the embodiment of the invention provides a pilot frequency measurement relaxing method, which comprises the following steps: acquiring a signal measurement result of at least one pilot frequency point; and aiming at each pilot frequency point, adjusting the measurement period of the pilot frequency point or suspending the measurement of the pilot frequency point according to the signal measurement result of the pilot frequency point.
Compared with the prior art, the scheme of the embodiment can effectively reduce invalid measurement, and further reduce the power consumption of the UE.

Detailed Description
As a background, an invalid measurement is very easy to occur when the existing UE performs the inter-frequency measurement.
Currently, the third Generation Partnership Project (3rd Generation Partnership Project, 3GPP) is discussing the measurement relaxation problem when the UE operates in a power saving (power saving) mode. Specifically, under Radio Resource Control (RRC) IDLE state (IDLE) or INACTIVE state (INACTIVE), there are mainly three measurement relaxation methods:
firstly, the measurement period of each frequency point is prolonged. However, this method uniformly extends the measurement periods of all the pilot frequency points, and for the pilot frequency point with particularly low signal quality, the UE still needs to measure the pilot frequency point, and the problem of invalid measurement is not solved. Moreover, for the pilot frequency points with better signal quality, excessively prolonging the measurement period is not beneficial to timely mastering the signal quality change condition of the pilot frequency points.
And secondly, the measurement of all the pilot frequency points is closed on demand. Similar to the drawback of the first method, for the pilot frequency points with better signal quality, the method of directly turning off the measurement is obviously not suitable.
And thirdly, reducing the frequency points of measurement. However, this method cannot reduce the power consumption of the UE, because the reduction of the number of frequency points will shorten the measurement period of other pilot frequency points, which means that other pilot frequency points will measure more frequently.
Therefore, the prior art cannot effectively solve the problem of invalid measurement during pilot frequency measurement.
In order to solve the above technical problem, an embodiment of the present invention provides a pilot frequency measurement relaxing method, including: acquiring a signal measurement result of at least one pilot frequency point; and aiming at each pilot frequency point, adjusting the measurement period of the pilot frequency point or suspending the measurement of the pilot frequency point according to the signal measurement result of the pilot frequency point.
According to the scheme, invalid measurement can be effectively reduced, and the power consumption of the UE is further reduced. Specifically, for each pilot frequency point to be measured, the measurement period of the pilot frequency point is flexibly adjusted according to the actual signal quality of the pilot frequency point, and even the measurement of the pilot frequency point is stopped within a certain time, so that the invalid measurement is effectively reduced or even avoided, and the reduction of the power consumption of the UE becomes possible.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Fig. 1 is a flowchart of a pilot frequency measurement relaxing method according to an embodiment of the present invention. The scheme of this embodiment may be executed by the user equipment side, for example, by the UE in the RRC idle state or the inactive state on the user equipment side.
Specifically, referring to fig. 1, the inter-frequency measurement relaxing method according to this embodiment may include the following steps:
step S101, obtaining a signal measurement result of at least one pilot frequency point;
step S102, aiming at each pilot frequency point, adjusting the measurement period of the pilot frequency point or suspending the measurement of the pilot frequency point according to the signal measurement result of the pilot frequency point.
In one implementation, the pilot frequency points may include high priority frequency points, same priority frequency points, and low priority frequency points. Specifically, the UE may determine which type of pilot frequency point the measurement operation is performed for according to the signal quality of the serving cell.
For example, the step S101 may include the steps of: and when the signal quality of the serving cell is higher than a preset pilot frequency starting measurement threshold, measuring the high-priority frequency point to obtain a signal measurement result of the high-priority frequency point. For ease of presentation, this scenario will be referred to as scenario one, i.e., a scenario in which measurements are made only for high priority frequency bins.
