USER TERMINAL, WIRELESS BASE STATION, AND WIRELESS COMMUNICATION METHOD

摘要

The purpose of the present invention is to inhibit a reduction in throughput, even if a wireless base station executes listen before talk (LBT), in a system operating LTE/LTE-A using carriers in which LBT is set. A user terminal according to one embodiment of the present invention is capable of communicating with a wireless base station using carriers in which LBT is set. The user terminal is characterized by being provided with: a reception unit which, on the basis of an LBT result related to a specific subframe including an LBT symbol, receives transmitted downlink data; and a control unit for controlling reception processing of the downlink data. The user terminal is further characterized in that: the specific subframe is periodically allocated, and includes the LBT symbol in the last of N symbols; a subframe which lasts a prescribed period and continues from the specific subframe includes a physical downlink control channel (PDCCH) symbol in several header symbols; and the control unit takes into account the LBT symbol and the PDCCH symbols to control the reception processing of the downlink data.
