Since the increase of the transmission power may not help the signal enhancement at all, and a good received signal and a good transmitted signal must be used together, the signal quality analysis module 53 may first analyze the received signal to determine the signal quality, determine whether the signal strength is higher than a set threshold, and ensure the received signal quality, and meanwhile, when the transmission power is increased, the excessive power may cause interference between cells, so that the power needs to be corrected in real time according to an instruction issued by the network, and the signal strength analysis module 51 and the power correction module form a closed loop. The circuit control module 54 is configured to determine whether to enable the power boosting module according to a conclusion obtained from the analysis results of the signal strength determining module 51, the transmission power analyzing module 52, and the signal quality analyzing module 53, and the circuit control module 54 performs circuit control, where the control circuit switches between a default circuit and enabling the power boosting module. The rf power amplifier module 55 includes two power amplifiers, and besides the two PA stages, the rf circuit further includes corresponding filters, switches, and adaptive attenuation modules. The first function of the self-adaptive attenuation module is to avoid saturation of two stages of power amplifiers, and the second function is to ensure impedance matching between two PAs. Based on the method, the two cascaded power amplifiers are matched with each other to play a role in enhancing power, and are responsible for transmitting radio frequency power with high efficiency and high quality to realize high-quality network communication.
Fig. 7 is a schematic structural diagram of a transmission power enhancement device according to an embodiment of the present application, and referring to fig. 7, the transmission power enhancement device may include a main power amplifier Default PA60, an auxiliary power amplifier PA61, a radio frequency switch 62, an adaptive attenuation module 63, and an antenna 64, where the two PAs are connected by using the radio frequency switch 62, and when the radio frequency switch 62 is closed, the main PA60 and the auxiliary PA61 form a cascade to enable the power enhancement PA. An adaptive attenuation module 63 is further connected between the main PA60 and the auxiliary PA61, and the antenna 64 can transmit signals enhanced by the main PA60 and the auxiliary PA61 when the radio frequency switch is closed, and the antenna 64 can also transmit signals enhanced by the main PA60 when the radio frequency switch 62 is opened.
Exemplarily, fig. 8 is a schematic structural diagram of a mobile terminal provided in an embodiment of the present application, and referring to fig. 8, the mobile terminal includes: the device comprises a signal monitoring module L1, a transmission power analysis module L2, a circuit control module L3, a radio frequency power amplifier module L4 and a parameter storage unit L5. The L1 signal monitoring module is connected with the transmission power analysis module L2 and is used for detecting the network environment of the mobile terminal. The network environment may include network parameter indexes such as a working frequency band, a frequency point, a wireless Signal strength, a Signal-to-Noise Ratio (SNR), uplink and downlink call quality, a data throughput rate, and a bit error rate. The L1 signal monitoring module works as follows, the antenna receives a communication signal from a base station, the communication signal is filtered and amplified by a radio frequency front end device and transmitted to a baseband processing chip, the baseband chip demodulates the signal to obtain corresponding network parameters, such as network type (e.g. GSM/WCDMA/CDMA/LTE/NR, etc.), cell information (e.g. Cell info, PCI, etc.), frequency band (e.g. B1/B3/N78/N41, etc.), channel number (Arfcn) or center frequency point, and also signal quality parameters, such as signal strength (e.g. RSSI, RSRP), signal to noise ratio (SNR), etc., and through these parameters, the real-time strength and quality of the terminal network signal can be obtained, so as to perform corresponding power related processing. The signal monitoring module has two main functions, one is to monitor the signal intensity of the mobile terminal, when the signal intensity of the mobile terminal is weaker, the power enhancement operation is enabled, the second is to monitor the quality of uplink and downlink signals of the mobile terminal, firstly, when the quality of the downlink signals meets the requirements, the power is increased to optimize and improve the communication quality, but the power cannot be improved at one step, and the quality of the uplink signals is also ensured, so the module can also monitor uplink indexes such as bit error rate, throughput rate and the like in real time, when the uplink indexes do not meet the standards, the power is not increased any more, necessary power backspacing can be performed, and the whole power enhancement module is more flexible. For example, if the mobile terminal has a weak signal strength and RSRP is lower than-120 dBm, which indicates that the signal strength and quality are weak, in order to improve the communication quality, the module is enabled to improve the transmission power, the module also monitors the downlink network quality in real time through indexes such as SNR, and when the SNR index is smaller than 10, which indicates that the downlink signal quality of the mobile terminal cannot meet the requirement, the power increase is stopped; meanwhile, when the uplink indexes such as the bit error rate and the throughput rate are monitored to be not up to the standard, the power increase is stopped.
