“…[4] studied an optimal power allocation mechanism in the novel architecture, and [21] presented the cognitive exploitation schemes for both the forward-and return-links devoting the improvement of system performance. Considering the real-time applications in the CSTNs, the authors in [23] maximized the delay-limited capacity and outage capacity of the satellite link by designing two power control schemes. In [24], the outage probability expression of the terrestrial secondary user (SU) was derived in a closed-form while satisfying the interference constraint to the satellite primary user (PU) imposed by wireless terrestrial network.…”

“…When the fixed-service terrestrial microwave system operated as the primary system, the power allocation scheme was proposed for the fixed satellite service system in [8]. Considering the delay-sensitive service, two optimal power control schemes were presented in [9], which optimized the delay-limited capacity and outage capacity, respectively. Nevertheless, all these previous works were based on the assumption of perfect channel state information (CSI).…”

“…Multiuser interference detection and cancelation on the user side [15,16]: Advanced precoding schemes at the transmitter side Exclusive regulation of spectrum assignment [17] Cognitive radio-based spectrum sharing between HTS and terrestrial systems with interference management [18,19] [ 20,21]: Various interference scenarios and cognitive modes in cognitive satellite terrestrial networks [22]: Cognitive zone to guarantee the primary communications [23]: A joint carrier-powerbandwidth allocation scheme [24][25][26]: Power allocation with interference-power constraints One reason for the limited throughput is the inefficient utilization of the deployed spectrum in HTS systems. To increase the bandwidth utilization efficiency, the authors in [8] proposed to dynamically allocate the orthogonal bandwidth based on different traffic demands.…”

“…In [25], the authors conducted power allocation to maximize the achievable rate for cognitive hybrid satellite-terrestrial networks with amplify-and-forward (AF) relays. In addition, for real-time satellite applications in cognitive satellite-terrestrial networks, the authors in [26] conducted power control to maximize the delay-limited capacity without degrading the communication quality of the primary terrestrial user.…”
