Method and apparatus for transmitting/receiving control information for additional broadcast information in a wireless communication system
First Claim
1. A method for receiving control information for an additional broadcast message by a user equipment (UE) of a wireless communication system, the method comprising:
- receiving, by the UE from a base station (BS), control information, the control information including a system configuration descriptor (SCD) count indicating version information of a system configuration to be applied for the UE; and
receiving, by the UE from the BS, the additional broadcast message, the additional broadcast message including a system configuration information and a configuration change count indicating version information of the system configuration information,wherein the additional broadcast message is an Advanced Air Interface System Configuration Descriptor (AAI_SCD) message,wherein the SCD count included in the received control information is the same as the configuration change count included in the received additional broadcast message,wherein the BS applies the system configuration information included in the additional broadcast message,wherein, if the SCD count included in the received control information is different from a previous SCD count saved lastly at the UE and if the SCD count has not been applied yet in the UE, the UE applies a system configuration information associated with the previous SCD count saved lastly at the UE, andwherein, if the SCD count included in the received control information is different from the previous SCD count saved lastly at the UE and if the SCD count has been applied in the UE, the UE applies the system configuration information included in the received additional broadcast message.
