Abstract

An interference management scheme may detect a level of uncoordinated interference and compare a detected uncoordinated interference level against an intra-RAT (radio access technology) interference. Intra-RAT interference management algorithms or intra-RAT interference solutions are not triggered/applied if the uncoordinated interference is dominant. Alternatively, intra-RAT interference management algorithms may be triggered if co-channel intra-RAT interference is dominant.

Claims

1. A method of wireless communication, the method comprising:

detecting a level of uncoordinated interference;

detecting a level of intra-RAT (radio access technology) interference; and

implementing an intra-RAT interference solution based at least in part on the level of uncoordinated interference or the level of intra-RAT interference and based at least in part on a determination of a priority of a UE (user equipment), the determination of the priority based at least in part on a difference between the level of uncoordinated interference and the level of intra-RAT interference and an achieved throughput.

2. The method of claim 1, in which detecting the level of uncoordinated interference is based at least in part on a waveform of an interfering RAT.

3. The method of claim 1, in which detecting the level of uncoordinated interference is based at least in part on a temporal or frequency domain pattern of the interference.

4. The method of claim 1, further comprising adjusting an allowable interference level based at least in part on the level of uncoordinated interference or the level of intra-RAT interference.

5. The method of claim 1, in which implementing the intra-RAT interference solution further comprises initiating an intra-RAT interference solution, halting an intra-RAT interference solution or and/or modifying an intra-RAT interference solution.

6. An apparatus for wireless communication, comprising:

means for detecting a level of uncoordinated interference;

means for detecting a level of intra-RAT (radio access technology) interference; and

means for implementing an intra-RAT interference solution based at least in part on the level of uncoordinated interference or the level of intra-RAT interference and based at least in part on a determination of a priority of a UE (user equipment), the determination of the priority based at least in part on a difference between the level of uncoordinated interference and the level of intra-RAT interference and an achieved throughput.

7. The apparatus of claim 6, in which the means for detecting the level of uncoordinated interference detects based at least in part on a waveform of an interfering RAT.

8. The apparatus of claim 6, in which the means for detecting the level of uncoordinated interference detects based at least in part on a temporal or frequency domain pattern of the interference.

9. The apparatus of claim 6, further comprising a means for adjusting an allowable interference level based at least in part on the level of uncoordinated interference or the level of intra-RAT interference.

program code to implement an intra-RAT interference solution based at least in part on the level of uncoordinated interference or the level of intra-RAT interference and based at least in part on a determination of a priority of a UE (user equipment), the determination of the priority based at least in part on a difference between the level of uncoordinated interference and the level of intra-RAT interference and an achieved throughput.

11. The computer-readable medium of claim 10, in which the program code to detect the level of uncoordinated interference bases the detection at least in part on a waveform of an interfering RAT.

12. The computer-readable medium of claim 10, in which the program code to detect the level of uncoordinated interference bases the detection at least in part on a temporal or frequency domain pattern of the interference.

at least one processor coupled to the memory, the at least one processor being configured;

to detect a level of uncoordinated interference;

to detect a level of intra-RAT (radio access technology) interference; and

to implement an intra-RAT interference solution based at least in part on the level of uncoordinated interference or the level of intra-RAT interference and based at least in part on a determination of a priority of a UE (user equipment), the determination of the priority based at least in part on a difference between the level of uncoordinated interference and the level of intra-RAT interference and an achieved throughput.

15. The apparatus of claim 14, in which the at least one processor configured to detect a level of uncoordinated interference bases the detection at least in part on a waveform of an interfering RAT.
