The present application claims priority of chinese patent application with application number 202110854658.9, entitled "communication method and communication apparatus", filed by the chinese intellectual property office of china on 28/7/2021, the entire contents of which are incorporated herein by reference.

Technical Field

The present application relates to the field of communications, and in particular, to a communication method and a communication apparatus.

Background

With the rapid development of wireless communication, fifth generation mobile communication (5g) systems are being developed to meet and enrich the growing demand of people. The method can effectively cope with the explosive mobile data flow increase in the future, and support massive equipment connection and various new services emerging continuously.

The Internet of Things (IoT) is a 5G component, and its market demand is growing rapidly. Machine to Machine, M2M, is a short for mutual information and data transmission between machines through a wireless network, and is an important direction of IoT development. Most of the M2M devices are relatively small and battery-powered systems, such as an intelligent meter reading system, and the usage conditions of water, electric gas and the like need to be periodically monitored and reported. In 5G, a reduced capability terminal is also an IoT device, with low power consumption and low complexity requirements. Therefore, in the internet of things system, a new scheme needs to be designed so that the terminal device achieves lower power consumption.

Disclosure of Invention

When the terminal equipment is in a connected state, a first reference signal type measured by the terminal equipment is indicated through first indication information, the terminal equipment measures a reference signal of the first reference signal type according to the first indication information to obtain a first measured value, and the terminal equipment reports to network equipment when determining that the relation between the first measured value and a first threshold meets a first criterion. And the terminal equipment in the connected state can also judge and report the first criterion. In some cases, the network device may instruct the terminal device to enter a measurement relaxed state such that the terminal device achieves low power consumption while in a connected state.

In a first aspect, a communication method is provided, including: the method comprises the steps that terminal equipment receives first indication information sent by network equipment, wherein the first indication information is used for indicating the terminal equipment to carry out first judgment on a reference signal of a first reference signal type, and the first judgment is used for judging whether the relation between the measurement value of the reference signal of the first reference signal type and a first threshold value meets a first criterion or not; the terminal equipment measures a reference signal of a first reference signal type according to the first indication information in a connection state to obtain a first measurement value; and the terminal equipment sends second indication information to the network equipment, wherein the second indication information is used for indicating that the relation between the first measurement value and the first threshold meets the first criterion.

The method comprises the steps of sending first indication information to the terminal equipment, enabling the terminal equipment to know which reference signal is used for measurement, judging whether the relation between a first measurement value obtained through measurement and a first threshold value meets a first criterion, enabling the terminal equipment in a connection state to judge whether the relation meets the first criterion, and reporting a measurement result to the network equipment.

The first criterion may include a static criterion and/or an out-of-cell-edge criterion. The first criterion may be used to evaluate the approximate location of the terminal device and mobility information.

The first indication information is sent by the network device to the terminal device through broadcast or dedicated signaling, and the first indication information may be indicated in the form of measurement configuration information or a measurement event newly defined in reporting configuration information.

The first indication information sent by the network equipment to the terminal equipment can be indicated in various forms, and a flexible indication method is provided.

The first reference signal type may include a synchronization signal block SSB and/or a channel state information reference signal CSI-RS.

With reference to the first aspect, in some implementation manners of the first aspect, the terminal device receives third indication information sent by the network device, where the third indication information is used to indicate that the terminal device enters a measurement relaxed state in a connected state, and the terminal device enters the measurement relaxed state in the connected state, so that power consumption of the terminal device in the connected state may be reduced.

Optionally, the third indication information may further include timer information, where the timer information is used to indicate a duration for the terminal device to enter the measurement relaxed state. During the running of the timer, the terminal device performs measurement relaxation. And if the terminal equipment judges that the first criterion is not met during the running period of the timer, or the timer is overtime, the terminal equipment stops measuring and relaxing. This way, the controllability of the network device to the terminal device is enhanced, so that the measurement relaxation is performed under the control of the network device.

On the other hand, the network device may also actively send a stop or start measurement relaxation indication to the terminal device. The controllability of the network device is realized.

With reference to the first aspect, in certain implementations of the first aspect, the first indication information is further used to indicate a first threshold. Optionally, the first threshold may be indicated in the first indication information in the connected state. Optionally, the first threshold may be a threshold in an idle state, and when the connected state is entered, the first threshold in the idle state is also used by default. Optionally, the first indication information indicates offset information, and the first threshold is equivalent to the sum of the idle state threshold and the offset.

With reference to the first aspect, in some implementations of the first aspect, the first measurement value is a measurement value obtained by measuring, by the terminal device, a reference signal of a first reference signal type of a serving cell, or the first measurement value is a measurement value obtained by measuring, by the terminal device, a reference signal of a first reference signal type of a neighboring cell.

After receiving the measurement result, the network device can evaluate the approximate position and mobility information of the terminal device, and further judge whether to enable the terminal device to perform connection state measurement relaxation, so that the network device indicates according to the communication state of the terminal device, and the controllability of the network device is realized. With reference to the first aspect, in some implementations of the first aspect, the third indication information may include specific measurement relaxation contents, for example, relaxation of a measurement period, measurement in a longer period, relaxation of a measurement cell, no measurement of some cells, relaxation of a measurement frequency, and no measurement of some frequencies.

The third indication information indicates specific measurement relaxation content, so that the terminal device can flexibly determine the measurement relaxation content according to the indication of the network device, realize accurate measurement relaxation, and also realize the controllability of the network device.

With reference to the first aspect, in certain implementations of the first aspect, the first indication information or the third indication information is further used to indicate a measurement configuration of a reference signal of the first reference signal type in a measurement relaxed state, and the measurement configuration of the reference signal of the first reference signal type in the measurement relaxed state includes a first measurement period of the reference signal of the first reference signal type in the measurement relaxed state.

Optionally, the first indication information is further used to indicate a measurement configuration in which the reference signal of the first reference signal type is not in the measurement relaxed state, and the measurement configuration in which the reference signal of the first reference signal type is not in the measurement relaxed state includes a second measurement period in which the reference signal of the first reference signal type is not in the measurement relaxed state.

Optionally, the first measurement period is greater than the second measurement period. The terminal equipment can measure the reference signal in a longer period in a measurement relaxed state, and the power consumption of the terminal equipment is saved.

As an example, the network device may indicate, to the terminal device, that measurement relaxation is performed on the measurement period by using the configuration information of the measurement reference signal, for example, two or more sets of measurement configuration information are configured for the measurement reference signal, where the measurement period of each set of measurement configuration information is different, and when the terminal device meets the first criterion or enters a measurement relaxed state, the network device may indicate the terminal device to use different reference signal measurement configurations. For example, the network device may configure two sets of SMTC (SS/PBCH block measurement timing configuration, SSB measurement timing configuration) configurations for the terminal device, where the first SMTC configuration is used when measurement is not relaxed, and the second SMTC configuration is used when measurement is relaxed. Similarly, the network device may also configure similar measurement configuration information for the CSI-RS. Specifically, two sets of SMTC configurations correspond to one measurement frequency, or cell, or measurement object.

With reference to the first aspect, in certain implementations of the first aspect, the first determining to determine whether a relationship between a measurement value of a reference signal of the first reference signal type and a first threshold satisfies a first criterion includes: the first decision is for deciding that a relation between a measurement value of a reference signal of the first reference signal type and a first threshold satisfies a first criterion, or,

the first decision is to decide that a relationship between a measurement value of a reference signal of the first reference signal type and the first threshold value does not satisfy the first criterion for a second time.

That is, the determination that the relationship between the measured value of the first reference signal centroid and the first threshold value meets or does not meet the first criterion requires a certain time for the relationship to be determined.

Optionally, the first time is greater than or equal to the second time.

With reference to the first aspect, in some implementation manners of the first aspect, the second indication information sent by the terminal device to the network device may simultaneously report the measurement results of the terminal device for n times of measurements on the serving cell in one sending and reporting process, or may also simultaneously report the measurement results of the terminal device for m neighbor cells.

With reference to the first aspect, in some implementations of the first aspect, after the terminal device enters the measurement relaxed state, when it is determined that certain conditions are met, the terminal device may leave the measurement relaxed state by itself or leave the measurement relaxed state according to an instruction of the network device. As an example, the terminal device may leave the measurement relaxed state when a duration of time for which a relationship of the first measurement value and the first threshold does not satisfy the first criterion exceeds the second time. It is to be understood that the second time is less than the duration of time for which the terminal device determines that the relationship of the first measurement value and the first threshold satisfies the first criterion, i.e. the first time. The second time is set to be longer than the first time, so that the terminal equipment can leave the measurement relaxed state more quickly, and the performance of the terminal equipment in the connection state is ensured.

In a second aspect, a communication method is provided, including: the method comprises the steps that network equipment sends first indication information to terminal equipment, wherein the first indication information is used for indicating the terminal equipment to carry out first judgment on a reference signal of a first reference signal type, and the first judgment is used for judging whether the relation between the measurement value of the reference signal of the first reference signal type and a first threshold meets a first criterion or not; and the network equipment receives second indication information sent by the terminal equipment, wherein the second indication information is used for indicating that the relation between the first measurement value and the first threshold value meets a first criterion.

The method comprises the steps of sending first indication information to terminal equipment, enabling the terminal equipment to know which reference signal is used for measurement, then judging whether the relation between a first measurement value obtained through measurement and a first threshold value meets a first criterion, enabling the terminal equipment in a connection state to judge whether the relation meets the first criterion, and reporting a measurement result to network equipment.

