For a better understanding of aspects of embodiments of the present application, related terms and concepts that may be related to embodiments of the present application are described below.

RLM: the RLM at the cell level IS to monitor the downlink channel quality of the serving cell, the physical layer evaluates the radio link quality for a specified time and compares with a Qin/Qout threshold, if all RLM-RS (reference signal) evaluations are below Qout, the physical layer reports out-of-sync (OOS) indication to the upper layer, if at least one RLM-RS evaluation IS above Qin, reports in-syc, IS indication to the upper layer. Qout is defined as the level (RML-RS) at which the downlink radio link cannot be reliably received, and the threshold corresponds to the block error rate (BLERout, 10%) at OOS; qin is defined as the level (RML-RS) at which the downlink radio link can be received with a much higher reliability than Qout, the threshold corresponds to the block error rate (BLERin, 2%) at in (in sync).

The BLERout, BLERin parameter is determined by detecting the BLER of the physical downlink control signal (physical downlink control channel, PDCCH) of the corresponding format (DCI format 1-0) for the corresponding transmission parameter. The BLER value is configured by a higher layer parameter (RRC). If not configured, the UE uses a default value where the Qout threshold corresponds to a BLER of 10% and the Qin threshold corresponds to a BLER of 2%.

RLM can only be performed on the primary cell (PCell) and the primary secondary cell (PScell), and only on the active bandwidth part (active bandwidth part, active bwp) of the activation of the SPcell (pcell+pscell). Format 1_0 is used for Cell physical downlink shared channel (physical downlink share channel, PDSCH) scheduling, downlink control information (Downlink Control Information, DCI) Format 1_0 cyclic redundancy check (Cyclic Redundancy Check, CRC) is scrambled by Cell radio network temporary identity (Cell-Radio Network Temporary Identifier, C-RNTI).

The UE monitors up to Nrlm RLM-RS resources within the active bwp according to the maximum number of SSBs in the field (Lmax, lmax=4/8/64). A maximum of Nlr-RLM RLM-RSs may be configured for the UE for Link Recovery (LR) and RLM.

LR: including Beam Failure Detection (BFD) and Beam Failure Recovery (BFR). The UE can use the maximum Nrlm RLM RSs from Nlr-RLM RLM RSs for RLM; the UE may use up to 2 RSs from Nlr-rlm RLMRSs for the link recovery procedure (bidirectional forwarding detection, bidirectional Forwarding Dection, BFD).

Discontinuous reception (Discontinuous Reception, DRX): packet-based data streams are typically bursty, with data transmitted for a period of time, but without data transmitted for a longer period of time following. When there is no data transmission, the power consumption can be reduced by stopping receiving the PDCCH (at this time, stopping the PDCCH blind detection), thereby improving the battery use time. This is the origin of DRX. The indication period of the RLM measurement is related to the DRX period.

At present, in the prior art, the triggering condition and the loosening method of the RLM measurement are considered, and the RLM measurement is less in the discussion of the loosening recovery, so that after the RLM measurement is relaxed, the measurement state cannot be adjusted timely, and the robustness of the link cannot be ensured and the channel information cannot be captured timely.

In view of the foregoing, embodiments of the present application provide a measurement status adjustment method based on RLM, and the detailed description is given below with reference to the accompanying drawings.

Referring to fig. 2a, fig. 2a is a flowchart of a measurement status adjustment method based on RLM for radio link monitoring according to an embodiment of the present application, and as shown in the drawing, the method includes:

step 201, the network device sends reference resources to the terminal;

in step 202, the terminal receives a reference resource from the network device.

The reference resource may include "RS (reference signal) configured as RLM-RS resource" on the UE monitoring SPcell, where the configured RLM-RS resource may be a synchronization signal (synchronization signal, SS)/broadcast channel (physical broadcastchannel, PBCH) block (SSB), a channel state information reference signal (Channel State Information Reference Signal, CSI-RS), or a mixture of SSB and CSI-RS. The reference resource may also include a reference signal for the terminal to monitor for channel conditions.

And step 203, acquiring the measurement result of the RLM and the monitoring result of the channel state according to the reference resource.

