Terminal, radio communication method, and base station

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.

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.

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.

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.
