I am a bit confused by the draft reply. The request was for feedback on: 1) whether there are any accuracy requirements for “Estimated Throughput”, 2) “Estimated Throughput”'s variations across different implementations 3) feasibility of “Estimated Throughput” calculation by either STA or AP 4) if it would be feasible for IEEE to define “Estimated Throughput” accuracy requirements, if not already defined 5) other metrics which can also be useful for LWA operation The draft reply addresses 1 and 2. It does not address 3 or 4 and mentions but does not really address 5. Conversely, it goes into discussion of "pre-activation and post-activation phases of LWA" which does not in any obvious way relate to the 5 requests made. Incidentally, as regards 3 and 4, the ESTT mechanism was examined during TGm sponsor ballot comment resolution, and the conclusion was that it is not feasible to calculate in one direction (I forget which) because required information is missing, and the calculations in R.7 are inaccurate anyway.
