Embodiment Construction

[0029] The main purpose of the present invention is to provide a network energy saving method to reduce the energy consumption of base station operation.

[0030] The specific implementation of the rate splitting method proposed by the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0031] The fusion scheme of the heterogeneous wireless access network proposed by the present invention is as follows: figure 1 As shown, wireless access network 1 (WAN1) represents a cellular mobile cell with a large coverage area, and the wireless access technology it adopts is a cellular mobile multiple access technology that supports full mobility, while wireless access networks 2 and 3 ( WAN2 and WAN3) represent short-range wireless broadband access networks, which mainly provide high-speed wireless access as supplementary coverage. The scenario includes four multi-mode terminal MUEs, one macro base station MeNB (MacrocelleNB) serve...

Abstract

The invention provides an energy-saving and anti-interference speed cracking method in a cognitive heterogeneous network, which utilizes equivalent deformation of an energy efficiency equation and a cooperative game Nash axiom to carry out iteration on a transmission speed of each sub-network to obtain the optimal speed with high energy efficiency and small interference. A plurality of the sub networks are used for carrying out parallel transmission and parts of carriers of a base station do not need to be closed or blocked so that the base station can work normally. According to the method disclosed by the invention, the normal work of the base station is not changed and the quality of user experiences is guaranteed; not only can small interference be realized, namely the spectrum efficiency is high, but also energy-saving effects are realized, and the condition that iteration and convergence can be carried out in limited times can be strictly ensured.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a rate splitting method for energy saving and anti-interference in a cognitive heterogeneous network. In particular, the invention relates to methods for rate splitting using game theory. Background technique [0002] Wireless communication technology is changing with each passing day, providing various services, and these services have brought more and more convenience to people. However, while new broadband services continue to emerge, spectrum resources have become an important factor restricting their development. Worldwide, while telecom operators are accelerating the deployment of 4G LTE networks, they are all facing a major problem: the shortage of spectrum resources. According to authoritative forecasts, the 4G spectrum gap will reach 1035-1455MHz by 2020. Therefore, improving spectrum utilization becomes one of the effective solutions. The emergence of...
