Embodiment
In background technology, mention, the metrical information of the measurement information reporting of prior art by being used for UE location is the metrical information that is used to switch, direct measured value and other relevant informations of comprising RSRP (Reference Signal Receive Power, Reference Signal Received Power) and so on.Owing to the information of the measurement information reporting that is used for the UE location is littler than the demand of the metrical information that is used to switch, be used for the measurement message that UE locatees if adopt handover measurement to report mechanism to report, there is redundancy in the metrical information that then is used to switch.In addition, adopt handover measurement mechanism to report the measurement message that is used for the UE location, can not make full use of all metrical informations that UE grasps.For example: can only utilize the average statistics amount, can not embody the situation of variance.
The embodiment of the invention provides a kind of report method of metrical information, measured value to sub-district, UE place and this adjacent cells of cells is adjudicated, obtain to measure discriminative information, and report this measurement discriminative information, the metrical information feedback mechanism is become the decision-feedback mechanism of measuring, reduce signaling consumption effectively, saved interface-free resources, can reach the purpose that the metrical information that UE is obtained fully is used for the UE location simultaneously.The embodiment of the invention is that NodeB is that example describes with the base station.
As shown in Figure 1, be the flow chart of the report method of embodiment of the invention metrical information, the embodiment of the invention is adjudicated the metrical information that UE obtains according to the location requirement of UE, reports the measurement discriminative information after the judgement, specifically may further comprise the steps:
Step S101, UE adjudicates the measured value of this sub-district and adjacent sub-district, obtains to measure discriminative information.This measurement discriminative information comprises: UE is to the rank that influences of adjacent sub-district.
UE is the measured value of this sub-district and the measured value of adjacent sub-district relatively, obtains the comparison value of the measured value of the measured value of this sub-district and adjacent sub-district.UE carries out quantization level to the comparison value that obtains then, obtains the influence rank of UE to adjacent sub-district.Method such as can take uniform quantization, non-uniform quantizing when wherein, UE carries out quantization level to the comparison value that obtains or table look-up.
For example: the uniform quantization to the RSRP measured value can be taked following mode: establishing UE reporting positioning survey thresholding is 6db, it is 0db that handover measurement reports thresholding, the quantization level number is 4, and then quantized value a is: a=(6-0)/4=1.5db, promptly every 1.5db are a quantization level.As shown in Figure 2, when in the scope of comparison value at 0～1.5db of the RSRP of this sub-district and certain adjacent sub-district measured value, UE is 3 to the rank that influences of adjacent sub-district; When the comparison value of the RSRP of this sub-district and certain adjacent sub-district during at 1.5db～3db, UE is 2 to the rank that influences of adjacent sub-district.
Because the metrical information of UE comprises RSRP, RSSI (Received Signal Strength Indication, the indication of received signal intensity), RSRQ (Reference Signal Receive Quality, Reference Signal Received Quality) etc., these metrical informations all can suppress strategy to a certain extent and exert an influence to the presence of intercell interference of NB, therefore UE also can carry out quantization level to the comparison value of the measured value of the RSSI of this sub-district and adjacent sub-district or RSRQ, obtains the rank that influences of UE to adjacent sub-district.
In addition, measure the variance that discriminative information can also comprise the measured value of this sub-district and adjacent sub-district.The variance of the measured value of this sub-district and adjacent sub-district has embodied UE and has reported the situation of interim to the variation speed of adjacent sub-district influence.At the difference of UE to the variation speed of adjacent sub-district influence, it is different that the presence of intercell interference that NB takes suppresses mechanism.For example: changing when fast, the confidence level of measuring reporting information is lower, changes when slow, and the confidence level of measuring reporting information is higher.NB can take corresponding presence of intercell interference to suppress strategy according to the confidence level size of information.
Step S102, the measurement message by being used for UE location is to NodeB reporting measurement discriminative information.NodeB can measure discriminative information according to this and take rational presence of intercell interference to suppress strategy after receiving the measurement discriminative information that UE reports.According to measuring discriminative information presence of intercell interference is suppressed the influence that strategy produces, can obtain the matched curve function by emulation, perhaps obtaining one influences the rank table, this matched curve function or to influence the rank table all be known at UE and NodeB.NodeB can or influence the rank table according to known matched curve function, utilizes and measures discriminative information, takes rational presence of intercell interference to suppress strategy.
Can limit the maximum sub-district of measuring in the embodiment of the invention and report number, and should maximum measure the sub-district by the measurement configuration messages that NodeB sends to UE and report number to be handed down to UE, make UE measure sub-district and report number to determine to report the measured value of several sub-districts according to this maximum.
