S210, the network device sends first indication information to the terminal device.

Specifically, the first indication information is used to indicate the first reference signal type. Further, the first indication information is used to instruct the terminal device to perform a first determination on the reference signal of the first reference signal type, and the first determination is used to determine the difference between the measured value of the reference signal of the first reference signal type and the first threshold Whether the relationship satisfies the first criterion. Optionally, the first indication information is also used to indicate the first threshold, or offset information. It should be noted that if the first indication information is used to indicate offset information, it is possible that the terminal device has received the threshold information once in the idle state or inactive state, and the terminal device combines the offset information based on the threshold information The information is used for subsequent judgments. Optionally, the first threshold may be the first threshold reconfigured when the terminal device enters the connected state. Optionally, the first threshold may be a threshold of the terminal device in the idle state, and the terminal device uses the threshold in the idle state by default to continue to be used for judgment.

Specifically, the first reference signal type may include a synchronization signal block (Synchronization Signal Block, SSB) and a channel state information reference signal (Channel State Information-Reference Signal, CSI-RS). It should be noted that when the terminal device is in the idle state or inactive state, the terminal device may be configured with SSB signals, and when the terminal device is in the connected state, the terminal device may be configured with SSB signals and/or CSI-RS signals.

It should be noted that, in the idle state or the inactive state, the terminal device measures the SSB signal, and in the connected state, the terminal device can measure the SSB signal, and the terminal device can also measure the CSI-RS signal.

In some embodiments, the network device sends first indication information to the terminal device, where the first indication information is used to indicate a first reference signal type. Optionally, the network device may also separately send the first threshold information to the terminal device in information other than the first indication information, where the first threshold information is used to indicate the first threshold corresponding to the first reference signal type indicated by the first indication information. a threshold. Optionally, the network device may not send the first threshold information to the terminal device, and the terminal device defaults to the first threshold. For example, in the connected state, the terminal device receives the first indication information sent by the network device, and the first indication information indicates that the first reference signal type is an SSB signal. If the terminal device does not receive the first threshold information, the terminal device defaults to using The threshold corresponding to the SSB signal in the idle state; for another example, in the connected state, the terminal device receives the first indication information sent by the network device, the first indication information indicates that the first reference signal type is an SSB signal, and the terminal device also receives The first threshold information sent by the network device, the terminal device uses the first threshold indicated by the first threshold information to judge whether the measured value measured using the SSB signal meets the first criterion; for another example, in the connected state, the terminal device receives The first indication information sent by the network device, the first indication information indicates that the first reference signal type is a CSI-RS signal, and the terminal device also receives the first threshold information sent by the network device, then the terminal device uses the first threshold information to indicate The first threshold value is used to determine whether the measured value measured using the CSI-RS signal satisfies the first criterion. It should be noted that the first threshold information may be included in a system message, and the first indication information and the first threshold information are two different messages.

In some embodiments, the network device sends a piece of first indication information to the terminal device, where the first indication information is used to indicate a reference signal type and a threshold corresponding to the reference signal type. In a possible implementation manner, multiple fields are predefined, each field corresponds to a reference signal type, each field corresponds to a piece of first indication information, and the value of the field is a threshold value of its corresponding reference signal type. For example, two fields are predefined, field A and field B. Field A corresponds to the SSB signal, and field B corresponds to the CSI-RS signal. When the terminal device receives a first indication information, the first indication information is located in field A, then the The first indication information is used to indicate that the SSB signal is used for measurement. The value of field A is the threshold corresponding to the SSB signal. The terminal device uses the threshold corresponding to field A to determine whether the measurement value measured using the SSB signal meets the first criterion.

In some embodiments, the network device sends two or more first indication information to the terminal device, where each first indication information is used to indicate a reference signal type and a threshold corresponding to the reference signal type. For example, two fields are predefined, field A and field B. Field A corresponds to the SSB signal, and field B corresponds to the CSI-RS signal. When the terminal device receives two first indication information, which are respectively located in field A and field B, the terminal The device may select one of the two reference signal types indicated by the first indication information to determine the first criterion. For example, when the terminal device chooses to use the SSB signal, the terminal device uses the threshold corresponding to field A to judge whether the measured value measured using the SSB signal meets the first criterion; when the terminal device chooses to use the CSI-RS signal, the terminal device uses the threshold corresponding to field B. The threshold value of is used to determine whether the measurement value measured using the CSI-RS signal satisfies the first criterion.

In some embodiments, when the terminal device is in the connected state, the first indication information may be sent separately through broadcast or dedicated signaling, and the dedicated signaling may be a radio resource control (Radio Resource Control, RRC) reconfiguration message, Or media access control (Medium Access Control, MAC) control element (Control Element, CE) MACCE and other messages, which are not particularly limited in this embodiment of the present application.

