3GPP Self-evaluation Methodology and Results

“Self-evaluation Results”


3GPP Self-evaluation for LTE-AdvancedSummary

The 3GPP self-evaluation has shown that the LTE Release 10 & beyond (LTE-Advanced) SRIT and the individual FDD RIT and TDD RIT components completely satisfy the criteria of Step 7 and should move forward to Step 8 of the process. In particular, the SRIT and the individual FDD RIT and TDD RIT components meet all the requirements in all four of the four defined test environments.The evaluation results were based on the rigorous calibration effort.

RIT: Radio Interface Technology SRIT: Sets of RIT

1.3 DL control channel overhead assumption

DL control Data

1 subframe = 1.0 msec = 14 OFDM symbols

L: OFDM symbols (L=1, 2, 3)

Downlink performances have been evaluated taking into account the downlink overhead for L = 1, 2 and 3 casesDynamic assignment of L is supported already in the Rel. 8 specification

Average overhead depends on the environments

6 Simulator calibration

How to reproduce 3GPP results?

Recommended simulator calibration procedures

Step 1: Implement ITU-R environments Check that pathloss and geometry distributions are in line

with 3GPP resultsStep2: Implement basic LTE models (1 x 2)

Check that spectral efficiency and user-throughput are in line with 3GPP results

Step3: Implement Rel-8 functionality (DL 4 x 2 SU-MIMO, UL 1 x 4 SIMO)

Check that Rel-8 performance is in line with 3GPP results This should enable reaching most ITU-R requirements

Step4: Implement advanced LTE functionalityCheck that remaining ITU requirements can be reached

6 Simulator calibration Step 3 and 4 results

Results shown in Slide 13 - 31


6 Simulator calibration: parameters (1)

MMSE in frequency domain, MRC over antennas

(no intercell interference rejection)

Uplink receiver type

Maximum four transmissionsProponent to specify IR or CC

Uplink HARQ

Based on delayed measurements. Ideal channel estimate from UL transmission in subframe n can be used for rate adaptation in

subframe n+7MCSs based on LTE transport formats [TR36.213]

Uplink Link adaptationP0 = -106dBm, alpha = 1.0Uplink Power control

Frequency Domain Multiplexing – non-channel dependent, share available bandwidth between users connected to the cell, all users get

resources in every uplink subframe. With M users and Nrb PRBs available, Mh=mod(Nrb,M) users get

floor(Nrb/M)+1 PRBs whereas Ml=M-Mh users get floor(Nrb/M) PRBs

7. Conclusion

The 3GPP self-evaluation has shown that the LTE Release 10 & beyond (LTE-Advanced) SRIT and the individual FDD RIT and TDD RIT components completely satisfy the criteria of Step 7 and should move forward to Step 8 of the process. In particular, the SRIT and the individual FDD RIT and TDD RIT components meet all the requirements in all four of the four defined test environments.The evaluation results were based on the rigorous calibration effort.
