Description
Technical field
The present invention relates to technical field of digital mobile communication, relate generally in carrier aggregation measure interval collocation method, subscriber equipment and base station.
Background technology
In cell mobile communication systems, cell reselection and switching are its important functions.In order to realize cell reselection smoothly, subscriber equipment (User Equipment is called for short UE) needs to measure the signal quality of different districts, so that it is resident to select suitable community to carry out.When UE is after certain community and network connect, UE still needs to measure the signal quality of its neighbor cell, to select suitable community to switch, meets mobility requirement.
Terminal is under connected state, the detailed process measured is: Survey control message is sent to UE by network side, wherein, this Survey control message comprises measures mark (Measurement Identity, be called for short MID), measuring object (Measurement Object, be called for short MO), report configuration (Report Configuration, be called for short RC) and other association attributeses of measuring.UE goes to perform measurement according to the measuring object in Survey control message, report configuration, and reports network side according to measurement result generation measurement report.Each measurement task comprises measures mark, measuring object attribute (as the carrier frequency (center frequency point of carrier wave, i.e. ARFCN(Absolute Radio Frequency Channel Number, absolute wireless channel numbering), Neighboring Cell List etc.) and report configuration attribute (as event triggering reports or periodic report, trigger event defines (A1, A2 by trigger condition ...), thresholding, skew etc. that trigger condition is relevant, TTT(Time To Trigger, the triggered time)).Different according to the carrier frequency at measuring object place, be divided into common frequency measurement and different-frequency measure, namely the carrier frequency of measuring object is identical with the carrier frequency at place, Serving cell is then common frequency measurement, the carrier frequency of measuring object is different from the carrier frequency at place, Serving cell is then different-frequency measure, and it is not E-UTRAN(evolved universal terrestrial radio access network that isosystem measurement refers to measuring object) measurement task.For the measurement of common frequency measurement task, UE directly can perform measurement, does not need to measure interval (measurement gap).For the measurement of the measurement task of the different system of alien frequencies, UE needs network side allocating and measuring interval, a period of time of namely specifying, and during this period of time, the measurement performing the different system of alien frequencies is gone in the communication of UE brief interruption and Serving cell.If need allocating and measuring interval, measurement interval is configured to UE by RRC reallocation message by base station.The carrier frequency at place, Serving cell refers to the center frequency point that communication is carried out in UE and this Serving cell.
LTE(long evolving system) in, UE can only carry out communication by a community and base station under connected state, when UE performs the measurement of alien frequencies isosystem measurement task, base station determines to UE allocating and measuring interval, UE is within the time that this measurement interval is specified, perform alien frequencies isosystem measurement, UE can not be dispatched in base station.
For providing higher data rate to mobile subscriber, advanced long-term evolution system (Long Term Evolution Advance, be called for short LTE-A) propose carrier aggregation technology (Carrier Aggregation, be called for short CA), its objective is that the UE for having respective capabilities provides larger broadband, improving the peak rate of UE.In LTE, the maximum downstream transmission bandwidth of system support is 20MHz, and carrier aggregation the component carrier of two or more (Component Carriers is called for short CC) is aggregating support be greater than 20MHz, the maximum transmission bandwidth being no more than 100MHz.There is the LTE-A UE of carrier aggregation capacity, can simultaneously transceiving data on multiple component carrier, the UE below related to is this type of UE except illustrating.In lte-a system, UE to enter after connected state can simultaneously by multiple component carrier (as CC1, CC2) communicate with source base station, base station can be that UE specifies a principal component carrier wave (Primary Component Carrier by explicit configuration or according to protocol conventions, be called for short PCC), other component carrier is called auxiliary component carrier (Secondary Component Carrier, be called for short SCC), descending at DL() Serving cell on PCC is called main Serving cell (Primary Cell, be called for short Pcell), Serving cell on DL SCC is called auxiliary serving cell (Secondary Cell, be called for short Scell).Whether carrier aggregation is continuous on frequency domain by each component carrier, can divide continuous print carrier aggregation and discrete carrier aggregation.Therefore can carry out communication by multiple community and base station after UE enters connected state in carrier aggregation simultaneously, when UE performs the measurement of alien frequencies isosystem measurement task, base station determines to UE allocating and measuring interval, UE is within the time that this measurement interval is specified, perform alien frequencies isosystem measurement, UE can not be dispatched in base station.
