Description

Control method and device of radio link failure timer
Technical Field
The present invention relates to the field of wireless communications technologies, and in particular, to a method and an apparatus for controlling a radio link failure timer.
Background
Currently, in an LTE (Long Term evolution ) system, a user equipment may implement detection of a radio link failure by the following method:
The user equipment periodically performs quality evaluation on an RLM (Radio Link Monitor) resource, when a physical layer of the user equipment detects that the signal quality of a serving cell is lower than a certain threshold, the physical layer of the user equipment sends an out-of-step indication to a high layer, and when a continuous preset number of out-of-step indications occur, the user equipment starts a Radio Link failure monitoring timer. When the user equipment measures and reports a measurement event meeting the requirement of network side configuration, and the measurement event configures a function of a radio link failure timer for reporting in advance, the radio link failure timer for reporting in advance is started. When the radio link failure timer reported in advance is overtime, the user equipment does not receive the switching command and the radio link failure monitoring timer does not stop running, the user equipment can trigger a radio link failure mechanism in advance.
In an NR (New Radio Access Technology) system, a multi-beam mechanism exists in a bottom layer of a user equipment, and the bottom layer of the user equipment has a beam management mechanism.

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

step 101, the user equipment controls the radio link failure timer reported in advance according to the state of the beam failure recovery operation.
After the user equipment starts the radio link failure timer reported in advance, the radio link failure timer reported in advance is controlled according to the state of the beam failure recovery operation. The user equipment controls the radio link failure timer reported in advance by combining the state of the beam failure recovery operation, so that the wrong judgment of the radio link failure caused by not considering the state of the beam failure recovery operation is avoided, an unnecessary reconstruction process is introduced, and the waste of air interface signaling resources is avoided.
Optionally, the ue in the embodiment of the present invention starts a radio link failure early reporting timer when determining that any one of the following conditions is satisfied:
the first condition is as follows: the user equipment starts a radio link failure monitoring timer, and after the user equipment determines that the quality of the measurement signal meets the condition of triggering the report of the measurement report, the user equipment starts a radio link failure timer reported in advance.
The configuration of the measurement report comprises measurement configuration of a network side for starting a function of reporting a radio link failure timer in advance;
the radio link failure monitoring timer is started based on the out-of-step indication reported by the bottom layer;
specifically, after the bottom layer of the user equipment continuously sends out a preset number of out-of-step instructions to the high layer, the user equipment starts a radio link failure monitoring timer.
And a second condition: after the user equipment determines that the quality of the measurement signal meets the condition of triggering the report of the measurement report, a radio link failure timer for reporting in advance is started.
The configuration of the measurement report comprises measurement configuration of a network side for starting a function of reporting a radio link failure timer in advance.
And (3) carrying out a third condition: and the user equipment determines that the quality of the measured signal meets the preset condition configured by the network side, and starts the radio link failure timer reported in advance.
The preset condition is that the measured signal quality is within a preset range configured by a network side within a preset time.
The state of the beam failure recovery operation in the embodiment of the present invention includes, but is not limited to, the following states:
a beam failure recovery operation failed, a beam failure recovery operation succeeded, a beam failure recovery operation is in progress, and a beam failure recovery operation is not in progress.
When the beam failure recovery operation fails, the high layer can be notified in a form that the bottom layer reports a corresponding indication to the high layer, or the high layer is notified through an indication of random access failure.
It should be noted that, in the embodiment of the present invention, the state of the operation of recovering from the failure of the bottom layer detection beam of the user equipment is detected; and after the high layer of the user equipment determines the state of the beam failure recovery operation, controlling a radio link failure timer reported in advance according to the state of the beam failure recovery operation.
The bottom layer of the ue may be a physical layer or a Media Access Control (MAC) layer;
the higher layer of the user equipment may be RRC (Radio Resource Control).
Optionally, the higher layer of the user equipment determines the state of the beam failure recovery operation according to the following manner:
Mode 1: when the bottom layer of the user equipment detects that the state of the beam failure recovery operation changes, reporting indication information representing the state of the beam failure recovery operation to the high layer of the user equipment; and the higher layer of the user equipment determines the state of the beam failure recovery operation according to the received indication information.
