Abstract

A method of wireless communication includes communicating by receiving by a first transceiver a first type of signal, receiving by a second transceiver a first type of signal, carrier aggregating the signals received by the first transceiver and the signal the second transceiver. The method includes detecting a second type of signal and switching the first transceiver to receive the second signal type while the second transceiver continues to receive the first type of signal.

Claims

1. A mobile device for wireless communication, comprising:

a carrier aggregation radio having two or more transceivers that are configured to aggregate two signals of a first signal type; and

at least one of the transceivers is further configured to receive a second signal type while at least one of the other transceivers continues to receive the first signal type.

2. The mobile device of claim 1, further comprising a transceiver controller that is configured to adjust a filter characteristic within the at least one of the transceivers to allow the at least one of the transceivers to receive the second signal type.

3. The mobile device of claim 1, further comprising a transceiver controller that is configured to switch filters in the at least one of the transceivers to allow the at least one of the transceivers to receive the second signal type.

4. The mobile device of claim 2, further comprising a baseband processor that is configured to detect the type of signal being received by the at least one transceiver;

wherein the baseband processor is configured to process a signal differently based on whether the transceiver is receiving the first signal type or the second signal type.

5. The mobile device of claim 2, wherein the transceiver controller informs a baseband processor regarding the change in the filter characteristic in the at least one of the transceivers and wherein the filter characteristic is a center frequency.

6. The mobile device of claim 1, wherein the first signal type is a WWAN signal and wherein the second signal type is a WLAN signal.

7. The mobile device of claim 1, further comprising a controller configured to transmit control signals to a plurality of single pole double throw switches of the at least one transceiver to create a signal path that bypasses a FDD duplexer.

8. The mobile device of claim 1, wherein the at least one of the transceivers include a plurality of single pole double throw switches that create a signal path to bypass a FDD duplexer.

9. A method for wireless communication, the method comprising:

receiving by a first transceiver a first type of signal;

receiving by a second transceiver a first type of signal;

carrier aggregating the signals received by the first transceiver and the signal the second transceiver;

detecting a second type of signal; and

switching the first transceiver to receive the second type of signal while the second transceiver continues to receive the first type of signal.

10. The method of claim 9, wherein the first transceiver and the second transceiver is configured to receive a WWAN signal during carrier aggregation.

11. The method of claim 9, wherein the first type of signal is a WWAN signal and the second type of signal is a WLAN signal.

12. The method of claim 9, wherein the switching is performed by a controller that is connected to the first transceiver;

further comprising sending a control signal to the first transceiver to bypass at least one FDD duplexer.

13. The method of claim 9, further comprising adjusting a characteristic of a filter within the first transceiver to allow the first transceiver to receive the second type of signal.

14. The method of claim 9, further comprises a transceiver controller that is configured to adjust a filter frequency and activate at least one of the single pole double throw switches within the at least one of the transceivers to allow the at least one transceiver to process the second signal type.

15. The method of claim 14, wherein the transceiver controller is configured to provide different control signals based on a signal that is being processed.

16. The method of claim 9, further comprising a transceiver controller configured to change at least one control signal to create a signal path within the first transceiver to process a second type of signal.

17. An apparatus for wireless communication, the apparatus comprising:

a means for carrier aggregating two signals of a first signal type received by a first transceiver and a second transceiver;

a means for receiving, by the first transceiver, a second signal type upon detecting a second signal type.

18. The apparatus of claim 17, further comprising a means for changing a characteristic of a filter within a first transceiver based on the second signal type.

19. The apparatus of claim 17, further comprising a means for detecting the second signal type.

20. The apparatus of claim 17, further comprising a mean for generating a first control signal to change the first transceiver to receive a second type of signal while the second transceiver continues to receive a first type of signal.
