Abstract
A method and device for adjusting communications power are used for detecting a communications condition between a connection port and a connection target, and a communications-supporting power of the connection port that includes at least one of a transmitting power and a receiving power is adjusted according to a detected communications condition. Therefore, accuracy of data transmission and reception is ensured, and power used for data transmission and reception is reduced.
Claims19
A method for adjusting a power of a connection port that is linked to a connection target, said method comprising:
- presetting first and second communication quality threshold values;
- generating an estimated communication quality according to at least one of packets transferred between the connection port and the connection target;
- decreasing a communications-supporting power of the connection port by one level when the estimated communication quality is lower than the first communication quality threshold value, wherein the communications-supporting power includes at least one of a transmitting power and a receiving power of the connection port;
- increasing the communications-supporting power of the connection port by one level when the estimated communication quality is higher than the second communication quality threshold value;
- and
- maintaining a current level of the communications-supporting power of the connection port when the estimated communication quality is neither lower than the first communication quality threshold value nor higher than the second communication quality threshold value.
A device for adjusting communications power, said device being adapted to connect to a connection port, and comprising:
- a reliable link error detecting circuit to receive packet information of packets received and transmitted by the connection port, to generate an estimated communication quality based on said packet information;
- to generate an adjustment command according the estimated communication quality and at least one communication quality threshold value, wherein the communications-supporting power of the connection port includes at least one of a transmitting power and a receiving power;
- and
- a power-saving controller coupled to said reliable link error detecting circuit to adjust the communications-supporting power of the connection port according to said adjustment command received from said reliable link error detecting circuit.
A method for adjusting a communication power comprising the steps of:
- providing a predetermined power to a communication port;
- using the predetermined power for establishing a connection between the communication port and a connection target over a channel;
- using a communications-supporting power for conducting the communication between the communication port and the connection target;
- computing an estimated communication quality of the channel between the communication port and the connection target;
- and
- determining whether to adjust the communications-supporting power according to the estimated communication quality.
