The conventional orthogonal space-time block code (OSTBC) with limited feedback has fixed feedback bits for the specific transmit antennas. A new partial feedback based OSTBC which provides flexible feedback bits is proposed in this paper. The proposed scheme inherits the properties of having a simple decoder and the full diversity of OSTBC, moreover, preserves full data rate. Simulation results show that for transmit antennas, the proposed scheme has the similar performance with the
