Abstract
Peak to average power ratio (PAPR) reduction with respect to signals of component carriers of a carrier aggregation configuration may be provided using preconfigured or fixed PRT location sequences (e.g., fixing the number and location of PRTs). A device transmitting signals of component carriers of a carrier aggregation configuration may perform PRT magnitude and phase optimization processing with respect to PRTs of a PRT location sequence using techniques, such as may use a signal to clipping noise ratio, tone reservation (SCR-TR) algorithm. Various PRT location sequence configurations, such as PRT sideband location sequence configurations, PRT inband location sequence configurations, etc., may be selected to facilitate reduction of PAPR associated with the data tones of one or more carrier aggregation component carriers, such as to satisfy a PAPR threshold. Other aspects and features are also claimed and described.
