Method in which a terminal connected to a cellular network measures a wireless LAN and receives information for measurement in a wireless access system, and terminal or base station device for same

A method for receiving measurement information for a second base station by a first base station in a wireless access system, the method comprising:

• transmitting activated information on the second base station to a user equipment based on the first base station in consideration of a location of the user equipment based on the first base station;
• and
• receiving measurement information for the second base station measured by the user equipment based on the first base station, using the information on the second base station,
• wherein the measurement information for the second base station is obtained based on a reference signal transmitted by the second base station, and
• wherein the reference signal transmitted by the second base station corresponds to a reference signal of the first base station, and the first base station and the second base station are heterogeneous networks.

A user equipment based on a first base station, for performing measurement for access to a second base station in a wireless access system, the user equipment comprising:

• a transmitter;
• a receiver;
• and
• a processor configured to:
• control the transmitter and the receiver,
• control the receiver to receive information on the second base station from the first base station,
• measure the second base station using the information on the second base station, and
• control the transmitter to report measurement information for the second base station to the first base station, and
• wherein the measurement for the second base station is performed based on a reference signal transmitted by the second base station, and
• wherein the reference signal transmitted by the second base station corresponds to a reference signal of the first base station, and the first base station and the second base station are heterogeneous networks.
