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 method for managing system information (SI) window in a wireless communication system is provided. The method includes determining a plurality of SI messages to be transmitted at a time point, identifying a SI window number at the time point, and determining at least one of SI message among the plurality of SI messages, the at least one of SI message being included in a SI window corresponding to the SI window number.

First claim

The invention claimed is:

1. A method for managing a system information (SI) window in a wireless communication system, the method comprising:
determining a plurality of SI messages to be transmitted;
identifying a SI window number; and
determining at least one SI message among the plurality of SI messages, the at least one SI message being included in a SI window corresponding to the SI window number,
wherein the determining the at least one SI message comprises:
identifying a first value indicating a maximum size of SI that can be transmitted in the SI window corresponding to the SI window number,
identifying a second value indicating a size of a SI message among the plurality of SI messages,
in case that the first value is greater than the second value of a first SI message, selecting the first SI message, wherein the first SI message has a largest size among SI messages having a size smaller than the first value, and
determining that the at least one SI message comprises the first SI message.

2. The method of claim 1 , wherein a time point is a system frame number (SFN).

3. The method of claim 1 , further comprising:
identifying a third value indicating a remaining size of the SI that can be transmitted in the SI window corresponding to the SI window number, after the first SI message is included in the SI window;
selecting a second SI message, wherein the second SI message has a size smaller than the third value; and
determining that the second SI message is included in the SI window corresponding to the SI window number.

4. The method of claim 1 , further comprising:
determining at least one SI message being included in another SI window corresponding to another SI window number, after the at least one SI message included in the SI window corresponding to the SI window number is determined.

5. The method of claim 1 , wherein the SI window number is included in minimum SI or system information block 1 (SIB 1 ).

6. The method of claim 1 , wherein the at least one SI message is identified based on the SI window number, periodicity of the at least one SI message, and length of the at least one SI message.

7. An apparatus for managing a system information (SI) window in a wireless communication system, the apparatus comprising:
a transceiver; and
a controller coupled with the transceiver and configured to control to:
determine a plurality of SI messages to be transmitted,
identify a SI window number, and
determine at least one SI message among the plurality of SI messages, the at least one SI message being included in a SI window corresponding to the SI window number,

wherein the controller is further configured to:
identify a first value indicating a maximum size of SI that can be transmitted in the SI window corresponding to the SI window number,
identify a second value indicating a size of a SI message among the plurality of SI messages,
in case that the first value is greater than the second value of a first SI message, select the first SI message, wherein the first SI message has a largest size among SI messages having a size smaller than the first value, and
determine that the at least one SI message comprises the first SI message.

8. The apparatus of claim 7 , wherein a time point is a system frame number (SFN).

9. The apparatus of claim 7 , wherein the controller is further configured to:
identify a third value indicating a remaining size of a SI message that can be transmitted in the SI window corresponding to the SI window number, after the first SI message is included in the SI window;
select a second SI message, wherein the second SI message has a size smaller than the third values; and
determine that the second SI message is included in the SI window corresponding to the SI window number.

10. The apparatus of claim 7 , wherein the SI window number is included in minimum SI or system information block 1 (SIB 1 ).

11. The apparatus of claim 7 , wherein the at least one SI message is identified based on the SI window number, periodicity of the at least one SI message, and length of the at least one SI message.
