Abstract: A system and method are provided to efficiently provide coverage within a large scale of a building by identifying user equipment (UE) on a floor by floor basis using a distributed antenna system (DAS) and pseudo timing advance values (TA) assigned to each floor. By applying different pseudo delays on a plurality of distributed antenna basis located at each floor, a base station can know a floor at which a user equipment is located through a timing advance value of the user equipment. When a traffic amount increases based on the measured traffic amount of each floor, the base station may increase a carrier and adjust an amplifier output on a floor by floor basis, thereby efficiently using power and maintaining a user's quality of experience (QoE).
