A NOMA-Enabled Cellular Symbiotic Radio for mMTC
Wireless Personal Communications, 2021Non-orthogonal multiple access (NOMA) scheme, potentially enabling high spectral efficiency, is one of the key technological innovations in the 5th generation (5G) cellular networks. The massive machine type communications (mMTC) service category of 5G supports ultra-dense deployment of connected devices with low-power and low data-rate requirements ...

Admission Control for mMTC Traffic in 5G Networks
Proceedings of the 17th ACM Symposium on QoS and Security for Wireless and Mobile Networks, 2021Massive Machine-Type Communications (mMTC) are one of the service types supported by 5G. These are characterized by the need to serve a large number of devices that have only sporadic traffic and which have low-energy consumption. While the non-intensive nature of the traffic does not pose much strain on efficient network planning, the requirement to ...

Integrated Grant-Free Scheme for URLLC and mMTC
2020 IEEE 3rd 5G World Forum (5GWF), 2020In this paper, we study a grant-free (GF) scheme to efficiently support the IoT user equipments (UEs). Compared with the existing studies regarding the GF schemes where only one type of the IoT UEs is considered, we develop an integrated GF scheme to support both the ultra-reliable low-latency communications (URLLC) and massive machine type ...

HARQ-Based Grant-Free NOMA for mMTC Uplink
IEEE Internet of Things Journal, 2021Massive machine-type communication (mMTC) is one of the most rewarding and at the same time challenging components in the fifth-generation (5G) cellular solutions supporting the Internet of Things (IoT). The 5G mMTC is considering the use of a combination of two key mMTC enabling technologies—grant-free (GF) transmission and nonorthogonal multiple ...

Random Access Procedure for mMTC
2019In this chapter, the random access procedure for mMTC is discussed. First, the grant-based random access including the long term evolution (LTE) random access channel (RACH) is introduced. Then a suitable random access procedure for mMTC called grant-free random access is presented.