The transmission power analysis module L2 is connected with the circuit control module L3, a specific transmission power value is obtained according to a control instruction (such as PUSCH and PUCCH) issued by a base station, an optimal radio frequency transmission scheme is selected according to the power value, when the power is smaller than the maximum calibration power under the condition of a single power amplifier module calibrated in advance, only a default single power amplifier module is used, another enhanced power amplifier is not started, when the power is larger than the maximum calibration power under the condition of the single power amplifier module, the single power amplifier module is saturated, the power requirement of a terminal cannot be met, at the moment, a second enhanced power amplifier unit in the power enhanced module needs to be activated, a double power amplifier strategy is implemented, and the power is improved to a greater extent. The invention adopts a step-by-step power increasing scheme, firstly judges whether the current power is larger than the maximum calibrating power of a single power amplifier module, if not, the power is gradually increased by taking 1 as step, before the power is increased each time, the signal analysis module L1 analyzes the quality of uplink and downlink signals in real time, and the power can be continuously increased only when the signal quality reaches the standard. For example, when the current transmission power is 22dBm, the weak signal is small, the SNR of the downlink signal is greater than 15, the requirement is met, the power is increased upwards by 1dBm, and when the SNR is less than 15, the power enhancement operation is not performed. When the power is less than 25dBm, the default single amplifying circuit is still adopted to work, when the power is increased to be more than 25dBm, the enhancement module starts to work simultaneously, 1dBm is still used for increasing upwards, and on the premise that the quality of uplink and downlink signals reaches the standard and the power does not exceed the maximum power limit Pmax of the system, the signal strength reaches the standard.
And the circuit control module L3 is connected with the radio frequency power amplifier module L4, and controls the radio frequency circuit according to the information obtained by the L1 module and the L2 module, wherein the control content comprises a frequency band, a channel, a power amplification scheme and a transmitting power value.
The radio frequency power amplifier module L4 is used for transmitting radio frequency power, a power enhancing module is newly added on the basis of an original power amplifying circuit, besides the two-stage amplifying circuit, the radio frequency circuit also comprises a corresponding filter, a switch and a self-adaptive attenuation module, the attenuation module has the first function of avoiding the saturation of the two-stage power amplifiers, and the second function of ensuring the impedance matching between the two power amplifiers. Based on this, the newly-added power amplifier and the original power amplifier are mutually matched to play a role in enhancing the power, and are responsible for efficiently transmitting the radio frequency power with high quality, so that high-quality network communication is realized. The signal quality analysis module L3 is connected to the transmission power analysis module L2, and is configured to determine whether the increase of the uplink power actually improves the network signal quality. Under the condition that some uplink and downlink signals are weak, the transmission power is increased at one step, which is not necessarily beneficial to signal improvement, but the excessive power may cause index degradation and cause interference between cells, so that the quality of the received signals must be analyzed, and the power can be increased only when the quality of the received signals is greater than a preset value.
And the parameter storage module L5 is connected with the circuit control module L4 and is used for storing various calibration parameters and control parameters. And meanwhile, the method is also used for controlling the storage of the starting and closing parameters of the subsequent unit modules.
