Dynamically managing band capability

1. A method, comprising:

camping on a first radio access network (RAN) on a first Radio Frequency (RF) channel using a first receiver and transmitter and a second RAN on a second RF channel using a second receiver and transmitter;

determining, by a user equipment (UE) and based on a stored channel conflict table, that the first RF channel conflicts with the second RF channel, wherein the channel conflict table includes conflict information indicating whether one or more RF channels in a first frequency band conflicts with one or more RF channels in a second frequency band, and the first frequency band overlaps with the second frequency band, and wherein the conflict table is constructed based on at least one of a channel bandwidth of the first RAN, a channel bandwidth of the second RAN, and a guard band requirement;

receiving, by the UE, an indication from the first RAN to establish a radio connection on the first RF channel using the first receiver and transmitter; and

in response to the UE determining that the first RF channel conflicts with the second RF channel based on the stored channel conflict table and receiving the indication from the first RAN to establish the radio connection on the first RF channel:

connecting, by the UE, to the first RAN on the first RF channel using the first receiver and transmitter; and

disabling, by the UE and based on the stored channel conflict table, a frequency band of the second receiver and transmitter, wherein the frequency band includes the second RF channel with the second RAN.

2. The method of claim 1 , wherein the camping is performed in a Radio Resource Control (RRC) Idle state.

3. The method of claim 1 , wherein the determination includes using a band conflict table.

4. The method of claim 1 , wherein the first RAN and the second RAN comprise different types of radio access technologies.

5. The method of claim 1 , wherein the first RAN is a UMTS Terrestrial Radio Access Network (UTRAN).

6. A user equipment (UE), comprising:

a first receiver and transmitter configured to camp on a first radio access network (RAN) on a first Radio Frequency (RF) channel;

a second receiver and transmitter configured to camp on a second RAN on a second RF channel; and

one or more processors configured to:

determine, by the UE and based on a stored channel conflict table, that the first RF channel conflicts with the second RF channel, wherein the channel conflict table includes conflict information indicating whether one or more RF channels in a first frequency band conflicts with one or more RF channels in a second frequency band, and the first frequency band overlaps with the second frequency band, and wherein the conflict table is constructed based on at least one of a channel bandwidth of the first RAN, a channel bandwidth of the second RAN, and a guard band requirement;

receive, by the UE, an indication from the first RAN to establish a radio connection on the first RF channel using the first receiver and transmitter; and

in response to the UE determining that the first RF channel conflicts with the second RF channel based on the stored channel conflict table and receiving the indication from the first RAN to establish the radio connection on the first RF channel:

connect, by the UE, to the first RAN on the first RF channel using the first receiver and transmitter; and

disable, by the UE and based on the stored channel conflict table, a frequency band of the second receiver and transmitter, wherein the frequency band includes the second RF channel with the second RAN.

7. The UE of claim 6 , wherein the camping is performed in a Radio Resource Control (RRC) Idle state.

8. The UE of claim 6 , wherein the determination includes using a band conflict table.

9. The UE of claim 6 , wherein the first RAN and the second RAN comprise different types of radio access technologies.

10. The UE of claim 6 , wherein the first RAN is a UMTS Terrestrial Radio Access Network (UTRAN).

11. An apparatus comprising instructions embodied on a tangible, non-transitory computer-readable medium, the instructions operable when executed to cause a computing system to perform operations comprising:

camping on a first radio access network (RAN) on a first Radio Frequency (RF) channel using a first receiver and transmitter and a second RAN on a second RF channel using a second receiver and transmitter;

determining, by a user equipment (UE) and based on a stored channel conflict table, that the first RF channel conflicts with the second RF channel, wherein the channel conflict table includes conflict information indicating whether one or more RF channels in a first frequency band conflicts with one or more RF channels in a second frequency band, and the first frequency band overlaps with the second frequency band, and wherein the conflict table is constructed based on at least one of a channel bandwidth of the first RAN, a channel bandwidth of the second RAN, and a guard band requirement;

receiving, by the UE, an indication from the first RAN to establish a radio connection on the first RF channel using the first receiver and transmitter; and

in response to the UE determining that the first RF channel conflicts with the second RF channel based on the stored channel conflict table and receiving the indication from the first RAN to establish the radio connection on the first RF channel:

connecting, by the UE, to the first RAN on the first RF channel using the first receiver and transmitter; and

disabling, by the UE and based on the stored channel conflict table, a frequency band of the second receiver and transmitter, wherein the frequency band includes the second RF channel with the second RAN.

12. The apparatus of claim 11 , wherein the camping is performed in a Radio Resource Control (RRC) Idle state.

13. The apparatus of claim 11 , wherein the determination includes using a band conflict table.

14. The apparatus of claim 11 , wherein the first RAN and the second RAN comprise different types of radio access technologies.
