“…This work considered only a single link and did not capture the effects of multiple users accessing the same resources. Griffith et al developed analytical and simulation models to evaluate the probability that a control packet reaches a certain number of devices assuming a particular control channel resource pool configuration [14]. In this work, multiple devices were considered but conservative assumptions were made regarding the channel effects.…”

Public safety organizations around the world started migrating toward Long-Term Evolution (LTE) networks to support the increasing needs for video and data. To address the unique voice communication requirements of first responders, the 3rd Generation Partnership Project (3GPP) introduced new capabilities that aim at providing similar functionalities as the traditional Land Mobile Radio (LMR) systems, namely, Direct Mode communication and mission critical push-to-talk (MCPTT). Direct Mode communication, also called Proximity Services (ProSe), allows public safety users to communicate directly with each other regardless of the network status. MCPTT was the first mission critical service, and first application, standardized by 3GPP to provide both on- and off-network voice capability. Assessing the performance of those capabilities is critical to accelerate their deployment and adoption by first responders. In this study, we evaluate the performance of an off-network mode MCPTT device over ProSe by focusing on the access time, a measure of the delay incurred before a user can talk. We develop analytical models for various types of calls and verify the accuracy of the predicted access time using ns-3 simulations. We perform sensitivity analysis to show the validity of the models for various scenarios. Finally, we show how the models can be used to guide parameter configuration for both MCPTT and ProSe to optimize the performance.

“…Resource scheduling for the PSCCH is beyond the scope of this study. A performance evaluation for the resource scheduling procedures in the PSCCH is presented in [3]. The remainder of this section is dedicated to the resource scheduling in the PSSCH and the D2D supported frequency hopping schemes.…”

“…The TRP selection is random from patterns with N T RP = 8 and a fixed K T RP through the scenario. The {MCS, K T RP } combination pairs {18, 1}, {10, 2}, and {6, 4} were chosen to allow 1000 bits to be transmitted over the PSSCH in every sidelink period, averaging 25 kbit/s data rate 3 . For example, a single transmission using 3 RBs with MCS 6 yields a transport block size (TBS) of 256 bits.…”

“…Due to the lack of coordination on the communication resources when the air interface is absent, direct communication can suffer from interference created by resource contending UEs. Griffith et al [3] and [4], modeled and evaluated the performance of direct communication's control and data channel, respectively, in mode 2 out-of-coverage, disclosing potential resource interference and channel inherited half duplex constrains.…”

This document presents a performance evaluation of Long Term Evolution (LTE) Deviceto-device (D2D) communication when enabling frequency hopping resource scheduling. Moreover, as secondary objective, this document serves as a compendium for frequency hopping related procedures over D2D communications as defined by The 3 rd Generation Partnership Project (3GPP) for the LTE standard. D2D communication is modeled and simulated using discrete event network simulator (ns-3). Simulated scenarios are designed to capture communication conditions occurring outside network infrastructure coverage, alike those experienced by authorized network users, such as public safety first responders, during network outages.

Cellular network technology based device-to-device communication attracts increasing attention for use cases such as the control of autonomous vehicles on the ground and in the air. LTE provides device-to-device communication options, however, the configuration options are manifold (leading to 150+ possible combinations) and therefore the ideal combination of parameters is hard to find. Depending on the use case, either throughput, reliability or latency constraints may be the primary concern of the service provider. In this work we analyze the impact of different configuration settings of unsupervised LTE deviceto-device (sidelink) communication on the system performance. Using a simulative approach we vary the length of the PSCCH period and the number of PSCCH subframes and determine the impact of different combinations of those parameters on the resulting latency, reliability and the interarrival times of the received packets. Furthermore we examine the system limitations by a scalability analysis. In this context, we propose a modified HARQ process to mitigate scalability constraints. Our results show that the proposed reduced HARQ retransmission probability can increase the system performance regarding latency and interarrival times as well as the packet transmission reliability for higher channel utilization.
