Description
Technical field
The present invention relates to moving communicating field, relate in particular to the processing method of measuring configuration in a kind of carrier aggregation (carrier aggregation is called for short CA).
Background technology
In mobile communication system, in order to satisfy the mobility requirement, when subscriber equipment (User Equipment is called for short UE) after certain sub-district and network connect, UE still needs the signal quality of its Serving cell and neighbor cell is measured, so that select proper cell to switch.With EUTRAN (Evolved Universal Terrestrial Radio Access Network, evolved Universal Terrestrial Radio Access Network network) be example, the detailed process that UE measures under the connected state is: network side will be measured control messages and send to UE, wherein, comprise the attribute of measuring sign (measurement identity abbreviates MID as), event type, measuring object and needing to measure in this measurement control messages; UE carries out parameter initialization according to the measurement sign of measuring in the control messages, and obtains each measuring object attribute and the measurement result separately in whole measuring objects of measuring in the control messages; UE carries out the incident assessment according to initialized parameter or predetermined threshold to the measurement result of each measuring object, and the duration by assessing the trigger condition of determining to satisfy in whole measuring objects measurement event is more than or equal to the measuring object of scheduled measurement triggered time length (Time To Trigger abbreviates TTT as); UE puts into these measuring objects (this moment, measuring object corresponded to the sub-district) that satisfy trigger conditions the cell list (cellsTriggeredList) of the measurement sign of this incident correspondence; UE generates measurement report and measurement report is sent to network side according to the measurement result of the measuring object of determining, the measuring object that is comprised in the measurement report all is to obtain from the cell list of the measurement sign of this incident correspondence.
In mobile communication system, measuring object is a unit with frequency or the cell set that is positioned at frequency, measuring configuration comprises and (for example measures form that sign, measuring object, measurement report, Event triggered or periodic report) etc., wherein, measure sign and report structure (reporting configuration, the attribute that expression reports) corresponding to a certain measuring object (measurement object) and specific measurement, the different measuring of same measuring object reports the corresponding different measurement of structure to identify.Measurement configuration for event type, measurement reports structure corresponding one by one with measurement event (this moment one measure sign described a measuring object and corresponding with it measurement event), and the present measurement event that defines generally comprises the duration of trigger condition of lag parameter Hys, incident of the trigger condition of incident, the certain threshold Thresh that leaves condition, incident, incident and the side-play amount Offset of incident etc.
In order to satisfy the mobility requirement of UE under the connected state, require UE that the measuring object that satisfies trigger conditions is measured and reported to Serving cell and adjacent sub-district, some measurement event have been defined at present to Serving cell, for example, the trigger condition of definition measurement event is that the signal quality of Serving cell is higher than predetermined threshold, or the signal quality of Serving cell is lower than predetermined threshold; To the measurement event of adjacent sub-district, for example, the trigger condition of definition measurement event is that the signal quality of adjacent sub-district is higher than a certain threshold value, or the signal quality of adjacent sub-district is than the high predetermined side-play amount of signal quality of current service cell.
For the measurement report of Event triggered, have two kinds to report form: a kind of is that the Event triggered single reports the measurement report of Event triggered (or be called); Another kind is that Event triggered periodically reports.The Event triggered single reports and is meant that network side has disposed the trigger condition of incident for certain UE, after UE detection and assessment measuring object satisfy the trigger condition of incident, the measuring object that satisfies trigger conditions is put into the cell list of the measurement sign of this incident correspondence, only report the one-shot measurement report, the measuring object that this report comprises all obtains from cell list.If in certain time of back, there is new measuring object to satisfy the trigger condition of this incident again, UE puts into new measuring object the cell list of the measurement sign of this incident correspondence, report simultaneously new measurement report once more, the measuring object that new measurement report comprises all from this moment cell list obtain, report this moment number of times still for once.
Event triggered periodically reports and is meant that network side has disposed the trigger condition of incident for certain UE, after UE detection and assessment measuring object satisfy the trigger condition of incident, the measuring object that satisfies trigger conditions is put into the cell list of the measurement sign of this incident correspondence, reporting measurement reports repeatedly, the times of reporting and the time interval dispose by network side, and the measuring object that the measurement report that at every turn reports comprises all is to obtain from the current cell list that gives the correct time.In the process that this repeatedly reports or after repeatedly reporting end, if there is new measuring object to satisfy the trigger condition of incident, UE reports number of times with replacement, new measuring object is put into the cell list of the measurement sign of this incident correspondence, according to the time interval of setting with report the orderly once more reporting measurement result of number of times, the measuring object that each measurement report comprises all is to obtain from the current cell list that gives the correct time then.
