5th generation (5G) systems have been designed with three main objectives in mind: increasing throughput, reducing latency, and enabling reliable communications. To meet these (often conflicting) constraints, in 2019 the 3GPP released a set of specifications for 5G NR, one of the main innovations being the support for communications in the millimeter wave (mmWave) bands. However, how to implement lower complexity, energy efficient, mid-market Internet of Things (IoT) applications is still an on-going investigation, currently led by the 3GPP which is extending the NR standard with NR-Light specifications to support devices with reduced capabilities (REDCAP). In this paper we investigate the feasibility of operating such devices at mmWaves, in view of the requirements and expectations for NR- Light applications in terms of cost and complexity, throughput, and latency. Contributions of this paper are threefold. First, we il- lustrate the potential of mmWave communication for mid-market IoT use cases. Then, we highlight and motivate the design of an NR-Light candidate interface derived from NR by a selection of features. Finally, we demonstrate the technical soundness of this interface in an industrial IoT setup via simulations.