In order to support carrier aggregation, the corresponding requirement of radio-frequency structure demand fulfillment of UE.In LTE-A, the receiver of UE has two types, and one only has a receiver, and the bandwidth of support, more than 20MHz, only supports continuous print carrier aggregation in same frequency band.Another has multiple receiver, and the bandwidth of each receiver support is less than or equal to 20MHz, supports continuous print carrier aggregation and the discrete carrier aggregation of different frequency bands in same frequency band.Structure due to UE receiver is inner realization, according to current common recognition, the algorithm of base station needs to shield these internal structures, therefore in some cases, base station cannot determine that UE performs alien frequencies isosystem measurement the need of allocating and measuring interval, as mentioned in Fig. 1, UE has two independently receivers, support the bandwidth of 20M respectively, receiver 1 support performance is at frequency band 1, 2, on 3, receiver 2 support performance is at frequency band 1, 4, on 5, if base station only configures the one-component carrier wave on frequency band 1 to UE, so UE can make receiver 1 or receiver 2 enter operating state, if adopt receiver 1, so the UE different-frequency measure performed on frequency band 2 or 3 just needs to measure interval, but the different-frequency measure performed on frequency band 4 or 5 does not just need to measure interval.And in carrier aggregation technology, to how carrying out measuring interval configuration, clear and definite definition is not proposed at present.

Shown in Fig. 4, the flow process of the present embodiment comprises step below:
Step 101, UE are configured with the cell1 of center frequency point on F1 and the cell2 of center frequency point on F2 in communication process, F1 and F2 belongs to frequency band 1, UE carries out Resourse Distribute according to the situation of self, the service condition of result current UE receiver is: receiver 1 is operated on cell1, receiver 2 is operated on cell2, is configured with following measurement task simultaneously:
MID=1，MO=F1，RC=A3；
MID=2，MO=F2，RC=A6；
MID=3，MO=F3，RC=A3；
MID=4，MO=F4，RC=B2；
Wherein F3 belongs to frequency band 4, F4 and belongs to frequency band 5.
Step 102, base station find that the measurement task of configuration comprises different-frequency measure and isosystem measurement (MID=3/4), then determine to UE allocating and measuring interval, by RRC(Radio Resource Control, radio resource control) measurement interval configuration information issued UE by reallocation message.
Step 103, after UE receives the RRC reallocation message of carrying and measuring interval configuration information, according to the configuring condition (namely needing to measure the adjacent area on F3 and F4) of the task of measurement, resource allocation conditions (to be namely configured with on F1 and Serving cell) on F2, the ability (i.e. the service condition of the receiver of self and the frequency band of support) of UE, as two receivers all work on band 1, but owing to being independent receiver, and receiver 2 can support frequency band 4 and 5, therefore determine that measurement interval information is configured in the allocating and measuring interval supplementary on cell2, and measuring interval by RRC dedicated signaling informing base station only to need to be applied in cell2 on (namely within the time that measurement interval is specified, UE brief interruption performs relevant measurement to the communication of cell2, other Serving cells proceed normal communication as cell1 is then unaffected), RRC dedicated signaling can complete message for RRC reprovision.
Step 104, UE are within the time that measurement interval is specified, and the communication of brief interruption and cell2, performs the measurement that measurement task MID is 3 and 4.
Step 105, base station receive the RRC dedicated signaling that UE sends, and after RRC reprovision completes message, know that UE measures interval configuration from Row sum-equal matrix, namely measure interval to be only applied on cell2, measuring in the time of specifying of interval, can normal consistency cell1, can not cell2 be dispatched.
