LTE Status in 3GPP •
LTE functional freeze has been reached, so no new
functionality to be introduced anymore in Release 8
•
RRC (Radio Resource Control) specification is the biggest
open issue in LTE specifications
•
NSN/Nokia and Vodafone introduced an action plan in
3GPP in September to ensure things are completed.
Different companies took responsibility of different areas
•
For December 2008 version most of the open issues also in
LTE RRC were solved, target freezing date for ASN.1 for
March 2009 was reached. –
Any commercial devices thus needs to be build on top of the March
2009 RRC specification (Freeze also for X2/S1 specs)
–
First feedback from 1
st
round of meetings did not reveal major
problems (that could not be solved with backwards compatible CRs)

LTE started backwards compatibility March 2009
•
Historically, it has taken 1.25-1.5 y ears from the backwards compatibility
until commercial launch with HSDPA and HSUPA
–
Note that then the basis was existing and stable Release 99

General Requirements for UTRAN Evolution Feasibility study started in 3GPP for UTRAN Long Term Evolution with the
following requirements •
Packet switched domain optimized
•
One way (radio) delay below 5 ms
•
Peak rates uplink/downlink 50/100 Mbps
•
Ensure good level of mobility and security
•
Improve terminal power efficiency
•
Frequency allocation flexibility with 1.25/2.5, 5, 10, 15 and 20 MHz
allocations, possibility to deploy adjacent to WCDMA*
•
WCDMA evolution work on-going to continue with full speed
Operators are also requiring higher radio capacity •
Depending on the case 3-4 times higher capacity expected than
with Release 6 HSDPA/HSUPA reference case
* For small bandwidths 1.4 and 3.0 MHz adopted instead

7. For internal use only

Multiple Access Selection Due to the large bandwidth, up to 20 MHz, and up to 100 Mbps data rates ->
something more than just a new modulation or larger chip rate was needed
3GPP decided in the feasibility study to use as multiple access OFDMA
(Downlink) and SC-FDMA (Uplink)
3GPP considered several alternatives •
OFDMA
•
SC-FDMA
•
And use of Multi-carrier WCDMA
•
For the downlink the choice was clear, while for the uplink a bit more
debate too place between OFDMA and SC-FDMA as especially
companies with WiMAX background preferred similarity with WiMAX.
–
SC-FDMA was also our preference (see later slides on PAR issues)
–
The chosen multiple access methods will be driven with reuse 1 like in WCDMA

OFDM benefits
Superior performance in frequency selective fading channels
Complexity of base-band receiver is much lower
Good spectral properties and handling of multiple bandwidths
Link adaptation and frequency domain scheduling
offer high potential for throughput etc gain
Other cell interference can be effectively reduced by
Interference Rejection Combining (IRC).

Windowing is needed for pulse shaping for meeting the spectrum masks •
This is even more needed if some clipping is applied (typical) in the
transmitter as that makes the spectrum wider compared to the ideal OFDM
spectrum
•

OFDM challenges
Peak-to-average ratio of the tr ansmitted signal (crest factor,
also referred in 3GPP discussions as Cubic Metric, CM)
Sensitivity to frequency error
•
This addressed by having sufficiently large sub-carrier
spacing
•
In case of too large frequency error, the sub-carriers start to
interfere each others

Why not to use OFDM in the uplink? The transmitted OFDM signal should be seen as a sum of sinusoid
This is not suited for a highly lin ear, power efficient terminal amplifier
The envelope needs to be with as low Peak-to-Average Ratio (PAR) as
possible.
Power Amplifier sees this!

Sending only one symbol at the time results to low PAR envelope •
In 3GPP Cubic Metric being considered as it represents better the
device amplifier impact than PAR
This allows to benefit from the modulation PAR/CM properties in devices
This is important for small size devices aiming for up to 23 dBm TX

The receiver is expected to
use e.g. frequency domain
equalizer •
This is simpler as ISI does
not need to be considered
due to the cyclic prefix
•
Other possibilities exists
such as Turbo equalizer
This example uses the
frequency domain generation
of the SC-FDMA signal, in
theory could be generated
without FFT as well in the
transmitter. Use of FFT
however ensures good

(FDD) The slot structure (allocation with 1 ms sub-frame resolution) has been
designed to facilitate short round trip time
With TDD there were originally two di fferent frame structures but agreement
was reached on a single TDD frame structure that is otherwise as with FDD
but some specific fields to enable also TD/SCDMA co-existence (China)

