Title:
A user terminal and a wireless communication method
Document Type and Number:
Japanese Patent JP6174265
Kind Code:
B2
Abstract:
In order to measure and report reception quality appropriately in a radio communication system (LAA system) supporting LBT with an unlicensed band, the present invention provides a user terminal capable of communicating with a radio base station using a first frequency carrier configured with LBT (Listen Before Talk). The user terminal has: a control section that, when a beacon reference signal of a connecting cell is detected by LBT, determines that a channel of the connecting cell is in an idle state (LBT idle ) and controls to measure reception quality in an LBT idle subframe; an obtaining section that obtains a measurement result of the reception quality in the LBT period; and a transmission section configured to transmit the measurement result.
