Wherein, each signal is provided with specific standard and special frequency channel, correspondingly, can be propped up according to each root antenna
The standard and frequency range held can be a kind of signal with specific standard and special frequency channel of each root antenna assignment.Specifically,
Each signal can be sent and received respectively by the interface of each root antenna.
It is worth noting that although same root sub-antenna is only used for sending and receiving one kind and has specific standard and specific
The signal of frequency range, but be different sub-antenna and can send and receive same signal simultaneously, i.e., same signal can lead to
An excessive sub-antenna sends and receives.For example, as shown in figure 3, two root antennas 31 can be used to send and receive simultaneously LTE letter
Number, to utilize multiple-input and multiple-output (Multiple Input Multiple Output, MIMO) technology, enhance the logical of base station
Believe capacity and covering power.
Step 504, the sub-antenna by distributing for each signal, send each signal.
The embodiment of the present invention by obtain frequency range in the signal to be sent of base station and coding mode identify have it is specific
Each of standard and special frequency channel signal distribute sub-antenna for each signal, and send and connect by the sub-antenna of distribution
Each signal is received, to complete the signal covering of base station.Wherein, each root antenna only sends a kind of signal, and each
The angle of declination of sub-antenna can be adjusted independently, therefore, when adjustment sends and receives each root antenna of a certain signal
Angle of declination when coverage area to change the signal, will not change the coverage area of other signals, so as to so that each is believed
Number coverage area can adjust separately and be optimal, improve the covering power and message capacity of base station.
As shown in fig. 6, can be applied to the embodiment of the invention also provides the method for another adjustment Downtilt
State base station, which includes antenna, and antenna includes at least two root antennas, wherein a root antenna, be served only for same standard and
The signal of same frequency range sends and receives.This method specifically includes:
Step 601, according to the second specified signal, obtain the wireless resource utility efficiency of the second specified sub-antenna.
Wherein, the second specified signal is the signal that base station is sent by the second specified sub-antenna, and second specifies sub- day
