Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for triggering a measurement report, and a user equipment.
Background
In a mobile communication system, a connected User Equipment (UE) needs to measure a serving cell and an adjacent cell, and report a measurement report to a serving base station when a reporting condition is satisfied, and the serving base station determines whether to switch cells according to the measurement report (or according to other factors, such as cell load). In a Long Term Evolution (LTE) system, measurement events are all measured by a cell, for example, measurement event A3 indicates that a signal of a neighboring cell is higher than a signal of a main cell by a set offset, measurement event a4 indicates that the signal of the neighboring cell is higher than a set threshold, where the signal is the signal quality or signal strength of the neighboring cell or the main cell measured by the UE.
In a fifth Generation mobile communication technology (5-Generation,5G) system, 5G is deployed at high frequency, wireless signals exhibit characteristics of good directivity and large path loss at high frequency, a cell with a large coverage area needs a plurality of beams (Beam) to realize complete coverage, and a single Beam can only cover a limited area. A cell with a small coverage area may contain only one beam. For a cell formed by multiple beams, due to the limitation of hardware, not all beams can be transmitted at the same time, and time-sharing transmission is required, which is called Beam Sweeping (Beam Sweeping).
When the user equipment in a connected state moves in the 5G system, beams of a serving cell and neighboring cells need to be measured. In the prior art, when measuring a neighboring cell having multiple beams, a UE generates a cell-level measurement value (which may be referred To as a cell measurement value) according To one or more beams of a signal of the neighboring cell, and determines whether a reporting condition is met according To the cell-level measurement value, for example, when the measurement value exceeds a threshold, a timer (Time To Trigger, TTT) is started (a set Time may be 40ms, 60ms, or 80ms, and the like), and if the measurement value continuously exceeds the threshold within the TTT, the UE needs To Trigger reporting of a measurement report, where the measurement report includes the measurement value of the neighboring cell at this Time.
However, when measuring a neighboring cell having multiple beams, the best multiple beams of the same neighboring cell may change, and especially the movement of the UE causes the best beam of a signal measured by the UE when measuring the neighboring cell to change frequently, but if a cell measurement value formed by the multiple beams having the best signal does not change, according to the prior art, because the measurement value of the cell does not change, the UE does not report a measurement report at this time, so that the base station cannot timely know information of the best beam of the neighboring cell measured by the UE, and cannot know the change of a channel where the UE is located, which affects cell handover to the UE, and further affects data transmission between the UE and the base station.

Compared with the prior art that the triggering measurement report condition is judged according to the cell-level measurement value, the technical scheme of the invention compares the beam information of the optimal beam or the cell measurement value with the beam information of the service beam of the service cell, so that the base station can further obtain the beam information of the optimal beam of the adjacent cell in time, and therefore when cell switching is determined, the beam of the cell with better signal is switched to, and the efficiency of data transmission between the base station and the user equipment is improved.

Detailed Description
As described in the background art, when a user equipment in the prior art performs measurement on a neighboring cell having multiple beams, the best multiple beams of the same neighboring cell may change, and especially, the beam with the best measured signal when the UE measures the neighboring cell may change frequently due to the movement of the UE. However, if the cell measurement value formed by the multiple beams with the best signal does not change, according to the prior art, because the cell measurement value does not change, the UE does not report the measurement report at this time, so that the base station cannot timely know the information of the best beam of the neighboring cell measured by the UE, and the base station cannot know the change of the channel where the UE is located, thereby affecting the cell handover of the UE and further affecting the data transmission between the UE and the base station.
Therefore, in the prior art, the trigger condition of the measurement report or the reported content is not reasonable, the base station cannot timely acquire the information of the optimal beam of the neighboring cell measured by the UE, and the base station needs to configure the handover parameter according to the optimal beam measured by the UE during handover, so that the configuration of the handover parameter of the UE is not proper, and the execution of the handover is affected.
