Abstract: A user terminal includes a receiving section that receives downlink control information to request feedback of transmission confirmation information for one or more downlink shared channels, and a control section that determines the number of feedback bits of the transmission confirmation information based on at least one of information related to the number of feedback bits in the downlink control information and information related to transmission timing of last downlink control information to schedule the downlink shared channel. It is possible to prevent inconsistency in understanding of the number of feedback bits of transmission confirmation information between a UE and a base station.

Abstract: A radio communication node sets a radio backhaul link with a parent node and a radio access link with a child node. The radio communication node receives control information of the radio access link, and determines location that indicates a radio resource available to the radio access based on a reception timing of the control information in a slot of a radio frame.
