1. A communication system comprising:
a base station comprising a processor and a memory device; and
a communication terminal, comprising a processor and a memory device, and configured to perform radio communication with the base station, wherein
the base station transmits resource information related to a physical uplink control channel allocated by a symbol, the resource information including first information about an orthogonal code and second information related to a symbol number to which the physical uplink control channel is allocated, the symbol number being different from the first information about the orthogonal code and indicating a position in time domain of a symbol to which the physical uplink control channel is allocated,
the base station transmits gap information related to a gap between reception of a downlink signal and transmission of the physical uplink control channel,
the communication terminal receives the resource information and the gap information,
the communication terminal receives, from the base station, downlink control information instructing the communication terminal to use a symbol position in time domain indicated by the symbol number to transmit the physical uplink control channel,
the communication terminal transmits the physical uplink control channel using the resource information and the gap information,
the communication terminal repeats the transmission of the physical uplink control channel in two or more consecutive slots, and
the communication terminal performs the transmission of the physical uplink control channel on a same symbol position in time domain indicated by the symbol number in each of the two or more consecutive slots.
