Abstract
The present invention relates to communications field intelligent control technology, more particularly to wireless communication system by radius of society tuning, reduce interference, increase covering, lifting portfolio and client perception for the purpose of control, judgement and method.In wireless communication technology of the ZC sequences as random access lead code is used, the cyclic shift of ZC root sequences is often also used as different lead codes, the length NCS of cyclic shift is related to radius of society, under scale commercial network, each cell employs fixed NCS as expected, for surpass the expectation covering radius in the case of do not find then with tuning adaptation mechanism, it is have signal but cannot do business that user perceives under such scene.The present invention seeks to overcome problem above, the technical solution adopted by the present invention is that base station judges whether that the cell setting actual covering radius of radius ratio is small by increasing Stochastic accessing observation window, and detection is recorded by response window and observation window（Itself）Cell root sequence delay positions determine whether the setting actual covering radius of radius is reasonable.
Description
Technical field
The present invention relates to communications field intelligent control technology, more particularly to wireless communication system by radius of society tuning, reduce interference, increase covering, lifting portfolio and client perception for the purpose of control, judgement and method.
Background technology
In wireless communication technology of the ZC sequences as random access lead code is used, the cyclic shift of ZC root sequences is often also used as different lead codes, the length NCS of cyclic shift is related to radius of society, NCS is bigger, the radius of society of support is bigger, in the case where every cell is certain using leading number of codes, the root sequence that respective cell to be used is also more, because of root sequence limited amount, minizone root sequence produces the probability of repeated collision to be increased by, needs carry out balance, and LTE and follow-up evolution are exactly situation so.Under scale commercial network, each cell employs fixed NCS as expected, for surpass the expectation covering radius in the case of do not find then with tuning adaptation mechanism, it is have signal but cannot do business that user perceives under such scene.
The content of the invention
For problem above, the solution that the present invention is used is：Having ensured that each cell root Sequence Planning is correct, after multiplex distance is more than setting radius of society and as far as possible big, response window is opened in base station by the former NCS1 that sets, and observation window is opened by bigger NCS2 on the basis of response window, and observation window size is（NCS2-NCS1）, in response window detect Stochastic accessing, by normal process and record detection position, in observation window detect Stochastic accessing, judge that whether which ZC roots sequence is the lead code belong to or belong to either own cell root sequence, record root sequence information with detection position.According to the statistics of some durations（It is reliability, duration is unsuitable too short, should be with hour as least unit）If the number of times that observation window detection root sequence belongs to this cell root sequence is more than thresholding L（Parameter nomenclature, it is fixed by actually taking by operator）The root sequence for then belonging to this cell by detection determines NCS3 in the maximum delay position of observation window, NCS3 on probation replaces NCS1, and avoid being overlapped with this cell root sequence by the Stochastic accessing root sequence setting of surrounding co-frequency cell is replaced more than the inspection of NCS3 respective radius, observation window is opened with the NCS4 bigger than NCS3, flow before repeating, is not less than the actual covering radius of cell, is reasonable value until confirmation radius of society is set.It is small for actual covering radius, but NCS1 sets excessive, it should be seen that maximum delay detection position only has the X% of NCS1 in response window（Parameter nomenclature, it is fixed by actually taking by operator）And observation window is without either own cell root sequence detection, then NCS5 is set using foregoing actual maximum detection position, NCS5 on probation replaces NCS1, and avoid being overlapped with this cell root sequence with the setting of frequency LTE cell Stochastic accessing roots sequence by surrounding is replaced more than the inspection of NCS5 respective radius, observation window is opened with the NCS6 bigger than NCS5, flow before repeating is reasonable value until confirming that radius of society is set not too much more than the actual covering radius of cell.Determine reasonable NCS by actual covering（Radius of society）Benefit be to fully absorb business, reduction has signal but can not do the situation of business, and rationally consumes root sequence resources, reduces short distance multiplexing conflict.
Abbreviation explanation：ZC --- Zadoff-Chu sequence；Press NCS setting windowings and receive detection Stochastic accessing in NCS --- cyclic shift length, respective cell radius, base station.
