  • Patent number: 10382993
    Abstract: The present disclosure relates to a 5G or pre-5G communication system that will be provided to support a higher data transmission rate beyond a 4G communication system such as LTE. Disclosed is an interference measurement method and device in a flexible duplex system. The method comprises the steps of: determining whether uplink (UL) grant for allocating UL transmission has been received from a base station in a first subframe; when the UL grant has not been received, measuring inter-cell interference for an uplink interference measurement resource (IMR) in at least one second subframe determined by the first subframe; and when the UL grant has been received, measuring inter-cell interference for the uplink interference measurement resource (IMR) in at least one third subframe before a subframe that is indicated by the UL grant.

  • Publication number: 20190088909
    Abstract: A method for manufacturing a display device is provided. A process of forming an inspection pattern, in which a protective film unit is partially removed in a thickness direction, in a pad area portion of the protective film unit, which corresponds to a pad area of a display unit, may be performed, and then, a process of delaminating the pad area portion of the protective film unit may be performed. A process of checking whether the inspection pattern exists may be performed to check whether the delamination has succeeded, and, at the same time, a process of measuring distances from an alignment mark to each of a long side and a short side of the display unit may be performed.