When the channel state change is determined, the measurement result of the RLM may be an indication that the terminal reports to an upper layer. As shown in fig. 2b, fig. 2b is a schematic diagram of an evaluation period provided by the embodiment of the present application, where RLM-RS reference resources may be SSB, CSI-RS, or a combination thereof, and for each RS, the UE processes the RS to obtain radio link quality, and the metric may be reference signal received power (Reference Signal Receiving Power, RSRP)/reference signal received quality (Reference Signal Receiving Quality, RSRQ)/signal-to-noise ratio (Signal to Noise Ratio, SNR). The evaluation period IS different according to the quality of the OOS/IS evaluation according to whether the RS IS SSB or CSI-RS. The quality of the RS is compared to two thresholds Qout and Qin, wherein the Qout, qin values of the SSB and CSI-RS are also different. Based on the comparison results of all RSs in the RLM, the physical layer may send an L1 indication to the higher layer to indicate whether it IS OOS or IS, where the physical layer may obtain a comparison result once every indication period. In an evaluation period, the terminal obtains a measurement result according to the reference resource sent by the network device after each indication period. The monitoring result is used for indicating whether the channel state is changed, the network equipment sends a reference signal for channel monitoring to the terminal, and the terminal acquires the channel state according to the reference signal, wherein the channel state comprises channel quality, strength and the like.

And step 204, adjusting the measurement state of the RLM according to the measurement result of the RLM under the condition that the monitoring result is the channel state change.

Wherein the channel state change may be a channel quality degradation or the like. The measurement state of RLM may be two measurement states, measurement relaxation and dense measurement, when the UE triggers measurement relaxation according to channel state information or user speed, for example, for a UE with a particularly slow or stationary user movement, the channel state changes very slowly, and then it is not necessary to make RLM measurements frequently. The channel state can be monitored and captured according to the reference signal sent by the network device, and if the channel state is monitored to be changed, whether the current measurement state needs to be restored to dense measurement can be determined according to the measurement result of the RLM.

In this example, the electronic device sends a reference resource to the terminal, and the terminal obtains a measurement result of the RLM and a monitoring result of the channel state according to the reference resource, and adjusts the measurement state of the RLM according to the measurement result of the RLM when the monitoring result is that the channel state changes. Thus, when the channel state changes, the terminal has the capability of timely adjusting the measurement state of the RLM so as to ensure the robustness of the link.

In one possible example, the adjusting the measurement state of the RLM according to the measurement result of the RLM includes: the measurement result of the RLM is a measurement result in an evaluation period of the RLM corresponding to the channel state change.

The terminal has one evaluation period when performing RLM measurement, the evaluation period includes an indication period, and in the one indication period, the terminal obtains a measurement result and reports the measurement result to a higher layer, so that a plurality of measurement results can be obtained in one evaluation period, and an OOS or IS indication IS reported to the higher layer according to the plurality of measurement results. Fig. 2c is a schematic diagram of an evaluation process provided in the embodiment of the present application, and is not DRX: t_indication_interval=max (10, t_rlm-RS), DRX: if the DRX cycle length is less than or equal to 320ms, the indication cycle is max (10, 1.5 times DRX_cycle_length,1.5 times T_RLM-RS); if the DRX cycle length is greater than 320ms, the indication period is the DRX cycle length. N310 receives IS and resets, receive OOS N310 count up, in receiving N310 OOS indications that report continuously, start timer T310 at the same time (N310 times are up); if N311 IS indications continuously reported are received in the T310 time period, the UE stops T310 and enters a normal evaluation period; if N311 IS indications are not received for the period of T310, the UE stops T310 and declares a radio link failure (radio link failure, RLF). The corresponding evaluation period when the channel state changes may be determined first, then all measurement results in the evaluation period are acquired, and then the measurement results are judged to determine whether the measurement state of the RLM needs to be changed.

In this example, whether the channel state needs to be changed is determined according to the corresponding measurement result when the channel state is changed, so that whether the measurement state of the RLM needs to be adjusted can be evaluated more accurately, and the evaluation speed can be increased.

