A 5G-oriented heterogeneous network segmentation method and system

Abstract

The invention discloses a 5G-oriented heterogeneous network segmentation method and system. The method includes: adopting a dual-connection architecture in an ultra-dense network architecture, and the dual-connection architecture includes a macro base station for realizing control functions and a macro base station for realizing data functions. The densely deployed wireless access nodes, the macro base station communicates with the densely deployed wireless access nodes; the control function and data function are respectively deployed on two different carriers of the dual connectivity architecture to implement control Separation of functions and data functions; the complete processing process of the physical layer and media access control layer of the 5G protocol stack is decomposed into corresponding sub-function modules, and the sub-functions are used for the delay and capacity characteristics of the fronthaul and backhaul links. The module is the minimum basic processing task, which divides the complete processing process into node processing process and network processing process, and realizes them in dense node domain and network domain respectively; it realizes an ultra-dense network with low cost, easy deployment and light maintenance.

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 ...
