As described above, in 5G communication systems, the coverage of Non-Terrestrial Networks (NTN) cells generally includes some Terrestrial Networks (TN) cells. Due to a large transmission delay of the NTN cells, User equipment (UEs) will be preferentially handed over the TN cells as serving cells.

In the related arts, a network configures a connected UE with a measurement identity, a reporting configuration and a measurement object at a frequency where a TN cell is located, and the UE measures the TN cell based on the configuration by the network and hands over to the TN cell based on a measurement result.

However, in the related arts, when there is no TN cell coverage near an area where the UE (such as a UE1inFIG.1A) is located, the UE will still always measure the TN cell, which will cause power consumption and increase the power consumption.

A method and apparatus for measuring a reference signal, a user equipment, a network side device and a storage medium provided by embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

FIG.1is a schematic flowchart of a method for measuring a reference signal provided by an embodiment of the present disclosure. The method is performed by a UE. As shown inFIG.1, the method for measuring the reference signal may include steps101to104.

In the step101, configuration information sent by a network side device is received.

It should be noted that the method for measuring the reference signal in embodiments of the present disclosure can be applied to any UE. The UE may refer to a device that provides speech and/or data connectivity for the user. The UE may communicate with one or more core networks via a Radio Access Network (RAN). The UE may be an Internet of Things terminal, such as a sensor device, a mobile phone (or a “cellular” phone), and a computer having an Internet of Things terminal, for example, a fixed, portable, pocket-sized, handheld, computer built-in or vehicle-mounted device. For example, it may be a station (STA), a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, an access point, a remote terminal, an access terminal, a user terminal, or a user agent. Alternatively, the UE may also be a device of an unmanned aerial vehicle. Alternatively, the UE may also be an in-vehicle device, for example, a trip computer with a wireless communication function, or a wireless terminal external to the trip computer. Alternatively, the UE may also be a roadside device, for example, a street light, a signal light, or other roadside device with a wireless communication function, etc.

In an embodiment of the present disclosure, the network side device may include a base station or a core network entity.

In an embodiment of the present disclosure, the configuration information may specifically include a trigger condition corresponding to a frequency point to be measured and/or a trigger condition corresponding to a cell to be measured. In an embodiment of the present disclosure, the configuration information may only include the trigger condition corresponding to the frequency point to be measured. In another embodiment of the present disclosure, the configuration information may only include the trigger condition corresponding to the cell to be measured. In yet another embodiment of the present disclosure, the configuration information may include the trigger condition corresponding to the cell to be measured and the trigger condition corresponding to the frequency point to be measured.

In an embodiment of the present disclosure, the trigger condition corresponding to the frequency point to be measured may be configured to trigger an update of a measurement configuration of the frequency point to be measured. For example, in an embodiment of the present disclosure, a trigger condition of a frequency point to be measured A may be configured to trigger an update of a measurement configuration of the frequency point A to be measured.

In an embodiment of the present disclosure, the trigger condition corresponding to the cell to be measured may be configured to trigger an update of a measurement configuration of the cell to be measured. For example, in an embodiment of the present disclosure, a trigger condition of a cell to be measured B may be configured to trigger an update of a measurement configuration of the cell to be measured B.

In another embodiment of the present disclosure, the trigger condition corresponding to the frequency point to be measured may be configured to trigger an update of a measurement configuration of another frequency points to be measured. For example, in an embodiment of the present disclosure, the trigger condition of the frequency point to be measured A may be configured to trigger an update of a measurement configuration of a frequency point to be measured C.

In an embodiment of the present disclosure, the trigger condition corresponding to the cell to be measured may be configured to trigger an update of a measurement configuration of another cell to be measured. For example, in an embodiment of the present disclosure, the trigger condition of the cell to be measured B may be configured to trigger an update of a measurement configuration of a cell to be measured D.

It should be noted that in an embodiment of the present disclosure, the other frequency point/cell to be measured may be configured by the network. In another embodiment of the present disclosure, the other frequency point/cell to be measured may also be specified by a protocol. In yet another embodiment of the present disclosure, the other frequency point/cell to be measured may also be determined by the UE.