The first criterion may include a static criterion and/or a non-cell-edge criterion. The first criterion may be used to evaluate the approximate location of the terminal device and mobility information.

The first indication information is sent by the network device to the terminal device by broadcasting or dedicated signaling, and the first indication information may also be indicated in the form of a measurement event newly defined in the measurement configuration.

With reference to the second aspect, in some implementation manners of the second aspect, the network device sends third indication information to the terminal device, where the third indication information is used to indicate that the terminal device enters a measurement relaxed state in a connected state, and the terminal device enters the measurement relaxed state in the connected state, so that power consumption of the terminal device in the connected state can be reduced.

With reference to the second aspect, in certain implementations of the second aspect, the first indication information is further used to indicate the first threshold. Optionally, the first threshold may be indicated in the first indication information in the connected state. Optionally, the first threshold may be a threshold in an idle state, and when entering the connected state, the first threshold in the idle state is also used by default. Optionally, the first indication information indicates offset information, and the first threshold is equivalent to the sum of the idle state threshold and the offset.

With reference to the second aspect, in some implementations of the second aspect, the first measurement value is a measurement value obtained by measuring, by the terminal device, a reference signal of the first reference signal type of the serving cell, or the first measurement value is a measurement value obtained by measuring, by the terminal device, a reference signal of the first reference signal type of the neighboring cell.

With reference to the second aspect, in some implementations of the second aspect, the third indication information may include specific measurement relaxation contents, for example, relaxation of a measurement period, measurement in a longer period, relaxation of a measurement cell, no measurement of some cells, relaxation of a measurement frequency, and no measurement of some frequencies.

With reference to the second aspect, in certain implementations of the second aspect, the first indication information or the third indication information is further used to indicate a measurement configuration of a reference signal of the first reference signal type in a measurement relaxed state, and the measurement configuration of the reference signal of the first reference signal type in the measurement relaxed state includes a first measurement period of the reference signal of the first reference signal type in the measurement relaxed state.

Optionally, the first measurement period is longer than the second measurement period. The terminal equipment can measure the reference signal in a longer period in a measurement relaxation state, and the power consumption of the terminal equipment is saved.

As an example, the network device indicating to the terminal device that the measurement period is relaxed may be indicated by the configuration information of the measurement reference signal, for example, two or more sets of measurement configuration information are configured for the measurement reference signal, where the measurement period of each set of measurement configuration information is different, and when the terminal device meets the first criterion or enters a measurement relaxed state, the network device may indicate to the terminal device to use different reference signal measurement configurations. For example, the network device may configure two sets of SMTC (SS/PBCH block measurement timing configuration, SSB measurement timing configuration) configurations for the terminal device, where the first SMTC configuration is used when measurement is not relaxed, and the second SMTC configuration is used when measurement is relaxed. Similarly, the network device may also configure similar measurement configuration information for the CSI-RS signal.

With reference to the second aspect, in certain implementations of the second aspect, the first determining to determine whether a relationship between the measurement value of the reference signal of the first reference signal type and the first threshold satisfies a first criterion includes: the first decision is for deciding that a relation between a measurement value of a reference signal of the first reference signal type and a first threshold satisfies a first criterion, or,

Optionally, the first time is greater than or equal to the second time.

With reference to the second aspect, in some implementation manners of the second aspect, the second indication information sent by the terminal device and received by the network device may simultaneously report the measurement result of the terminal device for n times of measurements on the serving cell in one sending and reporting process, and may also simultaneously report the measurement result of the terminal device for m measurements on the neighboring cells.

After receiving the measurement result, the network device can evaluate the approximate position and mobility information of the terminal device, and further judge whether to enable the terminal device to perform connection state measurement relaxation, so that the network device can indicate according to the communication state of the terminal device, and the controllability of the network device is realized.

Fig. 2 is an example of a communication method according to an embodiment of the present application, and as shown in the figure, the method 200 includes:

s210, the network equipment sends first indication information to the terminal equipment.

Specifically, the first indication information is used for indicating a first reference signal type. Further, the first indication information is used for indicating the terminal device to make a first decision on the reference signal of the first reference signal type, and the first decision is used for deciding whether the relation between the measurement value of the reference signal of the first reference signal type and the first threshold value meets a first criterion. Optionally, the first indication information is further used to indicate a first threshold, or offset information. It should be noted that, if the first indication information is used to indicate the offset information, it is possible that the terminal device has received the threshold information once in the idle state or the inactive state, and the terminal device combines the offset information on the basis of the threshold information for subsequent determination. 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 of the terminal device in an idle state, and the terminal device defaults to use the threshold in the idle state for continuous determination.

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

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 may measure the SSB signal and the terminal device may also measure the CSI-RS signal.

In some embodiments, the network device sends first indication information to the terminal device, the first indication information indicating a first reference signal type. Optionally, the network device may also separately send, in information other than the first indication information, the first threshold information to the terminal device, where the first threshold information is used to indicate a first threshold corresponding to the first reference signal type indicated by the first indication information. 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 a connected state, the terminal device receives first indication information sent by the network device, where the first indication information indicates that the first reference signal type is an SSB signal, and if the terminal device does not receive the first threshold information, the terminal device defaults to use a threshold corresponding to the SSB signal in an idle state; for another example, in a connected state, the terminal device receives first indication information sent by the network device, where the first indication information indicates that the first reference signal type is an SSB signal, and the terminal device also receives first threshold information sent by the network device, and then the terminal device uses a first threshold indicated by the first threshold information to determine whether a measurement value measured by using the SSB signal satisfies a first criterion; for another example, in a connected state, the terminal device receives first indication information sent by the network device, where the first indication information indicates that the first reference signal type is a CSI-RS signal, and the terminal device also receives first threshold information sent by the network device, and then the terminal device uses a first threshold indicated by the first threshold information to determine whether a measurement value measured by using the CSI-RS signal satisfies a 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 first indication message to the terminal device, where the first indication message is used to indicate a reference signal type and a threshold corresponding to the reference signal type. In a possible implementation manner, a plurality of fields are predefined, each field corresponds to one reference signal type, each field corresponds to one piece of first indication information, and the value of the field is the threshold value of the corresponding reference signal type. For example, two fields, field a and field B, are predefined, field a corresponds to an SSB signal, field B corresponds to a CSI-RS signal, when the terminal device receives a first indication information, where the first indication information is located in field a, the first indication information is used to indicate that measurement is performed using the SSB signal, the value of field a is a threshold value corresponding to the SSB signal, and the terminal device uses the threshold value corresponding to field a to determine whether a measurement value measured using the SSB signal satisfies a first criterion.

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

In some embodiments, when the terminal device is in a connected state, the first indication information may be separately sent through a broadcast or a dedicated signaling, where the dedicated signaling may be a Radio Resource Control (RRC) reconfiguration message or a Medium Access Control (MAC) Control Element (CE) MAC CE, and the like, and this is 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 defined in the reporting list in an event that triggers reporting or reports periodically based on an event. 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 all of the measurement configuration information received by the terminal device in the connected state indicates that the terminal device performs measurement or reporting using an SSB signal, the terminal device does not receive the first indication information but defaults to perform measurement for the first decision using the SSB signal, or when all of the measurement configuration information received by the terminal device in the connected state indicates that the terminal device performs measurement or reporting using a CSI-RS signal, the terminal device does not receive the first indication information but defaults to perform measurement for the first decision using a CSI-RS signal.

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

It should be noted that, if the first indication information is received, the measurement of the first decision is not performed by using the default SSB signal, and correspondingly, the measurement of the first decision is performed on the reference signal of the type according to the first reference signal type indicated by the first indication information. For another example, 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, and 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 static criterion, a non-cell-edge criterion. It should be noted that the inactivity criterion and the out-of-cell-edge criterion may evaluate the approximate location and mobility information of the terminal device to some extent.

Specifically, if the relationship between the first measurement value and the first threshold (or the offset of the first threshold) satisfies the stationarity criterion, the relationship between the first measurement value and the first threshold of the reference signal of the first reference signal type satisfies the following relationship:

for a first reference signal type of SSB signal:

(Srxlev _Ref –Srxlev)<S _SearchDeltaP wherein S is _SearchDeltaP Is a first threshold corresponding to the SSB signal, i.e., the threshold evaluation criterion is used when the SSB signal is used for measurements. Srxlev is Reference Signal Receiving Power (RSRP) quality of the current serving cell, i.e. a first measurement value, srxlev _Ref Is the reference RSRP quality of the current serving cell.

Optionally, after the relationship between the first measurement value measured by the terminal device and the first threshold satisfies the above formula or the maintenance time of the stationary criterion is greater than or equal to the first time, the terminal device determines that the relationship between the first measurement value of the SSB signal and the first threshold satisfies the stationary 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 application.

It should be noted that the first time may be a maintenance time that the network device configures to the terminal device and satisfies the inactivity criterion.

It should be noted that the first time may be a time configured by the network device to the terminal device in the idle state. The first time may also be a time configured to the terminal device by the network device in the connected state. It should be noted that the first time at which the idle-state network device and the connected-state network device are configured to the terminal device 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 indicates that the terminal device uses 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 may also configure, to the terminal device, a second time of the maintaining time that does not meet the static criterion, where the second time is used for the terminal device to determine whether to leave the measurement relaxed state, and a specific name of the second time may be Tout, which is not limited in this application. The second time will be described in the following, and will not be described herein again.