In one possible example, the adjusting the measurement state of the RLM according to the measurement result of the RLM includes: acquiring N measurement results of the RLM; and when the measurement results of the N RLMs meet a first preset condition, adjusting the measurement state of the RLMs.

When the measurement state of the current RLM is measurement relaxation, if a channel state change is monitored, N measurement results of the RLM in an evaluation period corresponding to the channel state change can be obtained at this time, the obtained N measurement results of the RLM are analyzed, the current measurement state of the measurement RLM can be adjusted to be dense measurement if a first preset condition is met, and the measurement state of the RLM is not adjusted if the first preset condition is not met. The first preset condition may be that all measurement results of the N RLMs are OOS or that measurement results of M RLMs in the N measurement results of the N RLMs are OOS, where the measurement results of the N RLMs may be measurement results of N RLMs in the evaluation period obtained randomly or measurement results of N RLMs in the evaluation period continuously.

In this example, the measurement results of the N RLMs are compared with the first preset condition, and when the measurement results of the N RLMs meet the first preset condition, the measurement states of the RLMs are adjusted, so that whether the measurement states of the RLMs need to be adjusted can be evaluated more accurately, and when the channel state changes, the terminal has the capability of adjusting the measurement states of the RLMs in time, so as to ensure the robustness of the link.

In one possible example, the first preset condition is: the measurement results of the N RLMs are all asynchronous, wherein the measurement results of the N RLMs are measurement results of N continuous RLMs.

Where the UE triggers a measurement relaxation based on channel state information or user speed, e.g. for a UE that is particularly slow to move or stationary, the channel state changes very slowly, and then it is not necessary to make RLM measurements frequently. After the RLM measurement is relaxed, the channel state of the UE changes suddenly, the network configures a threshold N in advance, the channel state is bad, the RS is measured in the evaluation period, the RS is reported once in the indication period, and if OOS are reported, and the measurement result is continuous N OOS, the UE resumes intensive monitoring.

In this example, if the measurement results of N consecutive RLMs are OOS, the measurement state of the RLM may be adjusted, so that whether the measurement state of the RLM needs to be adjusted may be evaluated more accurately, so that when the channel state changes, the terminal has the ability to adjust the measurement state of the RLM in time, so as to ensure the robustness of the link.

In one possible example, the first preset condition is: among the N RLM measurement results, M RLM measurement results are unsynchronized.

The measurement results of the M RLMs may be any one of the measurement results of the N RLMs, or may be measurement results of consecutive M RLMs of the measurement results of the N RLMs. When the UE triggers measurement relaxation according to channel state information or user speed, after the RLM measurement relaxation is carried out, the channel state of the UE changes suddenly, a threshold M and a threshold N are configured in advance by the network, the channel state is bad, the RS is measured in an evaluation period, the RS is reported once in an indication period, and if the OOS is reported, and the measurement result is M OOS in N results, the UE resumes intensive monitoring.

In this example, when the measurement results of M RLMs are OOS, the measurement states of the RLMs are adjusted, so that whether the measurement states of the RLMs need to be adjusted can be evaluated more accurately, and when the channel state changes, the terminal has the ability to adjust the measurement states of the RLMs in time, so as to ensure the link robustness.

In one possible example, the adjusting the measurement state of the RLM according to the measurement result of the RLM includes: and adjusting the measurement state to be dense measurement.

And when the measurement state of the current terminal is measurement relaxation, and the acquired measurement result of the RLM meets the preset condition, the measurement state of the RLM can be adjusted to be dense measurement.

In this example, the measurement state of RLM is adjusted from measurement relaxation to dense measurement, so that the robustness of the link and the timeliness of obtaining the channel information can be ensured.

In one possible example, in a case where the listening result is the channel state change, the method further includes: acquiring the current signal strength of a serving cell; and when the current signal strength meets a second preset condition, adjusting the measurement state of the RLM.

The terminal can judge the channel state according to the reference resource sent by the network device, so as to determine the current signal strength of the serving cell where the terminal is located, and compare the current signal strength of the serving cell with a second preset condition to determine whether to adjust the measurement state of the RLM.

