Description
Technical field
The present invention relates to the antenna-feed parameter optimization method of electronic technology field more particularly to a kind of shared antenna antenna-feeder system and
Device.
Background technology
In the construction and Optimization Work of current TD-LTE, we are faced with the continuous improvement of complicated network structure degree, wirelessly
The fact that resource day is becoming tight.In the environment of residential block is increasingly intensive, user is to radiation effect growing interest, macrocellular network
Deployment by increasing resistance, site and terrace resource also tend to be nervous, under this kind of background, the application one of shared antenna
Determine to alleviate this contradiction in degree, TD-SCDMA refers to closing the signal of TD-SCDMA and TD-LTE with TD-LTE shared antennas
Emit by same surface antenna behind road.It can make not increase antenna amount, two systems when building using shared antenna scheme
Common antenna.
When building TD-LTE networks, using TD-SCDMA and TD-LTE shared antenna modes, combining antenna is introduced, is simplified
Construction process reduces quantities and lower deployment cost.
But there is also some drawbacks, are especially embodied in complexity, the covering power difference aspect of overall network optimization.It is first
First, when TD-SCDMA is with TD-LTE shared antennas, the common parameters such as deflection, angle of declination of antenna are consistent, but two kinds of network formats
Optimization and covering index and demand it is all different, existed using frequency range additionally, due to TD-SCDMA and TD-LTE Network Dept.s
Difference, such as：TD-LTE uses D frequency range networking, TD-SCDMA to penetrate damage because frequency range interval is larger using A frequency ranges or F-band
Consume it is variant, then under the conditions of shared antenna, the network coverage radius of TD-LTE with the network coverage half of site TD-SCDMA network
Diameter is different, and challenge is proposed to later stage optimization.
When antenna height is 40 meters, from when being adjusted to 5 degree for 0 degree, the influence to TD-SCDMA network may be angle of declination：Have
Effect covering radius be contracted to from 500 meters 420 meters, cell average signal strength RSCP be promoted to -80dBm from -85dBm, overlapping is covered
Cover degree 0.3 is down to 0.2, and average carrier/interface ratio (C/I) is promoted to 15dB from 12dB.To the TD-LTE cells of total antenna feeder, 5 degree have a down dip
Angle can promote cell SINR indexs, and 13dB is increased to from 10dB, due to TD-LTE downloading rate in a certain range with SINR
Index has stronger positive correlation, when bottom make an uproar it is constant in the case of, the average download rate of LTE cells is about promoted to from 28M/s
35M/s, covering radius are reduced to 350 meters from 400 meters, remain able to meet covering demand.But if Downtilt adjusts
To 10 degree, it is possible that result be：The covering radius of TD-LTE is reduced to 300 meters, still can meet covering for the cell
Lid demand；But the covering radius of TD-SCDMA is reduced to 350 meters, since TD-SCDMA network average headway is 400 meters, leads
Covering cavity is caused to occur, cell indices deteriorate.
For current TD-SCDMA and TD-LTE shared antennas antenna-feeder system, for the influence of complexity, covering power difference
Caused by cover cavity and occur, the problems such as cell property indices deteriorate, there is presently no to TD-SCDMA and TD-
The antenna parameter of LTE shared antenna antenna-feeder systems optimizes method.