To the measurement of measuring object, different systems adopts different method of measurement, all is signal qualitys of reflection sub-district.In LTE, UE measures is the power (Reference Signal Received Power abbreviates RSRP as, and unit is dBm) of the reference signal that receives or quality (the Reference Signal Received Quality of the reference signal that UE receives, abbreviate RSRQ as, unit is dB).In WCDMA, that UE measures is received power (the Received Signal Code Power of Common Pilot Channel, be called for short RSCP, unit is dBm) or the Ec/No of Common Pilot Channel (refer to behind the transmitting terminal spread spectrum on every code channel the energy of each chip and the ratio of band limited white noise power spectral density), unit is dB.UE needs the measurement result of more same type when comparing the signal quality of different districts.When the assessment measuring object satisfies trigger conditions, complete description to this measuring object not only comprises RSRP or the RSRQ that UE records, specific side-play amount (the frequency specific offset of frequency that also comprises this measuring object, abbreviation Ofn), specific side-play amount (the cell specific offset in sub-district, be called for short Ocn), with the A4 incident that defines among the LTE is example: the signal quality of adjacent sub-district is higher than a certain threshold value, its concrete mathematical description is Mn+Ofn+Ocn-Hys＞Thresh, and Mn is RSRP or the RSRQ that UE records adjacent sub-district in the formula.
In order to satisfy people to the demand of high bandwidth more, LTE Advance proposes the purpose of the bigger bandwidth of method realization of employing carrier aggregation, this moment, (each carrier wave was called component carrier by a plurality of continuous or discrete carrier waves in a sub-district, Component Carrier) forms, the service of multicarrier can be provided for UE simultaneously.Component carrier can adopt the carrier wave of compatible LTE system, and this carrier wave is called the backward compatibility carrier wave; Component carrier also can adopt the carrier wave of incompatible existing LTE system, and this carrier wave is called non-backward compatible carrier waves, and this carrier wave can only be that Release 10 versions and above UE use.Component carrier can become the specific anchor carrier wave in sub-district (cell specific anchor carrier), also can become the specific anchor carrier wave of user (UE specific anchor carrier).If only at one-component carrier wave transmitting system message, beep-page message etc., this component carrier becomes the specific anchor carrier wave in sub-district; If a plurality of component carriers all can transmitting system message, beep-page message etc., just there is not the specific anchor carrier wave in sub-district of typical meaning this moment, for the subscriber equipment of connected state, certain component carrier of its work can become the specific anchor carrier wave of user.For the subscriber equipment of connected state, a plurality of component carriers of its work (receiving or send signaling or data at these carrier waves) are called activation carrier wave collection (active carriers) or service carrier wave collection.
Whether carrier aggregation is continuous on frequency domain by each component carrier, can divide continuous carrier aggregation and discrete carrier aggregation, and so-called continuous carrier aggregation is meant that each component carrier is interconnective on frequency domain; Discontinuous carrier aggregation then refers to it is unconnected between each component carrier on frequency domain.Carrier aggregation by each component carrier whether in identical frequency band, the carrier aggregation and the carrier aggregation of striding frequency band (over multiple frequency bands) that can be divided into single band (single band), so-called single carrier aggregation is meant all component carriers that participate in carrier aggregation all in same frequency band, and single carrier aggregation can be that continuous carrier aggregation also can be discontinuous carrier aggregation; The carrier aggregation that what is called is striden frequency band is meant that the component carrier that participates in carrier aggregation can be derived from different frequency bands.
In carrier aggregation, still need to satisfy the mobility demand, still needing network side is that UE implements to measure configuration, yet the configuration of many measurement event is measurement target or references object with Serving cell (having only a carrier wave) all in the measurement of the existing LTE configuration, adopt the sub-district of carrier aggregation that a plurality of carrier waves are arranged, existing measurement configuration can not be applied to the sight of multicarrier, therefore in LTE-A, subscriber equipment works under the situation of multicarrier, how to select references object or measurement target, the measurement configuration of how to dispose this moment is a problem of needing solution badly.

Embodiment
The present invention is applied to mobile communication system, comprises at least one base station and a UE, and UE is in connection status in the sub-district of carrier aggregation that the base station is had jurisdiction over.
