A joint power control and access control method

Abstract

The invention aims at providing a power control-access control combined method. The power control-access control combined method is based on a Stackelberg game model, family base stations serve as leaders, macro users serve as subordinates, and after the family base stations carry out decision making on the transmitting power, the macro users can correspondingly make an access selecting decision. With the aim of maximizing the system capacity, a game is carried out between a leader layer and a subordinate layer, finally the balance state is achieved, and a transmitting power strategy of the family base stations and an access strategy of the macro users are determined. According to the power control-access control combined method, the defects of a common power control game method in a family base station network in the aspect of reducing interference in the macro users are overcome, the power control-access control combined game method is provided, and the macro users can play active roles in the aspect of improving the system overall performance.

Description

technical field [0001] The present invention relates to a joint power control and access control method, in particular to a method for transmitting power control of a home base station and access control of a macro user in a resource allocation scheme in a home base station network, and belongs to the field of communication technology. Background technique [0002] In the future, more than 50% of voice services and more than 70% of data services will take place indoors, so it is necessary to provide high-quality indoor voice and data services. With the development of wireless communication, more and more high frequency bands are used in the network to deploy wireless coverage. According to electromagnetic theory, the higher the frequency, the worse the penetration ability of radio waves. Therefore, the attenuation of high-frequency signals after passing through walls is greater, resulting in relatively poor indoor coverage quality. If the traditional method of deploying mac...

Problems solved by technology

[0007] Technical problem: The purpose of the present invention is to provide a joint power control and access control method based on game theory, which can solve the cross-layer interference existing between macro base stations and home base stations and the common layer between adjacent home base stations Even for some macro users that are far away from the macro base station and near the home base station, this method can guarantee the performance of the macro user, and the performance of the home user will not be greatly affected