In some embodiments, when the terminal device is in the connected state, the first indication information may be included in the measurement configuration information or the reporting configuration information, and the content indicated by the first indication information may be reported based on event triggering or periodic reporting The events are defined in the escalation list. The first indication information may also be carried in an RRC reconfiguration message.

In some embodiments, the first reference signal type indicated by the first indication information may be an implicit indication, for example, when the terminal device is in the connected state, all the measurement configuration information received by the terminal device indicates that the terminal When the device uses the SSB signal for measurement or reporting, the terminal device does not receive the first indication information but uses the SSB signal to perform the measurement for the first determination by default, or, when the terminal device is in the connected state, the measurement received by the terminal device All of the configuration information indicates that when the terminal device uses the CSI-RS signal to perform measurement or report, the terminal device does not receive the first indication information but uses the CSI-RS signal to perform measurement for the first determination by default.

It should be noted that other measurement requirements are configured in the measurement configuration information. For another example, when the terminal device is in the connected state, the SSB signal is used by default to perform the measurement for the first determination, and the network device does not need to send the first indication information to indicate the type of the first reference signal.

It should be noted that, if the first indication information is received, the default SSB signal is not used to perform the measurement of the first determination. Correspondingly, the first reference signal type indicated by the first indication information is used for the first determination. A judgmental measurement. For another example, when the terminal device is in the idle state or inactive state, the network device broadcasts first indication information to the terminal device. Optionally, the first reference signal type indicated by the first indication information is an SSB signal. Optionally, The first reference signal type indicated by the first indication information is a CSI-RS signal. Correspondingly, when the terminal device enters the connected state from the idle state or the inactive state, the measurement may be continued according to the first reference signal type indicated by the first indication information received in the idle state.

Specifically, the first criterion may include a stationary criterion and a not-at-the-cell-edge criterion. It should be noted that the stationary criterion and the not-at-the-cell-edge criterion can evaluate the approximate location and mobility information of the terminal device to a certain extent.

Specifically, the relationship between the first measured value and the first threshold (or the offset of the first threshold) satisfies the static criterion, then the relationship between the first measured value of the reference signal of the first reference signal type and the first threshold satisfies the following relation:

For the first reference signal type is SSB signal:

(Srxlev _Ref −Srxlev)<S _SearchDeltaP , where S _SearchDeltaP is the first threshold corresponding to the SSB signal, that is, the threshold evaluation criterion is used when the SSB signal is used for measurement. Srxlev is the reference signal receiving power (Reference Signal Receiving Power, RSRP) quality of the current serving cell, that is, the first measurement value, and Srxlev _Ref is the reference RSRP quality of the current serving cell.

Optionally, when the relationship between the first measured value measured by the terminal device and the first threshold satisfies the above formula or the maintenance time of the static criterion is greater than or equal to the first time, the terminal device judges that the first measured value of the SSB signal and the first The relationship between the thresholds satisfies the static criterion. It should be noted that the specific name of the first time may be TSearchDeltaP or Tin, and the name of the first time is not limited in this embodiment of the present application.

It should be noted that the first time may be a maintenance time configured by the network device to the terminal device to satisfy the static criterion.

It should be noted that the first time may be the time configured by the network device to the terminal device in an idle state. The first time may also be the time configured by the network device to the terminal device in the connected state. It should be noted that the first time when the network device configures the terminal device in the idle state and the connected state may be the same or different. Optionally, if the network device does not configure the first time to the terminal device in the connected state or the network device instructs the terminal device to use the configuration in the idle state or broadcast, the terminal device may use the first time configured in the idle state.

It should be noted that the network device can also configure the terminal device with a second time for the maintenance time that does not meet the static criterion, which is used for the terminal device to judge whether to leave the measurement relaxation state. The specific name of the second time can be Tout, which is not discussed in this application. Do limited. The present application will describe the second time below, and details will not be repeated here.

It should be noted that the first time may be greater than the second time, so that the measurement relaxation state can be left more quickly and the performance of the terminal device in the connected state can be guaranteed. Optionally, the first time may also be equal to the second time, or the first time may be less than the second time, which is not limited in this embodiment of the present application.

Optionally, the first time of the maintenance time meeting the static criterion and the second maintenance time not meeting the static criterion may be configured through an RRC message. Optionally, the first time of the maintenance time that meets the static criterion and the second time of the maintenance time that does not meet the static criterion can be configured through the report configuration in the measurement configuration, that is, the network device can send the first time and the second time to the terminal device at the same time. The configuration information of the second time, specifically, a manner in which the network device simultaneously configures the first time and the second time to the terminal device may be that the first time and the second time are two trigger times of a measurement event.

