Aerial base stations (ABS) provide promising solutions for wireless coverage in adverse scenarios. By jointly designing with cooperative transmission, the system performance can even be boosted. In this paper, we consider an ABS-assisted cooperative system, where multiple ABSs hover around the macro base station (MBS) and relay the downlink signals through non- coherent joint transmission (NC-JT) to the user equipment (UE). Interfering nodes are randomly distributed over the 2D plane. Non-uniform line-of- sight (LoS) channel model is assumed for the desired signal propagation, while the communication links between ground terminals follow a distance related probabilistic LoS and non-line-of-sight (NLoS) channel model. Based on stochastic geometry framework, we derived closed form success probability for the cooperative system. Numerical results verify the accuracy of our expressions and show that jointly transmitting signals from the sky can bring in significant enhancement for the coverage performance of the system.
