Abstract

The embodiment of the invention relates to a multi-cell cooperative resource allocation method based on a potential game theory. The method is provided by aiming at a wireless communication system, the interference among cooperative cells is reduced and the throughput capacity is maximized. The specific implementation method comprises the steps of taking the maximum transmission power on each same-frequency sub-channel as a constraint condition; taking maximizing the throughput capacities of all the cooperative cells as an objective function; building a utility function which takes the aim of maximizing the throughput capacities of same-frequency resource blocks on all the cooperative cells according to the traditional game theory; mapping the game problem as a complete potential game problem with a pricing factor; building a potential function which takes power distribution as an optimizing strategy; updating user channel distribution information firstly; updating power information by using an improved gradient projection law and a Jacobian iteration timing sequence according to a channel distribution result to reach a Nash equilibrium finally; and optimizing the throughput capability of the whole cooperative cells.

Description

technical field [0001] The invention relates to the field of wireless resource management, in particular to a multi-cell cooperative resource allocation method based on potential game theory. Background technique [0002] At present, users have higher and higher requirements for the content and quality of mobile communication. In order to meet the increasing service quality requirements of users, and to compete with some emerging mobile communication technologies such as WiMAX and Wi-Fi, at the end of 2004, 3GPP followed HSDPA and HSUPA After waiting for technical standards, the long-term evolution (LTE) of 3G was proposed. High speed, low delay, improved system capacity, and expanded coverage are the goals of LTE. OFDMA, as a multiple access technology for wireless links, has strict requirements on the orthogonality between sub-channels, so in the next generation mobile communication system, the interference within a cell can be ignored. At the same time, co-channel inter...
