Method and apparatus of signal measurement for terminal moving at high speed in wireless communication system

A method performed by a base station in a wireless communication system, the method comprising:

• transmitting, to a terminal, information configuring a measurement scheme for a high movement speed;
• and
• receiving, from the terminal, a result of a measurement of a primary cell (PCell) and a result of a measurement of a secondary cell (SCell),
• herein the measurement of the PCell is performed based on a measurement period identified for the measurement of the PCell, the measurement period being identified based on the information configuring the measurement scheme for the high movement speed,
• wherein the measurement scheme for the high movement speed is not applied to a measurement of the SCell, and
• wherein the measurement period identified for the PCell is shorter than a measurement period for the SCell.

A terminal in a wireless communication system, the terminal comprising:

• a transceiver;
• and
• at least one processor coupled with the transceiver, and configured to:
• receive, from a base station, information configuring a measurement scheme for a high movement speed,
• identify a measurement period for a measurement of a primary cell (PCell) based on the information configuring the measurement scheme for the high movement speed, and
• perform the measurement of the PCell based on the measurement period,
• wherein the measurement scheme for the high movement speed is not applied to a measurement of a secondary cell (SCell), and
• wherein the measurement period identified for the PCell is shorter than a measurement period for the SCell.
