To reduce inter-cell interference in a communication system in which a base station and a terminal communicate with each other. The base station supplies uplink transmission restriction subframe configuration information indicating subframes in which the transmission of an uplink signal is restricted to the terminal. As a result of the base station setting the uplink transmission restriction subframe configuration information, the terminal restricts the transmission of an uplink signal in an uplink transmission restriction subframe which is an uplink subframe and which is a subframe indicated by the uplink transmission restriction subframe configuration information. In the uplink transmission restriction subframe, the terminal performs an operation for not transmitting an uplink signal, an operation for delaying the transmission of an uplink signal, an operation for transmitting the uplink signal which does not include a specific uplink physical channel, or an operation for transmitting the uplink signal which does not include physical channels other than a specific uplink physical channel. |
