“…In the literature, the studies [7,[9][10][11] give an overview of NB-IoT and conclude that NB-IoT can enhance bandwidth efficiency and increase network coverage. Reference [12] proposes a new procedure for cell search and initial synchronization in NB-IoT which can speed up the access operation for the devices with low SNR.…”

For 5G wireless communications, the 3GPP Narrowband Internet of Things (NB-IoT) is one of the most promising technologies, which provides multiple types of resource unit (RU) with a special repetition mechanism to improve the scheduling flexibility and enhance the coverage and transmission reliability. Besides, NB-IoT supports different operation modes to reuse the spectrum of LTE and GSM, which can make use of bandwidth more efficiently. The IoT application grows rapidly; however, those massive IoT devices need to operate for a very long time. Thus, the energy consumption becomes a critical issue. Therefore, NB-IoT provides discontinuous reception operation to save devices' energy. But, how to further reduce the transmission energy while ensuring the required ultra-reliability is still an open issue. In this paper, we study how to guarantee the reliable communication and satisfy the quality of service (QoS) while minimizing the energy consumption for IoT devices. We first model the problem as an optimization problem and prove it to be NP-complete. Then, we propose an energy-efficient, ultra-reliable, and low-complexity scheme, which consists of two phases. The first phase tries to optimize the default transmit configurations of devices which incur the lowest energy consumption and satisfy the QoS requirement. The second phase leverages a weighting strategy to balance the emergency and inflexibility for determining the scheduling order to ensure the delay constraint while maintaining energy efficiency. Extensive simulation results show that our scheme can serve more devices with guaranteed QoS while saving their energy effectively.

“…The number of additional transmissions is a minimal percentage with respect to their total number, so we can assume to ignore it. Another drawback is represented by coverage extension: coverage enhancement can be achieved by increasing the number of repetitions [9], both in the RA procedure and in data transmission over the Physical Uplink Shared Channel. This increases the amount of packets sent by UE, while the useful transmitted information remains the same.…”

Abstract-Internet of Things offers a wide spectrum of opportunities for innovative applications designed to improve our life quality. In the energy sector, the developing of smart metering networks allows operators and companies to improve the production efficiency and to offer an enhanced service to customers. 3GPP introduced in Release 13 Narrowband Internet of Things (NB-IoT) as a new cellular technology for providing wide-area coverage for Internet of Things (IoT) and Machine Type Communication (MTC). In this paper, we propose a deployment analysis of a NB-IoT system for smart metering. Estimated number of UE that this system can serve and coverage enhancement considerations with respect to LTE technology are provided.

“…Hence, a new PDCCH with a 6-RB bandwidth called the MTC-PDCCH (M-PDCCH) is specified so that a category M1 UE can decode the SIB. The second category is called the Narrowband (NB)-IoT category [34]. In this category, the transmission and reception bandwidth is 180 kHz (= 1 RB).…”
