Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a base station energy saving device and method. Background Art

[0002] The energy consumption of mobile networks is directly related to the operation and maintenance costs of operators. In the 4G era, the overall energy consumption (electricity costs) of the network has reached 16% of the operator's operation and maintenance costs. In mobile communication networks, energy consumption is mainly concentrated in base stations, transmission, power supply, and computer room air conditioning. Among them, base stations are the main source of energy consumption for the entire mobile communication network, accounting for more than 80% of the total network energy consumption. In the base station, the power consumption of the baseband unit (BBU) responsible for processing and calculation is relatively small, while the radio frequency unit (RRU / AAU) and cooling system consume more energy.

[0003] Traditional base station energy saving usually adopts software energy saving solutions such as subframes, channel shutdown and deep sleep. Subframe shutdown means that when the base station detects that some downlink subframes (symbols) have no data to send, it turns off the power amplifier and other RF hardware during this period to reduce static power consumption. Subframe shutdown is mainly suitable for low-load scenarios. Channel shutdown means that outdoor macro stations reduce power consumption by shutting down (or sleeping) some transmitting RF channels. Channel shutdown is mainly suitable for base station sectors with a large number of channels. Deep sleep means that the base station shuts down the AAU or RRU power amplifier, most of the RF and digital channels, and only retains the most basic digital interface circuits, so that the AAU enters a deep sleep state to reduce power consumption. Deep sleep is suitable for scenarios or time periods when 5G load is not high. Summary of the invention
