring the downlink reference signal a plurality of times within a set time length (T1) after the target period, or a plurality of second RSRPs obtained by measuring a plurality of downlink reference signals within the set time length (T1). The measurement value further includes a plurality of first SINRs obtained by measuring a plurality of downlink reference signals.

[0243] A first difference between the at least one first RSRP and a corresponding reference value may be determined, and in response to the first difference corresponding to the at least one first RSRP being smaller than a first difference threshold in the reference information, a second difference between the plurality of second RSRPs and the corresponding reference value is determined, and in response to the second difference corresponding to the plurality of second RSRPs being smaller than the first difference threshold, it is determined that the terminal device satisfies the low mobility criterion.

[0244] If the terminal device satisfies the low mobility criterion, the terminal device may further determine whether the terminal device satisfies the good cell signal quality criterion, for example, determining that the terminal device satisfies the good cell signal quality criterion in response to all of the multiple first SINRs being greater than a first quality threshold value (wherein the first quality threshold is determined based on the threshold indication information), or determining that the terminal device satisfies the good cell signal quality criterion in response to there being at least one first SINR greater than the first quality threshold.

[0245] If the terminal device simultaneously meets the low mobility criterion and the good cell signal quality criterion, it determines that the target event is an entry into a mitigation event.

[0246] As a further example, the measurements may be taken over a target period (T SearchDeltaP ) or at least one first RSRP obtained by measuring a downlink reference signal at least once within a target period (T SearchDeltaP ), the measurement value further includes at least one first RSRP obtained by measuring at least one downlink reference signal within a set time length (T1) after the target period, or the measurement value further includes a plurality of second RSRPs obtained by measuring a plurality of downlink reference signals within the set time length (T1), and the measurement value further includes a plurality of second SINRs obtained by measuring each downlink reference signal of the plurality of downlink reference signals multiple times within the set time length.

[0247] A first difference between the at least one first RSRP and a corresponding reference value may be determined, and in response to the first difference corresponding to the at least one first RSRP being smaller than a first difference threshold in the reference information, a second difference between the plurality of second RSRPs and the corresponding reference value is determined, and in response to the second difference corresponding to the plurality of second RSRPs being smaller than the first difference threshold, it is determined that the terminal device satisfies the low mobility criterion.

[0248] If the terminal device satisfies the low mobility criterion, the terminal device may further determine whether the terminal device satisfies the good cell signal quality criterion, for example, determining that the terminal device satisfies the good cell signal quality criterion in response to a plurality of second SINRs corresponding to each downlink reference signal being all greater than a first quality threshold, or determining that the terminal device satisfies the good cell signal quality criterion in response to there being a plurality of second SINRs corresponding to at least one downlink reference signal all greater than the first quality threshold.

[0249] If the terminal device simultaneously meets the low mobility criterion and the good cell signal quality criterion, it determines that the target event is an entry into a mitigation event.

[0250] For example, if Event R1-1 (Example 1 or Example 2) and Event R2-1 (Example 5, Example 6, Example 9 or Example 10) are simultaneously met, determine that the target event triggered by the terminal device is an entry into a mitigation event, which may be a good cell signal quality event and a low mobility event, and mark it as, for example, Event R3-1.

[0251] As another example, if the target event is an exit from a mitigating event, two embodiments may be satisfied simultaneously, or any one of the two embodiments may be satisfied, where one embodiment may be an embodiment corresponding to Figure 6 or Figure 7, and the other embodiment may be an embodiment corresponding to Figure 9 or Figure 11.

[0252] In one possible implementation, the reference information may include a target period, a second difference threshold, and a threshold indication information.

[0253] In one example, the measurements include at least one first RSRP obtained by performing at least one measurement on a downlink reference signal within the target time period, or at least one first RSRP obtained by measuring at least one downlink reference signal within the target time period, and further include a plurality of first SINRs obtained by measuring a plurality of downlink reference signals.

[0254] A first difference between the at least one first RSRP and a corresponding reference value may be determined, and in response to there being at least one first difference corresponding to the first RSRP that is greater than or equal to a second difference threshold in the reference information, it is determined that the terminal device does not satisfy the low mobility criterion.

[0255] Further, a second quality threshold is determined based on the threshold indication information, and in response to the existence of at least one first SINR that is equal to or less than the second quality threshold, it is determined that the terminal device does not satisfy the cell signal quality good criterion, or in response to all of the multiple first SINRs being equal to or less than the second quality threshold, it is determined that the terminal device does not satisfy the cell signal quality good criterion.

[0256] If the terminal device does not meet the low mobility criterion and / or if the terminal device does not meet the good cell signal quality criterion, it is determined that the target event is an exit from a mitigation event.

[0257] As another example, the measurements include at least one first RSRP obtained by performing at least one measurement on a downlink reference signal within a target time period, or at least one first RSRP obtained by measuring at least one downlink reference signal within a target time period, and further include a plurality of second SINRs obtained by measuring each downlink reference signal of the plurality of downlink reference signals a plurality of times within the set time length.

[0258] A first difference between the at least one first RSRP and a corresponding reference value may be determined, and in response to there being at least one first difference corresponding to the first RSRP that is greater than or equal to a second difference threshold in the reference information, it is determined that the terminal device does not satisfy the low mobility criterion.

