Claim 3:
4. A base station comprising:
a receiver that receives 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, controls to receive the UCI transmitted using the uplink shared channel by puncturing an uplink data transmitted on the uplink shared channel, a transmission thereof controlled by a terminal based on a start timing of the uplink control channel, and indicates to control 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 start timing of the uplink control channel is determined 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.
