Description
Technical field
The present invention relates to the communications fields, in particular to differentiation group management method small in multi-carrier communications systems and are
System.
Background technique
Draw in advanced long-term evolution system (Long Term Evolution Advance, referred to as LTE-Advanced)
Many new technologies are entered to meet the primary demand of IMT-Advanced, one technology of most important one is exactly carrier wave polymerization.
Due to the property in short supply of current radio spectrum resources, and IMT-Advanced requires the index of peak rate higher (high
100Mbps is supported under mobility, supports 1Gbps under Hypomobility), the bandwidth with current LTE standard maximum 20MHz is can not
Meet IMT-Advanced requirement, so need to extend to more high bandwidth, such as 40MHz, 60MHz, it is even higher.Improve band
Wide and peak rate method first is that expand frequency domain, such as several LTE frequency bands based on 20MHz are passed through " carrier wave
The mode of polymerization " carries out bandwidth expansion, and here it is the essence of carrier aggregation technology.Therefore, LTE-Advanced system also belongs to
Multicarrier system.
In LTE-Advanced system, the carrier wave for participating in polymerization is referred to as component carrier (Component Carrier), uses
Family equipment (User Equipment, referred to as UE) can carry out transmitting-receiving transmission with eNB on multiple component carriers simultaneously.Component
LTE defined frequency range can be used in carrier wave, and the frequency range specially increased newly for LTE-Advanced also can be used.Based on current
Frequency spectrum resource is nervous, it is impossible to always have continuous component carrier on frequency domain that can distribute to operator's use, therefore component carrier
It can be continuously, be also possible to discontinuous on frequency band.Main serving cell and auxiliary serving cell are introduced in carrier wave polymerization
Concept, main serving cell refer to UE initiate RRC connection establish RRC connection reconstruction or in handoff procedure it is designated based on service
The cell of cell；Auxiliary serving cell refers to the frequency point for being different from main serving cell, and configures after UE enters RRC connection status, uses
In the additional radio resource of offer.In carrier aggregation system, serving cell includes main serving cell and auxiliary serving cell.

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 establishes RRC connection in the cell, according to business needs, base station can be by special
It is that UE distributes newly-increased cell with RRC signaling, distributing after these newly-increased cells base station and UE, at this, to increase cell newly not enterprising immediately
Row data transmit-receive, i.e. base station do not increase newly at this to UE transmission business datum in cell, and UE saves the configuration information in the cell,
Also business datum is sent to base station not in the cell, waits the further movement of base station.Subsequent base stations can be according to business
It needs to activate the cell, after which is activated, base station and UE could carry out data transmit-receive in the cell.UE is in each auxiliary clothes
Business one packet data inactivity timer of cell maintenance, the duration of timer are configured by base station.Different, the auxiliary service according to the duration of timer
The deactivation of cell can both be controlled by UE, i.e., timer duration then, or by base station controls, i.e., timer duration is configured to
Infinity, base station send auxiliary serving cell and deactivate MAC control element deactivation auxiliary serving 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 sending time lead (Timing Advance, referred to as TA) between each user equipment gives each user equipment,
The Timing Advance that user equipment is sent according to base station shifts to an earlier date or postpones the opportunity of respective uplink, to make up user terminal
To the propagation delay time of base station, so that the uplink signal of different user devices all reaches base station within the reception window of base station.Such as
Fruit is that the propagation delay time difference of each minizone in the cell of some user equipment (UE) configuration is larger, is not available identical
TA, then just needing to introduce the concept of more TA in carrier aggregation system.The case where according to TA is used, can will use identical TA
UE be placed in same group, thus introduce the concept of grouping.
In carrier aggregation system before, all carrier waves use identical TA, and main serving cell is controlled as TA is received
The cell of element processed, while the also cell as maintenance time adjustment timer, i.e. maintenance TAT.It is grouped when introducing with more TA's
The cell that main serving cell is used only after concept as maintenance TAT is inadequate.Different groupings is according to reception TA in respective group
Time difference need to safeguard different TA timers.It needs to safeguard a TAT in each grouping at this time.Small comprising main service
In the grouping in area, cell of the main serving cell as maintenance TAT can be continued to use.Introducing auxiliary serving cell grouping and every
After a grouping needs to safeguard a TAT, the configuration of cell grouping information is carried out using RRC signaling, requires consideration for how to make at this time
UE knows the information of cell grouping by RRC signaling.Therefore how to make UE by RRC signaling know cell grouping information and
The particular content of grouping information is our urgent problems to be solved at present.
