20130003890 | METHOD AND APPARATUS FOR REDUCING TRANSMITTER INTERFERENCE - A method and apparatus mitigates spurious transmissions. An offset local oscillator signal is generated that is at a frequency that is offset from a nominal transmit channel carrier frequency by a spurious mitigation offset. An information signal is generated that comprises a series of modulation symbols and has a transmission bandwidth at baseband. A configured offset information signal is generated from the information signal, wherein the spectrum of the configured offset information signal is offset from DC by a channel configuration offset, and is further offset by a negative of the spurious mitigation offset. The offset local oscillator signal and the configured offset information signal are combined using a mixing technique. The spurious mitigation offset is zero when a spurious condition does not exist and is non-zero when the spurious condition does exist. | 01-03-2013 |

20140378180 | METHOD AND NETWORK ENTITY FOR REDUCING INTER-NETWORK INTERFERENCE - Wireless networks share UE location information in order to identify possible inter-network aggressors. If a first network determines, based on the location data it receives from a second network, that one of the first network's UEs may cause excessive interference to one or more of the second network's UEs, the first network grants A-MPR to its UE (e.g., by signaling the UE). The first network's UE can then lower its transmit power in order avoid interfering with the second network's UE. | 12-25-2014 |
