Abstract
Systems and methods for mitigating known interference at a receiving device are provided. A signal from a transmission source is received by a receiving device that is affected by an interference source. At least one of a first pilot signal associated with the transmission source and a second pilot signal associated with the interfering source is determined. The first pilot signal includes information broadcast from the transmission source and the second pilot signal includes information broadcast from the interference source. Interference caused by the interference source is mitigated from the received signal using at least one of the first pilot signal and the second pilot signal.

21. A method for mitigating interference in a receiving device, the method comprising:
-
receiving a signal from a transmission source that is affected by interference from an interference source; determining a first channel estimate corresponding to the transmission source and a second channel estimate corresponding to the interference source; determining, based on the first and the second channel estimates, an expected improvement in signal quality resulting from interference mitigation; and mitigating the interference caused by the interference source if the expected improvement in signal quality exceeds a threshold, wherein mitigating the interference is based on the second channel estimate and assistance information. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30)

31. A system for mitigating interference, the system comprising:
-
a receiver configured to receive a signal from a transmission source that is affected by interference from an interference source; channel estimation circuitry configured to determine a first channel estimate corresponding to the transmission source and a second channel estimate corresponding to the interference source; control circuitry configured to determine, based on the first and the second channel estimates, an expected improvement in signal quality resulting from interference mitigation; and interference mitigation circuitry configured to mitigate the interference caused by the interference source if the expected improvement in signal quality exceeds a threshold, wherein mitigating the interference is based on the second channel estimate and assistance information. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38, 39, 40)