The quality of the signal of the serving cell is higher than the preset pilot frequency threshold may be: the downlink received signal amplitude (Srxlev) of the serving Cell for Cell selection and judgment is higher than a preset pilot frequency starting measurement amplitude threshold SnonIntraSearchPAnd, the downlink received signal quality (Cell selection quality value, abbreviated as square) for Cell selection judgment of the serving Cell is higher than a preset pilot frequency starting quality measurement threshold SnonIntraSearchQ。
The preset pilot frequency starting amplitude measurement threshold SnonIntraSearchPAnd a preset pilot frequency start quality threshold SnonIntraSearchQAre both network configured parameters related to measurements and cell reselection.
For another example, the step S101 may include the steps of: and when the signal quality of the serving cell is lower than the preset pilot frequency start measurement threshold, measuring the high-priority frequency point, the same-priority frequency point and the low-priority frequency point to obtain the signal measurement results of the high-priority frequency point, the same-priority frequency point and the low-priority frequency point. For convenience of description, this scenario is referred to as scenario two, that is, a scenario in which measurements are performed on a high priority frequency point, a same priority frequency point, and a low priority frequency point.
Wherein, the signal quality of the serving cell being lower than the preset pilot frequency threshold may refer to: the downlink received signal amplitude of the serving cell for cell selection judgment is lower than the preset pilot frequency starting measurement amplitude threshold, or the downlink received signal quality of the serving cell for cell selection judgment is lower than the preset pilot frequency starting measurement quality threshold. That is, Srxlev ≦ SnonIntraSearchPOr Squal ≦ SnonIntraSearchQ。
Furthermore, the number of the high priority frequency points may be one or more, the number of the frequency points with the same priority may be one or more, and the number of the frequency points with the low priority may also be one or more.
In one implementation, the step S102 may include the steps of: and when the signal measurement result of the pilot frequency point shows that the signal quality of all adjacent cells of the pilot frequency point is lower than a preset frequency point reselection threshold, prolonging the measurement period of the pilot frequency point or suspending the measurement of the pilot frequency point. Therefore, when the signal quality of a certain pilot frequency point is far lower than the reselection threshold, the measurement of the pilot frequency point can be stopped within a certain time, or the measurement period of the pilot frequency point can be prolonged.
Further, for other pilot frequency points except the pilot frequency point in at least one pilot frequency point, the previous measurement period is maintained. In other words, for all the different-frequency bins measured in step S101, the adjustment logic of the measurement period of each different-frequency bin is independent of other different-frequency bins. Therefore, the measurement period of the pilot frequency point with poor signal quality can be independently adjusted aiming at the pilot frequency point, and even the measurement operation of the pilot frequency point is suspended.
For example, the measurement period after at least one pilot frequency point in the plurality of pilot frequency points is adjusted may be different from the measurement periods after other pilot frequency points are adjusted.
For another example, only part of the measurements of the pilot frequency points in the plurality of pilot frequency points may be suspended.
In a specific implementation, that the signal quality of all neighboring cells of the pilot frequency point is lower than a preset frequency point reselection threshold may be: when a broadcast service cell reselection quality threshold (threshServingLowQ) in a System Information Block (SIB for short), the downlink received signal quality for cell selection judgment of all adjacent cells of the pilot frequency point is lower than the preset frequency point reselection quality threshold of the pilot frequency point minus a first preset offset 1; when the serving cell reselection quality threshold is not broadcast in the SIB, the downlink received signal amplitudes used for cell selection judgment of all neighboring cells of the pilot frequency point are all lower than the preset frequency point reselection amplitude threshold minus the first preset offset1 of the pilot frequency point.
Specifically, the preset frequency point reselection amplitude threshold may be associated with the frequency point type of the pilot frequency point.
For example, the high priority frequency point may correspond to a preset high priority frequency point reselection amplitude threshold ThreshX,HighPThe low priority frequency point may correspond to a preset low priority frequency point reselection amplitude threshold ThreshX,LowP。
Similarly, the preset frequency point reselection quality threshold may also be associated with the frequency point type of the pilot frequency point.
