Abstract: Methods, systems, and devices for wireless communications are described. A base station may determine to operate in accordance with an energy saving mode in which the base station only transmits remaining minimum system information (RMSI) on-demand or reduces transmission of RMSI with respect to when the base station is operating outside of the energy saving mode.
