Abstract

Briefly, some embodiments of the invention provide devices, systems and methods of multiple transceivers control. For example, a method in accordance with an embodiment of the invention may include determining whether interference is expected between an intended activity of a first wireless transceiver of a wireless communication station and an activity of a second wireless transceiver of said wireless communication station; and based on the determination result, modifying an operational parameter of an interference reducer of said wireless communication station.

Claims

1. A method comprising:

determining from a stored prior transmission/reception indication from a first wireless transceiver of a wireless communication station whether interference is expected between an intended activity of a second wireless transceiver of a said wireless communication station and an activity of the first wireless transceiver of said wireless communication station; and

based on the determination result, modifying an operational parameter of an interference reducer of said wireless communication station;

wherein determining comprises determining whether interference is expected based on an entry in a lookup table indicating whether a first signal transmitted in accordance with a first wireless communication standard is expected to interfere with a second signal transmitted in accordance with a second wireless communication standard.

2. The method of claim 1, wherein determining comprises:

determining whether interference is expected based on one or more activity mode indications received from said first and second wireless transceivers.

3. The method of claim 1, wherein modifying comprises:

deactivating said interference reducer if the determination result is that interference is not expected.

4. The method of claim 1, wherein modifying comprises:

activating said interference reducer if to determination result is that interference is expected.

5. The method of claim 1, wherein modifying comprises:

modifying an operational voltage of said interference reducer if the determination result is that interference is expected.

6. The method of claim 1, further comprising:

sending a signal to at least one of said first and second wireless transceivers indicating an instruction to modify said operational parameter of said interference reducer.

7. An apparatus comprising:

a controller to determine from a stored prior transmission reception indication from a first wireless transceiver of a wireless communication station whether interference is expected between an intended activity of a second wireless transceiver of a said wireless communication station and an activity of the first wireless transceiver of said wireless communication station, and, based on the determination result, to modify an operational parameter of an interference reducer of said wireless communication station; and

wherein said controller is to determine whether interference is expected based on an entry in a lookup table indicating whether a first signal transmitted in accordance with a first wireless communication standard is expected to interfere with a second signal transmitted in accordance with a second wireless communication standard.

8. The apparatus of claim 7, wherein said controller is to determine whether interference is expected based on one or more activity mode indications received from said first and second wireless transceivers.

9. The apparatus of claim 7, wherein said controller is to deactivate said interference reducer if the determination result is that interference is not expected.

10. The apparatus of claim 7, wherein said controller is to activate said interference reducer if the determination result is that interference is expected.

11. The apparatus of claim 7, wherein said controller is to modify an operational voltage of said interference reducer if the determination result is that interference is expected.

12. The apparatus of claim 7, wherein said controller is to send a signal to at least one of said first and second wireless transceivers indicating an instruction to modify said operational parameter of said interference reducer.

13. The apparatus of claim 7, wherein said interference reducer comprises an adaptive bias Voltage Controlled Oscillator.

14. A wireless communication station comprising:

the apparatus of claim 7; and

an antenna to send and receive wireless communication signals.

15. A wireless communication system comprising:

a wireless communication station having a controller to determine from a stored prior transmission/reception indication from a first wireless transceiver of said wireless communication station whether interference is expected between an intended activity of a second wireless transceiver of a said wireless communication station and an activity of the first wireless transceiver of said wireless communication station, and, based on the determination result, to modify an operational parameter of an interference reducer of said wireless communication station; and

wherein said controller is to determine whether interference is expected based on an entry in a lookup table indicating whether a first signal transmitted in accordance with a first wireless communication standard is expected to interfere with a second signal transmitted in accordance with a second wireless communication standard.

16. The wireless communication system of claim 15, wherein said controller is to determine whether interference is expected based on one or more activity mode indications received from said first and second wireless transceivers.

17. The wireless communication system of claim 15, wherein said controller is to deactivate said interference reducer if the determination result is that interference is not expected.

18. The wireless communication system of claim 15, wherein said controller is to activate said interference reducer if the determination result is that interference is expected.

19. The wireless communication system of claim 15, wherein said controller is to modify an operational voltage of said interference reducer if the determination result is that interference is expected.

20. The wireless communication system of claim 15, wherein said controller is to send a signal to at least one of said first and second wireless transceivers indicating an instruction to modify said operational parameter of said interference reducer.
