Uplink and downlink decoupling single access method in heterogeneous network based on contract theory

Abstract

The invention provides an uplink and downlink decoupling single access method in a heterogeneous network based on a contract theory. The method models a decoupled single user access process as a monopoly labor market, where a base station serves as an employer, to rent a wireless resource block (including bandwidth and power) to an employee (namely user). Because the base station lacks the channelstate information of the user, a user access incentive mechanism based on the contract theory is designed for the information asymmetry. The contract is achieved by the base station giving the optimal price of the resource block to attract the user to access based on maximizing its own benefit. In addition, the feasibility of the contract is analyzed from the perspective of individual rationalityand incentive compatibility. After designing the contract, the base station broadcasts the contract, and the user chooses to sign the best contract while considering its own benefits.

Description

technical field [0001] The present invention relates to the fields of heterogeneous network user access and resource allocation, in particular to a contract theory-based uplink and downlink decoupling single access method in the heterogeneous network. Background technique [0002] Currently, the future-oriented fifth-generation mobile communication has become a global research and development hotspot. Ultra-dense networking, heterogeneity, including uplink and downlink decoupling technologies are important methods to meet 5G performance requirements. With the introduction of the above-mentioned new technologies, many basic issues in wireless communication networks need to be re-studied. The first step of radio resource management plays a very important role in implementing load balancing, interference control, and improving spectrum and energy efficiency. [0003] The analysis and design of existing user access mechanisms are almost all based on the principle of uplink and ...

Problems solved by technology

[0006] Purpose of the invention: In order to solve the technical problem that the base station lacks the user's channel state information and cannot propose reasonable resource pricing for the user due to the different uplink and downlink access base stations when the user uses decoupling for single access base station, the present invention proposes a A Single Access Method Based on Contract Theory for Uplink and Downlink Decoupling in Heterogeneous Networks
