Patents by Inventor Kwon Jong LEE

Kwon Jong LEE has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11190954
    Abstract: A base station controller optimally controls activation/deactivation of small base stations in a heterogeneous network environment in which a number of base stations forming cells of different sizes coexist in the same area, taking into account traffic volume as well as signal interference. A method for operating the base station controller is also disclosed.
    Type: Grant
    Filed: May 19, 2015
    Date of Patent: November 30, 2021
    Assignees: SK TELECOM CO., LTD., INDUSTRY-ACADEMIC COOPERATION FOUNDATION, YONSEI UNIVERSITY

  • Patent number: 10491259
    Abstract: Disclosed is a terminal device that is capable of taking an advantage of increasing transmission capacity in the FD transmission as much as possible by selectively using the FD transmission or the HD transmission in a multi-cell communication environment in consideration of a relationship with other neighboring nodes (base stations and terminals). Also disclosed is a method of operating the terminal device.

  • Patent number: 10405321
    Abstract: A cell control device achieves optimal interference control taking into account a different between the DL interference strength and the UL interference strength by an adjacent cell by way of controlling cells based on D-TDD in a network environment where a number of cells employing TDD coexist. A method of operating a cell control device is also disclosed.
