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...

Embodiment Construction

[0045] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0046] figure 1 It is a system network architecture diagram of the present invention. M macro users are randomly distributed within the coverage of one macro base station, there are N home base stations in a certain area within the coverage area, and there are T home users in each home base station. Macro base stations and all femto base stations use the same frequency band.

[0047] The basic idea of ​​the present invention is to apply the principle of game theory to solve the interference management in the double-layer network of the home base station, reduce cross-layer interference and common-layer interference as much as possible, optimize system resource allocation, and improve system throughput performance. First, the relationship between the power decision of the femtocell and the access decision of the macro user is modeled, and a Steinkelberg game...
