Abstract

A method of wireless communication includes identifying a first radio operating in a first mode and a second radio operating in a second mode defined within one device. The first radio and the second radio operate on a same radio access technology (RAT) and also operate on a same band. The method also includes altering a communication time of the first radio and/or the second radio to reduce interference.

Claims

1. A method of wireless communication, comprising:

identifying a first radio operating in a first mode and a second radio operating in a second mode defined within one device, the first radio and the second radio operating on a same radio access technology (RAT) and also operating on a same band; and

altering a communication of the first radio and/or the second radio to reduce interference.

2. The method of claim 1, in which the altering comprises altering communications of the first radio to be non-overlapping in time with communications of the second radio.

3. The method of claim 1, further comprises altering the band of the first radio to be different from the band of the second radio.

4. The method of claim 1, in which the altering comprises altering the communication of a third radio operating on a RAT that is different from the RAT of the first and second radio.

5. The method of claim 1, in which the first mode is an access point mode and the second mode is a station mode.

6. The method of claim 1, in which the first radio and the second radio are operating in the same end-to-end communication link.

7. An apparatus for wireless communications, comprising:

means for identifying a first radio operating in an first mode and a second radio operating in a second mode defined within one device, the first radio and the second radio operating on a same radio access technology (RAT) and also operating on a same band; and

means altering a communication of the first radio and/or the second radio to reduce interference.

8. The apparatus of claim 7, in which the means for altering comprises means for altering communications of the first radio to be non-overlapping in time with communications of the second radio.

9. The apparatus of claim 7, further comprises means for altering the band of the first radio to be different from the band of the second radio.

10. The apparatus of claim 7, in which the means for altering comprises means for altering the communication of a third radio operating on a RAT that is different from the RAT of the first and second radio.

11. The apparatus of claim 7, in which the first mode is an access point mode and the second mode is a station mode.

12. The apparatus of claim 7, in which the first radio and the second radio are operating in the same end-to-end communication link.

13. A computer program product for wireless communications, the computer program product comprising:

a non-transitory computer-readable medium having program code recorded thereon, the program code comprising;

program code to identify a first radio operating in an first mode and a second radio operating in a second mode defined within one device, the first radio and the second radio operating on a same radio access technology (RAT) and also operating on a same band; and

program code to alter a communication of the first radio and/or the second radio to reduce interference.

14. The computer program product of claim 13, in which the program code to alter further comprises program code to alter communications of the first radio to be non-overlapping in time with communications of the second radio.

15. The computer program product of claim 13, further comprises program code to alter the band of the first radio to be different from the band of the second radio.

16. The computer program product of claim 13, in which the program code to alter further comprises program code to alter the communication of a third radio operating on a RAT that is different from the RAT of the first and second radio.

17. The computer program product of claim 13, in which the first mode is an access point mode and the second mode is a station mode.

18. The computer program product of claim 13, in which the first radio and the second radio operate in the same end-to-end communication link.

19. An apparatus for wireless communications, comprising:

a memory; and

at least one processor coupled to the memory, the at least one processor being configured;

to identify a first radio operating in a first mode and a second radio operating in a second mode defined within one device, the first radio and the second radio operating on a same radio access technology (RAT) and also operating on a same band; and

to alter a communication of the first radio and/or the second radio to reduce interference.

20. The apparatus of claim 19, in which the at least one processor is further configured to alter communications of the first radio to be non-overlapping in time with communications of the second radio.

21. The apparatus of claim 19, in which the at least one processor is further configured to alter the band of the first radio to be different from the band of the second radio.

22. The apparatus of claim 19, in which the at least one processor is further configured to alter the communication of a third radio operating on a RAT that is different from the RAT of the first and second radio.

23. The apparatus of claim 19, in which the first mode is an access point mode and the second mode is a station mode.

24. The apparatus of claim 19, in which the first radio and the second radio operate in the same end-to-end communication link.
