  • Publication number: 20220255709
    Abstract: Provided is a radio communication device which can prevent interference between SRS and PUCCH when the PUCCH transmission bandwidth fluctuates and suppress degradation of CQI estimation accuracy by the band where no SRS is transmitted. The device includes: an SRS code generation unit (201) which generates an SRS (Sounding Reference Signal) for measuring uplink line data channel quality; an SRS arrangement unit (202) which frequency-multiplexes the SRS on the SR transmission band and arranges it; and an SRS arrangement control unit (208) which controls SRS frequency multiplex so as to be uniform in frequency without modifying the bandwidth of one SRS multiplex unit in accordance with the fluctuation of the reference signal transmission bandwidth according to the SRS arrangement information transmitted from the base station and furthermore controls the transmission interval of the frequency-multiplexed SRS.

  • Publication number: 20220253004
    Abstract: An image forming apparatus includes an image carrier, an exposure device to expose the image carrier to form an electrostatic latent image on the image carrier, a conductive member, and a developing device having a rotatable developing roller and a rotatable toner supply roller. Polarity of direct-current components of biases applied during image forming operation to the conductive member, the developing roller, and the toner supply roller are the same as a polarity of normally charged toner. An absolute value of the bias applied to the developing roller during the image forming operation is smaller than an absolute value of the bias applied to the toner supply roller during the image forming operation. The absolute value of the bias applied to the toner supply roller during the image forming operation is smaller than an absolute value of the bias applied to the conductive member during the image forming operation.
