Long Term Evolution (LongTermEvolution, LTE) is descending have employed OFDM (OrthogonalFrequencyDivisionMultiplexing, OFDM) technology, and the problem of intra-cell interference is resolved substantially.But its presence of intercell interference (Inter-CellInterference, ICI) is even more serious than code division multiple access (CodeDivisionMultipleAccess, CDMA) system.
In order to coordinate minizone co-channel interference, Inter-Cell Interference Coordination (Inter-CellInterferenceCoordination, ICIC) technology is used in LTE networking.ICIC technology basic thought by managing radio resources, presence of intercell interference is controlled, and is a kind ofly to consider that resource in multiple community uses and the situation such as load and the multiple cell radio resource management techniques of carrying out.
ICIC technology is one radio resource management techniques at a slow speed, and ICIC technology is by limiting the use of Radio Resource in each community, comprise the use of restriction running time-frequency resource or limit its transmitting power on certain running time-frequency resource, reduce the spectrum efficiency of Radio Resource, therefore coordinated multipoint transmission and reception (CoordinatedMultiplePointsTransmission/Reception, CoMP) technology is introduced in LTE protocol version R10 agreement.
CoMP technology refers to the community of multiple base stations that geographical position is separated, work in coordination with is that a user transmits data---Physical Downlink Shared Channel (PhysicalDownlinkSharedChannel, or combine data---the Physical Uplink Shared Channel (PhysicalUplinkSharedChannel, PUSCH) that reception user sends PDSCH).The object introducing this technology reduces the interference of minizone, the spectrum efficiency of the spectrum efficiency of elevator system, particularly Cell Edge User.
CoMP technology is a kind of fast wireless resource management techniques, every Transmission Time Interval (TransmissionTimeInterval, TTI) all needs the channel condition information and schedule information etc. (wherein the TTI of LTE is 1ms) of shared minizone data message, user; Big data quantity is moved and the data of high real-time requirement are transferred to the huge pressure of current base station equipment and networking band, seriously limits the effect of CoMP technology in extensive multiple cell interference coordination.
Based on the various restrictions of CoMP technology above and ICIC technology, CoMP and ICIC Collaborative (CoordinationofCoMP & ICIC is have employed in existing network, Co_CoMP_ICIC) scheme carries out co-channel interference coordinate scheme, as shown in Figure 1, is specifically described as follows.
First, be littlely distinguished into some groups existing during networking, often group generally comprises 5 ~ 6 stylobate stations, and often group is a CoMP cooperative groups;
Secondly, set up a centralized ICIC control appliance, magnitude control generally can reach 3000 cell level, and the ICIC that this equipment is responsible for the whole network rank coordinates;
Finally, adopt CoMP technology to carry out interference coordination in IntraCoMP cooperative groups, between InterCoMP cooperative groups, adopt ICIC technology to disturb.
The program (in CoMP cooperative groups) among a small circle adopts CoMP technology, reduces the mutual load of data between a base station to a certain extent; In on a large scale, (between CoMP cooperative groups) adopts ICIC technology, reduces the loss of spectrum efficiency to a certain extent.The combination of two kinds of technology achieves co-channel interference preferably and coordinates.
Existing scheme adopts the mode of static division grouping to the division of CoMP cooperative groups, and namely when networking, the community of the whole network is divided into several CoMP cooperative groups according to relative position, except unartificial amendment, this compound mode will be run down always.
But in the network of reality, user is often in mobile status, is easy to the gathering scene forming edge customer, causes the unbalance of network cell edge load, namely at some edge, overlapping cell, user assembles, and causes the network load that this region is larger; And in some overlapping community, user leaves, the network load in this region is lighter.The scheme of existing static division grouping cannot adapt to user and move the scene causing cell edge network load unbalance, can not realize the optimum distribution of Radio Resource well.
