Load balancing methods for ultra-dense network non-ideal Backhaul deployment

Abstract

Embodiments of the invention provide load balancing apparatuses and methods for ultra-dense network non-ideal Backhaul deployment. The load balancing apparatuses provided by the invention are arranged in a BS (Base Station) of a small cell, multiple BSs of the small cell are in a coverage area of a micro base station. The apparatus acquires the total throughput of users of the small cell through calculation, and compares the throughput with the non-ideal backhaul capacity of the small cell; if the throughput exceeds the backhaul capacity, the small cell does not adjust the power so as not to split users in the macro base station; if the throughput is less than the backhaul capacity, and the power of the small cell is less than the maximum transmit power, the small cell adjusts according to a determined power factor adjustment step length so as to split users in the macro base station. Base on the result of load balancing processing, the small cell splits users according to self backhaul capacity. Through adoption of the methods and apparatuses, the problem of dynamic user distribution by the small cell according to self backhaul capacity and power limitation in the existing non-ideal backhaul deployment scenario is solved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and in particular to load balancing considering non-ideal backhaul deployment in an ultra-dense network scenario in a fifth generation mobile communication system (the5thgeneration, 5G for short). Background technique [0002] The rapid development of mobile Internet and smart terminals has brought about explosive growth of mobile data services, and data traffic has shown exponential growth. These changes have sparked industry discussions on fifth-generation (5G) mobile communications. Future networks will face enormous challenges, including greater capacity, better performance, lower energy consumption, higher spectrum efficiency, and lower overhead. Ultra-dense network (UDN for short) is one of the key technologies of the fifth generation (5G) mobile communication. The dense deployment of small base stations (small cells) can improve coverage and increase the transmissi...

Problems solved by technology

In other words, if too many users are offloaded to the small base station, if the backhaul link of the small base station cannot carry the load, it will bring a large delay, and the small base station cannot meet the QoS (Quality of Service) of the user; and if the offloaded user Too little, the air interface resources and backhaul resources of the small base station cannot be effectively utilized