As shown in Figure 3, the sub-district that surpasses the reporting positioning survey thresholding has 4, and maximumly measures the sub-district to report number be 2, and then UE only reports the measured value of Cell1 and Cell2.And when the sub-district number that surpasses the reporting positioning survey thresholding during smaller or equal to maximum constraints sub-district number, then UE reports all to surpass the measured value of the sub-district of reporting positioning survey thresholding.
The embodiment of the invention can also be added an indication information in the measurement message that is used for the UE location, and whether the sub-district number that indication reaches the reporting positioning survey thresholding surpasses the actual sub-district number that reports.Value that can this indication information is set to: 0 and 1, and wherein, the sub-district number that 0 expression reaches the reporting positioning survey thresholding surpasses the actual sub-district number that reports, and the sub-district number that 1 expression reaches the reporting positioning survey thresholding surpasses the actual sub-district number that reports.When the value of this indication information is 1, can also further indicate the sub-district number that reaches the reporting positioning survey thresholding and the comparison value of the actual sub-district number that reports.
NodeB can select better to disturb between proper cell according to this indication information and suppress strategy.When the sub-district number that reaches the reporting positioning survey thresholding was fewer, NodeB can adopt the interference inhibition strategy that reduces simultaneously the interference of certain several adjacent sub-district.For example: utilize FFR (Fractional Frequency Reuse, partial frequency multiplexing) technology that the subcarrier of several adjacent cell reuse is coordinated to open, reach and disturb the purpose that suppresses.When the sub-district number that reaches the reporting positioning survey thresholding was many, NodeB can select to reduce simultaneously the interference inhibition strategy to the interference of a plurality of adjacent sub-districts.For example: NodeB can adopt power control strategy, suppresses the UE maximum transmission power, thereby reduces the interference to a plurality of adjacent sub-districts simultaneously.
In addition, in the prior art,, not only comprised direct metrical informations such as RSRP, also comprised some other information that is used to switch purpose for to switch to the measurement reporting message of purpose.Such as, mainly comprise with the measurement reporting message that switches to purpose:
{
Cell?Identity
Cell?synchronisation?information
CHOICE?mode
Primary?CPICH?info
RSRP
}
The embodiment of the invention is revised the part field of the measurement message that is used for UE location, and the measurement message being used for the UE location only reports UE to locate needed content, has removed unnecessary redundant information.UE locatees needed content and is mainly:
{
Cell?Identity
RSRP
}
The embodiment of the invention is not limited thereto, and also can locate needed content according to UE, takes other to reduce the message format of redundant information.
For further reducing signaling consumption, can also increase a reporting positioning survey again and stop thresholding: report handover measurement thresholding to stop thresholding, to measure the frequency that reports of discriminative information in the further restriction embodiment of the invention as reporting positioning survey.When reaching reporting positioning survey and stop thresholding, stop to report the measurement message that is used for the UE location.NodeB is directly according to the handover measurement reporting message, and the interference of carrying out the minizone suppresses.
The report method of above-mentioned metrical information, by the measured value of sub-district, UE place and this adjacent cells of cells is adjudicated, obtain to measure discriminative information, and then report this measurement discriminative information, the metrical information feedback mechanism is become measurement decision-feedback mechanism, effectively reduced signaling consumption, also fully utilized all metrical informations that UE measures simultaneously, improved the UE locating information amount that is used for presence of intercell interference inhibition strategy, more helped NodeB and take rational presence of intercell interference to suppress strategy.
As shown in Figure 4, flow chart for the report method of another metrical information of the embodiment of the invention, for ICIC (Inter-cell Interference Coordination, stride coordinating district interference) situation, UE does not require switching, do not need to consider performance of handoffs, so also there is not the problem with the measurement priority of frequency or alien frequencies, promptly adjacent sub-district requires all measuring with the signal quality of frequency and alien frequencies.Specifically may further comprise the steps:
Step S401, network side are to UE sending measuring control messages, and this measurement control messages comprises measurement type, reporting event and reporting format, the filter value of setting and the measurement clearance of setting.For the signal quality measured of ICIC and reporting, network side need define the new parameter of a cover and use for UE.The parameter of redetermination comprises:
A) measure type: area interference is measured.The measurement type of having determined among the LTE (Long Term Evolution, Long Term Evolution) has at present: with frequency, alien frequencies and different system.Relevant with ICIC is signal quality measured with frequency and alien frequencies.When triggering the ICIC measurement, UE need all measure the same frequency of neighbor cell and the signal quality of alien frequencies.The same frequency of this and HO (Handover switches) or alien frequencies signal quality measured also different because under the situation of HO, are always measured with signal quality frequently earlier, if all not all right with signal quality frequently, measure the signal quality of alien frequencies again.Therefore the embodiment of the invention has defined a kind of new measurement type: area interference is measured, and is used for the signal quality under the ICIC situation is measured.
