Abstract: A method of adjusting the coverage of a small cell for efficient use of cell resources in which the position of user equipment (UE) in the small cell is estimated using timing advance information of the UE, and the coverage is adjusted in consideration of a load state of the cell and a channel state of the UE.

Abstract: A touch sensor includes a transparent substrate, first electrode patterns formed on one surface of the transparent substrate, second electrode patterns formed to intersect with the first electrode patterns, the second electrode patterns spaced apart from the first electrode patterns, wiring parts formed on one end or both ends of the first electrode patterns and the second electrode patterns to electrically connect between the first electrode patterns and the second electrode patterns. The first and second electrode patterns comprise thin metallic wires conducting with the wiring parts. An area occupied by the thin metallic wire per unit area on the first electrode pattern may be different from an area occupied by the thin metallic wire per unit area on the second electrode pattern.