[0259] Further, a second quality threshold may be determined based on the threshold indication information, and in response to the existence of a plurality of second SINRs corresponding to at least one downlink reference signal, all of which are equal to or less than the second quality threshold, the terminal device is determined to not satisfy the good cell signal quality criterion, or in response to the plurality of second SINRs corresponding to each downlink reference signal being all smaller than the second quality threshold, the terminal device is determined to not satisfy the good cell signal quality criterion.

[0260] If the terminal device does not meet the low mobility criterion and / or if the terminal device does not meet the good cell signal quality criterion, it is determined that the target event is an exit from a mitigation event.

[0261] As another example, the measurements include at least one first RSRP obtained by performing at least one measurement on a downlink reference signal within a target period, or at least one first RSRP obtained by measuring at least one downlink reference signal within the target period. The measurements also include a plurality of second RSRPs obtained by measuring the downlink reference signal a plurality of times within a set time length after the target period, or a plurality of second RSRPs obtained by measuring a plurality of downlink reference signals within the set time length. The measurements also include a plurality of first SINRs obtained by measuring a plurality of downlink reference signals.

[0262] A first difference between the at least one first RSRP and a corresponding reference value may be determined, and in response to the presence of at least one first difference corresponding to the first RSRP being equal to or greater than the second difference threshold, a second difference between the plurality of second RSRPs and the corresponding reference value is determined, and in response to the presence of at least one second difference corresponding to the second RSRP being equal to or greater than the second difference threshold, it is determined that the terminal device does not satisfy the low mobility criterion.

[0263] Further, a second quality threshold may be determined based on the threshold indication information, and in response to the existence of at least one first SINR that is equal to or less than the second quality threshold, it is determined that the terminal device does not satisfy the cell signal quality good criterion, or in response to all of the multiple first SINRs being equal to or less than the second quality threshold, it is determined that the terminal device does not satisfy the cell signal quality good criterion.

[0264] If the terminal device does not meet the low mobility criterion and / or if the terminal device does not meet the good cell signal quality criterion, it is determined that the target event is an exit from a mitigation event.

[0265] As a further example, the measurements include at least one first RSRP obtained by performing at least one measurement on a downlink reference signal within the target time period, or at least one first RSRP obtained by measuring at least one downlink reference signal within the target time period, and further include a plurality of second RSRPs obtained by measuring the downlink reference signal a plurality of times within a set time length after the target time period, or further include a plurality of second RSRPs obtained by measuring a plurality of downlink reference signals within the set time length, and further include a plurality of second SINRs obtained by measuring each downlink reference signal of the plurality of downlink reference signals a plurality of times within the set time length.

[0266] A first difference between the at least one first RSRP and a corresponding reference value may be determined, and in response to the presence of at least one first difference corresponding to the first RSRP being equal to or greater than the second difference threshold, a second difference between the plurality of second RSRPs and the corresponding reference value is determined, and in response to the presence of at least one second difference corresponding to the second RSRP being equal to or greater than the second difference threshold, it is determined that the terminal device does not satisfy the low mobility criterion.

[0267] Further, a second quality threshold may be determined based on the threshold indication information, and in response to the existence of a plurality of second SINRs corresponding to at least one downlink reference signal, all of which are equal to or less than the second quality threshold, the terminal device is determined to not satisfy the good cell signal quality criterion, or in response to the plurality of second SINRs corresponding to each downlink reference signal being all smaller than the second quality threshold, the terminal device is determined to not satisfy the good cell signal quality criterion.

[0268] If the terminal device does not meet the low mobility criterion and / or if the terminal device does not meet the good cell signal quality criterion, it is determined that the target event is an exit from a mitigation event.

[0269] For example, when one of Event R1-2 (Example 3 or Example 4) or Event R2-2 (Example 7, Example 8, Example 11 or Example 12) is met, it can be determined that the target event triggered by the terminal device is an exit from a mitigation event, which may be a non-cell signal quality good event (cell signal quality poor event) and / or a non-low mobility event (high / low mobility event), for example, described as Event R3-2.

[0270] In any one embodiment of the present disclosure, the network device may configure reference information corresponding to the low mobility reference through an RRC message.

[0271] As an example, the reference information for the low mobility reference is a target period TSearchDeltaP , the first difference threshold S SearchDeltaP and / or a second difference threshold SSearchDeltaP'.

[0272] For the low mobility criterion, the measurement obtained by the terminal device may be L3-RSRP.

[0273] As an example, the criterion information for the cell signal quality good criterion may include threshold indication information (eg, Offset1 and / or Offset2).

[0274] For the cell signal quality good criterion, the measurement value obtained by the terminal device may be L1-SINR.

[0275] In any one embodiment of the present disclosure, the network device may configure at least one event for RLM measurements and / or RRM measurement mitigation.

