Abstract
A user equipment (UE) mitigates in-device interference caused by a simultaneous circuit-switched call on a first subscriber identity module (SIM) and another call on a second subscriber identity module (SIM) at the UE. The UE detects in-device interference between the circuit switched call and the other call. The UE then suspends the other call or reduces a transmit power of the other call when the in-device interference is above a predetermined threshold. The UE resumes the other call or increases the transmit power of the other call when the circuit switched call ends.
Claims28
A method of wireless communication, comprising:
- detecting in-device interference between a first circuit switched call and another call in a multi subscriber identity module, multi active device;
- determining whether a hardware solution is implemented to mitigate the in-device interference;
- suspending the other call or reducing a transmit power of the other call when the in-device interference is above a predetermined threshold when the implemented hardware solution is unsuccessful;
- and
- resuming the other call or increasing the transmit power of the other call when the first circuit switched call ends.
(canceled)
An apparatus for wireless communication, comprising:
- means for detecting in-device interference between a first circuit switched call and another call in a multi subscriber identity module, multi active device;
- means for determining whether a hardware solution is implemented to mitigate the in-device interference;
- means for suspending the other call or reducing a transmit power of the other call when the in-device interference is above a predetermined threshold when the implemented hardware solution is unsuccessful;
- and
- means for resuming the other call or increasing the transmit power of the other call when the first circuit switched call ends.
(canceled)
An apparatus for wireless communication, comprising:
- a memory;
- and
- at least one processor coupled to the memory and configured:
- to detect in-device interference between a first circuit switched call and another call in a multi subscriber identity module, multi active device;
- to determine whether a hardware solution is implemented to mitigate the in-device interference;
- to suspend the other call or reduce a transmit power of the other call when the in-device interference is above a predetermined threshold when the implemented hardware solution is unsuccessful;
- and
- to resume the other call or increase the transmit power of the other call when the first circuit switched call ends.
(canceled)
A computer program product for wireless communication, comprising:
- a non-transitory computer-readable medium having program code recorded thereon, the program code comprising:
- program code to detect in-device interference between a first circuit switched call and another call in a multi subscriber identity module, multi active device;
- program code to determine whether a hardware solution is implemented to mitigate the in-device interference;
- program code to suspend the other call or reduce a transmit power of the other call when the in-device interference is above a predetermined threshold when the implemented hardware solution is unsuccessful;
- and
- program code to resume the other call or increase the transmit power of the other call when the first circuit switched call ends.
