Systems, methods, and instrumentalities are disclosed for power control for aerial wireless transmit receive units (WTRUs). Power control may be open loop and may be managed based on altitude. Open loop power control may be based partly on path loss estimation from neighboring cells and may be coordinated among interfering neighboring eNBs using path loss information. Dynamic power control may be driven by the WTRU. Reference signal transmissions by an eNB may use uplink resources for path loss estimation, and interference estimation may be based on uplink reference signals. Path loss estimation may be based on downlink reference signals. Dynamic blanking may be provided for Cell-specific Reference Signals (CRS), and random access (e.g. RACH) may be provided for aerial WTRUs.