In the present invention, described UE is known one or more witness mark component carriers of configuration;
Described UE receives the measurement configuration that comprises the measurement event that is applied to described one or more witness mark component carriers that send described base station, carries out according to described measurement configuration and measures.
The present invention is described in detail below in conjunction with drawings and the specific embodiments.
As shown in Figure 1, the embodiment of the invention comprises the steps:
Step 101, base station and the UE described one or more witness mark component carrier of having made an appointment, perhaps the information of the described one or more witness mark component carriers of UE is informed in the base station;
Step 102, the measurement configuration that the base station sends to UE comprises in the described measurement configuration: the measurement event that is applied to described one or more witness mark component carriers;

The present invention is further described with concrete application example below:
Use example one
In LTE Advance system, there is the S1 interface referring to Fig. 2 in the schematic diagram of its network topology between core net and base station (macro base station), has X2 interface between the adjacent base station; Home eNodeB can directly link to each other with core net, also can link to each other with core net by femto gateway, does not have X2 interface between the Home eNodeB and between Home eNodeB and the macro base station.UE is arranged in the sub-district of carrier aggregation that macro base station is had jurisdiction over, and is in idle condition.The component carrier that the sub-district of this carrier aggregation comprises is the component carrier of three continuous 20M Hz in frequency band 1 (Band1, up UL 1920～1980M Hz, descending DL 2110～2170M Hz).The equal transmitting system message of these three carrier waves, beep-page message.
Sometime, UE initiates to insert at random at component carrier (UL 1920～1940, and DL 2110～2130), successfully inserts the sub-district of this carrier aggregation.Because UE supports that the service traffics of multicarrier and UE are very big, component carrier (UL 1940～1960, and DL 2130～2150) has been distributed for UE again in the base station, and promptly this moment, UE used two component carriers simultaneously, is called two service carrier waves or two activation carrier waves.
Owing to be single carrier aggregation, and each component carrier has identical coverage, so base station selected one of them component carrier is as the witness mark component carrier, the base station sends to UE and measures configuration (by RRC Connection Reconfiguration), this measurement configuration comprises a witness mark component carrier, and (UL 1920～1940, DL 2110～2130), measure the absolute wireless frequency number of channel that only need indicate upstream or downstream in the configuration (Absolute Radio Frequency Channel Number, ARFCN-ValueEUTRA), perhaps indicate be first component carrier (from low to high; If adopt rule from high to low, then be the 3rd component carrier); It is the witness mark component carrier that network also can adopt the setting of acquiescence promptly to insert successful carrier wave at random, measures the clear and definite information that does not just comprise the witness mark component carrier in the configuration this moment.Measure to comprise in the configuration and measure sign 1, measure sign 2, measure sign 3, measure sign 4.
Wherein measure sign 1 corresponding witness mark component carrier (for the UE of Release 8, the witness mark component carrier is exactly a Serving cell) place frequency and measurement event A1, A1 is that the signal quality of witness mark component carrier is higher than predetermined thresholding;
Measure sign 2 corresponding witness mark component carrier place frequency and measurement event A2, A2 is that the signal quality of witness mark component carrier is lower than predetermined thresholding;
Measure sign 3 corresponding witness mark component carrier place frequency and measurement event A3, this moment, A3 be the side-play amount of being scheduled to than the signal quality height of witness mark component carrier with the signal quality of the neighbor cell (ARFCN of these neighbor cells and witness mark component carrier is identical) of witness mark component carrier same frequency;
Measure sign 4 respective frequencies f1 and measurement event A3, this moment, A3 was the signal quality high side-play amount of being scheduled to of the signal quality of the neighbor cell (neighbor cell for carrier aggregation is an adjacent carrier) that is positioned at frequency f 1 than witness mark component carrier.
After UE receives and measures configuration, measurement sign is wherein carried out parameter initialization, and obtain each measuring object attribute and the measurement result separately in whole measuring objects of measuring in the configuration; UE carries out the incident assessment according to initialized parameter or predetermined threshold to the measurement result of each measuring object.UE determines the witness mark component carrier of measurement event correspondence, and the measuring object of trigger conditions is satisfied in assessment, triggers reporting measurement reports.Such as identifying 3 for measuring, UE determines the witness mark component carrier of measurement event A3 correspondence, the measuring object (promptly existing the new neighbor cell with the same frequency of witness mark component carrier to satisfy the A3 incident) of this trigger conditions is satisfied in assessment, if there is new neighbor cell to satisfy the A3 incident herein more than or equal to TTT (new neighbor cell is meant and is not included in the measuring object of measuring in the tabulation of sign 3 corresponding district), UE generates measurement report according to rule, and measurement report is sent to the base station.The base station is implemented the scheduling of UE according to measurement report or is made handover decisions.
