A User Equipment (UE) beamforming method is proposed for massive MIMO based stratospheric communications with multiple High Altitude Platforms (HAPs). The method leverages multiple-antenna UEs to mitigate interference from neighboring HAPs. No additional channel information exchange between UEs and HAPs is needed. The beamforming vector is obtained at the UE side by using the semi-definite relaxation based method. Both the Rician channel model and the HAP- MIMO channel model based on the dynamic evolution of scatters are adopted. Simulations under various environmental configurations demonstrate the performance improvement of the proposed method.
