Abstract: Various aspects described herein relate to interference cancellation. A received signal is received at a receiver chain, where the received signal is interfered by an aggressor signal transmitted using a transmitter chain. In a second portion of a time interval, one or more cancellation coefficients can be updated based on a measurement made in a first portion of the time interval, where the time interval can be within a protocol time interval of a protocol used by the transmitter chain. Based on the one or more updated cancellation coefficients, interference cancellation is performed to cancel interference of the aggressor signal from the received signal.

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.

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.
