Abstract: A method for ranging in a wireless communication system and a communication apparatus and/or system using the same are provided. A base station (BS) device includes a terminal grouping unit to group terminals associated with the BS device into a plurality of groups, a radio resource assignment unit to allocate a radio resource assigned to the BS device to each of the plurality of groups, a transmission unit to transmit information about a radio resource assigned to a first group of the plurality of groups to a terminal included in the first group, and a receiving unit to receive a ranging signal from the terminal using the radio resource assigned to the first group, wherein the terminal grouping unit assigns the terminal to be included in a second group of the plurality of groups where the ranging signal is not received by the receiving unit.
