摘要： A radio communications system conducts radio communications using basic physical channels. Each basic physical channel defines a time slot and a radio frequency for transmission. Radio communication is established between a radio base station and multiple UEs over the same basic physical channel. Three or four subchannels are provided in the same basic physical channel to simultaneously support three or four full rate UE communications, seven or eight half rate UE communications, or other equivalent combinations. A first baseband transmitter chain can map full rate data corresponding to first and second full rate UE communications (or equivalent) as adaptive quadrature phase shift keying, AQPSK, signals onto a first and a second of the three subchannels. A second baseband transmitter chain can map full rate data corresponding to a third and/or fourth full rate UE communication (or equivalent) as phase shifted signals onto a third of the three subchannels.

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.
