Description
Technical field
The present invention relates to wireless communication technology field, particularly relate to a kind of method of network assistance interference delete, device, system and relevant device.
Background technology
Network assistance interference delete (NAICS) refer to terminal configuration advanced receivers, utilize the interfere information that network side notifies, in conjunction with self blind check, carry out effectively deleting to promote receptivity to interference.
Respectively as depicted in figs. 1 and 2, wherein, Fig. 1 is presence of intercell interference schematic diagram.Fig. 2 is network assistance interference delete schematic diagram.Terminal is in order to carry out effective interference delete, need the supplementary obtained from network side to comprise following two classes: a class is the supplementary of cell level (Cell-specific), comprise system bandwidth, synchronous instruction and CellID (cell ID of adjacent area), CRSPorts (public reference signal port) and PA parameter and PB parameter, another kind of is the supplementary of user class (User-specific), comprise CSI-RS (ChannelStatusInformationReferenceSignal, channel state information reference signals), TM (TransmissionMode, transmission mode), RI (RankIndication, order indicates), PMI (PrecodingMatrixIndicator, pre-coding matrix indicates), PA parameter, MCS (ModulationandCodingScheme, modulation and coding strategy) DMRSPorts (demodulated reference signal port), DMRSVCID (demodulated reference signal virtual subdistrict mark), resource allocation type and Resourse Distribute granularity etc.
Current 3GPP (third generation partner program) is discussing terminal and how to obtain these supplementarys, and which supplementary can utilize high-level signaling to notify, which can be obtained by terminal self blind check.Wherein, the supplementary change relevant due to Cell-Specific is slower, and the expense utilizing high-level signaling to notify is less, therefore, intercorrelation information between base station can be considered, high-level signaling is utilized to notify the supplementary that UE is current by the ServingCell (Serving cell) of UE (UserEquipment, subscriber equipment) again.
But due to the flexibility of interference base station scheduling, the supplementary that UE-specific is correlated with is dynamic change, if still utilize high-level signaling to notify, cause that interaction time delay between base station is longer and expense is larger.
Wherein, resource allocation type in the supplementary that User-specific is correlated with comprises DVRB (DistributedVirtualResourceBlock, distributed virtual resource block) and LVRB (LocalizedVirtualResourceBlock, localized virtual resource block) two kinds of mapping modes, as shown in Figure 3, for DVRB and LVRB Resourse Distribute schematic diagram, for LVRB, VRB (VirtualResourceBlock, virtual resource blocks) sequence number and PRB (PhysicalResourceBlock, Physical Resource Block) sequence number is one to one, so LVRB is centralized distribution on physical resource.For DVRB, two time slots (slot) of each VRB in a subframe are mapped on different PRB, and namely two same VRB of time slot are mapped on different PRB, there is a Gap value between them.
If neighbor base station uses DVRB mode to dispatch, the terminal in Serving cell can only according to the data blind check of a slot when carrying out NAICS, however now RAN4 be detected as the data that supposition UE blind check at least needs two slot.So NAICS will cause the NAICS performance of terminal not good when neighbor base station scheduling adopts DVRB to map.If do not allow neighbor base station to use DVRB mode to dispatch, only use LDVB mode to dispatch, like this, because the dispatching flexibility of neighbor base station reduces, adjacent area overall performance is also affected.
