Cross-layer optimization method for radio network resource management based on joint game

Abstract

The invention discloses a cross-layer optimization method for radio network resource management based on joint game. The method is applied in the radio network, aims at multiple radio network resources and multiple protocol stack layers, takes the correlation between the radio network resources and the protocol stack layers into consideration, and is used for integrally and reasonably optimizing the resources in radio network cells and achieving the needed optimization objective. In the involved radio network protocol stack layers, a corresponding game model is built in each layer according to the function characteristics of each layer in the involved protocol stack, the game strategy space and results in other protocol stack layers are taken into consideration when the game model in each protocol stack layer is built, the game objective of the upper protocol stack layer is set as the overall objective of the system according to the needs, and game in other protocol stack layers serves the game in the upper protocol stack layer to mainly enlarge the strategy space for the objective protocol stack layer or optimize the game objectives, thereby finally achieving the required overall optimization objective.

Description

technical field [0001] The invention belongs to the field of wireless communication, and relates to a joint game-based wireless network resource management cross-layer optimization method, in particular to a joint game idea and a wireless network resource optimization method. Background technique [0002] In the research of future wireless network resource management, due to the influence of the complex wireless communication environment, cross-layer is often used to optimize system performance from the macro perspective of the protocol stack. The cross-layer design mechanism coordinates the working process between each layer of the protocol stack by transferring specific information between each layer of the protocol stack, making it adapt to the wireless communication environment, so that the system can meet the different needs of various services. At the same time, with the development of interdisciplinary subjects in recent years, game theory has been more and more appli...

Problems solved by technology

Therefore, it is difficult to ensure that the overall performance of the system can be improved by considering only one resource.

Due to the correlation between resources at each layer, the optimization effect when considering resource optimization at a single layer is bound to be limited

[0004] (2) The layer corresponding to the research object is single. In the existing research on wireless resource management, the research objects are all the underlying resources

For example, the research on the power and frequency on the physical layer does not consider the MAC (Media Access Control, Media Access Control) layer and the RRC (Radio Resource Control, Radio Resource Control) layer; and the research on the MAC layer channel does not consider Physical layer and RRC layer

[0005] (3) When using game theory to study resource optimization, the game models under different strategy spaces are not related
