A UWB transmitting/receiving apparatus, a UWB transmitting/receiving terminal apparatus and a UWB transmitting/receiving system wherein a possibly reduced number of data retransmissions is achieved so as to raise the transmission efficiency. A UWB transmitting/receiving apparatus (100), which performs a UWB transmission, comprises a receiving part (400) that receives a propagation environment determination pulse transmitted from a UWB transmitting/receiving terminal apparatus (200), which also performs a UWB transmission, and a transmitting part (300) that transmits a data signal while the receiving part (400) is receiving the propagation environment determination pulse.
An ultra wideband transmitting/receiving apparatus that performs ultra wideband transmission, comprising:
An ultra wideband transmitting/receiving terminal apparatus that performs ultra wideband transmission using millimeter waves and quasi-millimeter waves, comprising, a transmitting section that transmits, upon requesting data signal transmission to an ultra wideband transmitting/receiving apparatus that performs the ultra wideband transmission, a propagation environment measurement pulse for measuring a propagation environment after an acknowledgement signal is received from the ultra wideband transmitting/receiving apparatus.
An ultra wideband transmitting/receiving system in which an ultra wideband transmitting/receiving apparatus and ultra wideband transmitting/receiving terminal apparatus perform ultra wideband transmission, wherein a data signal of the ultra wideband transmitting/receiving apparatus, data signal of the ultra wideband terminal apparatus, and a propagation environment measurement pulse for measuring a propagation environment transmitted from the ultra wideband terminal apparatus, are transmitted using a code of a unique pattern.
