Design of a UE-specific uplink scheduler for narrowband Internet-of-Things (NB-IoT) systems

Abstract

Narrowband internet-of things (NB-IoT) is a 3GPP standard designed for Internet-of-Things (IoT) application. This paper presents the design consideration and possible options of a UE-specific uplink (UL) scheduler for NB-IoT system. We developed a unitary C emulation platform to verify the effectiveness of the proposed approaches, which is currently under integration within the OpenAirInterface NB-IoT project.
