Embodiment Construction

[0018] The technical solution of the invention will be described in detail below in conjunction with the embodiments and the drawings of the specification:

[0019] The three-layer heterogeneous cellular network considered in the present invention is such as figure 1 , Consists of macro base stations, micro base stations and pico base stations. The parameters are λ 1 , Λ 2 , Λ 3 Homogeneous Poisson point process Φ 1 , Φ 2 , Φ 3 Represents the spatial locations of macro base stations, micro base stations, and pico base stations. The user’s location information also has a parameter λ u Homogeneous Poisson point process Φ u To represent. In order to facilitate analysis, a user is added at the origin of the coordinates to form a homogeneous Poisson point process Φ u ∪{0}, according to Slivnyak theory, the homogeneous Poisson point process Φ u And Φ u ∪{0} has the same properties. It is assumed that all base stations in the system share the same frequency spectrum, and orthogonal mu...

Abstract

The invention provides an energy-saving base station dormant method for a heterogeneous cellular network. An optimal base station dormant scheme is adopted according to the outage probability of a system and uplink transmitting power of a user. Macrocells, microcells and picocells are deployed in the poisson point process in a three-layer heterogeneous cellular network scene, and the outrage probability of the system and the uplink transmitting power of the user are derived according to a random geometric theory; a system power consumption optimization problem is solved, a part of the macrocells start a dormant state, the microcells and the picocells are added, the transmitting power of the macrocells is adjusted, and accordingly, the maximum system power consumption gain is obtained.

Description

Technical field [0001] The invention is a base station sleep solution used in a three-layer heterogeneous cellular network, and belongs to the field of mobile communication technology. Background technique [0002] With the deployment and use of 4G networks, 5G has become the research focus of the industry. In order to meet the demand for large capacity, the 5G system will be composed of multi-layer heterogeneous cellular networks of different sizes and types. However, the rapid development of communication and information technology (ICT) in recent years has directly led to the increase in the power consumption of mobile communication systems, and it also means that more carbon dioxide is produced. Therefore, how to improve while meeting the growing demand for communication services The energy efficiency of cellular heterogeneous networks has become an important issue that needs to be solved in current research. [0003] In a heterogeneous cellular network, the locations of small...