Further, in an embodiment of the present disclosure, the frequency point/cell to be measured configured by the network may be included in information sent by the network based on an update request (that is, information sent, based on the update request, by the network side device which is received by the UE in the subsequent step103).

In an embodiment of the present disclosure, the frequency point to be measured may be a frequency point corresponding to any cell, and the cell to be measured may be any cell. For example, in an embodiment of the present disclosure, the frequency point to be measured may be a frequency point corresponding to a TN cell in a NTN cell, and the cell to be measured may be the TN cell in the NTN cell.

Further, in an embodiment of the present disclosure, the trigger condition corresponding to the cell to be measured may include at least one of:the UE failing to detect a measurement reference signal of the cell to be measured;the UE failing to detect a measurement reference signal of a frequency point corresponding to the cell to be measured;the UE failing to obtain a measurement result of the cell to be measured; andthe UE measuring that a measurement result of the cell to be measured is less than a first threshold value.

It should be noted that in an embodiment of the present disclosure, the trigger condition corresponding to the cell to be measured may include any of the above items. In another embodiment of the present disclosure, the trigger condition corresponding to the cell to be measured may include a combination of the above any several items.

In an embodiment of the present disclosure, the above any several items may be combined using a logical relationship such as AND, OR, NOT, etc.

In an embodiment of the present disclosure, the trigger condition corresponding to the frequency point to be measured may include at least one of:the UE failing to detect a measurement reference signal of a cell corresponding to the frequency point to be measured;the UE failing to detect a measurement reference signal of the frequency point to be measured;the UE failing to obtain a measurement result of the cell corresponding to the frequency point to be measured;the UE measuring that the maximum value of measurement results of the frequency point to be measured is less than a second threshold value;the UE measuring that the minimum value of the measurement results of the frequency point to be measured is less than a third threshold value; andthe UE measuring that an average value of the measurement results of the frequency point to be measured is less than a fourth threshold value.

In an embodiment of the present disclosure, the first threshold value, the second threshold value, the third threshold value and the fourth threshold value may be the same. In another embodiment of the present disclosure, the first threshold value, the second threshold value, the third threshold value and the fourth threshold value may be different.

In an embodiment of the present disclosure, the trigger condition corresponding to the frequency point to be measured may include any of the above items. In another embodiment of the present disclosure, the trigger condition corresponding to the frequency point to be measured may include a combination of the above any several items.

In an embodiment of the present disclosure, the above any several items may be combined by using the logical relationship such as AND, OR, NOT, etc.

In an embodiment of the present disclosure, the measurement reference signal may include but is not limited to one or more of:a Synchronization Signal Block (SSB);a Channel State Information-Reference Signal (CSI-RS); andother reference signals that can be used for the measurement.

In an embodiment of the present disclosure, the measurement result includes but is not limited to one or more of:a Reference Signal Received Power (RSRP);a Reference Signal Received Quality (RSRQ); anda Signal-to-Interference plus Noise Ratio (SINR).

In an embodiment of the present disclosure, the method for the UE to receive the configuration information sent by the network side device may include at least one of:receiving the configuration information sent by the network side device through a system message;receiving the configuration information sent by the network side device through a Radio Resource Control (RRC) message;receiving the configuration information sent by the network side device through a Media Access Control Address Control Element (MAC CE) signaling; andreceiving the configuration information sent by the network side device through a Downlink Control Information (DCI) signaling.

In the step102, an update request is sent to the network side device based on the trigger condition.

In an embodiment of the present disclosure, the method for the UE to send the update request to the network side device based on the trigger condition may include: determining whether the UE satisfies the trigger condition, and sending the update request to the network side device based on the determination result. It should be noted that, in an embodiment of the present disclosure, there is a correspondence between the determination result and the update request. Different determination results correspond to sending different update requests. The UE may determine the sent update request based on the correspondence and the determination result.

