  In this paper, we have studied the bit partitioning schemes for the multicell
multiple-input and single-output (MISO) infrastructure. Zero forcing
beamforming is used to null out the interference signals and the random vector
quantization, quantizes the channel vectors. For minimal feedback period (MFP),
the upper bound of rate loss is calculated and optimal bit partitioning among
the channels is shown. For adaptive feedback period scheme (AFP), joint
optimization schemes of feedback period and bit partitioning are proposed.
Finally, we compare the sum rate efficiency of each scheme and conclude that
minimal feedback period outperforms other schemes.