[0276] As an example, the network device may configure Event R1 for RRM measurement mitigation, i.e., perform the RRM mitigation mechanism when the mitigation entry criteria corresponding to Event R1 are met. The network device may configure Event R2 for RLM measurement mitigation, i.e., perform the RLM mitigation mechanism when the mitigation entry criteria corresponding to Event R2 are met. The network device may configure Event R1+Event R2 for RLM measurement mitigation, e.g., perform the RRM mitigation mechanism when the mitigation entry criteria corresponding to Event R2 and Event R1 are met simultaneously. The network device may configure Event R3 (Event R3-1, Event R3-2) for RLM measurement mitigation or RRM measurement mitigation.

[0277] Referring to Fig. 12, Fig. 12 is a flowchart of another measurement method provided by an embodiment of the present disclosure. The measurement method may be performed by a terminal device in the communication system shown in Fig. 1. The measurement method may be performed alone, or may be performed in combination with any one of the embodiments of the present disclosure or possible implementation forms in the embodiments, or may be performed together with any one of the technical solutions of the related art.

[0278] As shown in FIG. 12, the measurement method may include, but is not limited to, the following steps 1201 to 1204.

[0279] Step 1201, measurements of target measurements including RLM measurements and / or RRM measurements are obtained.

[0280] In step 1202, based on the measurement value and the criteria information corresponding to the target measurement, it can be determined that the target event triggered by the terminal device is an exit from the mitigation event.

[0281] Steps 1201 to 1202 can be implemented by any one of the methods in the embodiments of FIG. 2, FIG. 3, FIG. 6, and FIG. 9 of the present disclosure, but the embodiments of the present disclosure are not limited thereto, and detailed description thereof will be omitted here.

[0282] Step 1203, in response to the target event being an exit from the mitigation event, reads a first possible value of a first timer, where the first timer times based on the time the terminal device last determined that an exit from the mitigation event was triggered.

[0283] In an embodiment of the present disclosure, the first timer times based on the time when the terminal device last determined that an exit from the mitigation event was triggered, i.e., the first timer times based on the time when the terminal device last determined that an exit from the mitigation criteria was satisfied.

[0284] In an embodiment of the present disclosure, if the target event is an exit from a mitigation event, a first possible value of the timer may be read, which is referred to in the present disclosure as the first possible value.

[0285] Step 1204, in response to the first possible value being greater than the first count threshold and the second timer not running, sending an exit from the mitigation event and / or a measurement value to the network device, where the second timer times based on the time the terminal device last sent an exit from the mitigation event.

[0286] In an embodiment of the present disclosure, the second timer is timed based on the time when the terminal device last transmits an exit from the mitigation event, i.e., based on the time when the terminal device triggers the exit from the mitigation event and reports the exit from the mitigation event to the network device, where the second timer is started when the terminal device reports the exit from the mitigation event to the network device, and stops timing after a first set time period has elapsed since the second timer was started.

[0287] In an embodiment of the present disclosure, the first counting threshold is pre-set, for example, the first counting threshold may be set by a network device or may be promised by a protocol, and is not limited by the present disclosure.

[0288] In an embodiment of the present disclosure, in order to prevent the terminal device from frequently reporting information to the network device, the present disclosure may transmit an exit from the mitigation event and / or a measurement value to the network device when the first possible value of the first timer is greater than a first counting threshold (i.e., the first timer times out) and the second timer is not running. That is, when the duration length for which the terminal device triggers an exit from the mitigation event (i.e., the duration length for which the terminal device meets the mitigation exit criteria) reaches the first counting threshold and the terminal device does not report the exit from the mitigation event to the network device within a short short period of time (i.e., a first set time length), the terminal device may report the exit from the mitigation event and / or a measurement value to the network device.

[0289] In addition, when the second timer is operating, it indicates that the terminal device has reported an exit from the mitigation event to the network device within the first set time length, and in order to avoid the terminal device performing and reporting the event frequently, in one possible implementation form of the embodiment of the present disclosure, when the first possible value is greater than the first counting threshold and the second timer is operating, the terminal device does not need to report the target event (i.e., exit from the mitigation event) to the network device because the terminal device has reported an exit from the mitigation event to the network device within a short period of time.

[0290] In one possible implementation of an embodiment of the present disclosure, if the first possible value of the first timer is less than or equal to a first counting threshold (i.e., the first timer has not timed out), the terminal device may not operate or respond, for example, the terminal device may not report a target event (i.e., an exit from a mitigation event) to the network device.

[0291] In any one of the embodiments of the present disclosure, if the target event triggered by the terminal device is an exit from a mitigation event, indicating that the signal quality of the serving cell is not good, and at this time, it is not limited by the second timer, i.e., when the first possible value of the first timer is greater than the first counting threshold, the terminal device can send the exit from the mitigation event and / or the measurement value to the network device.

[0292] The measurement method of the embodiment of the present disclosure obtains a measurement value of a target measurement, where the target measurement includes an RLM measurement and / or an RRM measurement, and determines a target event state triggered by a terminal device based on the measurement value and reference information corresponding to the target measurement, where the target event includes entering a mitigation event or exiting from the mitigation event. This can realize the terminal device to effectively determine whether the terminal device triggers entering a mitigation event based on the measurement value of the target measurement and the reference information corresponding to the target measurement, so that when the terminal device triggers entering a mitigation event, the terminal device can report the entry into the mitigation event to the network device, thereby performing a mitigation mechanism to improve the battery life of the terminal device. In addition, using the reference information corresponding to the target measurement and the measurement value of the target measurement to determine whether the terminal device triggers entering a mitigation event or exiting from the mitigation event can improve the accuracy and reliability of the event determination result.

