Abstract

In a method and arrangement for channel allocation in a radio communication system that uses a TD/CDMA subscriber separation method, an allocation of at least one channel is signalled to a radio station by an information element in a signalling message. At least one time slot is thereby selected by a time slot selection sub-information element. Subsequently, at least one CDMA code is selected for each selected time slot with a code selection sub-information element, whereby a number of code selection sub-information elements corresponds to a number of selected time slots.
