Coexistence operation method and related wireless system
View Patent ↗The present invention provides a coexistence operation method for a wireless system, wherein the wireless system is capable of establishing a first wireless link and a plurality of second wireless link. The coexistence operation method comprises applying different time slots to the first wireless link and a first link of the second wireless links; and applying a different frequency band to a second link of the second wireless links when is the different time slots are applied to the first wireless link and the first link of the second wireless links.
1. A coexistence operation method for a wireless system, the wireless system capable of establishing a first wireless link and a plurality of second wireless link, the coexistence operation method comprising:
performing data transmission of the first wireless link in a plurality of first time slots;
performing data transmission of a first link of the second wireless links in a plurality of second time slots;
applying a first frequency range to a second link of the second wireless links only during the plurality of first time slots; and
applying a second frequency range to the second link of the second wireless links during the plurality of second time slots, wherein the first frequency range is different from the second frequency range;
wherein the first wireless link and the first link of the second wireless links use Time-Division Multiplexing, the first wireless link and the second link of the second wireless links use Frequency-Division Multiplexing and the first wireless link belongs to a first wireless technology, and the second wireless links belong to a second wireless technology different from the first wireless technology.
2. The coexistence operation method of claim 1 , wherein the step of applying the first frequency range to the second link of the second wireless links comprises:
operating the first wireless link at a low level.
3. The coexistence operation method of claim 1 , wherein the first wireless link is Wi-Fi link and the second wireless links are Bluetooth links.
4. The coexistence operation method of claim 1 , further comprising powering down the second link of the second wireless links and the first wireless link.
5. The coexistence operation method of claim 1 , wherein the first frequency range of the second link of the second wireless links is farther from a frequency range of the first wireless link than a frequency range of the first link of the second wireless links.
6. The coexistence operation method of claim 1 , wherein the second link of the second wireless links has better Received Signal Strength Indicator (RSSI) than the first link of the second wireless links does.
7. A wireless system comprising:
a first wireless module for establishing a first wireless link and applying a plurality of first time slots to a first wireless link; and
a second wireless module for establishing a first link of second wireless links with a first device, and establishing a second link of second wireless links with a second device, and performing data transmission of the first link of the second wireless links and data transmission of the second link of the second wireless links in a plurality of second time slots and applying a first frequency range to the second link of the second wireless links only during the plurality of first time slots, and applying a second frequency range to the second link of the second wireless links during the plurality of second time slots, wherein the first frequency range is different from the second frequency range;
wherein the first wireless module is a Wi-Fi module while the first wireless link is Wi-Fi link and the second wireless module is Bluetooth module while the second wireless links are Bluetooth links;
wherein the first wireless link and the first link of the second wireless links use Time-Division Multiplexing, the first wireless link and the second link of the second wireless links use Frequency-Division Multiplexing.
8. The wireless system of claim 7 , wherein the first wireless module comprises a first amplifier, and the first amplifier is operated at a low level when the first frequency range is applied to the second link of the second wireless links.
9. The wireless system of claim 7 , wherein the first wireless module further performs data transmission of the first wireless link in the first time slot.
10. The wireless system of claim 9 , wherein the second wireless module further performs data transmission of the first link of the second wireless links in the second time slot and performs data transmission of the second link of the second wireless links in the first time slot and the second time slot.
11. The wireless system of claim 7 , wherein the first wireless link and the second link of the second wireless links are powered down.
12. The wireless system of claim 7 , wherein the first frequency range of the second link of the second wireless links is farther from a frequency range of the first wireless link than a frequency range of the first link of the second wireless links.
13. The wireless system of claim 7 , wherein the second link of the second wireless links has better Received Signal Strength Indicator (RSSI) than the first link of the second wireless does.
