Abstract
The radio communication apparatus includes: one or more radio units each with one or more antennas; a plurality of baseband processing units which perform baseband signal processing of signals, transceived by said radio units, in a frequency domain; and a connection interface which interfaces between said radio unit and any of said plurality of baseband processing units with signals in a frequency domain. With this arrangement, the transmission capacity of an interface inside the radio communication apparatus and power consumption are reduced, and the radio communication apparatus has superior flexibility and functional expandability for various types of services.

18. A radio unit with one or more transceiving antennas thereof, which radio unit is connected to a baseband processing apparatus that performs baseband signal processing in a frequency domain, to transceive signals processed on the baseband processing apparatus through the one or more transceiving antennas, said radio unit comprising:
-
time domain converting means which receives a signal having been subjected to the baseband signal processing on said baseband processing apparatus as a signal in a frequency domain, and converts the signal into a signal in a time domain; and
frequency domain converting means which converts a signal in a time domain, which signal is received through the transceiving antenna and is to be processed on said baseband processing apparatus, into a signal in a frequency domain, and then outputs the converted signal. - View Dependent Claims (19)
