Patent number: 9763202Abstract: To suitably perform information transfer, while suppressing interference to other terminal stations, and preventing a reduction of a transmission opportunity of other terminal stations. A terminal station estimates a distance of another terminal station (within a receivable range), from an MCS or RSSI, for example, and controls a transmission power of itself, in accordance with a value weighted with respect to distance. For example, in the case where it is estimated that a number of terminal stations with a far distance has increased, from the value weighted with respect to distance, a transmission power of itself is lowered. As a result of this, transmission by multi-hop is explicitly performed, and it is possible to suppress electric wave interference of a multi-hop destination.Type: GrantFiled: May 30, 2014Date of Patent: September 12, 2017Assignee: SONY CORPORATIONInventors: Yoshihiko Ikenaga, Kazuyuki Sakoda, Nobuhiko Watanabe, Chihiro Fujita
