Abstract

A micro-cell semi-cluster interference coordination method centered on user equipment, the method comprising: obtaining interference information received by user equipment to which a base station belongs; based on the obtained interference information received by user equipment to which the base station belongs, Classify the equipment and the base station; according to the classification results of the base station and the user equipment, use the semi-clustering strategy to cluster the user equipment; allocate resources to the user equipment in each cluster; when allocating resources to the user equipment in each cluster At the end, the interference information of each user equipment is updated until the total rate of the entire communication system reaches a steady state. The above solution can improve the efficiency of resource allocation in an ultra-dense network.

Description

technical field [0001] The present invention belongs to the field of communication technologies, and in particular relates to a method for coordinating interference in microcell semi-clustering with user equipment as the center. Background technique [0002] With the rapid development of Internet and Internet of Things technologies, various new business requirements continue to emerge, prompting the explosive growth of mobile data traffic in the past decade. In order to meet the requirements of higher network data transmission rate and better user data experience of future mobile communication networks, the future 5G communication technology needs to solve the above problems through a series of key technologies. In addition to increasing spectrum bandwidth and improving spectrum utilization, the most effective way is still to increase the degree of space reuse by increasing the density of cell deployment. [0003] The traditional communication system reduces the cell radius...
