Description
Technical field
The present invention relates to the communications field, measure the startup method and the subscriber equipment of task in a kind of multicarrier.
Background technology
In the LTE system under connected state, the detailed process of measuring is: network side will be measured control messages and send to UE, wherein, comprise other association attributeses of measuring sign, measuring object, report configuration and measuring in this measurement control messages, measure sign measuring object and report configuration association are got up to form a complete measurement task.Measuring object has comprised the measuring object attribute (as carrier frequency, Neighboring Cell List etc.), each carrier frequency only can dispose a measuring object, and the report configuration has comprised the report configuration attribute (as Event triggered or periodic report, the event definition (A1, A2...) that triggers reports number of times etc.).UE goes to carry out and measures and assessment according to measuring measuring object, report configuration in the control messages, and generates measurement report according to measurement result and report network side.The measurement report that network side reports according to UE carries out switch decision and Inter-Cell Interference Coordination (Inter-cell Interference Coordination abbreviates ICIC as), and wherein ICIC only carries out at homogeneous-frequency adjacent-domain.
For the measurement task of Event triggered, when being equal to or greater than TTT (Time ToTrigger), the duration that measuring object satisfies the entry criteria (being better than thresholding such as neighboring cell signal quality) of incident just is considered to satisfy the measuring object of trigger conditions.Satisfy the trigger condition of incident as measuring object after, reporting measurement reports is given network side, and reporting measuring object in the report is that measuring amount according to network settings sorts, optimum in front.For ICIC, when satisfy when leaving condition the sub-district of satisfying the incident entry criteria, also reporting measurement reports, network side carries out ICIC according to this information, reportOnleave distinguishes in configuration by measuring for this, promptly when reportOnleave be TRUE, UE need the sub-district satisfy leave condition in reporting measurement reports, just the measurement task of incident A3 has this characteristic at present.
In the current agreement, the prerequisite of the same frequency of UE startup network side configuration, alien frequencies, isosystem measurement is, s-measure (value of the RSRP of an appointment) is configuration not, perhaps disposed s-measure simultaneously the RSRP of Serving cell through the filtration of layer three after (being called s-Serving) lower than s-measure.The purpose of current configuration s-measure is the frequency of to measure and reporting in order to reduce.If disposed s-measure, s-Serving is higher than s-measure always simultaneously, and UE does not start the measurement task of network side configuration so, as shown in Figure 1.
For higher data rate is provided to the mobile subscriber, advanced long-term evolution system (LongTerm Evolution Advance, abbreviation LTE-A) carrier aggregation technology (CarrierAggregation has been proposed, be called for short CA), its objective is to the UE with respective capabilities provides bigger broadband, improve the peak rate of UE.Among the LTE, the maximum downstream transmission bandwidth of system's support is 20MHz, and carrier aggregation is that two or more component carrier (ComponentCarriers is called for short CC) polymerization are got up to support that maximum is no more than the transmission bandwidth of 100MHz greater than 20MHz.The frequency range that component carrier can use LTE to define also can be used the newly-increased specially frequency range as LTE-A.Based on present frequency spectrum resource anxiety, can not always have component carrier continuous on the frequency domain can distribute to operator and use, so whether carrier aggregation is continuous on frequency domain by each component carrier, can divide continuous carrier aggregation and discrete carrier aggregation.Carrier aggregation by each component carrier whether in identical frequency band, the carrier aggregation and the carrier aggregation of striding frequency band (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.LTE-AUE with carrier aggregation ability, transceive data on a plurality of component carriers simultaneously, the UE that below relates to is this type of UE except specifying.In the LTE-A system, UE can pass through a plurality of component carriers (as CC1 after entering connected state simultaneously, CC2) communicate with source base station, the base station can or be decided to be UE approximately according to agreement by explicit configuration and specify a principal component carrier wave (PrimaryComponent Carrier, abbreviate PCC as), other component carrier is called auxilliary component carrier (Secondary Component Carrier, abbreviate SCC as), Serving cell on DL PCC is called main Serving cell (Primary Cell, abbreviate Pcell as), Serving cell on DL SCC is called auxilliary Serving cell (Secondary Cell abbreviates Scell as).NAS information (as information such as ECGI, TAI) is obtained by Pcell, if RLF takes place DL PCC, UE need carry out the RRC process of reconstruction.After UE entered connected state from IDLE attitude access network, the CC of access was PCC.UE is in connected state, and network can change the transfer process of finishing Pcell by RRC reprovision or intra-cell, and perhaps network side is specified Pcell in the process that notice UE switches.
In the measurement event that has defined, the measurement task of part Event triggered is carried out measurement event when assessment need be to be configured to the signal quality of the component carrier of UE as a reference, as incident A3 (signal quality of abutting subdistrict is higher than the skew of an appointment than the signal quality of Serving cell), for this type of common frequency measurement task, with the signal quality of the Serving cell on the component carrier that has been configured on this frequency (being reference cell) as a reference, promptly be higher than the entry criteria that this abutting subdistrict when specifying Offsets satisfies incident A3 than the signal quality of corresponding component carrier when the signal quality of abutting subdistrict.For this type of different-frequency measure task, can be as a reference with the signal quality of Pcell, perhaps the signal quality of the component carrier of appointment as a reference, promptly when the signal quality of abutting subdistrict than Pcell or when specifying the signal quality of Serving cell on the component carrier to be higher than to specify Offsets this abutting subdistrict satisfy the entry criteria of incident A3.(signal quality of Serving cell is lower than appointed threshold 1 to incident A5, the signal quality of abutting subdistrict is higher than appointed threshold 2), incident B2 (signal quality of Serving cell is lower than appointed threshold 1, and the signal quality of different system abutting subdistrict is higher than appointed threshold 2) and incident A3 are similar.It is not need reference cell that the measurement task of part Event triggered is carried out the Measuring Time assessment, as incident A1 (signal quality of Serving cell is higher than appointed threshold), incident A2 (signal quality of Serving cell is lower than appointed threshold), incident A4 (signal quality of abutting subdistrict is higher than appointed threshold), incident B1 (signal quality of different system abutting subdistrict is higher than appointed threshold).The period measurement task also is not need reference cell.The startup that it should be noted that the measurement task of incident A1 and A2 is not controlled by s-measure, because incident A1 and A2 measure Serving cell, therefore as long as the measurement task has disposed, is just measuring always, has deleted up to the measurement task.
For the measurement task of incident A3, defined two classes at present, a class is that the carrier frequency of measuring object is the carrier frequency of SCC, reference cell is the Scell identical with the carrier frequency of measuring object, is called with A3 incident frequently.The carrier frequency that an other class is a measuring object is all possible carrier frequency, comprises the carrier frequency of SCC, and reference cell is Pcell, is called A3-PCC.
