Abstract: A method for wireless communication is described. A primary radio frequency integrated circuit (RFIC) supporting a plurality of radio frequency (RF) receive paths is provided. Standalone RF resources of a core-resource RFIC to integrate with the plurality of RF receive paths of the primary RFIC to enable an additional functionality of the primary RFIC are then added. A minimum set of RF resources necessary to add support for an additional RF receive path may be determined, and RF resources, including one or more of an antenna, an RF front end, and a low-noise amplifier (LNA) and switches of the primary RFIC, may be shared. A digital baseband integrated circuit (IC), i.e. a modem, may be operated to support both a first of the plurality of RF receive paths from the primary RFIC and a second of the plurality of RF receive paths from the core-resource RFIC.

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 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: 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: Various aspects described herein relate to providing analog interference cancellation using digitally computed coefficients. An aggressor signal can be obtained from a transmitter chain of a radio frequency (RF) front end. A digital representation of the aggressor signal can be generated, and cancellation coefficients can be estimated for the digital representation of the aggressor signal. An analog cancellation signal can be generated based at least in part the cancellation coefficients and the digital representation of the aggressor signal. The analog cancellation signal can be added to a victim signal in a receiver chain of the RF front end to cancel interference to the victim signal from the aggressor signal.
