CPC H04B 7/18589 (2013.01) [H04B 7/18513 (2013.01); H04W 56/0045 (2013.01); H04W 56/005 (2013.01); H04W 84/06 (2013.01)] | 12 Claims |
1. 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.
