Abstract

Implementations are presented herein that relate to Bluetooth® and Wireless Network Coexistence.

Claims

1. A method, comprising:

transmitting an instruction that a wireless communications capable apparatus is intending to enter a power savings mode, the instruction transmitted using a first wireless standard and prior to the wireless communications capable apparatus commencing a wireless communications session using a second wireless standard.

2. The method according to claim 1, wherein the transmitting of the instruction occurs although the wireless communications capable apparatus is not about to enter a power savings mode.

3. The method according to claim 1, wherein the first wireless standard is one of the Wireless Local Area Network (WLAN) standards 802.11x.

4. The method according to claim 1, wherein the second wireless standard is Bluetooth®

.

5. The method according to claim 1, wherein the transmitting includes transmitting a packet that includes a power savings mode bit enabled, the enabled power savings mode bit to instruct an apparatus receiving the packet to buffer data to distribute to an apparatus transmitting the packet.

6. The method according to claim 1, further comprising commencing a wireless communications session using the second wireless standard after the instruction has been transmitted.

7. The method according to claim 1, further comprising receiving an acknowledgement that the instruction was received, and commencing a wireless communications session using the second wireless standard after the acknowledgement is received.

8. A Wireless Local Area Network (WLAN) 802.11x and Bluetooth®

coexistence method, comprising;

enabling a power management bit to a position indicating a power savings mode; and

transmitting a communication including the power management bit enabled to the position indicating the power savings mode before commencing a Bluetooth®

session.

9. The method according to claim 8, wherein the transmitting transmits a packet including the power management bit enabled to the position indicating the power savings mode.

10. The method according to claim 8, further comprising receiving an acknowledgement that the communication including the enabled power management bit was received.

11. The method according to claim 8, further comprising commencing a Bluetooth®

session immediately after transmitting the communication including the enabled power management bit.

12. The method according to claim 8, further comprising receiving an acknowledgement that the communication including the enabled power management bit was received, and commencing a Bluetooth®

session after receiving the acknowledgment.

13. An apparatus having at least wireless capabilities, comprising:

at least one module to enable data transmissions using first and second wireless standard techniques; and

a processor associated with the at least one module, the processor to prepare a first instruction indicating an apparatus is in a power savings mode, the processor to issue the first instruction using a carrier signal based on the first wireless standard, the processor to issue the first instruction before the processor issues a second instruction to commence communications using the second wireless standard.

14. The apparatus according to claim 13, wherein the first wireless standard is one of the Wireless Local Area Network (WLAN) standards 802.11x.

15. The apparatus according to claim 13, wherein the second wireless standard is Bluetooth®

.

16. The apparatus according to claim 13, wherein the first instruction is a packet that includes a power savings mode bit enabled, the enabled power savings mode bit to instruct an apparatus to buffer data to distribute to an apparatus transmitting the packet.

17. The apparatus according to claim 13, further comprising a transmitter coupled to the processor, the transmitter to transmit the first instruction indicating an apparatus is in a power savings mode.

18. The apparatus according to claim 17, further comprising a receiver coupled to the processor, the receiver to receive an acknowledgement that the first instruction has been received.

19. The apparatus according to claim 13, wherein the processor issues the second instruction immediately after the issuance of the first instruction, the issuance of the second instruction allowing an apparatus to commence communications using the second wireless standard.

20. The apparatus according to claim 13, wherein the processor issues the second instruction after the issuance of the first instruction and after an acknowledgement is received that indicates that the first instruction was received.

21. The apparatus according to claim 13, wherein the first instruction is a packet that includes a power savings mode bit enabled, the enabled power savings mode bit to instruct an apparatus receiving the packet to buffer data to distribute to an apparatus transmitting the packet.