In an embodiment of the present disclosure, the correspondence between the determination result and the update request may include:when the determination result is that the UE satisfies the trigger condition, it means that the UE is currently unable to detect the cell to be measured and/or the frequency point to be measured (that is, the UE is not within the coverage of the frequency point to be measured and/or the cell to be measured, or the UE is far from the cell to be measured and/or the frequency point to be measured). In this case, the UE may send to the network side device the update request for requesting to reduce a measurement opportunity, so as to reduce the measurement opportunity for the cell to be measured and/or the frequency point to be measured by the UE, preventing the UE from measuring the cell to be measured and/or the frequency point to be measured that cannot be measured by UE.

When the determination result is that the UE does not satisfy the trigger condition, it means that the UE is able to detect the cell to be measured and/or the frequency point to be measured (that is, the UE is close to the cell to be measured and/or the frequency point to be measured). In this case, the UE may send to the network side device an update request for requesting to increase the measurement opportunity or maintain the current measurement opportunity to maintain or increase the measurement opportunity for the cell to be measured and/or the frequency point to be measured by the UE, thereby ensuring that the UE can perform a normal measurement for the cell to be measured and/or the frequency point to be measured.

Regarding the method for obtaining the correspondence and a specific content included in the update request as mentioned above, detailed introduction will be given in subsequent embodiments.

In the step103, information sent by the network side device based on the update request is received.

In an embodiment of the present disclosure, when update requests sent by the UE are different, content of information sent by the network side device based on the update requests will also vary.

Specifically, in an embodiment of the present disclosure, when the UE sends to the network side device the update request for requesting to reduce the measurement opportunity, the content included in the information sent by the network side device to the UE may be content that makes the UE reduce the measurement opportunity. In another embodiment of the present disclosure, when the UE sends to the network side device the update request for requesting to increase the measurement opportunity or maintain the current measurement opportunity, the content included in the information sent by the network side device to the UE may be content that makes the UE maintain the current measurement opportunity or increase the measurement opportunity.

In the step104, the frequency point to be measured and/or the cell to be measured are measured based on the information.

In an embodiment of the present disclosure, the method for measuring the frequency point to be measured and/or the cell to be measured based on the information may include: measuring the frequency point to be measured and/or the cell to be measured based on the content included in the information.

As can be seen from the foregoing content, in an embodiment of the present disclosure, when the UE sends to the network side device the update request for requesting to reduce the measurement opportunity, the content included in the information received by the UE from the network side device is the content that enables the UE to reduce the measurement opportunity. Therefore, when the UE measures the frequency point to be measured and/or the cell to be measured based on the content, the measurement opportunity will be greatly reduced, which can prevent the UE from measuring the cell to be measured and/or the frequency point to be measured that cannot be measured by the UE, so as to reduce the power consumption.

In another embodiment of the present disclosure, when the UE sends to the network side device the update request for requesting to increase the measurement opportunity or maintain the current measurement opportunity, the content included in the information received by the UE from the network side device is content that enables the UE to maintain the current measurement opportunity or increase the measurement opportunity. Therefore, when the UE measures the frequency point to be measured and/or the cell to be measured based on the content, the measurement opportunity will be maintained or increased, which ensures that the UE performs the normal measurement for the cell to be measured and/or the frequency point to be measured, so that subsequent processes proceed normally.

Further, in an embodiment of the present disclosure, the information sent by the network side device to the UE may further include a valid duration and/or a valid time window. In an embodiment of the present disclosure, the valid duration and/or the valid time window may be specifically configured to indicate “a specific measurement time period in which the UE measures the frequency point to be measured and/or the cell to be measured based on the information sent by the network side device”. In an embodiment of the present disclosure, the UE may specifically measure, within the valid duration and/or the valid time window, the frequency point to be measured and/or the cell to be measured based on the content included in the information sent by the network side device, and measure, beyond the valid duration and/or the valid time window, the frequency point to be measured and/or the cell to be measured based on an original measurement configuration.

For example, in an embodiment of the present disclosure, it is assumed that the information sent by the network side device to the UE includes the valid duration, and the valid duration is ten minutes since the information sent by the network side device is received. Therefore, the UE may measure, within the ten minutes since receiving the information sent by the network side device, the frequency point to be measured and/or the cell to be measured based on the content of the information, and measure, beyond the ten minutes since receiving the information sent by the network side device, the frequency point to be measured and/or the cell to be measured based on the original measurement configuration.