It should be noted that the first time may be longer than the second time, so that the terminal device may leave the measurement relaxed state more quickly, and the performance of the terminal device in the connection state is ensured. Optionally, the first time may also be equal to the second time, and the first time may also be less than the second time, which is not limited in this embodiment of the application.

Optionally, the first time of the holding time satisfying the inactivity criterion and the second time of the holding time not satisfying the inactivity criterion may be configured through an RRC message. Optionally, the first time of the maintenance time meeting the inactivity criterion and the second time of the maintenance time not meeting the inactivity criterion may be configured by a reporting configuration in the measurement configuration, that is, the network device may send configuration information of the first time and the second time to the terminal device at the same time, and specifically, one way for the network device to configure the first time and the second time to the terminal device at the same time may be that the first time and the second time are two trigger times of one measurement event.

Optionally, if the relationship between the measurement value and the first threshold does not meet the first criterion within the third time, the terminal device sets Srxlev of the camped cell or the serving cell to Srxlev _Ref . Optionally, the third time is indicated to the terminal device by the network device. Optionally, the third time is default for the terminal device. The third time may be the same as the first time or the second time. It should be noted that, for configurations with similar retention time that are not in the cell edge criterion, reference may be made to the configuration of the retention time of the above-mentioned static criterion, and details of the embodiments of the present application are not described herein again.

For a first reference signal type being a CSI-RS signal:

(Srxlev _Ref –Srxlev)<S _{SearchDeltaPCSI} in the alternative, the first and second pluralities of fibers may be,

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

Specifically, if the relationship between the first measurement value and the first threshold (or the offset of the first threshold) satisfies the criterion of not being at the cell edge, the relationship between the first measurement value and the first threshold satisfies the following relationship:

for a first reference signal type of SSB signal:

Srxlev>S _{searchThresholdP} and,

Wherein S is _{SearchThresholdP} And S _{SearchThresholdQ} The threshold received for the idle or inactive state, which in some embodiments is the threshold, offset, of the SSB signal _CSI To be connected atOffset received in state, S _{SearchDeltaPCSI} 、S _{SearchThresholdQCSI} The first threshold value is indicated by the first indication information received in the connection state. Wherein the threshold value received in the idle state is the threshold value broadcasted in the system message.

It should be noted that, in some embodiments, the terminal device performs the first determination according to the threshold of the broadcasted SSB signal in the idle state, when the terminal device enters the connected state from the idle state, the network device may indicate that the type of the reference signal measured by the terminal device is an SSB signal or a CSI-RS signal, when the signal measured is an SSB signal, the threshold of the SSB signal in the idle state may be used, or the first threshold of the SSB signal may be re-indicated, and when the signal measured is a CSI-RS signal, the offset may be indicated on the basis of 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 this application.

It should be noted that, in some cases, the network device may also instruct the terminal device to measure whether other criteria are met, which is not limited in this application. Optionally, the other criteria may assist the network device in determining whether to cause the terminal device to enter a measurement relaxed state.

S220, the terminal device measures the reference signal of the first reference signal type according to the first indication information in the connection state to obtain a first measurement value.

Specifically, the terminal device receives the first indication information, determines a first reference signal type for making the first determination, and 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 in terms of time of the measurements, and n is greater than or equal to 1.

The terminal device may measure m neighbor 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 a relationship between the first measurement value and the first threshold satisfies a first criterion.

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

In some embodiments, the second indication information is included in a measurement report sent by the terminal device to the network device. Optionally, the terminal device may perform n times of measurement on the serving cell, and report the measurement result satisfying the first criterion, where the n times of measurement may be sorted according to the measurement time, and optionally, the terminal device may also perform measurement on m neighboring cells, and report the measurement result satisfying the first criterion.

In some embodiments, the terminal device reports the measurement results of n serving cells, where the measurement results of the n serving cells may be n results meeting a criterion, or after the criterion is met, the reported n measurement results include measurement results that do not meet the criterion.

In some embodiments, the terminal device reports m neighbor cell measurement results when the first criterion is satisfied. Reporting the result can enable the network device to acquire more information of the terminal device to judge whether the terminal is permitted to perform measurement relaxation.

S240, the network device sends third indication information to the terminal device, and the third indication information is used for indicating the terminal device to enter a measurement relaxation state.

It should be noted that this step is optional, and if the network device determines that the terminal device cannot enter the measurement relaxed 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 result of the serving cell in the second indication information, and optionally, the network device judges whether the terminal device may be switched according to the measurement result of the neighboring cell in the second indication information.

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

It is to be understood that the content of the measurement relaxation may be a frequency measurement relaxation, a cell measurement relaxation, a periodic measurement relaxation, etc. Specifically, the third indication information may include: the frequency to be measured, or the frequency to be measured to be relaxed, or the cell to be measured to be relaxed, or the period of the measurement (e.g., the period is seconds, minutes, hours, etc.). In other words, after the terminal device enters the measurement relaxation state, the measurement relaxation may be performed on the period, and the network device may instruct the terminal device to measure the period relaxation, by way of example and not limitation, the original measurement period may be measured every 5 minutes, and after the terminal device enters the measurement relaxation state, the measurement period may be measured every 10 minutes. After the terminal device enters the measurement relaxation state, measurement relaxation may be performed on a certain frequency, and by way of example and not limitation, the terminal device may not perform measurement on the frequency. After the terminal device enters the measurement relaxation state, measurement relaxation may be performed on a certain cell, and as an example and not by way of limitation, the terminal device may not perform measurement on the cell.

It should be noted that, the content of the terminal device entering the measurement relaxation state may also be a combination of the above three, by way of example and not limitation, the network device may instruct the terminal device to measure once every 20 minutes for a certain cell a, and once every 10 minutes for a certain cell B, where the content of the measurement relaxation may be specifically indicated by the third indication information of the network device, or may instruct the terminal device to enter the measurement relaxation state by default, and the terminal device side measures the relaxed content. The third indication information may be an RRC reconfiguration message.

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

In some embodiments, the third indication information may carry a measurement ID, a measurement object ID, and the like, for indicating to relax the measurement object corresponding to the ID. It may also indicate which reference signal to measure relaxed.

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

The embodiment of the present application takes the stationary criterion as an example to describe the first condition that the terminal device leaves the measurement relaxed state. It should be understood that, a similar first condition for the terminal device to determine to leave the measurement relaxed state may also exist without the cell edge criterion, which is not described in detail in this embodiment of the present application, but this 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 formula for the stationary criterion, and the holding time of the stationary criterion formula reaches the preset time for the second time, that is, the relationship between the first measurement value and the first threshold does not satisfy the formula for the stationary criterion within the second time, or the relationship between the first measurement value and the first threshold does not satisfy the formula for the stationary criterion during the second time. Specifically, the second time value may be 0. The leaving conditions for the static criteria will be described in method 400 and will not be described in detail herein.

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 indicates that the terminal device leaves the measurement relaxed state.

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

In a possible implementation manner, taking the inactivity criterion as an example, the first condition may be that the terminal device multiplexes triggering conditions of some events, for example, triggering conditions of measurement reporting events defined in 3GPP protocols such as A3, A4, A5, and the like. Events A3, A4, A5, etc. will be briefly described below.

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

Mn+Ofn+Ocn–Hys>Mp+Ofp+Ocp+Off

the leaving condition A3-2 of the A3 event satisfies the formula:

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

the method comprises the steps of obtaining a cell specific offset value of a serving cell, obtaining a cell specific offset value of the serving cell, obtaining Mn as a cell measurement result of a neighboring cell, obtaining Ofn as a specific offset value obtained by measuring a reference signal of the neighboring cell, obtaining Ocn as a cell specific offset value of the neighboring cell, obtaining Mp as a measurement result of the serving cell, obtaining Ofp as a measurement object specific offset value of the serving cell, obtaining Ocp as a cell specific offset value of the serving cell, obtaining Hys as a hysteresis quantity and obtaining Off as an offset value of an event.

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

Mn+Ofn+Ocn–Hys>Thresh

the leaving condition A4-2 of the A4 event satisfies the formula:

Mn+Ofn+Ocn+Hys<Thresh

where Thresh is the threshold for the A4 event. The 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 leaving condition A5-2 of the A5 event satisfies the formula:

Mp-Hys > Thresh1, or

Mn+Ofn+Ocn+Hys<Thresh2

Where Thresh1 and Thresh2 are the threshold values for the event, and the other definitions are the same as above.

It should be noted that the events such as A3, A4, and A5 may be measurement events used for switching configuration, or measurement events applicable to other situations, which is not limited in the 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 may determine to leave the measurement relaxed state. Optionally, the measurement result may not satisfy a trigger time configuration (timeout) configured by the network device in the A3 event, that is, only the formula condition in the A3 event is multiplexed, and the trigger time in the A3 event is not multiplexed. Alternatively, the terminal device measurement result may only satisfy the formula condition of the A3 event, and the time that does not satisfy the stationary criterion or satisfies the leaving condition of the stationary criterion, i.e. Tout or the second time, the cell quality measured by the terminal device may be used at the trigger time, and the measurement relaxation may be stopped when the formula defined by the A3 event is satisfied within the second time. Optionally, the measurement result may also satisfy a 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 relaxed state after triggering some event reports.

