Open Issues in Traffic Models Traffic models

VoIP model Related contributions: 04/12, 04/37, 05/05 Complete, specific model not available

Internet gaming model Contribution 04/86, 05/06 Additional contributions expected in January Interim meeting Need to determine the best option

Video streaming model Contribution 04/88, 05/11 Other new contributions expected in January Interim meeting Need to select an appropriate source data rate for evaluation

Traffic model mix Contribution 04/85r1 Need to determine the percentage mix for simulating the desired traffic models as listed

in the phase approach table

C802.20-05-04r3 6

Open Issues in Evaluation Criteria Document V.12

System Calibration

Part of Phase 1 evaluation Contribution 04/83r2, [07/07r1] Additional suggestion on calibration based on fixed user locations New contributions expected in January Interim meeting

Channel model mix

Contribution 04/82r1 Some questioned the need on the use of channel model mix Need to be consistent with channel models document

More open issues to follow …

C802.20-05-04r3 7

Link Budget Criteria

Link budget

Clarification text required to specify type of data requested, e.g., Channel environment Minimum Data Rate at the cell edge Alternatively, maximum cell size for the required minimum data rate

Technology Selection Process document will specify use of data

Need to provide a linkage between required performance metrics as

specified in section 13 and the link budget template

C802.20-05-04r3 8

Fairness Criteria

Fairness criteria for applications other than the best effort traffic need to be specified

Phase approach table listed various applications to be evaluated: Real-time Interactive traffic (VoIP, gaming) Streaming traffic (Video streaming) Non-real-time data traffic (HTTP)

Performance criteria not yet specified QoS performance – Delay, Error Rate [VoIP: 05/05] Outage criteria

What would be the performance criteria for each traffic type to ensure that the spectral efficiency is computed based on system resources being shared fairly amongst the simulated users in the same sector?

Contributions are required if additional metrics are to be adopted

C802.20-05-04r3 9

Phase 1 Simulation Methodology

19-cells, 3 sectors wrap around configuration

Traffic model Full-buffer (Hungry user) model

Channel model Suburban Macro Pedestrian B, 3 km/h Vehicular B, 120 km/h
