Method and device for managing system information block, physical broadcast channel in wireless communication network
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 a system information block (SIB) in a wireless communication network.
1. A method of managing a system information block (SIB) in a wireless communication network, the method comprising:
obtaining, by a device, a primary synchronization signal (PSS) and a secondary synchronization signal (SSS) from a base station;
obtaining, by the device, information from the PSS and the SSS;
obtaining based on the information obtained from the PSS and the SSS, by the device, a frequency resource for a SIB transmitted by the base station; and
obtaining, by the device, the SIB transmitted through the frequency resource and a time resource,
wherein the information obtained from the PSS and the SSS includes a cell identity (ID) of the base station, and the frequency resource is obtained based on a function that applies modulo operation to the cell ID.
2. The method of claim 1 ,
wherein the time resource is obtained based on time related information of the SIB included in a master information block (MIB), and
wherein the SIB is transmitted through the time resource and the frequency resource.
3. The method of claim 2 , wherein the MIB is transmitted on a broadcast channel (BCH).
4. The method of claim 1 , wherein the SIB comprises at least one of time or frequency resource related information of another SIB.
5. The method of claim 1 , wherein the SIB is carried by a physical downlink shared channel (PDSCH).
6. The method of claim 5 , wherein the PDSCH is transmitted periodically in a frame.
7. A device comprising:
a communication interface configured to:
obtain, a primary synchronization signal (PSS) and a secondary synchronization signal (SSS) from a base station; and
at least one processor configured to:
obtain information from the PSS and the SSS,
obtain based on the information obtained from the PSS and the SSS, a frequency resource for a system information block (SIB) transmitted by the base station, and
obtain the SIB transmitted through the frequency resource and a time resource,
wherein the information obtained from the PSS and the SSS includes a cell identity (ID) of the base station, and the frequency resource is obtained based on a function that applies modulo operation to the cell ID.
8. The device of claim 7 ,
wherein the time resource is obtained based on time related information of the SIB included in a master information block (MIB), and
wherein the SIB is transmitted through the time resource and the frequency resource.
9. The device of claim 8 , wherein the communication interface is further configured to receive the MIB through a broadcast channel (BCH).
10. The device of claim 7 , wherein the SIB comprises at least one of time or frequency resource related information of another SIB.
11. The device of claim 7 , wherein the communication interface is further configured to receive the SIB which is carried by a physical downlink shared channel (PDSCH).
12. The device of claim 11 , wherein the PDSCH is transmitted periodically in a frame.
