Abstract

A UE may be configured to support wireless communication in two or more frequency bands. In some embodiments, the UE initiates a first wireless communication session in a first frequency band of the two or more frequency bands, and in response to initiating the wireless communication session in the first frequency band, the UE prevents itself from communicating in a second frequency band of the set of two or more frequency bands until the first wireless communication session has ended. Some embodiments further include subsequently enabling the UE to communicate in the second frequency band of the set of two or more frequency bands in response to ending the first wireless communication session in the first frequency band.

Claims

1. A method performed by a wireless user equipment device (UE) configured to support wireless communication in a set of two or more frequency bands, the method comprising:

initiating a first wireless communication session in a first frequency band of the two or more frequency bands; and

in response to initiating the first wireless communication session in the first frequency band, preventing the UE from communicating in a second frequency band of the set of two or more frequency bands until the first wireless communication session has ended, wherein preventing the UE from communicating in the second frequency band comprises activating one or more filters to block signal reception in the second frequency band.

2. The method of claim 1, further comprising:

ending the first wireless communication session in the first frequency band; and

in response to ending the first wireless communication session in the first frequency band, enabling the UE to communicate in the second frequency band of the set of two or more frequency bands.

3. The method of claim 1, wherein preventing the UE from communicating in a second frequency band of the set of two or more frequency bands until the first wireless communication session has ended further comprises:

powering off a radio in the UE configured to communicate in the second frequency band.

4. The method of claim 1, wherein preventing the UE from communicating in a second frequency band of the set of two or more frequency bands until the first wireless communication session has ended further comprises:

preventing the UE from communicating on all frequency bands of the set of two or more frequency bands other than the first frequency band until the first wireless communication session has ended.

5. The method of claim 1, wherein preventing the UE from communicating in a second frequency band of the set of two or more frequency bands until the first wireless communication session has ended further comprises:

preventing the UE from communicating in a selected plurality of the set of two or more frequency bands other than the first frequency band until the first wireless communication session has ended.

6. The method of claim 1, wherein the first wireless communication session is a voice over IP communication session or a video communication session.

7. The method of claim 1, wherein the first frequency band includes a single range of frequencies.

8. The method of claim 1, wherein the first frequency band includes a first range of frequencies and a second range of frequencies, wherein the first and second ranges are noncontiguous.

9. The method of claim 1, wherein the UE is a Long Term Evolution (LTE) device, wherein the first frequency band includes at least one of LTE bands 25 or 26, and wherein the second frequency band includes LTE band 41.

10. A wireless user equipment device (UE) comprising:

one or more radios configured to support wireless communications in a set of two or more frequency bands;

one or more processors configured to (i) initiate a first wireless communication session in a first frequency band of the set of two or more frequency bands, and (ii) in response to initiating the first wireless communication session in the first frequency band, prevent the UE from communicating in a second frequency band of the set of two or more frequency bands until the first wireless communication session has ended wherein preventing the UE from communicating in the second frequency band comprises activating one or more filters to block signal reception in the second frequency band.

11. The UE of claim 10, wherein the one of more processors are further configured to enable the UE to communicate in the second frequency band of the set of two or more frequency bands in response to ending the first wireless communication session in the first frequency band.

12. The UE of claim 10, wherein preventing the UE from communicating in the second frequency band further comprises powering off a radio of the one or more radios that is configured to communicate in the second frequency band.

13. The UE of claim 10, wherein in response to initiating the first wireless communication session in the first frequency band, the one of more processors are further configured to prevent the UE from communicating on all frequency bands of the set of two or more frequency bands other than the first frequency band until the first wireless communication session has ended.

14. The UE of claim 10, wherein in response to initiating the first wireless communication session in the first frequency band, the one of more processors are further configured to prevent the UE from communicating in a selected plurality of the set of two or more frequency bands other than the first frequency band until the first wireless communication session has ended.

15. The UE of claim 10, wherein the first wireless communication session is a voice over IP communication session or a video communication session.

16. The UE of claim 10, wherein the first frequency band includes a single range of frequencies.

17. The UE of claim 10, wherein the first frequency band includes a first range of frequencies and a second range of frequencies, wherein the first and second ranges are noncontiguous.

18. The UE of claim 10, wherein first frequency band includes at least one of Frequency Division Duplex (FDD) band, and wherein the second frequency band includes at least one Time Division Duplex (TDD) band.
