Title:
USER TERMINAL, WIRELESS BASE STATION, AND WIRELESS COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2017/078147
Kind Code:
A1
Abstract:
In order to perform appropriate feedback of uplink control information even when the number of component carriers that can be configured for a user terminal is increased beyond existing systems, a user terminal according to one embodiment of the present invention, for which a plurality of component carriers can be configured, is characterized by having: a reception unit that receives downlink control information and/or RRC (Radio Resource Control) signaling; a transmission unit that transmits uplink control information (UCI), which includes at least delivery confirmation information, using a specified PUCCH format (PF: Physical Uplink Control Channel Format) by means of a specified resource; and a control unit that determines the specified PF and the specified resource on the basis of the payload size of at least a portion of the UCI.
