    • A method and device for communicating data within a packet frame unit between a terminal and a base station are disclosed. The terminal communicates the packet data to the base station. In response, the base station transmits a channel occupying signal, if the data transmission from the terminal is perceived by the base station. The terminal continues the communication of the packet data, while the channel occupying signal is active, determines whether the base station receives the communicated packet data, and ends the process for communicating the packet data if the base station receives the communicated packet data. If the base station fails to receive the communicated packet data, the terminal is informed through the channel occupying signal. Thereafter, the terminal discontinues its communication and then re-attempts to communicate the packet data from the beginning.
