Abstract: According to one aspect of the present invention, a terminal has a receiving section that receives configuration information for multiplexing a short uplink control channel having a short time length and a long uplink control channel having a longer time length than the short uplink control channel within a predetermined period, and a control section that decides whether or not to multiplex the short uplink control channel and the long uplink control channel in the predetermined period based on the configuration information. According to one aspect of the present invention, uplink control information can be reported properly even when multiple uplink control channels of varying time lengths are used.

Abstract: The present invention is designed so that, even when a demodulation reference signal for an uplink data channel is multiplexed in a short TTI, this demodulation reference signal can be transmitted adequately. A user terminal according to one aspect of the present invention has a receiving section that receives information about the number of combs that are supported, and a control section that controls transmission of a demodulation reference signal for an uplink data channel in a second transmission time interval (TTI), which is shorter than a first TTI, and the control section maps the demodulation reference signal to a comb-shaped resource set, and maps the uplink data channel to a frequency resource of a bandwidth associated with the number of combs supported.

Abstract: A method of constructing a codebook with multiple resolution in a wireless communication system includes constructing, with a user equipment (UE), a high resolution codebook using a low resolution codebook; and transmitting, from the UE to a base station (BS), Channel State Information (CSI) feedback in accordance with a feedback scheme corresponding to the high resolution codebook or the low resolution codebook. The high resolution codebook defines the feedback scheme corresponding to the high resolution codebook. The method further comprises selecting, with the UE, multiple first beams from multiple second beams used for downlink transmission from the BS. The constructing constructs the high resolution codebook based on the multiple first beams, and the low resolution codebook is constructed based on a single beam selection scheme that selects a single beam.

Abstract: The present invention is designed so that the transmission of A/Ns can be controlled properly when the reference value for the timing for transmitting signals is controlled in radio base stations and/or user terminals. A user terminal, according to the present invention, has a receiving section that receives a downlink (DL) shared channel, and a control section that controls transmission of retransmission control information in response to the DL shared channel. The control section controls the transmission of the retransmission control information based on a reference value that is configured for timing for transmitting the retransmission control information.