[0293] It should be noted that these possible implementations described above may be implemented alone or in combination, and the embodiments of the present disclosure are not limited thereto.

[0294] In addition, the setting of the first timer is to determine whether or not to report an exit from a mitigation event to the network device based on the possible values ​​of the first timer if the set time length is not set.

[0295] However, when a set time length is set, if the target event triggered by the terminal device is an exit from a mitigation event, for example based on the embodiment shown in FIG. 7 or FIG. 11, it can be determined that the target event triggered by the terminal device is an exit from the mitigation event, whereby the terminal device can determine whether the second timer is running or not, and if the target event is an exit from the mitigation event and the second timer is not running, the terminal device can send the exit from the mitigation event and / or a measurement value to the network device, and if the target event is an exit from the mitigation event and the second timer is running, the terminal device may not send the exit from the mitigation event to the network device, for example, the terminal device may send only the measurement value to the network device.

[0296] Alternatively, if a set time length is set, it may not be limited by the second timer, i.e. if the target event triggered by the terminal device is an exit from a mitigation event, the terminal device may transmit the exit from the mitigation event and / or measurements to the network device.

[0297] Referring to Fig. 13, Fig. 13 is a flowchart of another measurement method provided by an embodiment of the present disclosure. The measurement method may be performed by a terminal device in the communication system shown in Fig. 1. The measurement method may be performed alone, or may be performed in combination with any one of the embodiments of the present disclosure or possible implementation forms in the embodiments, or may be performed together with any one of the technical solutions of the related art.

[0298] As shown in FIG. 13, the measurement method may include, but is not limited to, the following steps 1301 to 1304.

[0299] Step 1301, obtain measurements of target measurements including RLM measurements and / or RRM measurements.

[0300] Step 1302, based on the measurement value and the reference information corresponding to the target measurement, determines that the target event triggered by the terminal device is an entry into a mitigation event.

[0301] Steps 1301 to 1302 can be implemented by any one of the embodiments of FIG. 2, FIG. 3, FIG. 4, and FIG. 8 of the present disclosure, but the embodiments of the present disclosure are not limited thereto, and detailed description thereof will be omitted here.

[0302] Step 1303, in response to the target event being an entry into a mitigation event, reads a first possible value of a third timer, where the third timer times based on the time the terminal device most recently determined that an entry into the mitigation event was triggered.

[0303] In an embodiment of the present disclosure, the third timer times based on the time when the terminal device last determined that entry into a mitigation event was triggered, i.e., the third timer times based on the time when the terminal device last determined that the mitigation entry criteria were met.

[0304] In an embodiment of the present disclosure, when the target event triggered by the terminal device is an entry into a mitigation event, the possible value of the third timer may be read, which is described as the second possible value in the present disclosure.

[0305] Step 1304, in response to the second possible value being greater than the second count threshold and the fourth timer not running, transmitting the mitigation event entry and / or measurement value to the network device, where the fourth timer is timed based on the time the terminal device last transmitted the mitigation event entry.

[0306] In an embodiment of the present disclosure, the fourth timer is timed based on the time when the terminal device last sends an entry into a mitigation event, i.e., the fourth timer is timed based on the time when the terminal device most recently triggers an entry into a mitigation event and reports the entry into the mitigation event to the network device, where the fourth timer is started when the terminal device reports the entry into the mitigation event to the network device, and stops timing after a second set time period has elapsed since the fourth timer was started.

[0307] In an embodiment of the present disclosure, the second counting threshold is pre-set, for example, the second counting threshold may be set by a network device or may be promised by a protocol, and is not limited by the present disclosure.

[0308] In an embodiment of the present disclosure, in order to avoid the terminal device from frequently reporting information to the network device, the present disclosure may report the entry into the mitigation state and / or the measurement value to the network device when the second possible value of the third timer is greater than the second counting threshold (i.e., the third timer is in a timeout) and the fourth timer is not running. That is, when the duration length for which the terminal device triggers the entry into the mitigation event (i.e., the duration length for which the terminal device meets the mitigation entry criteria) reaches the second counting threshold and the terminal device has not reported the entry into the mitigation event to the network device within a short period (i.e., a second set time length), the entry into the mitigation state and / or the measurement value may be reported to the network device.

[0309] In addition, when the fourth timer is operating, this indicates that the terminal device has reported entry into a mitigation event to the network device within the second set time period. In order to avoid the terminal device from frequently calculating and reporting events, in one possible implementation form of an embodiment of the present disclosure, when the second possible value is greater than the second counting threshold and the fourth timer is operating, the terminal device does not need to report the target event (i.e., entry into a mitigation event) to the network device, because the terminal device has reported entry into a mitigation event to the network device within a short period of time.

[0310] In one possible implementation of the disclosed embodiment, if the second possible value of the third timer is less than or equal to the second count threshold (i.e., the third timer has not timed out), the terminal device may not operate or respond, e.g., the terminal device may not report the target event (i.e., entering a mitigation event) to the network device.