The embodiment of the invention firstly determines the beam information of the beam set of the adjacent cell which meets the reporting condition, and triggers the reporting of the measurement report again when the marks of the optimal M beams of one adjacent cell are changed, thereby being beneficial to the base station to obtain the beam information of the optimal beam of the adjacent cell in time, switching to the beam of the cell with better signal when deciding the cell switching, and further improving the efficiency of data transmission between the base station and the user equipment.
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 measurement report triggering method according to an embodiment of the present invention.
The measurement report triggering method shown in fig. 1 may include the steps of:
step S101: determining beam information of a beam set, wherein the beam information of the beam set comprises beam information of adjacent cells meeting reporting conditions, the beam information comprises identifiers and/or signal information of beams, and the beam set comprises optimal N beams of each adjacent cell obtained through measurement;
step S102: and at least changing the identifiers of the optimal M wave beams of one adjacent cell, and triggering the report of the measurement report again when the changed adjacent cell meets the report condition, wherein N is a positive integer larger than or equal to 1, and M is a positive integer smaller than or equal to N.
The measurement report triggering method of the present embodiment may be performed at the user equipment side.
In a specific implementation, in step S101, beam information of a beam set may be determined, where the beam information of the beam set includes beam information of a neighboring cell that meets a reporting condition. That is, if the ue meets the reporting condition in the neighboring cell, the ue may store or maintain the beam information of the neighboring cell when reporting the measurement report. The beam information includes the identifier and/or signal information of the beam, and the beam set includes the measured optimal N beams of each neighboring cell that satisfy the reporting condition. It is understood that the values of N and M may be previously configured by the base station for the user equipment, for example, N is 5, M is 3, and so on. N and M may also be protocol preset.
In a specific implementation, in step S101, when determining the beam information, the user equipment may respectively determine the beam information of the neighboring cell that satisfies the reporting condition on each frequency according to the frequency, and then when "the identifier of the optimal M beams of the neighboring cell is determined to be changed", the determination may also be performed in units of frequency. In this case, the measurement report can only contain neighbor information on one frequency.
Or, the user equipment may determine, according to the multiple frequencies, the beam information of the neighboring cells that satisfy the reporting condition on the multiple frequencies, and then determine whether the identifiers of the optimal M beams of the neighboring cells on the multiple frequencies are changed, where the measurement report may include the neighboring cell information on the multiple frequencies.
Preferably, the signal information comprises signal strength and/or signal quality. Wherein the signal strength may represent the received power of the signal and the signal quality may represent the degree of interference, e.g. the signal-to-noise ratio, of the signal. The UE may identify and measure the signal strength and signal quality of different beams of different neighbors.
It should be understood by those skilled in the art that the neighbor cell meeting the reporting condition in this embodiment may be consistent with the neighbor cell meeting the reporting condition in the prior art, for example, the cell measurement value of the neighbor cell exceeds a threshold, or the cell measurement value of the neighbor cell is higher than the cell measurement value of the serving cell by a set value; or may be a newly added measurement event.
Specifically, after triggering the report of the measurement report, the UE may store the beam information of the beam set, so as to be convenient for the subsequent steps to invoke for use. For example, the UE may store and maintain a list to record the beam identifiers, beam signal strengths, and the like of the optimal N beams of each neighboring cell that satisfy the reporting condition.
In specific implementation, in step S102, the reporting of the measurement report is triggered again at least according to that the identifier of the optimal M beams of at least one neighboring cell changes, and the changed neighboring cell meets the reporting condition. In other words, if the UE detects that the identities of the optimal M beams of a certain neighboring cell change, the UE needs to trigger the reporting of the measurement report again.
Specifically, the change of the identifiers of the optimal M beams may be a change of the order of the identifiers of the optimal M beams in the neighboring cell. For example, the identifiers of the currently optimal 3 beams in the neighboring cell are beam 1, beam 2, and beam 3 in the order from strong to weak in signal strength, and then the identifiers of the optimal 3 beams are changed into beam 2, beam 3, and beam 1 in the order from strong to weak in signal strength, so that the UE may trigger the reporting of the measurement report again.
