Wireless communications system, base station, terminal, and process method

A base station comprising:

• a transmitting circuit configured to transmit control information to a terminal;
• and
• a control circuit configured to switch a first state of storing to the control information transmitted by the transmitting circuit, a value instructing a transmission power of the terminal, and a second state of storing to the control information, a value instructing a transmission count of multiple transmissions of a same data by the terminal.

A terminal comprising:

• a receiving circuit configured to receive control information from a base station configured to switch a first state of storing to the control information transmitted to the terminal, a value instructing a transmission power of the terminal, and a second state of storing to the control information, a value instructing a transmission count of multiple transmissions of a same data by the terminal;
• and
• a control circuit configured to switch a third state of adjusting the transmission power based on the value stored to the control information received from the base station in the first state by the receiving circuit, and a fourth state of adjusting the transmission count of multiple transmissions of the same data by the terminal, based on the value stored to the control information received from the base station in the second state by the receiving circuit.

A process method at a base station, the method comprising:

• transmitting control information to a terminal;
• and
• switching a first state of storing to the transmitted control information, a value instructing a transmission power of the terminal, and a second state of storing to the control information, a value instructing a transmission count of multiple transmissions of a same data by the terminal.

A process method at a terminal, the method comprising:

• receiving control information from a base station configured to switch a first state of storing to the control information transmitted to the terminal, a value instructing a transmission power of the terminal, and a second state of storing to the control information, a value instructing a transmission count of multiple transmissions of a same data by the terminal;
• and
• switching a third state of adjusting the transmission power based on the value stored to the control information received from the base station in the first state, and a fourth state of adjusting the transmission count of multiple transmissions of the same data by the terminal, based on the value stored to the control information received from the base station in the second state.

A wireless communications system comprising:

• a base station configured to switch a first state of storing to control information transmitted to a terminal, a value instructing a transmission power of the terminal, and a second state of storing to the control information a value instructing a period from when the terminal transmits data until retransmission of the data;
• and
• the terminal configured to switch a third state of adjusting the transmission power based on the value stored to the control information received from the base station in the first state, and a fourth state of adjusting the period from when the terminal transmits data until retransmission of the data, based on the value stored to the control information received from the base station in the second state.

A wireless communications system comprising:

• a base station configured to switch a first state of storing to control information transmitted to a terminal, a value instructing a transmission power of the terminal, and a second state of storing to the control information, a value instructing a process count of performing for a same data, a process of transmitting the same data multiple times by the terminal;
• and
• the terminal configured to switch a third state of adjusting the transmission power based on the value stored to the control information received from the base station in the first state, and a fourth state of adjusting the process count of performing for a same data, a process of transmitting the same data multiple times by the terminal.
