摘要： The present invention is designed so as to enable proper beam management (including, for example, reporting and/or indication of beams). According to the present invention, a user terminal has a receiving section that receives a downlink (DL) control channel for a first search space, and a control section that specifies a beam that is used to transmit and/or receive a DL control channel for the first search space based on associations between antenna ports of demodulation reference signals and mobility measurement signals.
