Provided are a method of preparing a dicyclopentadiene-based resin and a dicyclopentadiene-based resin. According to the present invention, provided is a dicyclopentadiene-based resin including an aromatic olefin-based comonomer as a comonomer to have improved quality including high compatibility, a favorable color characteristic, and a low softening point, and also having improved adhesive strength due to a low molecular weight and a narrow molecular weight distribution.

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.
