11 LOGO 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 „Requirements for Evolved UTRA (E-UTRA) and Evolved UTRAN (EUTRAN)” Alfin Hikmaturokhman.,ST.,MT11

25 LOGO OFDM Introduction 25

26 LOGO OFDM System 26  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 LOGO 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). 27

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

29 LOGO 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 29

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

34 LOGO 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. 34

35 LOGO 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. 35
