Abstract

An adaptive tuning method comprises the steps of: obtaining a statistical result; determining whether an adaptive tuning procedure is to be performed in accordance with the statistical result; obtaining reference information of the first wireless module; and performing the adaptive tuning procedure in accordance with the reference information.

Claims (33)

1. An adaptive tuning method for a combo wireless system comprising a first wireless module and a second wireless module, the method comprising the steps of:

obtaining a status of the second wireless module, wherein the status is a statistic result that is obtained by counting a number of times the second wireless module's transmitting a signal to the first wireless module within a predetermined time;

obtaining reference information of the first wireless module when the status of the second wireless module is larger than a threshold value; and

adaptively tuning the first wireless module or the second wireless module in accordance with the reference information.

2. The method of claim 1 , wherein the reference information is a received signal strength indication (RSSI) value, a bandwidth parameter, a packet error rate or the combination thereof.

3. The method of claim 2 , wherein the adaptively tuning the first wireless module or the second wireless module in accordance with the reference information step comprises at least one of the following steps; adjusting a transmit power of the first wireless module in accordance with the RSSI value;

adjusting a low noise amplifier (LNA) gain of the first wireless module in accordance with the RSSI value;

adjusting a transmit power of the second wireless module in accordance with the RSSI value;

adjusting a modulation and coding scheme (MCS) rate of the first wireless module in accordance with the RSSI value and the packet error rate;

determining whether the bandwidth parameter is to be adjusted in accordance with the RSSI value; or

determining whether a block acknowledge support function is to be enabled for the first wireless module in accordance with the RSSI value.

4. The method of claim 1 , wherein the signal is a Bluetooth active (BT_ACT) signal or a Bluetooth priority (BT_PRIO) signal.

5. The method of claim 1 , wherein the first wireless module is a wireless fidelity (WiFi) module.

6. The method of claim 1 , wherein the second wireless module is a Bluetooth module, a worldwide interoperability for microwave access is (WiMAX) module, a 3G module or an ultra-wideband (UWB) module.

7. The method of claim 1 , wherein a communication method for the first wireless module and the second wireless module is a 2-wire protocol, a 3-wire protocol or a 4-wire protocol.

8. A tuning apparatus for a combo wireless system comprising a first wireless module and a second wireless module, the apparatus comprising:

a detection unit configured to detect a status of the second wireless module, wherein the status is a statistic result that is obtained by counting the number of times the second wireless module's transmitting a signal to the first wireless module within a predetermined time;

a determining unit configured to determine whether the status of the second wireless module is larger than a threshold value;

an acquiring unit configured to obtain reference information of the first wireless module when the status of the second wireless module is larger than the threshold value; and

a tuning unit configured to perform a tuning procedure in accordance with the reference information, wherein the tuning procedure comprises adaptively tuning the first wireless module or the second wireless module.

9. The tuning apparatus of claim 8 , wherein the reference information is a received signal strength indication (RSSI) value, a bandwidth parameter, a packet error rate or the combination thereof.

10. The tuning apparatus of claim 9 , wherein the tuning procedure comprises at least one of the following steps:

adjusting a transmit power of the first wireless module in accordance with the RSSI value;

adjusting a low noise amplifier (LNA) gain of the first wireless module in accordance with the RSSI value;

adjusting a transmit power of the second wireless module in accordance with the RSSI value;

adjusting a modulation and coding scheme (MCS) rate of the first wireless module in accordance with the RSSI value and the packet error rate;

determining whether the bandwidth parameter is to be adjusted in accordance with the RSSI value; or

determining whether a block ACK support function of the first wireless module is to be enabled in accordance with the RSSI value.

11. The tuning apparatus of claim 8 , wherein the signal is a Bluetooth active (BT_ACT) signal or a Bluetooth priority (BT_PRIO) signal.

12. The tuning apparatus of claim 8 , wherein the first wireless module is a wireless fidelity (WiFi) module.

13. The tuning apparatus of claim 8 , wherein the second wireless module is a Bluetooth module, a worldwide interoperability for microwave access (WiMAX) module, a 3G module or an ultra-wideband (UWB) module.

14. The tuning apparatus of claim 8 , wherein a communication method for the first wireless module and the second wireless module is a 2-wire protocol, a 3-wire protocol or a 4-wire protocol.

15. The tuning apparatus of claim 8 , which is implemented with software, firmware, hardware, or a platform with a single processor or with multiple processors.
