Abstract: Various aspects described herein relate to providing analog interference cancelation in a shared antenna. A plurality of signals can be obtained at a plurality of reference points in a transmitter chain of a shared antenna. At least one reference point of the plurality of reference points from which to generate a cancelation signal and/or at least one injection point for injecting the cancelation signal can be selected based at least in part on expected analog interference cancelation metrics related to each of the plurality of reference points and/or the at least one injection point. The cancelation signal can be generated based at least in part on the at least one reference point and/or injection point. The cancelation signal can be injected in the injection point at a receiver chain of the shared antenna to cancel interference from signals generated at the transmitter chain of the shared antenna.

Abstract: A device may use enhanced power amplifier (PA) linearization techniques such as adaptive feed-forward (FF) linearization using adaptive filters. In one example, an adaptive feed-forward linearizer may isolate a distortion signal based at least in part on the signals input to and output from a PA in a transmission path. The distortion signal may be used to cancel distortion at the output of the PA to produce an improved output signal. A first adaptive circuit may be used to produce the distortion signal and a second adaptive circuit may be used to produce an error cancellation signal based at least in part on the distortion signal. The error cancellation signal may be amplified and re-introduced to the transmission path to produce the improved output signal. Semi-adaptive circuits may be used in place of the adaptive circuits, or a hybrid approach may be used.

Abstract: A wireless device may determine the level of interference mitigation appropriate for the application and dynamically select a combination of interference cancellation components that satisfies that level. The combination of interference cancellation components may include components that consume power ( e.g. , active components) and components that do not consume power ( e.g. , passive components). The interference cancellation components may be used at the transmitter and/or the receiver. In some cases, the wireless device may also determine how much power is acceptable to expend on the interference mitigation. In such scenarios, the selection of the interference cancellation components may be such that the aggregated power consumption is less than the power expenditure limit.

Abstract: A time period associated with each of a plurality of tasks included in a current instance of WWAN data capture/processing by a WLAN processor and a WWAN processor is determined. A total time period comprising the respective time periods of each task is compared to an overall time budget criterion to obtain a comparison outcome. A change in at least one of the tasks based on the comparison outcome is implemented. The change results in an adjustment of the total time period associated with a next instance of WWAN data capture/processing by the WLAN processor and the WWAN processor.
