Fifth-generation (5G) New Radio (NR) systems are expected to support multiple traffic classes including enhanced mobile broadband (eMBB), ultra-reliable low-latency communications (URLLC), and massive machine-type (mMTC) at the same air interface. This functionality is assumed be implemented by utilizing network slicing concept. According 3rd Generation Partnership Project (3GPP), efficient of ...

For mission-critical massive machine-type communications (mMTC) applications, the messages are required to be delivered in real-time. However, due weak security protection capabilities of low-cost and low-complexity devices, active jamming attack uplink access is a serious threat. Uplink (UAJ) can increase number dropped/retransmitted packets restrict or prevent normal device access. To tackle ...

Reconfigurable intelligent surfaces (RISs) have become a promising candidate for the development of future mobile systems. In context massive machine-type communications (mMTC), RIS can be used to support transmission from group sensors collector node. Due short data packets, we focus on design maximizing weighted sum and minimum rates in finite blocklength regime. Under assumption non-orthogon...

The fifth-generation (5G) and beyond 5G (B5G) wireless networks introduced massive machine-type communications (mMTC) to cope with the growing demand of Internet Things (IoT) applications. However, heterogeneous characteristics IoT diverse quality service (QoS) requirements may lead severe interference that could degrade expected QoS cellular ecosystem. Therefore, this article studies impact ca...

Massive machine type communication (mMTC) is expected to support the connections of billion devices, where a sporadic short packet transmission key feature for mMTC applications. Conventional pilot-based coherent schemes suffer from huge resource overhead as pilot occupies large portion in transmission. To avoid and latency caused by symbols mitigate adverse effect wireless fading, we develop n...

Existing wireless communication systems have been mainly designed to provide substantial gain in terms of data rates. However, 5G and Beyond will depart from this scheme, with the objective not only services higher One main goals is support massive machine-type communications (mMTC) Internet-of-Things (IoT) applications. Supporting uplink for devices sporadic traffic pattern short-packet size, ...

Massive machine-type communications (mMTC) is one of the main services delivered by fifth Generation (5G) mobile network. The traditional cellular architecture where all devices connect to base station not energy efficient. For this reason, use device-to-device (D2D) considered reduce consumption mMTC devices. idea nearby user equipment (UE) as a relay and establish with it D2D communication. H...

The Internet of Things (IoT) application scenarios is becoming extensive due to the quick evolution smart devices with fifth-generation (5G) network slicing technologies. Hence, IoTs are significantly important in 5G/6G networks. However, communication IoT more sensitive disasters because depends on main power supply and fragile. In this paper, we consider Unmanned Aerial Vehicles (UAV) as a fl...
