Embodiment Construction

[0076] Specific embodiments of the present invention are described in detail below, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0077] Unless expressly stated otherwise, throughout the specification and claims, the term "comprise" or variations thereof such as "includes" or "includes" and the like will be understood to include the stated elements or constituents, and not Other elements or other components are not excluded.

[0078] The present invention studies how to allocate power in a wireless network under an ultra-dense networking framework. The power allocation of the wireless network involved in this article mainly refers to the allocation of the downlink power of the macro base station in the system to each micro base station and macro cell within its coverage area according to certain rules under the network architecture of ultra-dense networking. users, and each micro base station alloc...

Abstract

The invention discloses a power allocation method based on double-layer non-cooperative game theory under ultra-dense networking, which is characterized in that it includes the following steps: setting the initial power allocation value of each SBS and MUE, and according to the preset pricing At the same time, the game is played according to their respective game revenue functions, and their respective game strategies, that is, the power allocation strategy, are selected until the equilibrium value is reached; the initial power allocation value of each SUE is set, and after the SBS obtains the equilibrium value of each game, according to The set pricing factor and game revenue function are used for power game until the equilibrium value is reached. The invention can coordinate the power distribution among various networks, and can effectively obtain the optimal power distribution set through game while controlling the interference of each layer.

Description

technical field [0001] The present invention relates to a power allocation method based on double-layer non-cooperative game theory under ultra-dense networking, specifically relates to the modeling of power allocation under ultra-dense networking, and establishes a method based on double-layer non-cooperative game theory in this scenario A power allocation model belongs to the technical field of wireless communication. Background technique [0002] In the past three decades, mobile communications have experienced a leap from voice services to mobile broadband data services. As the two main driving forces for the development of mobile communications in the future, the mobile Internet and the Internet of Things provide broad application prospects for the fifth generation of mobile communications (5G). Combining various scenarios and business requirements of the future mobile Internet and IoT, the main technical scenarios of 5G can be summarized into four scenarios: continuou...
