Abstract

Aspects of a method and system for a shared antenna control using the output of a voice activity detector are provided. A single radio chip for use within a wireless device may handle communication of a Bluetooth (BT) and a Wireless Local Area Network (WLAN) protocol via a single antenna. Simultaneous reception via BT and WLAN channels may be enabled. The single radio chip may enable detection of voice activity in the BT channel and may reduce the BT transmission priority level some time after the voice activity indicates that the BT channel is not transmitting voice information to enable error concealment. Voice activity detection may be based on PCM samples in the BT channel. The single radio chip may transmit an ACK signal to an access point after the BT transmission priority level is reduced.

Claims

1. A method for handling wireless signals, the method comprising:

detecting voice activity in at least one of a first wireless protocol channel and a second wireless protocol channel in a radio chip within a wireless device that handles communication for said first wireless protocol channel and said second wireless protocol channel via a single antenna; and

adjusting a transmission queue in said radio chip based on said detected voice activity.

2. The method according to claim 1, wherein said first wireless protocol channel is a Bluetooth (BT) channel.

3. The method according to claim 1, wherein said second wireless protocol channel is a Wireless Local Area Network (WLAN) channel.

4. The method according to claim 1, comprising adjusting said transmission queue when at least one of said first wireless protocol channel and said second wireless protocol channel is not transmitting voice information.

5. The method according to claim 1, comprising generating at least one signal that adjusts said transmission queue.

6. The method according to claim 1, comprising adjusting a transmission schedule of an acknowledge (ACK) signal for packets received via one of said first wireless protocol channel and said second wireless protocol channel based on said detected voice activity.

7. The method according to claim 1, comprising adjusting said transmission queue a specified period of time after detected voice activity indicates that at least one of said first wireless protocol channel and said second wireless protocol channel is not transmitting voice information.

8. The method according to claim 1, comprising detecting said voice activity based on PCM voice samples from at least one of said first wireless protocol channel and said second wireless protocol channel.

9. A machine-readable storage having stored thereon, a computer program having at least one code section for handling wireless signals, the at least one code section being executable by a machine for causing the machine to perform steps comprising:

detecting voice activity in at least one of a first wireless protocol channel and a second wireless protocol channel in a radio chip within a wireless device that handles communication for said first wireless protocol channel and said second wireless protocol channel via a single antenna; and

adjusting a transmission queue in said radio chip based on said detected voice activity.

10. The machine-readable storage according to claim 9, wherein said first wireless protocol channel is a Bluetooth (BT) channel.

11. The machine-readable storage according to claim 9, wherein said second wireless protocol channel is a Wireless Local Area Network (WLAN) channel.

12. The machine-readable storage according to claim 9, comprising code for adjusting said transmission queue when at least one of said first wireless protocol channel and said second wireless protocol channel is not transmitting voice information.

13. The machine-readable storage according to claim 9, comprising code for generating at least one signal that adjusts said transmission queue.

14. The machine-readable storage according to claim 9, comprising code for adjusting a transmission schedule of an acknowledge (ACK) signal for packets received via one of said first wireless protocol channel and said second wireless protocol channel based on said detected voice activity.

15. The machine-readable storage according to claim 9, comprising code for adjusting said transmission queue a specified period of time after detected voice activity indicates that at least one of said first wireless protocol channel and said second wireless protocol channel is not transmitting voice information.

16. The machine-readable storage according to claim 9, comprising code for detecting said voice activity based on PCM voice samples from at least one of said first wireless protocol channel and said second wireless protocol channel.

17. A system for handling wireless signals, the system comprising:

one or more circuits that enable detecting voice activity in at least one of a first wireless protocol channel and a second wireless protocol channel in a radio chip within a wireless device that handles communication for said first wireless protocol channel and said second wireless protocol channel via a single antenna; and

said one or more circuits enable adjustment of a transmission queue in said radio chip based on said detected voice activity.

18. The system according to claim 17, wherein said first wireless protocol channel is a Bluetooth (BT) channel.

19. The system according to claim 17, wherein said second wireless protocol channel is a Wireless Local Area Network (WLAN) channel.

20. The system according to claim 17, wherein said one or more circuits enable adjustment of said transmission queue when at least one of said first wireless protocol channel and said second wireless protocol channel is not transmitting voice information.

21. The system according to claim 17, wherein said one or more circuits enable generation of at least one signal that adjusts said transmission queue.

22. The system according to claim 17, wherein said one or more circuits enable adjustment of a transmission schedule of an acknowledge (ACK) signal for packets received via one of said first wireless protocol channel and said second wireless protocol channel based on said detected voice activity.

23. The system according to claim 17, wherein said one or more circuits enable adjustment of said transmission queue a specified period of time after detected voice activity indicates that at least one of said first wireless protocol channel and said second wireless protocol channel is not transmitting voice information.

24. The system according to claim 17, wherein said one or more circuits enable detection of said voice activity based on PCM voice samples from at least one of said first wireless protocol channel and said second wireless protocol channel.