It is as follows that step 106, base station determine to configure a measurement task by RRC reallocation message again, and wherein F5 belongs to frequency band 2, do not revise the configuration of measuring interval simultaneously:
MID=5，MO=F5，RC=A3。
Step 107, after UE receives the RRC reallocation message configuring above-mentioned measurement task, configuring condition according to the task of measurement (namely needs to measure F3, F4, adjacent area on F5), resource allocation conditions (to be namely configured with on F1 and Serving cell) on F2, the ability (i.e. the service condition of own receiver and the frequency band of support) of UE, the measurement of frequency band 2 supported by receiver 1, but when pre-test interval is only applied to cell2, namely on receiver 2, therefore at RRC dedicated signaling, as RRC reprovision completes in message, reply the allocating and measuring interval supplementary measured interval and need to be applied on cell1 and cell2, UE is applied on cell1 and cell2 according to allocating and measuring interval supplementary from being about to measure interval, namely measuring interval is applied on cell1 and cell2,
Step 108, UE measuring in the time of specifying of interval, need the communication of brief interruption and cell1 and cell2 perform MID=3,4 and 5 measurement.
Step 109, base station receive the RRC dedicated signaling that UE sends, after RRC reprovision completes message, know that UE measures interval configuration from Row sum-equal matrix, namely measure interval and be applied on cell1 and cell2, within the time that measurement interval is specified, can not normal consistency cell1 and cell2.
Embodiment two:
UE is in connected state in EUTRAN system, and UE has three independent receivers, supports the bandwidth of 20M respectively, as shown in Figure 5.
Shown in Fig. 6, the flow process of the present embodiment comprises step below:
Step 201, UE are configured with the cell1 of center frequency point on F1 and the cell2 of center frequency point on F2 in communication process, F1 and F2 belongs to frequency band 1, UE carries out Resourse Distribute according to the situation of self, the service condition of result current UE receiver is: receiver 1 is operated on cell1, receiver 2 is operated on cell2, be configured with following measurement task, wherein F3 belongs to frequency band 5 simultaneously:
MID=1，MO=F1，RC=A3
MID=2，MO=F2，RC=A6
MID=3，MO=F3，RC=A3
Step 202, base station find that the measurement task of configuration comprises different-frequency measure (MID=3), then determine, to UE allocating and measuring interval, by RRC reallocation message, measurement interval configuration information to be issued UE.
Step 203, after UE receives the RRC reallocation message at allocating and measuring interval, according to the configuring condition (needing to measure the adjacent area on F3) of the task of measurement, resource allocation conditions (to be namely configured with on F1 and Serving cell) on F2, the ability (service condition of the receiver of self and the frequency band of support) of UE, as receiver 1 and receiver 2 all work on band 1, but receiver 3 not yet enters operating state, and receiver 3 can support frequency band 5, therefore receiver can complete the measurement on frequency band 5, therefore by RRC dedicated signaling, as RRC reprovision completes in message, the allocating and measuring interval supplementary informing base station of the measurement performing measurement task MID=3 is removed at the allocating and measuring interval that do not need determined, UE does not perform the configuration of measuring interval simultaneously, namely UE side does not have allocating and measuring interval.
Now UE also can perform the configuration of measuring interval according to the configuration of base station, and the cancellation waiting base station follow-up cancels the configuration of measuring interval after measuring the RRC reallocation message at interval again.
Step 204, UE do not need the communication of brief interruption and cell1 and cell2, are performed the measurement of measurement task MID=3 by receiver 3.
Step 205, base station receive the RRC dedicated signaling that UE sends, and after RRC reprovision completes message, or UE does not accept the configuration of measuring interval, does not send and cancels message to UE, according to normal consistency cell1 and cell2.Now also can notify that UE cancels and measure interval, as sent RRC reallocation message to UE.
It is as follows that step 206, subsequent base stations determine to configure a measurement task by RRC reallocation message again, and wherein F4 belongs to frequency band 6, does not have allocating and measuring interval simultaneously:
MID=4，MO=F4，RC=A3。
Step 207, after UE receives the RRC reallocation message configuring above-mentioned measurement task, configuring condition according to the task of measurement (namely needs to measure F3, adjacent area on F4), resource allocation conditions (to be namely configured with on F1 and Serving cell) on F2, the ability (service condition of own receiver and the frequency band of support) of UE, receiver 3 is idle and support the measurement of frequency band 6, therefore determine to perform according to the configuration of base station completely, by RRC dedicated signaling, as RRC reprovision completes message, reply the allocating and measuring interval supplementary performed according to the configuration of base station completely, or do not reply any indication information.
