Abstract

Certain embodiments of the invention may be found in a method and system for collaborative coexistence between Bluetooth and IEEE 802.11 g with both technologies integrated onto an SOC device. In a single integrated circuit (IC) that handles Bluetooth and WLAN technologies, a WLAN priority level may be selected for WLAN transmissions and a Bluetooth priority level may be selected for Bluetooth transmissions. The WLAN and Bluetooth priority levels may be selected from a plurality of priority levels. A packet transfer scheduler (PTS) may schedule the transmission of WLAN and Bluetooth signals in accordance with the selected priority levels. In some instances, the PTS may promote or demote the priority levels for WLAN and/or Bluetooth transmissions based on traffic needs.

Claims

A method for providing wireless communication, the method comprising scheduling WLAN communication and Bluetooth communication in a single radio chip that handles at least a Bluetooth (BT) communication protocol and a Wireless Local Area Network (WLAN) communication protocol based on priority levels assigned to said WLAN communication and Bluetooth communication.

2. The method according to claim 1, further comprising promoting said priority level assigned to said WLAN communication.

3. The method according to claim 1, further comprising demoting said priority level assigned to said WLAN communication.

4. The method according to claim 1, further comprising promoting said priority level assigned to said Bluetooth communication.

5. The method according to claim 1, further comprising demoting said priority level assigned to said Bluetooth communication.

6. The method according to claim 1, further comprising modifying said priority level assigned to said Bluetooth communication based on said WLAN communication.

7. The method according to claim 1, further comprising modifying said priority level assigned to said WLAN communication based on said BT communication.

8. A machine-readable storage having stored thereon, a computer program having at least one code section for providing wireless communication, the at least one code section being executable by a machine for causing the machine to perform steps comprising scheduling WLAN communication and Bluetooth communication in a single radio chip that handles at least a Bluetooth (BT) communication protocol and a Wireless Local Area Network (WLAN) communication protocol based on priority levels assigned to said WLAN communication and Bluetooth communication.

9. The method according to claim 8, further comprising code for promoting said priority level assigned to said WLAN communication.

10. The method according to claim 8, further comprising code for demoting said priority level assigned to said WLAN communication.
