Description
Technical field
The present invention relates to the multi-carrier communication technical field, relate in particular to a kind of multi-carrier communications systems, and the method that starts the measurement task in the carrier aggregation of multi-carrier communications systems.
Background technology
In the Long Term Evolution LTE system, the detailed process of measuring under connected state is: network side will be measured control messages and send to user equipment (UE) (User Equipment), wherein, comprise in this measurement control messages: other association attributeses of measuring sign (MID), measuring object (MO), report configuration (RC) and measuring.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, (Inter-cell InterferenceCoordination, ICIC), wherein ICIC only carries out at homogeneous-frequency adjacent-domain to carry out switch decision and Inter-Cell Interference Coordination.Wherein: measure sign measuring object and report configuration association are got up to form a complete measurement task; Measuring object has comprised measuring object attribute (as carrier frequency, Neighboring Cell List etc.), and each carrier frequency only can dispose a measuring object; The report configuration has comprised report configuration attribute (as Event triggered or periodic report, the event definition of triggering (A1, A2...) reports number of times etc.).
For the measurement task of Event triggered, when being equal to or greater than triggered time TTT (Time To Trigger), 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, it is that measuring amount according to network settings sorts that reporting measurement reports is given network side, the measuring object in the measurement report that reports, optimum in front.For switch decision and Inter-Cell Interference Coordination ICIC, when satisfy when leaving condition the sub-district of satisfying the incident entry criteria, also reporting measurement reports, network side carries out switch decision and Inter-Cell Interference Coordination according to this information, reportOnleave distinguishes this characteristic in the configuration by measuring, 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, measurement for Serving cell, UE is carrying out always, but, 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, promptly UE is not to be subjected to s-measure control to the measurement of Serving cell.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 equal to or higher than s-measure always simultaneously, and UE does not start the measurement task of network side configuration so.Above-mentioned common frequency measurement refers to the carrier frequency measurement task identical with the descending carrier frequency of Serving cell of measuring object, the carrier frequency that different-frequency measure refers to measuring object is a measurement task different with the descending carrier frequency of Serving cell in the LTE system, above-mentioned both belongs to measurement in the system, the carrier frequency that isosystem measurement refers to measuring object is UTRA, perhaps GERAN, perhaps the carrier frequency of CDMA2000 belongs to system's measurements.
For the demand of common frequency measurement, UE can be in 200ms measure the sub-district of 8 signs and to upper strata feedback measurement result, whether dispose DRX and whether allocating and measuring at interval this demand is had more or less influence.Demand for different-frequency measure, UE can be at most to 3 frequencies in 480*3ms, the sub-district of minimum 4 signs of each frequency is measured and to upper strata feedback measurement result, whether dispose DRX and whether allocating and measuring at interval this demand is had more or less influence.Be separated with two kinds of forms between measurement, a kind of is to be 40ms in the cycle, and gap length is 6ms, and another is to be 80ms in the cycle, and gap length is 6ms.
For higher data rate is provided to the mobile subscriber, advanced long-term evolution system (Long TermEvolution Advance, abbreviation LTE-A) carrier aggregation technology (Carrier Aggregation 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 (Component Carriers 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.LTE-A UE with carrier aggregation ability, transceive data on a plurality of component carriers simultaneously under connected state, the UE that below relates to is this type of UE except specifying.
In the LTE-A system, UE enters and can pass through a plurality of component carriers behind the connected state simultaneously and (as CC1, CC2) communicate with source base station, can identify by component carrier, as CC ID, specifically identify a carrier wave.The base station can or be decided to be UE approximately according to agreement by explicit configuration and specify a principal component carrier wave (Primary Component Carrier, PCC), other component carrier is called auxilliary component carrier (Secondary Component Carrier, SCC), Serving cell on PCC is called main Serving cell (PrimaryCell, be called for short Pcell), the Serving cell on SCC is called auxilliary Serving cell (SecondaryCell is called for short Scell).NAS information (as information such as ECGI, TAI) is obtained by main Serving cell Pcell, if RLF takes place DL Pcell, UE need carry out the RRC process of reconstruction.After UE entered connected state from IDLE attitude access network, the sub-district of access was main Serving cell Pcell.UE is in connected state, and network can change the transfer process of finishing main Serving cell Pcell by RRC reprovision or intra-cell, and perhaps network side is specified main Serving cell Pcell in the process that notice UE switches.Wherein main Serving cell Pcell has only one, and auxilliary Serving cell Scell can not have, and also can have one to a plurality of.Increase, deletion and the replacement of auxilliary Serving cell Scell belongs to the category of component carrier CC management.The measurement report that network side reports according to UE carries out component carrier CC management, and the measuring object that relates to is can carry out the sub-district on the component carrier of polymerization and the adjacent area of same carrier with current service cell.