Step 208, base station receive the RRC dedicated signaling that UE sends, and after RRC reprovision completes message, know that UE does not need to measure interval and performs relevant measurement, then according to normal consistency cell1 and cell2.
It is as follows that step 209, subsequent base stations determine again to configure a measurement task by RRC reallocation message again, and wherein F5 belongs to frequency band 2, does not have allocating and measuring interval simultaneously:
MID=5，MO=F5，RC=A3。
Step 210, after UE receives the RRC reallocation message of the above-mentioned measurement task of this configuration, configuring condition according to the task of measurement (namely needs to measure F3, F4, adjacent area on F5), resource allocation conditions (to be namely configured with on F1 and Serving cell) on F2, the ability (i.e. the service condition of own receiver and the frequency band of support) of UE, the idle measurement still not supporting frequency band 2 of receiver 3, therefore by RRC dedicated signaling as RRC reprovision completes message, reply and need to measure the allocating and measuring interval supplementary that interval could perform different-frequency measure, further can comprise the information measured interval and need to be applied on cell1.
Step 211, base station receive the RRC dedicated signaling that UE sends, and after RRC reprovision completes message, base station determines to the measurement interval configuration information of UE configuration according to the allocating and measuring interval supplementary that UE feed back, as measurement interval being applied in the information on cell1.
After step 212, UE receive configuration, within measurement interval instruction time, the measurement performing MID=5 is gone in the communication of brief interruption and cell1, and cell1, then according to normal consistency cell2, is not dispatched in base station.
Embodiment three:
UE is in connected state in EUTRAN system, and UE has an independent receiver, supports the bandwidth of 40M, as shown in Figure 7.
Shown in Fig. 8, the flow process of the present embodiment comprises step below:
Step 301, UE are configured with the cell1 of center frequency point on F1 and the cell2 of center frequency point on F2 in communication process, all belong to frequency band 1 and be continuous print, UE carries out Resourse Distribute according to the situation of self, the service condition of result current UE receiver is: receiver 1 is operated on cell1 and cell2 simultaneously, is configured with following measurement task simultaneously:
MID=1，MO=F1，RC=A3；
MID=2，MO=F2，RC=A6；
MID=3，MO=F3，RC=A3；
MID=4，MO=F4，RC=B2。
Wherein, F3 ownership frequency band 2, F4 belongs to frequency band 3.
Step 302, base station find that the measurement task of configuration comprises different-frequency measure and isosystem measurement (MID=3/4), then determine, to UE allocating and measuring interval, by RRC reallocation message, measurement interval configuration information to be issued UE.
After step 303, UE receive the RRC reallocation message at allocating and measuring interval, according to the configuring condition (namely needing to measure the adjacent area on F3/F4) of the task of measurement, resource allocation conditions (to be namely configured with on F1 and Serving cell) on F2, the ability (i.e. the receiver service condition of self and the frequency band of support) of UE, as unique receiver has been operated on F1 and F2, and frequency band 2 and 3 supported by receiver, therefore, determine at RRC dedicated signaling as RRC reprovision completes in message, do not carry any indication information, or the measurement interval of base station configuration is adopted in instruction completely.
Step 304, UE need the communication of brief interruption and cell1 and cell2, could perform the measurement of measurement task MID=3 and 4.
Step 305, base station receive RRC dedicated signaling that UE sends as after RRC reprovision completes message, within the measurement interval fixed time, do not dispatch UE, namely do not dispatch cell1 and cell2.
Embodiment four:
UE is in connected state in EUTRAN system, and UE has two independent receivers, supports the bandwidth of 20M respectively, as shown in Figure 3.
Shown in Fig. 9, the flow process of the present embodiment comprises step below:
Step 401, UE are configured with the cell1 of center frequency point on F1 and the cell2 of center frequency point on F2 in communication process, F1 and F2 belongs to frequency band 1, UE carries out Resourse Distribute according to the situation of self, the service condition of result current UE receiver is: receiver 1 is operated on cell1, receiver 2 is operated on cell2, is configured with following measurement task simultaneously:
MID=1，MO=F1，RC=A3；
MID=2，MO=F2，RC=A6；
MID=3，MO=F3，RC=A3。
Wherein, F3 belongs to frequency band 4.
