Abstract

The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A signal measurement method for a terminal is provided. The signal measurement method includes receiving a signal measurement indication for high-speed movement from a base station, and measuring a signal from a first cell using a measurement scheme designed for high-speed movement based on the signal measurement indication, wherein the first cell is a primary cell (PCell).

Claims

1. A method performed by a terminal in a wireless communication system, the method comprising:

receiving, from a base station, information configuring a measurement scheme for a high movement speed;

identifying 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

performing 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.

2. The method of claim 1, wherein the information is included in a system information block (SIB).

3. The method of claim 2,

wherein the measurement for the SCell is performed based on a measurement scheme other than the measurement scheme for the high movement speed,

wherein the measurement scheme for the high movement speed is not applied to a measurement of a primary SCell (PSCell), and

wherein the measurement period identified for the PCell is shorter than a measurement period for the PSCell.

4. The method of claim 1, further comprising:

transmitting, to the base station, a result of the measurement of the PCell.

5. 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.

6. The method of claim 5, wherein the information is included in a system information block (SIB).

7. The method of claim 6,

wherein the measurement for the SCell is performed based on a measurement scheme other than the measurement scheme for the high movement speed,

wherein the measurement scheme for the high movement speed is not applied to a measurement of a primary SCell (PSCell), and

wherein the measurement period identified for the PCell is shorter than a measurement period for the PSCell.

8. 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.

9. The terminal of claim 8, wherein the information is included in a system information block (SIB).

10. The terminal of claim 9,

wherein the measurement for the SCell is performed based on a measurement scheme other than the measurement scheme for the high movement speed,

wherein the measurement scheme for the high movement speed is not applied to a measurement of a primary SCell (PSCell), and

wherein the measurement period identified for the PCell is shorter than a measurement period for the PSCell.

11. The terminal of claim 8, wherein the at least one processor is further configured to transmit, to the base station, a result of the measurement of PCell.

12. A base station in a wireless communication system, the base station comprising:

a transceiver; and

at least one processor coupled with the transceiver, and configured to;

transmit, to a terminal, information configuring a measurement scheme for a high movement speed, and

receive, 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.

13. The base station of claim 12, wherein the information is included in a system information block (SIB).