Optionally, if the relationship between the measured value and the first threshold does not satisfy the first criterion within the third time, the terminal device sets Srxlev of the camping cell or the serving cell as Srxlev _Ref . Optionally, the third time is indicated by the network device to the terminal device. Optionally, the third time is defaulted by the terminal device. The third time may be the same as the first time or the second time. It should be noted that for the criterion of not being at the edge of a cell, there is a similar configuration of the maintenance time, and reference can be made to the configuration of the maintenance period of the above static criterion, which will not be repeated in this embodiment of the present application.

For the first reference signal type is a CSI-RS signal:

(Srxlev _Ref –Srxlev)<S _{SearchDeltaPCSI} , or,

(Srxlev _Ref -Srxlev)<S _SearchDeltaP +offset _CSI , wherein, S _{SearchDeltaPCSI} is the first threshold indicated by the first indication information received in the connected state, and S _SearchDeltaP is the threshold received when the idle state or the inactive state, In some embodiments, the threshold is the threshold of the SSB signal, and the offset _CSI is the offset received in the connected state. Specifically, the name of the threshold value and the offset value in the embodiment of the present application is only an example of a name, and other names may also be used, which is not limited in the embodiment of the present application.

Specifically, the relationship between the first measured value and the first threshold (or the offset of the first threshold) satisfies the not-at-the-cell-edge criterion, then the relationship between the first measured value and the first threshold satisfies the following relationship:

Wherein, S _{SearchThresholdP} and S _{SearchThresholdQ} are thresholds received when idle state or inactive state, in some embodiments, this threshold is the threshold value of SSB signal, offset _CSI is the offset amount received when connected state, S _{SearchDeltaPCSI} and S _{SearchThresholdQCSI} are the first thresholds indicated by the first indication information received in the connected state. The threshold received in the idle state is the threshold broadcast in the system message.

It should be noted that, in some embodiments, when the terminal device is in the idle state, the first judgment is made according to the threshold value of the broadcasted SSB signal. When the terminal device enters the connection state from the idle state, the network device may indicate the terminal device to measure the reference The signal type is SSB signal or CSI-RS signal. When indicating that the measured signal is an SSB signal, the threshold value of the SSB signal in the idle state can be extended, or the first threshold value of the SSB signal can be re-indicated. When the signal measured is indicated When it is a CSI-RS signal, the offset amount may be indicated based on the threshold of the SSB signal in the idle state, or the first threshold of the CSI-RS signal may be re-indicated, which is not particularly limited in the present application.

It should be noted that, in some cases, the network device may also instruct the terminal device whether the measurement meets other criteria, which is not limited in this application. Optionally, the other criterion may assist the network device in judging whether to make the terminal device enter the measurement relaxed state.

S220. In the connected state, the terminal device measures the reference signal of the first reference signal type according to the first indication information, so as to acquire a first measurement value.

Specifically, the terminal device receives the first indication information, determines the first reference signal type used for the first determination, and the terminal device measures the reference signal of the first reference signal type.

The terminal device may perform n measurements on the serving cell, the n measurements may be arranged according to the measurement time, and the n is greater than or equal to 1.

The terminal device can measure m neighboring cells of the serving cell, where m is greater than or equal to 1.

S230. The terminal device sends second indication information to the network device, where the second indication information is used to indicate that the relationship between the first measurement value and the first threshold satisfies the first criterion.

In some embodiments, the second indication information is sent to the network device as a separate signaling, which may be sent to the network device through a terminal equipment assistance information (UEAssisitanceInformation) message, or may be sent to the network device through MAC CE information. The second indication information is used to indicate that the relationship between the first measurement value and the first threshold satisfies the first criterion. Optionally, the terminal device may perform at least n measurements on the serving cell, and report the measurement results satisfying the first criterion. , the n measurements may be sorted according to the measurement time. Optionally, the terminal device may also perform measurements on m neighboring cells, and report the measurement results satisfying the first criterion.

In some embodiments, the second indication information is sent to the network device in the measurement report of the terminal device. Optionally, the terminal device may perform n measurements on the serving cell, and report the measurement results satisfying the first criterion. The n measurements may be sorted according to the time of measurement. Optionally, the terminal device may also perform m neighboring cells, and report the measurement results satisfying the first criterion.

In some embodiments, the terminal device reports the measurement results of n serving cells, and the measurement results of the n serving cells may be n results satisfying the criterion, or, after satisfying the criterion, the reported n measuring results include not Measurement results that meet the criteria.

In some embodiments, when the first criterion is met, the terminal device reports the measurement results of m neighboring cells. Reporting the result can enable the network device to obtain more information about the terminal device to determine whether to allow the terminal to perform measurement relaxation.

S240. The network device sends third indication information to the terminal device, where the third indication information is used to instruct the terminal device to enter a measurement relaxation state.

It should be noted that this step is optional. If the network device determines that the terminal device cannot enter the measurement relaxation state according to the second indication information, the network device may not send the third indication information to the terminal device.

