Embodiments provide a kind of method of signal transmission, be applied to a kind of device for signal transmission, institute
State device and include manipulator, RF transceiver, power amplifier, antenna, described device also includes first and changes road device, second changes
Road device and a bypass, described first inbound port changing road device is connected to the exit port of RF transceiver, and described first changes road
First exit port of device is connected to the inbound port of power amplifier, and the second exit port is connected to the inbound port of bypass, and described second
The first inbound port changing road device is connected to the exit port of power amplifier, and the described second the second inbound port changing road device is connected to side
The exit port on road, described second exit port changing road device is connected to the inbound port of antenna.
Wherein, the first function of changing road device and the second functional realiey changing road device can be understood as two hilted broadsword devices and opens
Close, its role is within the same time period, only allow the output signal of RF transceiver via RF transceiver-power
Amplifier-antenna or antenna front ends equipment, and, RF transceiver-bypass-antenna or antenna front ends equipment two transmit roads
One in footpath is transmitted.
In addition, the effect of the bypass in the embodiment of the present invention essentially consists in offer idle or is significantly lower than power amplifier
The transmission line of power consumption, therefore, typically can simply rely on common equipment room connecting line and be transmitted, or other in order to
Matching unit impedance and realized using other idle elements.
The method of signal transmission provided in an embodiment of the present invention is it is adaptable to any equipment with aforementioned items components and parts
In, such as smart mobile phone, panel computer etc..
The flow process of the method is as shown in Fig. 2 include：
101st, when aforementioned power amplifier is in running order, described manipulator obtains the current signal of described antenna and sends out
Penetrate the magnitude relationship between maximum transmission power when power and line zero power amplifier.
Wherein, the current signal transmission power of described antenna refers to that equipment sends to equipment such as base station, mobile access points
The transmission power using during row signal.And maximum transmission power during line zero power amplifier refers to that equipment carries out zero in power amplifier
The maximum transmission power that can reach during gain.
102nd, when the current signal transmission power of described antenna be not more than line zero power amplifier when maximum transmission power when, institute
State manipulator and change road device by controlling described first to change road device and second, current demand signal transmission path is put by through described power
Big device is adjusted to through described bypass, controls described power amplifier to quit work simultaneously.
Because first changes road device and second and change road utensil and have the function of similar switch, therefore, manipulator only needs to two
Change road device and send control signal and can trigger Liang Gehuan road device and the line conduction situation of respective inside is switched over.
103rd, described manipulator adjusts the transmission power of described RF transceiver, to maintain the current signal of described antenna
Transmission power is constant.
It should be noted that due to needing to stop the work of power amplifier, the now transmission power of RF transceiver
No longer receive the gain of power amplifier, then the signal being input to antenna will certainly diminish, accordingly, it would be desirable to adjustment RF signal receiving and s ending
The transmission power of machine is to ensure to remain able to reach the current signal transmitting work(of antenna after the loss of each components and parts
Rate.
For example, the peak power output of RF transceiver (Transceiver) is 3dB, and front end Insertion Loss is probably
4dB, along with the Insertion Loss 1dB of two switches.At this moment antenna signal in the case of not accepting any power amplifier gain is sent out
Penetrate power maximum and can reach -2dB.If now the output of current radio frequency transceiver is -1dB, power amplifier (PA) increases
Benefit probably can be in 5dB, then the signal transmission power of current antenna is -3dB, less than emission maximum work(during line zero power amplifier
Rate -2dB.For technical scheme provided in an embodiment of the present invention, now need to close power amplifier (PA), also just reduce
The power amplification gain of 5dB, then the current transmission power of RF transceiver needs to adjust to peak power output 3dB,
The current signal transmission power of described antenna thus can be maintained constant.
The method of the signal transmission that the embodiment of the present invention is provided, the signal transmission power current by judging described antenna
Magnitude relationship and maximum transmission power during line zero power amplifier between, to determine RF transceiver when in its own transmission work(
Rate can meet current antenna signal transmission power (i.e. current uplink and downlink communication quality is good), when determination RF transceiver exists
When its own transmission power can meet current antenna signal transmission power, rely on newly-increased changing produced by road device and bypass newly
Transmission path to replace original transmission path needing through power amplifier, thus can stop the work of power amplifier
Make, be changed into the Working mould of " only RF transceiver " from the mode of operation of original " power amplifier+RF transceiver "
Formula.Because the quit work electricity that brings of power amplifier is saved and is significantly larger than RF transceiver and provides transmission power to be consumed
Electricity, therefore, in the case of current uplink and downlink communication is the second best in quality, can effectively save the power consumption of equipment, extend and use
Time.

It is fed to described manipulator.
In the method, this structural modulation device is relied on can accurately to know the current signal transmission signal of antenna, compared to
First method, more objective and accurate.
In addition, obtaining the current signal transmission power of described antenna and circuit zero power in manipulator described in execution step 101
After the magnitude relationship between maximum transmission power when putting, when the current signal transmission power of described antenna is more than circuit zero power
During maximum transmission power when putting, then current device is maintained to work constant, i.e. execution step 104, as shown in fig. 6, this step bag
Include：
104th, described first is maintained to change the working condition that road device and described second changes road device, and, maintain described radio frequency to receive

In addition, if uplink and downlink communication quality runs down so that the transmission power of RF transceiver is not enough to carry
During for enough transmission powers, then need to restart power amplifier, related method flow is as shown in fig. 7, also include：
401st, when the pre- transmission power of aerial signal be more than line zero power amplifier when maximum transmission power when, described manipulator lead to
Cross and control described first to change road device and second to change road device, current demand signal transmission path is adjusted to through institute by through described bypass
State power amplifier, control described power amplifier to start working simultaneously.
Wherein, the pre- transmission power of aerial signal can rely on the symmetrical principle of up-downgoing channel quality in communication system, leads to
Cross the detection to down receiving signal power, to infer the transmission power needed for upward signal.
402nd, the described manipulator adjustment transmission power of described RF transceiver and the gain of described power amplifier
