[0058] At present, the existing base station antenna 110 cannot support enhanced control of the base station antenna 110, for example, cannot adjust the beam pointing of the base station antenna 110 according to the signal strength information of the radio frequency signal. In view of this, the present application provides a base station antenna which can support enhanced control of the base station antenna. Please refer to FIG. 2.

[0059] FIG. 2 is a structural schematic diagram of a base station antenna 200 according to an embodiment of the present application. As shown in FIG. 2, the base station antenna 200 includes an antenna unit 210 and a signal processing unit 220. The antenna unit 210 and the signal processing unit 220 are connected, and the connection manner is not limited, for example, the antenna unit 210 and the signal processing unit 220 can be connected by a cable or a feeder, and the like, which is not limited thereto.

[0060] Generally, a base station antenna includes a structure of an array of radiating elements, a phase shifter, and a feed network. The connection relationship between the antenna element 210 in the base station antenna 200 and the existing array of radiating elements, phase shifter, and feed network is not limited, for example, the antenna element 210 can be connected with the phase shifter or the array of radiating elements. Similarly, the connection relationship between the signal processing unit 220 in the base station antenna 200 and the existing array of radiating elements, phase shifter, and feed network is not limited, for example, the signal processing unit 220 can be connected with the phase shifter or the array of radiating elements.

[0061] The antenna element 210 can be used to collect radio frequency signals and send the radio frequency signals collected to the signal processing unit 220. The signal processing unit 220 can perform signal processing on the radio frequency signals from the antenna element 210 and output the air interface information included in the radio frequency signals. For example, the air interface information included in the radio frequency signals includes but is not limited to: frequency band information, bandwidth information, operator information, reference signal received power, reference signal received quality, channel error rate, port phase information, clock synchronization information, or cell information, etc. Wherein, the signal processing unit 220 can also send the air interface information included in the radio frequency signals to the network management 140 through wired transmission or wireless transmission, which can support the network management 140 to further manage the base station antenna 200 according to the air interface information included in the radio frequency signals.

[0062] For example, the network management 140 can adjust the pointing of the beam according to the reference signal received quality or the cell information in the air interface information included in the radio frequency signals. For another example, the network management 140 can monitor and manage the running state (such as the power and spectrum state of the radio frequency channel) of the base station antenna 200 according to the air interface information included in the radio frequency signals.

[0063] In some embodiments, the antenna element 210 and the signal processing unit 220 can be integrated or independently deployed, which is not limited.

[0064] In the embodiments of the present application, the specific deployment position of the antenna element 210 and the signal processing unit 220 is not limited. For example, the antenna element 210 can be deployed near the position of the radiating element, or the antenna element 210 can be deployed near the position of the reflector plate. For another example, the signal processing unit 220 can be deployed near the position of the feed network, or the signal processing unit 220 can also be deployed near the position of the radiating element, etc., which is not limited.

[0065] In some embodiments, the signal processing unit 220 includes, but is not limited to, one or more devices such as a baseband chip, a memory, a power amplifier device, or a radio frequency front end, and the like.

The receiving antenna 1 corresponds to a frequency band 1, the receiving antenna 2 corresponds to a frequency band 2, and the receiving antenna 3 corresponds to a frequency band 3. When the frequency band 1 is different from the frequency band 2 and the frequency band 3, and the frequency band 2 is different from the frequency band 3, this can support that the antenna unit 210 can collect radio frequency signals of different frequency bands. When the frequency band 1, the frequency band 2, and the frequency band 3 are the same, this can support that the antenna unit 210 can collect multiple radio frequency signals of the same frequency band, thereby being able to improve the collection quality of the radio frequency signals.

[0069] In some embodiments, the base station antenna 200 can further include a control switch unit 230, and the antenna unit 210 is connected with the control switch unit 230, or the control switch unit 230 is connected with the receiving antenna 1, the receiving antenna 2, and the receiving antenna 3 described above, respectively.
