5.3 Physical uplink shared channel

36.2113GPPEvolved Universal Terrestrial Radio Access (E-UTRA)Physical channels and modulationRelease 17TS

The baseband signal representing the physical uplink shared channel is defined in terms of the following steps:

– scrambling

– modulation of scrambled bits to generate complex-valued symbols

– mapping of the complex-valued modulation symbols onto one or several transmission layers

– transform precoding to generate complex-valued symbols

– precoding of the complex-valued symbols

– mapping of precoded complex-valued symbols to resource elements

– generation of complex-valued time-domain SC-FDMA signal for each antenna port
