Title:
USER TERMINAL, WIRELESS BASE STATION, WIRELESS COMMUNICATION METHOD, AND WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2016/017355
Kind Code:
A1
Abstract:
The purpose of the present invention is, in a system in which LTE/LTE-A are operated on unlicensed bands, to suppress the generation of UL signal interference even if a user terminal executes Listen Before Talk (LBT). A user terminal according to one embodiment of the present invention can communicate with a wireless base station using unlicensed bands, wherein the user terminal is characterized by being provided with the following: a reception processing unit that detects the channel state of an unlicensed band by carrying out LBT in a sensing subframe; and a control unit that controls a prescribed subframe as the sensing subframe on the basis of a sensing pattern.
