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

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
