Resource allocation method for controlling inter-cell interference in wireless communication system operating in flexible duplex mode on a cell-by-cell basis, and apparatus therefor

A base station in performing resource allocation to control inter-cell interference in a wireless communication system operating in flexible duplex mode per cell, the base station comprising:

• a transmitter;
• a receiver;
• and
• at least one processor coupled with the transmitter and the receiver,
• wherein the at least one processor is configured to:
• control the receiver to receive information on a resource only for downlink allocated for an adjacent cell having an adjacent base station belong thereto in a prescribed subframe from the adjacent base station;
• and
• allocate a resource of a cell, to which the base station belongs, corresponding to the resource only for the downlink allocated to the adjacent cell to user equipments within the base station belonging cell as a resource only for downlink based on the information on the resource,
• wherein the resource only for the downlink allocated to the base station belonging cell is allocated to a partial frequency band in a bandwidth of the prescribed subframe.
