USER TERMINAL, BASE STATION AND RADIO COMMUNICATION METHOD

摘要

The present invention is designed to adequately control small cells (small base stations) on/off in a structure where small cells and macro cells are arranged to overlap each other. A user terminal can communicate with a macro base station that forms a macro cell and a small base station that forms a small cell arranged within the macro cell, and has a measurement section that measures the received power of a detection/measurement signal that is transmitted from the small base station in a predetermined subframe, and the total received power of downlink signals in a subframe in which no detection/measurement signal is transmitted, a calculation section that calculates received quality by using the received power and the total received power, and a transmission section that transmits information related to the received quality to the macro base station, the calculation section calculates the received quality based on the proportion of the received power and the value given by adding the received power to the total received power.

主权项

1. A user terminal that can communicate with a macro base station that forms a macro cell and a small base station that forms a small cell arranged within the macro cell, the user terminal comprising:
a measurement section that measures received power of a detection/measurement signal that is transmitted from the small base station in a predetermined subframe, and total received power of a downlink signal in a subframe in which the detection/measurement signal is not transmitted; a calculation section that calculates received quality by using the received power and the total received power; and a transmission section that transmits information related to the received quality to the macro base station, wherein the calculation section calculates the received quality based on a proportion of the received power and a value given by adding the received power to the total received power.
