Abstract:
A UE establishes an RRC connection with a base station for an application in a mobile communication network. The UE acquires a barring indication that indicates whether scheduling request (SR) barring is applicable for the application. The UE then acquires prioritized barring parameters for SR barring if applicable. The prioritized barring parameters is associated with a priority of the application. Finally, the UE determines whether to send a scheduling request for an arrived packet based on the prioritized barring parameters. In one embodiment, the application is associated with a quality of service (QoS) class indicator (QCI), and the priority of the application is based on the QCI. The prioritized SR barring mechanism based on QCI can be applied for RRC Connected mode with finer granularity.
