Technical field
The present invention relates to the communications field, more specifically, the present invention relates to the method and apparatus be used to the operation that configures new carrier type (NCT) carrier wave.
Background technology
According to current standardization effort, in advanced Long Term Evolution project (LTE-A) R11, will support new carrier type (NCT) carrier wave of down link (DL), and have following feature:
NCT is linked to an existing DL carrier component (CC) and this link is that subscriber equipment (UE) is specific.NCT to be linked to a uplink carrier component (UL CC) to form a traditional Scell (from the residential quarter).
Concerning the user, NCT can be synchronous (S-NCT) or asynchronous (N-NCT), and this depends on reception (Rx) feature of UE.
For synchronous NCT carrier wave, its operation depends on the traditional DL CC that links, and for example DL synchronously, DL Rx Timing measurement, DL PL (downlink path-loss) measure etc.
And for asynchronous NCT carrier wave, the DL that UE need to carry out relevant NCT carrier wave measures, and comprises that DL is synchronous, DL PL measures etc.
In addition, in RAN2R11 (Access Network 2 versions 11), for (Scell) reaches an agreement with regard to following principle from the residential quarter:
--if Scell belongs to main timing advance group (pTAG), and then the reference of its uplink timing will be main plot (Pcell).Its path loss is with reference to DL CC or the Pcell that can be its SIB2 link.
--if Scell belongs to from timing advance group (sTAG), then:
Uplink timing is with reference to being the DL CC that implements the Scell of random access procedure among this sTAG;
The path loss of Scell is with reference to the DL CC that will be the SIB2 link of this Scell;
Pcell can not be used as uplink timing reference and the PL reference of the Scell of sTAG.
Scell separates activation dominantly or recessively.The former realizes by the eNB down order, and the latter is because deexcitation timer expiration or overflow.

Embodiment
Come the specific embodiment of the present invention is described in detail below in conjunction with accompanying drawing.In the following description, for illustrative purposes, many details have been set forth, in order to the thorough understanding to embodiments of the invention is provided.Yet, it is apparent to those skilled in the art that embodiments of the invention can be in the situation that do not have these detail practices or utilize the layout that is equal to put into practice.In other examples, show known structure and equipment with the form of block diagram, to avoid unnecessarily bluring embodiments of the invention.
Method and apparatus for the operation that configures new carrier type (NCT) carrier wave has below been described in more detail.
Fig. 1 shows the wireless communication system 100 that the present invention can implement therein.For example, in this wireless communication system 100, wherein the NCT carrier wave can be configured in wherein.
In wireless communication system 100, a UE can come to communicate with eNB by a plurality of carrier components (CC) in up, descending difference.If for a UE, eNB thinks that these CC can share a timing advance (TA) value, be eNB as long as adjust the TA value with reference to any one up transmitted signal among these CC, this TA value can be used by these CC, thinks that then these CC belong to a timing advance group (TAG).
When UE set up the RRC connection for the first time, eNB was only to UE configuration a Serving cell, i.e. main plot (Pcell).The carrier wave of Pcell is called main carrier component (PCC).
According to considerations such as load, QoS demands, eNB can configure one or more extra-services residential quarter to UE, i.e. from the residential quarter (Scell).The carrier wave of Scell is called from carrier component (SCC).
That is to say, UE only has a Pcell, and in Frequency Division Duplexing (FDD) (FDD) system, this Pcell only has a UL CC and a descending DL CC.A UE can have one or more Scell, and each Scell also only has a DL CC and/or a UL CC.Certainly, in time division duplex (TDD) system, Pcell and Scell only have a carrier wave, are used for uplink and downlink.
In addition, UE only has a pTAG, and this pTAG comprises Pcell, 0 or 1 or more Scell.And UE can have 0 or one or more sTAG, and a sTAG can have one or more Scell.
That is to say, the TAG that the CC of Pcell belongs to is pTAG, and TAG in addition is sTAG.
As shown in Figure 1, as an example, wireless communication system 100 comprises an eNB 110 and a UE 120.Certainly, those skilled in the art will appreciate that system 100 can also comprise more eNB 110 and the UE 120 of more number.
UE 120 can be mobile phone, panel computer, notebook computer, desktop computer, personal digital assistant (PDA) etc.In addition, between eNB 110 and UE 120, have Pcell 130 and 4 Scell 140-1,140-2,140-3,140-4.Certainly, those skilled in the art will appreciate that the number of Scell can be more or less, different cell can have different paths.
Here, be without loss of generality, suppose that Pcell 130 and Scell 140-4 belong to pTAG, Scell140-2 and Scell 140-3 belong to sTAG 1, and Scell 140-1 belongs to sTAG 2.
In LTE-A R11, introduced the concept of new carrier type (NCT), NCT carrier wave (not shown) can not use separately, realizes communicating by letter between UE and the eNB thereby it need to link with existing carrier wave.Therefore, thus need to be configured the communication that realizes on it to the NCT carrier wave.
According to current RAN1 state, NCT is reached an agreement for R11: the NCT carrier wave comprises two kinds of different types: synchronous (S-NCT) and asynchronous (S-NCT).For the S-NCT carrier wave, UE does not need that this S-NCT carrier wave is carried out DL and measures, thereby because UE can obtain from the DL CC that the S-NCT carrier wave links to help to obtain relevant information, thereby reaching the synchronous purpose of DL, this has alleviated the burden of UE.Then, for UE, need to be for some traditional DL signalings of this S-NCT, for example PSS/SS, CRS, PDCCH yet.And for asynchronous S-NCT carrier wave, the DL that UE has to be correlated with measures to guarantee its proper operation.Then, for UE, need to be for some traditional DL signalings of this S-NCT, although for example PSS/SS, CRS, PDCCH---also up to now determined and whether can so operate.
Therefore, method and apparatus according to the operation of configuration of the present invention NCT carrier wave is described below with reference to accompanying drawings.
