Patent ID: 8331301

Claim:
A communication control method for determining whether information transmitted from a mobile station in a single-carrier scheme includes reception state information and acknowledgement information, comprising: a step in which the mobile station generates a first uplink control channel when transmitting reception state information, and the mobile station generates a second uplink control channel when transmitting reception state information and acknowledgement information; a step in which the mobile station transmits one of the first uplink control channel and the second uplink control channel; a step in which the base station receives one of the first and the second uplink control channels, performs first correlation detection for the received uplink control channel to obtain a first correlation value, and performs second correlation detection for the received uplink control channel to obtain a second correlation value; and a step in which the base station compares the first correlation value and the second correlation value, and determines that the mobile station has transmitted the reception state information if the first correlation value is greater than the second correlation value, and the base station determines that the mobile station has transmitted the reception state information and the acknowledgement information if the second correlation value is greater than the first correlation value.