Specifically, the network device receives the second indication information. Optionally, the network device evaluates the approximate location and mobility information of the terminal device according to the measurement results of the serving cell in the second indication information. Optionally, the network device evaluates the approximate location and mobility information of the terminal device according to the second indication information. 2. Indicate the measurement result of the adjacent cell in the indication information, and judge whether the handover of the terminal equipment may occur.

Specifically, when the network device determines that the terminal device can perform measurement relaxation according to the second indication information, it sends third indication information to the terminal device, where the third indication information is used to instruct the terminal device to enter the measurement relaxation state. The third indication information may be an RRC message, for example, an RRC reconfiguration message, or may be a MAC CE message or the like.

It should be understood that the content of the measurement relaxation may be frequency measurement relaxation, cell measurement relaxation, period measurement relaxation, and the like. Specifically, the third indication information may include: the frequency that needs to be measured, or the frequency that needs to be relaxed, or the cell that needs to be measured, or the cell that needs to be relaxed, or the cycle of the measurement (such as the cycle is seconds, minutes, hours, etc.) . In other words, after the terminal device enters the measurement relaxation state, it can relax the measurement cycle, and the network device can instruct the terminal device to relax the measurement cycle. As an example and not a limitation, the original measurement cycle is once every 5 minutes, and enter the measurement relaxation state In the future, the measurement cycle can be measured once every 10 minutes. After the terminal device enters the measurement relaxation state, it may perform measurement relaxation on a certain frequency. As an example and not a limitation, the terminal device may not perform measurement on the frequency. After the terminal device enters the measurement relaxation state, it may perform measurement relaxation on a certain cell. As an example but not a limitation, the terminal device may not perform measurement on the cell.

It should be noted that the content for the terminal device to enter the measurement relaxation state may also be a combination of the above three types. As an example and not a limitation, the network device may instruct the terminal device that for a certain cell A, the measurement period is once every 20 minutes, and for a certain cell A, the measurement period is once every 20 minutes. A cell B, the measurement period is once every 10 minutes, the content of the measurement relaxation can be specifically indicated by the third indication information of the network device, or the third indication information can indicate to enter the measurement relaxation state and the terminal equipment side defaults to the measurement relaxation Content. The third indication information may be an RRC reconfiguration message.

Optionally, the terminal device uses the SSB signal to perform measurement or the CSI-RS signal to perform measurement, and after receiving the third indication information, measurement relaxation can be performed on related measurements corresponding to the two types of reference signals. Optionally, the terminal device uses the SSB signal to perform measurement, receives the third indication information, and performs measurement relaxation on related measurement corresponding to the SSB signal. Optionally, the terminal device uses the CSI-RS signal to perform measurement, receives the third indication information, and performs measurement relaxation on related measurement corresponding to the CSI-RS signal.

In some embodiments, the third indication information may carry a measurement ID, a measurement object ID, etc., and is used to indicate that the measurement object corresponding to the ID should be relaxed. It is also possible to indicate which reference signal the measurement relaxation is performed on.

It should be noted that after the terminal device enters the measurement relaxed state in the connected state, when the first condition is met, the terminal device needs to leave the measurement relaxed state in time to ensure the mobility performance of the terminal device in the connected state.

In this embodiment of the present application, the static criterion is used as an example to illustrate the first condition for the terminal device to leave the measurement relaxation state. It should be understood that the criterion of not being at the cell edge may also have a similar first condition for the terminal device to determine to leave the measurement relaxation state, which is not described in this embodiment of the present application, but is not limited in this embodiment of the present application.

In a possible implementation manner, taking the stationary criterion as an example, the first condition may be that the terminal device determines that the relationship between the first measurement value of the reference signal of the first reference signal type and the first threshold does not satisfy the stationary criterion formula The maintenance time reaches the preset second time, that is, the relationship between the first measured value and the first threshold does not satisfy the formula of the stationary criterion within the second time, or the formula of the leaving condition of the stationary criterion is satisfied within the second time. Specifically, the value of the second time may be 0. The departure condition for the stationary criterion will be described in method 400, and will not be repeated here.

In a possible implementation manner, taking the static criterion as an example, the first condition may be that the terminal device receives indication information sent by the base station, where the indication information instructs the terminal device to leave the measurement relaxation state.

In a possible implementation manner, the first condition may be that the terminal device judges that the measurement relaxation time preset by the base station has been reached. Optionally, when the base station sends the third indication information to the terminal device, it may carry timer information to indicate the measurement relaxation time of the terminal device. When the timer expires, the terminal device ends the measurement relaxation state.

In a possible implementation, taking the static criterion as an example, the first condition may be a trigger condition for terminal equipment to reuse certain events, such as the trigger condition for measurement reporting events defined in 3GPP protocols such as A3, A4, and A5 . The following will briefly introduce events such as A3, A4, and A5.

