Related passage: Before starting of any transmission the radio bearer RB is established and all layers must are configured accordingly.The procedures for establishing radio bearers may vary according to the relation between the radio bearer and a dedicated transport channel.Depending on the QoS parameters there may or may not be a permanently allocated dedicated channel associated with the RB.
