1. A wireless communication system in which control information is capable of being transmitted, when a timing of transmitting data and a timing of transmitting the control information by a terminal overlap with each other, to a base station simultaneously with the data using a channel assigned to transmission of the data, the wireless communication system comprising:
a base station that transmits a first signal including information indicating whether the control information is able to be transmitted using the channel assigned to the transmission of the data; and
a terminal that receives the first signal including the information indicating whether the control information is able to be transmitted using the channel assigned to the transmission of the data, wherein
in a case that the timing of transmitting the data and the timing of transmitting the control information overlap with each other, the terminal transmits, when the information in the first signal indicates that the control information is not able to be transmitted using the channel, the control information to the base station using a resource other than the channel, and transmits, when the information in the first signal indicates that the control information is able to be transmitted using the channel, the control information to the base station using the channel, wherein
the information indicates, when the data is a first type having a first priority, that the control information is not able to be transmitted using the channel, and
the information indicates, when the data is a second type having a second priority that is different from the first priority, that the control information is able to be transmitted using the channel.
