Heterogeneous network segmentation method and system for 5G

Abstract

The invention discloses a heterogeneous network segmentation method and system for 5G. The method comprises the following steps: adopting a dual connection architecture in an ultra-dense network architecture, wherein the dual connection architecture comprises a macro base station for realizing a control function and densely-deployed wireless access nodes for realizing a data function, the macro base station is in communication connection with the densely-deployed wireless access nodes, and the control function and the data function are separately deployed on two different carriers of the dual connection architecture to achieve the separation between the control function and the data function; and decomposing the whole processing procedure of a physical layer and a medium access control layer of a 5G protocol stack into multiple corresponding sub-function modules, segmenting the whole processing procedure into a node processing procedure and a network processing procedure by taking the sub-function modules as minimum basic processing tasks aiming at the delay and capacity characteristics of forward and return links, and separately performing the processing procedures in dense node domains and network domains. The ultra-dense network with low cost, easy deployment and light maintenance can be achieved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a 5G-oriented heterogeneous network segmentation method and system. Background technique [0002] The user density of the 5G-oriented ultra-dense network will reach at least 10,000 / km2, and the average spectral efficiency of a single user can be maintained at 1.5 b / s / Hz, thereby achieving an average traffic density of 15 kb / s / Hz / km2. The access node density and user density of ultra-dense networks are of the same order of magnitude. In order to realize the dense deployment of access nodes, it is necessary to allow various types of wireless access nodes with different physical and logical characteristics to cooperate with each other and form a heterogeneous network. These nodes include both high-power nodes (such as macro stations) and low-power nodes (such as micro stations and remote radio heads). The diversity, heterogeneity and densification of nodes pose severe challenges ...
