Patent ID: 8848634

Claim:
A base station apparatus that receives an uplink signal transmitted from a mobile station, comprising: hardware, including a processor; a determination unit implemented at least by the hardware and adapted to determine, based on at least one of reception quality of the uplink signal, a radio modulation scheme applied to the uplink signal, and notification information from the mobile station included in the uplink signal, inconsistency between a set value of a maximum transmission power which the mobile station actually imposes on the mobile station itself and an index value which is related to the maximum transmission power of the mobile station and is used in the base station apparatus for scheduling of a radio resource carrying the uplink signal without the mobile station reporting a transmission power upper-limit value associated with a power class of the mobile station, the notification information not including the transmission power upper-limit value, smaller one of the index value and the transmission power upper-limit value being set by the mobile station as the set value.
