摘要： A wireless communication system includes a mobile station and a base station. The base station includes a blind decoding control unit that transmits a signal including a control signal serving as a trigger to change a decoding process to the mobile station based on a result of measurement of the amount of data of the mobile station. The mobile station includes a blind decoding control unit that selects a signal format to be decoded upon reception of the control signal from the base station, and detects a control signal directed to the mobile station by decoding the signal having the selected format among signals received from the base station.

摘要： A first radio communication apparatus includes a controller and a transmitter. The controller determines timing capable of transmitting a control parameter used for a process for establishing connection to a second radio communication apparatus when the connection is not established between the first and second radio communication apparatus. The transmitter transmits a message including data different from the control parameter to the second radio communication apparatus at determined timing. The second radio communication apparatus includes a receiver and a data processing unit. The receiver receives from the first radio communication apparatus the message transmitted at timing at which the first radio communication apparatus is able to transmit the control parameter. The data processing unit extracts data included in the received message.