The identifier of the optimal M beams may be changed, or another beam may replace at least one of the current optimal M beams. For example, if the currently optimal 3 beam identities are beam 1, beam 2, and beam 3, and then the optimal 3 beam identities are changed to beam 1, beam 2, and beam 4, the UE may trigger reporting of the measurement report again.
Alternatively, the identifier of the optimal M beams may be changed, that is, the number of the current optimal M beams is reduced. For example, if the currently optimal 3 beam identities are beam 1, beam 2, and beam 3, and then the optimal 3 beam identities are changed to beam 1 and beam 2, the UE may trigger reporting of the measurement report again.
It should be noted that, when the signal information of the optimal M beams changes, for example, the signal strength becomes stronger or weaker, the ue may determine whether to trigger reporting of the measurement report again according to the actual situation or in combination with other determination conditions.
It can be understood that, when the reporting condition is satisfied for the first time in the same neighboring cell to trigger a measurement report, there is no need to consider the situation that the beams in the beam set change, because there is no reference for comparison. When a neighboring cell meets a reporting condition for the first time, the reporting condition is usually required to be met for a certain time; and after the signal information of the optimal M wave beams of the adjacent cell is changed, if the adjacent cell meets the reporting condition and does not need to meet the reporting condition for a certain time, the reporting of the measurement report can be triggered.
The embodiment of the invention firstly determines the reported wave beam information of the wave beam set, and triggers the report of the measurement report again when the marks of the optimal M wave beams of one adjacent cell are changed, thereby being beneficial to the base station to obtain the wave beam information of the optimal wave beams of the adjacent cell in time, switching to the wave beam of the cell with better signal when deciding the cell switching, and further improving the efficiency of data transmission between the base station and the user equipment. Further, when the user equipment is in a measurement neighborhood, the report of the measurement report can be triggered when the optimal beam changes, so that the target base station can timely acquire the change of the optimal beam signal, and the wireless parameters corresponding to the optimal beam can be configured for the user equipment during switching.
Preferably, the measurement report includes a cell identifier of the neighboring cell and beam identifiers of the M changed beams. That is, when the ue reports the measurement report, the ue may carry the changed beam identifiers of the M beams in the measurement report; the beam information of the beam which is not changed does not need to be carried in the measurement report, so as to avoid resource waste between the user equipment and the base station. It can be understood that the reported measurement report carries the cell identifier corresponding to the neighboring cell, regardless of the changed beam identifiers of the M beams or the beam information of the beam that has not been changed.
Preferably, since the measurement value of the beam information in the actual network has jitter, the duration may be increased as a re-triggering condition of the measurement report, so as to avoid an increase in the measurement report caused by the jitter of the neighbor cell signal.
Preferably, step S102 may include the steps of: and if the identifiers of the optimal M wave beams are changed, the changed neighbor cell meets the reporting condition, and the duration time for which the identifiers of the M wave beams are not changed after the change reaches a first set time, triggering the reporting of the measurement report again. In other words, on the premise that the neighboring cell still satisfies the reporting condition, if the identifiers of the optimal M beams are changed and the duration of the changed identifiers of the M beams reaches the first set time, the reporting of the measurement report is triggered again, so that the situation that the measurement report is frequently reported due to frequent change of beam information is avoided, the increase of the measurement report caused by the jitter of the neighboring cell signal is avoided, and the resource waste of the user equipment and the base station is reduced.
For example, currently, the optimal 3 beam identifiers are beam 1, beam 2, and beam 3, then the optimal 3 beam identifiers are changed into beam 1 and beam 2, and at this time, the identifiers of the 3 beams are changed, that is, the condition of "the optimal 3 beam identifiers are changed" is satisfied, but since the number of the changed beams is reduced to 2, as long as the duration of the beam 1 and the beam 2 as the optimal beam reaches the first set time, the UE may trigger the reporting of the measurement report again.
