Description

Based on the communication means of carrier convergence technology and system, base station in heterogeneous network

Technical field

The present invention relates to the communication technology, based on the communication means of carrier convergence technology and system, base station in especially a kind of heterogeneous network.

Background technology

In order to increase communication system capacity, strengthen the network coverage with promote spectrum efficiency, can adopt heterogeneous network (HeterogeneousNetwork, hereinafter referred to as: HetNet) mode carrys out deployable communication system.As shown in Figure 1, for long evolving system, (LongTermEvolution, hereinafter referred to as heterogeneous network schematic diagram LTE).See Fig. 1, in this LTE heterogeneous network, macro base station (MacroeNB, hereinafter referred to as: MeNB) be placed with small base station in coverage, also referred to as micro-base station, such as: femto base station (PicoeNB, hereinafter referred to as: PeNB), Home eNodeB (HomeeNB, hereinafter referred to as: HeNB), millimicro base station (FemtoeNB, hereinafter referred to as: FeNB), relay station (RelayeNB, hereinafter referred to as: ReNB) access point such as, these small base stations can adopt wired or wireless mode to access LTE network.In this LTE heterogeneous network, subscriber equipment (UserEquipment, hereinafter referred to as: under UE) being in the Double mulch of MeNB and small base station, now, the heap(ed) capacity that this communication system can obtain is the capacity sum of MeNB and small base station, compared with the traditional LTE in the past adopting MeNB network configuration, this LTE heterogeneous network communication system comparatively has higher capacity, therefore, under the scenes such as office buildings, market, campus network, usually utilize heterogeneous network mode to dispose these small base stations and MeNB, effectively strengthen the network coverage, promote spectrum efficiency.

Generally can there be one or more community a base station, and under heterogeneous network, UE can only be connected in one of them community, and this community is called the Serving cell of UE.If small base station and MeNB adopt with frequently disposing, all base stations send downstream signal on same carrier wave, comprise descending control domain signal and downlink data territory signal, now, the cell signal that can be subject to another base station when UE communicates with its Serving cell disturbs, and the downstream signal that particularly another base station sends disturbs.As shown in Figure 2, be the interference schematic diagram of in LTE heterogeneous network.In Fig. 2, solid line represents the signal of communication between UE and base station in service sector, and dotted line represents the interference source cell signal that UE is subject to.A UE under PeNB receives the interference of MeNB, is in the 2nd UE in the community of the MeNB near HeNB, owing to not accessing authority, is subject to the interference of HeNB.Usually, the Serving cell of disturbed UE is called victim cell, the community of this UE of interference is called infringement community.

The interference of community to UE in victim cell is encroached in order to reduce in heterogeneous network, third generation partner program (the3rdGenerationPartnershipProject, hereinafter referred to as: (TimeDivisionMultiplexing, hereinafter referred to as TDM) method 3GPP) to propose a kind of time division multiplexing reducing interference in standard.As shown in Figure 3, be the running time-frequency resource distribution schematic diagram in this TDM method.See Fig. 3, the specific running time-frequency resource place of infringement community in some subframe sends signal, other time/frequency source block in these subframes does not send signal, this subframe is called blank subframe or almost blank subframe (AlmostBlankSubframe, hereinafter referred to as: ABS).After adopting this TDM method, reduce the interference of the infringement community that the UE in victim cell is subject at the subframe place encroaching on victim cell corresponding to community empty subframe, thus reach the object reducing infringement community and UE in victim cell is disturbed, therefore, by the mode of ABS sub-frame configuration, the interference achieved between MeNB and small base station controls.

In addition, in order to improve the throughput of heterogeneous network system, multiple component carrier can be configured at MeNB and small base station, by carrier convergence (CarrierAggregation, hereinafter referred to as: CA) technology, by multiple component carrier (ComponentCarrier, hereinafter referred to as: CC) pool the carrier wave that has more large transmission bandwidth, to support the defeated rate of high-speed data.As shown in Figure 4, be a carrier convergence schematic diagram, the CC that the downlink bandwidth of base station is 20M by 5 bandwidth converges, and obtains the system bandwidth of a 100M.