Taking the event A3 as an example, when the terminal device triggers the event A3 to report, the measurement relaxed state is terminated by default.

It should be understood that the terminal device may automatically end the measurement relaxed state after the first condition is reached, and the terminal device may also send, to the network device, indication information indicating that the network device has reached the first condition. After receiving the indication information, the network device may determine whether to instruct the terminal device to end the measurement in the relaxed state, and when receiving the indication that the network device ends the measurement in the relaxed state, the terminal device ends the measurement in the relaxed state.

According to the technical scheme provided by the embodiment of the application, when the terminal equipment enters the connection state, the type of the first reference signal of the terminal equipment can be indicated, so that the terminal equipment can measure the reference signal of the type of the first reference signal based on the indication, obtain the first measured value, judge whether the relation between the first measured value and the first threshold meets the first criterion or not, report the judgment result to the network equipment by the terminal equipment, indicate whether the terminal equipment enters the measurement relaxation state or not according to the result by the network equipment, and when the terminal equipment enters the measurement relaxation state, the power consumption of the terminal equipment in the connection state can be saved.

Fig. 3 shows another example of the communication method according to the embodiment of the present application. As shown in fig. 3, the method 300 includes:

s310, the network device sends first indication information to the terminal device, wherein the first indication information is used for indicating the type of the first reference signal.

Specifically, the first indication information may be used to indicate that the terminal device needs to perform a first decision on a reference signal of the first reference signal type, where the first decision is that the terminal device needs to decide whether a relationship between a measurement value of the reference signal of the first reference signal type and the first threshold satisfies a first criterion.

In some embodiments, when the terminal device is in a connected state, the network device sends first indication information to the terminal device, where the first indication information may be sent through a broadcast message or may be sent through dedicated signaling, for example, a Radio Resource Control (RRC) reconfiguration message or a Medium Access Control (MAC) Control Element (CE) MAC CE, and the like. 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, and it should be noted that the measurement is used to make the first decision.

In some embodiments, when the terminal device is in a connected state, all of the measurement configuration information received by the terminal device indicates that the terminal device performs measurement or reports using an SSB signal, the terminal device does not receive the first indication information but defaults to perform measurement for the first determination using the SSB signal, or when the terminal device is in a connected state, all of the measurement configuration information received by the terminal device indicates that the terminal device performs measurement or reports using a CSI-RS signal, the terminal device does not receive the first indication information but defaults to perform measurement for the first determination using the CSI-RS signal. 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 for the measurement for the first decision, and the network device is not required to send the first indication information for indicating the type of the first reference signal.

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, and 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 receives the first indication information, that is, performs measurement and determination of the first determination, and does not need to perform configuration by using special measurement configuration information.

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

In a possible implementation manner, when the terminal device is in a connected state, the network device sends first indication information to the terminal device, where the first indication information indicates a first threshold, or the first indication information indicates an offset of the first threshold, and the first threshold, or the first offset is a first threshold or an offset related to the SSB signal, the terminal device defaults to perform measurement for the first decision on the SSB signal, and if the first threshold, or the offset of the first threshold is the first threshold or the offset related to the CSI-RS, the terminal device defaults to perform measurement for the first decision on the CSI-RS signal. In this implementation, the first signal type may not need to be indicated separately.

And S320, the terminal equipment measures the reference signal of the first reference signal type according to the first indication information in the connection state, and acquires a first measurement value.

The terminal device may make at least n measurements of the serving cell, where n is greater than or equal to 1.

The terminal device may measure at least m neighbor cells of the serving cell, where m is greater than or equal to 1.

S330, the terminal equipment determines the result of the first judgment according to the first measurement value and the first threshold value.

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

It should be noted that, the relation that the relationship between the first measurement value and the first threshold value needs to be satisfied when the first criterion is satisfied may be referred to the description of step S210 in the method 200, and details are not described herein.

The network device and the network device S340 send second indication information to the network device, where the second indication information is used to indicate a result of the first determination.

In some embodiments, the terminal device determines that a relationship between the first measurement quantity and the first threshold satisfies a first criterion, and sends second indication information to the network device, where the second indication information is used to indicate that the relationship between the first measurement quantity and the first threshold satisfies the first criterion, optionally, the terminal device may perform n measurements on the serving cell, and report measurement results satisfying the first criterion, where the n measurements may be sorted according to measurement time, and optionally, the terminal device may also perform measurements on m neighboring cells, and report measurement results satisfying the first criterion.

In some embodiments, the terminal device determines that a relationship between the first measurement quantity and the first threshold does not satisfy the first criterion, and sends second indication information to the network device, where the second indication information is used to indicate that the relationship between the first measurement quantity and the first threshold does not satisfy the first criterion, optionally, the terminal device may perform n measurements on the serving cell, and report measurement results that do not satisfy the first criterion, where the n measurements may be sorted according to measurement time, optionally, the terminal device may also perform measurements on m neighboring cells, and report measurement results that do not satisfy the first criterion, where m and n are positive integers.

In some embodiments, the terminal device determines whether a relationship between the first measurement quantity and the first threshold meets a first criterion, and sends second indication information to the network device, where the second indication information is used to indicate whether the relationship between the first measurement quantity and the first threshold meets the first criterion, optionally, the terminal device may perform n measurements on the serving cell and report the n measurement results, optionally, the terminal device may also perform measurements on multiple neighboring cells and report whether the measurement results of m neighboring cells with the best cell quality meet the first criterion, where m and n are positive integers.

The second indication information may be transmitted to the network device through the terminal device assistance information message, or may be transmitted to the network device through the MAC CE information.

It should be noted that, after the terminal device sends the second indication information to the network device, and does not receive the third indication information sent by the network device, the terminal device may wait for sending the second indication information again after a first time, where the first time may be sent to the terminal device by the network device before, or may be default or preconfigured or protocol-specified by the terminal device. Optionally, after the terminal device reports for L times and still does not receive the third indication information of the network device, the terminal device stops sending the second indication information to the network device, where the size of L may be sent to the terminal device by the network device before, or may be default for the terminal device, and after the terminal device stops sending the second indication information, if the terminal device receives the first indication information again, the terminal device measures again and sends the second indication information according to the determination result.

Optionally, before the terminal device reports the indication information, the network device may configure, to the terminal device, the maximum number L of times that is reported after meeting the first criterion, and when the terminal device meets the first criterion, start to send the second indication information to the network device, where the sending period is the configuration configured by the network device or the default configuration of the terminal device. Specifically, if the relaxation instruction information is received in the configuration sending process, the terminal device stops sending the second instruction information, and starts to measure relaxation. The L 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, if the terminal device does not receive the third indication information sent by the network device, the terminal device may start the timer, and after the timer expires, it may determine whether the first criterion is met again, if so, the terminal device sends the second indication information again, and if not, the terminal device does not need to send the second indication information. The timer may be sent to the terminal device by the network device before or may be specified by the protocol.

Optionally, after the terminal device determines that the first criterion is satisfied, it may determine whether to perform measurement relaxation by itself without notifying the network device. Or after deciding whether to perform measurement relaxation, sending second indication information to the network equipment, and determining whether the measurement relaxation is performed.

And S350, the network equipment sends third indication information to the terminal equipment, wherein the third indication information is used for indicating the terminal equipment to enter a measurement relaxation state.

It should be noted that this step is optional, and if the network device determines, according to the second indication information, that the terminal device cannot enter the measurement relaxed state, 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 position and mobility information of the terminal device according to the measurement result of the serving cell in the second indication information, and optionally, the network device judges whether the terminal device may be switched according to the measurement result of the neighboring cell in the second indication information.

It is to be understood that the content of the measurement relaxation may be a frequency measurement relaxation, a cell measurement relaxation, a periodic measurement relaxation, etc. In other words, after the terminal device enters the measurement relaxed state, the period may be measured relaxed, and the network device may instruct the terminal device to measure the period relaxed, by way of example and not limitation, the original measurement period may be measured every 5 minutes, and after entering the measurement relaxed state, the measurement period may be measured every 10 minutes. After the terminal device enters the measurement relaxed state, measurement may be relaxed for a certain frequency, which may not be measured by the terminal device by way of example and not limitation. After the terminal device enters the measurement relaxation state, measurement relaxation may be performed on a certain cell, and as an example and not by way of limitation, the terminal device may not perform measurement on the cell.

It should be noted that, the content of the terminal device entering the measurement relaxation state may also be a combination of the above three, by way of example and not limitation, the network device may instruct the terminal device to measure once every 20 minutes for a certain cell a, and once every 10 minutes for a certain cell B, where the content of the measurement relaxation may be specifically indicated by the third indication information of the network device, or may instruct the terminal device to enter the measurement relaxation state by default, and the terminal device side measures the relaxed content.

Optionally, the terminal device uses the SSB signal to perform measurement or uses the CSI-RS signal to perform measurement, and receives the third indication information, and may perform measurement relaxation on the relevant 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 the relevant 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 the relevant measurement corresponding to the CSI-RS signal.

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

It should be understood that the network device sending the third indication information to indicate that the measurement is relaxed for the period may specifically indicate in the form that the network device sends the 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, that is, the first SMTC configuration and the second SMTC configuration, to the terminal device. The first SMTC configuration may be used when the terminal device does not enter a 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 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, and 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 slot, subframe, symbol, etc. 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 is configured as the first SMTC configuration or the second SMTC configuration.

