Abstract

oAn analytical model is proposed to evaluate the Listen Before Talk (LBT) based coexistence scheme over the unlicensed spectrum under multiple LTE small bases (SBSs). Based on the proposed model, the expressions of the occupancy time of the LTE/WiFi/access overhead and the collision probability is further derived. The Numerical results show that under multiple LTE SBSs the LBT based coexistence scheme is not fair enough for the WiFi system. Therefore, in order to protect the WiFi system the number of LTE SBSs and the length of the LTE frame should be carefully designed.
