A method for sending signals from a base station is provided, which includes: setting an energy-saving flag when intending to enter an energy-saving mode; notifying the energy-saving mode corresponding to the energy-saving flag to a User Equipment (UE); and sending signals in the energy-saving mode applied after setting the energy-saving flag. The energy-saving flag may be a Reference Symbol (RS) energy-saving indication, data transmission bandwidth indication, or an indication of reducing antennas for sending data. When the cell load is light, the method and the energy-saving base station provided herein change the bandwidth of transmitting downlink RSs of the cell dynamically to reduce energy consumption of the base station without changing the cell bandwidth which is a critical parameter, and relieve impact on the service caused by power consumption reduction but add no complexity to the UE. |