B) report criterion and reporting format.The report criterion of embodiment of the invention redetermination comprises measures discriminative information, buffer status, UL (Uplink, up link) one or more in permission, DL (Downlink, down link) permission, UL data volume, DL data volume, timer and the periodic report mode.Wherein, permission of the UL in this report criterion or DL permission are specially: permission resource frequency, resource continuous time of permission and permission stock number.When UE does not have the UL permission, then use a timer to trigger.The criterion of report criterion in the embodiment of the invention and former WCDMA (Wideband Code Division MultipleAccess, Wideband Code Division Multiple Access (WCDMA)) is different, and the incident of WCDMA all is to consider single situation, such as signal quality or buffer status etc.And the report criterion of redetermination is a comprehensive report criterion in the embodiment of the invention.In addition, except new report criterion, the embodiment of the invention has also defined new reporting format, and described reporting format comprises that whether sub-district number that measured value, the number of cells that reports, cell ID and indication reach the reporting positioning survey thresholding surpasses one or more in the indication information of the actual sub-district number that reports.The measured value of UE can be RSRP, RSSI or RSRQ etc., and the measurement bandwidth of obtaining the UE measured value can be part bandwidth or whole bandwidth of sub-district.The sub-district number that reports can adopt and report thresholding, report number, or the mode of both combinations.
C) filter setting: measure the assessment filter for respectively be provided with frequency, alien frequencies and different system in the LTE system at present.For HO, switch for fear of frequent switching and table tennis, filter is set, can make that the measurement discriminative information of assessment is relatively reliable and stable.But, need make and measure discriminative information in time, effectively by filter is set for ICIC.Think that the filter that ICIC is provided with is different from the filter that is provided with for switching.
D) measurement clearance: for switching, time requirement is more urgent, because if untimely switching, UE may call drop, influences user's impression.May lack relatively so measure the cycle that is provided with of time slot, make UE can report the proper cell that finds as early as possible.And for ICIC, be not very urgent to the requirement of time, but wish that UE measures the signal quality of adjacent sub-district fully, provide the disturbed condition of complete adjacent sub-district.Think that the measurement time slot that ICIC is provided with also is different from the measurement time slot that is provided with for switching.
Step S402, UE carries out the homogenous frequency signal mass measurement, and filter value of setting of utilizing the measurement control messages to carry is assessed the common frequency measurement value.When the measured value of assessing out satisfy to be measured the report criterion that control messages issues, wherein report the situation that criterion comprises common frequency measurement discriminative information, buffer status and UL permission.When there was the UL permission in UE, UE utilized the ascending resource of this UE application, reports reporting event; Timer or periodic report mode can also be set, and when timer expiry or when reaching report cycle, UE reports reporting event voluntarily.
Step S403, UE is according to measuring reporting format that control messages issues to NodeB reporting measurement result.Wherein Bao Gao form comprises measuring amount and cell identity information and the information such as sub-district number that report.
Step S404, NodeB judge whether measuring frequency and this cell frequency have the crossover part.If frequency has the crossover part, execution in step S405 then; If frequency does not have the crossover part, execution in step S406 then.
Step S405, NodeB are that UE distributes measurement clearance, and it is signal quality measured that UE is carried out on the measurement clearance of distributing.
Step S406, it is signal quality measured that UE carries out alien frequencies, and filter value of setting of utilizing the measurement control messages to carry is assessed the different-frequency measure value.When the measured value of assessing out satisfy to be measured the report criterion that control messages issues, wherein report the situation that criterion comprises common frequency measurement discriminative information, buffer status and UL permission.When there was the UL permission in UE, UE utilized the ascending resource of this UE application, reports reporting event; When UE does not have the UL permission, timer is set, when timer expiry, UE reports reporting event voluntarily.
Step S407, UE is according to measuring reporting format that control messages issues to NodeB reporting measurement result.The reporting format information such as sub-district number that comprise measured value, cell identity information and report wherein.
As shown in Figure 5, the structure chart for the reporting system of embodiment of the invention metrical information comprises:
