RADIO TRANSMISSION APPARATUS AND RADIO TRANSMISSION METHOD

摘要

PROBLEM TO BE SOLVED: To improve throughput in a wireless communication network system. SOLUTION: In a mobile terminal apparatus (STA) 120, MΓtransmission/reception sections 122-1 to 122-MΓare corresponding to MΓantennas 121-1 to 121-MΓ, respectively and transmit preamble signals and data signals via the corresponding antennas 121-1 to 121-MΓ. Each of the MΓtransmission/reception sections 122-1 to 122-MΓuses for transmitting a preamble signal a sub-carrier which is assigned for each of the antennas 121-1 to 121-MΓ, among sub-carriers 141, 142, 143, 144. Furthermore, each of the MΓtransmission/reception sections 122-1 to 122-MΓuses for transmitting a data signal a sub-carrier 140 having a frequency different from those of the sub-carriers 141, 142, 143, 144.
