this paper sheds the light on coexistence and sharing between high altitude platform system (HAPS) and WiMAX system. Spectrum etiquettes used for combined HAP and terrestrial fixed broadband systems. Spectrum etiquettes used to enable the coexistence of HAP and terrestrial systems. Nowadays, A HAPS becomes a recognized system in this band 5.75GHz.Therefore; terrestrial links are one of the most considerable interference with the HAP gateway station (HAPGS) links. Hence, coexistence of HAPS and WiMAX requires separation distance which must be achieved in terms of both co-channel and adjacent channel frequencies. Coexistence of the terrestrial subscriber station HAP and A HAPGS is impossible without interference mitigation and spectrum etiquettes. Therefore, these systems can work effectively and efficiently. Therefore the QoS sustain high. Based on the study results, the minimum separation distance should be 15 to 18 km away from the reference point. The isolation technique is applied in the distances less than 15 km and above 18 km in order to mitigate the interference. Consequently, the maximum isolation values should be 30.92 dB and 13.4 dB inserted between the WiMAX Station and HAPGS.
