Description
Technical Field
The invention relates to the field of heterogeneous dense network systems, in particular to a method for reducing network energy consumption through base station dormancy in a heterogeneous dense network.
Background
The explosive growth of User Equipments (UEs) in 5G and the introduction of new smart devices for Multimedia Broadband Services (MBS) have resulted in a great increase in traffic. As one of the 5G new radio concepts, Ultra Dense Networks (UDNs) can meet the demand for high traffic and high traffic by densely deploying micro base stations (SBS) indoors and in hot spots to meet the demand for 1000 times of data traffic in the future. In UDNs, Macro base stations (Macro-BS) provide basic coverage, while low power micro base stations (SBS) are densely deployed within the coverage of Macro-BS.
However, densification of micro base stations greatly increases the overall energy consumption of the network, thereby reducing overall network Energy Efficiency (EE). Statistics show that densely deployed micro base stations are mostly in low traffic state and will consume 60% to 80% of the total network energy consumption in low traffic or no traffic state. A base station sleep mechanism may be employed. Namely, a proper number of low-traffic micro base stations can be shut down to reduce the static power consumption of the base stations, thereby realizing large-scale energy conservation. In addition to the large scale reduction of static power consumption, EE can be increased by improving the resource allocation method in the network. Herein, resource allocation refers to power allocation of a base station on its Resource Blocks (RBs). The power of the transmitter has a significant impact on the power consumption of the amplifier, air conditioner, etc. Therefore, the network energy consumption can be greatly reduced by intensively carrying out the sleep allocation on the base stations.
