METHOD FOR USING TERMINAL TO DETECT SMALL-SCALE CELL IN ENVIRONMENT IN WHICH MACROCELL AND SMALL-SCALE CELL COEXIST
First Claim
1. A method for detecting a small-scale cell in a wireless communication system in which a macro cell and the small-scale cell coexist, the method performed by a user equipment which is located outside a coverage of the small-scale cell and comprising:
- performing a measurement for the macro cell;
comparing a value related to a reference signal received quality (RSRQ) obtained by the measurement for the macro cell with at least one threshold value;
determining whether to operate at least one interference removing function in order to receive a signal from the small-scale cell, according to a result of comparing the value; and
detecting the signal from the small-scale cell, if the interference removing function is operated.

Abstract
The present disclosure provides a method for using a terminal to detect a small-scale cell at the edge of coverage of the small-scale cell in a wireless communication system in which a macrocell and the small-scale cell coexist. The present invention may include: a step of measuring a macrocell; a step of comparing a value related to the reference signal received quality (RSRQ) acquired according to the macrocell measurement with at least one critical value; a step of determining whether or not to carry out at least one interference removal function for receiving a signal from a small-scale cell in accordance with the determined results; and a step of detecting the signal from the small-scale cell when the interference removal function is actuated.

6. A method for controlling a user equipment in a wireless communication system in which the macro cell and a small-scale cell coexist, the method performed by a macro cell and comprising:
-
receiving, by the macro cell, a result of a reference signal received quality (RSRQ) measurement for the macro cell itself from a user equipment which is located outside a coverage of the small-scale cell; comparing a value related to the RSRQ with at least one threshold value; and transmitting a control signal for allowing the user equipment to perform a cell reselection or a handover to the small-scale cell according to a result of comparing the value. - View Dependent Claims (7, 8, 9, 10)
