METHOD AND TERMINAL FOR PERFORMING MEASUREMENTS IN COVERAGE EXTENSION AREA OF SMALL-SCALE CELL WHEN MACRO CELL AND SMALL-SCALE CELL COEXIST

摘要

The present specification provides a method for performing measurements, by a terminal, in a coverage extension area of a small-scale cell in a wireless communication system in which macro cell and the small-scale cell coexist. The method for performing measurements can include the steps of: receiving information about a first subframe on which measurements for the small-scale cell can be performed and information about a second subframe on which measurements for the macro cell can be performed; when an interference cancellation function is set, measuring reference signal received power (RSRP) and a received signal strength indicator (RSSI) for the small-scale cell by driving the interference cancellation function on the first subframe; and measuring RSRP on the second subframe for the macro cell by driving the interference cancellation function and measuring the RSSI for the macro cell without driving the interference cancellation function.

1. A method for performing measurements in a wireless communication system in which a macro cell and a small cell coexist, the method performed by a terminal in a coverage extension area of the small cell and comprising:
receiving information of a first subframe in which the measurement for the small cell is to be performed and information of a second subframe in which the measurement for the macro cell is to be performed; measuring a reference signal received power (RSRP) and a received signal strength indicator (RSSI), by operating an interference cancellation function on the first subframe if the interference cancellation function is configured; and measuring the RSRP on the second subframe for the macro cell by operating the interference cancellation function, and measuring the RSSI by not operating the interference cancellation function.
