Abstract：In recent years, increasing demand for high speed, but the limited frequency spectrum resource seriously hindered the implementation of a higher rate of business. 60 GHZ frequency band millimeter wave due to its free permits, received a lot of attention. This thesis mainly, according to the theory of millimeter wave WPAN spatial reuse key technology. In the existing spatial reuse scheduling algorithm, or use the full channel state information(CSI) feedback or use none feedback.All have problems: full-CSI is more accurate, but with much too feedback. None feedback have no idea of the CSI, so the scheduling link is randomly, finally influence the system. Thus, this thesis puts forward a new solution: reduced feedback theory was applied to 60 GHZ system. Detail solution is: the PCP get CCI by beam forming in all the stations, then feedback the CCI to PCP. The feedback is reduced to 1 bit. PCP then scheduling the slots using the reduced feedback best link coexisting algorithm. Verified the feasibility of the algorithm above by simulating and compared with the Blind and full-CSI feedback maximum coexistence links algorithm in spatial reusing gain and time complexity. Across the thesis, full-CSI feedback means feedback all the channel state information, reduced feedback means feedback part of the channel state information.
