Sector splitting technique and more sectors are total to cell networking technology to promote the power system capacity of network and covering quality.
Sector splitting technique refers to a physical area splitting into multiple physical areas, so that same base station is covered
The number of physical area increases in cover area, so as to promote the power system capacity of base station.
For example, in Fig. 1 using sector splitting technique by three conventional physical cell splittings under same base station into six objects
Cell is managed, Cell0 is split into Cell00 and Cell01, Cell1 is split into Cell10 and Cell11, Cell2 is split into
Cell20 and Cell21.
The shortcomings that sector splitting technique, includes at following 2 points：
First, sector splitting technique causes the number of physical area in the overlay area of base station to increase, soft handover is resulted in
Ratio is promoted, and so as to increase the consumption of resource, reduces the performance of system；
Second, in order to ensure the continuous covering of signal, in the splitting technique of sector, wave that the antenna of contiguous physical cell is sent out
Beam has certain crossover region, and the angle spread effect of wave beam can then cause the area of the crossover region larger in wireless network,
In this way, the user equipment positioned at the crossover region（User Equipment, UE）Leading from different physical areas will be received
Frequency signal, and the power of these pilot signals is more similar, increases which results in pilot pollution and adjacent area interference, and then reduces
Key Performance Indicator during UE communication（Key Performance Indicator, KPI）.
More sectors are total to cell networking technology, are received by sector transmission sector（Sector Transmit Sector
Receive, STSR）One physical area splitting can be multiple sectors by technology, then, will be cleaved by same physical area
Obtained from the common signal channels of multiple sectors merge, so as to which these sectors are merged into a virtual subdistrict.
In order to ensure continuously to cover, the wave beam of adjacent sectors has certain crossover region after cell splitting, in addition wireless environment
The angle spread of middle wave beam acts on, and overlay region will become larger between adjacent beams, and is surveyed from actual environment, in virtual small
The UE of wave beam crossover region in area cannot carry out resource multiplex, and cell capacity promotion is very limited, also, the sector cleaved out is got over
More, overlay region bigger will be more serious for the restricted problem of resource multiplex.

Illustrate the preferred embodiment of the present invention one with reference to Fig. 4 A.
Assuming that in Fig. 4 A, the base station of cell A has "-four radio-frequency channel of eight narrow beams ", and 1-1a, 1-2a, 1-3a,
1-4a, 1-1b, 1-2b, 1-3b and 1-4b are respectively 8 narrow beams emitted respectively by 8 narrow beam antennas.In Fig. 4 A, by institute
It is the broad beam 1 emitted by broad beam antenna to have the dotted line that narrow beam is included.
The base station of cell A sends common channel information by broad beam 1 to UE.Polling cycle is divided by the base station of cell A