The intrasystem measurement event of the LTE that has defined is:
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 A3 (signal quality of abutting subdistrict is higher than the skew of an appointment than the signal quality of Serving cell);
Incident A4 (signal quality of abutting subdistrict is higher than appointed threshold);
Incident A5 (signal quality of Serving cell is lower than appointed threshold 1, and the signal quality of abutting subdistrict is higher than appointed threshold 2).
Wherein, incident A4 and Serving cell are irrelevant, so the definition of incident A4 does not change among the LTE-A.Incident A1 and A2 are the measurement event at a Serving cell, and therefore, among the LTE-A, each Serving cell (Pcell and Scell) all can have the measurement task of an incident A1 and A2.
Wherein, there are following two kinds in incident A3: with frequency incident A3 (perhaps being called A3-SCC) and incident A3.
With frequency A3 event definition be, the carrier frequency of measuring object is the carrier frequency at component carrier (PCC and/or the SCC) place of configuration, reference cell is Scell or the Pcell on the corresponding measuring object carrier frequency, (this deviant can be a negative than being higher than the skew of an appointment with the signal quality of the Serving cell of the identical frequency of abutting subdistrict when the signal quality of abutting subdistrict, it also can be positive number, when skew is negative, the definition of A3 incident is, and is lower than the absolute value of the skew of this appointment when the signal quality ratio and the signal quality of the Serving cell of the identical frequency of abutting subdistrict of abutting subdistrict).
The A3 event definition is, the carrier frequency of measuring object is all carrier frequency (carrier frequency that comprise PCC and SCC place), reference cell is Pcell, when abutting subdistrict (if the measuring object carrier frequency be the Scell place carrier frequency so this Scell also treat as abutting subdistrict) signal quality be higher than the skew of an appointment than the signal quality of Pcell (this deviant can be a negative, also can be positive number, detailed directions be with identical with frequency A3 incident).
A5 incident and A3 event class are seemingly, the carrier frequency that is measuring object is all carrier frequency (carrier frequency that comprises PCC and SCC place), reference cell is Pcell, the signal quality of Serving cell is lower than appointed threshold 1, abutting subdistrict (if the measuring object carrier frequency be the Scell place carrier frequency so this Scell also treat as abutting subdistrict) signal quality be higher than appointed threshold 2.
In carrier aggregation, when start the problem of measurement about UE, all measurements are all advocated to start by current a lot of companies when the signal quality of Pcell is lower than s-measure, but there are two problems in this method:
The first, when the signal quality of Pcell was fine, UE was not activated measurement, can't find the interference that current service cell exists, and when particularly existing with frequency pico (Pico cell sub-district) or femto (Home eNodeB) sub-district, problem is particularly serious;
Second, when the signal quality of Pcell is fine, UE is not activated measurement, the demand that have Scell to increase or replace this moment, the base station does not have measurement report as a reference, can only blindly select Scell to add, and the Scell that selects may be not suitable for carrying out polymerization, need change a Scell again and add, have a plurality of space interface signalings like this and just can finish Scell increase or replacement alternately.Perhaps the base station all disposes the Scell that can carry out polymerization to UE, delete again according to the measurement report of Serving cell then, only according to the signal quality of Serving cell decide which sub-district be fit to carry out polymerization be have circumscribed, it is the disturbed condition that this Serving cell can not be known in the base station, the signal quality of possible certain sub-district is fine, but disturb also very greatly,, can not get a desired effect even this sub-district is increased to UE.
Generally speaking, adopt said method to carry out the carrier management poor efficiency, and can't in time solve the interference problem of Serving cell, thereby, how in time to start the particular measurement task is measured, become the technical issues that need to address at multi-carrier communications systems.

Wherein, described indication information can also be the attribute of whether immediately intrasystem measurement task being measured that increases in measuring the attribute that starts thresholding s-measure, it is in system's measurements task or the system and system's measurements that indication measurement starts the relevant measurement task scope of thresholding s-measure, start judgement according to measuring startup thresholding s-measure, measurement task in the system is then carried out immediately measured.
