摘要：
Method and an apparatus for application of distortion shaping when using Peak-to-Average Ratio (PAR) reduction. The apparatus obtains an input signal. The apparatus applies, on the input signal, the PAR reduction and the distortion shaping to form an output signal. A bandwidth associated with the distortion shaping covers multiple channel bandwidths comprised in the input signal, which multiple channel bandwidths are associated with one or more Radio Access Technologies (RATs). Embodiments herein facilitate the distortion shaping and applicability of PAR reduction, in particular in case one of the RATs is Global System for Mobile Communications (GSM) or similar and/or the input signal is associated with radio communications systems that support multiple RATs.
