Abstract

terminal comprising a control section that determines a parameter set corresponding to bit information included in the received DCI among a plurality of parameters received via RRC signalling; and a transmission section that transmits the UCI using the determined parameter set, wherein each of the plurality of parameter sets includes information indicating PUCCH format, physical resource block (PRB) index and symbol index. Also disclosed a corresponding method, base station and a system comprising the terminal and the base station.
