  • Communication system and operating method thereof
    Patent number: 11902006
    Abstract: Provided are a method of operating a communication system, the method comprises mapping some antennas selected from among a plurality of antennas of each of a plurality of first communication nodes and reception ports of a second communication node, combining uplink signals mapped to an identical reception port of the second communication node from among uplink signals received through the plurality of antennas, and transmitting the combined signals to the mapped reception ports of the second communication node, respectively.
    Type: Grant
    Filed: November 25, 2020
    Date of Patent: February 13, 2024
    Assignee: SOLiD, INC.
    Inventors: Woosik Moon, Hoony Hong, Kwon Kim, Hyunchae Kim
  • Repeater and method of operation thereof
    Patent number: 11778485
    Abstract: A method of operating a repeater comprises detecting a synchronization signal from a received communication signal, identifying a time division duplex (TDD) switching pattern based on a power change of the communication signal over time and switching an uplink operation and a downlink operation of the repeater based on the detected synchronization signal and the TDD switching pattern.

  • COMMUNICATION NODE, COMMUNICATION SYSTEM AND OPERATING METHOD THEREOF
    Publication number: 20220394783
    Abstract: Provided are a method of operating a communication system using physical layer division, the method comprises extracting an initial random access signal from an uplink signal, in a first physical layer of a first communication node of the communication system reducing a data amount of the extracted initial random access signal in the first physical layer and calculating a time synchronization error using the initial random access signal with a reduced amount of data, in a second physical layer of a second communication node of the communication system.
