Claim 4:
5. A system comprising a terminal and a base station, wherein:
the terminal comprises:
a transmitter that transmits uplink control information (UCI) including at least one of a Hybrid Automatic Repeat reQuest-Acknowledgement (HARQ-ACK), a scheduling request (SR), and a channel state information (CSI); and
a processor that, when an uplink control channel for the UCI overlaps an uplink shared channel, punctures an uplink data transmitted on the uplink shared channel and controls to transmit the UCI by using the uplink shared channel, based on a start timing of the uplink control channel, and controls a number of resources used for the transmission of the UCI based on information related to a beta offset transmitted by radio resource control (RRC) signaling,
wherein the processor further determines the start timing of the uplink control channel based on a value of a field indicating a feedback timing of the HARQ-ACK included in a downlink control information format for scheduling a downlink shared channel; and

the base station comprises:
a receiver that receives the UCI; and
a processor that, when the uplink control channel for the UCI overlaps the uplink shared channel, controls to receive the UCI transmitted using the uplink shared channel by puncturing the uplink data transmitted on the uplink shared channel, the transmission of the UCI being controlled by the terminal based on the start timing of the uplink control channel, and indicates to control the number of resources used for the transmission of the UCI based on the information related to the beta offset transmitted by the RRC signaling.