In this example, whether the measurement state of the RLM needs to be adjusted is determined according to the signal strength of the serving cell, so that whether the measurement state of the RLM needs to be adjusted can be evaluated more accurately, and when the channel state changes, the terminal has the capability of adjusting the measurement state of the RLM in time, so as to ensure the robustness of the link.

In one possible example, the current signal strength is a rate of change of the channel state, and the second preset condition is: the rate of change of the channel state is greater than a first threshold.

The rate of change of the channel state may be determined according to SNR or RSRP.

In this example, whether the measurement state of the RLM needs to be adjusted is determined according to the signal strength only when the channel state change rate is greater than the first threshold, so that whether the measurement state of the RLM needs to be adjusted can be evaluated more accurately, and when the channel state changes, the terminal has the capability of adjusting the measurement state of the RLM in time, so as to ensure the robustness of the link.

In one possible example, the second preset condition is: the difference between the current signal strength and the reference signal strength is greater than a second threshold.

When the UE triggers measurement relaxation according to the channel state information or the user speed, after RLM measurement relaxation is performed, the channel state of the UE changes suddenly, the UE serving cell itself has a reference signal strength, and the reference signal strength is compared with the current signal strength of the serving cell, if the difference between the current signal strength and the reference signal strength is greater than a second threshold, it is indicated that the current channel change is relatively large, the current monitoring is restored, otherwise, the current RLM measurement relaxation state is maintained. That is (serving cell current signal strength value Srxlev-serving cell reference signal strength Srxlev) _Ref )>Second threshold S _SearchDeltaP . Wherein the second threshold value may be equal to the first threshold valueIn the LTE (long term evolution) system, qrxlevmeas is the power value RSRP of the reference signal of the cell measured by the UE, qrxlevmin is the corresponding minimum value, both parameters are broadcasted in the system message of the serving cell, qrxlevminoffset is the corresponding offset, and the method is only applied to the cell in the PLMN with high priority evaluated by the UE residing in the visited public land mobile network (Public Land Mobile Network, PLMN), pcomponsite is a factor considering the difference between the actual maximum transmission power (Maximum RF output power, expressed by the pprowery class) of the UE and the allowed maximum transmission power (Maximum TX power level, expressed by pemax_h) of the cell, and pcomponsite=max (pemax_h-pproviss, 0).

In this example, the measurement state of the RLM is adjusted only when the difference between the current signal strength and the reference signal strength is greater than the preset threshold, so that whether the measurement state of the RLM needs to be adjusted can be evaluated more accurately, and when the channel state changes, the terminal has the ability to adjust the measurement state of the RLM in time, so as to ensure the robustness of the link.

In one possible example, in a case where the listening result is the channel state change, the method further includes: receiving indication information from a network layer; and adjusting the measurement state of the RLM according to the indication information.

When the UE triggers measurement relaxation according to channel state information or user speed, after RLM measurement relaxation is performed, the channel state of the UE changes suddenly, and the indication of the network device may be directly recovered to dense monitoring, where the indication information may be a DCI (scheduling DCI, non-scheduling DCI) indication and a medium access control layer control element (Media Access ControlControl Element, MAC CE) indication.

In this example, whether the measurement state of the RLM needs to be adjusted can be determined directly according to the received indication from the network device, so that when the channel state changes, the terminal can adjust the measurement state of the RLM in time, so as to ensure the robustness of the link.

In one possible example, the adjusting the measurement state of the RLM according to the measurement result of the RLM includes: acquiring a third threshold value set by a network layer; acquiring an accumulated value according to the measurement result of the RLM and the third threshold value; and when the accumulated value meets a third preset condition, adjusting the measurement state of the RLM.

Wherein the RLM measurement is obtained by comparing the acquired radio link quality with a third threshold, and the RLM measurement may be used to indicate whether the current channel state is greater than or less than the third threshold, where the third threshold may be different from the Qin/Qout threshold, for example, the third threshold is less than the Qout threshold. Accumulating the measurement results of the RLM according to a preset rule to obtain an accumulated value, comparing the accumulated value with a third preset condition, adjusting the measurement state of the RLM if the accumulated value meets the third preset condition, and not adjusting the measurement state of the RLM if the accumulated value does not meet the third preset condition.

