    摘要： According to the present invention, low-latency communication in a next-generation mobile communication system can be achieved. A user terminal includes a receiving section configured to receive at least one piece of downlink control information out of first downlink control information that schedules reception of downlink data and second downlink control information that schedules transmission of uplink data; and a control section configured to perform a control to carry out communication using a transmission time interval (TTI) configuration, including an allocation section for receiving the downlink control information, a data section for carrying out reception of downlink data corresponding to the received downlink control information and/or transmission of uplink data, and a delivery acknowledgement section for carrying out reception and/or transmission of delivery acknowledgement information corresponding to predetermined data.

    摘要： A user terminal that communicates with a plurality of cell groups (CG), each group being formed with one or more cells to use different frequency bands, and a control section that selects at least one cell, from the cells where uplink control signals can be allocated, which are configured in each CG, and controls the cell to transmit the uplink control signals. When information to indicate cross-carrier scheduling (CCS) is included in a downlink control signal, the control section decides whether or not the cell having received the downlink control signal and the cell that is designated by the information to indicate CCS belong to the same CG, and selects the cell based on this decision. Thus, the decrease of overall system performance can be reduced even when CCS and uplink control signal transmission in secondary cells are employed at the same time.

    摘要翻译： 与多个小区组（CG）进行通信的用户终端，每组由一个以上的小区构成，以使用不同的频带，以及控制部，从上行控制信号的小区中选择至少一个小区 分配，其被配置在每个CG中，并且控制小区来发送上行链路控制信号。 当在下行链路控制信号中包含用于指示跨载波调度（CCS）的信息时，控制部判定接收到下行链路控制信号的小区和由表示CCS的信息指定的小区是否属于同一 CG，并根据此决定选择单元格。 因此，即使同时使用二次电池中的CCS和上行链路控制信号传输，也可以降低总体系统性能。

    摘要： A terminal according to one aspect of the present disclosure includes a receiving section that receives information related to configuration of transmission of a plurality of physical uplink shared channels (PUSCHs) based on one piece of downlink control information (DCI), and a control section that determines, out of a plurality of reference signal indices, one or more reference signal indices used for at least one of spatial relations and pathloss reference signals (PL-RSs) for the plurality of PUSCHs. According to one aspect of the present disclosure, it is possible to appropriately control PUSCH repetition transmission even when multiple TRPs are applied.
