Output.2nd LNA 133 is the CMOS LNA that NF is big and power attenuation is relatively small.
First processor 110 than the second processor 130 closer to antenna 105, since it is desired that
First processor 110 amplifies more weak signal.Correspondingly, place with by first processor 110
Become distance antenna 105 farther and the second switch 131 still situation in its path is compared, by the
One processor 110 is positioned to the signal from antenna 105 to be made to arrive the closer to antenna 105
During one LNA 113, deterioration is less.LNA 113 can be discussed as the most more connecing than LNA 133
Closely antenna 105, and LNA 133 can be discussed as than LNA 113 at electrically distance antenna 105
Farther.
It is each that controller 150 operates in first processor 110 and the second processor 130, and
Operation inspection according to each processor receives state.This will say in more detail with reference to Fig. 2
Bright.Controller 150 operation based on the second processor 130, according to relevant with the state of reception
Value, it is determined whether at numerical portion decision-making time operation first processor 110 and the second processor
130.The determination of numerical portion decision-making time can periodically or be carried out in the way of event triggering.
Such as, if semi-persistent scheduling (SPS) is used as audio call by terminal, then numerical portion is certainly
Plan can periodically be carried out；And if terminal request data, services, then numerical portion decision-making is permissible
The mode that event triggers is carried out.
Specifically, every in operable first and second processors 110 and 130 of controller 150
Individual, and can be based on the operation of the second processor 130, according to the value relevant with the state of reception, really
Determine whether operate the first and second processors 110 and 130 in the numerical portion decision-making time, such as Fig. 2
Shown in.Owing to first processor 110 and the second processor 130 being respectively provided with the first switch 111
With second switch 131, so controller 150 is alternatively used for using a LNA 113 and
In 4 kinds of combinations of two LNA 133 one.Signal for from antenna 105: 1)
Both LNA 113 and the 2nd LNA 133 are walked around in little gain；2) low gain
Walk around a LNA 113 and amplified by the 2nd LNA 133；3) high-gain is by a LNA
113 amplify and walk around the 2nd LNA 133；4) maximum gain is by a LNA 113 and
Both two LNA 133 amplify.
Fig. 2 shows the example according to present disclosure embodiment, and its middle controller 150 is true
Determine whether operate the first and second processors 110 and 130 in output control device.
With reference to Fig. 2, controller 150 determines whether to operate first and second in the reception cycle 200
Processor 110 and 130, and control first processor and the behaviour of the second processor 110 and 130
Make.The reception cycle 200 includes the variable automatic gain control for determining the numerical portion decision-making time
System (AGC) cycle 210.In view of measurable or measurable reception power, interference level,
Link State or desired data speed, initial gain can be set to and make the AGC cycle 210 minimum.
During the AGC cycle 210, yield value can be dependent on initial gain and increases or reduce.Initially
Gain can be set to high-gain based on receiving the relatively low hypothesis of power, or initial gain can base
It is set to low gain in receiving the higher hypothesis of power.This hypothesis can be based on the most previous increasing
Benefit sets.
If initial gain settings is high-gain, then controller 150 can be in the AGC cycle 210
Yield value is reduced to low gain from high-gain by period.For this purpose, controller 150 can lead to
Cross control the first switch 111, a LNA 113 is switched to OFF state from ON state.
Controller 150 also can make yield value increase to high-gain from low gain.For this purpose, control
Oneth LNA 113 can be switched to from OFF state by device 150 by controlling the first switch 111
ON state.
In order to make the reception level discontinuity that causes owing to being turned on and off a LNA 113 or
Link unstability is minimum, it may be considered that mode of operation before a LNA 113.
It is described below and processor is defined as in (that is, AGC cycle numerical portion decision-making time
The end time of 210) for receiving the operation (such as based on receiving power) of signal detection.Base
In reception level, interference level, Link State or data rate, non-reception power determines place
With based on reception power, the operation of reason device can determine that the operation of processor performs similarly.
Such as, during the AGC cycle 210, controller 150 can by control first switch and
Second switch 111 and 113 and operate the second processor 130, so that a LNA 113 closes
Close and the 2nd LNA 133 opens.This is referred to alternatively as the second reception state.Then, controller 150
Check with exported by the processing unit 100 in the second reception state amplify the merit that signal is relevant
Rate output valve.Then, controller 150 can be by controlling the first switch and second switch 111 He
113 operate first processor 110, so that a LNA 113 opens and the 2nd LNA 133
Close.This is referred to alternatively as the first reception state.Then, controller 150 checks and connects with by first
What the processing unit 100 in receipts state exported amplifies the power output valve that signal is relevant.
Controller 150 is in the numerical portion decision-making time (that is, the end time in AGC cycle 210)
The first switch and second switch 111 and 113 is controlled based on receiving the relevant value of state with second.
Can by the value relevant with the second reception state with can predetermined first threshold compare, with
The power attenuation making signal reception period is minimum.Even if first processor 110 is inoperative, control
Whether device 150 processed it is also determined that receive the relevant value of state more than first threshold with second.According to
Second receive the relevant value of state than first threshold big how much, controller 150 can determine that and only operates
Second processor 130, or neither operation first processor 110 does not the most operate the second processor
130.If receive the relevant value of state (Second Threshold is more than first more than Second Threshold with second
Threshold value), then this can be shown that the signal received is sufficiently strong and without being amplified.Therefore, control
Device 150 does not operate any one in first processor and the second processor 110 and 130.
