1. A method for providing an energy efficient base station with synchronization, comprising:
performing traffic analysis based on user traffic and signaling traffic at the energy efficient base station to determine off-peak hours duration when traffic is light at the energy efficient base station;
updating downlink and uplink schedulers at the energy efficient base station to transmit, at the energy efficient base station, a minimum required signaling and control information; and
wherein updating downlink and uplink scheduler for minimum required signaling and control information further comprises scheduling, in a downlink direction, at least one of transmitting only limited reference symbols over selected orthogonal frequency division multiplexing (OFDM) symbols, the limited reference symbols and selected OFDM symbols being physical downlink control channel (PDCCH) on up to a first three OFDM symbols, primary synchronization signal (PSS) and secondary synchronization signal (SSS) on a central six physical resource blocks (PRBs), and a physical broadcast channel (PBCH).
