“…Increasing bandwidth enables us to decrease the channel use time duration, or to keep the duration fixed and to increase the number of channel uses in frequency. The trade-offs arising in relation to the definition of time-frequency resources are captured in the flexible numerology used to design the 5G frames [4].…”

Ultra-reliable low latency communication (URLLC) is an important new feature brought by 5G, with a potential to support a vast set of applications that rely on mission-critical links. In this article, we first discuss the principles for supporting URLLC from the perspective of the traditional assumptions and models applied in communication/information theory. We then discuss how these principles are applied in various elements of the system design, such as use of various diversity sources, design of packets and access protocols. The important messages are that there is a need to optimize the transmission of signaling information, as well as a need for a lean use of various sources of diversity.

Unmanned aerial vehicles (UAVs), also known as drones, are proliferating. Applications such as surveillance, disaster management, and drone racing place high requirements on the communication with the drones in terms of throughout, reliability and latency. Existing wireless technologies, notably WiFi, that are currently used for drone connectivity are limited to short ranges and low-mobility situations. A new, scalable technology is needed to meet future demands on long connectivity ranges, support for fast-moving drones, and the possibility to simultaneously communicate with entire swarms of drones. Massive multiple-input and multiple-output (MIMO), a main technology component of emerging 5G standards, has the potential to meet these requirements.

“…Differently from LTE, the signalling and data fields in these frame proposals are likely to be separated in time domain, allowing the receiver to switch off when no data in addressed to it, saving energy. However, a different approach was presented in [64], where the authors propose an in-resource control signalling. The advantages of this approach are that, besides being a flexible and scalable solution, it also allows beamforming for control and data transmission and efficient time-frequency domain ICIC (inter-cell interference coordination).…”

Abstract-Existing cellular technologies are rapidly coming to their performance limits. This is due not only to the growth in data traffic and in the number of connected terminals, but also because we are on the verge of new era, where everyone and everything will be connected, with more demanding and varied requirements that cannot be satisfied by current networks. On account of this, efforts are being made all over the world to design new wireless technologies that will support the expected demands for the next decade. These technologies, embraced under the commercial name of 5 th generation, are currently being studied, and in this tutorial paper we will give an overview of the main trends that are likely to make their way in the next-generation standards.