To sum up, in the method for measuring the reference signal provided in the present disclosure, the UE receives the configuration information sent by the network side device, and the configuration information includes the trigger condition corresponding to the frequency point to be measured and/or the trigger condition corresponding to the cell to be measured, and then the UE sends the update request to the network side device based on the trigger condition, and receives the information sent, based on the update request, by the network side device. Finally, the UE measures the cell the frequency point to be measured and/or the cell to be measured based on the information sent by the network side device. In embodiments of the present disclosure, the UE sending the update request to the network side device based on the trigger condition is specifically: when the UE satisfies the trigger condition (i.e., the UE cannot measure the cell to be measured and/or the frequency point to be measured), the UE sends to the network side device the update request for requesting to reduce the measurement opportunity, so as to reduce the UE's measurement opportunity, which prevents the UE from measuring the cell to be measured and/or the frequency point to be measured that cannot be measured by the UE, thereby reducing the power consumption.

FIG.2is a schematic flowchart of a method for measuring a reference signal provided by an embodiment of the present disclosure. The method is performed by a UE. As shown inFIG.2, the method for measuring the reference signal may include steps201to205.

In the step201, configuration information sent by a network side device is received.

In an embodiment of the present disclosure, the configuration information may include a trigger condition corresponding to a frequency point to be measured and/or a trigger condition corresponding to a cell to be measured, and the trigger condition is configured to trigger an update of a measurement configuration of the frequency point to be measured and/or a measurement configuration of the cell to be measured. For the detailed introduction related to the step201, reference may be made to the above description, which is not repeated in embodiments of the present disclosure here.

In the step202, it is determined whether the UE satisfies the trigger condition.

In an embodiment of the present disclosure, the method for determining whether the UE satisfies the trigger condition may include the following first step and second step.

In the first step, a predefined determination method is determined

In an embodiment of the present disclosure, the predefined determination method may include at least one of:a first method: it is determined whether the UE satisfies the trigger condition based on the latest measurement (that is, it is determined whether, during the latest measurement, the UE cannot detect a measurement reference signal of the cell to be measured, and/or whether, during the latest measurement, the UE cannot detect a measurement reference signal of a frequency point corresponding to the cell to be measured, and/or whether, during the latest measurement, the UE cannot obtain a measurement result of the cell to be measured, and/or whether, during the latest measurement, the UE cannot detect a measurement reference signal of a cell corresponding to the frequency point to be measured, and/or whether, during the latest measurement, the UE cannot detect a measurement reference signal of the frequency point to be measured, and/or whether, during the latest measurement, the UE cannot obtain a measurement result of the cell corresponding to the frequency point to be measured).

A second method: it is determined whether the UE always satisfies the trigger condition in measurements within the most recent first duration (that is, it is determined whether, in the measurements within the most recent first duration, the UE always cannot detect the measurement reference signal of the cell to be measured, and/or whether, in the measurements within the most recent first duration, the UE always cannot detect a measurement reference signal of a frequency point corresponding to the cell to be measured, and/or whether, in the measurements within the most recent first duration, the UE always cannot obtain the measurement result of the cell to be measured, and/or whether, in the measurements within the most recent first duration, the UE always cannot detect the measurement reference signal of the cell corresponding to the frequency point to be measured, and/or whether, in the measurements within the most recent first duration, the UE always cannot detect the measurement reference signal of the frequency point to be measured, and/or whether, in the measurements within the most recent first duration, the UE always cannot obtain the measurement result of the cell corresponding to the frequency point to be measured).

A third method: it is determined whether the UE always satisfies the trigger condition in measurements within a first time window (that is, it is determined whether, in the measurements within the first time window, the UE always cannot detect the measurement reference signal of the cell to be measured, and/or whether, in the measurements within the first time window, the UE always cannot detect a measurement reference signal of a frequency point corresponding to the cell to be measured, and/or whether, in the measurements within the first time window, the UE always cannot obtain the measurement result of the cell to be measured, and/or whether, in the measurements within the first time window, the UE always cannot detect the measurement reference signal of the cell corresponding to the frequency point to be measured, and/or whether, in the measurements within the first time window, the UE always cannot detect the measurement reference signal of the frequency point to be measured, and/or whether, in the measurements within the first time window, the UE always cannot obtain the measurement result of the cell corresponding to the frequency point to be measured).

