We propose a distributed radio resource allocation method based on macrocell/picocell partial Channel State Information (CSI) sharing for small cell networks with range expansion. The Macro Base Station (MBS) predicts the cell- edge Pico users' Resource Block (RB) allocation based on these shared CSIs, and reduces its transmit power only in RBs with high allocation probabilities. Unlike most previous works, we analyze the post-scheduling outage probability encompassing the effects of channel- based scheduling and random user positions. Thanks to the analysis, we can easily find the MBS power constraint that minimizes this outage probability. The results show that the proposed scheme largely improves outage probability and macrocell user offloading, compared to conventional methods.