Specifically, the entry condition A3-1 of the A3 event satisfies the formula:

Mn+Ofn+Ocn–Hys>Mp+Ofp+Ocp+Off

The departure condition A3-2 of the A3 event satisfies the formula:

Mn+Ofn+Ocn+Hys<Mp+Ofp+Ocp+Off

Among them, Mn is the measurement result of the adjacent cell, Ofn is the specific offset amount realized by the reference signal measurement of the adjacent cell, Ocn is the cell-specific offset amount of the adjacent cell, Mp is the measurement result of the serving cell, and Ofp is the measurement object of the serving cell Specific offset amount, Ocp is the cell-specific offset amount of the serving cell, Hys is the hysteresis amount, and Off is the event offset amount.

Specifically, the entry condition A4-1 of the A4 event satisfies the formula:

Mn+Ofn+Ocn–Hys>Thresh

The departure condition A4-2 of the A4 event satisfies the formula:

Mn+Ofn+Ocn+Hys<Thresh

Where Thresh is the threshold of the A4 event. Other definitions are the same as above.

Specifically, the entry condition A5-1 of the A5 event satisfies the formula:

Mp+Hys<Thresh1, or

Mn+Ofn+Ocn–Hys>Thresh2

The departure condition A5-2 of the A5 event satisfies the formula:

Mp–Hys>Thresh1, or

Mn+Ofn+Ocn+Hys<Thresh2

Wherein, Thresh1 and Thresh2 are the thresholds of the event, and other definitions are the same as above.

It should be noted that the events A3, A4, and A5 may be measurement events for switching configurations, or may be measurement events applicable to other situations, which are not limited in this embodiment of the present application.

Taking the A3 event as an example, when the measurement result of the terminal device satisfies the formula defined by the entry condition of the A3 event, the terminal device can judge to leave the measurement relaxation state. Optionally, the measurement result may not satisfy the trigger time configuration (timetotrigger) configured by the network device in the A3 event, that is, only the formula condition in the A3 event is reused, and the trigger time in the A3 event is not reused. Optionally, the measurement result of the terminal device may only meet the formula condition of the A3 event, and the trigger time may use the time that does not meet the static criterion or the departure condition that meets the static criterion, that is, Tout or the second time, the cell quality measured by the terminal device , the formula defined by the A3 event is satisfied within the second time, then the measurement of relaxation can be stopped. Optionally, the measurement result may also meet the time threshold configured by the network device in the A3 event.

In a possible implementation manner, taking the static criterion as an example, the first condition may be that the terminal device determines to end the measurement of the relaxed state after triggering a certain event report.

Taking the A3 event as an example, when the terminal device triggers the reporting of the A3 event, the measurement relaxation state ends by default.

It should be understood that the terminal device may end the measurement relaxation state by itself after the first condition is met, and the terminal device may also send indication information to the network device after the first condition is met, and the indication information indicates the network device that the terminal device meets the first condition . After receiving the instruction information, the network device may decide whether to instruct the terminal device to end the measurement relaxation state. After the terminal device receives the instruction from the network device to end the measurement relaxation state, the terminal device ends the measurement relaxation state.

The technical solution provided by the embodiment of this application can indicate the type of the first reference signal of the terminal device when the terminal device enters the connected state, so that the terminal device can measure the reference signal of the first reference signal type based on the indication, and obtain the first measurement Value, and judge whether the relationship between the first measurement value and the first threshold meets the first criterion, the terminal device reports the judgment result to the network device, and the network device indicates whether the terminal device enters the measurement relaxation state according to the result, when entering the measurement relaxation state , which can save the power consumption of the terminal equipment in the connected state.

Fig. 3 is another example of the communication method of the embodiment of the present application. As shown in Figure 3, the method 300 includes:

S310. The network device sends first indication information to the terminal device, where the first indication information is used to indicate the first reference signal type.

Specifically, the first reference signal type may include a synchronization signal block (SynchronizationSignalBlock, SSB), and a channel state information reference signal (Channel State Information-Reference Signal, CSI-RS). It should be noted that when the terminal device is in the idle state or inactive state, the terminal device may be configured with SSB signals, and when the terminal device is in the connected state, the terminal device may be configured with SSB signals and/or CSI-RS signals.

It should be noted that, in the idle state or the inactive state, the terminal device measures the SSB signal, and in the connected state, the terminal device can measure the SSB signal, and the terminal device can also measure the CSI-RS signal.

Specifically, the first indication information may be used to indicate that the terminal device needs to perform a first determination on the reference signal of the first reference signal type, and the first determination is that the terminal device needs to determine the measured value and Whether the relationship between the first thresholds satisfies the first criterion.

