Traditionally, every mobile station (MS) riding in the mobile vehicle uses conventional connection to the base station (BS). However, in 802.16j mobile multihop relay (MMR) networks, one of the studied usage model is ldquocoverage on mobile vehiclerdquo. Therein, a relay station (RS) is mounted on a vehicle. The RS provides service to MSs riding on the vehicle by relaying their data to the mobile...
This paper considers the ranging process of IEEE 802.16 system in relay system. An interference problem between MS-BS ranging (i.e. ranging between mobile station and base station) and MS-RS ranging (i.e. ranging between mobile station and relay station), which is caused by the introduction of relay systems, is addressed. A solution of the interference problem is provided by proposing a new transmit...
