Abstract
Provided is a mechanism which is capable of improving wireless link quality regarding transmission from a terminal device on the ground to a non-ground station device. A terminal device including a control unit configured to acquire information regarding a type of a base station device and control a transmission timing of a signal to the base station device on the basis of the information regarding the type of the base station device.

A terminal device, comprising:
- a radio transceiver;
- and
- circuitry configured to:
- control the radio transceiver to receive System Information Block (SIB) that is broadcast from a base station device, and a Random Access Response (RAR) transmitted from the base station device, the RAR corresponds to a Random Access preamble which is transmitted from the terminal device to the base station device;
- determine whether or not the SIB contains satellite station related information;
- on condition that the SIB doesn't contain the satellite station related information, calculate a timing advance value for controlling an uplink transmission timing based on a second value, wherein a first value is not used to calculate the timing advance;
- and
- on condition that the SIB contains the satellite station related information, calculate the timing advance value based on addition of the first value to the second value, wherein
- the first value is TA_satellite which is computed based on the satellite station related information contained in the SIB and the second value is TA_normal which is contained in the received RAR.

A base station device which performs communication with a terminal device, the base station device comprising:
- a radio transceiver;
- and
- circuitry configured to control the radio transceiver to:
- broadcast System Information Block (SIB), and
- transmit a Random Access Response (RAR) corresponding to a Random Access preamble which is transmitted from the terminal device to the base station device, wherein
- on condition that the SIB doesn't contain satellite station related information, a timing advance value for controlling an uplink transmission timing from the terminal device is calculated by the terminal device based on a second value, wherein a first value is not used to calculate the timing advance,
- on condition that the SIB contains the satellite station related information, the timing advance value is calculated by the terminal device based on addition of the first value to the second value, and
- the first value is TA_satellite which is computed based on the satellite station related information contained in the SIB and the second value is TA_normal which is contained in the transmitted RAR.
