MMR: Mobile Multihop Relay
Mobile Multihop Relay (MMR) refers to the concept of relaying user data and possibly control information between an MMR base station and an IEEE Standard 802.16 compliant mobile station through one or more relay stations. Licensed spectrum is used for relay. The purpose of enabling relay is to enhance coverage, range, and throughput and possibly capacity of an MMR–BS and to enable very low power devices to participate in the network. The adjective “mobile” used here refers to the fact that both mobile subscriber stations and mobile relay stations are supported. It is possible to establish multiple communications paths between the MMR-BS and an MS and to communicate the same user data and/or control/management information through both paths to improve communications reliability.
