Yuza, Dave and All:
I agree with Yuza that the usefulness of link budgets in the functional requirements is questionable. Instead, I suggest a useful place is in evaluation criteria and/or in channel model descriptions.
The functional requirements should reflect performance under different propagation conditions (multipath, mobility & doppler, interference, etc.). The link budget reflects implementation for specific RF designs.

Dear Dave and all:
I have a comment for "Functional Requirements Rev 3.".
Section 4.6 Link Budget
Page 11, Lines 31-Page 12, Lines 3
COMMENT:
Definition of link budget shall be involved in the transmission power a part of product performance not the system performance.
That makes a possibility of not to implement by EIRP standards in each country, and the value shall not be defined here.
Thank you.
Regards,
