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 a double-layer non-cooperative game theory in an ultra dense network. The method comprises the following steps of setting power initial allocation values of SBSs and MUE; carrying out game according to preset pricing factors and respective game revenue functions; selecting respective game policies, namely, power allocation policies until equilibrium values arrive; setting the power initial allocation values of SUE; and carrying out power game according to the set pricing factors and the game revenue functions until the equilibrium values arrive after the SBSs obtain respective equilibrium values of the game. According to the method, the power allocation among networks can be coordinated, the interference of each layer is controlled, and moreover, the optimum power allocation set is solved effectively through the game.

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...
