Certainly, but this mode is carried out between the base station based on equal standing, so the negotiation between base station is no mandatory, interference
The source scheduling mode for coordinating to need is suggestion formula, rather than the scheduling under unified control.For macro base station, due to base
Farther out, the interference between base station is not too greatly that this mode held consultations on an equal footing is feasible to spacing between standing.
But under macro and micro networks scene or pico- networking scene, since spacing is smaller between base station, so between base station
Interfere it is more serious, if being difficult to avoid doing by resource coordination still by the way of holding consultations on an equal footing between this base station
It disturbs.This is because each base station can face the interference from many adjacent micro-base stations, base station will simultaneously with it is each around
Base station carries out resource coordination, and the feedback speed of each base station is also different, and this reduces the speed that radio resource is coordinated, will
Due interference coordination effect is not had.If guaranteeing that there is smaller interference in neighboring community, it is small that itself may be faced with
Area does not have the condition that resource can be used.
