PROBLEM TO BE SOLVED: To provide a wireless access method capable of improving data transmission efficiency, reducing transmission delay, reducing the buffer amount of equipment even when frequently generating transmission data, miniaturizing an equipment and reducing power consumption by performing access again during idle time when this idle time is generated at the result data channel of scheduling the data channels of a fixed frame length. SOLUTION: A terminal station performs access to a reservation channel 21 (up) fixedly arranged at each frame and data channels 23 (up and down) are scheduled at a base station. The base station performs scheduling based on reservation information and when there is an idle time 24, it is reported to the terminal station to perform access during the idle time 24 while using a polling system, the random access method of data channels and the random access method of the reservation channels. Thus, the time of the data channel is suppressed from being wasted by the collision of the reservation channels, the data transmission efficiency is improved and the transmission delay can be reduced. |