It should be noted that, the bottom layer of the user equipment detects the state of the beam failure recovery operation, and may report the state of the beam failure recovery operation to be reported to the high layer when the state of the beam failure recovery operation changes correspondingly according to a predetermined convention; for the state of the other beam failure recovery operation except the appointed state, the state can not be reported to the high layer. For example, it is agreed in advance to report when the beam failure recovery operation fails, and when the bottom layer of the user equipment detects that the state of the beam failure recovery operation is the beam failure recovery operation failure, the bottom layer reports to the high layer; and when the bottom layer of the user equipment detects that the state of the beam failure recovery operation is the beam failure recovery operation success, the user equipment does not need to report the state to the high layer.
For example, when detecting that a beam failure recovery operation is started, a bottom layer of the user equipment reports instruction information of starting the beam failure recovery operation to a high layer of the user equipment; the high-level of the user equipment stores the state of starting the beam failure recovery operation;
If the bottom layer of the user equipment detects that the beam failure recovery operation fails, reporting the indication information of the beam failure recovery operation failure or the indication information of the random access failure to the high layer of the user equipment; setting the stored state of the beam failure recovery operation as operation failure by a high layer of the user equipment;
if the bottom layer of the user equipment detects that the beam failure recovery operation is successful, reporting indication information of the beam failure recovery operation success to the high layer of the user equipment; the high level of the user equipment sets the state of the stored beam failure recovery operation as successful operation;
mode 2: after receiving query information sent by a high layer, a bottom layer of the user equipment reports indication information representing the state of beam failure recovery operation to the high layer of the user equipment; and the higher layer of the user equipment determines the state of the beam failure recovery operation according to the received indication information.
It should be noted that, the higher layer of the user equipment may periodically send query information to the lower layer; or, the higher layer of the user equipment sends the query information to the bottom layer when the state of the beam failure recovery operation needs to be determined. The following description will be made separately.
1) And the upper layer of the user equipment periodically sends inquiry information to the bottom layer.
The high layer of the user equipment periodically sends query information to the bottom layer, and the bottom layer reports the state of the current beam failure recovery operation to the high layer in an indication information mode after receiving the query information; and after receiving the indication information, the high layer of the user equipment stores the state of the beam failure recovery operation.
2) And the upper layer of the user equipment sends inquiry information to the bottom layer when the state of the beam failure recovery operation needs to be determined.
When the state of the beam failure recovery operation needs to be judged, the high layer of the user equipment sends query information to the bottom layer; and the higher layer of the user equipment stores the state of the beam failure recovery operation after receiving the indication information.
For example, after determining that the radio link failure timer reported in advance is overtime, the higher layer of the user equipment needs to determine the state of the beam failure recovery operation and send query information to the lower layer.
For example, the high layer of the user equipment sends query information to the bottom layer, and if the bottom layer of the user equipment determines that the beam failure recovery operation is currently performed, the high layer of the user equipment reports indication information that the beam failure recovery operation is currently performed; the high-level of the user equipment stores the ongoing state of the beam failure recovery operation;
It should be noted that the above two types of state manners for determining the beam failure recovery operation by the higher layer of the ue are not either; in particular, the two methods may be combined.
Specifically, when the bottom layer of the user equipment determines that the beam failure recovery operation is successful, reporting indication information of the success of the beam failure recovery operation to the high layer;
when determining that the beam failure recovery operation fails at a bottom layer of the user equipment, reporting instruction information of the beam failure recovery operation failure or random access failure instruction information to a high layer;
after the upper layer of the user equipment determines that the radio link failure timer reported in advance is overtime, sending query information to the bottom layer of the user equipment, and reporting the state of the beam failure recovery operation to the upper layer by the bottom layer of the user equipment; the state that the bottom layer of the user equipment reports the beam failure recovery operation to the high layer comprises that the beam failure recovery operation is in progress and the beam failure recovery operation is not in progress.
Optionally, in the embodiment of the present invention, the user equipment controls the radio link failure timer reported in advance according to the state of the radio link failure timer reported in advance and the state of the beam failure recovery operation;
And the user equipment determines the state of the wireless link according to the state of the wireless link failure timer reported in advance and/or the state of the beam failure recovery operation.
The following describes the states of different early reporting radio link failure timers and the state of beam failure recovery operation, respectively.
Firstly, reporting that a radio link failure timer is running in advance, wherein the state of the beam failure recovery operation is beam failure recovery operation failure.
1. The user equipment controls the radio link failure timer reported in advance by adopting the following modes:
and when the report-ahead radio link failure timer is running, if the state of the beam failure recovery operation is the beam failure recovery operation failure, the user equipment closes the report-ahead radio link failure timer.
