MULTI-HOP COMMUNICATION TERMINAL, MULTI-HOP COMMUNICATION SYSTEM, AND MULTI-HOP COMMUNICATION METHOD
Publication number: 20140140229Abstract: In a gateway (GW), when interference is detected by an interference detection unit, a frame generation unit sends an interference broadcast signal. A terminal receives the interference broadcast signal sent at a maximum transmission power from the GW to which the terminal belongs. The interference broadcast signal includes information on a planned transmission power value that is a transmission power value of a data signal in the GW and is smaller than the maximum transmission power value. The interference broadcast signal is sent at the maximum transmission power value.Type: ApplicationFiled: September 4, 2013Publication date: May 22, 2014Applicant: FUJITSU LIMITEDInventors: Hiroshi FUJITA, Kazuyuki OZAKI, YUN WEN -
