  • Patent number: 11490455
    Abstract: Disclosed is a scheme of transmitting various types of radio signals for which interference between adjacent cells is considered in a radio communication system (for example, dynamic TDD) in which uplink communication and downlink communication can be dynamically switched. A feature of the present invention relates to user equipment including a transceiver that performs transmission and reception of a radio signal with a base station in accordance with a communication scheme in which uplink communication and downlink communication are dynamically switched and a signal processor that processes the radio signal, wherein the transceiver transmits a connection request signal generated by the signal processor in fixed uplink radio resources of the communication scheme.

  • Patent number: 11477773
    Abstract: A terminal and base station are disclosed where the terminal includes a receiver that receives a signal of a downlink shared channel and a processor that controls reception of a demodulation reference signal included in the downlink shared channel. The processor controls reception of a demodulation reference signal based on one of a first mapping method or a second mapping method. The first mapping method being a method in which the demodulation reference signal is mapped to a fixed symbol within a slot of the downlink shared channel, and the second mapping method being a method in which the demodulation reference signal is mapped to a top symbol of symbols for which the downlink shared channel is scheduled.

  • Patent number: 11447848
    Abstract: A steel sheet wherein a steel structure of an inside of the steel sheet contains, by volume fraction, soft ferrite: 0% to 30%, retained austenite: 3% to 40%, fresh martensite: 0% to 30%, a sum of pearlite and cementite: 0% to 10%, and a remainder including hard ferrite. In the steel sheet, in a ? to ? thickness range, a proportion of retained austenite having an aspect ratio of 2.0 or more is 50% or more, and a soft layer having a thickness of 1 to 100 ?m from a surface in a sheet thickness direction is present. When an emission intensity at a wavelength indicating Si is analyzed in the sheet thickness direction from the surface by a radio-frequency glow discharge analysis method, a peak of the emission intensity appears in a range of more than 0.2 ?m and 5.0 ?m or less from the surface.
