    • PROBLEM TO BE SOLVED: To achieve a method that is capable of solving problems that a resource element is wasted and mapping becomes impossible during PCFICH (Physical Control Format indicator Channel) mapping.
      SOLUTION: A method, which transmits a physical control format indicator channel symbol to a terminal using a downlink sub-frame, includes mapping 16 physical control format indicator channel symbols into 4 resource element groups in the first orthogonal frequency division multiple symbol of the downlink sub-frame and transmitting the mapped 16 physical control format indicator channel symbols, wherein a structure is employed such that in a frequency domain, a distance between respective two resource element groups of the 4 resource element groups is an integer equal to or larger than (number of resource elements per resource block in frequency domain)/2.

    • A prism sheet, a back light unit and an LCD(Liquid Crystal Display) device having the same are provided to enhance the light concentrating property by concentrating light from an optical source on a visible surface of the LCD through the prism sheet. A back light unit for illuminating an LCD(Liquid Crystal Display) panel includes at least one optical source and a prism sheet(130b), wherein the prism sheet includes a base material(131a), a protection layer(131), a base film(132), a plurality of linear prisms(134). The prism sheet concentrates lights received from the light source on a visible plane of the LCD panel. The base material is made of light transparent resin. The protection layer includes a plurality of diffusion particles(131b) which are deployed on the parent material and diffuse light inputted to the base material.