Preferably, step S102 may include the steps of: if the optimal M wave beams have changed, the changed signal information of the M wave beams all reach a set threshold, meanwhile, the duration time of the set threshold exceeds a second set time (the time length can be 0 or more than 0), and the adjacent cell meets the reporting condition, the reporting of the measurement report is triggered again. In the embodiment of the invention, the optimal M wave beam identifiers are changed, the changed signal information (such as signal strength or signal quality) of at most M wave beams reaches the set threshold, and the re-reporting of the measurement report is triggered when the duration time reaches the second set time, so that the situation that the measurement report is frequently reported due to frequent change of the wave beam information is avoided, the measurement report is prevented from being increased due to adjacent cell signal jitter, and the expenses of user equipment and a base station are reduced.
It is understood that the time lengths of the first set time and the second set time may be the same as or different from the set time length of the timer (TTT) in the related art, for example, the time lengths of the first set time and the second set time may be lower than the set time length.
Preferably, step S102 may include the steps of: and if the identification of the optimal M wave beams is changed, the changed adjacent cell is one of the cells with the set number of optimal signals on the frequency of the changed adjacent cell, and the changed adjacent cell meets the reporting condition, triggering the reporting of the measurement report again. That is to say, the UE only reports the measurement report of the neighboring cells with the optimal signal and the set number, and if the beam of the neighboring cells with the non-optimal set number changes, the UE triggers reporting of the measurement report is not significant for the base station to switch the cell. The embodiment of the invention triggers the report of the measurement report when the marks of the optimal M wave beams are changed and the signal of the adjacent cell is better, thereby avoiding the report of the measurement report caused by the wave beam change of the adjacent cell with weaker signal, realizing the optimization of the trigger mechanism of the measurement report, being beneficial to the cell switching of the base station and reducing the expense of the base station. It is understood that the set number may be configured in advance by the base station, and the set number may be 1 or a value greater than 1.
Fig. 2 is a schematic diagram of an application scenario in which the measurement report triggering method according to the embodiment of the present invention is adopted.
As shown in fig. 2, the horizontal axis represents time, and the vertical axis represents measurement values. Curve 2 is the measured value of beam X over time, curve 3 represents the measured value of beam Y over time, and curve 1 represents the measured values of the cells of the neighbourhood where beam X and beam Y are located over time. It will be appreciated that the measurements of beam X and beam Y may be their signal strengths or signal qualities.
Continuing with fig. 2, at time t1, when the cell measurement value reaches the cell measurement value measurement report threshold, as shown in point a in the figure, the UE may trigger reporting of the first measurement report at time t1, or may trigger reporting of the first measurement report at time t1+ TTT after the duration exceeds the set time period TTT, so as to avoid increase of measurement reports caused by signal jitter. When the report of the measurement report is triggered for the first time, the optimal wave beam of the neighboring cell is the wave beam X. At time t2, the cell measurement value of the neighboring cell is still greater than the cell measurement value measurement report threshold, but the optimal beam of the neighboring cell changes from beam X to beam Y, as shown by point B in the figure, the UE may trigger the reporting of the measurement report again at time t2 to bring the optimal beam information to the network; after the duration exceeds the set time period TTT, the reporting of the measurement report may be triggered at time t2+ TTT, so as to avoid the increase of the measurement report caused by signal jitter.
Preferably, when the ue triggers to report the measurement report twice for the same neighboring cell, and a difference between two consecutive times of measurement reports for the same cell is smaller than a set time threshold, the ue carries the beam information of the at least one beam when the measurement report is to be triggered for the second time when the measurement report is triggered for the first time in the two times of measurement reports, and cancels the reporting of the measurement report triggered for the second time. The user equipment of the embodiment of the invention determines to cancel the reporting operation of the second triggering measurement report when judging that the difference value of the time for triggering and reporting the measurement report twice is smaller than the set time threshold, and carries the changed beam identifiers of the M beams for triggering the measurement report twice when the measurement report is triggered for the first time in the measurement reports twice, thereby avoiding the situation that the measurement report is frequently reported due to frequent change of beam information, avoiding the increase of the measurement report caused by adjacent cell signal jitter, and reducing the expenses of the user equipment and the base station.
