Abstract: The disclosure provides for interference mitigation for wireless signals in unlicensed spectrum. A wireless device may receive a combined signal including a first radio access technology (RAT) signal and a second RAT signal. The wireless device may generate, using a first RAT receiver in a first processing path, a channel estimate for the first RAT signal based on a previously decoded signal of the first RAT. The wireless device may reduce interference to the second RAT signal caused by the first RAT signal, in a second processing path, using the channel estimate. The wireless device may further decode the second RAT signal. The wireless device may remodulate the decoded signal using a transmitter to generate a remodulated second RAT signal. The remodulated second RAT signal may be canceled from the combined signal. The wireless device may decode a remaining portion of the combined signal including the first RAT signal.

Abstract translation: 本公开提供了在无许可频谱中的无线信号的干扰减轻。 无线设备可以接收包括第一无线电接入技术（RAT）信号和第二RAT信号的组合信号。 无线设备可以基于第一RAT的先前解码的信号，使用第一处理路径中的第一RAT接收机生成第一RAT信号的信道估计。 使用信道估计，无线设备可以在第二处理路径中减少由第一RAT信号引起的对第二RAT信号的干扰。 无线设备可以进一步解码第二RAT信号。 无线设备可以使用发射机重新解码解码的信号，以产生重新调制的第二RAT信号。 重新调制的第二RAT信号可以从组合信号中消除。 无线设备可以解码包括第一RAT信号的组合信号的剩余部分。
