Description
Technical field
The present invention relates to the communications field, in particular to the cell group method of adjustment in a kind of multicarrier system and
System.
Background technology
Advanced long-term evolution system (Long Term Evolution Advance, referred to as LTE-Advanced) is
Third generation partnership project (the 3rd Generation Partner Project, referred to as 3GPP) tissue is in order to meet state
Border telecommunication union (International Telecommunication Union, referred to as ITU), senior international mobile communication
The requirement of (International Mobile Telecommunication-Advanced, referred to as IMT-Advanced) and
The standard of release.LTE-Advanced systems are in long evolving system (Long Term Evolution, referred to as LTE) base
An evolution version on plinth, it introduces many new techniques to meet the primary demand of IMT-Advanced, wherein most important
A technology be exactly carrier aggregation.
Due to the property in short supply of current radio spectrum resources, the frequency spectrum resource that each mobile operator in the world possesses often compares zero
Dissipate, and IMT-Advanced requires that the index of peak rate is higher and (100Mbps supported under high mobility, is supported under Hypomobility
1Gbps), IMT-Advanced requirements cannot be met with the bandwidth of current LTE standard maximum 20MHz, so needing to expand
It is charged to more high bandwidth, such as 40MHz, 60MHz, even more high.It is that frequency domain is entered to improve one of method of bandwidth and peak rate
Row expands, for example, several LTE frequency bands based on 20MHz are carried out bandwidth expansion by way of " carrier aggregation ", here it is carrying
The essence of ripple polymerization technique.Therefore, LTE-Advanced systems fall within multicarrier system.
Apply in the LTE-Advanced systems of carrier aggregation technology, the carrier wave for participating in polymerization is referred to as component carrier
(Component Carrier), user equipment (UserEquipment, referred to as UE) can simultaneously on multiple component carriers
Transmitting-receiving transmission is carried out with eNB.Component carrier can use LTE defined frequency ranges, it is also possible to use as LTE-Advanced
Special newly-increased frequency range.It is nervous based on current frequency spectrum resource, it is impossible to always to have continuous component carrier on frequency domain distribute to
Operator uses, therefore component carrier can be continuous, or discontinuous on frequency band.Introduce in carrier aggregation
Main plot and the concept of secondary cell, main plot refer to that UE initiates RRC (Radio Resource Control, wireless heterogeneous networks) even
Connect foundation or RRC connection reconstructions or the cell of main plot is designated as in handoff procedure；Secondary cell refers to and is different from main plot
Frequency, and configure after UE enters RRC connection status, for providing extra Radio Resource.In carrier aggregation system, service
Cell includes main serving cell and auxiliary serving cell.
After introducing carrier aggregation technology, UE can be simultaneously in multiple Serving cells in RRC connected states (RRC_CONNECTED)
On carry out transmitting-receiving transmission, but for the UE of Idle state (RRC_IDLE), as LTE, be only capable of it is resident on one cell, UE
After being successfully accessed in the cell, i.e. after UE sets up RRC connections in the cell, according to service needed, base station can be by special
It is the newly-increased cell of UE distribution with RRC signaling, distributes base station and UE after these newly-increased cells not enterprising in the newly-increased cell immediately
Row data transmit-receive, i.e. base station do not send business datum to UE in the newly-increased cell, and UE preserves the configuration information in the cell,
Also business datum is not sent to base station in the cell, wait the further action of base station.Subsequent base stations can be according to business
Need to activate the cell, after the cell is activated, base station and UE could carry out data transmit-receive in the cell.
In LTE system, in order to realize and keep the uplink synchronous between user equipment and base station, base station according to base station with
Propagation delay time between each user equipment sends Timing Advance (Timing Advance, referred to as TA) to each user equipment,
User equipment shifts to an earlier date or postpones according to the Timing Advance that base station sends the opportunity of respective uplink, so as to make up in user eventually
Hold to the propagation delay time of base station so that the upward signal of different user devices all reaches base station within the reception window of base station.
Do not dispose in the cell configured if certain user equipment (UE) Remote Radio Unit (Remote radio header,
RRH) or power amplifier (repeater), then the corresponding main plots of the UE and secondary cell use identical TA；If
RRH or Repeater is deployed with the cell that certain user equipment (UE) is configured, as RRH or Repeater can cause UE to exist
Propagation delay when upward signal is sent on different districts is different, if UE is in the corresponding areas of coverage of RRH or repeater
And carry out carrier aggregation, then now the corresponding cells of RRH or repeater are needed using different TA from the cell on eNB.
Carrier aggregation specifies that a UE could support up 5 carrier waves and is polymerized at present, then this is accomplished by the concept for introducing packet, even if
Little with identical TA divides into one group.
