<p>A method for obtaining a channel use time for transmitting uplink data is provided to guarantee transmission of uplink data by automatically obtaining a channel available time for transmitting the uplink data. The first device is permitted to exclusively use the first channel use time, set for data transmission, by the second device. The first device transmits information about a protocol for using the first channel use time. The first device permits an exclusive use of the second channel use time received from the second device. It is checked whether the second channel use time is a channel use time for uplink data transmission. The first device checks whether the second channel use time to be used by the protocol is a channel use time for uplink data transmission based on the information on the protocol for using the second channel use time received from the second device.</p> |
