Title: USER TERMINAL AND WIRELESS COMMUNICATION METHOD
Abstract:
The present invention reduces degradation of communication performance over long TTIs, even when a short TTI inserts into a long TTI. This user terminal comprises: a reception unit that receives downlink (DL) data in a first transmission time interval (TTI); and a control unit that, when a portion of the DL data is punctured by transmission of a second TTI that is shorter than the first TTI, controls the restoration of the DL data on the basis of retransmission data that is transmitted from a wireless base station without feedback information for delivery confirmation of the DL data.
