What is claimed is:

1. A method comprising: sending a request to use shared radio frequency resources, wherein a second wireless block sends the request to a first wireless block, waiting for a time duration to elapse after the request is received, and allowing the second wireless block to use the shared radio frequency resources if the time duration is elapsed, wherein the first wireless block continues to operate in a low-power mode while the second block is allowed to use the shared radio frequency resources. 2. The method of claim 1, wherein the first wireless block and the second wireless block coexist in a wireless internet card.

3. The method of claim 1, wherein the first wireless block and the second wireless block share the radio frequency resources.

4. The method of claim 3, wherein the request is sent from the second wireless block while the control of the shared radio frequency is with the first wireless block.

5. The method of claim 4, wherein the first wireless block operates on a first wireless standard and the second wireless block operates on a second wireless standard.

6. The method of claim 5, further comprises checking if a response is received before waiting for the time duration to elapse, and using the shared radio frequency resources if the response indicates that the shared radio frequency resources is available to be used.

7. The method of claim 1 further comprises starting to mask the request while the first wireless block is entering the low-power mode. 8. The method of claim 7 further comprises stopping to mask the request while the first wireless block is entering an active power mode. 9. An apparatus comprising: a front end comprising shared frequency resources, a first wireless block coupled to the front end, a second wireless block coupled to the front end, wherein the second wireless block is to send a request to the first wireless block to use shared radio frequency resources, and a coexistence block coupled to the second wireless block and the first wireless block, wherein the coexistence block is to wait for a time duration to elapse after the request is received and to allow the second wireless block to use the shared radio frequency resources if the time duration is elapsed, wherein the first wireless block is to operate in a low-power mode while the second block is allowed to use the shared radio frequency resources.

10. The apparatus of claim 9, wherein the first wireless block and the second wireless block coexist in a wireless internet card.

11. The apparatus of claim 9, wherein the first wireless block and the second wireless block share the radio frequency resources. 12. The apparatus of claim 11, wherein the second wireless block is to send the request to the first wireless block while the first wireless block is in control of the shared radio frequency resource.

13. The apparatus of claim 12, wherein the first wireless block operates on a first wireless standard and the second wireless block operates on a second wireless standard. 14. The apparatus of claim 13, the coexistence block further comprises a counter, wherein the counter is to keep track of the time duration, and a control logic coupled to the counter, wherein the control logic is to determine the time duration

15. The apparatus of claim 14, the coexistence block further comprises a status register coupled to the control logic, wherein a first bit of the status register is set by the first wireless block while the first wireless block enters the low-power mode and resets the first bit while entering the active power mode.

16. The apparatus of claim 14, wherein the control logic is to check if a response is received before waiting for the time duration to elapse and allow the shared radio frequency resources to be used by the second wireless block if the response indicates that the shared radio frequency resources is available to be used.

17. The apparatus of claim 9, wherein the first wireless block is to start mask the request while the first wireless block is entering the low-power mode.

18. The apparatus of claim 17, wherein the first wireless block is to mask the request while the first wireless block is entering an active power mode.

19. The apparatus of claim 18, wherein first wireless block is to stop masking the request while the first wireless block is entering an active power mode.

20. A machine-readable storage medium comprising a plurality of instructions that in response to being executed result in a processor comprising: sending a request to use shared radio frequency resources, wherein a second wireless block sends the request to a first wireless block, waiting for a time duration to elapse after the request is received, and allowing the second wireless block to use the shared radio frequency resources if the time duration is elapsed, wherein the first wireless block continues to operate in a low-power mode while the second block is allowed to use the shared radio frequency resources.

21. The machine-readable storage medium of claim 19, wherein the first wireless block and the second wireless block coexist in a wireless internet card.

22. The machine-readable storage medium of claim 19, wherein the first wireless block and the second wireless block share the radio frequency resources.

23. The machine-readable storage medium of claim 21, wherein the request is sent from the second wireless block while the control of the shared radio frequency is with the first wireless block.

24. The machine-readable storage medium of claim 22, wherein the first wireless block operates on a first wireless standard and the second wireless block operates on a second wireless standard.

25. The machine-readable storage medium of claim 23, further comprises checking if a response is received before waiting for the time duration to elapse, and using the shared radio frequency resources if the response indicates that the shared radio frequency resources is available to be used.

26. The machine-readable storage medium of claim 19 further comprises starting to mask the request while the first wireless block is entering the low-power mode.

27. The machine-readable storage medium of claim 25 further comprises stopping to mask the request while the first wireless block is entering an active power mode.

28. A system comprising: a processor, a chipset coupled to the processor, and a wireless internet card couple to the chipset, wherein the wireless internet card comprises, a front end comprising shared frequency resources, a first wireless block coupled to the front end, a second wireless block coupled to the front end, wherein the second wireless block is to send a request to the first wireless block to use shared radio frequency resources, and a coexistence block coupled to the second wireless block and the first wireless block, wherein the coexistence block is to wait for a time duration to elapse after the request is received and to allow the second wireless block to use the shared radio frequency resources if the time duration is elapsed, wherein the first wireless block is to operate in a low-power mode while the second block is allowed to use the shared radio frequency resources. 29. The system of claim 28, wherein the first wireless block and the second wireless block coexist in a wireless internet card, wherein the first wireless block and the second wireless block share the radio frequency resources.

30. The system of claim 29, wherein the second wireless block is to send the request to the first wireless block while the first wireless block is in control of the shared radio frequency resource.
