The embodiments of the invention relate to a method of allocating a radio resource and a device utilizing the same. The method comprises: a transmitter determines, according to an identification (ID) of a receiver at a present state, and based on a redefined rule, a channel time-frequency location where a control channel associated with the present state of the receiver is; and the transmitter transmits, via the control channel at the channel time-frequency location, and to the receiver, data time-frequency location indication information, a size of time-frequency resource occupied by data, and a data modulation and coding scheme. In the method of allocating the radio resource and the device utilizing the same according to the embodiments of the invention, the transmitter determines, according to the ID of the receiver at the present state, the time-frequency location where the control channel associated with the present state of the receiver is, and indicates, via the control channel, and to the receiver, the time-frequency location for transmitting data, flexibly allocating control channels for use by a transmitter and receiver by actual requirements, increasing efficiency, performance, and adaptability of a wireless communication system.
