Method for associating user to network under small cell base station ultra-dense deployment

Abstract

The invention provides a method for associating a user to a network under small cell base station ultra-dense deployment for improving the energy efficiency of a hybrid energy heterogeneous network under ultra-dense deployment. The method comprises the following steps: firstly, a base station sets and transmits a base station weight value and a priority according to own power consumption situation; and secondly, the user perceives the use condition of green energy in an association process and preferentially accesses the base station with sufficient green energy. In the embodiment, a hybrid energy ultra-dense heterogeneous network scene in which power energy and green energy supply power at the same time is considered, modelling is performed on large-scale channel fading by using a dual-slope path loss model in 5G, and the user adaptively adjusts the association strategy according to the collection condition and use condition of the green energy of the base station. In the embodiment,the resource allocation and the transmitting power of the base station in the association process are optimized in combination with the matching theory, thereby effectively reducing the power consumption and improving the energy efficiency.

Description

technical field [0001] The present invention relates to the technical field of communication networks, in particular to a method for associating users with a network under ultra-dense deployment of small cell base stations. Background technique [0002] With the development of computer and electronic technology, communication networks have become ubiquitous, and they are also loaded with huge data traffic. According to speculation, the data traffic in 2020 will be 250 times that of 2010, which poses a huge challenge to the existing communication system. The fifth generation (5G) communication system has attracted the attention of the information and communication industry. The IMT-2020 promotion group focuses on promoting the research of key technologies in 5G. High capacity, low energy consumption, and low latency are the communication requirements in 5G. In order to realize 5G communication, ultra-dense deployment of small cell base stations in macro base stations is requ...
