Re: [STDS-802-16] MMR usage models

Hi evrybody,
If we consider well the problem of mesh usage model, It seems to me that in reality this case is already treated in 802.16-2004/802.16e. How? :
If in the same time BS/SS and  SS/SS direct communications can occurs. then  we could say that multi-hop communication could occur between any node in the network. This is of course thanks to Level 3 routing protocols.
The problem of coverage extension doesn't exist anymore because any fixed SS could considered as equivalent to Relay Stations . This also will increase the global network throughput. Such RS-like SSs will have the architecture as any other SS. The only difference is that this SS will be dedicated to relaying traffic.
Do you agree with me?

Hi all,

Sure, it is Out of scope.

I believe that is out of the scope of 802.16j. The MMR should be

backward compatable in the sense that the MS specification

should not be changed. Can we allow MS-to-MS communication

without changing the current specification?

Hi,
When reading "Harmonized Contribution on 802.16j (Mobile Multihop Relay) Usage Models ? Revision R4". We can see that a the general architecture is based o na PMP architecture assuming a possible relaying through FRS,NRS or MRS. Could we consider a usage model where direct communications can occur between MSSs. In other words, could we consider a "mesh usage model". In which case, we can find all types of links especially MSS-MSS links. This will be useful when applicative traffic should occur between MSSs or between MMS and  FRS/NRS/MRS. There is no need that the traffic transit via the BS.
What do you think about this?
