Hi Dan,

I am OK with the current structure. Just need to change the reserved to 8
bits

Any other opinions on this issue? 

 

Roni, I understand that your preference for option 2 is not blocking. Am I
correct? 

 

Thanks and Regards,

 

Dan

Hi Qin and Roni,

 

I agree option 1 is more appropriate for this report block. And I'll revise
the "reserved"  field in section 3.2 to 8 bits.

Thanks.

 

Best Regards!

Rachel

I understand your reason. However in other XRBLOCK drafts using I field, at
least one type of Interval metric flag is used. 

unlike other XRBLOCK drafts using I field, none of Interval metric flags
(from I=00 to I=11) is used in this draft.

So I prefer to keep as it does.

Hi Qin,

My only reason for option 2 is to keep the header the same. There is no
other reason

Hi,Roni:

Thank for your comment, if I understand correctly, Initial Synchronization
Delay metric

Only needs to be reported once, i.e., at the beginning of the session since

the value of Initial Synchronization Delay metric usually is fixed and will

Not change at each report interval.

So I think your 1st option is more straightforward.

 

Regards!

-Qin

Hi,

I reviewed the latest version. It looks OK.

I have one comment

The "reserved" field in section 3.2 should be 8 bits since the "I" field was
removed.

Another option is to keep the "I" field and say that it should be ignored
