3. Comment #26 Decision: Reject Reasons:
The mapping of QOS parameters does not relate to behavior prediction.
Measurement examples provided by Annex K have nothing to do with interoperability. There different methods for using MAC layer measurements and making inferences on the current quality of service conditions as seen by the device.
Annex K examples cannot be made mandatory since measurements provided by specs like 11k are not mandatory

4. Comment #189 Decision: Accept Reasons:
Adopt suggested changes for consistency
xxx

5. Comment #278 Decision: Accept Questions to commenter (JC Zuniga):
Are parameters mapped to CoS really computed per class of service?
Is there a link packet error rate computed on the aggregate classes?
xxx

6. Comment #279
Decision: Accept Reasons: Editorial
xxx

7. Comment #473 Decision: Reject Reasons:
Measurements available in the respective technologies are not even mandatory therefore can not make the mapping mandatory.
Measurement examples provided by Annex K have nothing to do with interoperability. There different methods for using MAC layer measurements and making inferences on the current quality of service conditions as seen by the device.

8. Comment #588, #590 Decision: Reject Reasons:
QOS is an important aspect of MIH and that’s why MIH provides useful tools in the form of primitives and events in order to make use of measurements available at layers 1 & 2.
The value of the MIH is not in defining new measurements in other technologies but in facilitating the exchange of information available.
While the tools provided by MIH are all normative, the measurements available in other specifications are informative.

9. Comment #620
Decision: Reject Reasons: same as comments 26, 286, 588 and 590
xxx

10. Comment #630
Decision: Comment Rejected Reasons: Throughput is defined as the instantaneous bit rate i.e. number of bits transmitted over a certain time interface. It is not intended to characterize the link’s speed. Text in the draft will be clarified to reflect that.
xxx

11. Comment #631
Decision: Accept Reasons: Text can be added to clarify that statistics are only valid on a given channel and at a given operating data rate.
xxx

12. Comment #632
Decision: Reject Reasons: Throughput is intended to reflect the instantaneous bit rate and therefore is closely related to link utilization.
xxx

13. Comment #633
Decision: Accept Reasons: Editorial. Add CoS abbreviation to list.
xxx

14. Comment #634
Decision: Accept Reasons: Add “available Admission Capacity for Supported number of CoS in table K0-1
xxx

15. Comment #635
Decision: Reject Reasons: this formula is provided as a way for the sender to infer that a packet is lost at the receiver by considering the ACK failure. Not clear what is meant by the comments “Many links exhibit finite PER with zero PLR” Note that PER is a theoretical value.

16. Comment #637
Decision: Accept Reasons: need to add summation to delay formula line 38
