… secure resource allocation problem for a downlink multiuser symbiotic radio network with
imperfect channel station information (CSI) and eavesdroppers. Based on bounded CSI error …

… To evaluate the impact from imperfect CSI on the resource allocation in the dual-spectrum
system concerned, we establish a saturated traffic model with the stochastic channel power …

… 3, we also show the effect of imperfect CSI on the performance of the proposed resource
allocation approach and baseline methods. The results show that the achievable goodput of …

… in [19] with imperfect CSI at the base station, and a two-stage power allocation scheme was
… : 1) We extend the study of CNOMA systems with imperfect CSI proposed in [21] to multiple …

… CSI of the interfering links. This motivates us to study distributed beamforming and power
allocation schemes that are robust against CSI … on the availability of the CSI of the interfering …

… imperfect CSI by using mathematical approximation methods. And we transform the power
allocation … method to get the optimal power allocation coefficients, considering the sensitivity …

… users (Ui and U2) are derived in the case of imperfect channel state information. Then, we
find optimal power allocation factors for different distances of Ui to satisfy the OP fairness for …

… loss resulting from imperfect CSI was investigated and the … allocation scheme was proposed
to maximize the rate. Furthermore, the achievable rate of IA in the presence of imperfect CSI …

In this paper, we address the problem of joint scheduling and resource allocation in the
downlink of an orthogonal frequency division multiple access (OFDMA)-based wireless network …

… decisions are made by a low-complexity iterative power allocation algorithm designed for …
perfect CSI is available at each BS, in this paper (see Section III. C), we obtain the local CSI at …
