Description
Technical field
The present invention relates in general to the improvement in the carrier type in process wired or wireless communication system.More specifically, the present invention is devoted to for the equipment of the ambulant enhancing system information transmissions of new carrier type and/or switching command, method and computer program.
Background technology
Self-existent new carrier type (SA-NCT) is considered to one of the staple of conversation of the Long Term Evolution LTE in 3GPP version 12 (Rel-12) enhancing.
3GPP version 11 is that many features of defining bring change in the earlier version with the new carrier type (R11NCT) that dependent exists.Feature (such as, replace the enhancing physical downlink control channel (ePDCCH) of physical downlink control channel PDCCH, wherein, control channel is no longer fixed to certain temporal frequency resource, if but not exclusively remove, at least obviously reduce more flexible allocation and specific (sharing) the reference signal CRS in community.In addition, the Dynamic System on NCT is now mainly based on channel state information reference signals CSI-RS and demodulated reference signal DM-RS but not the specific reference signal CRS in community.
Under those changes that 3GPP version 11 brings, make the new self-existent carrier type not having CRS and Traditional control channel can not need a lot of change.This change mainly comprises initial access and mobility measurements.

Newly built construction project WI according to the new carrier type of 3GPP version 12 (Rel-12) illustrates, new feature Ke Shi NCT community has some new flexibility, such as:
-flexibly CSI-RS configuration, there is no CRS or low-down CRS, energy saver mode, NCT also can with self-existent (SA), CA or grand auxiliary mode running; And
-available convention carrier mixed deployment during the migration cycle.
According to the Inter-Cell Interference Coordination eICIC topic strengthened, some schemes for strengthening system information transmissions are discussed.Such as, in [3], mention following possibility;
If-needing signaling, under the existence of the main interference be biased at 9dB, feasible eNB signaling solution makes the example of the detection obviously improving Physical Broadcast Channel PBCH and/or system information block 1SIB1; And
-victim cell can use the signaling of the higher level in shielded subframe that its system information is sent to user equipment (UE).
In [4], agreement is following is working hypothesis:
-under the existence with the main interference that 9dB is biased, help the eNB signaling solution detecting PBCH;
-during the switching from macrocell to victim cell, macrocell also can provide Master Information Block mib information involved in from victim cell; And
The Single Frequency Network SFN offset between-victim cell and macrocell.
But the emphasis of these solutions is to provide system information in locked resource to avoid interference, and these system informations or switching command do not relate to any information about new carrier type.
In [5], coordinate the CSI-RS configuration of multiple spot CoMP measurement with following agreement discussion:
-suppose that the CSI-RS that UE measures clearly is configured by network N W, that is, do not need the blind Detecting of the CSI-RS in UE; And
-CSI-RS specifically configured the part (be associated for how to make them and measure to configure and how mention their further research in measurement report) being configured to measurement object.
These configuration application of UE are configured with CoMP transmission pattern but do not relate to system information acquisition and also do not switch to new carrier type.
But, these new features can cause UE detect, switch and measure obscure.Such as, recognize there is Rel-12 carrier wave or convention carrier before UE may need a lot of possibility of blind detection, if or even some CSI-RS be used for blind detection in some neighbor cell.This makes UE implement complicated and may bring very unnecessary huge power consumption, and measurement time delay also may be made longer.In addition, in Rel-12, system may process a large amount of neighbor cells (intensive little community), and this even makes this problem more serious.
Therefore, need to optimize the fast access with regard to RC connects and switching and switching flow.

In order to UE is redirected to small-cell during RRC connection establishment program, eNB needs the RRCconnectionReject be inserted into by some new signals in Msg4, and also before this, eNB needs some the general knowledge had about UE information, such as, reason, UE version etc. is set up.This can make eNB execution process unload/be redirected, and also UE speed can be taken into account, and it is redirected to help in Msg3 some initial measurement can be reported to eNB.
Advantages more of the present invention are as follows:
-for first aspect:
O is for dense deployment (neighbor cell number is large) or mixed deployment (supposing to dispose frequently than dew carrier wave or convention carrier), and proposal can help UE to simplify its blind detection, power saving reduce switching delay.
-for second aspect, compared with setting up with first, online in macrocell and then carry out HO program, it is passable
O avoids communication disruption (can use and be easy to dispose->S1 interface) owing to may there is no the possibility of X2 interface between macrocell and small-cell
If o UE covers small-cell, so HO flow process can be regarded as too high and unnecessary
O is by considering UE reason for claim, communication delay sensitivity, load condition, tradition and new UE number etc., and eNB has better elasticity when the initial access of control UE.