What to base the TA command on:
–
When the UE has data to transmit, implementation issue in Node B (e.g. based on

LTE Channel Quality Information (CQI) •
To enable frequency domain scheduling, one needs channel
CQI not only on the time domain (like in HSDPA) of the
expected link quality but also in the frequency domain.
•
Different combinations exists in specs, and also event and
period reporting options (-> a lot for testing) :
–
Wideband feedback (this is also always together with following
options)
ƒ
UE to report one wideband value
–
Higher Layer-configured sub-band feedback or UE selected sub-bands

Delta to configured sub-bands is signaled or in the UE selected case UE
report M best sub-bands

Cell Search Procedure •
Upon power on, UE will search for the primary synchronization
signals (3 different possibilities)
•
In Step 2 UE will determine out of each 168 values the which
of the 168 possible secondary synchronization signal is used
–
Thus total of 504 different values possible for the physical cell ID
•
The synchronization signal information is also used to
determine what kind of cell specific reference symbols are in
use in the cell to facilitate demodulation of BCH after obtaining
frequency and timing synchronization from synchronization
signals
•
After a successful BCH decoding UE may access the system
from the radio perspective (see later RACH procedure)

LTE Measurements –Carrier RSSI & RSRQ
E-UTRA Carrier Received Signal Strength Indicator, comprises the total
received wideband power observed by the UE from all sources, including
co-channel serving and non-serving cells, adjacent channel interference,
thermal noise etc.
Reference Signal Received Quality (RSRQ) is defined as the ratio
N×RSRP/(E-UTRA carrier RSSI), where Nis the number of RB’s of the
E-UTRA carrier RSSI measurement bandwidth. The measurements in the
numerator and denominator shall be made over the same set of resource
blocks.

LTE Measurements –RSRP & DL Reference Signal
Transmitted Power
Downlink reference signal transmit power is determined for a considered
cell as the linear average over the power contributions (in [W]) of the
resource elements that carry cell-s pecific reference signals which are
transmitted by the eNode B within its operating system bandwidth.
Reference signal received power (RSRP) is determined for a considered
cell as the linear average over the power contributions (in [W]) of the
resource elements that carry cell-spec ific reference signals within the
considered measurement frequency bandwidth.
If receiver diversity is in use by the UE, the reported value shall be
equivalent to the linear average of the power values of all diversity
branches.

RACH Procedure •
RACH procedure = preamble + random access response
•
Any user data or signaling data is carried on the shared data
channel. RACH does not carry data (different from WCDMA
Release 99)
•
RACH occupies 6 resource blocks in a sub-frame –
The eNode B may also schedule data in the resource blocks reserved
for random access channel preamble transmission.

TDD Multiple Access
•
In LTE TDD mode same
multiple access as in FDD
•
This is a big difference
compared to WCDMA
where TDD was totally
different
–
Some harmonization was
done e.g. chip rates and
channel coding solutions
•

LTE TDD Frame Structure TDD may change between uplink and downlink either with 5 or 10 ms period
The specific fields (DwPTS, GP, UpPTS) are inherited from TD-SCDMA •
GP = Guard Period, DwPTS/UpPTS = DL/UL pilots

TD-SCDMA co-existence with LTE TDD •
With the common frame structure (& slot) duration it is still
possible to parameterize the LTE TDD mode to operation so
that the site can have compatible uplink and downlink split
–
This would need to be rather static parameter

Differences in procedures for TDD The reason for differences procedures is the needed change
between uplink and downlink •
This impacts especially the control signaling
•
Cell search symbols (PSS and SSS) have different location
•
ACKs/NACksin one go more than in FDD (with varying
timing, see next slide)

Differences in procedures for TDD -HARQ The HARQ timing is not constant like in FDD •
This has made some combinations not feasible (like semi-
persistent scheduling + TTI bundling) in TDD.