In LTE system, in the case of multi-carrier polymerizing, with the movement and the change of channel circumstance of UE, may cause to make
Changed with the cell of identical TA, so as to the packet situation for causing cell changes.
There is difference TA, due to the mobility of UE, some Serving cells for the Serving cell in correlation technique because of terminal
The possible occurrence dynamics changes of the TA of needs, the TA received in causing some packets can not meet some services in the packet
The timing adjustment demand of cell, can cause upward signal to pass if continuation carries out time adjustment using original TA in these cells
Input mistake by mistake.Therefore the dynamic adjustment being grouped to this kind of Serving cell is needed, is adjusted in suitable packet.For presence not
Under with many TA systems of the multicarrier of TA, the dynamic adjustment how to be grouped to Serving cell not yet proposes effectively to solve at present

The thresholding of group adjustment, if result meets the adjustment thresholding of cell group, UE sends upstream message to base station, indicates base station
A little cells reach adjustment thresholding or indicate that base station needs to enter which cell Mobile state adjustment.When base station continuously receives the N of UE
The dynamic adjustment being grouped after secondary message.
Or UE voluntarily records the number of times for meeting cell group adjustment, if continuous n times meet adjustment thresholding, UE is to base
Transmission measurement of standing reports instruction, indicates that base station enters Mobile state adjustment to which cell.N can be carried out to UE from base station by signaling
Configuration, or the value of a determination.
Method two：Base station reports cycle or the reported event of downstream signal reaching time-difference, UE by signaling to UE configurations
After every time calculating time difference it is poor with accumulated time carry out it is average, when report cycle is then or when reported event meets condition, Xiang Ji
Transmission of standing reports instruction message, and base station decides whether the dynamic adjustment being grouped according to reporting value to be judged.
The schematic diagram of the covering of carrier aggregation shown in Figure 2, below with mode of frequency division duplexing (Frequency
Division Duplex, referred to as FDD) as a example by being described.As shown in Fig. 2 Serving cell 1 (descending frequency f1, it is up
Frequency f1 '), referred to as CC1 (DL f1, UL f1 ')；Serving cell 2 (descending frequency f2, up frequency f2 '), referred to as CC2
(DL f2, UL f2 ')；Serving cell 3 (descending frequency f3, up frequency f3 ') can carry out carrier aggregation.Serving cell CC3
Covering be divided into two parts, a part is the Serving cell coverage on base station, and a part is repeater coverages.
User equipment (UE) resides on CC1 and initiates on CC1 RRC connection procedures, and CC1 is the main serving cell of UE.
The initial packet mode of carrier wave and the subsequent dynamic adjustment mode of packet are determined in the carrier aggregation system of many TA.
Based on this, the present embodiment has been changed to the whole description agreement of multicarrier system, i.e., it is right that clearly many TA multicarrier systems need
Cell is grouped；Change is produced to the RRC agreements of UE simultaneously, i.e., adds new in original signaling during initial packet
Configuration parameter, the dynamic adjustment for adding new message between UE and base station for base station to packet.
The dynamic adjusting method of above-mentioned packet and packet is described below by specific example：
Example 1
Referring to Fig. 3, the cell group method of adjustment in the multicarrier system of this example is comprised the following steps：
Step 301：UE initiates RRC connections on CC1, and base station configures CC2 and CC3 to UE in RRC connection reallocation messages
Information.Now there is repeater overlay areas in the area of coverage of CC3；Base station configuration measurement in RRC connection reallocation messages
Information.CC1, CC2 and CC3 are configured to measurement object by base station, and UE is for CC1, CC2 and CC3 measurement downstream signal time of advent；
The information that UE is reported is configured in measurement configuration, that is, the thresholding for triggering measurement report is 512Ts, when time difference is less than 512Ts, UE
Measure and report；The reporting schemes of UE are configured in measurement configuration, i.e. event triggering is reported, when UE detects the upper tape of satisfaction
The backward base station of part is reported, and factor N that reports of measurement can be carried during configuration, and the value of such as N is set to 10.
Step 302：Activation CC2 and CC3, UE when UE is in RRC connection status are initiated on CC2 and CC3 respectively for base station
Uplink synchronous process, after the completion of the uplink synchronous of CC2 and CC3, CC2 and CC3 respectively enter synchronous regime.CC2 and CC3 are each
Safeguard TA；
Step 303：In the areas of coverage of the stage UE of CC3 activation in cell on base station.It is same on UE detection CC3 and CC1
Downstream signal time of advent that subframe sends, judged according to time difference information, now CC3 and CC1 downstream signal time differences
Less than 512Ts.When continuous 10 detections of UE find that downstream signal reaching time-difference is less than 512Ts, UE sends measurement report to base station
Message is accused, indicates that CC3 is less than 512Ts with CC1 downstream signals time difference.What on UE detection CC2 and CC1, same subframe sent is descending
Time of arrival (toa), is judged according to time difference information, and now CC2 is less than 512Ts with CC1 downstream signals time difference.Work as UE
Continuous 10 detections find that downstream signal reaching time-difference is less than 512Ts, and UE sends measurement report message to base station, indicates CC2
512Ts is less than with CC1 downstream signals time difference.