Described measurement task is the measurement task that is used for the component carrier management, perhaps is used for the measurement task of switch decision and Inter-Cell Interference Coordination ICIC, is other measurement task that need carry out measurement at once.
Described measurement task is to support the measurement task of the component carrier correspondence of carrier aggregation, or the measurement task carried out immediately of the need of corresponding other carrier wave.
Start the method for measurement task in a kind of carrier aggregation of the present invention, comprising:
The base station issues the indication information of the measurement task that need carry out measurement immediately to subscriber equipment;
After described subscriber equipment is received the measurement task and/or received described indication information,, the need of indicating are carried out immediately the measurement task of measurement and carry out measurement immediately in described indication information according to described indication information.
Described indication information is a component carrier information of supporting carrier aggregation, or the measuring object tabulation, or measures identification list.The need of indicating in described indication information are carried out the measurement task of measurement immediately, be that measuring object is a measurement task of supporting the component carrier of carrier aggregation, perhaps measuring object is present in the measurement task in the measuring object tabulation, perhaps measures sign and is present in the measurement task of measuring in the identification list.
The component carrier information of described support carrier aggregation comprises: frequency band and/or carrier frequency and/or component carrier identification information; Described base station is by system message or radio resource control signaling, and the component carrier information of described support carrier aggregation is handed down to subscriber equipment.Also can send described measuring object tabulation or measure identification list to user equipment (UE) by the radio resource control RRC signaling, notifying UE to need to carry out the measurement task of measuring immediately has which.
Described indication information is to be configured in the information of measuring in the control messages, this indication information is at measuring object or measures the attribute information that increases in the sign be used to indicate subscriber equipment whether this measuring object or the corresponding measurement task of measurement sign are needed to carry out immediately measurement.Described subscriber equipment judges that according to indication information the indication information in measuring object or the measurement sign is designated as measurement immediately, then the measurement task that is instructed to is measured immediately; Otherwise described subscriber equipment is just carried out corresponding measurement task when the signal quality of main Serving cell Pcell is lower than measurement startup thresholding s-measure.
Described indication information is the attribute of whether immediately intrasystem measurement task being measured that increases in measuring the attribute that starts thresholding s-measure, it is in system's measurements task or the system and the measurement task between system that indication measurement starts the relevant measurement task scope of thresholding s-measure, when the relevant measurement task scope of i.e. measurement startup thresholding s-measure is system's measurements task, measurement task in the system is then carried out measurement immediately, and to the measurement task between system, then will be lower than at the signal quality of main Serving cell Pcell to measure and just carry out measurement when starting thresholding s-measure; When measure starting the relevant measurement task scope of thresholding s-measure and be system in,, be lower than at the signal quality of main Serving cell Pcell and just carry out measurement when measuring startup thresholding s-measure in the system and system's measurements task with system's measurements task.
Processing according to current wireless resource control RRC agreement can have following several specific implementation method.
First kind, the base station will support the component carrier information of carrier aggregation to notify UE as indication information, indicate, and UE ignores the restriction of s-measure after receiving these pairing measurement tasks of component carrier of supporting carrier aggregation, carry out corresponding the measurement at once.
Described component carrier information comprises frequency band and/or carrier frequency information and/or component carrier identification information; Issue a notice the component carrier information of described support carrier aggregation to subscriber equipment by system message or by radio resource control signaling in described base station.The pairing measurement task of the component carrier of described support carrier aggregation refers to measuring object and supports the measurement task of the component carrier of carrier aggregation for these.In this kind execution mode, as long as network side has disposed the measurement task of measuring object for these component carriers, UE just can carry out measurement immediately to the measurement task of these component carriers.
Second kind, indicate by the configuration information of measuring task the base station, refers to the base station by increase the indication of whether immediately this measurement task being measured in measuring object MO, and described indication information can be TRUE, or TRUE/FALSE.In this way, if the base station configuration of network side be designated as TRUE in this measuring object, expression UE receives the measurement task that this measuring object is relevant, ignores the restriction of s-measure and carries out measurement at once; The indication value is FALSE maybe during this indication vacancy, and UE receives the measurement task that this measuring object is relevant, just carries out in the time of need being lower than measurement startup thresholding s-measure at the signal quality of main Serving cell Pcell.
