Long-term joint optimization method for base station activation control and beamforming

Abstract

The invention discloses a long-term joint optimization method for base station activation control and beamforming. The method comprises the following steps: initializing a central processing unit, a network control unit and an auxiliary processing unit in an MISO network; collecting and processing information such as a channel and a base station service state in the network by the network controlunit; performing corresponding analysis by the central processing unit according to the received current environment information; t opening or closing the specified base station by the network controlunit; then calculating and configuring a formed wave beam in combination with channel information, and feeding back a power consumption indication quantity; and receiving and storing historical dataof system operation by the auxiliary processing unit, assisting the central processing unit to update the neural network weight by utilizing the data stored by the auxiliary processing unit, and assist the system to normally operate. The invention provides a self-adaptive online solution, the network power is reduced, and the problems of low environmental adaptability, complex operation, poor practicability, high operation and maintenance cost and large capital investment in the prior art are solved.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a long-term joint optimization method of base station activation control and beam forming. Background technique [0002] In the context of a heterogeneous network, many different types of base stations are often arranged in a cell, and maintaining the operation of these base stations will consume a large amount of energy. Base station activation control reduces network energy consumption by shutting down service redundant operating base stations in a cell. This technology has received great attention in recent decades. Usually base station activation control and beamforming work together to enable the network to serve as many users as possible within the acceptable range of QoS. Since these problems are NP-hard (NP-hard problems mean that there is no algorithm with polynomial time to solve this problem) mixed integer programming problems, researchers o...
