Description
Technical Field
The present application relates to the field of communications technologies, and in particular, to a method and an apparatus for amplifying a wireless signal.
Background
With the continuous development of Communication technology, a Narrow-Band Internet of Things (NB-IoT) based on cellular comes to be developed, and to reduce the deployment cost, the NB-IoT network is directly deployed in a Global System for Mobile Communication (GSM) network and shares the same frequency Band with the GSM network, where the frequency Band indicates that the frequency of signals is within a range, the frequency bandwidth of GSM signals is 200KHZ, and the frequency bandwidth of NB-IoT signals is 3.75KHZ and 15 KHZ.
In general, in order to expand the signal coverage of the macro base station and improve the communication quality, operators generally deploy a large number of wireless signal amplification devices in a GSM network to amplify wireless signals. In the middle of the period, the wireless signal amplifying device usually adopts a wireless repeater, including a broadband repeater and a frequency-selecting repeater.
In the prior art, when a wireless signal amplification device amplifies a wireless signal including a GSM signal and an NB-IoT signal, the following methods are mainly adopted:
the first mode is as follows: the received wireless signals of all frequency bands are amplified to set power through the broadband repeater, namely the amplified power of the wireless signals of all frequency bands is the set power.
However, in this way, since the GSM signal and the NB-IoT signal are amplified to the same set power, and the bandwidth difference between the GSM signal and the NB-IoT signal is large, the power spectral densities of the GSM signal and the NB-IoT signal obtained by the ratio of the set power to the bandwidth are large, which may increase the loss of devices of each device in the network system, reduce the system capacity of the NB-IoT signal, and reduce the success rate of communication services.
The second way is: the frequency-selecting repeater adopts a wireless signal demodulation mode, determines a wireless signal of a set frequency band in all received wireless signals, and amplifies the wireless signal of the set frequency band according to set power.
However, in this way, since the wireless signals in the set frequency band are all amplified to the same set power, when the GSM signal and/or the NB-IoT signal are amplified, the GSM signal and the NB-IoT signal cannot be amplified according to different amplification factors, and since the GSM signal and the NB-IoT signal both have corresponding amplification requirements, only one of the GSM signal and the NB-IoT signal is amplified, and the requirement for signal amplification cannot be met.
Further, the GSM signal and the NB-IoT signal included in the wireless signal are analyzed in a wireless signal demodulation manner, which is relatively high in cost.

Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present application without any creative effort belong to the protection scope of the present application.
In order to reduce the cost of amplifying wireless signals, amplify different times aiming at different types of wireless signals and improve the success rate of communication services, in the embodiment of the application, a wireless signal amplifying method is designed, the method comprises analyzing the bandwidth of a received wireless signal to obtain a first signal power of a first signal with a bandwidth of a first predetermined bandwidth value, and a second signal power of a second signal having a bandwidth of a second predetermined bandwidth, and calculating a signal power ratio of the first signal power and the second signal power, and performing power allocation for the first signal and the second signal based on the signal power ratio, and further, based on the maximum amplification factor and the maximum power value, and adjusting the distributed first output power and second output power, amplifying the first signal power to the adjusted first output power, and amplifying the second signal power to the adjusted second output power.
The preferred embodiments of the present application will be described below with reference to the accompanying drawings of the specification, it being understood that the preferred embodiments described herein are merely for illustrating and explaining the present invention and are not intended to limit the present invention, and that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
Referring to fig. 1, which is a flowchart illustrating an amplification process of a wireless signal, in the embodiment of the present application, the method is mainly applied to a wireless signal amplification device, and a specific process of amplifying the wireless signal is as follows:
step 100: the terminal analyzes the frequency width of the received wireless signal, and determines a first signal with the frequency width of a first preset frequency width value and a second signal with the frequency width of a second preset frequency width value.
Specifically, the terminal receives a wireless signal sent by the signal transmitting device, performs bandwidth analysis on the wireless signal, and determines a first signal and a second signal included in the wireless signal.
Optionally, the terminal may be a wireless signal amplifying device, the signal transmitting device may be a base station or an intelligent terminal, and the first signal and the second signal may be any two of a GSM signal, an NB-IoT signal, and a Long Term Evolution (LTE) signal.
Since the bandwidth of each signal is different, for example, the bandwidth of the GSM signal is 200KHZ, and the bandwidth of the NB-IoT signal is 3.75KHZ and 15KHZ, the wireless signal can be analyzed through the bandwidth to determine various types of signals.
Optionally, the first signal is set to be a GSM signal, the first preset bandwidth value is 200KHZ, the second signal is set to be an NB-IoT signal, and the second preset bandwidth value is 50 KHZ.
The second preset bandwidth value is set to 50KHZ, so that the detection precision of the terminal in bandwidth analysis can be reduced, and the detection cost is reduced.
