Summary of LTE-AdvancedRAN standardization

Study Item was closed in March 2010 Feasibilit of LTE-Advanced was confirmed in terms of erformance

backward compatibility, complexity, etc Technologies to be added to LTE Release 8 and 9 with full backward

compatability -

requirements of ITU-R IMT-Advanced Evaluation results were captured in TR 36.9 12

Specification work on RAN Release 10 Work Items was Carrier aggregation for LTE Enhanced Downlink Multiple Antenna Transmission for LTE UL multiple antenna transmission for LTE

etcRAN Release 10 specifications will be approved in December2010 to submit the specifications to ITU-R WP 5D in March 2011



13/22

Technologies to be included inLTE-Advanced(1/2)

LTE Release 8 can meet most requirements of IMT-Advanced. Two additional improvements to LTE performance needed:

Wider bandwidth To improve peak data rate and spectrum flexibility

Spectrum/carrier aggregation based on component carrier(CC) concept to keep backwardcompatibility and allow smooth network migrationSupport of maximum 5 component carriersEach com onent carrier has a bandwidth defined in Release 8/9Intra-band contiguous(, intra-band non-contiguous) and inter-band non-contiguousaggregationRRC management of primary and secondary component carriers per UE

Dynamic cross-carrier scheduling by MAC ,

Advanced MIMO techniques To improve peak data rate and cell/cell-edge spectrum efficiency Up to 8-layers for DL and 4-layers for UL

Dynamic SU/MU-MIMO switching

Support 4 spatial layers for MU-MIMO with maximum 2 layers per userImproved CSI feedback using double codebook structureDedicated reference signal structure to support advanced precodingNew codebook for 2Tx and 4Tx uplink MIMO


,and

Spectrum

Additional spectrum can beadded to the s ecifications

as required (eg. 3500MHzcurrently being added)

Re-farming 900/1800MHz GSM bands are

attracting a lot of attention, asspectrum re-farming in those

an s s seen as one way oallow the roll out of mobilebroadband services.

Offloading and Traffic Breakout Various traffic offload mechanisms defined in

Release 10

Local IP Access (LIPA) is used from a femtocellto access local network resources (such as a

IP Flow Mobility and Seamless Offload (IFOM) isused to carry some of a UEs traffic over wifi tooffload femto access.

Selected IP Traffic Offload (SIPTO) is used to

traffic out of the network early. SIPTO for femtocells may be deferred to a later release

Convergence (Technology)

3GPP LTE is a point of convergence, to unite theworlds operators on a common technology platform

2009 - CDMA Development Group (CDG) join 3GPP asa Market Representation Partner (MRP)

2009 - TD-SCDMA Forum pave the way for TD-LTE inChina

- u c a e y genc es announce ameets their requirements (See APCO, NENA, NPSTCAnnouncements )

Conclusions

3GPP LTE is set to be the major enabler for mobile broadband

Industrial input to the standards process is of an unprecedentedlevel

The first commercial LTE Networks have been launched based

on 3GPP Release 8 and R9 LTE-Advanced will enable new services & innovation beyond

3GPP Release 10,

TD-LTE and CDMA families as well as the fixed/mobilecommunities