For example, the high priority frequency point may correspond to a preset high priority frequency point reselection quality threshold ThreshX,HighQThe low priority frequency point may correspond to a preset low priority frequency point reselection quality threshold ThreshX,LowQ。
The preset high-priority frequency point reselection quality threshold ThreshX,HighQThe reselection quality threshold Thresh of the preset low-priority frequency pointX,LowQPresetting a reselection amplitude threshold Thresh of high priority frequency pointX,HighPAnd presetting a low priority frequency point reselection amplitude threshold ThreshX,LowPBoth parameters relating to measurements and cell reselection may be configured for the network.
Correspondingly, in step S102, for a high-priority frequency point, when it is found through measurement that the signal quality of all neighboring cells of a certain high-priority frequency point satisfies Squal<(ThreshX,HighQOffset1), the UE may extend the measurement period of the high priority inter-frequency bin or suspend the measurement of the high priority frequency bin. At this time, the serving cell reselection quality threshold is broadcasted in the SIB.
Or when the signal quality of all the adjacent regions of a certain high-priority frequency point is found to meet the Srxlev by measurement<(ThreshX,HighPOffset1), the UE may extend the measurement period of the high priority inter-frequency bin or suspend the measurement of the high priority frequency bin. At this point, there is no serving cell reselection quality threshold in the SIB.
Correspondingly, in the step S102, for the low priority frequency point, when measuringFinding that the signal quality of all the adjacent cells of a certain low-priority frequency point meets the Square<(ThreshX,LowQOffset1), the UE may extend the measurement period of the high priority inter-frequency bin or suspend the measurement of the high priority frequency bin. At this time, the serving cell reselection quality threshold is broadcasted in the SIB.
Or when the signal quality of all the adjacent regions of a certain low-priority frequency point is found to meet the Srxlev by measurement<(ThreshX,LowPOffset1), the UE may extend the measurement period of the low priority inter-frequency bin or suspend the measurement of the high priority frequency bin. At this point, there is no serving cell reselection quality threshold in the SIB.
In a specific implementation, when the pilot frequency point is a frequency point with the same priority, the fact that the signal quality of all neighboring cells of the pilot frequency point is lower than a preset frequency point reselection threshold may refer to: downlink received signal quality Squal for cell selection decision for a serving cellServing cellAnd the downlink received signal quality Squal used for cell selection judgment of all the adjacent cells of the pilot frequency pointNeighborhood zoneThe differences are all greater than a first predetermined offset1, SqualServing cell－SqualNeighborhood zone>offset 1. And, downlink received signal amplitude Srxlev for cell selection judgment of the serving cellServing cellAnd the downlink received signal amplitude Srxlev used for cell selection judgment of all adjacent cells of the pilot frequency pointNeighborhood zoneThe difference is greater than the first preset offset1, i.e. SrxlevServing cell－SrxlevNeighborhood zone>offset1。
In a specific implementation, the extending the measurement period of the pilot frequency point in step S102 may include: and prolonging the preset length on the basis of the current measurement period of the pilot frequency point.
In one non-limiting embodiment, the preset length may be extended based on a standard measurement period of the pilot frequency point, where the standard measurement period is determined by a protocol.
The standard measurement period may be associated with a frequency bin type of the pilot frequency bin. Further, the standard measurement period may also be associated with the scenario in which inter-frequency measurement is triggered.
For example, a high priority frequency bin may correspond to a standard measurement period T of the high priority frequency binhigher_priority_searchAnd Tmeasure,NR_Inter. Wherein, Thigher_priority_searchFor the existing protocol to meet the measurement period requirement of high priority frequency point in the scene, Tmeasure,NR_InterThe method meets the requirement of the existing protocol on the measurement period of the high-priority frequency point in the second scene.
Correspondingly, the step of extending the preset length on the basis of the current measurement period of the pilot frequency point may be as follows: in scenario one, at least every M Thigher_priority_searchPeriodically searching the high priority frequency point once, or at least every M T when searching the high priority frequency point in the scene twomeasure,NR_InterAnd periodically measuring the high-priority frequency point once. Wherein M is the preset length. M may be greater than 1.
