S401: in the digital control unit 103 of miniature power amplifier 40, pre-sets the time period of closing up power amplifier/descending power amplifier, namely can carry out the energy-conservation time period.Such as, this time period can be set to the some same day 22 to next day 8.
S402: detected the upward signal in this tiny area by up detecting unit 104.
Because be provided with energy saving period, so up detecting unit 104 only carries out detecting, to save unnecessary power consumption within this time period.
S403: when the intensity of the upward signal that up detecting unit 104 detects is less than pre-determined threshold, closes the descending power amplifier 1052 of up power amplifier 1051/ in this micro-area communication system.The size of this pre-determined threshold is any value between-20 to-100dBm, can be set to-55dBm in the present embodiment.
Concrete, the upward signal that user terminal (such as mobile phone) sends is received by cover antenna 102, enter upward signal link, to make an uproar through low first the amplification of amplifier 1061, be coupled certain energy, enters up detecting unit 104, then through the first gain adjustment unit 1071, first filter unit 1081, the up power amplifier 1051 of control switch, transfers to donor antenna 101 to first collecting unit 4081 that retransmits signal.Wherein, the upward signal detected by up detecting unit 104 is converted into switch controlling signal through digital control unit 103, controls the opening and closing of descending power amplifier 1052.
In the energy saving period preset, when the intensity of the upward signal detected by up detecting unit 104 is less than-55dBm, just can think there is no user terminal in this tiny area, then close the descending power amplifier 1052 of up power amplifier 1051/ by digital control unit 103, to control upstream noise interference, and save the power consumption of this miniature power amplifier system.
S404: when the intensity of the upward signal that up detecting unit 104 detects is greater than pre-determined threshold, open descending power amplifier 1052.
Concrete, when there being user's terminal to transmit uplink signal in this tiny area, or when having user terminal to enter this tiny area from other region, up detecting unit will detect that this user terminal sends upward signal, and the intensity of detected upward signal is when being greater than-55dBm, digital control unit will open up power amplifier/descending power amplifier, thus ensures the normal use of this user terminal in this tiny area.
The downstream signal that donor antenna 101 receives just can enter downstream signal link, descending power amplifier 1052 is entered through the second low noise amplifier 1062, Received signal strength collecting unit 4042, second filter unit 1082, to retransmit signal collecting unit 4082 through the second gain adjustment unit 1072, second again, exported by cover antenna 102.In addition, be also provided with isolation detecting unit 4091, monitoring unit 4092, power subsystem 4093 in miniature power amplifier system, match with digital control unit 103, realize the lower line output of signal.
Within the energy saving period preset, if the intensity of the upward signal detected by up detecting unit 104 is less than-55dBm again, then digital control unit 103 closes the descending power amplifier 1052 of up power amplifier 1051/ again.That is, within energy saving period, step S403 and step S404 can carry out according to the intensity circulation of detected upward signal.
Through checking, the power consumption that miniature power amplifier system uplink interference suppresses and power-economizing method is saved that the embodiment of the present invention provides, effectively can suppress the interference of upstream noise, and account for 30% to 60% of this miniature power amplifier system total power consumption, and the coverage of tiny area is less, effect is better.
The present invention can also be applied in the miniature power amplifier system of one-way type.
The above; be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; the change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claim.
