Abstract: The knowledge of the variability of a received signal at distant points to the Base Station (BS) is key for reliable and efficient radio signal transmissions. In consequence, developing a robust Path Loss Model (PLM) for determining the Path Loss (PL) between a High Altitude Platform Station (HAPS) and the User Equipment (UE) on the ground is crucial in positioning the HAPS. This paper presents a HAPS PLM for Ede environment. The PLM was developed based on some demographic data of the Ede land area. The parameters employed in the development of the PLM......

Abstract: The continuous growth in Device-to-Device (D2D) and Machine-to-Machine (M2M) communications demands for a robust uplink Radio Resource Management (RRM) strategy. However, radio waves in a mobile cellular radio access network such as the Long Term Evolution (LTE) network are faced with the problem of Intercell Interference (ICI) which limits the achievable system throughput. Thus, this paper proposes a Quality-of-Service (QoS)-based ICI mitigation (QICIM) scheme for the LTE network uplink. The proposed QICIM scheme involves coordination among the cells that make up the network to achieve maximum system throughput via QoS priority and effective power control for interference mitigation among the User Equipment (UEs).......
