Claim 18:
19. A system for providing an energy efficient base station with synchronization, comprising:
at least one node in a core network or in a radio access network, receiving usage information from the energy efficient base station and configured to perform 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,
and to update downlink and uplink schedulers to transmit a minimum required signaling and control information; and
wherein the downlink and uplink scheduler are updated for minimum required signaling and control information, including 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).
