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

Abstract

The invention discloses a long-term joint optimization method of base station activation control and beamforming, the method includes: initializing a central processing unit, a network control unit, and an auxiliary processing unit in a MISO network, and the network control unit collects and processes channels in the network and Base station service status and other information, the central processing unit makes corresponding analysis according to the received current environmental information, the network control unit turns on or off the designated base station, then calculates and configures the shaped beam based on the channel information, and feeds back the power consumption indicator at the same time, assisting processing The unit receives and saves the historical data of system operation, and uses the data saved by the auxiliary processing unit to assist the central processing unit to update the weight of the neural network to assist the normal operation of the system. The invention provides an adaptive online solution, which reduces network power and solves the problems of low environmental adaptability, complicated operation, poor practicability, high operation and maintenance cost and large capital investment in the prior art.

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...
