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

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
