| Abstract: | In the present paper, power aware dynamic spectrum assignment techniques are proposed, which aim to achieve high spectrum utilization by allocating the experimental licensed 95 GHz Tera-Hertz (THz) spectrum to primary mobile service providers (p-MSPs) of a nation (i.e. India). The proposed techniques (i) consider cognitive radio-based spectrum access/assignment (SA) methods, viz., interweave SA (IW-SA) and underlay SA (UL-SA) individually and in a combined manner (IW-UL-SA), (ii) evaluate the optimal spectrum amount needed by every p-MSP and (iii) use p-MSPs to control the transmission power of small cells of the buildings/homes of every MSP over the entire nation. Extensive simulation experiments are conducted to evaluate the performance of the proposed methods considering various metrics. The obtained results show that the proposed methods outperform the static spectrum assignment (SSAs) method, and among the proposed methods, IW-UL-SA outperforms IW-SA and UL-SA irrespective of the considered performance metric. Specifically, compared to when IW-SA and UL-SA are implemented, IW-UL-SA improves the mean capacity, spectral efficiency (SE), and mean system throughput by approximately "1.7" and "1.5", respectively, and energy-efficiency (EE), and cost-efficiency by approximately 64.5% and 64%, respectively. Further, the results also show that the proposed techniques meet the SE and EE needs of 6G wireless systems since compared to SSAs, IW-UL-SA, IW-SA and UL-SA use approximately 16.66%, 33.33% and 33.33% lesser number of buildings/homes of the small cells, respectively.
