    摘要： In a wireless communication system having a wireless base station, wireless terminal stations belonging to a first group which performs wireless communication while sharing different frequency channels, and wireless terminal stations belonging to a second group which performs wireless communication by using one frequency channel, a first communication period and a second communication period is alternately repeated. In this system, a wireless terminal station belonging to the first or the second group communicates with the wireless base station by using a first frequency channel in the first communication period. Direct communication between two wireless terminal stations belonging to the first group by using a second frequency channel without through the wireless base station is performed in the first communication period. Then, a wireless terminal station belonging to the first group communicates with the wireless base station by using both the first and the second frequency channels.

    摘要： A radio base station apparatus used in a radio communication system in which an initiator holds a transmission opportunity (TXOP) period in a frame exchange sequence and a responder responds to the initiator in the frame exchange sequence is disclosed. The apparatus includes a setting device which sets a ratio between a first period necessary for transmitting a first frame from the initiator to the responder and a second period necessary for transmitting a second frame from the responder to the initiator. The apparatus also includes a calculation device which calculates the first period to be used by the initiator and the second period to be used by the responder, on the basis of the transmission opportunity period and of the ratio which is set.
