Analysis of LTE radio parameters in different environments and transmission modes

Abstract

The ever-growing need for higher data transmission capacity drives the network service providers to build cellular Long term evolution (LTE) networks in urban areas. 3 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">rd</sup> Generation Partnership Project (3GPP) LTE is the evolution of the UMTS in response to the ever-increasing demand for high speed data and high quality multimedia broadcast services. LTE promises to deliver an unrivalled user experience with ultrafast broadband and very low latency and at the same time, a very compelling business proposition for operators with flexible spectrum bandwidth, smooth migration and the ability to deliver low cost per bit voice and data services. LTE is designed to have wider channels up to 20 MHz, with low latency and packet optimized radio access technology. The peak data rate envisaged for LTE is 100 Mbps in downlink and 50 Mbps in the uplink. LTE has many promising features like bandwidth scalability. It is developed to support both the time division duplex as well as frequency division duplex mode. This paper provides analyses of the performance of radio parameters required for efficient LTE radio planning through numerous simulations in different transmission modes and radio environments. It mainly highlights the throughput and Blok Error Rate (BLER) with respect to Signal-to-Noise Ratio (SNR) on the physical layer and in network context through different simulation environments.
