  • Patent number: 11949613
    Abstract: An apparatus of a network (NW) configured to: encode a new radio (NR) Discovery Reference Signal (DRS) transmission, the NR DRS transmission including a synchronization signal block (SSB) and channel state information (CSI) reference signal (RS) (CSI-RS). The apparatus is further configured to configure the NW to transmit the NR DRS transmission. The RS-CSI may be a fragmented RS-CSI including a first fragmented portion and a second fragmented portion, where the apparatus is configured to encode a symbol of the NR DRS transmission to comprise the first fragmented portion, a symbol of the SSB, and the second fragmented portion, where the symbol of the SSB is encoded on a physical broadcast channel (PBCH) portion of the NR DRS transmission.

  • Patent number: 5241815
    Abstract: A heat-recovering-thrust-turbine including the rotational flow path has been invented in present work. This thrust turbine consists of a rotating disc having unique shape and functions of compressor and turbine together, a combustion chamber, manifolds for heat recovering and a divergent nozzle having the curved flow path in a different way of conventional gas turbine engines utilizing a straight discharging mechanism of the exhaust gases.Thus, this invented thrust turbine is able to perform the combined function such as compression of air, cooling of the hot section, recovery of the wasted heats and generation of the thrust and the turbine power being used for the air compression, simultaneously.