[0311] The measurement method of the embodiment of the present disclosure obtains a measurement value of a target measurement, where the target measurement includes an RLM measurement and / or an RRM measurement, and determines a target event state triggered by a terminal device based on the measurement value and reference information corresponding to the target measurement, where the target event includes entering a mitigation event or exiting from the mitigation event. This can realize the terminal device to effectively determine whether the terminal device triggers entering a mitigation event based on the measurement value of the target measurement and the reference information corresponding to the target measurement, so that when the terminal device triggers entering a mitigation event, the terminal device can report the entry into the mitigation event to the network device, thereby performing a mitigation mechanism to improve the battery life of the terminal device. In addition, using the reference information corresponding to the target measurement and the measurement value of the target measurement to determine whether the terminal device triggers entering a mitigation event or exiting from the mitigation event can improve the accuracy and reliability of the event determination result.

[0312] It should be noted that these possible implementations described above may be implemented alone or in combination, and the embodiments of the present disclosure are not limited thereto.

[0313] In addition, the setting of the third timer is to determine whether or not to report the entry into a mitigation event to the network device based on the possible values ​​of the third timer if the set time length is not set.

[0314] However, when a set time length is set, if the target event triggered by the terminal device is an entry into a mitigation event, for example, based on the embodiment shown in FIG. 5 or FIG. 10, it is determined that the target event triggered by the terminal device is an entry into a mitigation event, so that the terminal device can determine whether the fourth timer is running or not, and if the target event is an entry into a mitigation event and the fourth timer is not running, the terminal device can send the entry into the mitigation event and / or the measurement value to the network device, and if the target event is an entry into a mitigation event and the fourth timer is running, the terminal device may not send the entry into the mitigation event to the network device, for example, the terminal device may only send the measurement value to the network device.

[0315] Alternatively, if a set time length is set, it may be limited by a fourth timer, i.e. if the target event triggered by the terminal device is an entry into a mitigation event, the terminal device may transmit the entry into the mitigation event and / or the measurement value to the network device.

[0316] Referring to Fig. 14, Fig. 14 is a flowchart of another measurement method provided by an embodiment of the present disclosure. The measurement method may be performed by a terminal device in the communication system shown in Fig. 1. The measurement method may be performed alone, or may be performed in combination with any one of the embodiments of the present disclosure or possible implementation forms in the embodiments, or may be performed together with any one of the technical solutions of the related art.

[0317] As shown in FIG. 14, the measurement method may include, but is not limited to, the following steps 1401 to 1403.

[0318] Step 1401, obtain measurements of target measurements including RLM measurements and / or RRM measurements.

[0319] Step 1402: Determine a target event triggered by the terminal device based on the measurement value and reference information corresponding to the target measurement, where the target event includes entering or exiting a mitigation event.

[0320] Each of steps 1401 to 1402 can be realized by any one of the methods of the embodiments of the present disclosure, but the embodiments of the present disclosure are not limited thereto, and detailed description thereof will be omitted.

[0321] Step 1403, in response to the target event being an exit from a mitigation event, sending an exit from the mitigation event and / or a measurement value to the network device, or in response to the target event being an entry into a mitigation event, sending an entry into the mitigation event and / or a measurement value to the network device.

[0322] In the embodiment of the present disclosure, it is possible to determine whether to report the target event and / or the measurement value to the network device, regardless of the possible value of the timer. For example, when the terminal device triggers the target event, the terminal device may automatically report the target event and / or the measurement value to the network device. That is, if the target event is an exit from a mitigation event, the terminal device may send the exit from the mitigation event and / or the measurement value to the network device, and if the target event is an entry into a mitigation event, the terminal device may send the entry into the mitigation event and / or the measurement value to the network device.

[0323] The measurement method of the embodiment of the present disclosure obtains a measurement value of a target measurement, where the target measurement includes an RLM measurement and / or an RRM measurement, and determines a target event state triggered by a terminal device based on the measurement value and reference information corresponding to the target measurement, where the target event includes entering a mitigation event or exiting from the mitigation event. This can realize the terminal device to effectively determine whether the terminal device triggers entering a mitigation event based on the measurement value of the target measurement and the reference information corresponding to the target measurement, so that when the terminal device triggers entering a mitigation event, the terminal device can report the entry into the mitigation event to the network device, thereby performing a mitigation mechanism to improve the battery life of the terminal device. In addition, using the reference information corresponding to the target measurement and the measurement value of the target measurement to determine whether the terminal device triggers entering a mitigation event or exiting from the mitigation event can improve the accuracy and reliability of the event determination result.

[0324] It should be noted that these possible implementations described above may be implemented alone or in combination, and the embodiments of the present disclosure are not limited thereto.

[0325] Referring to Figure 15, Figure 15 is a flowchart of another measurement method provided by an embodiment of the present disclosure. The measurement method may be performed by a terminal device in the communication system shown in Figure 1. The measurement method may be performed alone, or may be performed in combination with any one of the embodiments of the present disclosure or possible implementation forms in the embodiments, or may be performed together with any one of the technical solutions of the related art.