In implementation, when the report-ahead radio link failure timer is running, if the bottom layer of the user equipment detects that the beam failure recovery operation fails, the bottom layer of the user equipment reports indication information indicating that the beam failure recovery operation fails to the upper layer of the user equipment, or the indication information can also be indication information of random access failure, and the user equipment closes the report-ahead radio link failure timer.
2. The user equipment determines the radio link state in the following way:
when a radio link failure timer is reported to be running in advance, if the state of the beam failure recovery operation is the beam failure recovery operation failure, the user equipment determines that the radio link failure occurs, and triggers a corresponding link failure behavior according to the failed radio link; the link failure behavior is an RRC connection reestablishment request process or a process of reporting radio link failure related information to a network side.
It should be noted that, after the beam failure recovery operation fails, the bottom layer of the ue does not perform any further beam failure recovery operation, so that after the beam failure recovery operation fails, it can determine that a radio link failure occurs, and without continuing to wait for the radio link failure timer reported in advance to be overtime, the corresponding link failure behavior can be triggered, and the radio link failure timer reported in advance is closed.
As shown in fig. 2, when the radio link failure report in advance timer is running and the beam failure recovery operation state is the beam failure recovery operation failure, the ue controls the overall flowchart of the radio link failure report in advance timer.
The condition of starting the radio link failure timer reported in advance is taken as an example to determine that the quality of the measurement signal meets the condition of triggering the measurement report to report.
Step 201, the user equipment determines that the quality of the measurement signal meets the condition of triggering the report of the measurement report;
the configuration of the measurement report comprises measurement configuration of a network side for starting a function of reporting a radio link failure timer in advance.
Step 202, the user equipment starts a radio link failure report timer in advance.
Step 203, in the process of reporting in advance that the radio link failure timer is running, the bottom layer of the user equipment detects that the beam failure recovery operation fails, and reports indication information indicating that the beam failure recovery operation fails to the top layer of the user equipment, or the indication information can also be indication information of random access failure.
Step 204, the user equipment determines that the state of the beam failure recovery operation is a beam failure recovery operation failure.
Step 205, the ue closes the radio link failure report timer.
Step 206, the user equipment determines that a radio link failure occurs, and triggers a corresponding link failure behavior according to the failed radio link;
The link failure behavior is an RRC connection reestablishment request process or a process of reporting radio link failure related information to a network side.
It should be noted that, the sequence between step 205 and step 206 is not distinguished.
Example 1:
taking a timer for reporting a radio link failure in advance as a timer T312 as an example;
step 1, when a timer T312 is running, receiving beam failure recovery failure indication information or random access failure indication information reported by a bottom layer of user equipment;
step 2, closing the timer T312;
and step 3, determining the Radio Link Failure and triggering an RLF (Radio Link Failure) process.
As shown in fig. 3, when the report radio link failure timer is running and the beam failure recovery operation state is the beam failure recovery operation failure, the ue controls another overall flowchart of the report radio link failure timer.
The radio link failure monitoring timer is started by the user equipment, and the condition that the user equipment determines that the quality of the measurement signal meets the condition of triggering the report of the measurement report is taken as the condition of starting the radio link failure timer reported in advance.
Step 301, the user equipment starts a radio link failure monitoring timer;
the radio link failure monitoring timer is started based on the out-of-step indication reported by the bottom layer.
Step 302, the user equipment determines that the quality of the measurement signal meets the condition of triggering the report of the measurement report;
the configuration of the measurement report comprises measurement configuration of a network side for starting a function of reporting a radio link failure timer in advance.
Step 303, the ue starts a radio link failure report timer.
Step 304, in the process of reporting in advance that the radio link failure timer is running, the bottom layer of the user equipment detects that the beam failure recovery operation fails, and reports indication information indicating that the beam failure recovery operation fails to the top layer of the user equipment, or the indication information can also be indication information of random access failure.
Step 305, the user equipment determines that the state of the beam failure recovery operation is a beam failure recovery operation failure.
Step 306, the user equipment closes the radio link failure timer reported in advance.
Step 307, the user equipment determines that a radio link failure occurs, and triggers a corresponding link failure behavior according to the failed radio link;
The link failure behavior is an RRC connection reestablishment request process or a process of reporting radio link failure related information to a network side.
It should be noted that, the sequence between step 306 and step 307 is not distinguished.