Alternatively, the second SMTC configuration may be indicated by a dedicated field, if present, the terminal device being configured with configuration information for relaxed use of measurements that meets the first criterion, which field may be in the measurement object configuration of the measurement configuration.

It should be noted that, the second SMTC configuration may be configured synchronously with the configuration message of the first criterion when the terminal device does not satisfy the first criterion; the second SMTC configuration may be reconfigured when the terminal device meets the first criterion. Optionally, when the terminal device meets the first criterion, the network device may send indication information to the terminal device, where the indication information indicates that the terminal device uses the second SMTC configuration for measurement. It should be understood that the indication information may be equivalent to the third indication information, that is, the network device implicitly instructs the terminal device to enter the measurement relaxed state and perform measurement using the second SMTC configuration when sending the measurement using the second SMTC configuration to the terminal device. If the second SMTC configuration has not been configured for the terminal device before, the second SMTC configuration may be included in the indication information, and if so, after receiving the indication information, the terminal device performs relaxation measurement using the second SMTC configuration.

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

Optionally, the network device may also only configure the first SMTC configuration for the terminal device, and after 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 changes, for example, the network device may indicate that the measurement period in the first SMTC configuration of the terminal device is set to be x times of the original measurement period, or, default in a protocol, when the terminal device is in the measurement relaxation state, the used period is x times of the period when the terminal device is not in the measurement relaxation state, and after the terminal device enters the measurement relaxation state or receives the third indication message, the measurement is performed by applying the period corresponding to the measurement relaxation state, and in some embodiments, x may be equal to 2. It should be noted that the target for measurement relaxation may be for the serving cell or for the neighboring cell.

Similarly, the network device may also configure the CSI-RS signal with similar configuration information.

Specifically, the network device sends CSI-RS configuration information for configuring CSI-RS resources to the terminal device, where the CSI-RS configuration information includes information such as cell identifiers and frequency domain configurations, and also includes at least one CSI-RS resource configuration set.

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, periodicity, and offset. Similar to the SMTC resource configuration, the CSI-RS resource configuration set may include a first CSI-RS configuration and a second CSI-RS configuration, where the first CSI-RS configuration is used by the terminal device when not measuring the relaxed state, and the second CSI-RS configuration is used by the terminal device when measuring the relaxed state. It should be noted that the protocol predefines that a first CSI-RS configuration is configured in the a field, and a second CSI-RS configuration is configured in the B field. The configuration of the a field is the first CSI-RS configuration by default and the configuration of the B field 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 configure the first CSI-RS configuration first 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 relaxation state, or the network device may configure the first CSI-RS configuration first when the terminal device does not enter the measurement relaxation state, and indicate that a period in the first CSI-RS configuration is changed to X times of the original period when the terminal device enters the measurement relaxation state, for example, X =2, and specific description may refer to configuration of the SMTC, which is not described herein.

And S360, the terminal equipment finishes measuring the relaxation state.

In some embodiments, the communication apparatus 600 may be the terminal device in the above method embodiment 200, or may be a chip for implementing the functions of the terminal device in the above method embodiment. It should be understood that the communication apparatus 600 may correspond to the steps corresponding to the terminal device in the method 200 of the embodiment of the present application. The communication device 600 includes:

the transceiving unit 610 is configured to receive first indication information sent by a network device.

The processing unit 620 is configured to measure a reference signal of a first reference signal type according to the first indication information in the connected state to obtain a first measurement value.

Specifically, the first indication information is used for indicating a first reference signal type. Further, the first indication information is used to instruct the processing unit 620 to make a first decision on the reference signal of the first reference signal type, the first decision being used to decide whether a relation between a measured value of the reference signal of the first reference signal type and the first threshold satisfies a first criterion. Optionally, the first indication information is further used to indicate a first threshold, or offset information. It should be noted that, if the first indication information is used to indicate the offset information, the transceiver unit 610 may have received the threshold information once in the idle state or the inactive state, and the processing unit 620 combines the offset information for subsequent determination based on the threshold information. Optionally, the first threshold may be a reconfigured first threshold when the communication apparatus enters the connected state, optionally, the first threshold may be a threshold when the communication apparatus is in an idle state, and the processing unit 620 uses the threshold in the idle state by default to continue to be used for the determination.

Specifically, the first Reference Signal type may include a Synchronization Signal Block (SSB), a Channel State Information-Reference Signal (CSI-RS). It should be noted that when the communication apparatus is in the idle state or the inactive state, the terminal device may be configured with the SSB signal, and when the communication apparatus is in the connected state, the processing unit 620 may be configured with the SSB signal and/or the CSI-RS signal.

It should be noted that, in an idle state or an inactive state, processing unit 620 may measure an SSB signal, and in a connected state, processing unit 620 may measure an SSB signal, and processing unit 620 may also measure a CSI-RS signal.

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 communication apparatus is in a connected state, all of the measurement configuration information received by the transceiving unit 610 indicates that the processing unit 620 performs measurement or reports using an SSB signal, the transceiving unit 610 does not receive the first indication information but performs measurement for the first determination by default using the SSB signal, or when all of the measurement configuration information received by the transceiving unit 610 indicates that the processing unit 620 performs measurement or reports using a CSI-RS signal, and when the communication apparatus is in a connected state, the transceiving unit 610 does not receive the first indication information but the processing unit 620 performs measurement for the first determination by default using the CSI-RS signal. It should be noted that other aspects of measurement requirements are configured in the measurement configuration information. For another example, when the communication apparatus is in the connected state, the SSB signal is used by default to perform the measurement for the first determination, and the network device is not required to send the first indication information to perform the indication of the first reference signal type. It should be noted that, if the first indication information is received, the measurement of the first decision is not performed by using the default SSB signal, and correspondingly, the measurement of the first decision is performed on the reference signal of the type according to the first reference signal type indicated by the first indication information. For another example, when the communication apparatus is in an idle state or an inactive state, the network device broadcasts first indication information to the transceiver unit 610, optionally, the first reference signal type indicated by the first indication information is an SSB signal, and optionally, the first reference signal type indicated by the first indication information is a CSI-RS signal.

It should be noted that, in some embodiments, the communication apparatus performs the first determination according to the threshold of the broadcasted SSB signal in the idle state, when the communication apparatus enters the connected state from the idle state, the network device may instruct the processing unit 620 to measure the type of the reference signal as an SSB signal or a CSI-RS signal, and when the measured signal is an SSB signal, may delay the threshold of the SSB signal in the idle state, or may re-instruct the first threshold of the SSB signal, and when the measured signal is a CSI-RS signal, may instruct the offset amount based on the threshold of the SSB signal in the idle state, or re-instruct the first threshold of the CSI-RS signal, which is not particularly limited in this application.

It should be noted that, in some cases, the network device may also instruct the processing unit 620 to measure whether other criteria are met, which is not limited in this application. Optionally, the other criteria may assist the network device in determining whether to cause the communication device to enter a measurement relaxed state.

The transceiving unit 610 is further configured to send second indication information to the network device, where the second indication information is used to indicate that a 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, and may be sent to the network device through the auxiliary information message of the transceiving unit 610, or may be sent to the network device through the MAC CE information. The second indication information is used to indicate that a relationship between the first measurement value and the first threshold satisfies a first criterion, optionally, the processing unit 620 may perform at least n measurements on the serving cell, and report a measurement result satisfying the first criterion, where the n measurements may be sorted according to measurement time, and optionally, the processing unit 620 may also perform measurements on m neighboring cells, and report a measurement result satisfying the first criterion.

In some embodiments, the second indication information is included in a measurement report sent to the network device by the processing unit 620. Optionally, the processing unit 620 may perform at least n times of measurement on the serving cell, and report the measurement result satisfying the first criterion, where the n times of measurement may be sequenced according to the measurement time, and optionally, the processing unit 620 may also perform measurement on m neighboring cells, and report the measurement result satisfying the first criterion.

Specifically, the first indication information is used for indicating a first reference signal type. Further, the first indication information is used for indicating the terminal device to make a first decision on the reference signal of the first reference signal type, and the first decision is used for deciding whether the relation between the measurement value of the reference signal of the first reference signal type and the first threshold value meets a first criterion. Optionally, the first indication information is further used to indicate a first threshold, or offset information. It should be noted that, if the first indication information is used to indicate the offset information, it is possible that the terminal device has already received the threshold information once in the idle state or the inactive state, and the terminal device combines the offset information for subsequent determination on the basis of the threshold information. Optionally, the first threshold may be a first threshold reconfigured when the terminal device enters the connected state, and optionally, the first threshold may be a threshold of the terminal device in the idle state, and the terminal device defaults to continuously use the threshold in the idle state for determination.

