It can be specific user equipment (UE) service between the transfer point of finite data.Implementation method commonly used in the trade at present mainly has two
Kind: first is that network is divided into mutually disjoint cooperative cluster, scheduling need to only carry out between base station in cluster, and the base station in same cluster is only
To be positioned at the user service in cluster, as shown in Figure 1.This COMP band plan implementation method, complexity are low, it is easy to accomplish,
But throughput gain is limited, because collaboration region is fixed, main interference source is caused often not to be cancelled.Second is that based on every
The most strong interferers of a COMP user determine that it is most suitable for cooperation cell set, and this available relatively high performance of method increases
Benefit, but since this method is determined based on UE, the size or shape of collaboration region be it is uncertain, corresponding to different
COMP user collaboration region is likely to be overlapping, needs the coordination between all overlapping collaboration regions, from the point of view of scheduling,
Implementation complexity is higher.

7. according to the method described in claim 6, it is characterized in that, if the cooperation cell of the COMP user be 1, PCI
Value sequence is to be carried out in cluster using cooperation cell segmentation orthogonal method.
If 8. the method according to the description of claim 7 is characterized in that the cooperation cell of the COMP user be 1,
PCI value sequence is to be carried out in cluster using cooperation cell segmentation orthogonal method, comprising:
If the cooperation cell that the host cell in cluster has different COMP users to be respectively necessary for an x=1 or x=2, and NUM-
The range to cooperate for this cluster second community is then divided into three sections, tri- sections of corresponding PCI of POS-COcell1 by COcellx=P=3
Mod 3 value sequence is 0,1, tri- sections of 2, POS-COcell2 corresponding 3 values of PCI mod be sequentially 2,0,1.
9. method a method according to any one of claims 6-8, which is characterized in that the first community is small according to described first
The first information that each second community is sent in the first information and this cluster in area, determines the band information of all cells in the cluster,
Include:
When all cell NUM-COMP=1 of the first community in this cluster, COMP band resource trisection takes according to x
The every cell of the sequence of value accounts for a copy of it；
The first community, there are two when cell NUM-COMP=1, COMP band resource is halved, is taken according to x in this cluster
Two cells of the sequence of the value NUM-COMP=1 respectively account for a copy of it；
When all cell NUM-COMP=0 of the first community in this cluster, COMP band resource is not divided；
Wherein, the size of COMP band resource is obtained under the premise of guaranteeing central user QoS, COMP band resource it is big
It is small are as follows: M × α, α ∈ [0,1], M are network system band resource.
