stds-80220-requirements: suggestion to modify section 4.2.3 in 802.20requirements Rev 8b
Dear all,
The following is a suggestion to modify the last statement in section 4.2.3,
Performance Under Mobility & Delay spread:
Current text: "The system should support a delay spread of at least 5
micro-seconds."
Suggestion for the new text: "The system should support the above channel
environments with at least 90% link reliability."
Rationale: Based on the presentations on channel models during the Singapore
meeting, the delay spread of channels can be much larger than 5
microseconds. In addition, delay spread is one of the parameters in the
mobile channel models, there are also other parameters in the channel model
that are also important and can affect the performance significantly. The
capability of the system would be too limited if it is only going to work in
channels with delay spread of 5 microseconds.
Best regards,
Anna.
