Opps, there are some
typo. So I correct it as followings. Panyuh Joo From:
Panyuh [mailto:panyuh@samsung.com] Dear Ramzi and all, If we read the PAR of
MMR task group, it is easy to understand the relay is not related to the mesh
network in 802.16-2004 at all. Because in the context
of the 802.16-2004, the mesh topology is defined under unlicensed spectrum and
using only OFDM as PHY layer. But, the 16 MMR is
limited project for only an amendment of 16-2004 + 16e-2005 with licensed
spectrum and it is definitely not related to mesh topology at all. So as to the context of
802.16 the MMR is amendment of PMP (point to multipoint) topology with licensed
spectrum. So Please take a look at
the PAR of 16 MMR : P802.16j Thanks and regards. Panyuh Joo ============================ Global

Jose Costa [mailto:costa@NORTEL.COM] Hi Ramzi, A multihop relay network
is generally a partial mesh network. Here are some definitions
from the Preliminary draft new Recommendation ITU-R M.[8A/VOC.LAND.MOB] -
Vocabulary of terms for the land mobile service (Annex
18 to Doc. 8A/376): A mesh network is a network in which there are two
or more paths to any node. NOTE – There are two types of mesh
networks: full mesh and partial mesh. In a full mesh every node is connected to
every other node in the network. In a partial mesh some nodes may be organized
in a full mesh scheme but others can only connect to some nodes in the network.
A radio relay network is a network of relay stations. NOTE 1 – Relay networks can be one-hop
or multi-hop. One-hop relays are implemented with P-P and/or P-MP techniques.
Multi-hop relays are implemented using MP-MP techniques to form a mesh. NOTE 2 – The relay stations in a network can be fixed,
nomadic or mobile. A relay station is a station that performs message/signal transfer
without any reference to a user application. I hope this is useful. Regards, José From:
