Description
Technical field
The present invention relates to wireless communication technology field, particularly to a kind of method processing synchronous regime with set
Standby.
Background technology
Along with the deployment of numerous local nodes such as increasing Home eNodeB, Microcell, relaying, traditional
The network architecture based on macro base station will progressively develop into the network architecture that more type of base station coexists, and provides
The network coverage of more levels.In order to improve the correlated performance under the co-existin networks framework of polymorphic type base station, a kind of
The network architecture being realized many cooperation between base stations/polymerizations by non-ideal link is suggested.
Under this architecture, the part carrying RB (Radio of UE (User Equipment, subscriber equipment)
Bearer, radio bearer) manage at MeNB (Master eNB, dominant base) MCell (Master Cell,
Main plot) on, this part RB includes chain of command SRB, and (Signaling Radio Bearer, signaling is wireless
Carrying) and user face DRB (Data Radio Bearer, Data Radio Bearer).And same UE is additionally
Part carrying (including SRB and DRB) manages at SeNB (Secondary eNB, slave base stations)
SCell (Secondary Cell, secondary cell) on.
At a kind of possible multitiered network overlay environment shown in Fig. 1.Under this scene, MeNB and SeNB
Between use nonideal data/signaling interface Xn interface, UE may be simultaneously operated in MeNB and SeNB
Under.When the UE being connected to MeNB enters the coverage of the community corresponding to SeNB, MeNB can
To consider according to signal intensity or load balancing etc., all or part of data/signaling of transfer UE arrives
SeNB is to obtain the service that SeNB provides.Thus realize UE and can use MeNB and SeNB simultaneously
Resource, and between base station be polymerized (inter-eNB polymerization).Under this scene, multiple RB of UE can divide
Not Tong Guo SCG (Secondary Cell Group, secondary cell group) and MCG (Master Cell Group,
Main plot group) carry respectively.The RB being wherein separated to SeNB can include DRB and/or SRB.
UE, doing different-frequency measure when, has and likely can receive on current service frequency normally
Send out data, it is therefore desirable to network equipment helps UE to carry out different-frequency measure to UE configuration measurement amount interval,
It is not result in again the loss of UE packet simultaneously.
Current UE synchronous regime on MCG and SCG is defined as follows:
Down-going synchronous state: from PCell and PSCell (Primary Secondary Cell Group, major-minor little
District's group) the pointer timing differentials of signal that receives is less than 33us.
Descending asynchronous mode: the pointer timing differentials of the signal received from PCell and PSCell is less than
500us。
Owing to MCG with SCG belongs to two different eNB, and it is cannot to ensure at MCG between different eNB
Will not change with the synchronous regime of SCG.Network equipment to UE configure DC when, meeting
Specify the synchronous regime mode of operation of the upstream or downstream of UE.Current network synchronous regime change time
Waiting, network equipment will no longer be able to normal work to the mode of operation of the corresponding synchronous regime of configuration before UE
Make.
In sum, at present in the case of multi-link, when current network synchronous regime changes, network side
Equipment will no longer be able to normally work to the mode of operation of the corresponding synchronous regime of configuration before UE.

The TAT of the TAG (i.e. the sTAG of synchronous regime change corresponding for SCG) of SCG.
After described terminal carries out timeout treatment to the TAT of MCG and/or SCG, it is possible to according to existing
Operation after the TAT time-out of MCG and/or SCG is carried out.
Such as can perform in following operation is part or all of:
(Hybrid Automatic Repeat reQuest, mixed automatic retransfer please to empty all HARQ of SCG
Ask) caching；
Notice RRC (Radio Resource Control, wireless heterogeneous networks) the release all communities of SCG
PUCCH (Physical Uplink Control Channel, Physical Uplink Control Channel)/SRS (Sounding
Reference Signal, detection reference signal) configuration；
Empty any configuration downlink assignment (downlink distribution) and uplink grant (on
Downlink schedule)；
Think that the TAT of all SCG is overtime.
Operation after the TAT time-out of concrete MCG and/or SCG may refer to 3GPP TS 36.321,
This is not repeating.
Synchronous regime between processing mode two, described terminal notification network equipment MCG and SCG occurs
Change.
Optionally, described terminal by the partly or entirely notice network equipment MCG in following message and
Synchronous regime between SCG changes:
For the information indicating synchronous regime to change；

In force, whether described network equipment judges the synchronous regime between MCG and SCG of terminal
The mode that change occurs has a lot, is set forth below several.
Judgment mode one, described network equipment receive terminal synchronous regime occur change notice after,
Determine that the synchronous regime between MCG and SCG of terminal changes.
Optionally, what described synchronous regime occurred that the notice of change includes in following message is part or all of:
For the information indicating synchronous regime to change；
The Synchronization Status Message that terminal is current；
For indicating synchronous regime that the information of the community changed occurs；

It should be noted that above-mentioned information is merely illustrative, as long as network equipment MCG can be notified
With the synchronous regime between SCG occurs the information of change to be all suitable for the embodiment of the present invention.
Judgment mode two, described network equipment are according to the TAT time-out historical information of SCG, it is judged that terminal
MCG and SCG between synchronous regime whether change.
Optionally, the TAT of described SCG be SCG PCell TAG (i.e. the pTAG's of SCG
The TAT of the TAG (i.e. the sTAG of synchronous regime change corresponding for SCG) of TAT or non-SCG.
After such as terminal carries out timeout treatment to the TAT of MCG and/or SCG, Stochastic accessing mistake can be initiated
Journey；
Accordingly, network equipment can send new TAC order to terminal.Network equipment can basis
The TAT time-out historical information of SCG checks that Multiple through then out TAC dispatch terminal carries out upstream data (or signal)
Sending, terminal the most all cannot send, if it is, the synchronization determined between MCG and SCG of terminal
State changes；Otherwise, it determines the synchronous regime between MCG and SCG of terminal changes.
Wherein concrete needs are checked and rule of thumb by manually configuring, or can be configured by high level several times.
Or, network equipment, sending TAC order to terminal when, starts the TAT intervalometer of network side.
