Abstract

The invention provides a cooperative game resource configuration method comprising the steps of initializing a cognitive small cell network and each parameter and state of a mobile user terminal; computing a path loss gain between each base station and a cognitive user; acquiring updated transmission power of each cognitive user; updating a sub-channel index of a small cell base station; updatingthe Lagrangian of the small cell base station via step length; updating the Lagrangian of a macro base station via the step length; performing iteration to reach the best optimization or the maximum number of iteration times; computing a utility function; and assessing the fairness of the cognitive user in the small cell network. The invention also provides a cooperative game resource configuration system of the small cell network. According to the technical scheme provided by the invention, the requirements on capacity and user fairness can be met under the premise of not reducing the qualityof service and considering incomplete CSI.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a cooperative game resource configuration method and system for a cognitive small cell network. Background technique [0002] With the rapid development of science and technology, the advent of the 5G era is not far away. In the current cellular network, it is urgent to offload services from the main macro cell, increase capacity, and enhance the coverage of indoor cell edge scenarios. In this context, deploying low-power, low-cost small cells (such as microcells, picocells, and femtocells) is a promising technology in both academia and industry. Small cells can significantly improve the efficiency of frequency reuse and spectrum sharing. [0003] However, in a heterogeneous small cell network deployed on the same frequency, cross-layer interference may be very serious. In recent years, many technical issues related to cognitive small cell networks have been studied,...
