Abstract
The present invention relates to a method including aligning a boundary of a downlink subframe from the first base station to a first user equipment with a boundary of a downlink subframe from a second base station to a second user equipment; acquiring timing advance information indicating a time by which a boundary of an uplink subframe from the first user equipment to the first base station advances compared to the aligned boundary of the downlink subframe; and notifying the first user equipment of a time point at which an uplink subframe is transmitted from the first user equipment to the first base station based on the acquired timing advance information, wherein the boundary of the uplink subframe from the notified first user equipment to the first base station is aligned with a boundary of an uplink subframe from the second user equipment to the second base station.
