Embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing to this hair
Bright each embodiment is explained in detail.However, it will be understood by those skilled in the art that
In each embodiment of the present invention, in order that reader more fully understands the application and to propose many technologies thin
Section.But even if without these ins and outs and many variations based on following embodiment and modification,
Each claim of the application technical scheme claimed can also be realized.
For " signal blind zone " existing for existing base station antenna system, i.e., so-called " black under tower " is asked
Topic.The embodiments of the invention provide a kind of new antenna for base station, its structure is referred to shown in Fig. 2.Such as
Shown in Fig. 2, the antenna for base station includes：First antenna A and the second antenna B, first antenna A and
Two antenna B are installed on same base station towers, to provide service for a range of user.Wherein, in reality
In border, first antenna A signal cover may cause the presence of signal blind zone, the signal blind zone master
It is present under base station towers, signal blind zone is referred to shown in Fig. 1.And the second antenna B is used to cover first
The antenna A signal blind zone, it is blind to first antenna A mend.
Wherein, first antenna A mainly completes the function of antenna receiving and transmitting signal, ensures that antenna normally covers model
The communication quality of terminal user (such as mobile subscriber) in enclosing, meet such as browsing webpage, seeing for user
See a variety of demands such as video.The benefit that second antenna B mainly completes signal under tower is blind, ensures that user is just under tower
Normal mobile communication demand, to solve the problems, such as " under tower black ".
Furthermore it is possible to service range (such as signal cover) interior number of users according to first antenna A
And the changes in distribution of number of users, to adjust first antenna A angle of declination α 1 and its radiant power P1.
, can be according to the change of first antenna A signal blind zone, then correspondingly after the completion of first antenna A regulations
The angle of declination α 2 and its radiant power P1 of the second antenna B wave beams are adjusted, it is blind to re-start benefit.So as to,
Can solve the problems, such as under tower that signal is weak or no signal.In addition, first antenna A and the second antenna B work(
Rate is adjustable, such as mainly will can be provided by RRU (radio remote unit, RF remote unit)
Radiant power is reasonably assigned to the region that signal is weaker under antenna normal coverage area and tower, and satisfaction is covered
The proper communication demand of all users in cover area, maximumlly utilize base station resource and antenna resources.
Separately below to first antenna A and the second antenna B adjustment of angle of declination and the adjustment of radiant power
Illustrate respectively.It should be noted that for the same antenna, adjustment to its angle of declination and it is radiated
The adjustment of power can be carried out simultaneously, i.e., while angle of declination is adjusted, adjust its radiant power.
As shown in Fig. 2 first antenna A angle of declination α 1, by adjusting angle of declination α 1, it is assumed that it is adjusted
Whole amount is Δ α 1, and to change first antenna A signal cover, wherein first antenna A signal covers
Lid scope is such as shown in (N1, N2), and wherein N1, N2 are referred to as first antenna A effective edge
Boundary.Second antenna B angle of declination α 2, by adjusting angle of declination α 2, it is assumed that its adjustment amount is Δ α 2,
To change the second antenna B signal cover, wherein the second antenna B signal cover as (G1,
G2 shown in), wherein G1, G2 are referred to as the second antenna B efficiency frontier.In general, it is
Solve the problems, such as " signal blind zone " to maximum program, second antenna B relative position can set with
First antenna A efficiency frontier overlaps, such as shown in Fig. 2 the second antenna B is first antenna A
Efficiency frontier N2 overlap.
In fig. 2, the second antenna B adjustment is premised on first antenna A.And under normal circumstances
What first antenna A efficiency frontier N1, N2 was to determine, when the angle of inclination of first antenna A main body
When (i.e. angle of declination) changes, the change of equal angular can occur for its efficiency frontier.In the present embodiment,
Following incidence relation be present in the situation of change at first antenna A and the second antenna B downwards bevel beam angle：
Δ α 2=k Δ α 1+ ε (1)
Δ α 1 is the variable quantity or adjustment amount of first antenna A angle of declination, and Δ α 2 is under the second antenna B
The variable quantity or adjustment amount at inclination angle；K is weight coefficient, and some parameters of its size and antenna itself are related；
ε is constant, and first antenna A and the second antenna B relative position is relevant during with opening station.In order to effectively
Solve " signal blind zone " problem, in formula (1), k=1, and ε=0.
Wherein, the adjustment amount Δ α 1 of first antenna A angle of declination, can be according to first antenna A signal
The changes in distribution situation of number of users in coverage determines.And work as first antenna A angle of declination
, then can be by the adjustment amount of first antenna A angle of declination, to determine second after adjustment amount Δ α 1 is determined
The adjustment amount Δ α 2 of antenna B angle of declination.
The principle of the Adjusted Option of the angle of declination of the antenna of the embodiment of the present invention is illustrated above, under
Scheme in face of the adjustment (or distribution) of the radiant power of the antenna of the embodiment of the present invention illustrates.Need
