LTE Introduction

What is LTE

LTE (Long Term Evolution) is known as the evolution of Radio Access

technology conducted by 3GPP.

The radio access network would evolve to E-UTRAN (Evolved

UTRAN), accompanied by the core network evolution to EPC

(Evolved Packet Core) combined as EPS

In LTE-Advanced focus is on higher capacity:

Increased peak data rate, DL 3 Gbps, UL 1.5 Gbps

Higher spectral efficiency, from a maximum of 16bps/Hz in R8 to 30

bps/Hz in R10

Increased number of simultaneously active subscribers

Improved performance at cell edges, e.g. for DL 2x2 MIMO at least

2.40 bps/Hz/cell.

Carrier Aggre

The driving force to further develop LTE towards LTEAdvanced, LTE R-10 is to provide higher bitrates i

way, and at the same time completely fulfil the requirements set by ITU for IMT Advanced, also referre

Relay Type 1 (3GPP R10):

Own Cell-ID information (viewed as a classic eNodeB from the netw

view)

Own synchronization and RS information Relay Type 2:

Share Cell-ID with Donor eNodeB (no new cell to manage from netwo

As a consequence the UE is not able to differentiate Donor and Relay

to transmit signaling/control information via Donor eNodeB and data

The performance improvement and complexity is under evaluation b