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, and the content indicated by the first indication information may be defined in the reporting list in an event that triggers reporting or reports periodically based on an event. 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 all of the measurement configuration information received by the terminal device in the connected state indicates that the terminal device performs measurement or reporting using an SSB signal, the terminal device does not receive the first indication information but defaults to perform measurement for the first decision using the SSB signal, or when all of the measurement configuration information received by the terminal device in the connected state indicates that the terminal device performs measurement or reporting using a CSI-RS signal, the terminal device does not receive the first indication information but defaults to perform measurement for the first decision using a CSI-RS signal. It should be noted that other measurement requirements are configured in the measurement configuration information. For another example, when the terminal device is in a connected state, the SSB signal is used by default for performing measurement for the first determination, and the network device is not required to send the first indication information for indicating the type of the first reference signal. It should be noted that, if the first indication information is received, the measurement of the first decision is not performed by using the default SSB signal, and correspondingly, the measurement of the first decision is performed on the reference signal of the type according to the first reference signal type indicated by the first indication information. For another example, 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, and optionally, the first reference signal type indicated by the first indication information is a CSI-RS signal. Correspondingly, when the terminal device enters the connection 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.

for a first reference signal type of SSB signal:

(Srxlev _Ref –Srxlev)<S _SearchDeltaP wherein S is _SearchDeltaP Is a first threshold corresponding to the SSB Signal, and Srxlev is a Reference Signal Receiving Power (RSRP) quality of the current serving cell, i.e., a first measurement value, srxlev _Ref Is the reference RSRP quality of the current serving cell.

Specifically, the names of the threshold and the offset in the embodiment of the present application only represent an example of one name, and other names may also be used, which is not limited in the embodiment of the present application.

Srxlev>S _{searchThresholdP} and,

For a first reference signal type being a CSI-RS signal:

Srxlev>S _{SearchThresholdP} +offset _CSI and, in addition,

Or,

Srxlev>S _{SearchThresholdPCSI} and, in addition,

It should be noted that, in some embodiments, the terminal device performs the first determination according to the threshold of the broadcasted SSB signal in the idle state, when the terminal device enters the connected state from the idle state, the network device may indicate that the type of the reference signal measured by the terminal device is an SSB signal or a CSI-RS signal, when the signal measured is an SSB signal, the threshold of the SSB signal in the idle state may be used, or the first threshold of the SSB signal may be re-indicated, and when the signal measured is a CSI-RS signal, the offset may be indicated on the basis of 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 this application. It should be noted that, in some cases, the network device may also instruct the terminal device to measure whether other criteria are met, which is not limited in this application. Optionally, the other criteria may assist the network device in determining whether to cause the terminal device to enter a measurement relaxed state.

The transceiver unit 610 is further configured to receive second indication information sent by the terminal device, where the second indication information is used to indicate that a 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 transceiving unit 610 as a separate signaling, and may be sent to the transceiving unit 610 through a terminal equipment assistance information message, or may be sent to the transceiving unit 610 through MAC CE information. The second indication information is used to indicate that a relationship between the first measurement value and the first threshold satisfies a first criterion, optionally, the terminal device may perform at least n measurements on the serving cell, and report a measurement result satisfying the first criterion, where the n measurements may be sorted according to measurement time, and optionally, the terminal device may also perform measurements on m neighboring cells, and report a measurement result satisfying the first criterion.

In some embodiments, the terminal device reports the measurement results of n serving cells, where the measurement results of the n serving cells may be n results that satisfy a criterion, or after the criterion is satisfied, the n reported measurement results include measurement results that do not satisfy the criterion.

In some embodiments, after meeting the first criterion, the terminal device reports m neighbor cell measurement results. Reporting the result can enable the network device to acquire more information of the terminal device to judge whether the terminal is permitted to perform measurement relaxation.

In some embodiments, the second indication information is included in a measurement report of the terminal device sent to the transceiving unit 610. Optionally, the terminal device may perform n times of measurement on the serving cell, and report the measurement result satisfying the first criterion, where the n times of measurement may be sorted according to the measurement time, and optionally, the terminal device may also perform measurement on m neighboring cells, and report the measurement result satisfying the first criterion.

In some embodiments, the terminal device may also report measurements that do not meet the first criterion.

In another embodiment, for the idle-state static criterion or the non-cell-edge criterion, the connected-state terminal may also use or reuse the criterion. Specifically, when the base station sends the system message, the base station may send an indication message for indicating whether the terminal uses the idle-state configuration criterion or parameter to evaluate whether the terminal meets the static criterion after entering the connected state, and may perform a subsequent reporting procedure.

In another mode, the base station sends indication information to the terminal in message 4 or RRC reconfiguration to indicate whether to use the in-broadcast inactivity criterion.

If the requirement is met, reporting the measurement information in the UE auxiliary information or reporting the measurement information in a measurement report.

The transceiving unit 610 is further configured to send third indication information to the terminal device, where the third indication information is used to indicate that the terminal device enters a measurement relaxed state.

It should be noted that this step is optional, and if the processing unit 620 determines that the terminal device cannot enter the measurement relaxed state according to the second indication information, the network device may not send the third indication information to the terminal device.

Specifically, the transceiver unit 610 receives the second indication information, optionally, the processing unit 620 evaluates an approximate location and mobility information of the terminal device according to a measurement result of the serving cell in the second indication information, and optionally, the processing unit 620 determines whether the terminal device may be handed over according to a measurement result of the neighboring cell in the second indication information.

Specifically, when determining that the terminal device can perform measurement relaxation according to the second indication information, the processing unit 620 sends third indication information to the terminal device, where the third indication information is used to indicate that the terminal device enters a measurement relaxation state. The third indication information may be an RRC message, for example, an RRC reconfiguration message, or a MAC CE message.

It is to be understood that the content of the measurement relaxation may be a frequency measurement relaxation, a cell measurement relaxation, a periodic measurement relaxation, etc. Specifically, the third indication information may include: the frequency to be measured, or the frequency to be measured for relaxation, or the cell to be measured, or the period to be measured (e.g., the period is seconds, minutes, hours, etc.). In other words, after the terminal device enters the measurement relaxation state, the measurement relaxation may be performed on the period, and the processing unit 620 may instruct the terminal device to measure the period relaxation, by way of example and not limitation, the original measurement period is measured every 5 minutes, and after entering the measurement relaxation state, the measurement period may be measured every 10 minutes. After the terminal device enters the measurement relaxation state, measurement relaxation may be performed on a certain frequency, and by way of example and not limitation, the terminal device may not perform measurement on the frequency. After the terminal device enters the measurement relaxation state, measurement relaxation may be performed on a certain cell, and as an example and not by way of limitation, the terminal device may not perform measurement on the cell. It should be noted that, the content of the terminal device entering the measurement relaxed state may also be a combination of the above three, by way of example and not limitation, the network device may instruct the terminal device to measure once every 20 minutes for a certain cell a, and once every 10 minutes for a certain cell B, where the content of the measurement relaxed state may be specifically indicated by the third indication information of the processing unit 620, or may instruct the terminal device to enter the measurement relaxed state by default. The third indication information may be an RRC reconfiguration message.

In some embodiments, the third indication information may carry a measurement ID, a measurement object ID, and the like, and is used to indicate that the measurement object corresponding to the ID is returned. It may also indicate which reference signal to measure relaxed.

In some embodiments, the communication apparatus 600 may be the terminal device in the foregoing method embodiment 300, and may also be a chip for implementing the function of the terminal device in the foregoing method embodiment. It should be understood that the communication apparatus 600 may correspond to the steps corresponding to the terminal device in the method 300 of the embodiment of the present application. The communication device 600 includes:

The processing unit 620 measures the reference signal of the first reference signal type according to the first indication information in the connection state, and obtains a first measurement value.

Specifically, the first indication information is used for indicating a first reference signal type.

Specifically, the first Reference Signal type may include a Synchronization Signal Block (SSB), a Channel State Information-Reference Signal (CSI-RS). It should be noted that when the communication apparatus is in the idle state or the inactive state, the processing unit 620 may be configured with the SSB signal, and when the communication apparatus is in the connected state, the processing unit 620 may be configured with the SSB signal and/or the CSI-RS signal.

Specifically, the first indication information may be used to indicate that the processing unit 620 needs to make a first decision on the reference signal of the first reference signal type, where the first decision is that the processing unit 620 needs to decide whether a relationship between a measurement value of the reference signal of the first reference signal type and the first threshold satisfies a first criterion.

In some embodiments, when the communication apparatus is in a connected state, the network device sends, to the transceiver unit 610, first indication information, where the first indication information may be sent through a broadcast message or through dedicated signaling, for example, a Radio Resource Control (RRC) reconfiguration message, or a Media Access Control (MAC) Control Element (Control Element, CE) MAC CE, and the like, which is not limited in this embodiment of the present application. The first indication information is used to instruct the processing unit 620 to perform measurement on the SSB signal, or to perform measurement on the CSI-RS signal, or to perform measurement on other possible types of reference signals, it should be noted that the measurement is used to perform the first decision.

In some embodiments, when the communication apparatus is in a connected state, all of the measurement configuration information received by the transceiver unit 610 indicates that the processing unit 620 performs measurement or reporting using the SSB signal, and the transceiver unit 610 does not receive the first indication information, but the processing unit 620 performs measurement for the first determination by default using the SSB signal, or when all of the measurement configuration information received by the transceiver unit 610 indicates that the processing unit 620 performs measurement or reporting using the CSI-RS signal, and the transceiver unit 610 does not receive the first indication information but the processing unit 620 performs measurement for the first determination by default using the CSI-RS signal. It should be noted that other measurement requirements are configured in the measurement configuration information.

In some embodiments, the communication device, when in the connected state, defaults to using the SSB signal for the measurement for the first decision without the network device sending the first indication information for the indication of the first reference signal type.

