\item The receiver obtains the channel vector ${\pmb h}$, picks the appropriate rate and transmit beamforming vector from $\mathcal{C}_R$ and $\mathcal{C}_b$ and sends their indices to the transmitter.  \end{enumerate}  Let $\mathcal{C}_{R} = \left\{R_0 = 0, R_1, R_2, \ldots, R_{2^{B_1}}\right\}$. R_{2^{B_1}-1}\right\}$.  The selected rate for the transmitter will be $R_{\star}$ $R_{s}$  such that $R_{\star} $R_{s}  \leq \left|\left|\pmb h\right|\right|^2 \leq R_{\star}$ R_{s+1}$, where $0 \leq s\leq 2^{B_1}-1$.  \section{Power Allocation for Non-Orthogonal Multiple-Access (NOMA) Systems with Limited Feedback}
