  10. LTE Network Alfin Hikmaturokhman.,ST.,MT

  11. Major requirements for 4G LTE • Higher peak data rates: 100 Mbps (downlink) and 50 Mbps (uplink) • Improved latency: – Radio access network latency (user plane UE – RNC - UE) below 10 ms – Significantly reduced control plane latency • Support of scalable bandwidth: 1.4, 3, 5, 10, 15, 20 MHz • Support of paired and unpaired spectrum (FDD and TDD mode) • Support for interworking with legacy networks • Cost-efficiency: – Reduced CApital and OPerational EXpenditures (CAPEX, OPEX) including backhaul – Cost-effective migration from legacy networks • A detailed summary of requirements has been captured in 3GPP TR 25.913 „Requirements for Evolved UTRA (E-UTRA) and Evolved UTRAN (EUTRAN)” Alfin Hikmaturokhman.,ST.,MT

  25. OFDM Introduction

  26. OFDM System • Pada sistem konvensional, untuk mentransmisikan data secara paralel digunakan beberapa carrier yang tidak overlap selain itu juga diperlukan guard band, hal ini tentu saja memerlukan bandwidth yang lebih lebar

  27. Contd.. • OFDM (Orthogonal Frequency Division Multiplexing) merupakan teknik modulasi multicarrier, dimana antar subcarrier saling ortogonal satu sama lain. Dengan sifat ortogonalitas ini maka antar subcarrier dapat dibuat overlapping tanpa menimbulkan efek intercarrier interference (ICI).

  28. OFDM Basics • Transmits hundreds or even thousands of separately modulated radio signals using orthogonal subcarriers spread across a wideband channel Total transmission bandwidth 15 kHzin LTE: fixed Orthogonality: The peak (centre frequency) of one subcarrier … …intercepts the ‘nulls’ of the neighbouring subcarriers

  29. Peak-to-Average Power Ratio in OFDMA • The transmitted power is the sum of the powers of all the subcarriers • Due to large number of subcarriers, the peak to average power ratio (PAPR) tends to have a large range • The higher the peaks, the greater the range of power levels over which the power amplifier is required to work • Having a UE with such a PA that works over a big range of powers would be expensive • Not best suited for use with mobile (battery-powered) devices

  30. Bentuk Sinyal SC-FDMA

  31. Tipe Sub-Carrier OFDM

  32. Channel Bandwidth Flexibility

  33. LTE frame structure consist of 1. FDD ( Frequency division duplex) 2. TDD ( Time division duplex )

  34. Generic LTE Frame Structure type 1 (FDD) • Untuk struktur generik, frame radio 10 ms dibagi dalam 20 slot yang sama berukuran 0.5 ms. • Suatu sub-frame terdiri dari 2 slot berturut-turut, sehingga satu frame radio berisi 10 sub-frame.

  35. Generic LTE Frame Structure type 2 (TDD) • Struktur frame tipe-2 hanya digunakan untuk transmisi TDD. • Slot 0 dan DwPTS disediakan untuk transmisi DL, sedangkan slot 1 dan UpPTS disediakan untuk transmisi UL.

  36. LTE Resource Block

  37. Questions LTE doesn’t supports which BW sizes? • 1.4 MHz • 5 MHz • 20 Mhz • 4 Mhz

  38. Questions LTE supports which RB sizes? 6 12 15 25 60 75 90 100 50