In some embodiments, when the communication apparatus is in an idle state or an inactive state, the network device broadcasts, to the transceiver unit 610, first indication information, optionally, the first reference signal type indicated by the first indication information is an SSB signal, and optionally, the first reference signal type indicated by the first indication information is a CSI-RS signal. Correspondingly, when the communication 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 protocol on the communication device side is adaptively modified, so that the transceiver unit 610 receives the first indication information, i.e., performs measurement and determination of the first determination, without performing configuration by using special measurement configuration information.

It should be understood that the first indication information may also be used to indicate the first threshold, or, the offset information, it should be noted that, if the first indication information is used to indicate the offset information, it may be that the communication apparatus has received the threshold information once in the idle state or the inactive state, and the terminal device combines the offset information on the basis of the threshold information for subsequent determination. Optionally, the first threshold may be a reconfigured first threshold when the communication apparatus enters the connected state, and optionally, the first threshold may be a threshold when the communication apparatus is in the idle state.

In a possible implementation manner, when the communication apparatus is in the connected state, the network device sends, to the transceiving unit 610, first indication information, where the first indication information indicates a first threshold, or the first indication information indicates an offset of the first threshold, and the first threshold, or the first offset is a first threshold or an offset related to the SSB signal, the processing unit 620 defaults to perform measurement for a first decision on the SSB signal, and if the first threshold, or the offset of the first threshold is the first threshold or the offset related to the CSI-RS, the processing unit 620 defaults to perform measurement for the first decision on the CSI-RS signal. In this implementation, the first signal type may not need to be indicated separately.

The processing unit 620 is further configured to measure the reference signal of the first reference signal type according to the first indication information in the connected state, and obtain a first measurement value.

The processing unit 620 may make at least n measurements of the serving cell, where n is greater than or equal to 1.

The processing unit 620 may perform measurements on at least m neighbor cells of the serving cell, where m is greater than or equal to 1.

The processing unit 620 determines the result of the first decision based on the first measurement and the first threshold.

Specifically, the processing unit 620 measures a reference signal of a first reference signal type to obtain a first measurement value, and the processing unit 620 determines whether a relationship between the first measurement value and a first threshold satisfies a first criterion, where the first criterion may include a static criterion and a criterion not at a cell edge. It should be noted that the inactivity criterion and the out-of-cell-edge criterion may evaluate the approximate location and mobility information of the communication device to some extent.

It should be noted that, the relation that the relationship between the first measurement value and the first threshold satisfies the first criterion and needs to be satisfied may be referred to the description of the terminal device in the method 200, which is not described herein again.

The transceiving unit 610 is further configured to send second indication information to the network device, where the second indication information is used to indicate a result of the first determination.

In some embodiments, the terminal device determines that a relationship between the first measurement quantity and the first threshold satisfies a first criterion, and the transceiver unit 610 sends, to the network device, second indication information, where the second indication information is used to indicate that the relationship between the first measurement quantity and the first threshold satisfies the first criterion, optionally, the processing unit 620 may perform n measurements on the serving cell, and report measurement results satisfying the first criterion, where the n measurements may be sorted according to measurement time, and optionally, the terminal device may also perform measurements on m neighboring cells, and report measurement results satisfying the first criterion.

In some embodiments, the terminal device determines that a relationship between the first measurement quantity and the first threshold does not satisfy the first criterion, and sends second indication information to the network device, where the second indication information is used to indicate that the relationship between the first measurement quantity and the first threshold does not satisfy the first criterion, optionally, the processing unit 620 may perform n measurements on the serving cell, and report measurement results that do not satisfy the first criterion, where the n measurements may be sorted according to measurement time, and optionally, the processing unit 620 may also perform measurements on m neighboring cells, and report measurement results that do not satisfy the first criterion, where m and n are positive integers.

In some embodiments, the processing unit 620 determines whether a relationship between the first measurement quantity and the first threshold satisfies a first criterion, and the transceiver unit 610 sends second indication information to the network device, where the second indication information is used to indicate whether the relationship between the first measurement quantity and the first threshold satisfies the first criterion, optionally, the processing unit 620 may perform n measurements on the serving cell and report the n measurement results, and optionally, the processing unit 620 may also perform measurements on multiple neighboring cells and report whether the measurement results of m neighboring cells with the best cell quality satisfy the first criterion, where m and n are positive integers.

The second indication information may be transmitted to the network device through the communication device assistance information message, or may be transmitted to the network device through the MAC CE information.

It should be noted that, after the transceiver unit 610 sends the second indication information to the network device, the transceiver unit 610 may wait for the first time before sending the second indication information to the transceiver unit 610, or the first time may be sent by the network device to the transceiver unit 610, or may be default or preconfigured or protocol-specified by the transceiver unit 610. Optionally, after the transceiver unit 610 reports for L times, and still does not receive the third indication information of the network device, the transceiver unit 610 stops sending the second indication information to the network device, where the size of L may be sent to the transceiver unit 610 by the network device before, or may be default of the transceiver unit 610, and after the transceiver unit 610 stops sending the second indication information, if the first indication information is received again, the processing unit 620 performs measurement again and sends the second indication information according to the determination result.

Optionally, before the transceiver unit 610 reports the indication information, the network device may configure the maximum number L of times reported after meeting the first criterion to the processing unit 620, and when the processing unit 620 finds that the first criterion is met, start to send the second indication information to the network device, where a sending period is configured by the network device or configured by the processing unit 620 as default. Specifically, if the relaxation instruction information is received in the configuration sending process, then lean unit 610 stops sending the second instruction information, and starts to measure relaxation. The L measurement results reported by the transceiver unit 610 may all satisfy the first criterion, or may not satisfy the first criterion.

Optionally, after the transceiver unit 610 sends the second indication information to the network device, and does not receive the third indication information sent by the network device, the processing unit 620 may start the timer, and after the timer expires, judge whether the first criterion is met again, if yes, send the second indication information again, and if not, do not need to send the second indication information. The timer may be sent to the transceiver unit 610 by the network device before or may be specified by the protocol.

The transceiving unit 610 is further configured to receive third indication information sent by the network device, where the third indication information is used to indicate that the terminal device enters a measurement relaxed state.

It should be understood that the content of the measurement relaxation may be a frequency measurement relaxation, a cell measurement relaxation, a period measurement relaxation, etc. In other words, after the processing unit 620 enters the measurement relaxed state, the period may be measurement relaxed, and the network device may instruct the processing unit 620 to measure the period relaxed, by way of example and not limitation, the original measurement period may be measured every 5 minutes, and after entering the measurement relaxed state, the measurement period may be measured every 10 minutes. After the processing unit 620 enters the measurement relaxation state, measurement relaxation may be performed on a certain frequency, and by way of example and not limitation, the processing unit 620 may not perform measurement on the frequency. After the processing unit 620 enters the measurement relaxed state, measurement relaxation may be performed on a certain cell, and by way of example and not limitation, the processing unit 620 may not perform measurement on the cell. It should be noted that, the content of the processing unit 620 entering the measurement relaxation state may also be a combination of the above three, for example and without limitation, the network device may instruct the processing unit 620 to measure once in 20 minutes for a certain cell a and once in 10 minutes for a certain cell B, where the content of the measurement relaxation may be specifically indicated by the third indication information of the network device, or may instruct to enter the measurement relaxation state by the third indication information and the processing unit 620 measures the relaxed content by default.

Optionally, processing unit 620 performs measurement using the SSB signal or performs measurement using the CSI-RS signal, and after receiving the third indication information, may perform measurement relaxation on the relevant measurement corresponding to the two types of reference signals. Optionally, the processing unit 620 performs measurement using the SSB signal, and after receiving the third indication information, performs measurement relaxation on the relevant measurement corresponding to the SSB signal. Optionally, processing unit 620 performs measurement using the CSI-RS signal, receives the third indication information, and performs measurement relaxation on the relevant measurement corresponding to the CSI-RS signal.

The processing unit 620 is further adapted to end measuring the relaxed state.

Optionally, when the processing unit 620 measures the relaxed state, it finds that the relationship between the measurement quantity and the first threshold does not satisfy the first criterion, and may send fourth indication information to the network device, specifically, the fourth indication information may indicate that the relationship between the measurement quantity and the first threshold does not satisfy the first criterion, and the measurement quantity may be a measurement quantity corresponding to the first reference signal type indicated by the first indication information, or may be a measurement quantity of a reference signal of a type randomly measured by the processing unit 620 itself, which is not limited in this application. Optionally, the transceiving unit 610 may determine to end the measurement relaxed state by itself when sending the fourth indication information, or may wait for fifth indication information of the network device, where the fifth indication information is used to instruct the processing unit 620 to end the measurement relaxed state.

Optionally, in the foregoing steps, the third indication information sent by the network device may include a configuration of a timer, where the configuration of the timer may also be default for the processing unit 620, after the transceiver unit 610 receives the third indication information, the transceiver unit 610 enters the measurement relaxation state and starts the timer, and after the timer reaches the first duration, the processing unit 620 ends the measurement relaxation state. It should be noted that, if the processing unit 620 finds that the relationship between the measurement quantity and the first threshold does not satisfy the first criterion within the first time period, it may send fourth indication information to the network device, and decide to end the measurement relaxed state or wait for the fifth indication information of the network device to end the measurement relaxed state.