Example 2:
taking a radio link failure monitoring timer as a timer T310, and taking a radio link failure timer reported in advance as a timer T312 as an example;
step 1, starting a timer T310;
step 2, when the quality of the measurement signal meets the condition of triggering the report of the measurement report, starting a timer T312;
step 3, when the timer T312 is running, receiving the instruction information of the failure of the beam failure recovery or the instruction information of the failure of the random access reported by the bottom layer of the user equipment;
step 4, closing the timer T312;
and step 5, determining the Radio Link Failure, and triggering an RLF (Radio Link Failure) process.
And reporting that the radio link failure timer is running in advance, wherein the state of the beam failure recovery operation is that the beam failure recovery operation is successful.
The user equipment controls the radio link failure timer reported in advance by adopting the following modes:
and if the state of the beam failure recovery operation is that the beam failure recovery operation is successful, the user equipment restarts, prolongs or closes the radio link failure timer reported in advance.
After the beam failure recovery operation is successful, the usable beam exists on the bottom layer of the user equipment, and the wireless link is recovered to be normal; at this time, if the radio link failure timer reported in advance is about to time out, although the radio link is recovered to normal, there is not enough time to receive the continuous preset number of synchronous instructions or receive the switching command, so that the radio link failure timer reported in advance is overtime to trigger the corresponding link failure behavior. Therefore, after the bottom layer of the user equipment determines that the beam failure recovery operation is successful, the radio link failure judgment is delayed by restarting, prolonging or closing the mode of reporting the radio link failure timer in advance.
As shown in fig. 4, when the radio link failure report in advance timer is running and the beam failure recovery operation is in a state of successful beam failure recovery operation, the ue controls the overall flowchart of the radio link failure report in advance timer.
The condition of starting the radio link failure timer reported in advance is taken as an example to determine that the quality of the measurement signal meets the condition of triggering the measurement report to report.
Step 401, the user equipment determines that the quality of the measurement signal meets the condition of triggering the report of the measurement report;
The configuration of the measurement report comprises measurement configuration of a network side for starting a function of reporting a radio link failure timer in advance.
Step 402, the user equipment starts a radio link failure timer reported in advance.
Step 403, in the process of reporting in advance that the radio link failure timer is running, the high layer of the user equipment receives the indication information which is reported by the bottom layer and represents that the beam failure recovery operation is successful.
Step 404, the ue determines that the beam failure recovery operation is successful.
Step 405, the user equipment restarts, prolongs or closes the early reporting radio link failure timer.
Example 3:
taking a timer for reporting a radio link failure in advance as a timer T312 as an example;
step 1, when a timer T312 is running, receiving indication information of successful beam failure recovery reported by a bottom layer of user equipment;
step 2, closing the timer T312;
step 3, continuously counting and receiving the synchronous indication;
and step 4, triggering and starting a timer T312 according to the measurement report.
Example 4:
taking a timer for reporting a radio link failure in advance as a timer T312 as an example;
step 1, when a timer T312 is running, receiving indication information of successful beam failure recovery reported by a bottom layer of user equipment;
Step 2, restarting or extending the timer T312;
and step 3, continuously counting and receiving the synchronous indication.
And thirdly, reporting the overtime of the radio link failure timer in advance, and the high layer of the user equipment cannot acquire the state of the bottom layer beam failure recovery operation.
The user equipment determines the state of the radio link according to the state of the radio link failure timer reported in advance:
after the report-ahead radio link failure timer is overtime, and the high layer of the user equipment cannot know the state of the bottom layer beam failure recovery operation, the user equipment determines that the radio link failure occurs, and triggers a corresponding link failure behavior according to the failed radio link, wherein the link failure behavior is an RRC connection reestablishment request process or a process of reporting radio link failure related information to a network side.
An alternative embodiment is:
after the user equipment determines that the radio link failure timer reported in advance is overtime, the high layer of the user equipment inquires the state of the beam failure recovery operation detected by the bottom layer, if the high layer of the user equipment cannot know the state of the beam failure recovery operation of the bottom layer, the user equipment determines that the radio link failure occurs or does not have a mechanism for inquiring the beam failure recovery operation state from the high layer to the bottom layer, the user equipment determines that the radio link failure occurs, and triggers a corresponding link failure behavior according to the failed radio link.