Step 402, base station find that the measurement task of configuration comprises different-frequency measure (MID=3), UE is then asked to report the supplementary at allocating and measuring interval, by RRC dedicated signaling as RRC reallocation message issues UE, described request can be implicit expression, as terminal decides the supplementary measuring interval the need of feedback configuration in its sole discretion according to the content that base station configures, or explicit, as base station explicit notification UE needs feedback configuration to measure the supplementary at interval.
Step 403, after UE receives the request of base station, according to the configuring condition (namely needing to measure the adjacent area on F3) of the task of measurement, resource allocation conditions (to be namely configured with on F1 and Serving cell) on F2, the ability (i.e. the receiver service condition of self and the frequency band of support) of UE: as two receivers all work on band 1, and frequency band 4 supported by receiver 2, therefore determine that measurement interval only needs the allocating and measuring interval supplementary be applied on cell2 Serving cell, by RRC dedicated signaling as RRC reprovision completes message informing base station, measure interval only to need to be applied in cell2 Serving cell, if UE has three independently receivers, or there is independent measurement module to support the measurement of frequency band 4, then can allocating and measuring interval not be needed to go to perform the measurement of measurement task MID=3 by informing base station.
Step 404, base station need the measurement on UE execution F3, according to the allocating and measuring interval supplementary that above-mentioned UE reports, determine the configuration of measuring interval.
If UE reports do not need allocating and measuring interval, then subsequent step is without the need to performing, and UE does not need to measure the measurement on interval execution F3, and base station also can normal consistency cell1 and cell2.
After step 405, UE receive the RRC reallocation message at allocating and measuring interval, base station, measure interval according to the instruction of base station and be only applied on cell2, perform the measurement of measurement task MID=3 in the communication of measuring brief interruption and cell2 in interval.
Step 406, base station receive after RRC reprovision that UE sends completes message, measuring in the time of specifying of interval, according to normal consistency cell1, do not dispatch cell2.
Embodiment five:
UE is in connected state in EUTRAN system, and UE has three independent receivers, supports the bandwidth of 20M respectively, as shown in Figure 5.
Shown in Figure 10, the flow process of the present embodiment comprises step below:
Step 501, UE are configured with the cell1 of center frequency point on F1 and the cell2 of center frequency point on F2 in communication process, F1 and F2 belongs to frequency band 1, UE carries out Resourse Distribute according to the situation of self, the service condition of result current UE receiver is: receiver 1 is operated on cell1, receiver 2 is operated on cell2, be configured with following measurement task, wherein F3 belongs to frequency band 5, F4 and belongs to frequency band 6 simultaneously:
MID=1，MO=F1，RC=A3
MID=2，MO=F2，RC=A3
MID=3，MO=F3，RC=A3
MID=4，MO=F4，RC=A3
Step 502, base station find that the measurement task of configuration comprises different-frequency measure (MID=3/4), then determine, to UE allocating and measuring interval, by RRC reallocation message, measurement interval configuration information to be issued UE.
Step 503, after UE receives the RRC reallocation message at allocating and measuring interval, according to the configuring condition (namely needing to measure the adjacent area on F3 and 4) of the task of measurement, resource allocation conditions (to be namely configured with on F1 and Serving cell) on F2, the capabilities might (service condition of the receiver of UE self and the frequency band of support) of UE, as receiver 1 and receiver 2 all work on band 1, but receiver 3 not yet enters operating state, and receiver 3 can support frequency band 5 and frequency band 6, therefore receiver can complete the measurement on frequency band 5/6, therefore determine not need allocating and measuring interval, by RRC dedicated signaling, as RRC reprovision completes in message, informing base station, allocating and measuring interval is not needed to go to perform the measurement of measurement task MID=3/4, UE does not perform the configuration of measuring interval simultaneously, namely UE side does not have allocating and measuring interval.
