The document provides an overview of High Speed Packet Data Evolution (HSPA+). It discusses the goals of HSPA+ to achieve performance comparable to Long Term Evolution (LTE) with a bandwidth of 5MHz. The key techniques discussed to achieve these goals include Multiple Input Multiple Output (MIMO), higher order modulation up to 64QAM, control channel improvements, and protocol optimizations. In conclusion, the combination of these techniques allows HSPA+ to reach close to LTE performance targets, though some targets like lower latency may not be achievable due to the longer transmission time interval of HSPA+.

6. INTRODUCTION
& HISTORY
• HIGH SPEED PACKET DATA EVOLUTION IS ALSO KNOWN AS HSPA+.
• HSPA+ IS A WIRELESS BROADBAND STANDARD DEFINED IN 3GPP
RELEASE 7 AND ABOVE.
• .
• THE 84 MBPS AND 22 MBPS REPRESENT THEORETICAL PEAK SECTOR
SPEEDS.
• THE ACTUAL SPEED FOR USER WILL BE LOWER.AT CELL EDGE AND
EVEN AT HALF THE DISTANCE TO THE CELL EDGE THERE MAY ONLY BE
SLIGHT INCREASE COMPARED WITH 14.4 MBPS.

7. INTRODUCTION
& HISTORY
• THE DEMANDS OF PACKET DATA APPS. HAVE RESULTED IN SEVERAL
IMPROVEMENTS OVER THE ORIGINAL WCDMA RELEASE 99.
• THE DOWNLINK WAS IMPROVED IN RELEASE 5 WITH HSPDA
,WHICH PROVIDED HIGH SPEED SHARED CHANNEL WITH FAST LINK
ADAPTATION & SCHEDULING , HYBRID ARQ , SHORT 2 ms TTI , AND
FAST INTER-CELL INTERFERENCE SUPRESSION.
• RECENTLY WORK HAS STARTED TO EVOLVE THE UTRAN WITH LONG
TERM EVOLUTION(LTE), PROVIDING A NEW AIR INTERFERENCE.
• LTE WILL BE SUPPORTING FLEXIBLE SPECTRUM ALLOCATION 1.5MHz
AND UPTO 20MHz, AND PROVIDE SIGNIFICANT PERFORMANCE
IMPROVEMENTS IN APPLICATION PERFORMANCE AND SYSTEM
CAPACITY.

8. • FOR OPERATORS WITH EXISTING HSPA DEPLOYMENT, THE
POSSIBILITY TO EVOLVE HSPA SHOULD PROVIDE AN EASY WAY TO
UPDATE THE SYSTEM.
• FOR THIS REASON WORK ON HSPA EVOLUTION HAS STARTED IN
3GPP.IN THIS SEMINAR ,THE MAIN TECHNOLOGIES ARE USED TO
EVOLVE THE HSPA SYSTEM, COMPARE THE REACHABLE
PERFORMANCE TO THE PERFORMANCE GOALS OF THE LTE IN 5MHz
BANDWIDTH, AND SUMMARIZE THE CONCEPT OF HSPA+.
• IN THIS SEMINAR,THE COLLECTION OF THE VARIOUS INDIVIDUAL
IMPROVEMENTS PROVIDES A COMPREHENSIVE OVERVIEW OF HSPA+.
INTRODUCTION
& HISTORY

9. PERFORMANCE GOALS
• THE PERFORMANCE GOALS FOR LTE OF UTRAN HAVE BEEN
AGREED UPON IN 3GPP AND ARE SUMMARIZED IN TABLE 1.

10. PERFORMANCE GOALS
• LTE SHOULD WORK WITH HIGH MOBILITY ,
PROVIDE LARGE COVERAGE ,ALLOW FLEXIBLE
SPECTRUM ALLOCATION,EASY MIGRATION,
AND CO-EXISTANCE WITH EARLIER UTRAN
RELEASE.
• THE PERFORMANCE OF HSPA+ SHOULD TARGET
LTE PERFORMANCE WITH TWO MAJOR
DIFFERENCE:1. THE BANDWIDTH IS LIMITED TO
5MHz, 2. THE TRANSMISSION TIME INTERVAL IS
2 ms TO 1ms FOR LTE.
• THE LONGER TTI WILL NOT ALLOW HSPA+ TO
REACH USER PLANE LATENCY TARGET OF LTE.

14. TECHNIQUES
• IN THIS ,ANSWERS WILL BE GIVEN TO ACHIEVE TARGETS THAT
HAVE BEEN SET FOR PERFORMANCE.
• 1 MIMO:-
• INCREASING DATA RATE CAN BE ACHIEVED BY TRANSMITTING
MULTIPLE PARALLEL TRANSPORT TO A SINGLE USER.THIS IS
OFTEN REFERRED TO AS MULTIPLE INPUT MULTIPLE
OUTPUT.
• THE PREFERRED USE FOR CHANNELS WITH FAVOURABLE
CORRELATION PROPERTIES E.G SMALL CELLS OR INDOOR
DEPLOYMENT.
• THE RECEIVER HAS THE POSSIBILITY TO SEPARATE THE
MULTIPLE DATA STREAMS BY USING TH CHANNEL PROPERTIES
AND KNOWLEDGE OF CODING SCHEME.
• IN ORDER FOR THE RECEIVERS TO SOLVE THIS TASK IT IS
NECESSARY TO STANDARDIZE THE USED MULTI-LAYER
TRANSMISSION SCHEME.