In this example, the measurement result is obtained according to the third threshold, and the accumulated value is obtained according to the measurement result, and when the accumulated value meets the third preset condition, the measurement state of the RLM is adjusted, so that whether the measurement state of the RLM needs to be adjusted can be evaluated more accurately, and when the channel state changes, the terminal has the capability of adjusting the measurement state of the RLM in time, so as to ensure the robustness of the link.

In one possible example, the third preset condition is: the cumulative value is greater than K.

When the UE triggers measurement relaxation according to channel state information or user speed, after RLM measurement relaxation is performed, the channel state of the UE changes suddenly, the network configures a third threshold and a judgment threshold K in advance, and when the channel state is bad, the RS is measured in an evaluation period, and when the obtained accumulated value is greater than the judgment threshold K, dense monitoring is resumed.

In this example, the measurement state of the RLM is adjusted when the accumulated value is greater than the preset threshold, so that whether the measurement state of the RLM needs to be adjusted can be evaluated more accurately, and when the channel state changes, the terminal has the capability of adjusting the measurement state of the RLM in time, so as to ensure the robustness of the link.

In one possible example, the third preset condition is: and the accumulated value obtained according to the L measurement results of the RLM is greater than S.

When the UE triggers measurement relaxation according to the channel state information or the user speed, after RLM measurement relaxation is performed, the channel state of the UE changes suddenly, the network configures a third threshold and judgment thresholds L and S in advance, and when the channel state is bad, the RS is measured in the evaluation period, and when the cumulative value obtained according to the measurement results of the L RLMs is S, the dense monitoring is resumed.

In this example, when the cumulative value obtained according to the measurement results of the L RLMs is S, the measurement results of the RLMs may be adjusted, so that whether the measurement state of the RLMs needs to be adjusted may be evaluated more accurately, so that when the channel state changes, the terminal has the ability to adjust the measurement state of the RLMs in time, so as to ensure the robustness of the link.

In one possible example, the obtaining the accumulated value according to the measurement result of the RLM and the third threshold value includes: acquiring a current measurement result of the RLM, adding one to the accumulated value when the current measurement result of the RLM is not greater than the third threshold, and clearing the accumulated value when the current measurement result of the RLM is greater than the third threshold; determining the measurement result of the next RLM as the measurement result of the current RLM, and acquiring an accumulated value according to the measurement result of the current RLM and the third threshold; repeating the steps until the current measurement result of the RLM is the last measurement result of the RLM.

And when the accumulated K measurement results are smaller than the third threshold value, the intensive monitoring is restored. Or, the RS is measured in the evaluation period, if the current channel state measurement result is smaller than the second threshold, the current channel state measurement result is counted and is larger than the second threshold, and when S measurement results in the L results are smaller than the second threshold, namely the accumulated value is S, the intensive monitoring is restored. Or the RS is measured in the evaluation period, the current channel state measurement result is counted when being smaller than the second threshold and is larger than the second threshold, and when the continuous S measurement results in the L results are smaller than the second threshold, namely the accumulated value is S, the intensive monitoring is restored.

In a specific implementation, the acquiring the accumulated value according to the measurement result of the RLM and the third threshold value further includes: acquiring a current RLM measurement result, adding one to the accumulated value when the current RLM measurement result is not smaller than the third threshold value, and keeping the accumulated value unchanged when the current RLM measurement result is smaller than the third threshold value; determining the measurement result of the next RLM as the measurement result of the current RLM, and acquiring an accumulated value according to the measurement result of the current RLM and the third threshold; repeating the steps until the current measurement result of the RLM is the last measurement result of the RLM.

In this example, whether to accumulate is determined according to the channel state and the third threshold, so as to determine whether to adjust the measurement state of the RLM according to the obtained accumulated value, so that the measurement state of the RLM can be evaluated more accurately, and when the channel state changes, the terminal has the capability of adjusting the measurement state of the RLM in time, so as to ensure the robustness of the link.
