Description
Technical field
The present invention relates to mobile communication technology field, more particularly to a kind of inter-cell interference coordination method and system.
Background technology
During LTE identical networkings, co-channel interference can be produced between neighbor cell, at present the main skill of LTE system Cochannel interference
Art is Inter-Cell Interference Coordination ICIC technologies.
It is up to use dynamic I CIC technologies in 3GPP standards, high interference is transmitted by X2 interface and indicates that HII and overload indicate
OI information.HII passes through resource for pointing out to distribute to the Physical Resource Block PRB for being likely to result in larger interference of edge customer
Collision free is dispatched, reduces interference.OI is used to point out those PRB for being subjected to larger interference, prevents it to be assigned to side again
Edge user.When the result that the algorithm that the network equipment uses is drawn is more than the HII thresholdings of setting, the PRB is marked as HII,
And sending adjacent cell to, different HII can be transmitted in different adjacent cells.When uplink channel interference is prescribed a time limit more than trigger gate, cell
OI is sent to neighbor cell to indicate the uplink channel interference situation in this Intra-cell.It is descending to use relative narrow emission work(
Rate RNTP parameters indicate each PRB power information, can be shifted to an earlier date this cell PRB power information by transmitting RNTP parameters
Adjacent cell is notified, adjacent cell carries out interference coordination according to the power information received, so as to lower inter-cell interference.In standard
RNTP only indicates whether some PRB is occupied using 1bit, and R8 supports interaction RNTP information between base station.For uplink and downlink,
PRB resources are scheduled by base station.
The frequency that limitation according to using Radio Resource is updated, ICIC points are 4 major classes:
Static coordination:The time that use limitation to Radio Resource is reconfigured is some days, with little need for base
Interactive information between standing.
It is semi-static:The time that use limitation to Radio Resource is reconfigured is second level or longer, is believed between base station
The frequency that breath transmits is tens seconds or minute level.
Dynamic coordinate:Use time for being reconfigured of limitation to Radio Resource is tens or hundreds of milliseconds, base station
Between information transmission frequency it is similar.
Cooperative scheduling:The time that use limitation to Radio Resource is reconfigured is TTI millisecond ranks, because X2 connects
The time delay limitation of mouth, can not transmission information between base station.
Interim is being reconfigured twice, and some original no futures may be there may be the PRB of interference HII marks
Through more than HII thresholdings, but it will not be marked as HII before reconfiguring and be sent to neighbor cell base station, if neighbor cell
These PRB are distributed to edge customer and used by base station, can cause inter-cell interference;And some PRB for having been marked as HII may
Already below HII thresholdings, these PRB will not cause the wave of resource by neighbor cell allocation to edge customer before reconfiguring
Take.Similarly, reconfiguring interim twice, it is some be not marked with over occurred to disturb OI PRB to surpass
OI thresholdings are crossed, but will not be marked as OI before reconfiguring and be sent to neighbor cell, neighbor cell may be by these PRB points
Dispensing edge customer, cause edge customer using these PRB by inter-cell interference, and some PRB for having been marked as OI
May be already below OI thresholdings, but will not be removed OI before reconfiguring and mark and be sent to neighbor cell base station, these PRB
Edge customer use will not be distributed to by neighbor cell base station, causes the waste of resource.
Shortening reconfigures interval twice, such as semi-static coordination or dynamic coordinate, can reduce inter-cell interference and resource
Waste, but the load of X2 interface can be increased.In addition, using semi-static coordination or dynamic coordinate, being needed in the network planning can
That leans on estimates pattern, while needs to consider different vendor using the problems such as cooperation is difficult caused by different ICIC algorithms.Therefore, lacking
It is weary reliable when estimating pattern, it is difficult the effect obtained using semi-static coordination or dynamic coordinate.