15. • THE LINK ADAPTION IS A MIX OF SPATIAL AND
TEMPORAL ADAPTION.FOR EACH TTI ,OR RATHER AT A
RATE SET BY THE NETWORK .
• TO INFORM THE UE ABOUT THE ACTUAL PARAMETERS
OF A TRANSMISSION , THE DOWNLINK CONTROL
CHANNEL HS-SCCH , HAS BEEN ADAPTED TO
INCORPORATE MIMO INFORMATION.
• AT EACH TTI , WHEN A PERTICULAR USER IS
SCHEDULED ,THE NODE-B INCLUDES THE USED PRE-
CODING WEIGHT,THE NUMBER OF STREAMS AND THE
MODULATION USED ON EACH STREAM TO THE FIRST
PART OF THE HS-SCCH.
TECHNIQUES

16. TECHNIQUES
• IN ORDER TO INTRODUCE MIMO, THE UPLINK
SIGNALING HAS BEEN MODIFIED SLIGHTLY .THE
RELEASE 5/6 HS-DPCCH HAS BEEN EXPANDED TO
ACCOMMODATE THE NEW MIMO SIGNALING.
• SINCE TWO TRANSPORT BLOCKS CAN BE
TRANSMITTED ,EACH WITH ITS OWN HARQ PROCESS
,THE HARQ ACK/NACK FIELD OF THE HS-DPCCH HAS
TO BE EXPANDED TO ACCOMMODATE SIGNALING FOR
THE SECOND STREAM.
• IN RELEASE 5/6 THE ACK BIT IS REPEATED TO 10
BITS.FOR, MIMO PURE REPETITION WOULD GIVE A
CODE WITH HAMMING DISTANCE 5. HOWEVER ,IF THE
ACK/NACK IS JOINTLY ENCODED ,A CODE WITH
HAMMING DISTANCE 6 CAN BE FOUND.

17. TECHNIQUES
• THE CQI EVOLUTION IS SLIGHTLY
MODIFIED COMPARED TO RELEASE 5.
THE MAIN REASON FOR THIS IS THE
CODE-REUSE INTERFERENCE TERM THAT
IS PRESENT WHEN TRANSMITTING TWO
STREAMS.
• SINCE THE TERM WILL BE DEPENDENT
ON THE ACTUAL CHANNEL
REALIZATION AND CODE ALLOCATION ,
ONLY THE UE CAN ESTIMATE THE
INFLUENCE ON THE EXPERIENCED SINR.

18. Higher order modulation
• HSPA systems support the use of 16QAM
in the downlink and QPSK in the uplink.
• HSPA+ use 64QAM in the downlink and
16QAM in the uplink.
• High SNR
• QPSK modulation SNR=14.5db
• 64-QAM SNR=22.5db

19. QPSK

20. 16-QAM

26. Continuous Packet Connectivity
• Discontinuous transmission and reception
can be applied in either uplink or in downlink.
• The downlink discontinuous reception will
allow the UE to enter power saving mode
• The uplink discontinuous transmission will
only impact the transmission of the power
control commands. At any point of the time,
the UE is able to transmit higher layer data
(e.g. signaling or user plane data).

27. Continuous Packet Connectivity
• small packets either continuously (e.g. Voice
over IP) or intermittently (e.g. presence
information of the messaging applications,
push email) require efficient support for
continuously connected applications.
• battery life and the capacity of the cellular
system will benefit from the introduction of
discontinuous transmission and reception in
active state.

28. Enhanced CELL_FACH operation
• HS-SCCH is continuously monitored in
CELL_FACH,URA_PCH and CELL_PCH
state with data transfer via the associated
HS-DSCH
• Increased data rate, reduced signaling
delay, and accelerated state changes

32. CONCLUSION
We have presented a detailed overview of the
HSPA Evolution, which consists of a number of
enhancements. The enhancements include
Multiple Input Multiple Output(MIMO), Higher
order modulation, Control channel
improvements, and Protocol enhancements.
With these improvements it should be possible
to reach performance close to the performance
goals of the Long Term Evolution. However, due
to smaller bandwidth and longer transmission
time interval, some LTE targets will not be
reachable.

33. GENERAL INFORMATION
• DEPLOYMENT
• On 10 June 2008 Australia's Telstra Next G network was the first to
enable some features of HSPA+.
• On 5 December 2008, the first 21 Mbit/s (downlink) and 5.8 Mbit/s
(uplink) data link was established on a commercial network (Telstra).
• On 23 October 2008, the first wireless data devices for the HSPA+
standard were announced. The devices, developed by Sierra Wireless
in collaboration with Netcomm,Telstra, Qualcomm, and Ericsson, offer
peak download speeds of 21 Mbit/s over Telstra's Next G network –
three times faster than currently available HSPA modems.
• In December 2010, BSNL started upgrading their entire 3G network in
760 Indian cities from the current HSDPA (7.2 Mbit/s) standards to the
HSPA+ standards with minimum speeds of 14.4 Mbit/s and maximum
speeds of 21.1 Mbit/s. The entire up-gradation process will be
completed by 31st March, 2011.
