Throughput and Delay Performance Measurements in Multi-Floor Building Employing Private LTE

Abstract

The private LTE/5G networks are now getting a lot of attention since it can offer a secure and flexible indoor network such as smart factories and buildings by the cellular-based technologies. However, the cell planning and physical layer parameter optimization to achieve the wide indoor coverage and low latency, which are important performance in such deployments, remain very important and difficult issues to be solved. Therefore, this paper measures the reference signal received power (RSRP), throughput, and delay performance with the shared extended global platform (sXGP) system following TD-LTE specification employing the 1.9 GHz band with 5 MHz bandwidth in the multi-floor building. We employ the automated guided vehicle (AGV), which enables highly accurate measurements while moving at walking speed. We measure the indoor spatial distribution of the performance under various conditions, such as opening and closing of doors and human blockage. Since the delay performance depends more on the physical layer procedure and parameter settings such as scheduling request (SR) periodicity than on the channel conditions, we evaluate the influence of the SR periodicity on the delay performance, and analyze the physical layer procedure in detail. We estimate the delay based on the analysis, and show that the estimated and the measured delays are in good agreement.

“…The third category of works focuses on the analysis of throughput/delay/loss parameters in 5G SA deployments [23]- [25]. In more detail, Rischke et al [23] perform a wide set of DL and Uplink (UL) measurement to characterize packet delay and losses in a SA campus networks.…”

“…In principle, our work differs from [23]- [25] as we focus on the impact of traffic on the exposure levels, while [23]- [25] are mainly tailored to performance assessments. However, we recognize that the methodologies adopted by [23]- [25] for the performance assessments can be potentially applied also in our framework, since the CPE is able to monitor physical layer parameters (e.g., Reference Signal Received Power (RSRP)) and to run network layer tools (ping, traceroute), which have been extensively used in the analysis of [23]- [25]. We leave the investigation of such aspects as future work.…”