Be similar to the interference realized between MeNB and small base station by the mode of ABS sub-frame configuration in single carrier to control, after adopting CA, also can all adopt ABS mode of operation on multiple CC, the interference carried out between MeNB and small base station controls.

In addition, introduce CA technology in heterogeneous network after, by across carrier dispatching technology, the interference control between MeNB and small base station can also be carried out.Across in carrier dispatching technology, CC not only can dispatch self Physical Downlink Shared Channel, and (PhysicalDownlinkSharedChannel, hereinafter referred to as PDSCH) resource, also can dispatch the PDSCH resource of other CC.In communication process, Physical Downlink Control Channel (PhysicalDownlinkControlChannel, hereinafter referred to as: the schedule information of PDCCH) carrying PDSCH, therefore, to the successful receiving rate of message on PDCCH, directly determine the successful receiving rate to message on PDSCH.That is, if the schedule information that PDCCH sends is decoded unsuccessfully, then cannot obtain the PDSCH resource of being dispatched by this PDCCH, thus cause PDSCH resource to be decoded unsuccessfully.And if the schedule information successfully decoded that PDCCH sends, even if then PDSCH exists certain interference, what communication system also can ensure user data or PDSCH resource by data packet retransmission mechanism or power control mechanism is decoded into power.Therefore, introduce CA technology in heterogeneous network after, the minimum CC of the degree that is disturbed can be selected to be disturbed more CC to dispatch other, that is: the PDCCH schedule information being disturbed more CC being placed on the less CC of the degree of being disturbed sends to UE, to ensure that UE as far as possible correctly receives the schedule information of the PDSCH resource being disturbed more CC.

As shown in Figure 5, in heterogeneous network is across carrier dispatching schematic diagram.For a CC, by reducing transmitting power, MeNB ensure that the coverage of a CC of a CC and PeNB of this MeNB is not overlapping, thus ensure PeNB can use a CC as main component carrier (PrimaryComponentCarrier, hereinafter referred to as: PCC).Because the coverage of the 2nd CC and the 3rd CC overlaps each other, can interfere with each other on the 2nd CC and the 3rd CC between MeNB and PeNB, therefore, a CC can be used to carry out across carrier dispatching the 2nd CC and the 3rd CC.Such as: PeNB can send the schedule information of the PDSCH of the 2nd CC and the 3rd CC on the PDCCH of a CC to a UE, ensure that a UE correctly can receive the schedule information of the PDSCH of the 2nd CC and the 3rd CC, thus use the PDSCH resource of the 2nd CC and the 3rd CC.And the interference that PDSCH resource for the 2nd CC and the 3rd CC exists, retransmission mechanism or power control mechanism can be passed through, improve and be decoded into power by PDSCH transmission packet on the 2nd CC and the 3rd CC.

In existing heterogeneous network on single carrier, MeNB to small base station except limiting to some extent in ABS sub-frame configuration mode, separate in the work of other side MeNB and small base station.Realizing in process of the present invention, inventor finds, introduce CA technology in heterogeneous network after, all small base stations in a MeNB coverage all may activate CC arbitrarily according to self-demand, when base station in heterogeneous network adopts ABS mode of operation, if each small base station selects different CC as ABSCC all independently, just need MeNB that whole or most of CC is configured to ABSCC, because MeNB is at ABS subframe signal transmission hardly, the throughput of whole communication system is caused sharply to decline; Equally, when base station in heterogeneous network adopts across carrier dispatching technology, if each small base station selects CC as the PCC of oneself all independently, may need MeNB that whole or most of CC is abdicated the PCC being used as small base station, cause MeNB to abdicate being used as the coverage of this part CC of small base station PCC to reduce, thus the performance of MeNB is sharply declined.Therefore, after prior art introduces CA technology in heterogeneous network, adopt the TDM method reducing interference or the poor effect of carrying out the interference control between MeNB and small base station across carrier dispatching technology.