It should be noted that, the "reporting measurement report triggered twice" referred to in this embodiment may be triggered by determining that two measurement reports continuously occur for the same neighboring UE. Since the UE maintains the measurement values of the optimal M beams of the neighboring cell, this determination can be made in combination with the measurement sampling requirement of the UE for the neighboring cell. And the time between two times of triggering and reporting the measurement report does not exist for triggering and reporting the measurement report aiming at the neighboring cell.
Fig. 3 is a schematic diagram of another application scenario in which the measurement report triggering method according to the embodiment of the present invention is adopted.
Referring to fig. 3, for the same neighbor cell, the beam set includes beam 1, beam 2, and beam 3. The signal strength of the beams of the beam set other than beams 1, 2, 3 is assumed to be unchanged. At time T3, the UE measures that the optimal beam is changed to beam 1, and if the state of the optimal beam being beam 1 remains unchanged (i.e. the signal information of beam 1 may change but continues to be the optimal beam) within a first set time after time T3, the UE needs to report a measurement report at time T3+ T1. Meanwhile, the UE also measures that the optimal beam is changed to beam 2 at time T4, and if the state that the optimal beam is beam 2 is maintained within the first set time after time T4, the UE also needs to report a measurement report at time T4+ T1. Because the time difference value delta T1 between the time T3 and the time T4 is smaller than the set time threshold value delta T, in order to avoid frequent sending of the measurement report, the UE can report the measurement report only at the time T3+ T1, and does not report the measurement report any more at the time T4+ T1; meanwhile, the measurement report reported at the time T3+ T1 carries the signal strength after the beam 1 and the beam 2 are changed.
Meanwhile, the UE also measures that the optimal beam is changed to beam 3 at time T5, and if the state that the optimal beam is beam 3 remains unchanged within the first set time after time T5, the UE also needs to report a measurement report at time T5+ T1. Since the time difference Δ T2 between time T5 and time T4 is greater than the set time threshold Δ T, the UE may report a measurement report at T5+ T1.
It can be understood that, for the scenario shown in fig. 3, the second set time may also be used in practical applications, and the embodiment of the present invention is not limited thereto.
In the prior art, that the neighboring cell satisfies the reporting condition means that the cell measurement value of the neighboring cell reaches the threshold corresponding to the reporting condition. In this embodiment, it is considered that the report of the measurement report may also be triggered when the identifier of the optimal M beams changes, and the neighbor cell satisfies the report condition may not only be limited that the cell measurement value of the neighbor cell reaches the cell measurement value measurement report threshold, but also may perform the determination on the beam level.
Preferably, the serving cell may comprise a plurality of beams, but typically only a single serving beam is present; in other words, the UE usually has only one beam in the serving cell to provide service for the UE, i.e. the serving beam is the beam with the best serving cell signal to serve the UE, so as to achieve better spectrum efficiency. Then, the neighbor cell satisfying the reporting condition at least includes one or more of the following measurement events:
the signal information of the optimal wave beam of the adjacent area reaches a set threshold;
the signal information of the optimal beam is higher than the signal information of the service beam of the service cell by a set offset;
the signal information of the optimal beam reaches a first threshold, and the signal information of the service beam is lower than a second threshold;
and the comprehensive measurement value of the plurality of optimal beams in the adjacent region is higher than the signal information of the service beam by a set offset.
Specifically, when determining whether the neighboring cell satisfies the reporting condition, the UE may determine according to the beam information of the optimal beam. When the signal information of the optimal beam reaches a set threshold, or the signal information of the optimal beam is higher than the signal information of the serving beam by a set offset, the UE may trigger reporting of a measurement report. That is, when the optimal beam signal of the neighboring cell is better, the report of the measurement report can be triggered. Or, when the signal information of the optimal beam reaches the first threshold and the signal information of the serving beam is lower than the second threshold, the UE may trigger reporting of a measurement report. That is, when the optimal beam signal of the neighboring cell is better and the serving beam signal of the serving cell is worse, the report of the measurement report may be triggered. Meanwhile, the measured value of the cell can be compared with the signal information of the service beam, and when the measured value of the cell is higher than the signal information of the service beam by a set offset, the report of the measurement report is triggered.
