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, at a first wireless device, a first radio operating in a station mode to communicate with a remote access point while a second radio operates in an access point mode to serve as an access point for a second wireless device, the first radio having a first transmit/receive chain and the second radio having a second transmit/receive chain that is different from the first transmit/receive chain such that information from transmissions/receptions of the first radio is different in comparison to information from transmissions/receptions of the second radio, and the first radio and the second radio are operating in different end-to-end communication links;

identifying, at the first wireless device, the second radio operating in the access point mode while the first radio operates in the station mode, the first radio and second radio being 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. An apparatus for wireless communications, comprising:

means for identifying, at a first wireless device, a first radio operating in a station mode to communicate with a remote access point while a second radio operates in an access point mode to serve as an access point for a second wireless device, the first radio having a first transmit/receive chain and the second radio having a second transmit/receive chain that is different from the first transmit/receive chain such that information from transmissions/receptions of the first radio is different in comparison to information from transmissions/receptions of the second radio, and the first radio and the second radio are operating in different end-to-end communication links;

means for identifying, at the first wireless device, the second radio operating in the access point mode while the first radio operates in the station mode, the first radio and second radio being 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 for altering a communication of the first radio and/or the second radio to reduce interference.

6. The apparatus of claim 5, 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.

7. The apparatus of claim 5, further comprises means for altering the band of the first radio to be different from the band of the second radio.

8. The apparatus of claim 5, 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.

9. A non-transitory computer-readable medium having program code recorded thereon for wireless communication, the program code comprising:

program code to identify, at a first wireless device, a first radio operating in a station mode to communicate with a remote access point while a second radio operates in an access point mode to serve as an access point for a second wireless device, the first radio having a first transmit/receive chain and the second radio having a second transmit/receive chain that is different from the first transmit/receive chain such that information from transmissions/receptions of the first radio is different in comparison to information from transmissions/receptions of the second radio, and the first radio and the second radio are operating in different end-to-end communication links;

program code to identify, at the first wireless device, the second radio operating in the access point mode while the first radio operates in the station mode, the first radio and second radio being 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.

10. The non-transitory computer-readable medium of claim 9, 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.

11. The non-transitory computer-readable medium of claim 9, further comprises program code to alter the band of the first radio to be different from the band of the second radio.

12. The non-transitory computer-readable medium of claim 9, 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.

13. 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, at a first wireless device, a first radio operating in a station mode to communicate with a remote access point while a second radio operates in an access point mode to serve as an access point for a second wireless device, the first radio having a first transmit/receive chain and the second radio having a second transmit/receive chain that is different from the first transmit/receive chain such that information from transmissions/receptions of the first radio is different in comparison to information from transmissions/receptions of the second radio, and the first radio and the second radio are operating in different end-to-end communication links;

to identify, at the first wireless device, the second radio operating in the access point mode while the first radio operates in the station mode, the first radio and second radio being 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.

14. The apparatus of claim 13, 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.

15. The apparatus of claim 13, 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.

16. The apparatus of claim 13, 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.
