文摘

The relay station (RS) is widely used in major wireless technologies such as WiMAX and long term evolution (LTE) which provides cost effective services to the operators and end users in order to provide guaranteed Quality of Service (QoS). The existing research in IEEE802.16m to cover a base station (BS) territory in rural areas using four RSs in order to provide the services to mobile users beyond the range of BS has proven to be a costly solution. In this paper, how to use the available spectral resources as efficiently as possible to minimize the delay and improve throughput for end users with high demanding applications such as voice and video with decreased deployment cost of RS has been investigated. A novel solution has been proposed for cost effective deployment of three RSs in IEEE802.16m using adaptive modulation and coding (AMC) scheme, cell sectoring and directional antenna. The simulation results show that enhanced performance can be achieved by using less number of RS in the same BS territory without compromising the QoS and throughput of the WiMAX2 Network.
