Abstract:
1. A radio communication terminal for performing radio communication with a base station by adopting Orthogonal Frequency Division Multiple Access scheme using a frame including data signals and reference signals used for correction of the data signals, comprising: a determination unit configured to determine whether it is possible to perform good radio communication with the base station; a transmission frame generating unit configured to generate a transmission frame having a reduced number of reference signals if it is determined that it is possible to perform good radio communication with the base station; a transmission unit configured to transmit the transmission frame having the reduced number of reference signals as a notification signal to the base station, said notification signal being a transmission frame in which a predetermined reference signal is replaced with a null signal; and a correction unit configured to correct the data signals included in a received frame from the base station by using the reference signals included in the received frame, wherein the determination unit determines the number of reference signals based on a state of the radio communication with the base station.