A fourth method: it is determined whether the UE always satisfies the trigger condition in the most recent first quantity of measurements (that is, it is determined whether, in the most recent first quantity of measurements, the UE always cannot detect the measurement reference signal of the cell to be measured, and/or whether, in the most recent first quantity of measurements, the UE always cannot detect a measurement reference signal of a frequency point corresponding to the cell to be measured, and/or whether, in the most recent first quantity of measurements, the UE always cannot obtain the measurement result of the cell to be measured, and/or whether, in the most recent first quantity of measurements, the UE always cannot detect the measurement reference signal of the cell corresponding to the frequency point to be measured, and/or whether, in the most recent first quantity of measurements, the UE always cannot detect the measurement reference signal of the frequency point to be measured, and/or whether, in the most recent first quantity of measurements, the UE always cannot obtain the measurement result of the cell corresponding to the frequency point to be measured).

It should be noted that in an embodiment of the present disclosure, the method for determining the first duration, the first time window and the first quantity as mentioned above may include at least one of:performing determination based on a system message sent by the network side device;performing the determination based on a RRC message sent by the network side device;performing the determination based on a provision of a protocol;independently performing the determination by the UE;performing the determination based on a MAC CE signaling sent by the network side device; orperforming the determination based on a DCI signaling sent by the network side device.

In an embodiment of the present disclosure, a manner in which the UE determines the predefined determination method may include at least one of:determining the predefined determination method based on an indication by the network side device (for example, the network side device indicates to determine the above second method as the predefined determination method);determining the predefined determination method based on the provision of the protocol (for example, the above third method is determined as the predefined determination method based on the provision of the protocol); andindependently determining, by the UE, the predefined determination method (for example, the UE independently determines the above fourth method as the predefined determination method).

Further, in an embodiment of the present disclosure, the determined predefined determination method may include any of the above methods. In another embodiment of the present disclosure, the determined predefined determination method may include a combination of the above any several methods.

For example, in an embodiment of the present disclosure, if the network side device only configures the UE with the first duration, only the above second method may be determined as the predefined determination method. In another embodiment of the present disclosure, if the network side device configures the UE with the first duration and the first quantity, the UE can select one of the second method and the fourth method to be determined as the predefined determination method, or determine both second method and the fourth method as the predefined determination method.

In the second step, it is determined whether the UE satisfies the trigger condition based on the predefined determination method.

In an embodiment of the present disclosure, when predefined determination methods are different, processes of determining whether the UE satisfies the trigger condition are also different.

Specifically, in an embodiment of the present disclosure, if the above first method is determined as the predefined determination method, and the trigger condition is that the UE cannot detect the measurement reference signal of the cell to be measured, then a specific process of determining, based on the first method, whether the UE satisfies the trigger condition may be determining, in the latest measurement opportunity, whether the UE cannot detect the measurement reference signal of the frequency point to be measured, and when the UE cannot detect the measurement reference signal of the frequency point to be measured, the UE is considered to satisfy the trigger condition, otherwise, the UE is considered not to satisfy the trigger condition.

In another embodiment of the present disclosure, if the above second method is determined as the predefined determination method, and the trigger condition is that the UE cannot obtain the measurement result of the cell to be measured, then a specific process of determining, based on the second method, whether the UE satisfies the trigger condition may be determining, in all measurement opportunities within the most recent first duration, whether the UE always cannot obtain the measurement result of the cell to be measured, and when the UE always cannot obtain the measurement result of the cell to be measure within the most recent first duration, the UE is considered to satisfy the trigger condition, otherwise, the UE is considered not to satisfy the trigger condition.

