PROBLEM TO BE SOLVED: To provide a radio signal receiver capable of reducing a buffering capacity and power consumption by reducing processing delay.SOLUTION: A radio signal receiver 200 related to the present invention includes: a demapping unit 205 for extracting a sub-frame 11 from a received radio signal, determining whether or not information concerning a signal 34 addressed to the receiver included in a data channel is present in a first OFDM symbol 12a present at the head of the sub-frame and constituting a control channel and if it is present, outputting a plurality of OFDM symbols 12b-12n; and a decryption unit 208 for decrypting the plurality of OFDM symbols that have been output from the demapping unit. When information concerning a signal addressed to the receiver is not present in the first OFDM symbol, the demapping unit terminates sub-frame reception processing.
