Abstract: a system for performing peak current mitigation in an application programming subsystem (apss) dynamically performs mitigation based at least in part on power rail voltage and leakage current obtained at boot time. the voltage and leakage current obtained at boot time are used to estimate peak current. a map that is generated prior to boot time maps estimated peak current to throttling level and dictates different levels of throttling to be performed for different ranges of estimated peak current. at boot time, the map is used to map the estimated peak current to a level of throttling to be applied. if conditions at run time indicate that peak current is occurring or is likely to occur soon, the mapped level of throttling is applied to mitigate the peak current.

Abstract: methods, systems, and devices for wireless communications are described. a wireless communications device (e.g., a user equipment (ue) and/or a network entity) operating in a full-duplex operation mode may decode received signaling based on cancelling interference from transmitted signaling with a nlic model with inter-component carrier (cc) terms. the wireless communications device may transmit and receive signaling using overlapping time resources in the full-duplex operation mode, which may cause self-interference (si) due to the transmitted signaling interfering with the received signaling. thus, the wireless communication device may implement a nlic model to reduce, or remove, the si on a per-cc basis, while accounting for inter-cc terms. that is, the nlic model may include inter-cc terms, or kernels, that correspond to respective ccs of the transmitted signal.