In yet another embodiment of the present disclosure, if the above third method is determined as the predefined determination method, and the trigger condition is that the UE cannot obtain the measurement result of the cell to be measured, then a specific process of determining, based on the third method, whether the UE satisfies the trigger condition may be determining, in all measurement opportunities within the first time window, whether the UE always cannot obtain the measurement result of the cell to be measured, and when the UE always cannot obtain the measurement result of the cell to be measured within the first time window, the UE is considered to satisfy the trigger condition, otherwise, the UE is considered not to satisfy the trigger condition.

In still another embodiment of the present disclosure, if the above fourth method is determined as the predefined determination method, and the trigger condition is that the UE cannot detect the measurement reference signal of the frequency point corresponding to the cell to be measured, then a specific process of determining, based on the fourth method, whether the UE satisfies the trigger condition may be determining, in all of the most recent first quantity of measurement opportunities, whether the UE always cannot detect the measurement reference signal of the frequency point corresponding to the cell to be measured, and when the UE cannot detect the measurement reference signal of the frequency point corresponding to the cell to be measured in all of the most recent first quantity of measurement opportunities, the UE is considered to satisfy the trigger condition, otherwise, the UE is considered not to satisfy the trigger condition.

In the step203, an update request is sent to the network side device based on the determination result.

In an embodiment of the present disclosure, the method for sending the update request to the network side device based on the determination result may include the following steps a and b.

In the step a, a correspondence between the determination result and the update request is determined.

In an embodiment of the present disclosure, the correspondence between the determination result and the update request may specifically include:when the determination result is that the UE satisfies the trigger condition, the UE sends to the network side device an update request for requesting to reduce a measurement opportunity. In an embodiment of the present disclosure, the update request for requesting to reduce the measurement opportunity may include at least one of:the UE satisfying the trigger condition;a request to stop the measurement of the frequency point to be measured and/or the cell to be measured;a request to reduce the measurement opportunity for the frequency point to be measured and/or the cell to be measured; anda first parameter of the measurement configuration recommended by the UE, where the first parameter is more relaxed than an original parameter of the measurement configuration (for example, a Synchronization Signal Block Measurement Timing Configuration (SMTC) period corresponding to the original parameter is 5 ms, and a SMTC period corresponding to the first parameter may be 20 ms).

When the determination result is that the UE does not satisfy the trigger condition, the UE sends to the network side device an update request for requesting to increase the measurement opportunity or to maintain the current measurement opportunity. In an embodiment of the present disclosure, the update request for requesting to increase the measurement opportunity or to maintain the current measurement opportunity may include at least one of:the UE failing to satisfy the trigger condition;maintaining the current measurement opportunity for the frequency point to be measured and/or the cell to be measured;a request to increase the measurement opportunity for the frequency point to be measured and/or the cell to be measured; anda second parameter of the measurement configuration recommended by the UE, where the original parameter of the measurement configuration is more relaxed than the second parameter (for example, a measurement period corresponding to the original parameter is 5 ms, and a measurement period corresponding to the second parameter may be 3 ms).

Further, in an embodiment of the present disclosure, the method for the UE to determine the correspondence between the determination result and the update request may include at least one of:obtaining the correspondence included in the configuration information;determining the correspondence based on the provision of the protocol; andindependently determining, by the UE, the correspondence.

In the step b, a corresponding update request is sent to the network side device based on the correspondence and the determination result.

In an embodiment of the present disclosure, the method for sending the corresponding update request to the network side device based on the correspondence and the determination result may include: when the determination result determined in the step202is the UE satisfies the trigger condition, the UE may determine, based on the correspondence, that the update request corresponding to the determination result that “the UE satisfies the trigger condition” is the update request for requesting to reduce the measurement opportunity, so that the UE can send to the network side device the update request for requesting to reduce the measurement opportunity. When the determination result determined in the step202is the UE does not satisfy the trigger condition, the UE may determine, based on the correspondence, that the update request corresponding to the determination result that “the UE does not satisfy the trigger condition” is the update request for requesting to increase the measurement opportunity or maintain the current measurement opportunity, so that the UE may send to the network side device the update request for requesting to increase the measurement opportunity or maintain the current measurement opportunity.

In the step204, information sent by the network side device based on the update request is received.

In an embodiment of the present disclosure, when update requests sent by the UE to the network side device are different, content of the information sent by the network side device that is received by the UE is also different.

