Abstract: A terminal is disclosed including a receiver that receives downlink control information for releasing a semi-persistent scheduling (SPS) of a downlink shared channel; and a processor, wherein if reception of no more than one unicast downlink shared channel per slot is supported by the terminal, a semi-static Hybrid automatic Repeat request Acknowledgement (HARQ-ACK) codebook is configured, and the SPS is configured, then the processor generates one HARQ-ACK bit for reception of the downlink control information. In other aspects, a radio communication method and a radio base station are also disclosed.

Abstract: A terminal is disclosed including a receiver that receives first downlink control information (DCI) indicating SRS transmission and second DCI indicating a listening condition for PUSCH transmission and a processor that, when contiguous transmissions of the SRS transmission and the PUSCH transmission are scheduled, changes the listening condition for following PUSCH transmission based on a listening result for the SRS transmission. In other aspects, a base station, a radio communication method, and a system are also disclosed.

Abstract: The present invention is designed so that, even when communication is made using a plurality of transmission time intervals (TTIs), scheduling requests are transmitted adequately. According to one aspect of the present invention, a user terminal has a transmitting/receiving section that transmits and/or receives using a plurality of transmission time intervals (TTIs) of different durations, and a control section that determines a resource to use to transmit a scheduling request (SR) based on at least one of a first TTI and a second TTI having a shorter TTI duration than the first TTI.

Abstract: The present invention is designed so that, when special subframes are allowed to transmit a PUSCH, the transmission of the PUSCH can be controlled adequately. According to the present invention, a user terminal has a receiving section that receives downlink control information (DCI) that schedules an uplink (UL) shared channel, and a control section that controls transmission of the UL shared channel by using a table that associates a subframe, in which the DCI is received, and a timing, at which the UL shared channel is transmitted, per UL/downlink (DL) configuration. The transmission timing in the table is determined based on a special subframe, which is allowed to transmit the UL shared channel, and a predetermined reference value, which is lower than 4 ms.
