30 IEEE j: Mobile Multihop Relay PAR Approved on March 30, 2006 Expected Date of Submission for Initial Sponsor Ballot: March 07 Projected Completion Date for Submittal to RevCom: Sep. 07 Scope of Proposed Project: OFDMA physical layer and medium access control layer enhancements to IEEE Std for licensed bands to enable the operation of relay stations. Subscriber station specifications are not changed. Purpose of Proposed Project: To enhance coverage, throughput and system capacity of networks by specifying multihop relay capabilities and functionalities of interoperable relay stations and base stations. Reason for the Proposed Project: The multihop relay is a promising solution to expand coverage and to enhance throughput and system capacity for IEEE systems. It is expected that the complexity of relay stations will be considerably less than the complexity of legacy IEEE base stations. The gains in coverage and throughput can be leveraged to reduce total deployment cost for a given system performance requirement and thereby improve the economic viability of IEEE systems. Relay functionality enables rapid deployment and reduces the cost of system operation. KRnet
