NSN wil l implement EDGE Evolution in two steps

Step 1. Downlink Dual Carrier (DLDC) in RG10

Step 2. EGPRS-2 B(REDHOT, HUGE) in downlink and uplink inRG20

Two carriers from the same BTS

TBFs expanded over 2 carriers

Incremental redundancy betweencarriers is possible

MS may alternate between carriersin uplink

Doubled DL data rates over the whole cell area.Provided bit rates are sufficient for high quality video.

Average bit rates up to 400 kbps (2X5 slots)

Doubling of data rates in DL will be achieved

with the introduction of the 1.2 times higher

symbol rate with QPSK, 16QAM and 32QAMand turbo coding.

RED-HOT-B gains can be linked with MS

diversity or dual carrier.

Can provide over 50% improvement inspectral efficiency.

RED-HOT-B will introduce only 8 new

modulation and coding schemes.

RED-HOT-B outperforms EGPRS, thuslegacy symbol rate is needed only for

EGPRS signaling with CS-1 or sending USFs

to legacy EDGE MSs.

Trade-off between coverage and adjacentchannel power. EXxB DTRX HW required

Doubling of data rates in UL will be

achieved with the introduction of the 1.2

times higher symbol rate with QPSK,16QAM and 32QAM

Simulated spectral efficiency gains of

HUGE-B exceed 50%.

HUGE will use 8 new modulation andcoding schemes.

HUGE-B outperforms EGPRS, thus legacy

symbol rate is needed only for EGPRS

signaling with CS-1 Camera phones linked with new video

sharing services will likely increase bit rate

demand in uplink.

Substantial gain to end-user experience,thus revenue increase is expected.
