Problems solved by technology

The method is configured to group channel quality lists having at least the same number of channel quality metric values ​​to generate grouping of channel quality lists. This method can only reflect the quality of the channel and cannot improve network throughput and load. Therefore , it is still necessary to improve the network throughput and load to meet the needs of users

Embodiment Construction

[0041] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0042] In order to describe the implementation of the present invention, consider constructing a two-layer heterogeneous network: the first layer includes macro cells constructed by Ma high-power macro base stations, wherein the macro base stations are evenly distributed, and the coverage area of ​​each macro base station can be equivalent to six polygon; the second layer is composed of a large number of randomly distributed micro base stations, the position of the micro base stations obeys the Poisson Point Process (Poisson Point Process, PPP) model, and the density is λ BS . In order to more ac...

Abstract

The present invention provides a load-known user association method based on potential game. The heterogeneous network adopted in the method is composed of macro cells constructed by Ma high-power macro base stations and a large number of randomly distributed micro base stations. UDN consists of user set Ω UE and the set of base stations Ω BS Composition, first generate a policy set for the user, initialize the user association result, and output the user association result through the game model to meet the potential game conditions. The potential game can reach the Nash equilibrium by maximizing the local decision function, and each user chooses to maximize υ u The policy solving formula of , defines the user association problem. The present invention can improve network throughput and load balancing on the premise of meeting user QoS requirements, and can adapt to different network requirements.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a user association algorithm based on a macro base station and a low-power base station. Background technique [0002] In order to meet users' demand for mobile data traffic, mobile communication systems need to expand resources in multiple dimensions such as time, frequency, space, and code, and improve resource utilization. Ultra Dense Network (Ultra Dense Network) is an effective means to make full use of space resources to improve the overall performance of mobile communication systems. The basic idea of ​​UDN is: add a large number of low-power base stations within the coverage of high-power macro base stations to supplement the lack of coverage of macro cells and increase the access volume and traffic density in the target coverage area. UDN is regarded as one of the key technologies of 5G. [0003] UDN shortens the distance between base stations, leading to increas...
