Linear programming of \( {P}_{i,j}^D \) and \( {P}_{i,j}^{VR} \) power control. The figure shows the possible shape of the feasible region under different wireless channel conditions. \( {P}_j^{D,\operatorname{MAX}} \) and \( {P}_i^{VR,\operatorname{MAX}} \) denote the maximum transmission power of Dj and VRi respectively. lvr and ld represent SINR constraints of transmission power for Dj and VRi
