Dear all Regarding the base documents, I have suggestions and
things to clarify. I think AAS HO should be
considered in 802.16e. Thus, I have added one more scenario and assumption on
the list (marked in red). I have suggested 5
possible handover scenarios with IP change consideration. I want to hear your
opinion on this. (I have uploaded
"C802.16e-04_105_0601" on the FTP server
http://upload.wirelessman.org in handoff ad hoc directory) I have several things to
clarify. 1. Does minimal
assumption 1 and 2 "HO occurs between single sector BTS and Each sector is
at a different frequency" mean that one BS only can have one sector? If so, this
doesn't comply with the Assumption of Intra BTS HO with multiple sectors on the
table. This assumption seems to me that either one BTS has more than one sector
or more than one FA. 2. Does minimal
assumption 3 "FA is unknown" mean that we will only consider 1 FA
case or we have to consider all possible cases? 3. Please someone clarify
what are the differences between Basic and Advanced? 4. Which case does
Scenario name "Basic-Same-freq" and assumption "HO between
sectors at the same frequency" represent? It seems to
me this doesn't comply with the minimal assumption 2 "Each sector is at a
different frequency". 5. Can
basic/Advanced-MIMO be discussed without a consideration of different technologies?
6. If two base stations
use different frequencies, how soft handover is possible? 7. Is MBS issue out of
scope of handoff Ad hoc, even though MBS is related to the handoff? I think we need to unify
the terminology on the base document, e.g. use BS instead of BTS. Regards, Ronny(Yong-Ho) Kim LG Electronics |