In some embodiments, when the terminal device is in the connected state, the network device sends the first indication information to the terminal device. The first indication information may be sent through a broadcast message or through dedicated signaling, for example, wireless A resource control (Radio Resource Control, RRC) reconfiguration message, or a medium access control (Medium Access Control, MAC) control element (Control Element, CE) MAC CE, etc., which is not limited in this embodiment of the present application. The first indication information is used to instruct the terminal device to measure the SSB signal, or measure the CSI-RS signal, or measure other possible types of reference signals. It should be noted that the measurement is used for the first determination .

In some embodiments, when the terminal device is in the connected state, all the measurement configuration information received by the terminal device indicates that the terminal device uses the SSB signal to perform measurement or report, but the terminal device does not receive the first indication information but By default, the SSB signal is used for the measurement for the first determination, or, when the terminal device is in the connected state, all the measurement configuration information received by the terminal device indicates that the terminal device uses the CSI-RS signal for measurement or reporting. The device does not receive the first indication information but uses the CSI-RS signal by default to perform measurement for the first determination. It should be noted that other measurement requirements are configured in the measurement configuration information.

In some embodiments, when the terminal device is in the connected state, the SSB signal is used by default to perform the measurement for the first determination, and the network device does not need to send the first indication information to indicate the first reference signal type.

In some embodiments, when the terminal device is in an idle state or an inactive state, the network device broadcasts first indication information to the terminal device. Optionally, the first reference signal type indicated by the first indication information is an SSB signal, Optionally, the first reference signal type indicated by the first indication information is a CSI-RS signal. Correspondingly, when the terminal device enters the connected state from the idle state or the inactive state, the measurement may be continued according to the first reference signal type indicated by the first indication information received in the idle state.

It should be noted that, in the embodiment of the present application, the terminal device side protocol is adaptively modified, so that the terminal device performs the measurement and determination of the first determination after receiving the first indication information, without special measurement configuration information to configure.

It should be understood that the first indication information may also be used to indicate the first threshold or offset information. It should be noted that if the first indication information is used to indicate the offset information, the terminal device may be in the idle state or In the inactive state, the threshold information has been received once, and the terminal device combines the offset information with the threshold information for subsequent judgment. Optionally, the first threshold may be a first threshold reconfigured when the terminal device enters the connected state. Optionally, the first threshold may be a threshold when the terminal device is in the idle state.

In a possible implementation manner, when the terminal device is in the connected state, the network device sends first indication information to the terminal device, where the first indication information indicates the first threshold, or the first indication information indicates the value of the first threshold The offset, the first threshold, or the first offset is the first threshold or offset related to the SSB signal, then the terminal device defaults to the measurement of the SSB signal for the first determination, if the first threshold , or the offset of the first threshold is the first threshold or offset related to the CSI-RS, then the terminal device performs measurement on the CSI-RS signal for the first determination by default. In this implementation manner, it may not be necessary to separately indicate the first signal type.

Specifically, the terminal device measures a reference signal of the first reference signal type to obtain a first measurement value, and the terminal device determines whether the relationship between the first measurement value and the first threshold satisfies a first criterion, and the first criterion may include static Criterion, not at the cell edge criterion. It should be noted that the stationary criterion and the not-at-the-cell-edge criterion can evaluate the approximate location and mobility information of the terminal device to a certain extent.

It should be noted that, for the relationship between the first measured value and the first threshold to satisfy the first criterion, reference may be made to the description of step S210 in the method 200 , which will not be repeated here.

Network device Network device S340, the terminal device sends second indication information to the network device, where the second indication information is used to indicate the result of the first determination.

In some embodiments, the terminal device determines that the relationship between the first measurement amount and the first threshold satisfies the first criterion, and the terminal device sends second indication information to the network device, where the second indication information is used to indicate the first measurement amount and the first The relationship between the thresholds satisfies the first criterion.

Optionally, the terminal device may also perform measurements on multiple neighboring cells. And report whether the measurement results of the m neighboring cells with the best quality of the cell meet the first criterion, where m and n are positive integers.

It should be noted that the second indication information may be sent to the network device through a terminal device auxiliary information message, or may be sent to the network device through MAC CE information.

It should be noted that, after the terminal device sends the second indication information to the network device, but does not receive the third indication information sent by the network device, the terminal device may wait for the first time before sending the second indication information again, and the first time may be It is sent by the network device to the terminal device before, or it may be default or pre-configured by the terminal device or stipulated by the protocol. Optionally, the terminal device may also stop sending the second indication information to the network device after it still has not received the third indication information from the network equipment after reporting L times. The one sent by the terminal device may also be the default one of the terminal device. After the terminal device stops sending the second indication information, if it receives the first indication information again, the terminal device performs measurement again and sends the second indication information according to the judgment result.

Optionally, before the terminal device reports the indication information, the network device may configure the terminal device with the maximum number of reports L after meeting the first criterion. When the terminal device meets the first criterion, it starts to send the second indication information to the network device. The sending cycle Configured for network devices or the default configuration for terminal devices. Specifically, if the relaxation indication information is received in the process of sending the configuration, the terminal device stops sending the second indication information, and starts to measure the relaxation. The L times of measurement results reported by the terminal device may all satisfy the first criterion, or may not satisfy the first criterion.

