Abstract

Enabling a UE to determine whether the UE can skip the acquisition of SIB1-BR. An indication (e.g., a one bit flag) in the MIB is provided, which indication is set to a particular value if the UE needs to read SIB1-BR, otherwise the indication is set to a different value indicating that the UE can skip reading SIB1-BR assuming other conditions are met (e.g., assuming that the UE has previously read SIB1-BR within a MIB indication time period).