[0326] As shown in FIG. 15, the measurement method may include, but is not limited to, the following steps 1501 to 1504.

[0327] Step 1501, obtain measurements of target measurements including RLM measurements and / or RRM measurements.

[0328] Step 1502, determine a target event to be triggered by the terminal device based on the measurement value and reference information corresponding to the target measurement.

[0329] Each of steps 1501 to 1502 can be realized by any one of the methods of the embodiments of the present disclosure, but the embodiments of the present disclosure are not limited thereto, and detailed description thereof will be omitted.

[0330] Step 1503, in response to the target event being an entry into a mitigation event, determines a first measurement interval during which the terminal device periodically performs target measurements in the mitigation state.

[0331] In an embodiment of the present disclosure, when a target event triggered by a terminal device is an entry into a mitigation event, a first measurement interval for periodically performing target measurements in a mitigation state, preferred by the terminal device, can be determined.

[0332] For example, when the terminal device is not in a relaxed state, the terminal device may periodically perform target measurements using a small measurement interval, for example, performing one measurement every 5 seconds, and when the terminal device enters a relaxed state, the terminal device may periodically perform target measurements using a large measurement interval, for example, performing one measurement every 10 seconds, i.e., the first measurement interval may be 10 seconds.

[0333] Step 1504: Send interval indication information corresponding to the first measurement interval to the network device, where the interval indication information includes a proportionality coefficient between the first measurement interval and a second measurement interval set by the network device.

[0334] In an embodiment of the present disclosure, the terminal device may send interval indication information corresponding to a first measurement interval to the network device, where the interval indication information may include a proportional coefficient between the first measurement interval and a second measurement interval set by the network device, so that after the network device receives the interval indication information, it can set the measurement interval corresponding to the terminal device according to the proportional coefficient in the interval indication information, for example, set the measurement interval of the terminal device to the first measurement interval.

[0335] Still taking the above example as an example, the first measurement interval preferred by the terminal device is 10 seconds, and the second measurement interval set by the network device is 5 seconds, so the proportionality coefficient is 2, and the network device can adjust the second measurement interval to 10 seconds according to the proportionality coefficient.

[0336] The measurement method of the embodiment of the present disclosure obtains a measurement value of a target measurement, where the target measurement includes an RLM measurement and / or an RRM measurement, and determines a target event state triggered by a terminal device based on the measurement value and reference information corresponding to the target measurement, where the target event includes entering a mitigation event or exiting from the mitigation event. This can realize the terminal device to effectively determine whether the terminal device triggers entering a mitigation event based on the measurement value of the target measurement and the reference information corresponding to the target measurement, so that when the terminal device triggers entering a mitigation event, the terminal device can report the entry into the mitigation event to the network device, thereby performing a mitigation mechanism to improve the battery life of the terminal device. In addition, using the reference information corresponding to the target measurement and the measurement value of the target measurement to determine whether the terminal device triggers entering a mitigation event or exiting from the mitigation event can improve the accuracy and reliability of the event determination result.

[0337] It should be noted that these possible implementations described above may be implemented alone or in combination, and the embodiments of the present disclosure are not limited thereto.

[0338] Referring to Figure 16, Figure 16 is a flowchart of another measurement method provided by an embodiment of the present disclosure. The measurement method may be performed by a terminal device in the communication system shown in Figure 1. The measurement method may be performed alone, or may be performed in combination with any one of the embodiments of the present disclosure or possible implementation forms in the embodiments, or may be performed together with any one of the technical solutions of the related art.

[0339] As shown in FIG. 16, the measurement method may include, but is not limited to, the following steps 1601 to 1605.

[0340] Step 1601, obtain measurements of target measurements including RLM measurements and / or RRM measurements.

[0341] Step 1602, based on the measurement value and the reference information corresponding to the target measurement, determines that the target event triggered by the terminal device is an entry into a mitigation event.

[0342] Step 1603 transmits the mitigation event entry and / or measurement to a network device.

[0343] Each of steps 1601 to 1603 can be realized by any one of the methods of the embodiments of the present disclosure, but the embodiments of the present disclosure are not limited thereto, and detailed description thereof will be omitted.

[0344] Step 1604 receives a mitigation command sent from a network device.

[0345] In an embodiment of the present disclosure, after receiving an entry into a mitigation event transmitted from a terminal device, the network device may send a mitigation command to the terminal device, which controls the terminal device to enter a mitigation state.

[0346] Step 1605: In response to the mitigation command, control the terminal device to enter a mitigation state.

[0347] In an embodiment of the present disclosure, after receiving a mitigation command sent from a network device, the terminal device can enter a mitigation state in response to the mitigation command.

[0348] In one possible implementation form of the embodiment of the present disclosure, the mitigation command may further include a target proportionality coefficient, where the target proportionality coefficient may be generated by the network device based on a proportionality coefficient in the interval indication information sent from the terminal device, or the target proportionality coefficient may be automatically generated by the network device, and the present disclosure is not limited thereto. After the terminal device enters the mitigation state, it can determine a target measurement interval based on the target proportionality coefficient in the mitigation command and the second measurement interval set by the network device, for example, the product of the target proportionality coefficient and the second measurement interval can be the target measurement interval, so that the terminal device can periodically perform target measurement based on the target measurement interval in the mitigation state.

