Description
Technical field
The present invention relates to the communications field, in particular to a kind of re-matching of auxiliary serving cell in multi-carrier communications systems
Method and device.
Background technology
Draw in advanced long-term evolution system (Long Term Evolution Advanced, referred to as LTE-Advanced)
Many new technologies are entered to meet Advanced International Mobile Communications (International Mobile Telecommunications-
Advanced, referred to as IMT-Advanced) primary demand, one technology of most important one is exactly carrier aggregation.
Due to the property in short supply of current radio spectrum resources, and the index higher of IMT-Advanced requirement peak rates is (high
100Mbps is supported under mobility, 1Gbps is supported under Hypomobility), the bandwidth with current LTE standard maximum 20MHz is can not
Meet IMT-Advanced requirements, so need to extend to more high bandwidth, such as 40MHz, 60MHz, it is even higher.Improve band
One of wide and peak rate method is that frequency domain is expanded, 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 systems also belong to
Multicarrier system.
In LTE-Advanced systems, 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 on multiple component carriers with eNB simultaneously.Component
Carrier wave can use LTE defined frequency ranges, can also use the frequency range specially increased newly for LTE-Advanced.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 continuous on frequency band or discontinuous.The concept of main plot and secondary cell is introduced in carrier aggregation, it is main
Cell refers to UE and initiates RRC connections foundation or RRC connection reconstructions or the cell that main plot is designated as in handoff procedure；Secondary cell
Refer to the frequency point for being different from main plot, and be configured after UE enters RRC connection status, for providing additional radio resource.It is carrying
In wave paradigmatic system, serving 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 establishes RRC connections in the cell, according to business needs, base station can be by special
It is the newly-increased cell of UE distribution 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 and send business datum to UE in cell, and UE preserves the configuration information in the cell,
Also business datum is sent to base station not in the cell, waits for the further action 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.
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 to 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, so as 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 larger for the propagation delay time difference of minizone each in the cell of some user device configuration, can not use identical TA, that
Just need to introduce the concept of more TA in carrier aggregation system.According to the situation for using TA, the UE that can will use identical TA
It is placed in same group, thus introduces the concept of grouping.
In carrier aggregation system before, all carrier waves use identical TA, uplink signal of the main plot as UE
Reference carrier during transmission, hereinafter referred to as time reference carrier wave.It is needed after the concept of grouping and more TA is introduced in each grouping
One cell of middle selection is as time reference carrier wave.In the grouping comprising main plot, can be continuing with main plot as when
Between reference carrier；In only the group of multiple secondary cells is included, time reference carrier wave of the secondary cell as the group is selected.Due to
There are the deployment of frequency selective amplifier and radio frequency remote equipment in carrier aggregation system, therefore have during UE is moved
It may change there is a situation where the grouping of auxiliary serving cell, i.e. auxiliary serving cell needs change to another point from current group
Group.When auxiliary serving cell is adjusted and is grouped, base station reconfigures auxiliary serving cell using RRC signaling.When under state of activation
When auxiliary serving cell is relocated to an already existing serving cell grouping, time which should use
Reference carrier (timing reference) and Timing Advance (TA) are all changed, in the new time ginseng of the serving cell
Examine carrier wave and before Timing Advance comes into force, uplink interference can be caused by sending uplink signal or data on the serving cell.
