Patent number: 8848634Abstract: One object of the present invention is to make a base station detect inconsistency between an uplink maximum transmission power P_CMAX actually set by a mobile station, and a maximum transmission power P_EMAX allowed by the base station for the mobile station without making the mobile station report to the base station about a transmission power upper-limit value P_UMAX associated with a power class of the mobile station. A base station (10) determines inconsistency between a set value P_CMAX of a maximum transmission power which a mobile station (13) actually imposes on itself and an index value P_RMAX of the maximum transmission power used in the base station (10) for scheduling a radio resource carrying an uplink signal.Type: GrantFiled: March 16, 2010Date of Patent: September 30, 2014Assignee: NEC CorporationInventors: Yuki Kogure, Takahiro Nobukiyo