[0349] The measurement method of the embodiment of the present disclosure obtains a measurement value of a target measurement, where the target measurement includes an RLM measurement and / or an RRM measurement, and determines a target event state triggered by a terminal device based on the measurement value and reference information corresponding to the target measurement, where the target event includes entering a mitigation event or exiting from the mitigation event. This can realize the terminal device to effectively determine whether the terminal device triggers entering a mitigation event based on the measurement value of the target measurement and the reference information corresponding to the target measurement, so that when the terminal device triggers entering a mitigation event, the terminal device can report the entry into the mitigation event to the network device, thereby performing a mitigation mechanism to improve the battery life of the terminal device. In addition, using the reference information corresponding to the target measurement and the measurement value of the target measurement to determine whether the terminal device triggers entering a mitigation event or exiting from the mitigation event can improve the accuracy and reliability of the event determination result.

[0350] It should be noted that these possible implementations described above may be implemented alone or in combination, and the embodiments of the present disclosure are not limited thereto.

[0351] In any one of the embodiments of the present disclosure, the terminal device can report a target event to a network device through terminal assistance information UE Assistance Information (UAI for short).

[0352] As an example, the network device can configure, via an RRC message (e.g., RRC Reconfiguration=>otherConfig), whether the terminal device needs to perform mitigation event detection (i.e., whether it needs to perform target event detection) and can configure related timer values. The network device can also configure whether the terminal device is allowed to report preferred mitigation parameters, which in the present disclosure are referred to as interval indication information corresponding to the first measurement interval.

[0353] For example, the RRC message may include the following information: OtherConfig::= SEQUENCE { … rlm-ReportConfig CHOICE { release NULL, setup SEQUENCE rlmReportTimer ENUMERATED {…}, rlmReportPreferRelax ENUMERATED {setup} } … }

[0354] Here, rlmReportTimer may be the second or fourth timer below to avoid frequent reporting by the UAI, and rlmReportPreferRelax is the parameter reported by the UAI below.

[0355] Here, information such as measurements and target events obtained by the terminal device may be included in an RLM report (rlmReport).

[0356] As an example, the terminal device may specifically perform UAI initialization and report specific content.

[0357] The terminal device can decide whether to report or not based on the triggered target event (entering a mitigation event or exiting a mitigation event), where the reporting type may be per terminal device (per UE) or per serving cell group (per CG).

[0358] Here, when the terminal device reports according to per UE, it determines whether the target event triggered by the terminal device is an entry into a mitigation event or an exit from a mitigation event based on the SINR of a reference signal of a primary serving cell (PCell), and when the terminal device reports according to per CG, it determines whether the target event triggered by the terminal device is an entry into a mitigation event or an exit from a mitigation event based on the SINR of a reference signal of a primary serving cell (PCell) or a primary secondary serving cell (PScell).

[0359] That is, in any one of the embodiments of the present disclosure, when the reporting type of the target event is a terminal device, the measurement value of the primary serving cell and / or the target event corresponding to the terminal device can be sent to the network device, that is, when the reporting type of the target event is a terminal device, the terminal device can measure the downlink reference signal of the primary serving cell, and determine the target event where the terminal device is located based on the measurement value, so that the information reported to the network device is the measurement value of the primary serving cell and / or the target event.

[0360] In any one of the embodiments of the present disclosure, when the reporting type of the target event is a cell group, the measurement value of the primary serving cell in the cell group corresponding to the terminal device and / or the target event may be sent to a network device, or the measurement value of the primary secondary serving cell in the cell group corresponding to the terminal device and / or the target event may be sent to a network device.

[0361] For example, if the cell group is an MCG, the terminal device can measure the downlink reference signal of the primary serving cell in the MCG and determine the target event in which the terminal device is located based on the measurement value, so that the information reported by the network device is the measurement value and / or the target event of the primary serving cell in the MCG corresponding to the terminal device.

[0362] If the cell group is an SCG, the terminal device may measure the downlink reference signal of the primary secondary service cell in the SCG, and based on the measurement value, determine the target event where the terminal device is located, so that the information reported by the network device is the measurement value and / or the target event of the primary secondary service cell in the SCG corresponding to the terminal device.

[0363] Here, when a low mobility criterion or a good cell signal quality criterion is set, the reporting of the UAI message may be reported by one message, i.e., the UAI message reports a good cell signal quality event or a good non-cell signal quality event, or reports a low mobility event or a non-low mobility event.

[0364] When the low mobility criterion and the good cell signal quality criterion are set simultaneously, the report of the UAI message may be divided into two separate messages and reported respectively, where one UAI message is used to report the good cell signal quality event or the good non-cell signal quality event, and the other message is used to report the low mobility event or the non-low mobility event, or the report of the UAI message may be reported by one message, for example, the UAI message is used to report the good cell signal quality event or the good non-cell signal quality event, and the low mobility event or the non-low mobility event.

