Patent ID: 8311165

Claim:
An interference suppression method used in a reception station to suppress an interfering signal that has been superimposed on a desired signal, the desired signal being transmitted by a partner station with which the reception station is performing communication, the interference suppression method comprising steps of: identifying a transmission source, from which the reception station received a signal, as either (i) a suppression target transmission source that has a possibility of transmitting the interfering signal superimposed on the desired signal, or (ii) a non-suppression target transmission source that does not have the possibility of transmitting the interfering signal superimposed on the desired signal; acquiring, from the received signal, a characteristic amount of the received signal; suppressing, when the reception station receives the desired signal, the interfering signal superimposed on the desired signal (i) with use of the characteristic amount of the received signal when the suppression target transmission source is identified as the transmission source of the received signal, and (ii) without use of the characteristic amount of the received signal when the non-suppression target transmission source is identified as the transmission source of the received signal; generating a first surrounding terminal list showing a plurality of transmission source identifiers that indicate, in one-to-one correspondence, a plurality of transmission sources from which the reception station has received signals in the past; and obtaining, from the partner station, a second surrounding terminal list showing a plurality of transmission source identifiers that indicate, in one-to-one correspondence, a plurality of transmission sources from which the partner station has received signals in the past, wherein the identifying step identifies the transmission source of the received signal as either the suppression target transmission source or the non-suppression target transmission source in accordance with the first surrounding terminal list and the second surrounding terminal list.
