Let $\mathcal{C}_{R} = \left\{R_0 = 0, R_1, R_2, \ldots, R_{2^{B_1}-1}\right\}$ be the codebook for the fixed-length quantizer $\mathcal{Q}_{R}$. The selected rate for the transmitter will be $R_{s}$ such that $R_{s} \leq \left|\left|\pmb h\right|\right|^2 \leq R_{s+1}$, where $0 \leq s\leq 2^{B_1}-1$.
Let $\mathcal{Q}_{b}$ be the variable-length quantizer in our previous work. Then, for ${\pmb h}$ and the selected rate $R_s$, we can find an appropriate beamforming vector such that $\left|{\pmb
h}^{\dag}{\pmb h}^{+}{\pmb w}\right|^2 \geq R_s$