Need to prove that network can dispose when the allocating and measuring incident: with witness mark component carrier incident relatively; The incident that does not need comparison.With witness mark component carrier incident relatively such as incident A3, A5, B2; The incident A4, the B1 that do not need comparison.Network can be specified unique measurement target (frequency) when configuration A1, A2 incident, therefore the witness mark component carrier can be set (for the consistency that illustrates for A1, A2 incident, define A1 in this manual, the A2 incident has all adopted the witness mark component carrier), then need clear and definite witness mark component carrier for A3, A5, B2 incident.
Use example two
In LTE Advance system, there is the S1 interface referring to Fig. 2 in the schematic diagram of its network topology between core net and base station (macro base station), has X2 interface between the adjacent base station; Home eNodeB can directly link to each other with core net, also can link to each other with core net by femto gateway, does not have X2 interface between the Home eNodeB and between Home eNodeB and the macro base station.UE is arranged in the sub-district of carrier aggregation that Home eNodeB is had jurisdiction over, and is in idle condition.(Band 1 at frequency band 1 for the component carrier that the sub-district of this carrier aggregation comprises, UL 1920～1980M Hz, DL 2110～2170M Hz) and frequency band 2 (Band 2, UL 1850～1870M Hz, DL 1930～1950) in, be the component carrier of 4 discontinuous 20M Hz.Have only three component carrier transmitting system message, beep-page message among the Band 1 in these four carrier waves.
Sometime, UE initiates to insert at random at component carrier (UL 1920～1940, and DL 2110～2130, and this carrier wave is called CC1), successfully inserts the sub-district of this carrier aggregation.Because UE supports that the service traffics of multicarrier and UE are very big, (UL 1940～1960 for UE has distributed component carrier again in the base station, DL 2130～2150, this carrier wave is called CC2) and (UL 1850～1870M Hz, DL 1930～1950, this carrier wave is called CC3), promptly this moment, UE used three component carriers simultaneously, was called three service carrier waves or three activation carrier waves.
Owing to be the carrier aggregation of striding frequency band, and each component carrier has identical coverage in each frequency band, so each frequency band of base station selects the one-component carrier wave as the witness mark component carrier, the base station sends to UE and measures configuration (by RRC Connection Reconfiguration), this measurement configuration comprises two witness mark component carriers (CC1 and CC3), measure the absolute wireless frequency number of channel that only need indicate upstream or downstream in the configuration (Absolute Radio Frequency Channel Number, ARFCN-ValueEUTRA), perhaps indicate is first and second component carrier (from low to high); Certain carrier wave that also can adopt the method (mode of promptly making an appointment) of implicit expression to set different frequency bands (Band) is that the witness mark component carrier is (such as can being that the minimum carrier wave of Band 1 and Band 2 frequencies is the witness mark component carrier herein, be CC1 and CC3), measure the independent information that does not just comprise the witness mark component carrier in the configuration this moment.Measure to comprise in the configuration and measure sign 1 to measuring sign 8.
Wherein measure sign 1 corresponding witness mark component carrier CC1 place frequency and measurement event A1, A1 is that the signal quality of witness mark component carrier CC1 is higher than predetermined thresholding;
Measure sign 2 corresponding witness mark component carrier CC1 place frequency and measurement event A2, A2 is that the signal quality of witness mark component carrier CC1 is lower than predetermined thresholding;
Measure sign 3 corresponding witness mark component carrier CC3 place frequency and measurement event A2, A2 is that the signal quality of witness mark component carrier CC3 is lower than predetermined thresholding;
Measure sign 4 corresponding witness mark component carrier CC1 place frequency and measurement event A3, this moment, A3 be the side-play amount of being scheduled to than the signal quality height of witness mark component carrier CC1 with the signal quality of the neighbor cell (ARFCN of these neighbor cells and witness mark component carrier CC1 is identical) of witness mark component carrier CC1 same frequency;
Measure sign 5 corresponding witness mark component carrier CC3 place frequency and measurement event A3, this moment, A3 be the side-play amount of being scheduled to than the signal quality height of witness mark component carrier CC3 with the signal quality of the neighbor cell (ARFCN of these neighbor cells and witness mark component carrier CC3 is identical) of witness mark component carrier CC3 same frequency;