On the other hand, if receiving the relevant value of state to be less than first threshold with second, then control
Device 150 can determine that only operation the second processor 130；If or signal is the most weak, then control
Device 150 operates both first processor and the second processor 110 and 130.Such as, if with
Second receives the relevant value of state is less than the 3rd threshold value (the 3rd threshold value is less than first threshold), then control
Both the operable first processor of device 150 processed and the second processor 110 and 130.Connect with second
The relevant value of receipts state can be dependent on design equal to the situation of first threshold and/or implements.Such as,
According to default, controller 150 can determine whether that operating first processor 110 or second processes
Device 130.
Therefore, if receiving range is more than predetermined threshold, then controller 150 can control at first
Reason device 110 operates；If receiving range is less than predetermined threshold, then controller 150 is controlled
Make the second processor 130 to operate, minimum power is lost according to receiving range.Assume strong
From neighbouring spreading out of, weak signal spreads out of signal from afar.If needing maximum amplification, then control
Device 150 can control both first processor and the second processor 110 and 130 and operate；And
If needing minimum amplification, then controller 150 can control first processor and the second processor
110 and 130 do not operate.
Describe by first processor and the second processor 110 and 130 below with reference to Fig. 3
Power attenuation.
Fig. 3 shows the controller in the output control device according to present disclosure embodiment
The exemplary operation of 150.
Embodiment according to present disclosure, it is assumed that a LNA 113 be GaAs LNA also
There is the gain of NF and 20dB of 2dB, and the 2nd LNA 133 is CMOS LNA and has
There is the gain of NF and 20dB of 3.5dB.It is also supposed that switch 111 from antenna 105 to the first
There is the power loss of 1dB, the power of 1dB occurs from the 2nd LNA 133 to next contiguous block
Loss, the maximum loss of printed circuit board (PCB) (PCB) is 8.6dB.
In the output control device with above-mentioned environment configurations, in operating first, controller 150
First switch 111 can be set to and walk around a LNA 113 and second switch 131 is set to
The input of the 2nd LNA 133.Therefore, the only second processor 130 will receive the cycle 200
In the AGC cycle 210 Part I during be amplified.When the second processor 130 operates
Time, controller 150 can determine that system NF is 13.1dB and power attenuation is 240mW.
In operating second, the first switch 111 can be set to a LNA 113 by controller 150
Input and second switch 131 be set to walk around the 2nd LNA 133.Therefore, only first
Processor 110 can be carried out during the Part II in AGC cycle 210 in the reception cycle 200
Amplify.When first processor 110 operates, controller 150 can determine that system NF is 2.217dB
And power attenuation is 1120mW.
Therefore, can be observed, when the only second processor 130 is amplified, power is than only
There is first processor 110 little 910mW when operating.Or, first processor 110 needs behaviour
The power of make the second processor 130 up to 5.3 times operates.Therefore, if connect with second
The relevant value of receipts state is in the numerical portion decision-making time (that is, the end time in AGC cycle 210)
More than predetermined first threshold, then controller 150 only can operate the second processor 130 and not grasp
Make first processor 110, to save appreciable power.
It is described above the configuration of output control device according to present disclosure embodiment
With operation.Below, the method being used for description controlling power in output control device.
Fig. 4 shows according to present disclosure embodiment, in output control device
Control the flow chart of the method for power.
With reference to Fig. 4, when the controller 150 AGC cycle 210 in being contained in the reception cycle 200
When period starts to operate, in operation 401, controller 150 is by controlling the first switch 111
With second switch 131, only select to be lost the operation of lower powered second processor 130.Behaviour
Making in 403, controller 150 connects with second for inspection during the second processor 130 operation
The value that receipts state is relevant.
Then, in operation 405, controller 150 is by controlling the first switch 111 and second
Switch 131 selection is lost high-power first processor 110.In operation 407, controller
150 inspections when operating for first processor 110 receive, with first, the value that state is relevant.
If check in operation 403 receives the state relevant value spy more than predetermined threshold with second
Determine scope, then controller 150 can not perform to operate 405 and 407.
In operation 409, controller 150 determines based on the value relevant with the second reception state and is
No operation first processor and the second processor 110 and 130.In other words, if connect with second
The relevant value of receipts state is more than predetermined first threshold, then controller 150 determines at operation second
Reason device 130.On the other hand, if receiving the relevant value of state with second less than predetermined first
Threshold value, then controller 150 determines operation first processor 110.If it addition, connect with second
The relevant value of receipts state is more than predetermined Second Threshold, then controller 150 does not make the first process
Any processor in device and the second processor 110 and 130 is operable to.Or, if with
Second receives the relevant value of state is less than the 3rd predetermined threshold value, then controller 150 makes at first
Both reason device and the second processor 110 and 130 are operable to.
Therefore, controller 150 can determine according to the second reception state of the second processor 130
Whether LNA operates.Therefore, even if when the signal power fluctuation received, according to this
The output control device of disclosure embodiment also can reduce power attenuation and keep good connecing
