Abstract:
1. A wireless communication base station device configured to use a first wireless communication scheme and a second wireless communication scheme which use overlapping bands, the device comprising: a measuring section which measures a first transmission and reception time spent on actual data transmission and reception during a first communication-enabled period in which data communication based on the first wireless communication scheme is permitted, and measures a second transmission and reception time spent on actual data transmission and reception during a second communication-enabled period in which data communication based on the second wireless communication scheme is permitted; and a communication period determining section which determines lengths of the first and second communication-enabled periods in accordance with the first and second transmission and reception times measured by the measuring section, wherein if transmitted and received data requests an acknowledge signal for the data, the measuring section calculates the first and second transmission and reception times by summing time required to transmit the data, time required to transmit and receive the acknowledge signal, and time from completion of transmission and reception of the data until start of transmission and reception of the acknowledge signal, and if the transmitted and received data does not request an acknowledge signal for the data, the measuring section calculates each of the first and second transmission and reception times to be equal to the time required to transmit and receive the data.
