(canceled) ### Claim 7 A terminal comprising: a receiver that: receives, by higher layer signaling, an invalid symbol pattern indicating an invalid symbol for uplink shared channel transmission, receives first downlink control information indicating whether or not the invalid symbol pattern is applied, the first downlink control information being a downlink control information format used for scheduling or activation of an uplink shared channel, and receives second downlink control information indicating a slot format, the second downlink control information being a downlink control information format that is common to terminals; and a processor that controls, when application of the invalid symbol pattern is notified by the first downlink control information, and when different contents with respect to validity of the uplink shared channel transmission in a given symbol are notified by the invalid symbol pattern and the slot format indicated by the second downlink control information, the uplink shared channel transmission in the given symbol, based on at least one of the invalid symbol pattern and the slot format indicated by the second downlink control information. ### Claim 8 (depends on 7) The terminal according to claim 7, wherein when an uplink (UL) is configured, by the slot format indicated by the second downlink control information, for the given symbol configured invalid by the invalid symbol pattern, the processor controls not to perform the uplink shared channel transmission in the given symbol. ### Claim 9 (depends on 7) The terminal according to claim 7, wherein when a downlink (DL) is configured, by the slot format indicated by the second downlink control information, for the given symbol that is not configured invalid by the invalid symbol pattern, the processor controls not to perform the uplink shared channel transmission in the given symbol. ### Claim 10 A radio communication method for a terminal, comprising: receiving, by higher layer signaling, an invalid symbol pattern indicating an invalid symbol for uplink shared channel transmission; receiving first downlink control information indicating whether or not the invalid symbol pattern is applied, the first downlink control information being a downlink control information format used for scheduling or activation of an uplink shared channel; receiving second downlink control information indicating a slot format, the second downlink control information being a downlink control information format that is common to terminals; and when application of the invalid symbol pattern is notified by the first downlink control information, and when different contents with respect to validity of the uplink shared channel transmission in a given symbol are notified by the invalid symbol pattern and the slot format indicated by the second downlink control information, controlling the uplink shared channel transmission in the given symbol, based on at least one of the invalid symbol pattern and the slot format indicated by the second downlink control information. ### Claim 11 A base station comprising: a transmitter that: transmits, by higher layer signaling, an invalid symbol pattern indicating an invalid symbol for uplink shared channel transmission, transmits first downlink control information indicating whether or not the invalid symbol pattern is applied, the first downlink control information being a downlink control information format used for scheduling or activation of an uplink shared channel, and transmits second downlink control information indicating a slot format, the second downlink control information being a downlink control information format that is common to terminals; and a processor that controls, when application of the invalid symbol pattern is notified by the first downlink control information, and when different contents with respect to validity of the uplink shared channel transmission in a given symbol are notified by the invalid symbol pattern and the slot format indicated by the second downlink control information, reception of the uplink shared channel in the given symbol, based on at least one of the invalid symbol pattern and the slot format indicated by the second downlink control information. ### Claim 12 A system comprising a terminal and a base station, wherein the terminal comprises: a receiver that: receives, by higher layer signaling, an invalid symbol pattern indicating an invalid symbol for uplink shared channel transmission, receives first downlink control information indicating whether or not the invalid symbol pattern is applied, the first downlink control information being a downlink control information format used for scheduling or activation of an uplink shared channel, and receives second downlink control information indicating a slot format, the second downlink control information being a downlink control information format that is common to terminals; and a processor that controls, when application of the invalid symbol pattern is notified by the first downlink control information, and when different contents with respect to validity of the uplink shared channel transmission in a given symbol are notified by the invalid symbol pattern and the slot format indicated by the second downlink control information, the uplink shared channel transmission in the given symbol, based on at least one of the invalid symbol pattern and the slot format indicated by the second downlink control information, and the base station comprises: a transmitter that: transmits, by the higher layer signaling, the invalid symbol pattern, transmits the first downlink control information, and transmits the second downlink control information; and a processor that controls, when application of the invalid symbol pattern is notified by the first downlink control information, and when different contents with respect to validity of the uplink shared channel transmission in the given symbol are notified by the invalid symbol pattern and the slot format indicated by the second downlink control information, reception of the uplink shared channel in the given symbol, based on at least one of the invalid symbol pattern and the slot format indicated by the second downlink control information.
