Method and apparatus for processing system information in communication system
The present disclosure relates to a pre-5 th -Generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4 th -Generation (4G) communication system such as long term evolution (LTE). Provided is a method for processing System Information (SI) by a User Equipment (UE) in a mobile communication system. The method includes receiving, from a first base station (BS), information related to change of SI; and waiting for reception of changed SI based on the information.
1. A method for processing system information (SI) by a user equipment (UE) in a wireless communication system, the method comprising:
receiving, from a first base station (BS), information indicating a change of a SI of at least one second BS and an identifier related to the at least one second BS, the at least one second BS providing dual connectivity (DC) to the UE together with the first BS;
identifying, by the UE, the change of the SI of at least one second BS based on the information; and
receiving, from the at least one second BS, the SI of the at least one second BS corresponding to the identifier.
2. A method for processing system information (SI) by a user equipment (UE) in a wireless communication system, the method comprising:
receiving, from a first base station (BS), pattern information related to a predetermined time period, wherein the pattern information is mapped to a second BS, the second BS providing dual connectivity (DC) to the UE together with the first BS;
receiving, from the first BS, first information indicating a change of a SI of the second BS within the predetermined time period, based on the pattern information; and
receiving the SI of the second BS based on the first information.
3. The method of claim 2 ,
wherein UE group comprises UEs, including the UE, connected to the second BS with the first BS,
wherein at least one another UE group comprises at least one another UEs, except to the UE, connected to at least one another second BS with the first BS, and
wherein a pattern information assigned to the UE group is different from a pattern information assigned to the at least one another UE group.
4. A user equipment (UE) for processing system information (SI) in a wireless communication system, the UE comprising:
a transceiver; and
a controller configured to control the transceiver and configured to:
receive, from a first base station(BS), information indicating a change of a SI of at least one second BS and an identifier related to the at least one second BS, the at least one second BS providing dual connectivity (DC) to the UE together with the first BS;
identify, by the UE, the change of the SI of at least one second BS based on the information; and
receive, from the at least one second BS, the SI of the at least one second BS corresponding to the identifier.
5. A user equipment (UE) for processing system information (SI) in a wireless communication system, the UE comprising:
a transceiver; and
a controller configured to control the transceiver and configured to:
receive, from a first base station (BS), pattern information related to a predetermined time period, wherein the pattern information is mapped to a second BS, the second BS providing dual connectivity (DC) to the UE together with the first BS;
receive, from the first BS, first information indicating a change of a SI of second BS within the predetermined time period, based on the pattern information; and
receive the SI of the second BS based on the first information.
6. The UE of claim 5 ,
wherein UE group comprises UEs, including the UE, connected to the second BS with the first BS,
wherein at least one another UE group comprises at least one another UEs, except to the UE, connected to at least one another second BS with the first BS, and
wherein a pattern information assigned to the UE group is different from a pattern information assigned to the at least one another UE group.
