Abstract: A user terminal according to one aspect of the present disclosure includes a receiving section that receives information indicating start of report of semi-persistent channel state information (SP-CSI (Semi-Persistent Channel State Information) report), and a control section that determines timing of the SP-CSI report, based on whether or not there is relation between timing of a feedback report for reception of the information and the timing of the SP-CSI report. According to one aspect of the present disclosure, SP-CSI report and/or detection can be appropriately controlled even when SP-CSI report activation is indicated by using MAC CEs (Medium Access Control Control Elements).

Abstract: A terminal is disclosed including a receiver that receives a downlink shared channel scheduled by downlink control information; and a processor that, when the terminal is configured with a semi-statically determined first codebook and only one downlink shared channel reception is scheduled in a primary cell, controls transmission of a transmission acknowledgement signal in response to the only one downlink shared channel reception, wherein the transmission acknowledgement signal is determined from a second codebook that is different from the first codebook and corresponds only to the only one downlink shared channel. In other aspects, a radio communication method for a terminal and a base station in communication with a terminal are also disclosed.

Abstract: To properly control transmission of uplink control information by use of an uplink shared channel transmitted independently from a transmission indication from a base station. A user terminal includes a transmitting section that multiplexes uplink control information on an uplink shared channel to be transmitted independently from an uplink (UL) transmission indication from a radio base station and transmits the multiplexed resultant, and a control section that adopts a certain transmission process configured in advance regardless of the number of bits of and/or a type of the uplink control information to control transmission of the uplink control information.