It should be noted that the upper layer of the ue cannot know the state of the bottom-layer beam failure recovery operation, and does not mean that the bottom layer of the ue cannot perform the beam failure recovery operation; when the high layer of the user equipment cannot know the state of the bottom layer beam failure recovery operation, even if the bottom layer of the user equipment is performing the beam failure recovery operation or the beam failure recovery operation is successful, the user equipment determines that the radio link failure occurs after the radio link failure timer is reported in advance and times out due to the fact that the high layer of the user equipment cannot know, and triggers a corresponding link failure behavior according to the failed radio link.
As shown in fig. 5, when the early reporting radio link failure timer is overtime and the higher layer of the ue cannot know the state of the bottom-layer beam failure recovery operation, the ue controls the overall flowchart of the early reporting radio link failure timer.
The condition of starting the radio link failure timer reported in advance is taken as an example to determine that the quality of the measurement signal meets the condition of triggering the measurement report to report.
Step 501, the user equipment determines that the quality of the measurement signal meets the condition of triggering the report of the measurement report;
The configuration of the measurement report comprises measurement configuration of a network side for starting a function of reporting a radio link failure timer in advance.
Step 502, the user equipment starts a radio link failure timer reported in advance.
Step 503, after the radio link failure timer reported in advance times out, the high layer of the user equipment determines that the state of the bottom layer beam failure recovery operation cannot be known.
Step 504, the user equipment closes the radio link failure timer reported in advance.
Step 505, the user equipment determines that a radio link failure occurs, and triggers a corresponding link failure behavior according to the failed radio link;
the link failure behavior is an RRC connection reestablishment request process or a process of reporting radio link failure related information to a network side.
It should be noted that, the order of step 504 and step 505 is not distinguished.
Example 5:
taking a timer for reporting a radio link failure in advance as a timer T312 as an example;
step 1, after a timer T312 is overtime, determining whether the high layer cannot sense whether the bottom layer is performing the beam failure recovery;
step 2, closing the timer T312;
and 3, determining that the radio link fails and triggering the RLF process.
And fourthly, reporting the overtime of the radio link failure timer in advance, wherein the state of the beam failure recovery operation is not carried out.
Optionally, after determining that the report radio link failure timer expires in advance, the higher layer of the user equipment queries a state of a beam failure recovery operation detected by the lower layer, and the lower layer of the user equipment reports the beam failure recovery operation to the higher layer without performing the beam failure recovery operation;
it should be noted that after determining that the radio link failure timer reported in advance is overtime, the user equipment needs to immediately query the state of the beam failure recovery operation.
The user equipment determines the radio link state in the following way:
after the report-ahead radio link failure timer is overtime and the beam failure recovery operation is not performed, the user equipment determines that a radio link failure occurs and triggers a corresponding link failure behavior according to the failed radio link, wherein the link failure behavior is an RRC connection reestablishment request process or a process of reporting radio link failure related information to a network side.
As shown in fig. 6, when the radio link failure report timer expires in advance, and the high layer of the ue knows that the beam failure recovery operation is not performed in the bottom layer, the ue controls the overall flowchart of the radio link failure report timer in advance.
The condition of starting the radio link failure timer reported in advance is taken as an example to determine that the quality of the measurement signal meets the condition of triggering the measurement report to report.
Step 601, the user equipment determines that the quality of the measurement signal meets the condition of triggering the report of the measurement report;
the configuration of the measurement report comprises measurement configuration of a network side for starting a function of reporting a radio link failure timer in advance.
Step 602, the ue starts a radio link failure report timer.
Step 603, after the radio link failure timer reported in advance times out, the high layer of the user equipment queries the state of the beam failure recovery operation detected by the bottom layer.
Step 604, if the beam failure recovery operation reported from the bottom layer to the upper layer by the user equipment is not performed, the user equipment determines that a radio link failure occurs, and triggers a corresponding link failure behavior according to the failed radio link;
the link failure behavior is an RRC connection reestablishment request process or a process of reporting radio link failure related information to a network side.
Example 6:
taking a timer for reporting a radio link failure in advance as a timer T312 as an example;
step 1, after a timer T312 is overtime, the high layer does not receive beam failure recovery success or failure indication information or random access failure indication information reported by the bottom layer;
step 2, the high layer sends a query message to the bottom layer to inform the bottom layer to start RLF judgment and obtain the state of the bottom layer beam failure recovery operation;
Step 3, the bottom layer receives the inquiry information of the high layer and reports the state of the beam failure recovery operation to the high layer;
step 4, the beam failure recovery reported by the bottom layer is received by the high layer without processing;
and 5, determining that the radio link fails, and triggering an RLF process.
