Problems solved by technology

However, there is no research related to the working mode of the base station, so there is no analysis on how to reduce the system's impact on the power grid under the conditions of ensuring the QoS of the end user (the collected energy alone provides SAP communication requirements) and network coverage (the sleep mode of the MBS). Provide energy consumption content

Embodiment Construction

[0036] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are the Some, but not all, embodiments are invented. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0037] Such as figure 1 As shown, this embodiment discloses a method for reducing energy consumption of a base station. Since there are two types of base stations, namely, a macro base station MBS and a small cell access point SAP, the method for reducing energy consumption of a base station in this embodiment includes two parts, The first part is a method for reducing...

Abstract

The invention discloses a method for reducing the energy consumption of a base station. The method is characterized by including the steps that a working mode and a power supply source of the MBS are selected according to a current MBS energy value, wherein the working mode is communication or hibernating, and the power supply source comprises a power grid and an energy collecting device; working modes and power supply sources of SAPs are selected according to current SAP energy values and numbers of the adjacent SAPs, wherein the working modes of the adjacent SAPs are communication. Compared with the prior art, the method for reducing the energy consumption of the base station has the advantages that due to selection of the base station modes based on dual-threshold judgment and the power supply sources, the consumption of the electric quantity of the power grid can be reduced under the condition that the network coverage and the QoS of terminal users are effectively guaranteed. By means of the method, the capacity of a battery for storing the energy of the power grid is further adjusted according to the activity probability of the MBS / SAP so as to achieve the further energy-saving aim.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method for reducing energy consumption of a base station. Background technique [0002] A wireless communication system, especially a base station in a wireless communication system, consumes a large amount of power grid energy to maintain normal operation. In response to the call of 5G to improve spectrum efficiency and energy efficiency, existing base station measures to reduce energy consumption include: 1. Adopt technologies to reduce energy consumption, such as base station switch control and resource allocation optimization strategies; 2. Introduce renewable energy, Such as solar energy, wind energy, etc., Macro Base Station (MBS) consumes a lot of energy. Through energy harvesting technology, renewable energy can replace part of the fixed energy consumption of MBS. It is aimed at small cells with low energy consumption in heterogeneous networks. Small cel...
