Abstract:
1. A radio integrated circuit having an sending/receiving section that is to restore reception data in a predetermined format by demodulating a radio signal sent conformingly to a predetermined radio communication standard, and to send, with modulation, acknowledgement data generated according to information designated by the reception data, by means of a radio signal conforming to the radio communication standard, and a data-link section that is to receive the reception data restored in the sending/receiving section and to generate the acknowledgement data when there is designated an acknowledgement for the reception data, wherein said sending/receiving section comprises: a registering part that registers an address of a destination of communication for which data to be sent has been prepared; a first holding part that monitors the reception data under restoration and holds frame control information, of the reception data, containing information concerning a representing form of a source address; a decoding part that decodes the frame control information held in the first holding part and outputs information about a data length and structure of address field representative of the source address in the reception data; a second holding part that holds the source address out of the reception data under restoration, according to the data length and structure of address field outputted from the decoding part; and a comparing part that compares the source address held in the second holding part with the address of the destination of communication registered in the registering part and provides a result of comparison to the data-link section.