It should be understood by those skilled in the art that, in practical applications, when the UE reports the measurement report, the measurement event may be a time when the measurement event satisfies the measurement event, or a time when a first set time or a second set time after the measurement event satisfies the measurement event is measured (that is, the measurement event continuously satisfies the first set time or the second set time), and this is not limited in this embodiment of the present invention.
The above embodiments are specifically described below with reference to specific application scenarios.
Continuing with fig. 3, assume that the signal strengths of beams 1, 2, and 3 increase in sequence, becoming the optimal beams in sequence. At time T3, the UE detects that the signal strength of the beam 1 satisfies the reporting condition, that is, the signal strength of the optimal beam exceeds the set threshold (or exceeds the signal information of the serving beam by the set offset), and then after the signal strength of the beam 1 lasts for the first set time T1, it needs to trigger reporting of the measurement report. Meanwhile, at time t4, the UE also finds that beam 2 (beam 1 has higher signal strength than beam 1) satisfies the reporting condition. Because the time difference Δ T1 between the occasions when the beam 1 and the beam 2 trigger the reporting of the measurement report is smaller than the set time threshold Δ T, that is, the time difference Δ T1 between the time T3 and the time T4 is smaller than the set time threshold Δ T, when the beam 1 triggers the reporting of the measurement report, the UE simultaneously carries the beam information of the beam 2, and the beam 2 is prevented from triggering the reporting of the measurement report again.
Alternatively, the UE may wait for the reporting time T4+ T1 corresponding to the beam 2 to time out before reporting the measurement report corresponding to the beam 2.
At time t5, the UE also finds that beam 3 (the signal strength of beam 3 is higher than that of beam 3) satisfies the reporting condition, and since the reporting times of the measurement reports of beam 3 and beam 1 are greatly different, the UE does not carry the beam information of beam 3 when beam 1 satisfies the reporting condition. And the UE triggers the reporting of the measurement report again at the moment when the beam 3 becomes the optimal beam.
Fig. 4 is a schematic structural diagram of a measurement report triggering apparatus according to an embodiment of the present invention.
The measurement report triggering apparatus 40 shown in fig. 4 may include a determination module 401 and a measurement report triggering module 402.
The determining module 401 is adapted to determine beam information of a beam set, where the beam information of the beam set includes beam information of neighboring cells that meet a reporting condition, the beam information includes identifiers and/or signal information of beams, and the beam set includes optimal N beams of each neighboring cell obtained through measurement;
the measurement report triggering module 402 is adapted to trigger reporting of the measurement report again when at least the identifiers of the optimal M beams are changed and the neighboring cell meets the reporting condition.
The measurement report triggering device 40 of the present embodiment may be executed on the user equipment side.
In a specific implementation, the beam information of the beam set includes beam information of a neighboring cell that satisfies a reporting condition. That is, if the ue meets the reporting condition, the ue may store or maintain the beam information of the neighboring cell when reporting the measurement report. The beam information includes the identifier and/or signal information of the beam, and the beam set includes the measured optimal N beams of each neighboring cell that satisfy the reporting condition. It is understood that the values of N and M may be previously configured by the base station for the user equipment, for example, N is 5, M is 3, and so on. N and M may also be protocol preset.
In a specific implementation, when the determining module 401 determines the beam information, the user equipment may respectively determine the beam information of the neighboring cell that meets the reporting condition on each frequency according to the frequency, and then when "the identifier of the optimal M beams of the neighboring cell is determined to be changed", the determination may also be performed in units of frequency. In this case, the measurement report can only contain neighbor information on one frequency.
Or, the user equipment may determine, according to the multiple frequencies, the beam information of the neighboring cells that satisfy the reporting condition on the multiple frequencies, and then determine whether the identifiers of the optimal M beams of the neighboring cells on the multiple frequencies are changed, where the measurement report may include the neighboring cell information on the multiple frequencies.
