Abstract: A communication device includes a receiving circuit, an uplink control information generating circuit, a transmitting circuit and a control circuit. The receiving circuit receives an uplink-downlink reconfiguration message from a communication station. The uplink control information generating circuit generates a plurality of uplink control information. The transmitting circuit transmits the uplink control information in a plurality of data frames, each of which comprises a plurality of subframes. The control circuit determines the subframe of the data frame to be an uplink subframe, a downlink subframe or a special subframe according to the uplink-downlink reconfiguration message. The uplink-downlink reconfiguration message configures the communication device to operate in one of valid uplink-downlink configurations. The control circuit configures the transmitting circuit to transmit the uplink control information in a subframe of the data frame, which is not configured to be the downlink subframe in the valid uplink-downlink configurations.