Optionally, in the foregoing step, the third indication information sent by the network device may include a timer configuration, and the timer configuration may also be default for the processing unit 620. After receiving the third indication information, the transceiving unit 610 enters a measurement relaxed state and starts the timer, before the timer reaches the first duration, the processing unit 620 finds that the relationship between the measurement amount and the first threshold does not satisfy the first criterion, and does not send the fourth indication information to the network device, when the timer reaches the first duration, the transceiving unit 610 sends the fourth indication information to the network device, and autonomously decides to end the measurement relaxed state or wait for the fifth indication information of the network device to end the measurement relaxed state.

It should be noted that, on the network device side, when the processing unit 620 measures the relaxed state, the network device receives the fourth indication information, or when the network device determines load balancing, or when it determines that the network device does not need to perform measurement relaxation according to the measurement result reported by the transceiving unit 610, the network device may send the fifth indication information to the transceiving unit, and instruct the processing unit 620 to end measuring the relaxed state. The fifth indication information may be a dedicated RRC message, a MAC CE message, or the like.

In some embodiments, the communication apparatus 600 may be the network device in the above method embodiment 300, and may also be a chip for implementing the functions of the network device in the above method embodiment. It should be understood that the communication device 600 may correspond to the steps of the network device in the method 300 of the embodiment of the present application. The communication device 600 includes:

the transceiving unit 610 sends first indication information to the terminal device, where the first indication information is used to indicate a first reference signal type.

A processing unit 620, configured to determine that the terminal device may enter the measurement relaxed state according to the second indication information.

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

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

In some embodiments, when the terminal device is in a connected state, the transceiver unit 610 transmits first indication information to the terminal device, where the first indication information may be transmitted through a broadcast message or may be transmitted through dedicated signaling, for example, a Radio Resource Control (RRC) reconfiguration message or a Medium Access Control (MAC) Control Element (CE) MAC CE, and the like. 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 to make the first decision.

In some embodiments, when the terminal device is in a connected state, all of the measurement configuration information received by the terminal device indicates that the terminal device performs measurement or reports using an SSB signal, the terminal device does not receive the first indication information but defaults to perform measurement for the first determination using the SSB signal, or when the terminal device is in a connected state, all of the measurement configuration information received by the terminal device indicates that the terminal device performs measurement or reports using a CSI-RS signal, the terminal device does not receive the first indication information but defaults to perform measurement for the first determination using the CSI-RS signal. It should be noted that other aspects of 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 for the measurement for the first decision, and the network device is not required to send the first indication information for the indication of the first reference signal type.

In some embodiments, when the terminal device is in an idle state or an inactive state, the transceiving unit 610 broadcasts first indication information to the terminal device, optionally, the first reference signal type indicated by the first indication information is an SSB signal, and optionally, the first reference signal type indicated by the first indication information is a CSI-RS signal. Correspondingly, when the terminal device enters the connection 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 receives the first indication information, that is, performs measurement and determination of the first determination, without performing configuration by using special measurement configuration information.

In a possible implementation manner, when the terminal device is in a connected state, the transceiving unit 610 sends first indication information to the terminal device, where the first indication information indicates a first threshold, or the first indication information indicates an offset of the first threshold, and the first threshold, or the first offset is a first threshold or an offset related to the SSB signal, the terminal device defaults to perform measurement on the SSB signal for a first decision, and if the first threshold, or the offset of the first threshold is the first threshold or the offset related to the CSI-RS, the terminal device defaults to perform measurement on the CSI-RS signal for the first decision. In this implementation, the first signal type may not need to be indicated separately.

The transceiver unit 610 is further configured to receive second indication information sent by the terminal device, where the second indication information is used to indicate a result of the first determination.

In some embodiments, the terminal device determines that a relationship between the first measurement quantity and the first threshold satisfies a first criterion, and sends second indication information to the transceiver unit 610, where the second indication information is used to indicate that the relationship between the first measurement quantity and the first threshold satisfies the first criterion, optionally, the terminal device may perform n measurements on the serving cell, and report measurement results satisfying the first criterion, where the n measurements may be sorted according to measurement time, and optionally, the terminal device may also perform measurements on m neighboring cells, and report measurement results satisfying the first criterion.

In some embodiments, the terminal device determines that the relationship between the first measurement quantity and the first threshold does not satisfy the first criterion, and sends, to the transceiver unit 610, second indication information, where the second indication information is used to indicate that the relationship between the first measurement quantity and the first threshold does not satisfy the first criterion, optionally, the terminal device may perform n-time measurement on the serving cell and report measurement results that do not satisfy the first criterion, where the n-time measurement may be sorted according to measurement time, and optionally, the terminal device may also perform measurement on m neighboring cells and report measurement results that do not satisfy the first criterion.

In some embodiments, the terminal device determines whether a relationship between the first measurement quantity and the first threshold meets a first criterion, and sends second indication information to the transceiver unit 610, where the second indication information is used to indicate whether the relationship between the first measurement quantity and the first threshold meets the first criterion, optionally, the terminal device may perform n measurements on the serving cell, and report whether each of the n measurement results meets the first criterion, where the n measurements may be sorted according to measurement time, and optionally, the terminal device may also perform measurements on m neighboring cells, and report whether the measurement results of the m neighboring cells meet the first criterion.

The second indication information may be transmitted to the transmitting/receiving unit 610 through a terminal device assistance information message, or may be transmitted to the transmitting/receiving unit 610 through MAC CE information.

After the terminal device sends the second indication information to the transceiver unit 610, and does not receive the third indication information sent by the transceiver unit 610, the terminal device may wait for the first time to send the second indication information again, where the first time may be sent to the terminal device before the transceiver unit 610, or may be default for the terminal device. Optionally, after L reports, the terminal device may stop sending the second indication information to the transceiver unit 610 after still not receiving the third indication information of the transceiver unit 610, where the size of L may be sent to the terminal device by the network device before, or may be default for the terminal device, and after the terminal device stops sending the second indication information, if the first indication information is received again, the terminal device measures again and sends the second indication information according to the determination result.

It should be noted that this step is optional, and if the processing unit 620 determines that the terminal device cannot enter the measurement relaxed state according to the second indication information, the transceiver unit 610 may not send the third indication information to the terminal device.

It is to be understood that the content of the measurement relaxation may be a frequency measurement relaxation, a cell measurement relaxation, a periodic measurement relaxation, etc. In other words, after the terminal device enters the measurement relaxed state, the period may be measured relaxed, and the processing unit 620 may instruct the terminal device to measure the period relaxed, by way of example and not limitation, the original measurement period may be measured every 5 minutes, and after entering the measurement relaxed state, the measurement period may be measured every 10 minutes. After the terminal device enters the measurement relaxation state, measurement relaxation may be performed on a certain frequency, and by way of example and not limitation, the terminal device may not perform measurement on the frequency. After entering the measurement relaxed state, the terminal device may perform measurement relaxation on a certain cell, and by way of example and not limitation, the terminal device may not perform measurement on the cell. It should be noted that, the content of the terminal device entering the measurement relaxation state may also be a combination of the above three types, for example and without limitation, the processing unit 620 may instruct the terminal device to measure once in a period of 20 minutes for a certain cell a, and once in a period of 10 minutes for a certain cell B, where the content of the measurement relaxation may be specifically indicated by the third indication information of the network device, or may instruct the terminal device to enter the measurement relaxation state and measure the relaxed content by default by the third indication information.

Optionally, when the terminal device measures the relaxed state, it finds that the relationship between the measurement quantity and the first threshold does not satisfy the first criterion, and may send fourth indication information to the transceiver unit 610, specifically, the fourth indication information may indicate that the relationship between the measurement quantity and the first threshold does not satisfy the first criterion, and the measurement quantity may be a measurement quantity corresponding to the first reference signal type indicated by the first indication information, or may also be a measurement quantity of a reference signal of a type randomly measured by the terminal device itself, which is not limited in this application. Optionally, the terminal device may determine to end the measurement relaxed state by itself when sending the fourth indication information, and may also wait for the fifth indication information of the transceiving unit 610, where the fifth indication information is used to indicate the terminal device to end the measurement relaxed state.

Optionally, in the above step, the third indication information sent by the transceiver unit 610 may include a configuration of a timer, where the configuration of the timer may also be default for the terminal, the terminal device enters the measurement relaxed state after receiving the third indication information and starts the timer at the same time, and when the timer reaches the first time length, the terminal device ends the measurement relaxed state. It should be noted that, if the terminal device finds that the relationship between the measurement quantity and the first threshold does not satisfy the first criterion within the first duration, it may send fourth indication information to the transceiver unit 610, and decide to end the measurement relaxed state or wait for the fifth indication information of the network device to end the measurement relaxed state.

Optionally, in the above step, the third indication information sent by the transceiver unit 610 may include a timer configuration, and the timer configuration may also be default for the terminal. After receiving the third indication information, the terminal device enters a measurement relaxed state and starts the timer, 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 fourth indication information to the transceiver unit 610, when the timer reaches the first duration, the terminal device sends fourth indication information to the transceiver unit 610, and automatically determines to end the measurement relaxed state or wait for the fifth indication information of the transceiver unit 610 to end the measurement relaxed state.

It should be noted that, on the communication apparatus side, during the period when the terminal device measures the relaxed state, the transceiver unit 610 receives the fourth indication information, or when the processing unit 620 determines that the load is balanced, or determines that the terminal device does not need to perform measurement relaxation according to the measurement result reported by the terminal device, the transceiver unit may send the fifth indication information to the terminal device, and instruct the terminal device to end the measurement relaxed state. The fifth indication information may be a dedicated RRC message, a MAC CE message, or the like.
