Description

A kind of method and apparatus for being used to handle interference data

Technical field

The present invention relates to communication technical field, more particularly to a kind of technology for being used to handle interference data.

Background technology

At present over the mobile network to support the growing demand of the data application of higher throughput and spectrum efficiency, Demand has been driven to go exploitation to be based on OFDM (OFDM, Orthogonal Frequency Division Multiplexing forth generation (4G) network), including WiMAX (Worldwide Interoperability for Microwave Access, worldwide interoperability for microwave accesses), 3GPP LTE (The3rd Generation Partnership Proiect Long Term Evolution, 3rd Generation Partnership Project Long Term Evolution) and LTE-A (LTE-Advanced).Having Have the area of intensive cell, LTE and LET-A are interference limiting systems, for example, when macrocell and picocell combination by with When in heterogeneous network.Therefore, one of LTE and the emphasis research topic of lte-a system be Inter-Cell Interference Coordination (ICIC, inter-cellinterference coordination)。

Discussion for Release-8/9, based on RNTP (Relative Narrowband TX Power, with respect to arrowband Transmission power)/HII (High interference Indicator, high interference instruction)/OI (Overload Indicator, Overload instruction) ICIC proposed between macrocell.For the discussion of issue -10, CoMP (Coordinated Multiple Points, cooperate with multicast communication) and almost blank subframe is proposed for the interference coordination between macrocell and cell.It is right In Release-11, for further improving performance, specific cell reference signal (CRS, cell- with network assistance Specific reference signal) AF panel/elimination further enhance inter-cell interference (FeICIC, Further enhanced inter-cellinterference) it is suggested.However, discussed in Release-11FeiCIC AF panel/removing method, be only confined in remove adjacent cell CRS to this cell PDSCH (Physical Downlink Shared Channel, Physical Downlink Shared Channel) interference, and do not consider interference of the adjacent cell PDSCH to this cell PDSCH Corresponding interference elimination method.

However, increased to improve capacity with tackling the business of index, more dense cell deployment (such as heterogeneous network (HetNet, heterogeneous network)) and improve spectrum efficiency be all necessary.To realize that higher network holds Amount, the cochannel interference of the user in cell either dispatched from minizone or jointly are estimated as the higher net of realization The key constraints of network capacity.Compared with the coordination of transmission equipment side, the AF panel of receiving terminal or cancellation can also be shown significantly Performance gain.Serial interference elimination (SIC, Successive interference cancellation) and parallel interference disappear Outstanding performance can be provided except (PIC, Parallel interference cancellation) has been demonstrated in academia.Understanding To these benefits, RAN#59 approveds one new research project, the network assistance interference on LTE Release-12 disappear Remove and suppress (NAICS, Network-Assisted Interference Cancellation and Suppression), with Its benefit is assessed, and inquires into the feasible methods of NAICS.

In NAICS, network to disturbed UE provide interfered cell downlink transfer information, so as to this is disturbed UE can Perform interference elimination/suppression (IC/IS).We are with reference to downlink transfer information as NAICS information.NAICS information can be by such as The serving cell of the first mechanism shown in Fig. 1 is sent to disturbed UE, or the interference by the second mechanism as shown in Figure 1 Cell is sent to disturbed UE.In view of the dynamic characteristic of scheduling, and the cells that are related to of NAICS and disturbed UE service it is small Between base station between area interaction corresponding to interface X2 link coordination delay, the second mechanism in implementation process may it is more efficient and Effectively.

In RAN1#73, it has been agreed that NAICS will be focused on PDSCH physical channels.Therefore, NAICS information needs to carry For decoding (such as modulation ＆TBS (Transport Block Size, transport block size)) information of the PDSCH (s) in interfered cell With schedule information (PRBs (Physical Resource Block, Physical Resource Block) position).It can quilt：

Directly transmit, for example, with comprising on disturbing PDSCH decoding and (E) PDCCH of schedule information ((Enhanced) Physical Downlink Shared Control Channel, (enhancing) Physical Downlink Control Channel) shape Control signaling (E) PDCCH all schedule informations included are directly issued disturbed UE and performed by formula, i.e., such a mode NAICS；

Here, illustrated by taking the USS transmission based on PDCCH as an example：Believe for the particular schedule of second user equipment UE Breath will be transmitted by PDCCH rather than EPDCCH, before the first user equipment 3 performs NAICS, corresponding to NAICS PRBs' Schedule information from neighbor cell (e.g., the NAICS corresponding to the second base station 2 is related to cell) is also required to by the first user equipment 3 decodings, because the PDCCH of existing serving cell is decoded in a manner of blind decoding, similar blind decoding mode is also related to small by NAICS Area uses, and to perform the PDCCH blind decodings that NAICS is related to cell, the first user equipment 3 needs to know following information：A) synchronous ＆ CRS configuration ＆PBCH notices；B) PDSCH original position (PCFICH information)；c)C-RNIT.If in addition, in BL decoded numbers In do not limit, will cause plus position BL quantity for NAICS Target cell.When the first user equipment 3 performs NAICS, it is Too many complexity and parameter is avoided to consume, supporting the sum of BL quantity should not be further improved, and the high AL of reasonable employment can Keep the robustness of PDCCH reception.In addition, for interfered cell, because it also has experience dry from second user equipment The relatively high likelihood disturbed, AL can also be limited in certain level, such as limit higher level.Example is used as using PDCCHUSS Son, if the AL levels that serving cell and NAICS are related to cell are limited to AL4 and AL8, the first user equipment 3 needs reality The quantity of blind check will be reduced to 16 ({ 2,2 } x2x2) from 64 ({ 6,6,2,2 } x2x2), compared with no limitation AL scheme, the One user equipment 3 needs the quantity of actual blind check to substantially reduce.

Pass through high-level signaling such as RRC signaling by the limitation aggregation level and user equipment of the second user equipment when using When identification information is notified to the first user equipment 3, corresponding high-level signaling such as RRC signaling can be as follows：

PDSCH- configuration information units

In addition, linking enhancing on the X2 between the corresponding first base station 1 of information above and the second base station 2 should be designed, Design being exemplified below shown in table 1 for corresponding X2 link signalings：

Table 1

Preferably, first base station 1 can be by the limitation aggregation level and customer equipment identification information of the second user equipment First user equipment 3 is sent in advance, for example, several sub-frame transmissions before actual interference, this allows the first user Equipment 3 prepares its receiver for being used to disturb elimination.
