Abstract

The invention discloses a load-based power configuration method and device capable of reducing energy consumption of a base station, and the method and device provided by the invention are characterized in that the base station obtains a power model according to statistics, controls power configuration flow based on an automatic timer and a configuration cycle, and obtains the average load amount of the next cycle; and the transmission power corresponding to the maximum energy efficiency is calculated based on the power model of the base station and the average throughput of a cell under different transmission power, the minimum transmission power meeting data transmission is calculated based on the average load amount of the next cycle, and the maximum value of the transmission power corresponding to the maximum energy efficiency and the minimum transmission power meeting the data transmission are taken as the transmission power configured in the base station in the next cycle. The transmission power configured by utilizing the method and device provided by the invention not only ensures the data transmission of users in the cell, but also saves the energy consumption of the base station, so that the problems of the change of network topology and cavity covering brought by closing the base station can be avoided, and the energy consumed when no data is transmitted and the energy consumed when data is transmitted can be better traded off.

Description

technical field [0001] The invention belongs to the technical field of energy saving of a wireless communication system, and in particular relates to a power configuration method and a device for reducing energy consumption of a base station. Background technique [0002] Energy saving in wireless communication systems is very important to reduce operating costs and reduce energy consumption. Since the base station accounts for most of the energy consumption in the wireless communication system, reducing the energy consumption of the base station on the basis of meeting the user's quality of service requirements is the key to realizing energy saving in the wireless communication system. [0003] "Bell Labs Technical Journal" (BellLabsTechnicalJournal, vol.15, no.2, pp.77-94, Sep.2010) discloses the dynamic base station energy-saving technology, which utilizes the low-load communication capacity with a margin in the long-term scale Features, adopt the way of dynamically shut...
