Abstract: The present invention relates to a method of configuring a user equipment-based communication area in a cloud radio access network environment and an apparatus therefor. As one embodiment of the present invention, a method of performing a communication, which is performed by a user equipment (UE) in a cloud radio access network environment includes the steps of generating an RRU list based on signal strength of downlink signals received from each of one or more RRUs (remote resource unit), setting a UE-based communication area in a manner of transmitting the RRU list to a BBU (base band unit) via a first RRU among the one or more RRUs and establishing an RRC connection with a second RRU within the UE-based communication area.
