FIELD: radio engineering.
SUBSTANCE: in user terminal (UE), when physical channels for data transmission EUDCH are sent bypassing existing physical channels, ratio of peak and average powers (PAPR) of transport signal of ascending communication line is increased. Increase of PAPR depends on orthogonal codes with alternating coefficient of spectrum expansion (OKPKRS), which are assigned to corresponding physical channels and in-phase/quadrature (I/Q) channels.
EFFECT: minimisation of PAPR increase, stipulated by EUDCH channel by means of assignment of spectrum expansion coefficient to transmission channels.