The third, indicate by the configuration information of measuring task the base station, refer to the base station and increase indication (as TRUE by measuring among the sign MID, or TRUE/FALSE) notifies UE, as long as network side has disposed this and has indicated whether that the cell of carrying out immediately is masked as the measurement task of the MID of TRUE, after UE receives described measurement task, ignore the restriction of s-measure and carry out measurement at once.At this moment, the indication information of whether immediately the measurement task being measured in the described configuration information, be configured in and measure among the sign MID,, indicate the corresponding measurement task of this measurement sign whether to measure immediately by in measuring sign, increasing the attribute of whether immediately the measurement task being measured.Wherein, when this was designated as TRUE, expression UE received that this measurement task ignores the restriction of s-measure and carry out measurement at once; This indication is during vacancy or be FALSE, just carries out when needing the signal quality of Pcell to be lower than s-measure.
The 4th kind, the base station starts thresholding s-measure attribute increase indication (as TRUE by measuring, or TRUE/FALSE) notifies UE, when being designated as TRUE, after UE receives measurement task in the described system (comprising common frequency measurement and different-frequency measure), ignore the restriction of s-measure and carry out measurement at once, when indicating vacancy or being FALSE, for the measurement of the measurement task in the system and between system, the signal quality that need satisfy Pcell just starts when being lower than s-measure.
The indication information of whether immediately the measurement task being measured in the described configuration information, be configured in the s-measure parameter information, by in the configuration information of s-measure, increasing the attribute of whether immediately the measurement task being measured, the measurement task scope that indication s-measure is relevant be system in measurement task or the system with system's measurements task, the described TRUE that is designated as, the relevant measurement task scope of s-measure of expression Set For Current is system's measurements task, be that UE is when receiving in the system measurement task, ignore s-measure and carry out measurement at once, measurement task between system then just starts measurement when the Pcell signal quality is lower than s-measure.
When if the Pcell signal quality is higher than s-measure, the demand of measurement task in the UE executive system, in the time of can being lower than s-measure than Pcell signal quality, the demand of measurement task is loose in the UE executive system.When promptly if the Pcell signal quality is lower than s-measure, the demand of common frequency measurement task is that UE measures the sub-district of 8 signs in 200ms and to upper strata feedback measurement result in the UE executive system, when the Pcell signal quality is higher than s-measure so, in the UE executive system demand of common frequency measurement task can relax for, to less than 8 as the sub-district of 6 signs is measured and to upper strata feedback measurement result, perhaps UE measures the sub-district of 8 signs in greater than 200ms such as 300ms and to upper strata feedback measurement result UE in 200ms.When if the Pcell signal quality is lower than s-measure, the demand of different-frequency measure task is at most to 3 frequencies in 480*3ms in the UE executive system, the sub-district of minimum 4 signs of each frequency is measured and is fed back measurement result to the upper strata, when the Pcell signal quality is higher than s-measure so, in the UE executive system demand of different-frequency measure task can relax for, UE in 480*2ms at most to less than 3 as 2 frequencies, each frequency is minimum less than 4 as the sub-district of 3 signs is measured and to upper strata feedback measurement result, perhaps at most to 3 frequencies, measure and feed back measurement result to the upper strata by the sub-district of minimum 4 signs of each frequency in greater than 480*3ms such as 560*3ms for UE.Longer measurement form such as the cycle at interval in the cycle that perhaps increases is 160ms, gap length does not become 6ms, form at interval can be measured for UE disposes two covers in the base station, when the Pcell signal quality is lower than s-measure, the employing cycle, the measurement of measurement task in the system was carried out in short measurement at interval, when the Pcell signal quality was higher than s-measure, the employing cycle, the measurement of measurement task in the system was carried out in long measurement at interval.
The 5th kind, the base station will need the measurement task measured immediately, adopt the measuring object tabulation or measure the identification list mode to be notified to user equipment (UE), and the measuring object in tabulation or measure the corresponding measurement task of sign needs UE to carry out measurement immediately.Can send described measuring object tabulation or measure identification list to user equipment (UE) by the radio resource control RRC signaling, notifying UE to need to carry out the measurement task of measuring immediately has which.
Application example one: the component carrier information notice UE of carrier aggregation directly will be supported in the base station
On the component carrier CC1 in the resident carrier aggregation of the UE sub-district 1, having comprised the component carrier that can carry out polymerization in the carrier aggregation sub-district 1 in the system message of the Serving cell on the CC1 is the information of CC1/CC2/CC3, and the CC ID that can also comprise the CC1/CC2/CC3 correspondence in this system message is respectively 1/2/3.UE is known by the system message of this sub-district, the component carrier that can carry out polymerization in the carrier aggregation sub-district 1 is CC1/CC2/CC3, according to current agreement regulation, carrier frequency for measuring object is the measurement task of CC1/CC2/CC3, not controlled by s-measure, after UE receives above-mentioned relevant measurement task, carry out the measurement that these measure task at once.