Step 304：Base station receives the measurement report that UE is reported, and CC2 and CC1, CC3 and CC1 downstream signal time differences are little
In 512Ts, base station sends RRC connection reallocation messages and configures in a group CC1, CC2 and CC3, is set to group 1.May be used also base station
So that the condition that UE is reported is reconfigured in measurement configuration, i.e. downgoing time difference is more than 512Ts, and UE is measured and reported；
Step 305：UE receive and using base station send RRC connection reallocation message in be grouped adjustment information.Group 1 is carried out
Safeguard.
Step 306：UE continues executing with CC2 and CC1, the measurement of CC3 and CC1 downgoing times difference, finds CC2 and CC1, CC3
It is poor with the downgoing time of CC1 to be both less than 512Ts, not reporting measurement reports always.
Step 307：After a period of time, UE moves to the overlay area of repeater in CC3.UE continues detection CC3 and CC1
Upper same subframe sends downstream signal time of advent, now CC3 be more than 512Ts with CC1 downstream signals time difference.When UE it is continuous
10 detections find downstream signal reaching time-difference more than after 512Ts, and UE sends measurement report message to base station, indicates base station
CC3 is more than 512Ts with CC1 downstream signals time difference.UE measurements find that the downstream signal time difference of CC2 and CC1 is less than always
512Ts, UE do not send measurement report to base station.
Step 308：Base station receives the measurement report message that UE is reported, and CC3 is grouped by decision again.Base station is sent to UE
RRC connects reallocation message, and CC3 is removed from group 1, and CC3 is configured in group 2.Base station can with measurement configuration in again
The information that configuration UE is reported, that is, report the downgoing time difference that thresholding is CC3 and CC1 less than 512Ts, and UE is measured and reported；
Step 309：UE receive and using base station send RRC connection reallocation message in be grouped adjustment information.Respectively to group 1
Safeguarded with group 2.
Step 310：UE continues executing with CC2 and CC1, the measurement of CC3 and CC1 downgoing times difference, finds under CC3 and CC1
Row time difference is always greater than the downstream signal time difference of 512Ts, CC2 and CC1 always less than 512Ts, then not reporting measurement
Report.
Example 2
Referring to Fig. 4, the cell group method of adjustment in the multicarrier system of this example is comprised the following steps：
Step 401：UE initiates RRC connections on CC1, and base station configures CC2 and CC3 to UE in RRC connection reallocation messages
Information and grouping information.Now due to there is repeater overlay areas, therefore base during initial packet in the area of coverage of CC3
Stand and CC1 and CC2 is configured in a group, be set to group 1；CC3 is configured in another group, group 2 is set to；Base station connects in RRC
Metrical information is configured in connecing reallocation message.CC1 and CC3 are configured to measurement object by base station, and it is descending that UE is directed to CC1 and CC3 measurements
Time of arrival (toa)；The information that UE is reported is configured in measurement configuration, that is, needs the cell for carrying out being grouped adjustment；In measurement configuration
The triggering of the reporting schemes of middle configuration UE, i.e. event is reported, and UE detects that the downstream signal time difference of CC1 and CC3 is less than 512Ts
Afterwards, the cell ID for needing adjustment is reported to base station；
Step 402：CC2 and CC3, after CC3 completes uplink synchronous, UE are activated when UE is in RRC connection status in base station
Can be in the transmitting-receiving of the enterprising row data of CC3.Group 1 and group 2 safeguard the TA of each group respectively；
Step 403：In the areas of coverage of the stage UE of CC3 just activation in repeater on CC3.On UE detection CC3 and CC1
Same subframe sends downstream signal time of advent, now CC3 be more than 512Ts with CC1 downstream signals time difference, UE thinks packet
It is not required to be adjusted, UE not reporting measurement reports.
Step 404：After a period of time, UE moves to the macrocell coverage area of CC3 from the repeater overlay areas of CC3
Domain.UE detects that same subframe sends on CC3 and CC1 again downstream signal time of advent, when now CC3 is with CC1 downstream signals
Between difference less than 512Ts, UE sends measurement report message to base station, indicates that base station CC3 needs to carry out packet adjustment.
Step 405：After base station receives the packet adjustment instruction message of UE, the message bar number is counted.
