“…Multiple potential solutions have been proposed: dynamic adjustment of contention parameters (barring factor, backoff) [4], [8], load-adaptive and quality-of-service-aware RACH resource allocation [4], [9]. Also, methods for channel utilization improvement and fast collision resolution, such as tree algorithms or distributed queuing have been proposed in [3], [4]. However, all of the related works have considered only classical LTE deployment in a licensed band.…”

“…7, we show the delay vs. M dependency for an exemplary requirement of T BR = 20 s. We observe that for n < 5 Wi-Fi stations, M = 5 preambles per TXOP are sufficient, while M ≈ 40 preambles are necessary to keep T BR < T BR for n = 25. Another possible application, in a case of a controlled environment (e.g., industrial site, intraaircraft [3]), where Wi-Fi and LTE networks are operated together, our model can help answer the question of how many additional Wi-Fi stations can be added to an existing system without violating burst resolution time requirements.…”

“…While there is no clear consensus if M2M devices can be deployed in LAA or MulteFire networks, license-free band usage is possible for certain indoor M2M installation scenarios, e.g., production sites or intra-aircraft communication [1], [3]. However, M2M applications feature a massive amount of devices in a single cell, which are not supported by the currently standardized LTE systems.…”

Abstract-Next generation telecommunication systems are required to efficiently support orders of magnitude larger amount of devices per cell than the current LTE networks. This requirement is causing major design challenges for the Random Access Channel (RACH), especially for Machine-to-Machine (M2M) applications. On the other hand, due to the increasing spectrum demands, LTE vendors are exploring unlicensed spectrum. For example, MulteFire has been recently standardized as an LTEbased technology for standalone deployment in unlicensed 5GHz frequency bands. It is reasonable to expect that the coexistence with Wi-Fi and standalone LTE in the unlicensed spectrum, will amplify Random Access problem and worsen RACH performance. Henceforth, in this paper, we quantify the Wi-Fi-LTE coexistence and its impact on the RACH performance. We consider a synchronized activation of a large amount of UEs in an MulteFire/LTE unlicensed cell, and analyze the time it takes to connect all of them to the base station. Our results confirm that the presence of Wi-Fi substantially degrades RACH performance, with an increase of almost 50% per additional Wi-Fi station. Furthermore, we illustrate applications of our evaluation for RACH resource dimensioning and network planning.

Abstract-Accommodating Machine-to-Machine (M2M) applications and their requirements is one of the challenges on the way from LTE towards 5G networks. A notorious bottleneck for supporting M2M in LTE is the Random Access (RA) procedure for network connection establishment. To address the limitations of LTE RA, we introduce here the idea of Binary Contention Resolution (BCR), a simple and efficient method for prioritizing the devices during RA. Preliminary simulative evaluation shows the gains of using BCR in comparison to state-of-the-art.

The envisioned capability of machine devices to autonomously communicate in the future Internet of Things (IoT) has brought considerable attention to machine-to-machine (M2M) communication in recent years. This paradigm has applications in homes, safety, transport, health, and industry. As an active focus of research, there are interesting open questions on several of its aspects, which we aim to capture in this paper. Accompanied by an attempted classification of existing surveys on M2M, we propose a followable exposition on the challenges and open research opportunities that embrace the diverse facets of M2M communication.