Preferably, the signal information comprises signal strength and/or signal quality. Wherein the signal strength may represent the received power of the signal and the signal quality may represent the degree of interference, e.g. the signal-to-noise ratio, of the signal. The UE may identify and measure the signal strength and signal quality of different beams of different neighbors.
It should be understood by those skilled in the art that the neighbor cell satisfying the reporting condition in this embodiment may be consistent with the neighbor cell satisfying the reporting condition in the prior art, for example, the cell measurement value of the neighbor cell exceeds a threshold, or the cell measurement value of the neighbor cell is higher than the cell measurement value of the serving cell by a set value.
Specifically, after triggering the report of the measurement report, the UE may store the beam information of the beam set in the measurement report, so as to be convenient for the subsequent steps to invoke for use. For example, the UE may store and maintain a list to record the beam identifiers, beam signal strengths, and the like of the optimal N beams of each neighboring cell that satisfy the reporting condition.
In a specific implementation, the measurement report triggering module 402 triggers reporting of the measurement report again when at least the identifiers of the optimal M beams are changed and the neighboring cell meets the reporting condition. In other words, if the beam information of the optimal beam of the neighboring cell measured by the UE changes, the UE needs to trigger the reporting of the measurement report again.
Specifically, the change of the identifiers of the optimal M beams may be a change of the order of the identifiers of the optimal M beams in the neighboring cell. For example, the identifiers of the currently optimal 3 beams in the neighboring cell are beam 1, beam 2, and beam 3 in the order from strong to weak in signal strength, and then the identifiers of the optimal 3 beams are changed into beam 2, beam 3, and beam 1 in the order from strong to weak in signal strength, so that the UE may trigger the reporting of the measurement report again.
The identifier of the optimal M beams may be changed, or another beam may replace at least one of the current optimal M beams. For example, if the currently optimal 3 beam identities are beam 1, beam 2, and beam 3, and then the optimal 3 beam identities are changed to beam 1, beam 2, and beam 4, the UE may trigger reporting of the measurement report again.
Alternatively, the identifier of the optimal M beams may be changed, that is, the number of the current optimal M beams is reduced. For example, if the currently optimal 3 beam identities are beam 1, beam 2, and beam 3, and then the optimal 3 beam identities are changed to beam 1 and beam 2, the UE may trigger reporting of the measurement report again.
It should be noted that, when the signal information of the optimal M beams changes, for example, the signal strength becomes stronger or weaker, the ue may determine whether to trigger reporting of the measurement report again according to the actual situation or in combination with other determination conditions.
It can be understood that, when the reporting condition is satisfied for the first time in the same neighboring cell to trigger a measurement report, there is no need to consider the situation that the beams in the beam set change, because there is no reference for comparison. When a neighboring cell meets a reporting condition for the first time, the reporting condition is usually required to be met for a certain time; and after the signal information of the optimal M wave beams of the adjacent cell is changed, if the adjacent cell meets the reporting condition and does not need to meet the reporting condition for a certain time, the reporting of the measurement report can be triggered.
The embodiment of the invention firstly determines the reported wave beam information of the wave beam set, and triggers the report of the measurement report again when the marks of the optimal M wave beams of one adjacent cell are changed, thereby being beneficial to the base station to obtain the wave beam information of the optimal wave beams of the adjacent cell in time, switching to the wave beam of the cell with better signal when deciding the cell switching, and further improving the efficiency of data transmission between the base station and the user equipment. Further, when the user equipment is in a measurement neighborhood, the report of the measurement report can be triggered when the optimal beam changes, so that the target base station can timely acquire the change of the optimal beam signal, and the wireless parameters corresponding to the optimal beam can be configured for the user equipment during switching.
Preferably, the measurement report may include a cell identifier of a cell in which the neighboring cell is located and beam identifiers of the changed M beams. That is, when the ue reports the measurement report, the ue may carry the changed beam identifiers of the M beams in the measurement report; the beam information of the beam which is not changed does not need to be carried in the measurement report, so as to avoid resource waste between the user equipment and the base station. It can be understood that the reported measurement report carries the cell identifier corresponding to the neighboring cell, regardless of the changed beam identifiers of the M beams or the beam information of the beam that has not been changed.
