A scheduling apparatus and method are disclosed. An embodiment of the invention provides a scheduling apparatus that includes: a scheduling group classification unit that classifies user terminals located within a serving cell of a base station into a multiple number of scheduling groups by using large-scale fading information of the user terminals; a transmission power setting unit that sets the transmission power of the user terminals for each of the classified scheduling groups; a scheduling period setting unit that sets the scheduling period for each of the scheduling groups by determining a resource element usage proportion for each of the scheduling groups based on the data rate of each of the scheduling groups and determining the data rate expected for all user terminals; and a resource element allocation unit that allocates resource elements used for each of the scheduling groups according to each of the determined scheduling periods.

Scheduling method and apparatus

Provided is an antenna structure which is capable of having sufficient antenna performance even in an antenna having a small cross-sectional area. The antenna of the present invention comprises: a ferrite sheet; and an antenna sheet (flexible printed circuit board) which has a spiral loop antenna pattern. The antenna sheet is folded and the ferrite sheet is inserted therein to form a folded antenna. The folded antenna is configured in such a manner that a longitudinal pattern of the spiral loop antenna pattern is disposed close to a longitudinal centerline portion of the ferrite sheet.
