4th Generation: Long Term Evolution

Roadmap on 3GGP

Roadmap on 3GPP2

LTE overview


Where is the mobile industry growing?


2G Technology Evolution in 3GPP

GSM

9.6kbps (one timeslot)

GSM Data

Also called CSD

General Packet Radio Services

Data rates up to ~ 115 kbps

Max: 8 timeslots used as any one time

Packet switched; resources not tied up all the time

Contention based. Efficient, but variable delays

GSM / GPRS core network re-used by WCDMA (3G)

Enhanced Data Rates for Global Evolution

Uses 8PSK modulation

3x improvement in data rate on short distances

Can fall back to GMSK for greater distances

Combine with GPRS (EGPRS) ~ 384 kbps

Can also be combined with HSCSD


3G Technology in 3GPP

UMTS evolved from GSM via

GPRS/EDGE.

Splitting circuit switched network and

packet switched network

Data rates of UMTS are:

Rel.99 : 384 kbps/384 kbps

Rel.5 : 7.2 Mbps/384 kbps (HSDPA)

Rel.6 : 7.2 Mbps/5.8 Mbps

Rel.7 : 21 Mbps (HSPA+)


2G&3G technology in 3GPP2

IS-95B

IS-95B

Uses multiple code channels

Data rates up to 64kbps

Many operators gone direct to 1xRTT

CDMA

IS-95A

IS-95A

14.4 kbps

Core network

re-used in

CDMA2000

1xRTT

CDMA2000 1xRTT: single carrier RTT

First phase in CDMA2000 evolution

Release 0 - max 153.6 kbps

1xEV-DO

CDMA2000 1xEV-DO: Evolved Data Optimised

Third phase in CDMA2000 evolution

Standardised version of Qualcomm High Data Rate (HDR)

Adds TDMA components beneath code components

Good for highly asymmetric high speed data apps

Speeds to 2Mbps +, classed as a “3G” system

Use new or existing spectrum

1xEV-DVCDMA2000

3xRTT

CDMA2000 1x Evolved DV

Fourth phase in CDMA2000 evolution

Speeds to 9.3 Mbps+

multiplexing space-time/ frequency

block coding, switched transmit

diversity and cyclic delay diversity

Multi-layer precoded spatial

multiplexing, space-time transmit

diversity, spatial division multiple

access and beamforming.

Ups…Sorry. Since there is no

supporter this technology was

halted.


You decide!

WiMAX?

LTE?


LTE Architecture

eNB:

•User-plane : radio link cont.,

medium access cont., physical

•Control-plane: radio resources

control termination towards UE

Interface to SGW via S1

MME:

Manages and stores the UE control

plane context, Generates temporary Id

UE authentication, Authorization of TA

Mobility management

P-GW:

IP address allocation, Provide UE QoS

for GBR, Gateway to Internet

S-GW:

Gateway to UE, Anchor for

data bearer when HO, Buffers

data while the MME paging to

UE, Retains a bearer info

when UE in ECM-IDLE


LTE Latency Performance


Latency User-plane

Radio access network latency < 5 ms in unloaded condition for small IP

packet

Latency Control-plane

Transition times from idle or dormant states to active state < 100 ms

What is delay? what is latency?

Key Features (1/2)

Multiple access scheme

DL : OFDMA with CP (Cyclic Prefix)

UL : Single Carrier FDMA (SC-FDMA) with CP

Adaptive modulation and coding

DL/UL modulations : QPSK, 16QAM and 64QAM

Convolutional code and Rel-6 turbo code

Advanced MIMO spatial multiplexing techniques

(2 or 4) x (2 or 4) downlink and uplink supported

Multi-user MIMO also supported


Key Features (2/2)


Two popular techniques in MIMO wireless systems:

Spatial Diversity: Increased SNR

Receive and transmit diversity mitigates

fading and improves link quality

Spatial Multiplexing: Increased rate

Spatial multiplexing yields substantial

increase spectral efficiency

Let me ask you this question: peluang apa

saja yang bisadikembangkan oleh

mahasiswa dan Indonesia?


Challenges and Opportunities

Challenges and Opportunities

Pemerintah belum menyatakan waktu dan spektrum frekuensi

yang dialokasikan untuk LTE. Indonesia berada di antara

adopsi teknologi WiMAX dan LTE.

Layanan dan aplikasi apa saja yang sesuai dengan pipa yang

begitu besar?

Harapan pengguna, operator dan pemerintah terhadap

teknologi LTE ke depan.