Also for example, a low priority bin may correspond to a standard measurement period K of the low priority bincarrier*Tmeasure,NR_InterWherein, K iscarrier*Tmeasure,NR_InterFor the measurement period requirement of the existing protocol on the low-priority frequency point in the second scene, KcarrierAnd the number of pilot frequency points to be measured in an idle state or an inactive state for the UE broadcasted by the serving cell.
Correspondingly, the step of extending the preset length on the basis of the current measurement period of the pilot frequency point may be as follows: when searching for low priority frequency points in scene two, the UE may search for low priority frequency points at least every M Kcarrier*Tmeasure,NR_InterAnd periodically measuring the low-priority frequency point once. Wherein M is the preset length. M may be greater than 1.
For another example, the frequency points with the same priority may correspond to the standard measurement period K of the frequency points with the same prioritycarrier*Tmeasure,NR_Inter. Correspondingly, the step of extending the preset length on the basis of the current measurement period of the pilot frequency point may be as follows: when searching the frequency points with the same priority in the second scene, the UE can search at least every M x Kcarrier*Tmeasure,NR_InterAnd periodically measuring the frequency points with the same priority. Wherein M is as defined aboveThe length is preset. M may be greater than 1.
In one embodiment, the pilot frequency points of different frequency point types may correspond to different preset lengths.
For example, the higher the priority, the smaller the preset length corresponding to the inter-frequency point. That is, M of a high priority bin may be less than or equal to M of a low priority bin.
In another non-limiting embodiment, the preset length may be extended based on the current measurement period of the pilot frequency point. For example, the measurement period of the pilot frequency point has been extended, and if the signal quality of the pilot frequency point is still poor in the subsequent measurement process, the measurement period of the pilot frequency point can be further extended.
In a specific implementation, the suspending the measurement of the pilot frequency point in step S102 may include: and starting a timer, and stopping measuring the pilot frequency point before the timer expires.
Specifically, stopping the measurement of the pilot frequency point before the timer expires may include: and during the running period of the timer, the UE does not search the pilot frequency point.
At this time, the pilot frequency point may be a high priority frequency point in the first scene, may also be a high priority frequency point in the second scene, and may also be a same priority frequency point or a low priority frequency point in the second scene.
In one implementation, the pilot frequency points of different frequency point types may correspond to timers of different durations.
For example, the higher the priority, the smaller the duration of the timer corresponding to the inter-frequency point. That is, the duration of the timer of the high priority frequency point may be less than or equal to the duration of the timer of the low priority frequency point.
In a variation, after the number of times of extension of the measurement period of the pilot frequency point reaches a preset number of times, the measurement of the pilot frequency point may be suspended.
In one implementation, the step S102 may include: and when the signal measurement result of the pilot frequency point shows that the signal quality of any adjacent cell of the pilot frequency point is higher than a preset frequency point reselection threshold, shortening the measurement period of the pilot frequency point. Therefore, when the signal quality of the pilot frequency point of which the measurement period is prolonged to a better degree due to poor signal quality in the early stage is recovered, the measurement period of the pilot frequency point can be properly shortened, so that the signal change condition of the pilot frequency point can be acquired more accurately and timely.
Further, for all the pilot frequency points measured in step S101, the pilot frequency points other than the pilot frequency point may maintain the previous measurement period.
In a specific implementation, the fact that the signal quality of any neighboring cell of the pilot frequency point is higher than a preset frequency point reselection threshold may refer to: when a broadcast service cell reselection quality threshold (threshServingLowQ) in the SIB is detected, the downlink received signal quality for cell selection judgment of any adjacent cell of the pilot frequency point is higher than that obtained by subtracting a second preset offset2 from the reselection quality threshold of the pilot frequency point; when the serving cell reselection quality threshold is not broadcast in the SIB, the downlink received signal amplitude used for cell selection judgment in any neighboring cell of the pilot frequency point is higher than the preset frequency point reselection amplitude threshold minus a second preset offset2 of the pilot frequency point.
