What deserves to be explained is, because the region of inner circle community is covered by inner circle community and cylindrical community simultaneously, UE can monitor the spectrum information of the first community and the frequency spectrum resource of the second community; UE can monitor the signal message of inner circle community and the signal message of cylindrical community (at least can comprise signal strength signal intensity and signal quality), and the signal message monitoring is sent to the first base station; The first base station selection signal intensity great community or selection signal quality Gao community are accessed for UE.It is emphasized that, because the coverage of inner circle community is less than the coverage of cylindrical community, so in the coverage of inner circle community, the signal strength signal intensity of inner circle community and signal quality are higher than cylindrical community, that is to say, in the present embodiment, the UE that is positioned at inner circle cell range can be used the frequency spectrum resource (i.e. the frequency spectrum resource of the second community) of inner circle community to communicate.Aforesaid way is a kind of method of carrying out signal selection in inner circle community, also can adopt other modes to determine to use the frequency spectrum resource of inner circle community, such as the variety of way such as determine according to the distance of UE and base station, repeats no more herein.
In cellular network communicating system, generally adopt the frequency reuse of M*N to determine frequency planning method.Wherein, M represents base station number, and N represents the number of cells of each BTS management, and ZeM*NGe community forms a channeling bunch.The communication system of the frequency-division multiplexing method that employing the present embodiment provides comprises a plurality of channelings bunch, and each different channeling bunch frequency spectrum resource that can use is identical.
In the present embodiment, take the first community to describe as example, the processing method of other communities in same channeling bunch is identical with the first community.By determine two independently community (inner circle community and cylindrical communities) in community, make to belong between the inside and outside circle community of different base station multiplexing frequency spectrum resource each other mutually, thereby can make the spectrum capabilities of whole communication system at least obtain double growth.The scheme that adopts the embodiment of the present invention to provide, in channeling bunch, for the first community and the second community that do not belong to same base station, no matter whether described the first community and the second community are neighbor cell, all multiplexing frequency spectrum resource each other mutually.
Concrete, when described the first community and the second community are non-adjacent community, because co-channel interference can be effectively suppressed, so multiplexing frequency spectrum resource each other mutually; When described the first community and the second community are neighbor cell; the method that adopts the present embodiment to provide; owing to there being the subregion (this part region can be understood as the protection zone that the inner circle community avoided in the first community and the second community interfere with each other) of the cylindrical community of the first community between the inner circle community in the first community and the second community; so; between the inner circle community of the first community and the second community, can effectively suppress co-channel interference, thereby allow the frequency spectrum resource that the inner circle community of the first community can multiplexing the second community.Adopt identical method, more frequency spectrum resource also can be used by the mode of channeling in the second community.
What the embodiment of the present invention provided carries out the method for frequency division multiplexing to frequency spectrum resource; by determine inner circle community and Liang Ge individual cell, cylindrical community in the first community; owing to existing the subregion of cylindrical community as co-channel interference protection zone between the inner circle community in the first community and the second community; so the frequency spectrum resource that inner circle community can multiplexing the second community (the second community and the first community belong to different base station), thereby can effectively promote the capacity of Traffic Channel in communication system.
Embodiment bis-
On basis embodiment illustrated in fig. 1, the embodiment of the present invention further provides a kind of method of frequency spectrum resource being carried out to frequency division multiplexing, and as described in Figure 2, described method comprises:
201, inner circle community and cylindrical community are determined in the first base station in the first community, and described inner circle community and cylindrical community are individual cell.

What deserves to be explained is, the present embodiment be take the first community and is described as example, and it is multiplexing that other communities can adopt similar method to carry out frequency spectrum resource, and the present embodiment repeats no longer one by one.
Optionally, described the first base station can be adopted and in the first community, be determined with the following method inner circle community and cylindrical community:
Method one:
At the first base station configuration AAS, by described AAS, in described the first community, determine inner circle community and cylindrical community.
Method two:
At the first base station configuration double antenna, by described double antenna, in described the first community, determine inner circle community and cylindrical community.
202, described the first base station by described AAS or double antenna, sends respectively BCCH signal at described inner circle community A1 and cylindrical community A4, so that UE measures the signal strength signal intensity of described inner circle community A1 while initiating switching from cylindrical community A4 to inner circle community A1.