Specifically, in an embodiment of the present disclosure, when the UE sends to the network side device the update request for requesting to reduce the measurement opportunity, the information sent, based on the update request for requesting to reduce the measurement opportunity by the network side device which is received by the UE may include at least one of:a reconfigured first measurement configuration, where the first measurement configuration is more relaxed than the original measurement configuration (for example, a measurement period of the original measurement configuration is 5 ms, then a measurement period of the first measurement configuration may be 20 ms);a message to stop measurement;a first new parameter corresponding to at least one measurement configuration in the original measurement configuration, where the first new parameter is more relaxed than the original parameter corresponding to the measurement configuration (for example, an original parameter corresponding to a measurement frequency in the original measurement configuration includes 3 megahertz (GHZ) and 10 GHZ, then the first new parameter may only include 3 GHZ); anda first adjustment factor corresponding to the at least one measurement configuration in the original measurement configuration, where the first adjustment factor is configured to relax the measurement configuration (for example, the first adjustment factor may be an expansion factor of the measurement period).

When the UE sends to the network side device the update request for requesting to increase the measurement opportunity or to maintain the current measurement opportunity, the information sent, based on the update request for requesting to increase the measurement opportunity or to maintain the current measurement opportunity, by the network side device that is received by the UE may include at least one of:a message to maintain the original measurement configuration;a reconfigured second measurement configuration, where the original measurement configuration is more relaxed than the second measurement configuration (for example, a measurement period of the original measurement configuration is 5 ms, then a measurement period of the second measurement configuration may be 3 ms);a second new parameter corresponding to at least one measurement configuration in the original measurement configuration, where the original parameter corresponding to the measurement configuration is more relaxed than the second new parameter (for example, an original parameter corresponding to a measurement frequency in the original measurement configuration includes 3 GHZ and 10 GHZ, then the second new parameter may only include 3 GHZ, 10 GHZ and 5 GHZ); anda second adjustment factor corresponding to the at least one measurement configuration in the original measurement configuration, where the second adjustment factor is configured to increase the measurement opportunity (for example, the second adjustment factor may be a reduction factor of the measurement period).

In the step205, the frequency point to be measured and/or the cell to be measured are measured based on the information.

In an embodiment of the present disclosure, the method for measuring the frequency point to be measured and/or the cell to be measured based on the information may include: measuring the frequency point to be measured and/or the cell to be measured based on the content included in the information.

Further, in an embodiment of the present disclosure, the information sent by the network side device to the UE may further include a valid duration and/or a valid time window. In an embodiment of the present disclosure, the valid duration and/or the valid time window may be specifically configured to indicate “a specific measurement time period in which the UE measures the frequency point to be measured and/or the cell to be measured based on the information sent by the network side device”. In an embodiment of the present disclosure, the UE may specifically measure, within the valid duration and/or the valid time window, the frequency point to be measured and/or the cell to be measured based on the content included in the information sent by the network side device, and measure, beyond the valid duration and/or the valid time window, the frequency point to be measured and/or the cell to be measured based on an original measurement configuration.

It should also be noted that in an embodiment of the present disclosure, when the content included in the information sent by the network side device to the UE is different, measurement manners of the frequency point to be measured and/or the cell to be measured by the UE are also different.

Specifically, in an embodiment of the present disclosure, if the information sent by the network side device to the UE includes the message to stop the measurement, and the validity period is ten minutes since the information sent by the network side device is received, then after receiving the information sent by the network side device, the UE may stop, within the ten minutes since receiving the information sent by the network side device, measuring the frequency point to be measured and/or the cell to be measured, and may restore, beyond the ten minutes since receiving the information sent by the network side device, the measurement for the frequency point to be measured and/or the cell to be measured.

In another embodiment of the present disclosure, if the information sent by the network side device to the UE includes the reconfigured first measurement configuration, and the valid duration is ten minutes since the information sent by the network side device is received, then after receiving the information sent by the network side device, the UE may measure, within the ten minutes since receiving the information sent by the network side device, the frequency point to be measured and/or the cell to be measured based on the reconfigured first measurement configuration, and measure, beyond the ten minutes since receiving the information sent by the network side device, the frequency point to be measured and/or the cell to be measured based on the original measurement configuration.

