  • Patent number: 11191037
    Abstract: 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.

  • Patent number: 11159298
    Abstract: Systems and methods of providing DMRS for a UE are generally described. The DMRS locations in a resource unit of a Physical Resource Allocation of a shared channel are randomly determined, and the DMRS sequences randomly generated before transmission from a master UE to a wearable UE. The DMRS locations are disposed on different subcarriers and symbols in the resource unit and are repeated every k subframes or m resource units within the same subframe. In situations in which the collision/contention probability is relatively small, DMRS in control channels may be used rather than in the shared data channel.