Step 504, UE do not need the communication of brief interruption and cell1 and cell2, are performed the measurement of measurement task MID=3/4 by receiver 3.
Step 505, base station receive the RRC dedicated signaling that UE sends, and after RRC reprovision completes message, know that UE does not accept to measure the configuration at interval, do not send and cancel message to UE, according to normal consistency cell1 and cell2.
Step 506, subsequent base stations determine to configure the cell3 of center frequency point on F4 by RRC reallocation message again, and wherein F4 belongs to frequency band 6, simultaneously not newly-increased or amendment measurement task.
Step 507, after UE receives the RRC reallocation message of the above-mentioned Serving cell of this configuration, receiver 3 is operated on cell3, according to the configuring condition (namely needing to measure the adjacent area on F3) of the task of measurement, resource allocation conditions (is namely configured with on F1 and F2, Serving cell on F4), the ability (i.e. the service condition of own receiver and the frequency band of support) of UE, although the measurement of frequency band 5 supported by this receiver, but receiver 3 is not idle, therefore need to measure interval, and measure interval can only be applied on cell3, by RRC dedicated signaling as RRC reprovision completes message, reply needs to measure interval could perform different-frequency measure, further can comprise measurement interval to need to be applied on cell3.
Step 508, base station receive the RRC dedicated signaling that UE sends, after RRC reprovision completes message, know that UE needs to measure interval and performs relevant measurement, can also notify that this measurement interval is applied on cell3, then measure interval by RRC reprovision command configuration, this measurement interval is applied on cell3 further.
After step 509, UE receive configuration, within measurement interval instruction time, the measurement performing MID=3 is gone in the communication of brief interruption and cell3, and cell3 then according to normal consistency cell1 and cell2, is not dispatched in base station.
Step 510, subsequent base stations determine again to delete cell2 by RRC reallocation message again:
Step 511, after UE receives the RRC reallocation message of deleting cell2, receiver 2 enters the free time, according to the configuring condition (namely needing to measure the adjacent area on F2 and F3) of the task of measurement, resource allocation conditions (to be namely configured with on F1 and Serving cell) on F4, the ability (i.e. the service condition of own receiver and the frequency band of support) of UE, receiver 2 free time can perform the measurement on frequency band 1, but do not support the measurement of frequency band 5, therefore still need to measure the measurement that interval performs MID=2/3, this measurement interval can only be applied on cell3 further, current base station is allocating and measuring interval, further measurement interval is also applied on cell3, therefore, by RRC dedicated signaling, as RRC reprovision completes message, reply and do not need to modify to the configuration of current measurement interval, or reply and need measurement interval to perform different-frequency measure, further can comprise measurement interval to need to be applied on cell3, within measurement interval instruction time, the measurement performing MID=3 is gone in the communication of brief interruption and cell3, the measurement of MID=2 is performed with receiver 2.
Step 512, base station receive the RRC dedicated signaling that UE sends, and after RRC reprovision completes message, base station is known not to be needed to revise the configuration information measuring interval, and within measurement interval instruction time, cell3, then according to normal consistency cell1, is not dispatched in base station.
The operation of above-mentioned steps 506 and 511 can in the order of same RRC reprovision, namely cell2 is replaced with cell3, after UE receives, receiver 2 enters the free time, receiver 3 is operated in cell3, according to the configuring condition (namely needing to measure the adjacent area on F2/F3) of the task of measurement, resource allocation conditions (to be namely configured with on F1 and Serving cell) on F4, the ability (i.e. the service condition of own receiver and the frequency band of support) of UE, receiver 2 free time can perform the measurement on frequency band 1, but do not support the measurement of frequency band 5, therefore still need to measure the measurement that interval performs MID=2/3, this measurement interval can only be applied on cell3 further, current base does not have allocating and measuring interval, therefore by RRC dedicated signaling as RRC reprovision completes message, reply needs to measure interval could perform different-frequency measure, further can comprise measurement interval to need to be applied on cell3, within measurement interval instruction time, the measurement performing MID=3 is gone in the communication of brief interruption and cell3, the measurement of MID=2 is performed with receiver 2.
