Problems solved by technology

However, in a wireless network based on the cloud radio access network (C-RAN) architecture, BBU processing energy consumption changes dynamically with the load of RRH
When the user quality of service (QoS) rate requirement is fixed, increasing the transmit power of the RRH can reduce the load of the RRH, thereby reducing the energy consumption of the BBU processing, but this will increase the energy consumption of the RRH transmission
[0004] Therefore, the energy-saving power control mechanism of the wireless network based on the C-RAN architecture needs to comprehensively consider the RRH transmission energy consumption and the BBU processing energy consumption. The traditional wireless network energy-saving power control mechanism cannot be applied to the wireless network based on the C-RAN architecture.

Abstract

The invention discloses an energy saving power control method of a wireless network based on C-RAN architecture. According to the method, RRH transmission power consumption and BBU processing energy consumption are taken into comprehensive consideration; the relation features among the RRH transmission power consumption, the BBU processing energy consumption and an RRH transmitting power are utilized; the power adjusting iterations are reduced in adoption of a criterion of preferentially adjusting the RRH with the maximum access user average signal to interference plus noise ratio; and the total energy consumption of the network is reduced as much as possible.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a power control method for energy saving of a wireless network based on a C-RAN architecture. Background technique [0002] In traditional wireless networks, energy saving has always been an important topic, and many green communication technologies have been derived. Compared with different green communication technologies, power control has been one of the most effective means to reduce energy consumption in traditional wireless networks. [0003] In a traditional wireless network, the total energy consumption of the network mainly includes the transmission energy consumption of the remote radio frequency unit (RRH) and the processing energy consumption of the baseband processing unit (BBU). However, in the existing traditional wireless network energy-saving power control mechanism, BBU processing energy consumption is generally considered to be fixed or...