[0365] 1) UAI initialization may be as follows: When the network device sets the terminal device to report a target event, i.e., when the network device sets the terminal device to report a mitigation event, if the terminal device detects an exit from the mitigation event (the first timer times out) and the second timer is not running, it sets the value of the second timer to the timer value set by the network device, starts the second timer, initializes UAI transmission, and reports the content to the network device according to the following steps: When the terminal device detects an entry into the mitigation event (the third timer times out) and the fourth timer is not running, it sets the value of the fourth timer to the timer value set by the network device, starts the fourth timer, initializes UAI transmission, and reports the information to the network device according to the following steps:

[0366] 2) The contents of the report are as follows: The terminal device can report an RLM report to the network device via UEAssistanceInformation, including, but not limited to, exit from a mitigation event, entry into a mitigation event, mitigation parameters preferred by the terminal device (i.e., interval indication information corresponding to the first measurement interval), measurement values, etc.

[0367] For example, when the terminal device is configured to provide RLM reporting, when the first timer times out, it automatically triggers a report by the terminal device, and the reported target event is an exit from a mitigation event, i.e., it reports that the target state in which the terminal device is located is an exit mitigation state. When the third timer times out, it automatically triggers a report by the terminal device, and the reported target event is an entry into a mitigation event. That is, when reporting by a UAI message, the exit from a mitigation event may not be restricted by the second or fourth timers.

[0368] If the terminal device is configured to report measurement results, the terminal device may report the measurements to the network device.

[0369] If the terminal device is configured to report a preferred relaxation parameter (PreferRelax), the terminal device may report interval indication information corresponding to the first measurement interval to the network device.

[0370] Here, the definitions of the relevant timers may be as shown in Table 1.

[0371] [Table 1]

[0372] Note that each element and corresponding relationship in Table 1 exists independently, and although these elements and corresponding relationships are shown in one table as an example, not all elements and corresponding relationships in the table necessarily exist simultaneously as shown in 1. The value of each element and each corresponding relationship is independent of the value or corresponding relationship of any other element in Table 1. Therefore, it is easy for a person skilled in the art to understand that each possible value of each element and each corresponding relationship in Table 1 are independent embodiments.

[0373] In Table 1, if the low mobility criterion is set in the UAI, the terminal device reports a low mobility event or a non-low mobility event to the network device under the restriction of the Prohibit timer.

[0374] If the UAI is set to a good cell signal quality criterion, the terminal device reports a good cell signal quality event or a good non-cell signal quality event to the network device under the restriction of the Prohibit timer.

[0375] If a low mobility criterion and a good cell signal quality criterion are set in the UAI, the terminal device reports a good cell signal quality event and a low mobility event to the network device under the restriction of the Prohibit timer, and reports an exit from the mitigation event if any one of the criteria is not met.

[0376] In any one of the embodiments of the present disclosure, the terminal device may report the target event and / or the measurement value through an RRC message, where the report type may be per UE / CG.

[0377] As an example, the network device may signal a measurement configuration measConfig to the terminal device via an RRC message such as an RRCReconfiguration message, where the measurement configuration may be bound to a measurement object (measObject), a report configuration (reportConfig) and a configuration ID (measId).

[0378] The measurement target of the measurement configuration may be a serving cell of the terminal device; The reporting of the measurement configuration may be triggered based on an event.

[0379] When the terminal device receives the measurement configuration, it may execute a corresponding measurement process, for example, automatically trigger a report when the measurement value meets a condition corresponding to the event, and the report information may include the measurement value and / or the entry condition of the event is met, i.e., the target event is entering the mitigation event; automatically trigger a report when the measurement value meets an exit condition corresponding to the event, and the report information may include the measurement value and / or the exit condition is met, i.e., the target event is exiting from the mitigation event.

[0380] 17, which is a flowchart of another measurement method provided by an embodiment of the present disclosure, which may be performed by a network device in the communication system shown in FIG.

[0381] As shown in FIG. 17, the measurement method may include, but is not limited to, the following step 1701.

[0382] Step 1701: receiving a target event and / or a measurement value transmitted from a terminal device, where the measurement value is a measurement value of a target measurement, the target measurement includes a radio link monitor (RLM) measurement and / or a radio resource management (RRM) measurement, the target event is determined based on the measurement value and reference information corresponding to the target measurement, and the target event includes entering or exiting a mitigation event.

[0383] In one possible implementation of the embodiments of the present disclosure, the network device can further send reference information to the terminal device.

[0384] In one possible implementation of an embodiment of the present disclosure, the network device can send a mitigation command to the terminal device in response to the target event being an entry into a mitigation event, where the mitigation command can control the terminal device to enter a mitigation state.

[0385] In addition, the description of the measurement method performed by a terminal device in any one of the above embodiments also applies to the measurement method performed by the network device, and the implementation principle is similar, so detailed description is omitted here.

This can realize the terminal device to effectively determine whether the terminal device triggers entering a mitigation event based on the measurement value of the target measurement and the reference information corresponding to the target measurement, so that when the terminal device triggers entering a mitigation event, the terminal device can report the entry into the mitigation event to the network device, thereby performing a mitigation mechanism to improve the battery life of the terminal device. In addition, using the reference information corresponding to the target measurement and the measurement value of the target measurement to determine whether the terminal device triggers entering a mitigation event or exiting the mitigation event can improve the accuracy and reliability of the event determination result.
