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 solutions and advantages of the present invention clearer, the present invention will be described in further 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 building a two-layer heterogeneous network: the first layer includes macro cells constructed by Ma high-power macro base stations, where 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 accurately...

Abstract

The invention provides a load-known user association method based on potential game. A heterogeneous network used by the method is composed of a macro cell constructed by Ma high-power macro base stations and a large number of randomly distributed micro base stations, a UDN is composed of a user set omega UE and a base station set omega BS, a strategy set is generated for a user at first, a user association result is initialized, the user association result is output by satisfying a potential game condition through a game model, the potential game can achieve the Nash equilibrium by maximizinga local decision function, and each user selects the maximum uu strategy solving formula and defines a user association problem. By adoption of the load-known user association method provided by theinvention, the network throughput and the load balance can be improved under the premise of satisfying the user QoS requirements, and the load-known user association method can adapt to different network requirements.

Description

technical field [0001] The present 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 the user's demand for mobile data traffic, the mobile communication system needs to expand resources from 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 macro cell coverage 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, lead...
