The future connectivity landscape and, notably, the 5G wireless systems will feature Ultra-Reliable Low Latency Communication (URLLC). The coupling of high reliability and low latency requirements in URLLC use cases makes the wireless access design very challenging, in terms of both the protocol design and of the associated transmission techniques. This paper aims to provide a broad perspective on the fundamental tradeoffs in URLLC as well as the principles used in building access protocols. Two specific technologies are considered in the context of URLLC: massive MIMO and multi-connectivity, also termed interface diversity. The paper also touches upon the important question of the proper statistical methodology for designing and assessing extremely high reliability levels.

An integrated multi‐band monopole antenna with three radiating strips having a compact structure to provide a double‐wideband operation in an Internet of Things (IoT) device is studied and presented. The proposed antenna is very suitable for the heterogeneous multi‐access network integration trend applications in mobile or fixed IoT devices, which can cover the 4G and 5G operating frequencies, the vehicle‐to‐everything and dedicated short range communication band from the IEEE 802.11p based wireless technology, the WiFi 6 band from the IEEE 802.11ax, the WLAN, and the WiMAX operating frequencies. The proposed antenna is manufactured on a single side of high quality FR4 substrate, which has a compact dimension of 8(L) × 8(W) × 0.8(T) mm3, and is composed of multibranch strips, namely, multiple curved shapes, L shapes to be embedded in the IoT device as an built‐in antenna. There are two operating bands designed between 2355‐5000 and 5112‐7000 MHz with well radiation efficiencies. The measured results show that the two operating bands are satisfied with reflection coefficient better than −6 dB, and total efficiencies of higher than 44% to 83%. In addition to that, the proposed antenna with multiband operation having a single side structure is simple to manufacture, low cost, low profile, and compact advantages.

“…An alternative solution that provides trade-off between latency and FH overhead is channel coding which can add controlled redundancy to achieve desired reliability and splits the total amount of information to transmit across different paths. Additional reliability, using any technique, sacrifies latency and hence looking at the boundaries of latency that can be offered under certain reliability is of interest to the application in-need of both [14].…”

The emerging Cloud-RAN architecture within the fifth generation (5G) of wireless networks plays a vital role in enabling higher flexibility and granularity. On the other hand, Cloud-RAN architecture introduces an additional link between the central, cloudified unit and the distributed radio unit, namely fronthaul (FH). Therefore, the foreseen reliability and latency for 5G services should also be provisioned over the FH link. In this paper, focusing on Ethernet as FH, we present a reliable packetbased FH communication and demonstrate the upper and lower bounds of latency that can be offered. These bounds yield insights into the trade-off between reliability and latency, and enable the architecture design through choice of splitting point, focusing on high layer split between PDCP and RLC and low layer split between MAC and PHY, under different FH bandwidth and traffic properties. Presented model is then analyzed both numerically and through simulation, with two classes of 5G services that are ultra reliable low latency (URLL) and enhanced mobile broadband (eMBB).
