USER TERMINAL, WIRELESS BASE STATION, AND WIRELESS COMMUNICATION METHOD

摘要

The present invention is designed to enable adequate feedback on the uplink even when CA and CoMP are employed between a plurality of radio base stations (inter-eNB CoMP/CA). A receiving section that receives downlink signals from a first radio base station that forms a first cell and a second radio base station that forms a second cell, a generating section that generates a feedback signal in response to the downlink signal from each radio base station, and a control section that assigns the feedback signal in response to the downlink signal from the first radio base station to an uplink control channel and/or an uplink shared channel on the first cell depending on whether or not there is a UL grant, and assigns the feedback signal in response to the downlink signal from the second radio base station to the uplink shared channel on the first cell or the second cell regardless of whether or not there is the UL grant, are provided in a user terminal.
