2. Definitions [1] HR-MS –A subscriber station that complies with the requirements for subscriber stations in this amendment HR-BS –A base station that complies with the requirements for base stations in this amendment HR-RS –A relay that complies with the requirements for relays in this amendment HR-network –A network whose stations comply with their respective HR requirements in this amendment HR-station –An HR-MS, HR-BS or HR-RS. Infrastructure station –An HR-BS or HR-RS

3. Proposed SARM HR-Network Infrastructure Station HR-MSHR-BSHR-RS HR-MSHR-BSHR-RS MSBSRS Non-HR-Network Backhaul Network MSBSRS : Possible wireless links between entities : 0, 1, or multiple links in between : Special operation including RS-mode or BS-mode

4. Notes on the Proposed SARM The connections with non-HR devices –HR & non-HR MS HR & non-HR RS/BS Multi-path availability [2] –HR-MS may connects to multiple HR-RS HR-MS & HR-BS inter-connections –HR-MSs may form a network by themselves. –HR-BS may connect to each other.

5. Proposed Resolution Adopt the figure for the proposed SARM
