Abstract: A method of performing interference cancellation (IC) in a communication device having a plurality of transmitters and a plurality of receivers includes detecting a co-existence issue between a first transmitter and a first receiver; selecting the first transmitter for providing an input signal to IC circuit; selecting the first receiver, wherein each of the receivers has a corresponding filter, the first receiver having a filter for filtering a signal received by the first receiver to provide a first filtered signal; configuring the IC circuit based on parameters of the co-existence issue; generating an output signal based on the input signal and the parameters; selecting a filter, based on the filter of the first receiver, the selected filter configured to filter the output signal to provide a second filtered signal; and generating a cancellation signal based on the first and second filtered signals.

Abstract: A method of wireless communication includes communicating using a first radio based on a first radio technology; configuring a second radio based on a second radio technology different from the first radio technology to assist the first radio with a first-radio operation; and performing at least a portion of the first-radio operation at the second radio. The first-radio operation includes at least one of multiple subscriber identity module (SIM) page monitoring and page/data processing, higher order diversity data acquisition and processing, interference measurement and management, E-UTRAN cell global identifier (ECGI) determination and reporting, a reference signal time difference (RSTD) measurement, beacon detection for small cell identification, a minimization of drive test (MDT) measurement, and a speed estimation measurement. The first radio technology is a wireless wide area network (WWAN) technology and the second radio technology is a wireless local area network (WLAN) technology.

Abstract: An adjustable filter is responsive to a control signal to change a frequency response of the adjustable filter based on frequency spectrum information. The control signal may shift a center of the pass band from a first center frequency to a second center frequency and/or change a pass band bandwidth from a first bandwidth to a second bandwidth. In one example, the frequency spectrum information includes a status of an internal secondary radio. The frequency spectrum information may also indicate a region of operation where the frequency response is selected in accordance with the region.