Preferably, since the measurement value of the beam information in the actual network has jitter, the duration may be increased as a re-triggering condition of the measurement report, so as to avoid an increase in the measurement report caused by the jitter of the neighbor cell signal.
Preferably, the measurement report triggering module 402 may include a first triggering unit 4021, where the first triggering unit 4021 is adapted to trigger reporting of the measurement report again when the identifiers of the optimal M beams are changed, the neighboring cell meets the reporting condition, and the duration of time during which the identifiers of at most M beams remain unchanged after the change reaches a first set time. In other words, on the premise that the neighboring cell still satisfies the reporting condition, if the identifiers of the optimal M beams are changed and the duration of the changed identifiers of the M beams reaches the first set time, the reporting of the measurement report is triggered again, so that the situation that the measurement report is frequently reported due to frequent change of beam information is avoided, the increase of the measurement report caused by the jitter of the neighboring cell signal is avoided, and the resource waste of the user equipment and the base station is reduced.
Preferably, the measurement report triggering module 402 may include a second triggering unit 4022 and a first triggering unit 4022. The second triggering unit 4022 is adapted to trigger reporting of the measurement report again when the identifier of the optimal M beams is changed, and the signal information of the M beams after the change reaches a set threshold, and simultaneously reaches a set threshold duration exceeding a second set time, and the neighboring cell meets the reporting condition. In the embodiment of the invention, the optimal M wave beam identifiers are changed, the signal information (such as signal strength or signal quality) of the changed wave beams reaches the set threshold, and the re-reporting of the measurement report is triggered when the duration time reaches the second set time, so that the situation that the measurement report is frequently reported due to frequent change of the wave beam information is avoided, the measurement report is prevented from being increased due to adjacent cell signal jitter, and the expenses of user equipment and a base station are reduced.
It is understood that the time lengths of the first set time and the second set time may be the same as or different from the set time length of the timer in the related art, for example, the time lengths of the first set time and the second set time may be lower than the set time length.
Preferably, the measurement report triggering module 402 may further include a third triggering unit 4023, where the third triggering unit 4023 is adapted to change the identifier of the optimal M beams, where the changed neighboring cell is one of the cells with the set number of optimal signals on the frequency where the changed neighboring cell is located, and when the neighboring cell meets the reporting condition, the reporting of the measurement report is triggered again. That is to say, the UE only reports the measurement report of the neighboring cells with the optimal signal and the set number, and if the beam of the beam set of the neighboring cells with the non-optimal set number changes, the UE triggers reporting of the measurement report is not significant for the base station to switch the cell. The embodiment of the invention triggers the report of the measurement report when the marks of the optimal M wave beams are changed and the signal of the adjacent cell is better, thereby avoiding the report of the measurement report caused by the wave beam change of the adjacent cell with weaker signal, realizing the optimization of the trigger mechanism of the measurement report, being beneficial to the cell switching of the base station and reducing the expense of the base station. It is understood that the set number may be configured in advance by the base station, and the set number may be 1 or a value greater than 1.
Preferably, the measurement report triggering apparatus 40 shown in fig. 4 may include a cancellation module 403, where the cancellation module 403 is adapted to, when a difference between times of triggering and reporting the measurement report for two consecutive times is smaller than a set time threshold for the same cell, carry beam information of the at least one beam when the measurement report is to be triggered for the second time when the measurement report is triggered for the first time in the two triggered measurement reports, and cancel reporting of the second triggered measurement report. The user equipment of the embodiment of the invention determines to cancel the reporting operation of the second triggering measurement report when judging that the difference value of the time for triggering and reporting the measurement report twice is smaller than the set time threshold, and carries the changed beam identifiers of the M beams for triggering the measurement report twice when the measurement report is triggered for the first time in the measurement reports twice, thereby avoiding the situation that the measurement report is frequently reported due to frequent change of beam information, avoiding the increase of the measurement report caused by adjacent cell signal jitter, and reducing the expenses of the user equipment and the base station.