And fifthly, reporting the overtime of the radio link failure timer in advance, wherein the state of the beam failure recovery operation is in progress.
Optionally, after determining that the report radio link failure timer expires in advance, the higher layer of the user equipment queries a state of a beam failure recovery operation detected by the lower layer, and the lower layer of the user equipment reports the beam failure recovery operation to the higher layer;
it should be noted that after determining that the radio link failure timer reported in advance is overtime, the user equipment needs to immediately query the state of the beam failure recovery operation.
The user equipment controls the radio link failure timer reported in advance by adopting the following modes:
after the radio link failure timer reported in advance is overtime, if the beam failure recovery operation state is in progress, the user equipment restarts the radio link failure timer reported in advance, or the user equipment prolongs the duration of the radio link failure timer reported in advance.
After the radio link failure report timer is reported in advance and is overtime, if the state of the beam failure recovery operation is determined to be in progress, the radio link failure judgment is delayed in a mode of restarting the radio link failure report timer in advance or prolonging the time length of the radio link failure report timer in advance, and the result of the beam failure recovery operation is waited; if the beam failure recovery operation is successful, unnecessary delay and signaling overhead caused by the radio link failure judgment can be avoided.
As shown in fig. 7, when the early reporting radio link failure timer expires and the higher layer of the ue knows that the lower layer is performing the beam failure recovery operation, the ue controls the overall flowchart of the early reporting radio link failure timer.
The condition of starting the radio link failure timer reported in advance is taken as an example to determine that the quality of the measurement signal meets the condition of triggering the measurement report to report.
Step 701, the user equipment determines that the quality of the measurement signal meets the condition of triggering the report of the measurement report;
the configuration of the measurement report comprises measurement configuration of a network side for starting a function of reporting a radio link failure timer in advance.
Step 702, the ue starts a radio link failure report timer.
Step 703, after the radio link failure timer reported in advance times out, the high layer of the user equipment queries the state of the beam failure recovery operation detected by the bottom layer.
Step 704, if the beam failure recovery operation is ongoing, the ue restarts or prolongs the timer for reporting the radio link failure in advance.
Example 7:
taking a timer for reporting a radio link failure in advance as a timer T312 as an example;
step 1, after a timer T312 is overtime, the high layer does not receive beam failure recovery success or failure indication information or random access failure indication information reported by the bottom layer;
step 2, the high layer sends a query message to the bottom layer to inform the bottom layer to start RLF judgment and obtain the state of the bottom layer beam failure recovery operation;
step 3, the bottom layer receives the inquiry information of the high layer and reports the state of the beam failure recovery operation to the high layer;
step 4, the high-level receives the beam failure recovery reported by the bottom layer in progress;
step 5, restart or extend timer T312.
Optionally, in the operation process of the early reporting radio link failure timer, if the RLM threshold changes, the early reporting radio link failure timer is restarted.
Because RLM synchronous and desynchronizing reporting thresholds can be set as different threshold pairs according to the service types, wherein the different threshold pairs have different requirements on synchronous and desynchronizing in strict degree, and more strict thresholds can be configured with high requirements on service quality; in the operation process of the early reporting radio link failure timer, if the RLM threshold is determined to be changed, for example, the RLM threshold is reconfigured from the high threshold to the low threshold, or the RLM threshold is reconfigured from the low threshold to the high threshold, the user equipment restarts the early reporting radio link failure timer to delay the RLF decision.
The RLM threshold is a value specified by a protocol or a value pre-configured by a network side.
In addition, after the user equipment starts the radio link failure timer for early reporting, if the user equipment determines that the type of the RLM measurement reference signal changes, the state of the radio link failure timer for early reporting is kept unchanged.
It should be noted that, in the operation process of the radio link failure timer reported in advance, if the type of the RLM measurement reference signal changes, the state of the radio link failure timer reported in advance is not affected.
For example, when the type of the reference signal for RLM measurement is changed from SSB to CSI-RS or from CSI-RS to SSB, because both reference signals can reflect the current signal quality to some extent, if the type of the reference signal for RLM measurement is changed, that is, when the type of the reference signal for RLM measurement is changed from SSB to CSI-RS or from CSI-RS to SSB, the state of the radio link failure timer reported in advance is not affected.
