  • Publication number: 20220191560
    Abstract: The present invention relates to a data transmission device and reception device in a wireless AV system. Disclosed in the present specification is a wireless data transmission device comprising: a processor for generating a compressed bitstream by encoding media data; and a communication unit for segmenting the compressed bitstream, mapping the segmentation results to MSDUs, generating an MPDU frame sequentially including a MAC header, a frame body, and an FCS associated with the MAC header in order to transmit the MSDUs, generating a PPDU frame sequentially, which includes a preamble to which at least a portion of the MAC header is mapped, at least one PPDU to which the frame body and the FCS are mapped, and a TRN field, and transmitting the PPDU frame through a wireless channel. A data transmission rate can be improved through a reduction in overhead information.

  • Publication number: 20220068728
    Abstract: Disclosed are a method of monitoring a semiconductor device fabrication process and a method of fabricating a semiconductor device using the same. The monitoring method may include determining a normalization range of a target byproduct, which is a measurement target of byproducts produced in a chamber by an etching process, the byproducts including the target byproduct and a non-target byproduct, the target byproduct including first and second target byproducts, which are respectively produced by and before the etching process on a to-be-processed layer, obtaining a first index from a ratio of the target byproduct to the non-target byproduct, obtaining a second index by subtracting an emission intensity of the second target byproduct from the first index, obtaining a third index by integrating the second index on a time interval, and estimating a result of the etching process and presence or absence of a failure, based on the third index.

  • Publication number: 20220021422
    Abstract: The present disclosure relates to a data transmission apparatus and method using a polarized antenna in a wireless AV system, and a data reception apparatus and method. The present specification provides a method for performing polarization alignment for a downlink on the basis of reciprocity, a method for performing polarization alignment for an uplink, and a method for performing polarization alignment independently for each DMG antenna when one data transmission apparatus or one data reception apparatus uses multiple DMG antennas. Optimal MIMO performance can be guaranteed by aligning polarization between multiple antennas of the data transmission apparatus and the data reception apparatus in the wireless AV system, the polarization alignment for a downlink or an uplink may be selectively performed on the basis of reciprocity, and polarization distortion can be reduced through the independent polarization alignment between each DMG antenna.

  • Patent number: 9155063
    Abstract: A method of determining a position in a wireless communication system and apparatus thereof are disclosed. The present invention includes receiving system information including information on a reference cell and at least one neighbor cell from a location server, receiving positioning reference signals (PRSs) from the reference cell and the at least one neighbor cell using the system information, measuring reference signal time difference (RSTD) of each of the at least one neighbor cell for the reference cell, and transmitting the at least one measured RSTD to the location server. And, the RSTD is a relative timing difference between two cells. Moreover, the system information includes at least one cell for obtaining a system frame number (SFN) by the UE, as the reference cell or the at least one neighbor cell.
