Method for managing wireless resource and apparatus therefor

A communication device configured to perform a communication with a user equipment in a wireless communication system, the communication device comprising:

• a radio frequency (RF) unit;
• and
• a processor operatively connected to the RF unit and configured to:
• receive, from the user equipment, information about a base station cluster, wherein the base station cluster comprises a plurality of base stations and is determined at the user equipment according to the following equation:
• M
• k
• =
• {
• m
• ∈
• M
• |
• S
• mk
• ≥
• w
• mk
• x
• k
• ⁢
• (

• }
• ,
• where Mk indicates the base station cluster, Smk indicates a strength of a signal received at a user equipment k from the plurality of base stations of the base station cluster, wmk indicates a value of a sum of signal strengths received at the user equipment k from the plurality of base stations, and that is divided by a resource allocation gain, xk, from a base station m of the plurality of base stations to the user equipment k, and ym indicates a value indicating load information of the base station m,
• generate a radio interface between the user equipment and a virtual cell based on information about the base station cluster, wherein the virtual cell is formed using the plurality of base stations;
• group a plurality of user equipments into a plurality of groups to satisfy a specific condition,
• select the user equipment from a group of the plurality of the groups for scheduling using a group-based greedy algorithm,
• wherein checking whether or not a total number of antennas of a base station corresponding to each group is equal to or greater than a number of user equipments selected from each group is skipped in the group-based greedy algorithm, and
• perform data transmission and reception with the user equipment.