To sum up, in the method for measuring the reference signal provided in the present disclosure, the UE receives the configuration information sent by the network side device, and the configuration information includes the trigger condition corresponding to the frequency point to be measured and/or the trigger condition corresponding to the cell to be measured, and then the UE sends the update request to the network side device based on the trigger condition, and receives the information sent, based on the update request, by the network side device. Finally, the UE measures the cell the frequency point to be measured and/or the cell to be measured based on the information sent by the network side device. In embodiments of the present disclosure, the UE sending the update request to the network side device based on the trigger condition is specifically: when the UE satisfies the trigger condition (i.e., the UE cannot measure the cell to be measured and/or the frequency point to be measured), the UE sends to the network side device the update request for requesting to reduce the measurement opportunity, so as to reduce the UE's measurement opportunity, which prevents the UE from measuring the cell to be measured and/or the frequency point to be measured that cannot be measured by the UE, thereby reducing the power consumption.

Further, in an embodiment of the present disclosure, the trigger condition corresponding to the cell to be measured may include at least one of:the UE failing to detect a measurement reference signal of the cell to be measured;the UE failing to detect a measurement reference signal of a frequency point corresponding to the cell to be measured;the UE failing to obtain a measurement result of the cell to be measured; andthe UE measuring that a measurement result of the cell to be measured is less than a first threshold value.

It should be noted that in an embodiment of the present disclosure, the trigger condition corresponding to the cell to be measured may include any of the above items. In another embodiment of the present disclosure, the trigger condition corresponding to the cell to be measured may include a combination of the above any several items.

In an embodiment of the present disclosure, after receiving the trigger condition in the configuration information sent by the network side device, the UE may determine, based on a predefined determination method, whether the UE satisfies the trigger condition, and send the update request to the network side device based on the determination result. In an embodiment of the present disclosure, the predefined determination method may be indicated by the network side device to the UE.

It should be noted that in an embodiment of the present disclosure, there is a correspondence between the determination result and the update request, and different determination results correspond to sending different update requests. Therefore, when the determination results obtained by the UE are different, the network side device will receive different update requests.

In an embodiment of the present disclosure, the correspondence between the determination result and the update request may include:when the determination result is that the UE satisfies the trigger condition, it means that the UE is currently unable to detect the cell to be measured and/or the frequency point to be measured (that is, the UE is not within the coverage of the frequency point to be measured and/or the cell to be measured, or the UE is far from the cell to be measured and/or the frequency point to be measured). In this case, the network side device will receive the update request for requesting to reduce the measurement opportunity which is sent by the UE.

When the determination result is that the UE does not satisfy the trigger condition, it means that the UE is able to detect the cell to be measured and/or the frequency point to be measured (that is, the UE is close to the cell to be measured and/or the frequency point to be measured). In this case, the network side device will receive the update request for requesting to increase the measurement opportunity or maintain the current measurement opportunity which is sent by the UE.

In an embodiment of the present disclosure, the correspondence between the determination result and the update request may be carried in the configuration information and sent to the UE by the network side device.

In another embodiment of the present disclosure, when the network side device receives the update request for requesting to increase the measurement opportunity or maintain the current measurement opportunity, the content included in the information sent by the network side device to the UE may be content that enables the UE to maintain the current measurement opportunity or increase the measurement opportunity, so as to maintain or increase the measurement opportunity of the UE.

Further, in an embodiment of the present disclosure, the information sent by the network side device to the UE may further include a valid duration and/or a valid time window. In an embodiment of the present disclosure, the valid duration and/or the valid time window may be specifically configured to indicate “a specific measurement time period in which the UE measures the frequency point to be measured and/or the cell to be measured based on the information sent by the network side device”. In an embodiment of the present disclosure, the UE may specifically measure, within the valid duration and/or the valid time window, the frequency point to be measured and/or the cell to be measured based on the content included in the information sent by the network side device, and measure, beyond the valid duration and/or the valid time window, the frequency point to be measured and/or the cell to be measured based on an original measurement configuration.