Layer 3 (RRC) •
The Radio Resource Control (RRC) signaling is also terminated in eNodeB
(compared to RNC in WCDMA)
•
One of the enablers for the flat model is the lack of macro-diversity
•
No need for RNC like functional element -> everything radio related can
be terminated in eNodeB
•
RRC to handle: Broadcast, Paging, RRC connection management,
Mobility managements and UE measurements …

Inter Cell Interference Coordination (ICIC) •
LTE is designed for frequency reuse of one ⇒
no frequency planning required
•
Inter-site interference coordination is possible
by exchanging load information over X2
interface = soft frequency reuse
•
Options: proactive and reactive schemes
•
Simulations show no clear performance gains
from inter-site interference coordination
•
Our recommended default configuration is
frequency reuse one with flat power spectrum
and fast dynamic QoS-aware packet
scheduling

LTE Radio Resource Control (RRC) States
RRC Connected State •
UE location is known in MME
with an accuracy of a cell ID
•
The mobility of UE is handled by
the handover procedure
•
The UE performs the tracking
area update procedure
•
A signalling connection exists
between UE and MME
RRC Idle state •
No signalling connection
between UE and network exists
•
No UE context exists in E-
UTRAN
•
UE performs cell reselections

LTE UE RRC Connection Maintenance •
UE’sRRC connection can be maintained even if UE is
inactive
•
RRC connection may be released due to the following
reasons
inactive >xmin
2. High mobility: UE makes x
handovers within mminutes
1. UE is inactive for a long
time
3. Max number of RRC
connected UEs reached.

Tracking area (TA) is similar to Location/routing area in 2G/3G
•
Tracking Area Identity = MCC (Mobile Country Code), MNC (Mobile
Network Code) and TAC (Tracking Area Code)
•
When UE is in Idle, MME knows UE location with Tracking Area accuracy

LTE Handover Principles •
Lossless
–
Packets are forwarded from the source to the target
•
Network-controlled
–
Target cell is selected by the network, not by the UE
–
Handover control in E-UTRAN (not in packet core)
•
UE-assisted
–
Measurements are made and reported by the UE to the network
•
Late path switch
–
Only once the handover is successful, the packet core is involved

Data Forwarding •
Data Forwarding between source and target eNB ensures lossless
operation
•
Downlink
–
source eNB forwards all downlink RLC SDUs that have not been acknowledged
by the UE to the target eNB
–
target eNB re-transmits and prioritize all downlink RLC SDUs forwarded by the
source eNB as soon as it obtains them
–
reordering and duplication avoidance in the UE
•
Uplink
–
source eNB forwards all successfully received uplink RLC SDUs to the EPC
–
UE re-transmits the uplink RLC SDUs that have not been successfully received
by the source eNB
–
Reordering and duplication avoidance in EPC

message.
•
17. By sending RELEASE RESOURCE
the target eNB informs success of
handover to source eNB and triggers the
release of resources.
•
18. Upon reception of the RELEASE
RESOURCE message, the source eNB
can release radio and C-plane related
resources associated to the UE context.

Handover Measurement Procedure 1.
eNodeBsends Measurement control to UE giving Reporting
thresholds
2.
UE identifies others cell ids from Synchronization signal •
See earlier slides on the cell search procedure
3.
UE measures other cells’signal from Reference Symbols
(RS) •
No need to read Broadcast channel (PBCH)
4.
When the reporting threshold condition is fulfilled, UE sends
Handover measurements to eNodeB •
See earlier slides on the measurements

143. For internal use only
143 © Nokia Siemens Networks
NeighborlistGeneration in LTE •
LTE UE can detect the intra-frequency neighbors without
neighborlists⇒simpler network management
•
UE reports other cell ids to eNodeB
•
If the target cell id is known by eNodeB, it will proceed with
the handover.
•
If the target is not known by eNodeBand no is X2 enabled, 1.
eNodeB asks UE to decode Global cell id of the target cell
2.
eNodeB finds out the target cell’s IP address from O&M
3.
eNodeB enables X2 connection to the target cell
4.
eNodeB proceeds with the handover
•
2G network operators need to define the neighborlists
•
Also 3G network operators need to define the neighborlists
but it is possible for UE to detect the new cells outside
neighborlistwhich makes neighborlistcreation simpler.

Harmonization of HSPA and LTE •
HSPA and LTE have been developed by the same
standardization organization. The target has been
simple multimode implementation.
•
HSPA and LTE have in common –
Sampling rate using the same clocking frequency
–
Same kind of Turbo coding (also maximum block size close
enough)
•
The harmonization of these parameters is important
as sampling and Turbo decoding are typically done
on HW due to high processing requirements

LTE-Advanced Technologies: Relays •
The use of Relays attracts a lot
of interest in 3GPP
•
The existing specification
allows use of MBSFN sub-
frames
–
Release 8 devices are not
expecting transmission in MBSFN
sub-frame (and during which relays
can be provided with data)
•
