Description
Technical field
The present embodiments relate to network communication technology field more particularly to a kind of interference suitable for sectorization identical networking
Signal coordination methodology and device.
Background technique
In current communication system, according to different network construction forms, being divided into identical networking, (the re-used across cells factor is
1), inter-frequency networking (the re-used across cells factor is 3 or more)；Under inter-frequency networking, using different between different neighboring communities
Frequency band will not generate inter-cell interference, or inter-cell interference (the interference letter from non-adjacent farther cell of only very little
Number), but a disadvantage is that each cell available bandwidth becomes 1/3 or 1/N of whole system available bandwidth, generally speaking, although dry
The mode for disturbing inhibition is simpler, but entire throughput also suffers from influence；And identical networking, it can make between neighboring community
With whole system bandwidths, band efficiency is much higher than inter-frequency networking, but inter-cell interference, which can become, influences entire throughput
Key factor；Especially in the cellular radio Communication system based on orthogonal frequency division multiplexi (OFDM), intra-cell users are logical
It crosses frequency division multiplexing and realizes the orthogonal of signal, to solve the problems, such as intra-cell interference.But as cost, identical networking can bring compared with
Strong inter-cell interference.Meanwhile Cell Edge User uses biggish transmission power, generates to the edge customer of adjacent cell very strong
Interference, seriously affect marginal user performance.
In identical networking, omnidirectional can be further divided into frequency such as omnidirectional antenna and directional aerial according to different antenna configurations
Cell networking and sectorization identical networking；In urban area circumstance, in order to increase capacity in wireless communication system, often introduce
Sectorization directional aerial can obtain higher antenna gain in this way, that is, can increase coverage distance, and can improve cell capacity, i.e.,
Multiple sectors are divided under each base station (eNodeB), respectively has a set of independent running time-frequency resource, is pressed down by the directive gain of antenna
System is the same as the interference between the sector of location.And in order to guarantee continuously to cover, sector intersection still has certain antenna gain, identical in this way
The interference between multiple sectors under base station cannot be effectively suppressed.
In the interference of co-located cell, the sector-edge user of co-located neighboring community is in cell if closer from base station
Center, then it is also larger to the co-located interference of adjacent co-located cell, especially to the Cell Edge User of adjacent co-located cell
Maximum is influenced, because path loss is much smaller than decaying of the directional aerial to signal to the decline of signal at this time；If closer from base station, place
In sector intersection, then its, cell edge in addition to can interfere with adjacent co-located cell larger to the interference of adjacent co-located cell
User can also interfere with the sector-edge user of sector intersection in adjacent co-located cell.Finally, the sector of co-located neighboring community
Edge customer, if farther out from base station, it is both sector-edge user and Cell Edge User, to co-located adjacent cell
Cell Edge User interference it is larger, while to the Cell Edge User of non-co-located adjacent cell interfere it is also larger.
