Abstract
Long Term Evolution (LTE) is the fourth generation of mobile technology which was introduced in the 3GPP release 8. 4G is specifically designed for packet data communication where the emphasis is purely based on high spectral efficiency, low latency, high peak data rates and frequency flexibility. Air interface is the medium that is used for sending and receiving information between the mobile base station and user equipment (UE). The 4G mobile base station i.e. eNodeB (eNB) uses radio frames to transmit information to the UE. This paper discusses about the LTE radio frame to explore its structure and to understand its configuration for specific a UE. In order to understand the LTE frame structure we explore the various downlink channels and signals that are used to allocate physical resources for UE. Later, this paper will show a software simulation about the LTE radio frame that is transmitted by eNB over a channel which is preconfigured in the software.
