USER TERMINAL, WIRELESS COMMUNICATION SYSTEM, AND WIRELESS COMMUNICATION METHOD

摘要

The present invention appropriately measures and reports the receiving quality in a wireless communication system (LAA) which operates LTE in an unlicensed band. A user terminal capable of communicating with a wireless base station by using a first frequency carrier having LBT (Listen Before Talk) set therefor is equipped with: a control unit for controlling so as to measure the receiving quality in an LBTidle subframe, by recognizing that a connection cell channel is idle (LBTidle) when detecting a beacon reference signal of a connection cell by using LBT; an acquisition unit for acquiring the measurement results measuring the receiving quality during an LBT period; and a transmission unit for transmitting the measurement results.