For example, for a high priority frequency point, when the signal quality of any neighbor cell of a certain high priority frequency point is found to satisfy Squal through measurement>(ThreshX,HighQOffset2), the UE can shorten the measurement period of the high priority inter-frequency bin. At this time, the serving cell reselection quality threshold is broadcasted in the SIB.
Or when the signal quality of any adjacent region of a certain high-priority frequency point is found to meet the Srxlev requirement through measurement>(ThreshX,HighPOffset2), the UE can shorten the measurement period of the high priority inter-frequency bin. At this point, there is no serving cell reselection quality threshold in the SIB.
Correspondingly, in step S102, for a low-priority frequency point, when it is found through measurement that the signal quality of any neighbor cell of a certain low-priority frequency point satisfies Squal>(ThreshX,LowQOffset2), the UE can shorten the measurement period of the high priority inter-frequency bin. At this timeThe broadcast serving cell reselection quality threshold in the SIB.
Or when the signal quality of any adjacent region of a certain high-priority frequency point is found to meet the Srxlev requirement through measurement>(ThreshX,LowPOffset2), the UE can shorten the measurement period of the high priority inter-frequency bin. At this point, there is no serving cell reselection quality threshold in the SIB.
In a specific implementation, when the pilot frequency point is a frequency point with the same priority, the quality of the signal in any neighboring cell of the pilot frequency point being higher than the preset frequency point reselection threshold may be: downlink received signal quality Squal for cell selection decision for a serving cellServing cellAnd the downlink received signal quality Squal used for cell selection judgment of any adjacent cell of the pilot frequency pointNeighborhood zoneThe difference is less than a second predetermined offset2, SqualServing cell－SqualNeighborhood zone<offset 2. Or the downlink received signal amplitude Srxlev of the serving cell for cell selection judgmentServing cellAnd the downlink received signal amplitude Srxlev used for cell selection judgment of any adjacent cell of the pilot frequency pointNeighborhood zoneThe difference is smaller than the second preset offset2, SrxlevServing cell－SrxlevNeighborhood zone<offset2。
In a specific implementation, the shortening the measurement period of the pilot frequency point in step S102 may include: and restoring the measurement period of the pilot frequency point to a standard measurement period, wherein the standard measurement period is determined by a protocol.
For example, in scenario one, the UE reverts to at least every Thigher_priority_searchThe high priority frequency point is periodically searched once.
Also for example, when searching for high priority frequency points in scene two, the UE reverts to at least every Tmeasure,NR_InterThe high priority frequency point is periodically searched once.
For another example, when scene two searches for low priority bins, the UE reverts to at least every Kcarrier*Tmeasure,NR_InterThe low priority frequency point is periodically searched once.
As another example, at scene two searchWhen the frequency points with the same priority are in the same priority, the UE is recovered to be at least every Kcarrier*Tmeasure,NR_InterAnd periodically searching the frequency points with the same priority once.
In a variation, the measurement period of the pilot frequency point may be restored to the measurement period before adjustment. For example, in the case that the pilot frequency point is extended by the measurement period for multiple times, the measurement period of the pilot frequency point may be restored to the measurement period before the last adjustment.
Further, if the signal quality of the pilot frequency point is gradually improved in the next measurement, the measurement period of the pilot frequency point is gradually recovered to the standard measurement period.
In this embodiment, the durations of the first preset Offset1, the second preset Offset2 and the timer may be network configuration or default values.
Therefore, by adopting the scheme of the embodiment, invalid measurement can be effectively reduced, and the power consumption of the UE is further reduced. Specifically, for each pilot frequency point to be measured, the measurement period of the pilot frequency point is flexibly adjusted according to the actual signal quality of the pilot frequency point, and even the measurement of the pilot frequency point is stopped within a certain time, so that the invalid measurement is effectively reduced or even avoided, and the reduction of the power consumption of the UE becomes possible.
