This contribution provides support for SDD comments on network architecture and protocol structure. It proposes that the IEEE 802.16m group include an IEEE 802.16m MS to IEEE
802.16m MS link and supporting protocol block functions consistent with proposed IMT-
Advanced Requirements on network topologies.
To adopt the proposed IEEE 802.16m network and protocol architectures as working assumptions

This contribution proposes modifications to the overall system architecture to enable multi-hop and peer-to-peer communications utilizing IEEE 802.16m mobile station relays (MS) for improving coverage, capacity and throughput. The draft IEEE 802.16m SDD (IEEE 802.16m-08/003) recognizes both the IMT-Advanced
Requirements and the advanced services and applications described in ITU-R M.2072. The IMT-Advanced
Network Topology requirement has proposed multi-hop, mesh and P2P (peer-to-peer) modes as well as selfoptimization of network performance with respect to service availability, QoS, network efficiency and throughput. The ITU-R M.2072 World Mobile Telecommunication Market Forecast recognizes the trend for peer-to-peer relations and personal empowerment. As such, the 802.16m operational requirements call for multihop relay support and self-optimization.
Modify clause 4 (page 7, line 21) by inserting the following after line 21 and replacing Figure 2:
The IEEE 802.16m MSs may serve as opportunistic ad hoc relay stations to provide improved coverage, throughput and/or capacity and to provide improved throughput in a direct link between two proximate IEEE
802.16m MS which can be supervised by a IEEE 802.16m BS (see Figure 2). Because IEEE 802.16m MS may serve as opportunistic ad hoc relay stations, communications between the BS and the IEEE 802.16m MS can occur directly or via relay.

Modify clause 8.2 (page 15, line 13) by appending the following text to line 13:
IEEE C802.16m-08/154
Self Organization block performs functions to support self configuration and self optimization mechanisms. The
Functions include procedures to request MSs to report measurements for self configuration and self optimization and receive the measurements from the MSs. The functions also include procedures to enable the self configuration and control of IEEE 802.16m MSs for opportunistic ad hoc relay and peer-to-peer connections.
The Routing block manages the discovery and maintenance of direct link and multi-hop relay connections through IEEE 802.16m MSs.