Current also have CC4 (LTE system), CC5 (UMTS system) with the carrier wave CC1 adjacency.As shown in Figure 1, also be distributed with pico or femto sub-district on the CC3.Because the upper-layer service demand, UE initiates RRC and connects the request of setting up (mainly comprising random access procedure) on CC1, after random access procedure is finished, obtains TA, and CC1 is PCC, and the Serving cell on the CC1 is Pcell, and UE enters connected state afterwards.
Network side is provided with simultaneously and measures startup thresholding s-measure to the measurement configuration that UE issues, and comprises following measurement task:
Measurement task 1: the carrier frequency of measuring object is CC1, and trigger event A2, TTT are 0;
Measurement task 2: the carrier frequency of measuring object is CC1, trigger event A3, and skew is-6db that TTT is 0;
Measurement task 3: the carrier frequency of measuring object is CC2, trigger event A3, and skew is-6db that TTT is 0;
Measurement task 4: the carrier frequency of measuring object is CC3, trigger event A3, and skew is-6db that TTT is 0;
Measurement task 5: the carrier frequency of measuring object is CC4, trigger event A3, and skew is 0, TTT is 0;
Measurement task 6: the carrier frequency of measuring object is CC5, and trigger event B2, TTT are 0.
After UE received above-mentioned measurement task, for measurement task 1, trigger event was A2, and promptly the signal quality of Serving cell is lower than appointed threshold, not controlled by s-measure, and UE is carrying out the measurement of this measurement task always.
For measurement task 2/3/4, the carrier frequency of measuring object is CC1/CC2/CC3, is the component carrier that can carry out polymerization in the current service cell (carrier aggregation Serving cell 1), therefore for these measurement tasks, not controlled by s-measure, UE is carrying out these measurements of measuring task always.As shown in Figure 2, T1 constantly, measurement task 4 reporting measurement reports, the trigger condition that carrier aggregation Serving cell 1 on the CC3 satisfies incident A3 (is higher than the signal quality of Pcell-6db), T3 constantly, the trigger condition that measurement task 3 reporting measurement reports, the carrier aggregation Serving cell 1 on the CC2 satisfy incident A3 (is higher than the signal quality of Pcell-6db).
For measurement task 5/6, determine when start measurement according to the signal quality of current Pcell, promptly when being lower than s-measure, the signal quality of Pcell starts the measurement of measurement task 5/6.Shown in Figure 2, in the T4 moment, UE starts the measurement of measurement task 5/6.
When the T2 moment, UE need increase service bandwidth, and the base station need increase Scell, and according to the current measurement report of receiving, the base station determines to increase CC3 clearly.The component carrier that current UE is used simultaneously is CC1 and CC3.
Among this embodiment, the base station can not be CC1/CC2/CC3 information notice UE by system message with the component carrier that can carry out polymerization in the carrier aggregation sub-district 1 yet, can be when giving UE sending measuring task, utilize the measurement task message to carry component carrier information, with this information notice UE, perhaps directly notify UE, CC ID is that 1/2/3 component carrier is the component carrier that can carry out polymerization.After UE receives, according to current agreement regulation, carrier frequency for measuring object is the measurement task of CC1/CC2/CC3, perhaps the identical measurement task of carrier frequency of the component carrier that the carrier frequency of measuring object and CC ID 1/2/3 are corresponding is not controlled by s-measure, after UE receives above-mentioned relevant measurement task, carry out the measurement that these measure task at once, follow-up implementation is same as described above.
Above-mentioned CC1/CC2/CC3 can be component carrier all or part of that can carry out polymerization, and promptly can to carry out the component carrier of polymerization be CC1/CC2/CC3 in carrier aggregation sub-district 1, and that notice UE also is CC1/CC2/CC3, and that perhaps notify UE is CC1/CC2.
Application example two: in measuring object, increase and carry out the indication information of measuring immediately
In the resident carrier aggregation of the UE sub-district 1 on the CC1.Current also have CC4 (LTE system), CC5 (UMTS system) with the carrier wave CC1 adjacency.As shown in Figure 1, also be distributed with pico or femto sub-district on the CC3.