Therefore, various signals can be distinguished through frequency width, the problem that in the prior art, the cost is high when various signals are distinguished through a wireless signal demodulation mode is solved, and the cost of wireless signal analysis is reduced.
Step 101: the terminal obtains a first signal power of the first signal and a second signal power of the second signal, calculates a ratio of the first signal power and the second signal power, and obtains a signal power ratio.
Step 102: and the terminal performs power distribution on the preset total power based on the acquired signal power ratio, and determines first output power distributed to the first signal and second output power distributed to the second signal.
Specifically, when step 102 is executed, the following method may be adopted:
the first mode is as follows: and when the terminal determines that the signal power ratio is not lower than the first preset ratio, the terminal performs power distribution on the total power according to a preset power distribution ratio to obtain first output power and second output power.
For example, the terminal sets the first preset ratio to 10, the power distribution ratio to 10, the total power to 11W, calculates the signal power ratio of the GSM signal (first signal) to the NB-IoT signal (second signal) to be 1:0.1 to 10, and then, according to 10: 1, distributing the total power 11W to obtain a first output power of 10W and a second output power of 1W.
The second way is: and when the terminal determines that the signal power ratio is lower than the first preset ratio and higher than the second preset ratio, calculating the product of the first signal power and the preset multiple and taking the product as the first output power, and calculating the product of the second signal power and the preset amplification factor and taking the product as the second output power.
For example, the terminal sets the first preset ratio to 10, the second preset ratio to 1, the preset amplification factor to 5, calculates the signal power ratio of the GSM signal (the first signal) to the NB-IoT signal (the second signal) to be 2:1 to 2, and determines that 2 is within [1, 10], then amplifies the power of both the GSM signal (the first signal) and the NB-IoT signal (the second signal) by 5 times, that is, the first output power is 2 to 5 to 10W, and the second output power is 1 to 5W.
The third mode is as follows: and when the terminal determines that the signal power ratio is not higher than a second preset ratio, calculating the product of the preset maximum amplification factor and the second signal power, taking the product as second output power, calculating the difference value between the total power and the second output power, and taking the difference value as first output power.
For example, the terminal sets the second preset ratio to 1, the total power to 20W, the maximum amplification factor to 10, calculates the signal power ratio of the GSM signal (the first signal) to the NB-IoT signal (the second signal) to be 1:5 to 0.2, and determines that 0.2 is less than 1, then determines that the second output power is 1 to 10W, and the first output power is 20 to 10W.
Alternatively, the first predetermined ratio may be 10, the second predetermined ratio may be 1, the total power may be 20W, and the maximum amplification factor may be 10.
The total power can be adjusted correspondingly according to the magnitudes of the first signal power and the second signal power, so that when the first signal power and the second signal power are smaller, a larger total power can be adopted to supplement the signals, and otherwise, a smaller total power is selected.
Step 103: and the terminal preliminarily adjusts the obtained first output power and the second output power based on a preset maximum amplification factor.
Specifically, first, the terminal calculates an amplification ratio of the second output power to the second signal power.
Then, when the terminal determines that the obtained amplification ratio is higher than the maximum amplification, the terminal calculates a product of the maximum amplification and the second signal power, adjusts the second output power to the product, calculates a difference between the total power and the adjusted second output power, and adjusts the second output power to the difference.
Further, if the obtained amplification factor is not higher than the maximum amplification factor, the terminal does not adjust the first output power and the second output power.
Therefore, the power amplification factor of the signal can be limited, and the condition of overlarge amplification factor is avoided.
Step 104: and the terminal readjusts the acquired first output power and the second output power based on the preset maximum power value.
Specifically, first, the terminal determines whether the received wireless signal is an uplink transmission signal, if so, sets the maximum power value to a preset maximum uplink power value, otherwise, sets the maximum power value to a preset maximum downlink power value.
Optionally, the maximum uplink power value may be 1W, and the maximum downlink power value may be 10W.
Thus, the maximum power value of the amplified wireless signal can be adjusted according to the uplink transmission signal and the downlink transmission signal.
Then, when the terminal determines that the obtained second output power is higher than the maximum power value, the terminal adjusts the second output power to the maximum power value.
And finally, the terminal calculates the difference between the total power and the maximum power value and adjusts the acquired first output power into the difference.
Therefore, the maximum value of the power of the amplified wireless signal can be limited, and the problems that the power of the signal is too large, loss is caused to devices and the success rate of communication service is reduced are solved.
Step 105: the terminal amplifies the first signal power to the adjusted first output power and amplifies the second signal power to the adjusted second output power.
Therefore, the first signal and the second signal can be distinguished by analyzing the frequency width of the wireless signal, the cost of signal analysis is reduced, the efficiency of signal analysis is improved, furthermore, corresponding power is distributed for the first signal and the second signal according to the signal power ratio of the first signal power and the second signal power, the power value after amplification is limited through the maximum amplification factor and the maximum power value, and different amplification of different signals is realized.
