Abstract

According to the invention, signalling of the used common channels is carried out implicitly via the data rate. Several combinations of channels (spread codes) are only permitted as an alternative for particular data rates of the individual services. Transmission capacity is saved since it is not necessary to reserve individual bits inside the TFCI parameter uniquely for the allocation of said common channels to different connections. The invention is especially useful in the downlink of the FDD modus of UMTS mobile radio systems.
