The invention has for its object to provide a base station for UMTS which makes it possible to implement the transmission of different transmission methods and of different time-slot types in the simplest possible manner. The base station according to the invention is a so-called node B of a UMTS mobile radio system. It includes a downlink power control unit. This unit is designed to transfer to a so-called chip processing unit for carrying out the CDMA coding at least one unit of information about at least one time-slot type to be transmitted. The downlink power control unit is a processor, for example. The implementation is done by suitable software programming of the processor. Using the received information, the chip processing unit generates a suitable time-slot type for a current time slot. This time-slot type is then CDMA-coded.
A base station for a UMTS mobile radio system which serves to transmit CDMA-coded radio signals formatted in time slots, wherein a transmit power control unit is designed to transfer to a processing unit at least one unit of information about a time-slot type to be transmitted in the form of at least one four-bit combination, with each bit representing one parameter of a time-slot type.
A base station for a UMTS mobile radio system which serves to transmit CDMA-coded radio signals formatted in time slots, wherein a transmit power control unit is designed to transfer to a processing unit at least one unit of information about a time-slot type to be transmitted in the form of at least one two-bit combination, with each bit combination representing a different time-slot type.
A downlink control unit for a base station for a UMTS mobile radio system, which serves to transmit CDMA-coded radio signals formatted in time slots, characterized in that a transmit power control unit is designed to transfer to a processing unit at least one unit of information about at least one time-slot type to be transmitted in the form of at least one four-bit combination, with each bit representing one parameter of a time-slot type.