Optionally, after the terminal device sends the second indication information to the network device, but does not receive the third indication information sent by the network device, the terminal device may start a timer, and when the timer expires, judge again whether the first criterion is satisfied, If it is satisfied, the second indication information is sent again, and if it is not satisfied, it does not need to be sent. The timer may be previously sent by the network device to the terminal device, or may be specified by a protocol.

Optionally, after determining that the first criterion is met, the terminal device may decide whether to perform measurement relaxation without notifying the network device. Alternatively, after deciding whether to perform measurement relaxation, the second indication information is sent to the network device, and whether measurement relaxation has been performed.

S350. The network device sends third indication information to the terminal device, where the third indication information is used to instruct the terminal device to enter a measurement relaxation state.

It should be noted that this step is optional. If the network device determines that the terminal device cannot enter the measurement relaxation state according to the second indication information, the network device may not send the third indication information to the terminal device.

Specifically, the network device receives the second indication information. Optionally, the network device evaluates the approximate location and mobility information of the terminal device according to the measurement results of the serving cell in the second indication information. Optionally, the network device evaluates the approximate location and mobility information of the terminal device according to the second indication information. 2. Indicate the measurement result of the adjacent cell in the indication information, and judge whether the handover of the terminal equipment may occur.

Specifically, when the network device determines that the terminal device can perform measurement relaxation according to the second indication information, it sends third indication information to the terminal device, where the third indication information is used to instruct the terminal device to enter the measurement relaxation state. The third indication information may be an RRC message, for example, an RRC reconfiguration message, or may be a MAC CE message or the like.

It should be understood that the content of the measurement relaxation may be frequency measurement relaxation, cell measurement relaxation, period measurement relaxation, and the like. In other words, after the terminal device enters the measurement relaxation state, it can relax the measurement cycle, and the network device can instruct the terminal device to relax the measurement cycle. As an example and not a limitation, the original measurement cycle is once every 5 minutes, and enter the measurement relaxation state In the future, the measurement cycle can be measured once every 10 minutes. After the terminal device enters the measurement relaxation state, it may perform measurement relaxation on a certain frequency. As an example and not a limitation, the terminal device may not perform measurement on the frequency. After the terminal device enters the measurement relaxation state, it may perform measurement relaxation on a certain cell. As an example but not a limitation, the terminal device may not perform measurement on the cell.

It should be noted that the content for the terminal device to enter the measurement relaxation state may also be a combination of the above three types. As an example and not a limitation, the network device may instruct the terminal device that for a certain cell A, the measurement period is once every 20 minutes, and for a certain cell A, the measurement period is once every 20 minutes. A cell B, the measurement period is once every 10 minutes, the content of the measurement relaxation can be specifically indicated by the third indication information of the network device, or the third indication information can indicate to enter the measurement relaxation state and the terminal equipment side defaults to the measurement relaxation Content.

Optionally, the terminal device uses the SSB signal to perform measurement or the CSI-RS signal to perform measurement, and after receiving the third indication information, measurement relaxation can be performed on related measurements corresponding to the two types of reference signals. Optionally, the terminal device uses the SSB signal to perform measurement, receives the third indication information, and performs measurement relaxation on related measurement corresponding to the SSB signal. Optionally, the terminal device uses the CSI-RS signal to perform measurement, receives the third indication information, and performs measurement relaxation on related measurement corresponding to the CSI-RS signal.

Optionally, the third indication message may be only measurement configuration information, that is, measurement objects or cells or frequency points that need to be measured are reduced through implementation.

It should be understood that the sending of the third indication information by the network device to indicate that the periodic measurement is relaxed may be specifically indicated in the form of the network device sending a reference signal measurement configuration to the terminal device.

Specifically, the network device may send two sets of SMTC (SS/PBCH block measurement timing configuration, SSB measurement timing configuration) configurations to the terminal device, that is, the first SMTC configuration and the second SMTC configuration. Wherein, the first SMTC configuration may be used when the terminal device does not enter the measurement relaxed state, and the second SMTC configuration may be used when the terminal device enters the measurement relaxed state. The first SMTC configuration and the second SMTC configuration may be configured in the same message, or may be configured in different messages. Optionally, the message may be an RRC reconfiguration message.

It should be understood that the SMTC configuration is used to instruct the terminal device to measure the timing of the SSB signal, specifically, the SMTC configuration includes a measurement period and an offset. It should be noted that the offset information is used to indicate the starting position of the SMTC in the measurement period, for example, from which time slot, subframe, or symbol the SMTC measurement period starts. Optionally, the measurement period indicated by the second SMTC configuration may be longer than the measurement period indicated by the first SMTC configuration, so that the terminal device can save power consumption when measuring the relaxed state.

