Apparatus and method for performing paging process in wireless communication system
The present disclosure relates to a pre-5th-generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-generation (4G) communication system such as a long term evolution (LTE). A method for performing a paging process by a base station (BS) in a wireless communication system is provided. The method includes identifying that paging for a mobile station (MS) is initiated, and transmitting a paging indicator including a first part indicating a paging identifier (ID) and a second part indicating a group in which at least one MS which needs to receive a paging message is included.
1. A method for performing a paging procedure by a base station (BS) in a wireless communication system, the method comprising:
identifying that paging for a mobile station (MS) is initiated;
transmitting, to the MS, a paging indicator for scheduling a paging message, the paging indicator including both of a first part indicating a paging radio network temporary identifier (RNTI) and a second part indicating a group of MSs which need to receive the paging message; and
transmitting, to the MS, the paging message including an identifier of the MS based on the paging indicator,
wherein the first part is set to a pre-defined value, and
wherein the paging indicator is transmitted in scheduling information associated with a coverage class of the MS to be paged.
2. The method of claim 1 , wherein the first part is commonly applied to all coverage classes which are supported in the wireless communication system.
3. The method of claim 1 , wherein the second part is set to a value individually applied to each coverage class which is supported in the wireless communication system.
4. The method of claim 1 , further comprising:
receiving information of a last coverage class of the MS and the identifier of the MS.
5. The method of claim 1 , wherein the paging message is transmitted on a physical downlink shared channel (PDSCH).
6. A method for performing a paging procedure by a mobile station (MS) in a wireless communication system, the method comprising:
receiving, from a base station (BS), a paging indicator for scheduling a paging message, the paging indicator including both of a first part indicating a paging radio network temporary identifier (RNTI) and a second part indicating a group of MSs which need to receive the paging message; and
receiving the paging message including an identifier of the MS from the BS in response to identifying that the MS is included in the group indicated by the paging indicator,
wherein the first part is set to a pre-defined value, and
wherein the paging indicator is received in scheduling information associated with a coverage class of the MS to be paged.
7. The method of claim 6 , wherein the first part is commonly applied to all coverage classes which are supported in the wireless communication system.
8. The method of claim 6 , wherein the second part is set to a value individually applied to each coverage class which is supported in the wireless communication system.
9. The method of claim 6 , further comprising:
transmitting information of a last coverage class of the MS and the identifier of the MS.
10. The method of claim 6 , wherein the paging message is received on a physical downlink shared channel (PDSCH).
11. A mobile station (MS) in a wireless communication system, the MS comprising:
a transceiver; and
a processor coupled with the transceiver and configured to:
receive, from a base station (BS), a paging indicator for scheduling a paging message, the paging indicator including both of a first part indicating a paging radio network temporary identifier (RNTI) and a second part indicating a group of MSs which need to receive the paging message, and
receive the paging message including an identifier of the MS from the BS in response to identifying that the MS is included in the group indicated by the paging indicator,
wherein the first part is set to a pre-defined value, and
wherein the paging indicator is received in scheduling information associated with a coverage class of the MS to be paged.
12. The MS of claim 11 , wherein the first part is commonly applied to all coverage classes which are supported in the wireless communication system.
13. The MS of claim 11 , wherein the second part is set to a value individually applied to each coverage class which is supported in the wireless communication system.
14. The MS of claim 11 , wherein the processor is further configured to transmit information of a last coverage class of the MS and the identifier of the MS.
15. The MS of claim 11 , wherein the paging message is received on a physical downlink shared channel (PDSCH).
16. A base station (BS) in a wireless communication system, the BS comprising:
a transceiver; and
a processor coupled with the transceiver and configured to:
identify that paging for a mobile station (MS) is initiated,
transmit, to the MS, a paging indicator for scheduling a paging message, the paging indicator including both of a first part indicating a paging radio network temporary identifier (RNTI) and a second part indicating a group of MSs which need to receive the paging message, and
transmit, to the MS, the paging message including an identifier of the MS based on the paging indicator,
wherein the first part is set to a pre-defined value, and
wherein the paging indicator is received in scheduling information associated with a coverage class of the MS to be paged.
17. The BS of claim 16 , wherein the first part is commonly applied to all coverage classes which are supported in the wireless communication system.
18. The BS of claim 16 , wherein the second part is set to a value individually applied to each coverage class which is supported in the wireless communication system.
19. The BS of claim 16 , wherein the processor is further configured to:
receive information of a last coverage class of the MS and the identifier of the MS.
20. The BS of claim 16 , wherein the paging message is transmitted on a physical downlink shared channel (PDSCH).
