Power adjustment method and apparatus
An apparatus includes a receiving module, an obtaining module, an adjustment module, and a sending module, where the receiving module is configured to receive a signal sent by a terminal device; the obtaining module is configured to obtain a signal quality indicator according to the signal received by the receiving module, where the signal quality indicator is used to identify signal quality of a signal sent by the power adjustment apparatus and received by the terminal device; the adjustment module is configured to adjust a transmit power according to the signal quality indicator after the obtaining module obtains the signal quality indicator; and the sending module is configured to send a signal according to the transmit power adjusted by the adjustment module.
1. A power adjustment apparatus comprising:
a memory comprising instructions;
a receiver coupled to a processor and configured to receive a signal from a terminal device;
the processor coupled to the receiver and configured to:
obtain a signal quality indicator according to the signal; and
adjust a transmit power to an adjusted transmit power according to the signal quality indicator; and
a transmitter coupled to the processor and configured to transmit a second signal according to the adjusted transmit power, wherein the processor is further configured to:
collect statistics on minimum values of signal quality indicators at intervals of a first preset time period;
calculate an average value on the minimum values of signal quality indicators at intervals of a second preset time period; and
adjust the transmit power according to the average value.
2. The power adjustment apparatus of claim 1 , wherein the signal quality indicator is a signal quality value or a noise quality value, and wherein the signal quality value identifies a quality of the signal sent by the power adjustment apparatus and received by the terminal device, and wherein the noise quality value identifies a noise of the signal received by the terminal device.
3. The power adjustment apparatus of claim 1 , wherein the instructions further cause the processor to be configured to:
determine, according to the average value, a preset range to which the average value belongs, wherein the preset range comprises subranges arranged according to a preset rule and corresponding to transmit powers; and
further adjust the transmit power according to the preset range.
4. The power adjustment apparatus of claim 1 , wherein the signal quality indicator is a signal quality value, and wherein the instructions further cause the processor to be configured to:
determine a change trend of the average value according to successive average values; and
further adjust the transmit power according to the change trend of the average value.
5. The power adjustment apparatus of claim 1 , wherein the signal quality indicator is a signal quality value, and wherein the instructions further cause the processor to be configured to:
determine, according to the average value, a preset range to which the average value belongs;
determine a change trend of the average value according to successive average values; and
further adjust the transmit power according to the preset range and the change trend.
6. The power adjustment apparatus of claim 1 , wherein the instructions further cause the processor to be configured to use the signal quality indicator to identify a signal quality of the signal received at the terminal device.
7. A power adjustment method comprising:
receiving a signal from a terminal device;
obtaining a signal quality indicator according to the signal;
adjusting a transmit power to an adjusted transmit power according to the signal quality indicator;
transmitting a second signal according to the adjusted transmit power;
determining minimum values of signal quality indicators at intervals of a first preset time period;
calculating an average value of the minimum values of signal quality indicators at intervals of a second preset time period; and
further adjusting the transmit power according to the average value.
8. The power adjustment method of claim 7 , wherein the signal quality indicator is a signal quality value or a noise quality value, and wherein the signal quality value identifies a quality of the signal sent by the power adjustment apparatus and received by the terminal device, and wherein the noise quality value identifies a noise of the signal received by the terminal device.
9. The power adjustment method of claim 7 , wherein adjusting the transmit power according to the signal quality indicator further comprises:
determining, according to the average value, a preset range to which the average value belongs, wherein the preset range comprises subranges arranged according to a preset rule and corresponding to transmit powers; and
further adjusting the transmit power according to the preset range.
10. The power adjustment method of claim 7 , wherein the signal quality indicator is a signal quality value, and wherein adjusting the transmit power according to the signal quality indicator further comprises:
determining a change trend of the average value according to successive average values; and
further adjusting the transmit power according to the change trend of the average value.
11. The power adjustment method of claim 7 , wherein the signal quality indicator is a signal quality value, and wherein adjusting the transmit power according to the signal quality indicator further comprises:
determining, according to the average value, a preset range to which the average value belongs;
determining a change trend of the average value according to successive average values; and
further adjusting the transmit power according to the preset range and the change trend.
12. The power adjustment method of claim 7 , further comprising using the signal quality indicator to identify a signal quality of the signal received at the terminal device.