Optionally, the SMTC configuration may carry an SMTC ID, which is used to indicate that the SMTC configuration is the first SMTC configuration or the second SMTC configuration.

Optionally, the second SMTC configuration may be indicated by a dedicated field. If this field exists, the terminal device is configured with configuration information that meets the first criterion for relaxed use of measurement. This field may be included in the measurement object configuration of the measurement configuration.

It should be noted that the second SMTC configuration can be configured synchronously with the configuration message of the first criterion when the terminal device does not meet the first criterion; the second SMTC configuration can be configured again when the terminal device meets the first criterion. Optionally, when the terminal device satisfies the first criterion, the network device may send indication information to the terminal device, where the indication information instructs the terminal device to use the second SMTC configuration for measurement. It should be understood that the instruction information may be equivalent to the above third instruction information, that is, the network device sends to the terminal device to use the second SMTC configuration for measurement to implicitly instruct the terminal device to enter the measurement relaxation state and use the second SMTC configuration for measurement. If the terminal device has not been configured with the second SMTC configuration before, the second SMTC configuration may be included in the indication information. If yes, after receiving the indication information, the terminal device uses the second SMTC configuration to perform relaxed measurement.

It should be understood that after the network device instructs the terminal device to enter the measurement relaxation state, the change of the measurement content may be reflected in the form of a change in the SMTC configuration, that is, the network device configures a different SMTC configuration for the terminal device after the terminal device enters the measurement relaxation state.

Optionally, the network device may only configure the first SMTC configuration for the terminal device. When the terminal device enters the measurement relaxation state, the network device may send an indication message indicating that the measurement period in the first SMTC configuration of the terminal device is changed, for example , the network device can instruct the terminal device to set the measurement period in the first SMTC configuration to be x times the original, or, by default in the protocol, when the terminal device is in the measurement relaxation state, the used period is x times the measurement period when it is not in the measurement relaxation state , when the terminal device enters the measurement relaxation state or receives the third indication information, it uses the cycle corresponding to the measurement relaxation state to perform measurement.

In a possible implementation manner, the resource configuration of each CSI-RS in the CSI-RS resource configuration set includes configurations such as CSI-RS index, period, and offset. Similar to the above SMTC resource configuration, the CSI-RS resource configuration set may include a first CSI-RS configuration and a second CSI-RS configuration, wherein the first CSI-RS configuration is used when the terminal device is not in the measurement relaxation state , the second CSI-RS configuration is used by the terminal device when measuring the relaxed state. It should be noted that the protocol predefines to configure the first CSI-RS configuration in the A field, and configure the second CSI-RS configuration in the B field. Then the terminal device defaults that the configuration of field A is the first CSI-RS configuration, and the configuration of field B is the CSI-RS configuration. The network device may configure the first CSI-RS configuration and the second CSI-RS configuration at the same time when the terminal device does not enter the measurement relaxation state, or the network device may first configure the first CSI-RS configuration when the terminal device does not enter the measurement relaxation state , and then configure the second CSI-RS when the terminal device enters the measurement relaxed state, or the network device can first configure the first CSI-RS configuration when the terminal device does not enter the measurement relaxed state, and indicate that the terminal device enters the measurement relaxed state.

Optionally, the terminal device may decide to end the measurement relaxation state by sending the fourth indication information, that is, the measurement relaxation may be terminated when it is determined that the first criterion is not satisfied. It can be before or after sending the fourth message. It is also possible to wait for fifth indication information from the network device, where the fifth indication information is used to instruct the terminal equipment to end the measurement relaxation state.

Optionally, in step S350, the third indication information sent by the network device may include a timer configuration, and the timer configuration may also be the default configuration of the terminal. After receiving the third indication information, the terminal device enters the measurement relaxation state The timer is started at the same time, and when the timer reaches the first duration, the terminal device ends the measurement relaxation state. It should be noted that if the terminal device finds that the relationship between the measurement amount and the first threshold does not meet the first criterion within the first time period, it can send the fourth indication information to the network device, and decide to end the measurement relaxation state or wait for the network device's response. The fifth indication message ends measuring the relaxed state.

Optionally, in step S350, the third indication information sent by the network device may include a timer configuration, and the timer configuration may also be a default configuration of the terminal. After the terminal device receives the third indication information, it enters the measurement relaxation state and starts the timer at the same time. Before the timer reaches the first duration, the terminal device finds that the relationship between the measurement quantity and the first threshold does not satisfy the first criterion, and does not Send the fourth instruction information to the network device, and when the timer reaches the first duration, the terminal device sends the fourth instruction information to the network device, decides to end the measurement relaxation state by itself or waits for the fifth instruction information from the network device to end the measurement relaxation state.
