Method and apparatus for signal configuration for mobile base station

A method for receiving signals from a first satellite base station and a second satellite base station, performed by a terminal, the method comprising:

• obtaining information on a first bandwidth part (BWP) of the first satellite base station that is a serving base station, and information on a second BWP of the second satellite base station;
• providing information on a current position of the terminal to the first satellite base station;
• obtaining an estimated time delay value between the terminal and the second satellite base station from the first satellite base station;
• and
• estimating a time point at which a signal of the second satellite base station arrives at the terminal based on the estimated time delay value, and monitoring the second BWP for a period within a predetermined time range from the estimated time point,
• wherein the first satellite base station and the second satellite base station transmit signals at a same time.

A timing adjustment method with a satellite base station, performed by a terminal, the timing adjustment method comprising:

• receiving, from the satellite base station, information related to a position of the satellite base station or a delay time (v) between the satellite base station and the terminal;
• when receiving the information related to the position of the satellite base station from the satellite base station, calculating the delay time (v) based on a position of the terminal and the position of the satellite base station;
• and
• transmitting a physical random access channel (PRACH) at a time (t−v) earlier by the delay time v than a configured transmission time t of the PRACH.
