  Abstract

Open radio access network (O-RAN) is a new RAN technology that is expected to increase the flexibility of network deployment using open hardware/software (HW/SW) and open interfaces, breaking away from the traditional closed RAN structures that exclusively used equipment of certain telecommunication equipment vendors. In addition, O-RAN aims to increase the efficiency of controlling RAN nodes and managing radio resource using artificial intelligence/machine learning (AI/ML). O-RAN uses components and interfaces defined by 3rd generation partnership project (3GPP), but also newly defines its own components and interfaces. In this paper, we present the overall trend of O-RAN standardization including descriptions of components and interfaces defined by O-RAN, and present the future research direction for O-RAN.
