Abstract

A method of wireless communication includes acquiring at least one non-required system information from a cell while in a radio resource control connected state. The non-required system information is system information that is not required in the radio resource control connected state. The method includes transitioning from the radio resource control connected state to a radio resource control idle state on the cell without acquiring the at least one non-required system information.
