“…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].…”

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.

“…The approaches to resolve the RA overload problems can be categorized into PA collision mitigation [4], PUSCH resource collision avoidance [5], PUSCH resource reuse mechanism [6], [7], and access class barring (ACB) [8], [9]. Various RA schemes for access prioritization were proposed based on pricing-based load control [10] and PA allocation [11]. However, only a few studies considered the feature of stationary machine nodes in cellular RA even if there exist a lot of application scenarios deploying stationary machine nodes such as sensors and smart meters.…”

Abstract-In this paper, we propose a preamble (PA) collision resolution (PACR) scheme based on multiple timing advance (TA) values captured via tagged PAs. In the proposed PACR scheme, tags are embedded in random access (RA) PAs and multiple TA values are captured for a single detected PA during a tag detection procedure. The proposed PACR scheme significantly improves RA success probability for stationary machine nodes since the nodes using collided PAs can successfully complete the corresponding RAs using exclusive data resource blocks.

“…Moreover, centralized coordination of medium access is not possible in many scenarios, such as establishing a network connection, which is performed in a decentralized fashion [12], [13]. Connection establishment is envisioned to be the dominating part of the end-to-end delay for future NCS applications, and fast random access is one of the challenges for the evolution of wireless networks towards 5G [12], [14].…”

Abstract-Decentralized scheduling schemes offer low-cost, easy-to-install, and scalable resource allocation mechanisms suitable for networked control systems (NCS) with a large number of loops. However, contentions are unavoidable as collisions randomly occur in the communication link which lowers channel throughput and consequently compromises control performance. In this paper, we introduce a novel deterministic state-dependent prioritization policy to resolve the contention in a multi-loop NCS with random access medium. The proposed prioritization scheme can be realized within most of the shared medium technologies, e.g. ad-hoc and bus networks, aiming to decrease the collision probability. The priority for an individual control loop depends on the current local network-induced errors with a larger error leading to higher priority. We show stability of the described NCS under the proposed collision reduction mechanism according to stochastic Lyapunovbased techniques. It is demonstrated that the proposed statedependent contention resolution is considerably effective in lowering the collision rate, though incapable of eliminating it due to the decentralized nature of the medium access control.
